Descemet’s membrane is a thin, strong layer at the back of the cornea. It sits just under the innermost cells of the cornea (the endothelium) and helps keep the cornea clear by supporting those cells. Descemet membrane detachment (DMD) means that this membrane has separated or peeled away from the stroma (the thicker middle layer of the cornea). When this happens, fluid can collect in the cornea above the detached membrane, causing swelling (corneal edema) and making vision blurry or distorted. If the detachment does not heal or is large, it can permanently damage vision unless treated. Most often, DMD happens after eye surgery, but it can occur for other reasons too. EyeWiki PMCPMC
Descemet’s membrane is a thin but critical layer on the back of the cornea, just in front of the eye’s fluid-filled chamber. It acts like a delicate basement membrane that supports the corneal endothelial cells—cells that pump fluid out of the cornea to keep it clear. Descemet membrane detachment (DMD) means this membrane has peeled away or separated from the underlying corneal stroma. When that happens, the pump function is disrupted, fluid builds up in the cornea, and the cornea becomes swollen, cloudy, and vision drops. DMD is most commonly seen after eye surgery—especially cataract surgery—but it can also happen after trauma, from surgical instrument manipulation, or even spontaneously in rare cases. Mild detachments sometimes heal on their own, but persistent or large separations can threaten sight if not fixed promptly. PMC EyeWiki
The separation creates a space where fluid can accumulate, and the overlying corneal layers become edematous. This swelling leads to blurred vision, and if untreated for long it can cause scarring or permanent endothelial damage. Timely identification and appropriate management distinguish between full recovery and lasting visual loss. PMC
Pathophysiology
The cornea must stay thin and clear to focus light properly. The endothelial cells and their basement membrane (Descemet’s membrane) pump out extra water to prevent swelling. When the membrane lifts off, the pump function fails in that area, water builds up, and the cornea becomes cloudy and thick. That swelling blocks light and reduces vision. If left alone, the membrane might reattach on its own if the detachment is small, but large or central detachments can cause long-term swelling, scarring, and even require transplant procedures. ScienceDirectLippincott Journalseyerounds.org
Types / Classifications of DMD
Doctors classify DMD in several ways depending on appearance, location, size, and behavior. Understanding the type helps decide if and how to treat it.
Peripheral vs Central DMD: If the detachment is away from the visual axis (peripheral), it often causes fewer vision problems and may heal on its own. If it involves the central visual axis, vision is more affected and early treatment is usually needed. Lippincott Journals
Symmetrical vs Asymmetrical (by area and shape): Some detachments appear in a balanced way around the surgical wound; others are irregular or large and cover more than half of the cornea. Larger or complete detachments (over half the cornea) are less likely to resolve without intervention. medsci.org
Planar vs Non-planar: Planar detachments lie flat and close to the stroma, while non-planar ones are more elevated with a gap between the membrane and underlying tissue. Non-planar detachments often need active intervention because fluid accumulates more. (This distinction is commonly used in surgical decision algorithms and imaging interpretation.) ResearchGate
Early vs Late Recognized: Some detachments are found immediately during or after surgery; others are only seen weeks, months, or even years later (especially after grafts), which can affect healing potential and scarring. Lippincott Journals
Scrolled or Rolled DMD: In some cases, the detached membrane curls or scrolls, making spontaneous reattachment difficult and often requiring more advanced surgical repair. PMC
Isolated vs Associated with Other Corneal Disorders: DMD can occur alone or in the setting of other diseases like corneal dystrophies or ectatic disorders where the membrane is already fragile. eyerounds.orgScienceDirect
Small (self-limiting) vs Large (vision-threatening): Small detachments, particularly if peripheral, often resolve without surgery. Large detachments, particularly central ones, usually need intervention to prevent permanent damage. PMC
Causes / Risk Factors of Descemet Membrane Detachment
Below are 20 causes or contributing factors. Each is explained simply so a reader can understand how it might lead to DMD:
Cataract Surgery (Phacoemulsification): The most common cause. Instruments and fluid currents during the procedure can accidentally separate Descemet’s membrane, especially if the incision or manipulation is rough. PMC
Faulty Surgical Technique / Instrument Trauma: Using blunt instruments, excessive force, or improper entry into the eye can tear or lift the membrane. PMCPMC
Inadvertent Aspiration during Irrigation/Aspiration: Suction devices can pull on the membrane if used too close or too aggressively, creating or enlarging a detachment. PMC
Glaucoma Surgery (e.g., Trabeculectomy, Deep Sclerectomy): Surgical manipulation near the corneal angle can destabilize or separate Descemet’s membrane. Lippincott Journals
Keratoplasty (Corneal Transplant) Complications: Procedures replacing or reshaping the cornea can weaken the bond and cause secondary detachments. PMC
Intraocular Lens Implantation Trauma: Placing or repositioning lenses inside the eye, especially in tight spaces, can damage the membrane. PMC
Intraocular Injections / Fluid Overload: Injecting substances into the anterior chamber or overly pressurizing the eye can mechanically separate the membrane. ResearchGate
Penetrating or Blunt Eye Trauma: Direct hits to the eye can shear or pull on the membrane, causing it to detach. EyeWiki
Chemical Eye Injury: Strong chemicals that inflame or damage the cornea can weaken the adhesion and lead to detachment. EyeWiki
Severe Corneal Infection (Keratitis): Infection can damage the underlying structure and cause breakdown, allowing fluid to separate the membrane. Cleveland Clinic
Corneal Ectatic Disorders (e.g., Keratoconus, Pellucid Marginal Degeneration): A sudden break in Descemet’s membrane in these cases can cause “acute hydrops,” a form of DMD with rapid swelling. eyerounds.org
Posterior Polymorphous Corneal Dystrophy: A congenital condition that changes the membrane’s structure and makes it more fragile, increasing risk of detachment. eyerounds.org
Fuchs Endothelial Dystrophy: The endothelium and its basement membrane are weakened, making separations more likely, sometimes even spontaneously. medsci.orgScienceDirect
Previous Corneal Surgery (e.g., Radial Keratotomy): Old surgical scars can create areas of weakness where the membrane can detach later. Lippincott Journals
Spontaneous Detachment in Predisposed Eyes (Age/Structural Weakness): Advanced age or congenital thinning/weakness of the membrane-stroma attachment can lead to detachment without clear trauma. PMCResearchGate
Inflammation of the Eye (Uveitis): Chronic inflammation can damage or loosen the membrane’s attachment. medsci.org
Eye Rubbing in Ectatic Disease: Vigorous rubbing in already structurally weak corneas (as in keratoconus) can precipitate membrane breaks and secondary detachment. eyerounds.org
Inadequate Wound Sealing After Surgery (Leakage): A leaking incision may cause pressure changes that pull on the membrane or prevent its reattachment. PMC
Preexisting Endothelial Cell Loss or Dysfunction: If the endothelial layer is already weak, minimal stress can produce detachment because adhesion and dehydration mechanisms fail. PMCScienceDirect
Complications during Descemet’s Membrane Endothelial Keratoplasty or Related Endothelial Procedures: Manipulating grafts or the native membrane can cause partial detachments. Lippincott JournalsScienceDirect
Symptoms of Descemet Membrane Detachment
Symptoms often result from corneal swelling, vision distortion, and surface irritation. Some small detachments may cause few or no symptoms, but larger or central ones usually produce noticeable problems.
Blurry or Decreased Vision: The most common symptom due to swelling blocking and scattering light. Lippincott Journalseyerounds.org
Delayed Visual Recovery after Eye Surgery: Vision does not improve as expected after procedures like cataract surgery because the cornea is hazy from the detachment. Lippincott Journals
Foreign Body Sensation: Patients feel like something is in the eye because the cornea surface becomes irregular and edematous. Lippincott Journals
Tearing / Watering: Reflex tearing occurs from irritation and surface disturbance. Lippincott Journals
Photophobia (Light Sensitivity): Swollen cornea and irregular optics make bright light uncomfortable. eyerounds.org
Halos Around Lights: Light scattering in the edematous cornea creates rings or flares, especially at night. eyerounds.org
Glare: Similar to halos, patients have trouble with bright light or oncoming headlights due to surface irregularity. eyerounds.org
Corneal Haze or Cloudiness (seen on exam but also perceived): The swelling makes the cornea look foggy. Lippincott Journals
Pain or Discomfort (especially if associated with epithelial bullae or secondary surface breakdown): Fluid blisters can form on the surface, causing pain. eyerounds.org
Feeling of Eye Fullness or Pressure: Some patients describe a mild pressure sensation from swelling or associated inflammation. eyerounds.org
Reduced Contrast Sensitivity: Difficulty distinguishing shades or fine detail because of light scattering. (Inferred from corneal edema’s optical effects.) ScienceDirect
Vision Fluctuation: Vision may change day to day or hour to hour as the detachment shifts or partially seals. PMC
Double Anterior Chamber Appearance (on exam, but patient may notice distortion): A clinical sign that corresponds to the patient’s subjective visual distortion. Lippincott Journals
Persistent Symptoms despite Standard Postoperative Care: When a typical postoperative course stalls, this is a red flag for underlying issues like DMD. PMC
Corneal Bullae Formation Leading to Intermittent Sharp Pain: Bubble-like elevations (bullae) form when the epithelium is stretched over fluid, sometimes bursting and causing pain. eyerounds.org
Diagnostic Tests
Overview: Diagnosis depends on seeing the detachment directly, assessing corneal swelling, and ruling out other causes of vision changes. Some tests are done in the clinic by looking or touching; others use instruments or labs. Below are 20 tests divided into the user’s requested categories, with explanation of why each is used.
A. Physical Examination Tests (direct clinical observation)
Visual Acuity Measurement: Basic test to quantify how much vision is reduced; helps track improvement or worsening. PMC
Slit-Lamp Examination (Narrow Beam): The main tool to directly see the detachment edges, corneal edema, and any double anterior chamber or scrolls of membrane. Lippincott Journals
Corneal Clarity Assessment: Observing haze, localized edema boundaries, and comparing clear versus swollen areas gives clues to the presence and extent of DMD. Lippincott Journals
Anterior Chamber Depth Assessment (clinically by comparing both eyes): A very shallow or abnormal chamber might suggest fluid shifts or complications related to DMD. PMC
Intraocular Pressure (IOP) Measurement: Elevated or low pressure can accompany secondary effects and can influence the decision and timing of intervention. MDPI
B. Manual / Bedside Tests (clinician-applied maneuvers or simple adjuncts)
Fluorescein Staining: Helps rule out epithelial breakdown or corneal surface defects that may mimic some symptoms, clarifying that the problem is deeper (i.e., DMD). eyerounds.org
Seidel Test: Checks for leaking wounds from recent surgery; wound leaks can alter internal eye pressure and affect membrane apposition. PMC
Gonioscopy: Though primarily for angle assessment, it can help evaluate whether surgical incisions or manipulations near the angle contributed to trauma leading to DMD. eyerounds.org
Gentle External Pressure / Observation of Membrane Movement: Sometimes the clinician can observe subtle shifting of the detached membrane with small positional changes, helping to gauge its configuration (planar vs non-planar). (This is more observational and used in experienced hands.) ResearchGate
Epithelial Bullae Inspection (manual palpation with minimal pressure): Detecting bullae formation on the surface can indicate chronic corneal edema secondary to unresolved DMD. eyerounds.org
C. Laboratory and Pathological Tests
Corneal Scraping and Microbial Culture/PCR (if infection suspected): If the cornea is inflamed or infection cannot be excluded, cultures help rule out infectious keratitis masquerading as or complicating DMD. Cleveland Clinic
Endothelial Cell Evaluation (specular microscopy—although imaging, also informs pathological status): Assesses the density and health of endothelial cells; preexisting damage increases risk for DMD and influences prognosis. ScienceDirect
Blood Tests for Systemic Conditions (when underlying disease is suspected): Conditions like autoimmune inflammation may weaken corneal structures; inflammatory markers or connective tissue disease panels can be used in atypical cases. (This is more indirect and used when a systemic contributor is suspected.) Lippincott Journals
Anterior Chamber Tap and Analysis (rare): If there is unusual fluid accumulation or suspected secondary causes affecting the cornea, sampling can help rule out intraocular inflammation or infection. PMC
D. Electrodiagnostic Tests (not standard for DMD but used in differential workup)
Visual Evoked Potentials (VEP): If vision loss is severe and unclear, VEP can help rule out optic nerve or central problems as contributors, ensuring that corneal pathology (like DMD) is the primary cause. ScienceDirect
Electroretinography (ERG): Rarely used directly for DMD, but in complex visual loss cases, ERG ensures that the retina is functioning so that treatment focus stays on the cornea. ScienceDirect
Corneal Nerve Function Testing (e.g., esthesiometry) as an adjunct: While not electrical in the classic sense, it gauges surface sensitivity; decreased sensation may alter healing or contribute to misperception of discomfort, helping complete the clinical picture. eyerounds.org
E. Imaging Tests
Anterior Segment Optical Coherence Tomography (AS-OCT): The gold standard imaging test for detailed visualization of the detachment’s location, depth, shape, and extent. It guides decisions on whether to intervene and how. oftalmoloji.org
Ultrasound Biomicroscopy (UBM): High-frequency ultrasound gives cross-sectional images of the anterior segment, useful in dense edema where OCT may be limited, especially for total or complex detachments. medsci.org
Confocal Microscopy / High-Resolution Corneal Imaging: Provides microscopic views of the cornea and can help assess the interface, endothelial status, and subtle configuration of detachments when clarity allows. ScienceDirect
Non-Pharmacological Treatments
Each is explained with description, purpose, and mechanism in plain English.
Observation with Close Monitoring
Description: Watching mild or small DMD for spontaneous reattachment without immediate intervention.
Purpose: To avoid unnecessary procedures if the membrane will reattach by itself.
Mechanism: Some detachments seal as natural healing and endothelial pump action gradually removes fluid; small planar separations often resolve over days to weeks. PMC
Patient Positioning (Supine Posture)
Description: Keeping the patient lying on their back, sometimes with slight head positioning, after surgery or descemetopexy.
Purpose: To help an injected air or gas bubble press the membrane back against the cornea.
Mechanism: Gravity helps the bubble tamponade (press) the detached Descemet’s membrane into place so it can reattach. PMC
Anterior Segment Optical Coherence Tomography (AS-OCT) Guided Monitoring
Description: Using high-resolution imaging to see the detachment clearly.
Purpose: To measure size and depth, decide timing for intervention, and guide repair.
Mechanism: Noninvasive cross-sectional imaging shows whether the membrane is flat, bulging, or reattaching, so clinicians can choose conservative vs active therapy. MDPI
Gentle Handling During Intraocular Surgery (Preventive/Minimizing Injury)
Description: Surgeons use soft techniques, avoid abrupt fluid currents, and protect the endothelium during cataract or other anterior segment surgeries.
Purpose: To reduce the risk of creating a DMD in the first place.
Mechanism: Minimizing mechanical stress, sudden pressure changes, or sharp instrument contact reduces tears in Descemet’s membrane. BioMed Central
Use of Dispersive Viscoelastic Agents During Surgery
Description: Injecting viscous material that protects internal structures during surgery.
Purpose: To cushion the corneal endothelium and reduce shearing forces that can detach the membrane.
Mechanism: The viscoelastic buffers mechanical trauma and maintains space during maneuvers, lowering iatrogenic strain on the membrane. BioMed Central
Controlled Fluidics and Balanced Irrigation in Surgery
Description: Managing infusion and aspiration settings to avoid sudden pressure spikes.
Purpose: To prevent sudden shifts that might cleave Descemet’s membrane.
Mechanism: Stable anterior chamber dynamics reduce shear and hydraulic stress on the membrane. BioMed Central
Avoiding Eye Rubbing Postoperatively
Description: Counseling patients not to touch or rub eyes after surgery.
Purpose: To prevent mechanical dislocation or exacerbation of a detachment.
Mechanism: External pressure transmitted through eyelids can move internal structures; avoiding it lowers risk of worsening or new detachment.
Use of Protective Eyewear/Shielding After Surgery
Description: Wearing an eye shield, especially while sleeping or in crowded environments.
Purpose: To prevent accidental trauma or rubbing that could provoke or worsen a DMD.
Mechanism: Physical barrier reduces risk of external force reaching cornea.
Reduction of Intraocular Pressure Spikes (Non-pharmacologic like gentle activity)
Description: Advising patients to avoid heavy lifting, straining, or Valsalva maneuvers post-op.
Purpose: To prevent transient rises in eye pressure that could separate a fragile membrane.
Mechanism: Pressure spikes can push fluid between layers and promote detachment; minimizing them preserves adhesion.
Early Identification and Prompt Referral
Description: Educating surgeons and clinics to recognize symptoms and signs of DMD quickly.
Purpose: To intervene before the detachment enlarges or corneal decompensation sets in.
Mechanism: Timely action avoids chronic edema and fibrotic changes that are harder to reverse. MDPI
Use of Venting Incisions Along with Pneumatic Tamponade
Description: Tiny incisions in cornea to allow trapped fluid to escape when air/gas is injected.
Purpose: To flatten the detachment by decompressing fluid pocket.
Mechanism: Fluid egress reduces the barrier between Descemet’s membrane and stroma, assisting reattachment. MDPI
Controlled Reformation of Anterior Chamber (with non-drug viscoelastics)
Description: Manually reforming the chamber to press the membrane and re-establish normal anatomy before gas tamponade.
Purpose: To create space for air bubble and reduce collapsed areas that impede healing.
Mechanism: Structural restoration aids apposition of the membrane to its bed.
Patient Education on Warning Symptoms
Description: Teaching patients to report vision changes, pain, or cloudiness promptly.
Purpose: So that detachments are caught early when non-surgical or minimally invasive options are most effective.
Mechanism: Early reporting shortens delay to repair, reducing chronic damage.
Use of Low-Light Activity Early Post-op
Description: Avoiding high visual strain in the first days.
Purpose: To reduce blinking-induced micro-trauma and patient anxiety that might provoke rubbing.
Mechanism: Less disturbance to healing tissue gives time for natural adhesion if mild.
Temperature and Humidity Control for Comfort
Description: Keeping environmental conditions from drying the ocular surface.
Purpose: To support epithelial integrity so that the front layers of cornea do not become irritated, indirectly aiding overall healing.
Mechanism: A stable ocular surface avoids reflex tearing or rubbing that could destabilize deeper layers.
Use of Artificial Tears (Preservative-Free) for Surface Support (if not counted as “drug” in context)
Description: Lubricating the eye to reduce discomfort and reflex behaviors.
Purpose: To prevent secondary surface irritation that might interfere with recovery.
Mechanism: Enhanced comfort reduces blinking force and rubbing.
Avoidance of Contact Lens Use During Recovery
Description: Removing or not using contact lenses until full healing.
Purpose: To prevent mechanical disturbance of the healing cornea.
Mechanism: Lenses can shift, adhere, or introduce microtrauma, so abstaining supports stability.
Supportive Vision Aids (Temporary)
Description: Using magnifiers or large-print materials to reduce strain while vision is blurry.
Purpose: To help patients function without manipulating or stressing the eye.
Mechanism: Less need to squint or press on eyelids.
Limiting Exposure to Irritants (Smoke, Dust)
Description: Staying in clean air environments early post-op.
Purpose: To prevent reflex tearing or rubbing caused by irritation.
Mechanism: Reducing triggers of eye discomfort indirectly protects the deeper structure.
Structured Follow-up Scheduling
Description: Pre-arranged examinations in the first 1–2 days, then weekly until resolution.
Purpose: To ensure timely detection of progression or need for escalation.
Mechanism: Regular checks prevent missed worsening and allow switching from observation to active repair.
Note: Some of these overlap with prevention; in practice the lines blur because gentle surgical technique and early detection both prevent progression and treat early detachments. BioMed CentralMDPI

Surgical or Procedural Treatments
Pneumatic Descemetopexy (Intracameral Air or Gas Injection)
Procedure: A small amount of air or longer-acting gas (e.g., SF6 or C3F8) is injected into the anterior chamber so it floats up and presses the detached Descemet’s membrane back onto the stroma.
Why Done: This is the first-line surgical repair for most persistent DMDs because it physically re-apposes the membrane to allow reattachment. PMC
Venting Incisions with Air Tamponade
Procedure: Tiny incisions (venting) are made to drain fluid trapped under the detached membrane, combined with air to push the membrane flat.
Why Done: Helps in cases where fluid pocket prevents simple bubble tamponade from working; venting allows escape of the barrier fluid, improving reattachment. MDPI
Descemet Membrane Endothelial Keratoplasty (DMEK)
Procedure: Transplantation of a donor Descemet’s membrane with endothelium only in place of the patient’s diseased layer.
Why Done: For chronic, large, or irreversibly decompensated detachments or failed repairs; replaces the damaged endothelial/Descemet layer with healthy tissue for optical clarity and pump function. DMEK offers faster recovery and better visual outcome than older lamellar techniques. PMCMDPI
Descemet Stripping Automated Endothelial Keratoplasty (DSAEK)
Procedure: Transplantation of a thicker donor graft including posterior stroma, Descemet membrane, and endothelium.
Why Done: Alternative when DMEK is not feasible; used for endothelial failure or persistent complications including complex detachments, offering structural support though with slightly slower visual recovery. PMCMDPI
Penetrating Keratoplasty (Full-thickness Corneal Transplant)
Procedure: Full-thickness removal of the central cornea and replacement with a donor corneal button.
Why Done: Reserved for advanced cases where the cornea has scarring, longstanding edema, or prior graft failures making layer-specific procedures insufficient. Provides structural and optical rehabilitation when other methods fail. PMC

Excessive Vitamin A Megadoses without Guidance – Risk of toxicity and paradoxical harm. EyeWiki
Trans Fats / Highly Processed Fats – Pro-inflammatory.
Unbalanced High Omega-6 Intake (e.g., some vegetable oils) – May promote inflammation if not countered with omega-3s.
Caffeine Overuse (if leading to dehydration) – Can mildly affect ocular surface in sensitive individuals.
Foods with Known Allergens (if patient has ocular allergy history) – Avoid triggers that cause rubbing or inflammation.
Supplements or Herbs Without Doctor Approval – Could interact with eye medications or impact healing unpredictably.
Frequently Asked Questions (FAQs)
What causes Descemet membrane detachment?
Most often it happens after eye surgery (especially cataract surgery), from blunt or accidental trauma, or rarely spontaneously due to weak adhesion. Surgical manipulation, sudden pressure changes, and instrument contact are common triggers. PMCCan DMD heal by itself?
Yes, small and planar detachments sometimes reattach without surgery, especially if observed early and the eye is positioned properly. Larger or deep detachments usually need intervention. PMCWhat is the first-line treatment for persistent DMD?
Pneumatic descemetopexy (air or gas bubble injection) is the common first active repair to physically press the membrane back. PMCIs surgery always needed?
No. Mild cases can be monitored. Surgery is indicated if detachment is large, not improving, centrally located, or causing significant vision loss. MDPIWhat are the risks of descemetopexy?
Risks include increased eye pressure, infection, bubble-related visual disturbances, and failure requiring repeat intervention or further surgery. PMCWhat happens if DMD is left untreated?
Chronic corneal edema, scarring, endothelial cell loss, and permanent vision impairment can occur, sometimes necessitating full transplantation. PMCCan regenerative therapy help DMD?
Yes. New treatments like cultured endothelial cell injection with ROCK inhibitors, autologous serum, and biologics (e.g., amniotic membrane) support healing and restore function in select cases. PMCScienceDirectWill I need a full corneal transplant?
Only if previous repairs fail, or there is long-standing damage, scarring, or decompensation. Lamellar grafts (DMEK/DSAEK) are preferred before full-thickness transplant if possible. PMCMDPIHow long does recovery take?
With successful descemetopexy, vision can begin improving in days; full stabilization may take weeks. Advanced surgeries like DMEK have faster and better visual recovery than older grafts. MDPICan the membrane detach again?
Recurrence is uncommon if properly repaired, but risk increases if underlying risk factors remain or if the eye experiences trauma again. Proper follow-up reduces chance of missing early signs. MDPIAre there foods or supplements that help healing?
Yes. Vitamin C, A, zinc, copper, omega-3s, lutein/zeaxanthin, and collagen-supporting nutrients help support structural repair and reduce inflammation. EyeWikiOptometry TimesWhat should I avoid after eye surgery to prevent DMD?
Avoid rubbing the eye, heavy lifting or straining, sudden head movements, trauma, and non-prescribed eye drops; follow positioning instructions if you had air/gas injection.Do I need to worry about infection after treatment?
Yes. Prophylactic antibiotics are commonly used, and signs like discharge, severe redness, or pain should prompt immediate return. American Academy of OphthalmologyCan high eye pressure affect DMD healing?
Yes. Elevated intraocular pressure can push fluid under the membrane or inhibit adhesion, so pressure control is part of supportive management. SAGE JournalsIs this condition painful?
It can cause mild to moderate discomfort, especially if associated inflammation or increased pressure is present. Severe pain may suggest complications like infection or acute pressure spikes and deserves urgent evaluation.
