Rhegmatogenous retinal detachment (RRD) is when the light-sensing layer at the back of your eye (the retina) peels away from the wall of the eye because a tear or hole lets watery fluid from inside the eye slip underneath it. “Rhegma” means tear. When fluid sneaks through a tear, it lifts the retina like wallpaper coming off a damp wall. The retina can’t work when it’s lifted, so vision fades or goes missing in that area—often like a “dark curtain” or “shadow” coming from the side. The retina is brain tissue. It needs to stay attached and nourished to work. If the central part (the macula) detaches, fine detailed vision can be permanently harmed. Quick treatment can save sight, especially if the macula is still “on.”
Most often, the jelly in the middle of the eye (the vitreous) naturally shrinks with age and pulls away from the retina (a normal change called posterior vitreous detachment, PVD). If the pull is strong at a weak spot—like lattice degeneration, an old scar, or thin retina—it can tear the retina. Then fluid slips under the tear, spreading the detachment.
Retinal detachment means the thin film at the back of your eye (the retina) has peeled away from the layer underneath it (the retinal pigment epithelium, RPE).
In rhegmatogenous retinal detachment (RRD), a tear or hole forms in the retina. Clear gel inside the eye (the vitreous) seeps through that opening and collects under the retina. This pocket of fluid slowly lifts the retina off its normal position. The retina needs to be flat and attached to work. When it lifts, the photoreceptor cells (the “light sensors”) stop getting oxygen and nutrients and your vision in that area goes dark or distorted. RRD is a medical emergency because the longer the retina is detached, especially at the macula (the center for sharp vision), the more vision you may permanently lose.
Key terms explained
Retina: A thin nerve layer lining the back of the eye. It turns light into signals for the brain.
Macula: The center of the retina that gives you sharp, detailed vision for reading and recognizing faces.
Vitreous: A clear gel that fills the back of the eye. With age, it becomes more watery and can pull on the retina.
Retinal break/tear/hole: A small opening in the retina. Through this opening, fluid can pass under the retina.
RPE (retinal pigment epithelium): The support layer under the retina. It helps “pump” fluid out from under the retina.
Posterior vitreous detachment (PVD): A common age-related change where the vitreous pulls away from the retina. It can be harmless, but sometimes it tears the retina.
Pathophysiology
Vitreous gel changes with age—it becomes more liquid and pulls away from the retina (PVD).
Strong attachment points (like areas of lattice degeneration) may resist this pull. The traction can tear the retina (a flap tear or a round hole).
Fluid slips through the tear and collects under the retina, peeling it off the RPE.
Gravity spreads the detachment: a tear on top of the retina often causes a shadow from below (like a curtain rising), and a tear below causes a shadow from above.
If not treated, scar tissue (called proliferative vitreoretinopathy, PVR) can form and shrink, pulling the retina even more and making surgery harder.
Types of Rhegmatogenous Retinal Detachment
Primary (idiopathic) RRD
Happens without a recent injury or surgery. Usually related to age-related vitreous pulling and a tear.Secondary RRD
Triggered by another factor—such as eye trauma, certain inherited conditions, or after eye surgery (often cataract surgery).Macula-on vs. Macula-off
Macula-on: The center of vision (macula) is still attached. Urgent surgery aims to keep central vision intact.
Macula-off: The macula has detached. Vision is already reduced; rapid surgery aims to restore as much as possible.
Acute vs. Chronic
Acute: Sudden onset over hours to days, usually with flashes/floaters and a quick “curtain” of vision loss.
Chronic: Slow, may be subtle for weeks. The detachment can be shallow, with pigment “tobacco dust” in the gel and more scar tissue (PVR).
Superior vs. Inferior
Superior: Tear is in the upper retina—fluid spreads quickly (gravity helps it move under). Shadows often start from below.
Inferior: Tear is below—fluid may spread more slowly. Shadows often start from above.
Extent and configuration
Local (small area) vs. extensive (multiple quadrants).
Bullous (high, balloon-like elevation) vs. shallow (low elevation).
Special tear patterns
Horseshoe (flap) tear: A flap of retina is pulled toward the vitreous; these leak fluid easily.
Atrophic round hole: Small, round opening, often in thin retina.
Giant retinal tear (≥90° of circumference): A very large tear; detachment can be rapid and complex.
Retinal dialysis: A tear at the ora serrata (retina’s front edge), often after trauma.
Pediatric or inherited-syndrome RRD
Occurs in conditions like Stickler syndrome; may be earlier in life and more complex.
Causes and Risk Factors
Age-related vitreous changes (PVD)
The most common driver. The gel shrinks and tugs, making tears more likely.High myopia (nearsightedness)
A longer eye stretches the retina, making it thinner and more tear-prone.Lattice degeneration
Thin, “lattice-like” patches at the retina’s edge where tears often start.Snail-track degeneration
Frosted-looking peripheral areas that are fragile and can form holes.Atrophic round retinal holes
Tiny round holes in thin retina that slowly let fluid pass underneath.Horseshoe (flap) tears from PVD
Strong vitreoretinal attachments tear into a flap that leaks fluid readily.Giant retinal tear
Very large tear (≥90°). Fluid enters quickly; detachment can spread fast.Retinal dialysis (often trauma-related)
The retina splits away at its front edge after blunt injury.Blunt eye trauma
A hit can cause vitreous traction and tears.Penetrating eye injury
Direct damage can create tears and allow fluid under the retina.Cataract surgery (pseudophakia)
Slightly raises lifetime RRD risk, especially with other risk factors.Nd:YAG capsulotomy after cataract surgery
Treats cloudy capsule but is linked with a small increased RRD risk.Aphakia (no natural or artificial lens)
Less common now, but historically increased risk.Family history of RRD
Some people inherit thinner retina or stickier vitreous attachments.Stickler syndrome
An inherited collagen disorder. Retinal tears and detachments can occur early.Marfan syndrome
Connective-tissue weakness and lens problems can increase RRD risk.Ehlers–Danlos syndrome
Fragile connective tissues may include fragile retina.Wagner or other vitreoretinal dystrophies
Inherited disorders of vitreous and retina that predispose to RRD.Previous RRD in the other eye
If one eye detached, the fellow eye has higher risk.Prior retinal tears or inadequate sealing
If previous tears weren’t fully sealed or new ones formed, another RRD can occur.
Symptoms
Flashes of light (photopsia)—brief streaks or lightning in side vision.
New floaters—dots, cobwebs, or a ring (Weiss ring) that wasn’t there before.
Sudden shower of tiny black spots—“soot in snow,” suggesting a tear with a small bleed.
A dark curtain or veil—a shadow moving in from one side, above, or below.
Peripheral vision loss—patch of side vision goes missing.
Blurred central vision—especially if the macula detaches.
Wavy or bent lines (metamorphopsia)—straight lines look distorted.
A fixed dark spot (scotoma)—a patch you can’t see through.
Reduced contrast or color brightness—things look dull in the affected area.
Difficulty reading or recognizing faces—if the center is threatened or involved.
Symptoms that progress over hours to days—the shadow often grows.
More flashes with eye movement—movement tugs on the tear and stimulates the retina.
Painless vision loss—RRD usually does not cause pain.
One-eye symptoms—RRD usually starts in one eye, but the other eye can be at risk later.
Floaters that change or clump—as blood or inflammatory cells move in the gel.
If you ever notice a new curtain, a sudden shower of floaters, or persistent flashes, get same-day eye care. Early repair protects vision.
Diagnostic Tests
Important note: RRD is mainly a clinical diagnosis made by an eye doctor looking at your retina. Some tests confirm the findings, map the detachment, or help with surgery planning.
A) Physical Exam
Visual acuity (Snellen/ETDRS)
Measures how clearly you see at distance. A drop—especially recent—raises concern for macular involvement.Pupil exam for RAPD (relative afferent pupillary defect)
Checks if one eye sends weaker signals. A significant detachment (or other retinal/optic nerve issue) can cause an RAPD.Confrontation visual fields
Simple side-vision check at the chairside. May reveal a field defect matching the “curtain.”Red reflex check
The doctor shines light to see the glow from the back of the eye. A detached area can look duller or gray, hinting at lost attachment.
B) Manual/Office Ophthalmic Tests
Direct ophthalmoscopy
A hand-held view through your pupil. Can show a tear or elevated, mobile retina if the view is clear.Slit-lamp biomicroscopy with 90D/78D lens
A microscope view of the retina. The doctor looks for tears, holes, subretinal fluid, tobacco-dust pigment, and whether the macula is on or off.Indirect ophthalmoscopy with scleral depression
A wide, bright view with a head-worn light. Gentle pressure on the sclera helps expose the far edge of the retina to find peripheral tears.Tonometry (intraocular pressure measurement)
RRD eyes can show slightly lower pressure than the fellow eye (not specific, but supportive).Kinetic/automated perimetry (e.g., Goldmann or Humphrey)
Maps your visual field more precisely to document the size and location of defects.Amsler grid (near-vision grid)
Simple square grid. Wavy or missing central lines suggest macular involvement (metamorphopsia/scotoma).
C) Laboratory / Pathological Tests
Labs don’t diagnose RRD directly, but they support surgical planning or look for underlying conditions when suspected.
Complete blood count (CBC)
Useful pre-op; checks anemia or infection risk.Coagulation profile (PT/INR, aPTT ± platelets)
Important if you’re on blood thinners or have a bleeding disorder before retinal surgery.Targeted genetic testing (e.g., Stickler, COL2A1/COL11A1)
Considered in early-onset, bilateral, or family-clustered RRD to confirm an inherited vitreoretinopathy.
D) Electrodiagnostic Tests
Full-field electroretinography (ffERG)
Measures overall retinal function. In chronic or complex RRD, a reduced signal can hint at prognosis.Multifocal ERG (mfERG)
Maps function in different retinal regions (especially macula). Helps estimate potential visual recovery.Electro-oculography (EOG)
Assesses RPE function. May be altered when the retina has been detached for longer or if there’s widespread RPE stress.
E) Imaging Tests
B-scan ocular ultrasound
Crucial when the view is blocked by blood or cataract. Shows a mobile, folded retinal membrane lifting off the back wall and can reveal tears or choroidal detachments.Optical coherence tomography (OCT)
Cross-section pictures of the retina. Defines whether the macula is on or off, shows subretinal fluid, and checks for epiretinal membranes or macular holes.Color fundus photography / ultra-widefield imaging
Documents the detachment, tear locations, and any lattice or thin areas. Helps track changes before and after surgery.Fluorescein angiography (FA)
Not required for every RRD but can help if the diagnosis is unclear, or when other conditions (like vascular leaks) are suspected. It outlines blood flow patterns and ischemia.
Non-pharmacological treatments and supportive measures
Important: These do not reattach the retina by themselves. Only surgery can fix RRD. But these steps protect the eye, reduce complications, and improve surgical outcomes before and after the operation.
Immediate eye protection (rigid shield, not a patch)
Purpose: Prevent accidental rubbing/pressure.
Mechanism: A hard shield keeps fingers and objects off the eye, lowering risk of bigger tears or infection.Urgent head positioning (as advised by your surgeon)
Purpose: Temporarily slow fluid from spreading under the retina.
Mechanism: Gravity can help keep the macula attached if the tear is positioned such that fluid movement is affected by head tilt.Activity restriction
Purpose: Reduce sudden vitreous traction and pressure spikes.
Mechanism: Avoid heavy lifting, high-impact exercise, and Valsalva (straining). Calmer eye motion = less pulling on torn edges.No contact lenses until cleared
Purpose: Limit infection/irritation.
Mechanism: Contacts can rub or trap microbes; pausing reduces risk before/after surgery.Stop eye rubbing
Purpose: Avoid mechanical stress on the tear.
Mechanism: Rubbing can increase vitreoretinal traction and worsen breaks.Protective eyewear (sports goggles) if trauma risk
Purpose: Prevent new injuries.
Mechanism: Polycarbonate shields absorb impacts that could cause fresh tears.Strict driving avoidance if vision is unstable
Purpose: Safety.
Mechanism: Field defects and reduced acuity raise accident risk; wait for your surgeon’s go-ahead.Pre- and postoperative education (“gas bubble rules”)
Purpose: Prevent dangerous pressure changes.
Mechanism: With a gas bubble in the eye, you must not fly and must avoid nitrous oxide anesthesia; education prevents catastrophic pressure spikes.Sleep positioning after surgery
Purpose: Keep the bubble or oil tamponade against the treated area.
Mechanism: Gravity holds the tamponade where the surgeon needs it, helping the laser/cryotherapy seal the tear.Postoperative activity plan
Purpose: Balance protection and recovery.
Mechanism: Gradually resume walking and light chores; avoid heavy lifting and swimming until cleared.Glycemic control in diabetes
Purpose: Lower risks of inflammation and scarring.
Mechanism: Better glucose control supports wound healing and reduces traction-type issues.Blood pressure moderation
Purpose: Reduce bleeding risk during/after surgery.
Mechanism: Controlled BP lowers choroidal hemorrhage risk.Smoking cessation
Purpose: Improve healing and microcirculation.
Mechanism: Smoking impairs oxygen delivery; stopping helps the retina and incisions heal.UV/bright light protection (sunglasses)
Purpose: Comfort and glare control, protect healing tissue.
Mechanism: Reduces photophobia and possible oxidative stress.Dry eye care (lubricant drops, warm compress)
Purpose: Comfort after surgery and with frequent drops.
Mechanism: Tears stabilize the surface, making drop therapy easier and preventing surface scratches.Infection hygiene
Purpose: Reduce postoperative infection (endophthalmitis) risk.
Mechanism: Clean hands, careful drop technique, avoid contaminated water (pools/hot tubs) until cleared.Safe return-to-work planning
Purpose: Match job demands to healing stage.
Mechanism: Desk work may be earlier; heavy labor later; protects against pressure spikes.Home hazard check
Purpose: Prevent falls with reduced vision.
Mechanism: Good lighting, remove trip hazards, use handrails.Low-vision strategies if recovery is partial
Purpose: Maximize function.
Mechanism: Magnifiers, high-contrast settings, text-to-speech tools, and orientation training.Psychological support and clear follow-up schedule
Purpose: Reduce anxiety, improve adherence.
Mechanism: Knowing what to expect (blurry vision with gas, position schedule, drop plan) improves outcomes.
Drug treatments used around RRD care
Note: Medicines do not reattach the retina. They support the eye before and after surgery, control pressure/inflammation, prevent infection, and reduce nausea/pain. Actual doses and timing vary; always follow your surgeon’s prescription.
Topical corticosteroid (e.g., prednisolone acetate 1% drops)
Dose/Time: 1 drop 4–8×/day, then taper over 2–4 weeks post-op.
Purpose: Reduce inflammation.

Dose/Time: Atropine 1 drop 1–2×/day; cyclopentolate 2–3×/day for several days.
Purpose: Rest the ciliary muscle, relieve pain from spasm, stabilize the iris.
Mechanism: Temporarily paralyzes focusing muscle; widens pupil.
Side effects: Light sensitivity, blurred near vision; systemic effects rare.Topical antibiotic (e.g., moxifloxacin 0.5% or ofloxacin 0.3%)
Dose/Time: 1 drop 4×/day for about 1 week post-op (per surgeon).
Purpose: Surface infection prevention.

Dose/Time: 4–8 mg by mouth or IV every 8–12 h as needed.
Purpose: Control nausea/vomiting that can raise eye pressure.
Mechanism: 5-HT3 receptor blockade.
Side effects: Headache, constipation.Analgesic (e.g., acetaminophen 500–1000 mg)
Dose/Time: 500–1000 mg every 6–8 h as needed (max per local guidance).
Purpose: Pain relief.
Mechanism: Central analgesic.
Side effects: Liver risk at high doses or with alcohol.Perioperative antiseptic (povidone-iodine 5–10% ophthalmic prep)
Dose/Time: Applied in clinic/surgery before procedures.
Purpose: Strong infection prevention on the eye surface.
Mechanism: Broad antimicrobial kill on contact.
Side effects: Temporary irritation; rare allergy.
(Other agents used selectively by specialists include intravitreal antibiotics if infection risk, or adjuvants during surgery; those are individualized.)
Dietary and supportive supplements
Honesty first: No supplement can repair a detached retina or replace surgery. These nutrients may support overall retinal health, healing, and metabolism. Check with your doctor if you take blood thinners, have kidney/liver disease, are pregnant, or have other conditions.
Lutein (10 mg/day)
Function: Antioxidant in the macula; filters blue light.
Mechanism: Neutralizes free radicals in retinal cells.Zeaxanthin (2 mg/day)

Function: Supports metabolism and healing.
Mechanism: Optimizes perfusion and drug distribution.
Regenerative/stem-cell”–related drugs
Important caution: There is no approved stem-cell or “regenerative” drug that reattaches an RRD. The following items are specialist, adjunct, or investigational approaches mainly aimed at preventing scarring (proliferative vitreoretinopathy, PVR) or studied in other retinal diseases. They are not standard self-care.
Intravitreal corticosteroids (e.g., triamcinolone)
Use: Surgeon-delivered adjunct to reduce inflammation; sometimes helps visualize vitreous during surgery.
Mechanism: Potent anti-inflammatory action; may reduce PVR risk.
Risks: IOP rise, cataract progression, infection risk (rare but serious).5-Fluorouracil (5-FU) ± low-molecular-weight heparin (intraoperative infusion, specialist use)
Use: Attempt to lower PVR formation in selected complex cases.
Mechanism: Antiproliferative effect on cells that form scar tissue.
Risks: Off-label; potential toxicity if misused; expert hands only.Methotrexate (intravitreal, specialist protocols)
Use: Adjunct in recurrent PVR (investigational/off-label).
Mechanism: Antiproliferative/anti-inflammatory; suppresses fibrocellular growth.
Risks: Retinal toxicity risk if dosing errors; specialist setting.Rho-kinase (ROCK) pathway interest (investigational)
Use: Studied for fibrosis/traction modulation.
Mechanism: Inhibits cell contraction and scarring pathways.
Status: Research; not routine for RRD.Anti-VEGF agents (e.g., bevacizumab) – limited/adjunct contexts
Use: Not for RRD itself, but may be used around coexisting vascular disease to reduce bleeding or edema.
Mechanism: VEGF blockade.
Risks: Off-label nuances; surgeon decision only.Cell-based therapies (RPE/photoreceptor precursors) – research in other diseases
Use: Trials in macular degeneration/retinal dystrophies; not standard for RRD.
Mechanism: Replace/support damaged retinal cells.
Warning: Avoid unregulated clinics; discuss only within recognized clinical trials.
Surgeries used to treat RRD
Core principle: Surgery seals the tear and keeps the retina pressed back against the wall of the eye until the natural pumping layers re-attach it.
Laser retinopexy or cryopexy (for retinal tears or small, localized detachments)
Procedure: In clinic or operating room, the doctor applies laser burns or freezing around the tear to weld the retina down.
Why: Seals edges so fluid can’t slip under. Used alone for tears; used with other surgeries for RRD.Pneumatic retinopexy
Procedure: In office or OR, a gas bubble (e.g., SF6 or C3F8) is injected into the eye. Laser or cryo seals the tear. You keep a strict head position so the bubble floats against the tear.
Why: The bubble pushes the retina flat while the seal forms. Best for selected, simple detachments with tears near the top.Scleral buckle
Procedure: A soft silicone band is stitched to the outside of the eye wall to indent (buckle) it inward under the tear. Laser/cryo seals the tear; the buckle reduces traction and supports reattachment.
Why: Very effective, especially in younger, phakic patients or complex tear patterns.Pars plana vitrectomy (PPV) with gas or silicone oil
Procedure: In the OR, tiny instruments remove the vitreous gel, release traction, seal the tear (laser/cryo), and fill the eye with gas (temporary) or silicone oil (longer-term) to hold the retina in place.
Why: Most common modern surgery for many RRDs, especially with multiple tears, posterior breaks, or cloudy media. Gas dissolves over weeks; oil may need later removal.Complex repairs (e.g., retinotomy/retinectomy, membrane peeling, encircling band)
Procedure: In challenging cases with scarring (PVR), surgeons may peel membranes, cut and flatten stiff retina (retinotomy/retinectomy), and place a full encircling buckle.
Why: To overcome severe traction and let the retina lie flat again.
Prevention strategies
Reality check: Not all RRD can be prevented. But you can lower risk and catch problems early.
Know the symptoms of tears/detachment (new flashes, many floaters, a curtain) and seek same-day care.
Dilated retina checks if you are high-risk (high myopia, family history, lattice degeneration, prior RRD, after cataract surgery).
Protective eyewear for sports, tools, or jobs with flying objects.
Treat retinal tears early with laser/cryo before a detachment forms.
Control diabetes and blood pressure to promote healthy retinal tissues.
Avoid eye trauma—seatbelts, helmets, safe play rules.
Follow post-op instructions after any eye surgery to reduce traction events.
Don’t ignore symptoms in the other eye—risk is higher after one RRD.
Avoid high-impact activities during acute PVD symptoms until your retina is checked.
Regular comprehensive eye exams from midlife onward, sooner if high-risk.
When to see a doctor—timing matters
Immediately (same day or emergency) if you notice:
Sudden flashes or a shower of floaters
A dark curtain or shadow in your side or central vision
Sudden blurry or crooked vision
Promptly (within days) if:
You had a recent eye injury, even if vision seems OK
You recently had cataract or other eye surgery and new floaters/flashes start
Routine monitoring if high-risk: your eye doctor will set an exam schedule.
What to eat and what to avoid (supportive diet for eye health)
Food won’t reattach a retina, but a heart- and brain-healthy diet supports healing and overall eye function.
Helpful foods to eat
Leafy greens (spinach, kale) for lutein/zeaxanthin.
Fatty fish (salmon, sardines) for DHA/EPA.
Citrus/berries for vitamin C.
Nuts and seeds (almonds, walnuts, flax) for vitamin E and omega-3s.
Colorful veggies (peppers, carrots) for carotenoids.
Legumes for zinc and plant proteins.
Whole grains for steady glucose.
Eggs (yolks have lutein/zeaxanthin).
Olive oil as main fat.
Plenty of water for hydration.
Foods/choices to limit or avoid
Trans fats and heavily fried foods (oxidative stress).
Excess sugar (glucose spikes harm microvessels).
Very salty foods (fluid retention, BP).
Excess alcohol (healing, medication interactions).
Ultra-processed snacks (low nutrients).
Smoking/vaping (not food, but huge negative).
Unregulated supplements that promise “cures.”
Grapefruit if your medications interact (ask your doctor).
Energy drinks if they trigger BP spikes.
Contaminated water (pools/hot tubs) until your surgeon clears you after surgery.
Frequently Asked Questions
Is a rhegmatogenous retinal detachment an emergency?
Yes. The faster the retina is reattached—especially before the macula detaches—the better the chance to save sharp vision.Will it hurt?
Usually no pain from the detachment itself. Some discomfort after surgery is normal and controlled with drops or pills.Can eye drops fix a detachment?
No. Drops help with inflammation or pressure, but surgery is what seals the tear and reattaches the retina.How do doctors choose the surgery?
They consider where and how big the tear is, how much retina is off, lens status (natural lens vs cataract surgery), presence of scarring (PVR), the clarity of the media, and your overall health. Many RRDs are treated with vitrectomy, some with pneumatic retinopexy, some with scleral buckle, and some combinations.What are the chances of success?
High reattachment rates (commonly over 85–90% with one operation; higher with additional procedures). Vision recovery depends on whether the macula was detached and for how long.Will my vision be the same as before?
If the macula stayed attached, vision may be close to baseline. If it detached, fine detail may remain reduced, even if the retina is successfully reattached.What is a gas bubble and what rules must I follow?
A temporary gas bubble holds the retina in place. You must keep specific head positions, do not fly, and avoid nitrous oxide anesthesia until your surgeon says the bubble is gone.Can I sleep on my back or side after surgery?
Follow the exact positioning your surgeon gives. It might be face-down, on the side, or alternating—positioning is crucial.What about silicone oil instead of gas?
Oil is used when longer support is needed; vision is blurry through oil, and a second surgery is usually needed to remove it later.Will I need a cataract operation later?
After vitrectomy, cataracts often progress faster, especially in older adults. Many people eventually need cataract surgery.What is PVR and why does it matter?
Proliferative vitreoretinopathy is scarring on the retina that can pull it loose again and make repairs harder. Surgeons use techniques and sometimes adjuncts to reduce PVR risk.Can it happen in my other eye?
Risk is higher in the fellow eye than average. Regular checkups and quick care for symptoms are important.When can I go back to work or exercise?
Many resume light desk work in 1–2 weeks, but heavy labor or contact sports may take longer. Your surgeon will tailor the plan.Can I drive?
Only when your vision meets legal standards and your surgeon says it’s safe—never with a fresh gas bubble unless vision is clearly adequate and permitted.What if I live far from a retina surgeon?
If you have symptoms, go to the nearest emergency/eye clinic immediately. Early diagnosis and urgent referral are key.
