The choroid is a thin layer full of blood vessels that sits behind your retina, inside the wall of the eye. A choroidal effusion happens when extra fluid collects in a small potential space between the choroid and the tough outer coat of the eye (the sclera). Think of the eye’s layers like wallpaper over a wall: if water gets behind the wallpaper, it can bubble up. In the eye, that “bubble” is the choroid lifting away a little because fluid (or sometimes blood) has seeped in.
A choroidal effusion happens when fluid collects between the choroid and the white wall of the eye (sclera). Think of the eye like an orange: the choroid is a thin, blood-rich layer inside the peel. When that layer leaks fluid or when eye pressure is too low, the choroid balloons outward, creating bulges or domes. Doctors call those bulges choroidal detachments.
This fluid can push other parts of the eye forward, shallowing the front chamber and sometimes closing the drainage angle, which can raise eye pressure suddenly and cause pain and blur. In other people, the exact opposite is true: the eye pressure is too low (hypotony) after surgery or a leak, and that low pressure allows the choroid to swell up.
This fluid build-up can be watery (serous) or bloody (hemorrhagic). It may affect a small area or almost the whole back of the eye. The bulging choroid can push other parts of the eye forward, change vision, and sometimes raise the eye pressure or, in other situations, make it too low. A choroidal effusion is not the same as a retinal detachment, but the two can look similar to a non-specialist. Doctors use special eye exams and scans to tell them apart.
Pathophysiology
Fluid collects behind the choroid for a few main reasons:
Pressure changes: If the pressure inside the eye drops too low (called hypotony) after surgery or injury, the choroidal blood vessels can leak, and fluid seeps into that potential space.
Leaky blood vessels from inflammation: When the eye is inflamed (like in certain autoimmune diseases), tiny blood vessels in the choroid get leaky and fluid escapes.
Outflow blockage: If the outer coat of the eye (the sclera) is abnormally thick or stiff, or if the venous “drain pipes” are squeezed, fluid cannot get out easily, so it pools behind the choroid.
Medication reactions: Some medicines can cause the ciliary body (a ring of tissue that helps focus the lens and makes eye fluid) to swell and shift forward, which crowds the eye’s front “angle,” changes pressure dynamics, and encourages fluid to collect behind the choroid.
Bleeding: If a choroidal blood vessel breaks, blood can fill the space (a hemorrhagic choroidal detachment), which behaves like a very dramatic form of effusion.
Types of choroidal effusions
By content
Serous (fluid) effusion: Clear or yellowish fluid collects behind the choroid. This is the most common type related to low pressure or inflammation.
Hemorrhagic effusion (choroidal hemorrhagic detachment): Blood fills the space. This is more sudden, painful, and often related to surgery, trauma, or fragile vessels.
By timing
Acute: Happens suddenly over hours to days—often after eye surgery, trauma, or a new medication.
Chronic/recurrent: Builds slowly or keeps coming back—often with structural problems (like an unusually thick sclera) or long-standing inflammation.
By extent
Localized: Only a small area lifts.
Diffuse/total: Large areas or nearly all of the choroid are lifted.
“Kissing” choroidals: Opposite walls of the choroid bulge so much they touch inside the eye—this is an eye emergency.
By cause pattern
Hypotony-related: After surgery or injury with low eye pressure.
Inflammation-related: Because of diseases that inflame the eye.
Uveal effusion syndrome: A special condition where an abnormal sclera blocks fluid outflow from the choroid, sometimes seen in very small eyes (nanophthalmos).
Drug-induced: Triggered by certain medications that swell tissues inside the eye.
Causes of choroidal effusions
Low eye pressure after glaucoma surgery (trabeculectomy or tube shunt).
If the new drain works “too well” or a suture is too loose, pressure can fall. Low pressure lets choroidal vessels leak, and fluid collects behind the choroid.Wound leak or over-filtration after cataract or other intraocular surgery.
A small leak from the surgical wound can drop pressure and cause fluid to pool behind the choroid.Cyclodialysis cleft (from trauma or surgery).
This is a little gap that opens between the ciliary body and sclera. It creates a shortcut for fluid to escape the eye, dropping pressure and encouraging a choroidal effusion.Over-suppression of fluid production (medication related).
Too many pressure-lowering drops or pills can push the pressure very low, which again favors leakage behind the choroid.Uveal effusion syndrome (abnormal sclera).
The outer coat of the eye is too thick or stiff, blocking normal venous outflow from the choroid. Fluid has nowhere to go and collects behind the choroid.Nanophthalmos (very small eye with thick sclera).
Short, small eyes often have a thick sclera. This promotes the same outflow blockage and makes effusions more likely, sometimes repeatedly.Posterior scleritis (deep inflammation of the white of the eye).
Inflammation makes vessels leaky. The inflamed tissue hurts, and fluid leaks behind the choroid, causing pain and vision changes.Vogt–Koyanagi–Harada disease and other uveitides (eye inflammation).
These autoimmune conditions inflame the choroid. Leaky vessels let fluid escape, causing choroidal swelling and effusions.Choroidal tumors (like melanoma or metastases).
A tumor can irritate or crowd the choroid and its drainage, leading to fluid leakage and a local effusion.Malignant hypertension, pre-eclampsia/HELLP.
A sudden blood-pressure crisis can injure choroidal vessels (hypertensive choroidopathy). Injured vessels leak fluid behind the choroid.Topiramate-related swelling (and similar drugs).
Topiramate (a seizure/migraine medicine) can cause the ciliary body to swell. This pushes the lens-iris diaphragm forward, narrows the drainage angle, changes pressure, and can set off a choroidal effusion with sudden myopia (more near-sighted).Other sulfonamide-class drug reactions (e.g., certain antibiotics or diuretics).
A small number of people have an idiosyncratic reaction that swells the uveal tissues, causing effusion and angle crowding.Strong miotic drops (e.g., pilocarpine).
By pulling the ciliary body and iris forward, these drops can shallow the front chamber and promote fluid misdirection and choroidal effusion in sensitive eyes.After scleral buckle surgery (retina repair).
A tight buckle can slow choroidal venous return. That backup of blood increases leakage into the suprachoroidal space.After pars plana vitrectomy (retina surgery).
Early postoperative inflammation and pressure changes can allow fluid to collect behind the choroid.Systemic vasculitis (e.g., lupus, polyarteritis nodosa, Behçet disease).
Inflamed blood vessels leak more easily. When the choroid’s vessels are involved, effusions can occur.Hypoalbuminemia (low blood protein from nephrotic syndrome, liver disease, or malnutrition).
Low protein in the blood lowers “oncotic pressure,” so fluid leaves vessels more easily, including behind the choroid.Suprachoroidal hemorrhage (blood behind the choroid) from trauma or fragile vessels, sometimes with blood thinners.
This is the “bloody” version. It expands the same space and can be very painful, urgent, and vision-threatening.Infectious choroiditis (e.g., tuberculosis or syphilis).
Infections inflame the choroid, make vessels leaky, and can lead to effusions along with other retinal findings.Rapid pressure swings during/after eye procedures (e.g., laser or injections).
Abrupt changes can briefly stress choroidal vessels, and in vulnerable eyes this can trigger an effusion.
Common symptoms
Blurred or reduced vision.
The raised choroid and swelling disturb the retina’s normal shape, so the image is no longer crisp.Distorted vision (straight lines look wavy).
If the macula (the center of sight) is pushed or swollen, lines bend or look uneven (metamorphopsia).A dark shadow or curtain from the side.
A large effusion in the periphery can block side vision, creating a shadow people sometimes mistake for a retinal detachment.Sudden nearsightedness (myopic shift).
If the lens gets pushed forward by swollen tissues, the focusing power increases, so you suddenly need stronger minus glasses.Halos around lights.
Angle crowding and corneal swelling from pressure changes can create halos.Eye pain or a deep ache.
Inflammation, a tense hemorrhagic effusion, or high pressure can hurt—often as a deep, boring pain.Headache.
Eye strain, inflammation, or pressure problems can radiate as headache.Nausea or vomiting.
When pressure rises fast (like in angle closure), the body reacts with nausea.Red eye.
Inflammation and venous congestion can make the eye look red and irritated.Light sensitivity (photophobia).
An inflamed eye is often sensitive to light.A feeling of pressure or fullness.
People may say the eye feels “tight,” “full,” or “about to pop,” especially with large effusions.Tenderness to touch.
Pressing on the closed eyelid may be sore if the outer coats of the eye are inflamed (posterior scleritis).Floaters or hazy spots.
Inflammation and fluid shifts can cause little spots or haze drifting in vision.Loss of side vision or patchy blind spots.
Where the choroid bulges, the retina may not work normally, creating gaps in the visual field.Difficulty focusing for reading.
Subtle shifts in lens position and macular shape make near work hard and tiring.
Diagnostic tests
A) Physical exam
Visual acuity test (reading the eye chart).
This tells how much your central vision has changed and helps track recovery or worsening over time.External inspection and slit-lamp look at the front of the eye.
The doctor checks redness, swelling, tenderness, corneal clarity, and the depth of the front chamber (it can look unusually shallow if tissues have moved forward).Pupil examination (including looking for a relative afferent pupillary defect).
Pupil reactions show whether the retina or optic nerve is under stress; an abnormal response can suggest more than just fluid behind the choroid.Intraocular pressure measurement (tonometry) at the slit lamp.
Pressure may be low (hypotony) with serous effusions or high if the angle becomes crowded or closed; tracking this is critical.
B) Manual/bedside functional tests
Confrontation visual fields.
With simple finger counting, the examiner checks for side-vision loss that matches where the effusion bulges.Amsler grid.
A small square grid helps detect wavy lines and missing spots from macular involvement.Digital palpation of eye pressure (if a tonometer isn’t available).
A quick, gentle touch through closed lids can suggest if the eye is very soft (low pressure) or rock-hard (very high pressure), guiding urgent decisions.Extraocular movements and pain with movement.
Restricted or painful eye movements may point toward posterior scleritis or orbital congestion that can accompany effusions.
C) Lab and pathological tests
Complete blood count (CBC).
Looks for anemia, infection, or blood problems that might worsen bleeding or inflammation.Inflammation markers (ESR and CRP).
High levels support an inflammatory or autoimmune cause.Autoimmune panel (e.g., ANA, anti-dsDNA, ANCA) as guided by history.
Helps uncover diseases like lupus or vasculitis that can inflame the choroid.Infectious testing when appropriate (e.g., syphilis serology, TB tests).
Some infections can inflame the choroid; finding and treating them changes outcomes.Serum albumin and total protein.
Low protein levels make vessels leakier; this test helps explain persistent effusions in the right clinical context.
D) Electrodiagnostic tests
Electroretinography (ERG).
Measures how well the retina’s light-sensing cells work. It helps if vision is poor and imaging isn’t clear about the retina’s health under the effusion.Visual evoked potentials (VEP).
Assesses the visual pathway from eye to brain. It helps separate retinal problems from optic-nerve or brain causes of reduced vision.
E) Imaging tests
B-scan ocular ultrasound.
This is often the most important early test. It shows smooth, dome-shaped elevations of the choroid and can distinguish choroidal effusion from a retinal detachment. In big cases, the bulges may meet (“kissing” choroidals).Ultrasound biomicroscopy (UBM).
A high-frequency ultrasound for the front of the eye. It shows swollen ciliary body, forward rotation of the iris-lens diaphragm, and closed angles from drug-induced or inflammatory effusions.Optical coherence tomography (OCT) of the macula and choroid (often with enhanced-depth imaging).
OCT is like an optical ultrasound. It shows fluid under the retina, choroidal thickening, and macular changes that explain distorted vision.Fluorescein angiography (FA).
A dye test that photographs circulation in the retina, showing leakage patterns and helping to separate inflammatory fluid from other causes.Indocyanine green angiography (ICG) and/or axial-length biometry (A-scan) as indicated.
ICG highlights the deeper choroidal vessels to reveal choroidal inflammation and outflow problems. Axial-length measurement confirms a very short eye in nanophthalmos, which supports a uveal effusion syndrome diagnosis.

Prevention tips
Follow post-op instructions carefully (shields, drops, activity).
Report pain, halos, sudden blur, or nausea immediately after eye surgery.
Avoid rubbing or pressing on the eye during healing.
Manage blood pressure and general vascular health.
Keep protein intake adequate if you have kidney, liver, or gut issues.
Know your medication triggers (e.g., prior topiramate reaction) and wear a medical alert.
Discuss blood thinners with your doctors around eye surgery timing.
Do not miss follow-up visits; subtle hypotony can be silent early.
Use protective eyewear to prevent trauma.
Maintain smoke-free living for better microvascular health.
When to see a doctor
Immediately/urgent: Severe eye pain, sudden blur, halos with headache/nausea, eye feeling hard or very soft, or any rapid vision drop after surgery or trauma.
Soon (24–48 h): New wavy vision, persistent red eye, pressure or ache not improving with prescribed drops.
Routine follow-up: Any recent eye surgery or known uveitis/scleritis—go to all scheduled checks even if you feel fine.
What to eat and what to avoid
Eat balanced meals with lean protein (fish, legumes, eggs) to support healing.
Add leafy greens (spinach, kale) for lutein/zeaxanthin.
Include colorful fruits/vegetables rich in vitamin C (citrus, berries, peppers).
Use healthy fats with omega-3s (fatty fish, flax, walnuts).
Drink enough water; avoid dehydration and big fluid binges.
Limit salt to help prevent vascular congestion spikes.
Go easy on alcohol; avoid binges that swing hydration and pressure.
Moderate caffeine if you notice pressure or headache sensitivity.
Avoid ultra-processed foods high in sugar/salt that promote inflammation.
If you’re on blood thinners, keep vitamin K intake consistent (discuss with your doctor).
Frequently asked questions
Is a choroidal effusion the same as a retinal detachment?
No. A choroidal effusion is behind the retina (in the suprachoroidal space). The retina may stay attached, though vision can still blur.Can it go away on its own?
Yes—many serous effusions resolve once the cause is treated (e.g., stop a trigger drug, fix a leak, calm inflammation).Why did it happen right after my eye surgery?
Post-op eyes can have low pressure or inflammation, which lets the choroid balloon. This is a known, treatable complication.Is it dangerous?
It can be, especially if it causes angle closure (pressure spike) or blocks needed surgery. Prompt care keeps risks low.What does “kissing choroidals” mean?
The bulges touch each other inside the eye—usually a sign of a large effusion that may need more aggressive treatment.Are steroid drops safe?
They’re first-line for inflammation but can raise eye pressure or promote cataract if used long. Your doctor monitors and tapers them.Should I use pilocarpine if my eye hurts?
No. Miotics like pilocarpine can worsen effusion-related angle closure. Use the drops your doctor prescribes, often including a cycloplegic (e.g., atropine).Do I need surgery?
Not always. Many cases respond to medications and time. Surgery is for big, non-resolving, or hemorrhagic cases, or when vision is at risk.Can blood thinners cause this?
They can increase bleeding risk if an effusion turns hemorrhagic, especially around surgeries. Management is individualized with your doctors.How is it different from central serous chorioretinopathy (CSC)?
CSC is fluid under the retina from choroidal hyperpermeability; a choroidal effusion is fluid behind the choroid that pushes the choroid itself outward.Will my vision return to normal?
Often yes, if treated early and the macula wasn’t damaged. Healing time varies from days to weeks, sometimes longer after surgery.Can glasses fix the blur?
Glasses usually won’t fix blur from a bulging choroid. Vision improves as the effusion resolves.Could this happen again?
It can, especially if you have uveal effusion syndrome or need repeat surgeries. Good control of triggers and inflammation lowers the risk.Are supplements enough to treat it?
No. Supplements are adjuncts for overall eye health. The cause must be fixed (medications, leak repair, or surgery).What should I watch for at home?
Worsening pain, halos, nausea, sudden blur, or a feeling that the eye is too hard or very soft—seek urgent care.
