Patient Education
Central Serous Retinopathy
Central serous retinopathy (CSR) occurs when fluid builds up under the retina, causing a small detachment at the macula. This creates blurry, distorted, or dim central vision.
Typical Symptoms
- Blurry or dim central vision, usually in one eye
- Straight lines appearing bent or distorted
- Objects appearing smaller than they should (micropsia)
- Colors appearing muted or faded
- A central gray or dark spot
How It's Diagnosed
OCT
Shows fluid accumulation beneath the retina and its extent. The primary tool for diagnosis and monitoring.
Fluorescein Angiography
Identifies the leak point(s) where fluid is entering the subretinal space — important for guiding laser or PDT treatment.
OCT-Angiography
A newer dye-free imaging technique that can detect changes in the blood vessels behind the retina associated with chronic CSR.
How It Affects Vision
CSR typically affects central vision for reading and fine detail work but spares peripheral vision. Acute episodes usually resolve spontaneously with good visual recovery. Chronic cases (lasting more than 4 months) may cause more lasting vision changes.
Treatment Options
Observation
The majority of acute cases resolve on their own within 3–4 months. Close monitoring with OCT is recommended.
Reducing Corticosteroid Exposure
If you use steroid medications (pills, creams, inhalers, or injections), reducing or stopping them — in coordination with your prescribing doctor — may help CSR resolve.
Photodynamic Therapy (PDT)
A low-dose light treatment using a light-activated drug that targets the abnormal blood vessels driving fluid leakage. Preferred for chronic cases.
Laser Treatment
Focal laser at the leak point can accelerate resolution in carefully selected cases where the leak is away from the center of the macula.
