Central Serous Retinopathy

Central serous retinopathy (CSR) is a condition that leads to accumulation of fluid under the retina, and usually affects the central part of the retina known as the macula. It typically affects males more than females. The usual age of diagnosis is between 20-40 years old.

CSR typically presents as blurry central vision, that may be associated with visual distortion. Straight lines may appear kinked, bent or wavy.

While the cause of CSR is not known, a number of factors can exacerbate the condition. Steroid use, in the form of injections, tablets, inhalers or even creams, can make the condition and prolong its duration. Patients with high levels of stress or type.

A personalities have also been shown to have worse symptoms. Obstructive sleep apnoea may also play a role in this condition.

Most cases of CSR resolve spontaneously, usually within 2-3 months. However some patients are prone to recurrent episodes, either in the same eye or both eyes. If a case of CSR does not resolve within this time frame, it can lead to “chronic CSR”. This can be more difficult to treat. Argon laser photocoagulation to the area of leak may resolve the fluid, and may be suitable if the leakage point is away from the central vision. Intravitreal injection of medication may also improve fluid reabsorption. Photodynamic therapy (PDT) has been shown to be an effective treatment for this condition. Our retinal specialists can discuss the various treatment modalities with you in further detail.
