[Central serous chorioretinopathy and systemic steroid therapy]

Area of Science:

• Ophthalmology
• Endocrinology
• Pharmacology

Background:

• Systemic corticosteroids are known to cause ocular toxicity, including posterior subcapsular cataracts and glaucoma.
• This study investigates central serous chorioretinopathy (CSC) as a potential ocular side effect of long-term steroid therapy.

Observation:

• Fourteen patients (9 male, 5 female; ages 39-55) developed CSC with serous macular detachment during systemic steroid treatment.
• Onset of CSC ranged from 6 days to 10 years after initiating steroid therapy, with higher doses correlating to earlier onset.
• Patients presented with rapid onset of blurred vision; detachment was bilateral in two cases.

Findings:

• Fluorescein angiography revealed a focal hyperfluorescent leak from the retinal pigment epithelium in most cases, without diffuse RPE degradation.
• Laser photocoagulation successfully treated five patients, leading to subretinal fluid resorption.
• Symptom resolution occurred in other patients upon reduction of steroid dosage.

Implications:

• This study highlights CSC as a significant ocular complication of systemic corticosteroid use.
• The findings suggest a link between steroid therapy and focal RPE leakage, characteristic of CSC.
• Understanding this association is crucial for managing patients on long-term steroid treatment and monitoring for visual disturbances.
