Bilateral Central Scotoma Due to CSCR in an Asthmatic Policeman

Central serous chorioretinopathy (CSCR) is a retinal condition characterized by fluid accumulation in the subretinal space, resulting in neurosensory detachment or pigment epithelial detachment. The risk factors associated with this condition include male gender, middle age, smoking, stress and use of corticosteroids. We report a case of CSCR in a 37-year-old policeman with hypertension and bronchial asthma. He presented with sudden onset of bilateral blurring of central vision for 1 day, worse over the left eye. There were no other significant eye complaints. He is an active smoker and has been on long-term corticosteroids for asthma. On examination, the visual acuity was 6/9 bilaterally. The anterior segment of both eyes was normal. Examination of the right fundus revealed a dome-shaped swelling inferior to the fovea, while the left fundus showed circular detachment of the neurosensory retina at the macula. He was diagnosed to have bilateral central serous chorioretinopathy. He was also counseled to stop smoking. The corticosteroids were continued due to the risk of precipitating an asthma attack if they were withheld. Upon his next review two months later, his condition remained stable. CSCR is usually a self-limited condition, with good visual outcome. A thorough medical, social and drug history should be obtained, and patients advised to modify their lifestyle to eliminate or reduce risk factors such as smoking, stress and corticosteroid use.
