As we knew, central serous chorioretinopathy is characterized by serous detachment of the sensory retina as a consequence of focal leakage of fluid from the choriocapillaris through a defect in the retinal pigment epithelium. This disease typically affects young to middle aged men and  may be related to life stress events. The patients present with the sudden onset of blurred vision, micropsia, metamorphopsia and central scotoma. Visual acuity if often only moderately decreased and may be improved to near normal with a small hyperopic correction.

Last week, I met a patient with CSC(central serous chorioretinopathy), who had been treated with Argon laser photocoagulation to short the duration of the sensory detachment and hasten the recovery of central vision. But the symptoms were remaining. I asked the patient to take the OCT examination. When the report came back, there still was liquid under the sensory retina. Now I am thinking, how many times we could use Argon laser photocoagulation to treat CSC? Would this increase the symptom severity or the rate of sub retinal neovascularization and chronic cystoid macular edema? :?
