A Clinical Study on Therapeutic Effect of the Argon Laser Photocoagulation on Central Serous Chorioretinopathy

ABSTRACT

In selected cases of central serous chorioretinopathy the pigment epithelial defect can be sealed with laser photocoagulation. The authors analyzed the effectiveness of laser photocoagulation on visual improvement and duration of the disease in laser treated group, as compared to untreated group, which represented na tural course of the disease. A verage healing time was 5.2 weeks in treated group and 13.9 weeks in untreated group, which revealed statistically significant difference between two groups(p<0.01). No difference was noted in visual outcome between two groups. The initial visual acuity was influenced by the type of dye leaking, the distance of leaking point from center of fovea and the size of sensory retinal detachment in fluorescein angiography. But the final visual acuity was only ihfluenced by the size of sensory retinal detachment. The number and location of leaking point did not influence the initial and final visual acuity in both treated and untreated group.
