Fourty-seven patients with central serous retinopathy analysed at Siriraj Hospital. Twenty-three eyes were treated by krypton laser photocoagulation. It was found that the duration of resolution of subretinal fluid and recovery of visual acuity was about 3-4 weeks. In most eyes, the visual acuity returned to 6/9 and 6/6. After treatment, changes in pigment at macular area and esidual symptoms such as metamorphopsia, micropsia of scotoma were found in some patients.
