Thirty patients (33 eyes) with central serous chorioretinopathy were treated with argon laser photocoagulation. Visual acuity improved in 28 eyes (85%) and remained the same in 5 (15%). In all cases symptomatic improvement occurred, and final visual acuity was 20/30 or better. No complications resulted from treatment. In deciding when to treat, one must consider the duration of a given episode, degree of visual impairment, visual needs of the patient and location of the leakage site. While argon laser therapy of central serous chorioretinopathy is effective and safe, inadvertent foveal photocoagulation and intraretinal macular absorption of argon laser energy are potential therapeutic hazards.
