Early Focal Laser Photocoagulation in Acute Central Serous Chorioretinopathy: A Prospective, Randomized Study

Abstract

Background and objective: To evaluate the role of early focal laser photocoagulation in acute central serous chorioretinopathy (CSC).

Patients and methods: A total of 58 eyes with acute naïve CSC (less than 2 months' duration) with focal leak on fundus fluorescein angiography (FFA) were randomized into either a laser or a sham laser group. Eyes with chronic CSC and subfoveal leak were excluded. Visual acuity assessment, microperimetry, optical coherence tomography, and FFA were done at baseline, 1 month (minus FFA), 3 months, and 6 months after treatment.

Results: There was a significant improvement in best-corrected visual acuity, low-contrast visual acuity, retinal sensitivity, and central macular thickness at all visits in both groups (P < .001); however, there was no significant difference between the groups regarding time of resolution. Four eyes in the sham laser group needed rescue laser compared with one eye in early laser group (P = .16).

Conclusion: Early laser photocoagulation is not superior to sham laser for acute CSC; therefore, observation appears to the safest and most effective strategy. [Ophthalmic Surg Lasers Imaging Retina. 2017;48:564-571.].
