To evaluate the efficacy of subthreshold transpupillary thermotherapy (TTT) with infrared diode laser for the treatment of central serous chorioretinopathy (CSC) with extrafoveal leaks on fluorescein angiography.
Ten eyes of 10 patients with serous retinal detachment (SRD) secondary to CSC were treated with subthreshold TTT applied to the leakage area. In all eyes, leakage was extrafoveal in location. Our indications for treatment included: 1. CSC of at least 3 months’ duration or 2. CSC of less than 3 months’ but with visual acuity less than 20/40, or loss of vision in the fellow eye secondary to chronic CSC, or if the patient’s occupation required early recovery. TTT parameters were as follows: power 70 to 140 mW; spot size 0.6 to 1 mm; duration 60 s. Response to treatment was monitored by visual acuity and optical coherence tomography (OCT).
Mean visual acuity improved from 20/63 at presentation to 20/30 at 6 months. Complete resolution of SRD on OCT occurred in 5 eyes (50%) at month 1, in 9 eyes (90%) at month 3, and in all eyes (100%) at month 6. No visible scarring was observed in all cases. No other complications were recorded.
TTT resulted in improvement in visual acuity and resolution of SRD in CSC with extrafoveal leaks without inducing visible damage to the retina.
