Advantages:

To treat central serous chorioretinopathy (CSC) with subthreshold transpupillary thermotherapy (TTT) inducing less damage to the macula than laser photocoagulation.

Methods:

Ten eyes of 10 patients with persistent serous retinal detachment (SRD) secondary to CSC were treated with subthreshold TTT applied to the leakage area. TTT parameters were as follows: power 70 to 140 mW; spot size 0.6 – 1 mm; duration 60 s. Response to treatment was monitored by visual acuity and optical coherence tomography (OCT).

Effectiveness / Safety:

Visual acuity improved from 20/63 at presentation to 20/50 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 6 months. No visible scarring was observed in all cases.

Take home message:

TTT is an interesting therapeutic option for persistent serous retinal detachment secondary to CSC inducing less damage to the macula than laser photocoagulation.
