Role of Transpupillary Thermotherapy in Central Serous Chorio-Retinopathy

BackgroundTo assess the efficacy of transpupillary thermo therapy (TTT) in cases of chronic central serous chorio- retinopathy (CSCR).MethodsA prospective evaluation was carried out on 25 cases of chronic CSCR who were subjected to TTT. Resolution of CSCR and improvement in visual acuity was noted after six weeks of therapy.ResultOut of 25 patients, 13 (52%) had complete success (resolution of CSCR and improvement in visual acuity > 2 lines on Snellen's chart), 10 (42%) had qualified success (resolution of CSCR but no improvement in visual acuity) and two (8%) had failure to therapy (no resolution of CSCR or improvement in visual acuity).ConclusionTTT maybe a good modality in aiding resolution of subretinal fluid in cases of chronic CSCR. However, improvement in visual function is dependent upon integrity of photo receptor layer of retina which is not influenced by this modality. A controlled study could be undertaken to compare outcome of TTT with conservative management in cases of early CSCR such that deleterious effects of chronic CSCR on the retinal photoreceptor layer are avoided.
