[Dynamic phototherapy as a treatment for central serous chorioretinopathy].

PURPOSE: To analyze the angiographic and tomographic results and the visual acuity of a group of patients presenting acute or chronic serous central chorioretinopathy (CSCR) treated with dynamic phototherapy. This treatment was guided by ICG angiography data.

PATIENTS AND METHOD: We conducted a retrospective/prospective nonrandomized study on 31 eyes of 27 patients, including eight acute forms and 23 chronic forms. One or more spots were treated according to the age-related macular degeneration standard protocol on the zones of choroidal hyperpermeability highlighted by ICG angiography. The criteria for success were based on functional signs, visual acuity, persistence of a point of leakage in angiofluorographic follow-up at 3 months, and the OCT study of serous retinal detachment.

RESULTS: An increase in visual acuity (3.58+/-3.22 lines, p<0.0001) was observed for all forms of treated CSCR; 90.32% patients presented a reapplication of serous retinal detachment within a period of 7.28+/-3.93 weeks. No retinal pigmentary epithelium tear or choroidal neovascularization was observed. Recurrence occurred in 12.9% patients within a period of 28+/-16.24 weeks; only chronic CSCR cases were concerned. At 8+/-4.2 months, the visual acuity of the patients who had no recurrence remained unchanged (0.356+/-0.4 LogMAR or 20/50-20/40).

CONCLUSION: Although the number of patients included in this study is limited, dynamic phototherapy currently seems to be an effective and sure treatment of CRSC. A randomized study on a large series is necessary to confirm these results.
