Abstract Details

Purpose:

to compare the efficacy of conventional 532 nm laser photocoagulation (LC) of the extrafoveal leakage on FA as a monotherapy with conventional 532 nm LC of the extrafoveal leakage in combination with subthreshold Micropulse yellow 577 nm LC of the area of neurosensory retinal detachment with an individualized selection of energy in the treatment of central serous chorioretinopathy.

Setting:

Center of Eye Microsurgery, Kyiv, Ukraine

Methods:

The retrospective comparative study included 30 patients (30 eyes) with central serous chorioretinopathy (CSC) with neurosensory detachment (NSD) and extrafoveal angiographic fluorescein leakage. The control group 15 patients (15 eyes) was treated using conventional laser 532 nm photocoagulation of leakage as a monotherapy. In the main group, 15 patients (15 eyes) received conventional laser 532 nm photocoagulation of leakage in a combination with subthreshold 577 nm Micropulse LC at the area of neurosensory retinal detachment. All patients underwent a complete ophthalmological examination and microperimetry, Amsler test, color fundus photo, spectral optical coherence tomography (OCT Heidelberg Spectralis), fluorescein angiography (FA), fundus autofluorescence. Minimum follow-up period was 6 months.

Results:

VA improved in 14 eyes (93%) in the main group and in 13 eyes (87%) in the control group after 1 month (p >0.05). All eyes had neurosensory detachment (NSD) at baseline. At the final visit all eyes had resolution of the NSD according to spectral domain OCT, with a statistical significant reduction in central macular thickness (p < 0.05). However, a complete regression of exudative changes in the macular region according to FA and resolution of the NSD according to OCT of the study group came sooner than in the control group, 3 weeks and 4 weeks respectively (p < 0.05).

Conclusions:

Combination of conventional 532 nm LC of extrafoveal leakage with subthreshold micropulse 577 nm LC of the area of neurosensory retinal detachment showed greater efficiency than conventional 532 nm LC of the leakage as a monotherapy in the treatment of CSC.
