Laser treatment of chronic central serous chorioretinopathy with a point of leakage in the subfoveolar zone without fluorescein angiography

Abstract

Aim. Develop a methodology and evaluate the clinical results of laser treatment of patients with chronic central serous chorioretinopathy in the presence of a leakage point in the foveola zone.

Methods. The results of patients (32 eyes) with central serous chorioretinopathy after laser exposure in the avascular area were analyzed. The best-corrected visual acuity in these patients before treatment was 0.7 to 1.0 (average 0.78±0.15) with a height of neuroepithelial detachment of 162 to 328 μm according to optical coherence tomography. No signs of choroidal neovascularization was detected in angio mode on optical coherence tomography. The treatment was performed with an Ellex Integre Pro Scan 561 nm. The follow-up examination was performed in 1 and 6 months.

Results. In 1 month, positive dynamics of both functional and anatomical parameters was noted in all eyes. According to the optical coherence tomography, a complete attachment of the neuroepithelium in the central zone of the retina occurred, detachment of the neuroepithelium was absent. Best-corrected visual acuity in 1 month after treatment increased to 0.89±0.08, in 6 months to 0.92±0.04. The study revealed a correlation between visual acuity and the central thickness of the retina in the fovea, there were no complaints about the appearance of scotomas after laser treatment in the foveola zone.

Conclusion. The developed techniqe of laser exposure on the foveola zone in case of chronic central serous chorioretinopathy with a 561 nm laser demonstrated high clinical efficacy and safety and can be recommended to all patients with central serous chorioretinopathy.
