Choroidal neovascularization and myopic foveoschisis occurring at different times in a patient with degenerative myopia.

In this study, we presented the clinical and imaging findings and treatment results of a case with myopic choroidal neovascularization (CNV) and foveoschisis. A 45-year-old female patient presented with decreased vision in the left eye. The best corrected visual acuity (BCVA) was 20/40 in the right eye; in the left eye it was 20/200. Anterior segment examination was normal. Fundus examination revealed subretinal hemorrhage in the lower half of the fovea in the left eye. In the light of these findings, with the diagnosis of myopic choroidal neovascularization, the patient was injected with 2 doses of bevacizumab, one month apart. In the first month follow-up after treatment, BCVA was 20/64, bleeding regressed, and there was a window defect in the area corresponding to the bleeding in the control FFA. In the seventh month of follow-up, BCVA decreased to 20/80 and foveoschisis developed on Optical Coherence Tomography (OCT). The patient was informed about his disease; Pars plana vitrectomy (PPV) and internal limiting membrane (ILM) peeling were recommended. The patient did not accept surgery and was followed up at regular intervals. Degenerative myopia; CNV and Fuchs’ spots are a disease that causes a decrease in visual acuity due to reasons such as Lacquer fissure involving the fovea, myopic foveoschisis or a combination of these. Making the differential diagnosis of these conditions by using imaging methods is of critical importance in terms of visual loss.
