Treatments of retinoschisis with multiple abnormal blood vessels in high myopia: a case report

Abstract

Abstract Background Retinoschisis is not an uncommon complication in patients with high myopia. And paravascular retinoschisis might be a precursor to myopic macular retinoschisis. However, few cases of retinoschisis near the vascular arcade with abnormal vessels have been reported. Such abnormal vessels may cause vitreous hemorrhage, and vision is severely impaired as the disease progresses. At the same time, due to the small number of reported cases, opinions on the treatment of these abnormal blood vessels are not unified. In this article, we reported two cases of high myopia with retinoschisis near the vascular arcade with abnormal blood vessels, and different treatments of three eyes of retinoschisis with abnormal blood vessels near the arcade in high-myopic patients to provide new evidence for the understanding of the diagnosis and treatment of this disease. Case presentation: This study included three eyes of two patients with high myopic retinoschisis with or without foveal detachment accompanied by retinoschisis at the vascular arcade with abnormal retinal vessels. Both patients were middle-aged women with high myopia. The eye with macular retinoschisis with fovea detachment was treated with vitrectomy combined with fovea-spared inner limiting membrane peeling and air tamponade, and the other two eyes were treated with focal retinal laser photocoagulation. The abnormal vessels in all three eyes completely regressed within 1 to 3 months after treatment. Morphological changes in the abnormal retinal vessels after the treatment were evaluated by color fundus photography (CFP), optical coherence tomography (OCT), optical coherence tomography angiography (OCTA) and fundus fluorescein angiography (FFA). Conclusions In this article, we report some clinical manifestations of retinoschisis with multiple abnormal vessels near the vascular arcade in high myopia and show that both laser and vitrectomy treatment can successfully regress abnormal vessels.
