| Abstrakt: | Purpose: To present novel findings in stellate nonhereditary idiopathic foveomacular retinoschisis, including the largest series of optical coherence tomography angiography findings to date. Methods: A retrospective case series with multimodal imaging was obtained and reviewed. Results: All three patients were women, aged 59-63. Two cases were unilateral, and one was bilateral. Vision ranged from 20/20 to 20/60 in the affected eyes. Peripheral retinoschisis was observed in all three patients. All patients were followed for a minimum of 1 year. In one case, progressive macular retinoschisis leading to foveal involvement was observed over two years, with an associated vision decline from 20/25 to 20/60. Attempted interventions included topical dorzolamide in all cases and intravitreal bevacizumab in one patient; however, no treatment effect was observed. The foveal avascular zone size was within normal limits (mean 280 µ m). In all stellate nonhereditary idiopathic foveomacular retinoschisis eyes, the retinoschisis cavities were nonvascular. Conclusion: Novel findings regarding stellate nonhereditary idiopathic foveomacular retinoschisis include the progressive nature of foveal involvement and the lack of response to topical dorzolamide and intravitreal bevacizumab. Foveal avascular zone was normal in all eyes, consistent with the relatively preserved vision in these cases. Retinoschisis cavities were nonvascular in all eyes, a finding which may give insight into the mechanism of this disease. |
