Stellate foveal retinoschisis is considered the hallmark of X-linked retinoschisis. We describe the finding of unilateral retinoschisis with stellate foveal appearance in 2 females with myopia who had no evidence of familial disease. Optical coherence tomography (OCT) and fluorescein angiography were obtained in both cases. Neither patient had a family history of low vision, night blindness, or retinal detachment. Visual acuity in the affected eyes was 20/50 and 20/25, respectively. Both fellow eyes had normal fundi, except for mild myopic changes. With OCT, widespread retinal splitting was detected at the posterior pole in the affected eyes, whereas the fellow eyes were normal. In one case, OCT showed that foveal retinoschisis represented the macular involvement of a flat inferior retinoschisis, although this was not clinically apparent. Macular retinoschisis with stellate foveal appearance may rarely be associated with pathologic myopia. OCT was useful to establish the true extension of these macular changes.
星芒状黄斑视网膜劈裂被认为是X连锁视网膜劈裂的标志。我们描述了2例近视女性患者出现单侧视网膜劈裂并伴有星芒状黄斑外观的情况，她们没有家族性疾病的证据。对这2例患者均进行了光学相干断层扫描（OCT）和荧光素血管造影检查。两位患者均无视力低下、夜盲或视网膜脱离的家族史。患眼的视力分别为20/50和20/25。除了轻度近视改变外，双眼眼底均正常。通过OCT检查发现，患眼后极部存在广泛的视网膜劈裂，而对侧眼正常。在1例患者中，OCT显示黄斑视网膜劈裂是下方扁平视网膜劈裂累及黄斑区，但在临床上并不明显。具有星芒状黄斑外观的黄斑视网膜劈裂可能很少与病理性近视相关。OCT有助于确定这些黄斑病变的真正范围。
