Bilateral parafoveal telangiectasis typically includes the presence of fluorescein staining of outer retinal capillaries, no macular ischemia, right-angled venules, and migration of pigment along these venules. In the bilateral form, atypical parafoveal telangiectasis with macular ischemia but without right-angled venules or migration of pigment along these venules has been reported in only five patients previously. An atypical case is presented of bilateral parafoveal telangiectasis complicated, not only by areas of macular nonperfusion, but also by peripheral ischemia with subsequent anterior and posterior segment neovascularization in the absence of any systemic abnormalities. As in previously reported cases, this patient had no evidence of right-angled venules or pigment migration. Pan-retinal photocoagulation resolved the rubeosis and caused regression of the retinal neovascularization.
双侧黄斑旁毛细血管扩张通常包括外层视网膜毛细血管荧光素染色、无黄斑缺血、直角小静脉以及色素沿这些小静脉迁移。在双侧形式中，之前仅有5例患者报告了伴有黄斑缺血但无直角小静脉或色素沿这些小静脉迁移的非典型黄斑旁毛细血管扩张。本文呈现了1例非典型病例，双侧黄斑旁毛细血管扩张不仅合并黄斑无灌注区，还合并周边缺血，随后在无任何全身异常的情况下出现眼前段和眼后段新生血管形成。与之前报道的病例一样，该患者没有直角小静脉或色素迁移的证据。全视网膜光凝消除了虹膜红变，并使视网膜新生血管消退。
