Twenty seven eyes treated for ischaemic central retinal vein occlusion with panretinal photocoagulation were reviewed. Prior to laser therapy anterior segment neovascularisation predominated (17 eyes) over posterior segment involvement (6 eyes). After photocoagulation anterior segment new vessels regressed or did not develop in the majority of cases. However, in five eyes previously absent posterior segment neovascularisation occurred. These results suggest that photocoagulation alters but does not eliminate retinal ischemia, thus modulating the neovascular response.
对27只接受全视网膜光凝治疗缺血性视网膜中央静脉阻塞的眼睛进行了回顾性研究。在激光治疗前，前段新生血管形成占主导（17只眼），而后段受累的有6只眼。光凝治疗后，在大多数病例中，前段新生血管消退或未形成。然而，有5只眼在之前没有后段新生血管的情况下出现了新生血管。这些结果表明，光凝改变但并未消除视网膜缺血，从而调节新生血管反应。
