entral retinal artery occlusion (CRAO) is an ophthalmic emergency causing indolent sudden vision loss. 1 Among its long term complications, iris neovascularization with a rate of 1-20% is also seen. 2 Although neovascularization can be observed at any time, it is mostly seen between the second and the third months. 2,3 Neovascular glaucoma (NVG) might be the reason for loss of current visual acuity and intense pain. It is also a serious complication which impairs the quality of life of the

... nt. In cases of intense ischemia of retina, there is more risk for the development of neovascularization. 3, 4 Hyperbaric oxygen treatment as one of the promising treatment options for retinal artery occlusion provides increase in long-term visual acuity. 5 In the treatment of NVG developing after CRAO, applying pan-retinal laser photocoagulation and intravitreal anti-vascular endothelial growth factor (VEGF) injection are the treatment modalities in decreasing neovascularization. In this paper, possible risk factors for early neovascularization developing after CRAO and current NVG treatment methods are discussed through the presentation of two cases who developed NVG immediately after CRAO. A AB BS S T TR RA AC CT T Central retinal artery occlusion (CRAO) is an ophthalmic emergency which causes sudden loss of vision. One of its most serious complications is neovascular glaucoma (NVG), and frequently seen between mostly the second and third months after the diagnosis. In this study, 2 cases of immediately developing glaucoma after CRAO are presented and possible risk factors are discussed. Our first case who developed NVG within four weeks could not complete her treatment due to myocardial infarct during hyperbaric oxygen treatment. On the other hand, our second case was referred to hyperbaric oxygen treatment but her treatment could not begin due to a gynecological disease and she could not attend her regular follow-ups. When these two cases, having NVG within four week after CRAO are examined, it should be considered that early development NVG may occur immediately after CRAO as an additional disease, which may increase ischemia, in patients who are incompatible and not attending follow-ups regularly.
