INTRODUCTION: The prevalence and etiology of neovascular glaucoma (NVG) as a complication of central retinal artery occlusion (CRAO) is a debated issue. According to some authors, NVG associated with CRAO always involves underlying chronic ocular ischemic syndrome (COIS) as a primum movens for CRAO. However, we describe 5 cases of NVG following CRAO with no underlying COIS, confirmed by carotid Doppler studies and ultrasound color Doppler imaging (USCDI) of the ophthalmic artery (OA). MATERIAL AND METHODS: We conducted a single-center retrospective analysis of the medical records of 5 consecutive patients who developed NVG following non-arteritic CRAO between July 2010 and July 2014. RESULTS: Five patients were included. All 5 patients were examined at the emergency room. The 5 patients had normal intraocular pressure and no intraocular neovascularization upon initial examination. They had no hemodynamically significant internal carotid artery stenosis, and the ophthalmic artery USCDI was normal. These 5 patients developed NVG subsequently to the CRAO. CONCLUSIONS: In our patients, carotid Doppler studies and USCDI of the OA ruled out COIS. Thus, COIS did not cause the NVG. CRAO may therefore lead to neovascular glaucoma without underlying COIS.
