PURPOSE: The association of central retinal vein occlusion (CRVO) with primary open-angle glaucoma (POAG) or ocular hypertension has been reported, and lowering intraocular pressure (IOP) helps to improve the retinal circulation in eyes with CRVO. However, the clinical features of CRVOs with normal-tension glaucoma (NTG) are not well known. Therefore, we investigated Japanese CRVO patients with NTG. METHODS: We retrospectively investigated 234 CRVO patients over 5 years, with follow-ups of more than 12 months, and evaluated the prevalence of glaucoma. RESULTS: Of the 234 CRVO patients, 18 (7.7%) were diagnosed with NTGs (n = 10) or POAGs (n = 8). Seven POAG (87.5%) and 3 NTG (30%) patients had systemic hypertension. At the initial CRVO evaluation, 6 NTGs showed a significantly increased IOP; mean IOP was 13.3 mm Hg before CRVO, 16.2 mm Hg at CRVO, and 13.5 mm Hg at the final visit. CONCLUSIONS: The proportion of NTGs with systemic hypertension was low. IOP of NTG patients was significantly elevated at the initial CRVO evaluation, even in the presence of anti-glaucoma drugs.
