Abstract

Purpose: To investigate correlations among the cup-to-disc ratio (CDR), intraocular pressure (IOP), and the occlusion site in branch retinal vein occlusion (BRVO).
Methods: This prospective study involved 62 eyes with a diagnosis of BRVO. Fundus photography, fluorescein angiography, Goldmann applanation tonometry, and optical coherence tomography were performed. Correlations among CDR, IOP, and the occlusion site were analyzed.
Results: A negative correlation was found between the occlusion site and IOP (p<0.001, Pearson’s correlation analysis) and between the occlusion site and CDR (p<0.001, Pearson’s correlation analysis). However, the correlation between IOP and CDR was poor (p=0.092, Pearson’s correlation analysis).
Conclusions: BRVOs with an occlusion site near the optic disc are associated with raised IOP and CDR values. This study suggests that the occurrence of BRVO with an occlusion site near the optic disc indicates that the patient should be evaluated for glaucoma. J Korean Ophthalmol Soc 49(7):1094-1100, 2008
