Evaluation of Color Vision in Patients with Glaucoma Suspect

PURPOSE: To assess color vision deficiency in patient with glaucoma suspect. METHODS: A total of 75 eyes (39 patients) with glaucoma suspect and Primary Open Angle Glaucoma as a control who fulfilled the inclusion/exclusion criteria were enrolled this observasional analytic with a cross sectional study. Color vision deficiency was assessed using Farnsworth Munsell D-15 test. Retinal nerve fiber layer thickness was performed with Spectral Domain-Optical Coherence Tomography. RESULT: 38/41 eyes with glaucoma suspect had no color vision deficiency; 2 eyes manifestated a tritan color vision defect; and 1 eye manifestated a protan color vision defect. There were no statistical correlation between glaucoma suspect and color vision deficiency. And there were no correlation between changes in RNFL thickness and the occurrence of color vision in patient with glaucoma suspect. CONCLUSION: Color vison deficiency tend to occur in patient with Primary Open Angle Glaucoma (p=0.059) compared to those with glaucoma suspects (p=0.344) in the correlation with Retinal Nerve Fiber Layer thickness.
