        "abstract": "Purpose: The purpose of the study was to assess color vision (CV) and contrast sensitivity (CS) in patients with primary angle closure glaucoma (PACG) and primary angle closure (PAC) and to correlate these changes with age-matched controls. In addition, to asses this correlation with optical coherence tomography (OCT) retinal nerve fiber layer (RNFL).\n\nMaterials and methods: CV (using D-15 and Ishihara test) and CS (using Spaeth Richman Contrast Sensitivity Test [SPARCS] and Pelli Robson test) were analyzed in patients with PACG (Group 1) (33 eyes), PAC (Group 2) (27 eyes), and controls (Group 3) (60 eyes). OCT RNFL and Humphrey visual field testing was also done for cases and controls.\n\nResults: Out of a total of 33 eyes in Group 1, 2 (6%) eyes had no defect, 20 (60.6%) had protan defects, 2 (6%) had deutran defects, and 9 (27.3%) eyes had tritan defects. Of the 27 eyes in Group 2, 1 (3.7%) eye had no CV defect, 19 (70.3%) eyes had protan defects, and 7 (25.9%) eyes had tritan defects. None of the eyes in Group 2 had a deutran defect. Forty-seven (78.3%) eyes from Group 3 had no CV defect, 10 eyes (16.6%) had a protan defect, and 3 (5%) of the eyes showed a tritan defect. All Group 1 and Group 2 eyes had a C-Index of >1.4. Twenty-eight eyes had a total SPARCS score"
