OBJECTIVE: To observe the changes in contrast sensitivity (CS) and color vision in patients with primary acute angle-closure glaucoma (PACG). METHODS: CS and color vision tests were performed in 35 patients (35 eyes) with preclinical stage of PACG, 32 patients (32 eyes) with acute attack stage of PACG and 15 normal subjects (30 eyes). Then patients were followed up 1 month (31 eyes) and 3 months (28 eyes) after operation. RESULTS: The results of CS and color vision tests were abnormal in PACG patients when they were compared with those of normal people. The threshold of CS at 18.0 c/d was increased (P < 0.01) and color vision was abnormal (P < 0.01) in the preclinical stage patients. The threshold of CS at 12.0 c/d and 18.0 c/d were increased (P < 0.01) and color vision was abnormal (P<0.01) in the patients 15 d after operation. CONCLUSION: Both CS and color vision are high sensitive parameters for visual function evaluating of glaucoma. LA: Chinese
