RESUMO
BACKGROUND: We conducted this retrospective study to analyze the main characteristics of the disc cuppings in patients diagnosed with chronic open angle glaucoma. METHODS: Data of 489 patients seen in our department and presenting chronic open angle glaucoma were collected. All these patients entered our glaucoma criteria and had disc cupping examination by color stereophotography during the follow up period of 36 months. RESULTS: The sample for the whole comprised 489 patients, of whom 327 where men (67%) and 162 female (33%). Most of the patients are young, 68.97% less than 45 years old. The disc cuppings had various distributions: 28% at 0.4; 25.8% at 0.5; 19.3% at 0.6; 13.2% at 0.7; 10.7% at 0.8; and 4.3% at 0.9. The mean cupping in the left eye (0.6) was greater than that of the right eye (0.52); p = 0.001. There were also differences in the values of the mean cupping with the age (p = 0.0001). However, there was a correlation between the cuppings and the result of the automatic perimetry. CONCLUSION: This study demonstrated the importance of disc cup examination for the diagnosis, follow-up, and treatment of chronic open angle glaucoma in our populations.
