PURPOSE: The aim of this study was to evaluate a scoring system for chronic open-angle glaucoma. The authors devised an empirical scoring system for grading the severity of the disease and correlated this with treatment. MATERIAL AND METHODS: Ninety patients were evaluated on 11 parameters: 1. family history of glaucoma: blindness (2), yes (1), no (1); 2. Age: infant (4), juvenile (4); 3. race: Caucasian (0), Asian (1), Afro-Caribbean (2); 4. myopia: 0-6 diopters (d) (1), 6-12 D (2), > 12 D (3); 5. pigment dispersion or pseucoexfoliation (1); 6. intraocular pressure without treatment > 33 mmHg (4), 25-30 mmHg (3), 20-25 mmHg (2); 7. corneal central thickness: < 500 μm (3), > 500 μm (0); 8. optic disc appearance: suspect (1), pathological (4); 9. visual field defect: early (1), moderate (3), advanced (5); 10. vascular risk factors: yes (1), no (0); 11. loss of eyesight in one eye due to glaucoma (4). Scoring values were 2-34. The authors correlated this score with patient treatment: medical or surgical, number of glaucoma medications. RESULTS: The patients were divided into three groups: group 1 (36 patients), score 0-8; group 2 (24 patients), score 9-13; group 3 (30 patients), score above 13. Distribution between patients treated with medicine (mean number of medications) and patients with filtering surgery was as follows: group 1, medical treatment with 1.63 ± 0.73 medications, surgery 4/36; group 2, medical treatment with 2.00 ± 0.7 medications, surgery 17/24; and group 3, medical treatment with 2.12 ± 0.67 medications, surgery 27/30. In group 1, 88% of the patients did not have filtering surgery, but 90% of the patients in group 3 did. CONCLUSIONS: This scoring system seems to be an easy and practical tool for evaluating chronic open-angle glaucoma, which could also be used to evaluate target pressure. Further studies are necessary to validate this system.
