title: [Scoring system for chronic open glaucoma].
abstract: OBJECTIVE
  The aim of this study was to evaluate a scoring system for chronic open-angle glaucoma. We devised an empirical scoring system grading severity of the disease and correlated this with treatment.
  
  
  METHODS
  and methods: Ninety patients were evaluated on 11 parameters: 1) Family history of glaucoma: blindness (2), yes (1) no (1); 2) Age: infantile (4), juvenile (4); 3) Race: Caucasian (0), Asian (1), Afro-Caribbean (2); 4) Myopia: 0-6 diopters (1), 6-12 diopters (2),>12 diopters (3); 5) Pigment dispersion or pseudoexfoliation (1); 6) Intraocular pressure without treatment:>30 mmHg (4); 25-30 mmHg (3), 20-25 mmHg (2); 7) Corneal central thickness:<500 micro m (3),>500 micro m (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. We correlated this score with patient treatment: medical or surgical, number of glaucoma medications.
  
  
  RESULTS
  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: 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 had filtering surgery.
  
  
  CONCLUSIONS
  This scoring system seems to be an easy and practical tool to evaluate chronic open-angle glaucoma, which could also be used to evaluate target pressure. Other studies are necessary to validate this scoring system.
