Risk factors for primary open-angle glaucoma in subjects with ocular hypertension

Main: - Evaluate the differences between the cases afflicted with primary open-angle glaucoma (POAG) and the controls afflicted with isolated ocular hypertension (OHT) concerning the potential risk factors, including sociodemographic factors, systemic diseases and treatments in progress, family antecedents of glaucoma, the duration of the disease, the factors linked to the eye, nutritional factors and the exposure to environmental neurotoxic compounds. Secondary: - Derive a predictive function by using the significant risk factors, in such a way as to assist ophthalmologists in classifying patients having a hypertonia with a high risk of developing glaucoma
