Abstract:

Abstract Glaucoma is the first cause of irreversible blindness worldwide . Its prevalence in our country is 2% ; half of patients remain undiagnosed . Certain drugs can trigger and/or exacerbate glaucoma ; hence the importance of having knowledge of these drugs by Primary Care physician . In addition , the drugs used in the treatment of glaucoma , even topically , can have systemic side effects that should be also know to the Primary Care physician . An adequate knowledge of all the drug groups and the prescribing of the appropriate drug in patients with risk factors and underlying pathology , will enable the Primary Care physician to optimise the risk/benefit ratio in the therapeutic management of these patients . An update is presented on this ophthalmological disease , with special attention to its implications for pharmacological treatments .
