[High blood pressure and glaucoma : an inextricable link].

The relationship between glaucoma and hypertension is complex. Intraocular pressure is the main modifiable risk factor for glaucoma. Literature describes hypertension as being linked to glaucomatous damage, although the mechanisms are not fully understood. Therefore, glaucoma screening is recommended for hypertensive individuals over 60 years old. The relationships between ocular, arterial pressure, and ocular perfusion pressure, and their impact on optic nerve perfusion, make coordinated management of these elements crucial. Hypertension, hypotension, extreme variability, nocturnal dipping, and overtreatment with antihypertensive drugs can increase the incidence and/or progression of glaucoma. This critical review discusses the causative, clinical, and therapeutic elements to consider in the management of these two pathologies.
