A condition where pressure inside the eye rises to the point of causing damage to the optic nerve with associated loss of vision
Glaucoma
It usually affects both eyes and it is the leading cause of blindness in the world
Glaucoma
Pathophysiology
Two accepted theories regarding how increased IOP damages the optic nerve in glaucoma
Pathophysiology
Suggests high IOP damages the retinal layer as it passes through the optic nerve head
Damages the retinal layer
Direct Mechanical Theory
Pathophysiology
Suggests high IOP compresses the microcirculation in the optic nerve head, resulting in cell injury and death
Compresses the microcirculation in the optic nerve
Indirect Mechanical Theory
