Types of Glaucoma

Acute Angle Closure Glaucoma:

Acute closure of the peripheral drainage angle, characterized by a sudden increase in intraocular pressure.

Chronic Angle Closure Glaucoma:

The iris obstructs the eye’s drainage angle in a slow, progressive fashion.

Primary Open Angle Glaucoma:

The drainage angle is open but does not allow fluid to drain adequately for unknown reasons.

Pseudoexfoliation Glaucoma:

Deposits of a fibrillary material that may contribute to the obstruction of the fluid drainage from the eye.

Pigmentary Glaucoma:

Pigment dislodged from the iris obstructs the eye’s drainage structures.

Angle Recession Glaucoma:

Scar tissue from previous trauma obstructs the outflow of fluid.

Neovascular Glaucoma:

Various disorders cause blood vessels to proliferate on the iris and in the eye’s drainage structures.

Primary Infantile Glaucoma:

The eye’s drainage channels form abnormally during gestation.
