Study Notes
Glaucoma Overview
- Glaucoma is a disorder affecting the optic nerve.
- Increased intraocular pressure (IOP) damages the optic nerve, leading to vision loss.
- Normal IOP ranges from 10 to 20 mm/Hg.
Primary Glaucoma Types
-
Primary Open-Angle Glaucoma (POAG):
- Most common type.
- Aqueous humor outflow is reduced due to blockages in the eye's drainage system (Canal of Schlemm and trabecular meshwork).
- IOP increases gradually.
-
Primary Angle-Closure Glaucoma:
- IOP rises rapidly.
- The angle between the iris and sclera closes abruptly.
- Onset is sudden and urgent treatment is required.
Secondary Glaucoma
- Secondary glaucoma results from various factors, including:
- Trauma
- Eye surgery
- Eye tumors
- Uveitis
- Iritis
- Neovascular disorders
- Degenerative diseases
- Central retinal vein occlusion.
Glaucoma Importance
- Glaucoma is a leading cause of blindness.
- Early diagnosis and treatment are crucial to prevent vision loss.
