▪Leads to increase in (IOP)
LEADING TO GLAUCOMA

10. Meaning of glaucoma
GLAUCOMA : -increase (iop) more than 21mmHg
-IT is called the silent thief of the sight
-it is one of the commonest cause of blindness
-it damages the optic nerve

11. Causes of glaucoma
▪- Obstruction or decrease in the
outflow of the aqueous humor.
▪-Pressure builds up and damages
the optic nerve.
▪-Optic nerve damage can occur at
different levels for different people.

▪-Red eyes
▪-vision loss
▪-Halos around lights
▪-Nausea and vomiting

14. -Gradual loss of peripheral vision
normal glaucoma blindness

15. detection
▪Tonometer:
▪measures pressure
▪Pachymeter:
▪measures corneal thickness
▪Visual field test:
▪measures peripheral vision
▪Ophthalmoscopy:
▪direct observation of optic nerve
▪Imaging Technology:
▪scans optic nerve and retinal nerve fiber

16. treatment
Increase fluid drainage or decrease fluid production.
*Medicated Eye Drops
