0 Normal intraocular pressure is 11-21 mmHg by tonometry.
0 Intraocular pressure tends to increase with age.
0 Humor aqueous is important in the formation and regulation of intraocular pressure.
0 humor aqueous; It is secreted from the non-pigmented ciliary epithelium in the ciliary process of the corpus ciliary.
0 It is poured into the ciliary body → posterior chamber → pupillary opening → anterior chamber → trabecular mesh → Schlemm's canal → venous system.
Fundus Examination
Optic disc (papilla)
• As the nerve fibers approach the papilla, they make thicker bundles.
• As a result of nerve atrophy, enlargement (excavation) of the optic pit is seen.
Papillae circumference
• Candle flame bleeding
• Glaucoma halo around papilla
• Retinal nerve atrophy
