Treatment of glaucoma
Primary goal
Keep iop low enough to prevent further optic nerve damage
Maintain iop within normal range unlikely to cause damage and prevent blindness
Glaucoma surgical options
Laser trabeculoplasty Laser iridotomy Filtering procedure Trabeculectomy Drainage implants
Pharmacological therapy glaucoma
Used to help control iop
