THIS IS PPT FOR GLAUCOMA

1. ANCHAL GUPTA

2. Glaucoma is a group of eye condition that damage the optic nerve. The optic
nerve sends visual information from your eye to your brain and is vital for
good vision.
Damage to the optical nerve is often related
to high pressure in your eye.
It is a symptomatic condition of the eye where the
IOP is more than normal (above 25mmHg).
Untreated of glaucoma leads to permanent damage of the optic nerve and
resultant visual field loss,which can progress
to blindness.
Glaucoma can occur at any age but is more common in older adults.
It is one of the leading causes of blindness for people over the age of 60.

3. RISK FACTORS
Genetic Factor: Family history
Aging: above 40
Eye trauma
Hypertension
Severe Myopia
Ocular surgery
Diabetics mellitus
Migraine headache

4. Emotional excitement
Caffeine consumption
Prolonged use of corticosteroid

5. Open angle glaucoma , the most common type in
United states, where 9 in10 people with glaucoma have
open –angle type.
Develops slowly and is a lifelong condition.
Has a wide and open angle b/w the iris and cornea.
 It is also called chronic open angle glaucoma
Angle-closure glaucoma ,a less common form of
glaucoma
It is also called acute glaucoma or narrow –angle
glaucoma .
Has a closed or narrow angle b/w the iris and
cornea
Developes very quickly.
Demands immediate medical attention.

6.  No symptoms in early stages
 Gradually ,patchy blind
spots in your side vision .
 Side vision also is known as
peripheral vision
 Head pain
 High intraocular pressure
 In later stages, difficulty
seeing things in your central
vision.
 Severe headache
 Severe eye pain
 Nausea or vomiting
 Blurred vision
 Eye redness
 Colored ring around
light

7. : decreases aqueous humor production ,
eg Timolol, betaxolol
Reduces IOP by facilitating the out flow of
aqueous humor .eg pilocarpin Carbacol .
inhibitor : Decreases the formation and secretion
of aqueous humor.eg Dorzolamide, Brinzolamide .
: Latanoprost , travoprost and bimatoprost .
: Timolol, Betaxolol and Levobunolol.

8. Timolol causes a reduction of the pressure within the
eye (intra ocular pressure). This effect is may result from a
reduction in production of the liquid (aqueous humor)
within the eye.
The precise mechanism of this effect is not known.
The reduction in intraocular pressure reduces the risk of
damage to the optic nerve and loss of vision in patients
with glaucoma.

9. It is prostaglandin analog.
It is believed to reduced the intraocular
pressure by increasing outflow of aqueous
humor .
