Dry Eyes

ROLE OF TEARS

INCREASED EYE PRESSURE:
Elevated intraocular pressure (I0P) is a primary risk factor for glaucoma. When the fluid inside the eye fails to drain properly, pressure builds up, damaging the optic nerve over time.


AGE:
Advancing age is a significant risk factor for glaucoma. Individuals over the age of 60 are at a higher risk of developing the condition, with the risk increasing with each decade of life.


FAMILY HISTORY:
Genetics play a crucial role in glaucoma. If you have a family history of the condition, you may be at a higher risk of developing it yourself.


ETHNICITY:
Certain ethnic groups, such as African Americans and Hispanics, have a higher predisposition to glaucoma and are more likely to experience severe vision loss from the disease.

PREVENTION

OF DRY EYES

SURGERY
Laser surgery such as trabeculoplasty or iridotomy is done to reduce the fluid blockage and eye pressure using lasers. .

Conventional surgery such as microsurgery is done to drain the fluid and ease pressure by creating a new channel near the drainage canal.

DRY EYE TEST

Schirmer’s test is done to detect production of tears. An abnormal result will signify dry eyes.


. How is Schirmer’s test done?
Schirmer’s test is done in an eye clinic/hospital.
