Glaucoma irreversible blindness

Glaucoma is one of the leading causes of irreversible blindness that does not show any symptoms initially and as the condition advances vision test reveals the condition. Changes in vision occurs gradually. It is a condition where the optic nerve that sends message to brain slowly show progressive damage.

Glaucoma is linked to buildup of pressure inside the eye. Hereditary is one of the reasons to develop glaucoma. Intraocular pressure damages optic nerve causing blindness. Since the damage is gradual, a person might not notice the change in vision unless the doctor says. Loss of vision, cloudy eyes, pain in eyes, sensitivity to light, appearance of black spots or halos around light are few symptoms. Over time person might lose peripheral vision (closest to nose).

Anyone can get glaucoma and some are at higher risk – those whose family history shows presence of glaucoma, diabetes, if person is aged 60 and above can get glaucoma. There is no prevention for glaucoma. Doctor can slow down the process of optic nerve damage by keeping eye pressure low, through laser treatment or through surgery. Regular eye examination is critical to see the progress of glaucoma.

Ophthalmologists recommend a comprehensive eye exam every 1 to 3 years for people 55 to 64 and every 1 to 2 years for people over age 65.
