10 Different Types of Glaucoma And How To Identify Each One

4. Congenital Glaucoma

Babies are affected by congenital glaucoma. It transpires because of a lack of complete formation of the drainage canals, creating increased pressure and optic nerve damage. When it is diagnosed, in most cases in the first year of life, it can be treated early on with surgery and medications. Typically, there is some loss of vision. Signs in babies and young children include enlarged eyes, tearing, cloudy eyes, and sensitivity to light.

3. Normal-Tension Glaucoma (NTG)

NTG is also known as low-tension or normal pressure glaucoma because the pressure in the eye is not increased significantly. The main cause is the optic nerve becoming damaged, but the mystery lies in how it becomes damaged without the pressure. The cause remains unknown, but those at higher risk appear to have a family history of it, be of Japanese heritage, or are affected by systemic heart disease. It is diagnosed by examination of the optic nerve.
