Detailed explanation-1: -Primary congenital glaucoma is usually inherited in an autosomal recessive pattern, which means both copies of the gene in each cell have variants.

Detailed explanation-2: -Glaucoma develops when the optic nerve becomes damaged. As this nerve gradually deteriorates, blind spots develop in your vision. For reasons that doctors don’t fully understand, this nerve damage is usually related to increased pressure in the eye.

Detailed explanation-3: -At first, glaucoma doesn’t usually have any symptoms. That’s why half of people with glaucoma don’t even know they have it. Over time, you may slowly lose vision, usually starting with your side (peripheral) vision-especially the part of your vision that’s closest to your nose.

Detailed explanation-4: -Glaucoma can be inherited as a mendelian autosomal-dominant or autosomal-recessive trait, or as a complex multifactorial trait.
