Coloboma of the eye is visible in the retina as "hole" in its structure, and causes low vision, possible sensitivity to light and variance in size of the eyeball. [ 11 ] [ 12 ] The build-up of tissue in the liver, known as hepatic fibrosis , may cause symptoms such as jaundice , ascites , abnormal bleeding and enlarged spleen. [ 12 ]

Coloboma of optic nerve is a rare defect of the optic nerve that causes moderate to severe visual field defects. Coloboma of the optic nerve is a congenital anomaly of the optic disc in which there is a defect of the inferior aspect of the optic nerve. The issue stems from incomplete closure of the embryonic fissure while in utero.
A coloboma (from the Greek κολόβωμα, meaning "defect") [1] is a hole in one of the structures of the eye, such as the iris, retina, choroid, or optic disc.The hole is present from birth and can be caused when a gap called the choroid fissure, which is present during early stages of prenatal development, fails to close up completely before a child is born.

It is the most common glaucoma surgery performed and allows drainage of aqueous humor from within the eye to underneath the conjunctiva where it is absorbed.

A special procedure called vitrectomy replaced the tissue behind the lens with a saline solution. Within a few months, almost all patients went from having an average of 20/1290 vision to 20/20 ...
Glaucoma is a group of diseases affecting the optic nerve that results in vision loss and is frequently characterized by raised intraocular pressure (IOP). There are many glaucoma surgeries, and variations or combinations of those surgeries, that facilitate the escape of excess aqueous humor from the eye to lower intraocular pressure, and a few that lower IOP by decreasing the production of ...
