Enucleation is the removal of the eye that leaves the eye muscles and remaining orbital contents intact. This type of ocular surgery is indicated for a number of ocular tumors , in eyes that have sustained severe trauma, and in eyes that are otherwise blind and painful.
Sympathetic ophthalmia (SO), also called spared eye injury, is a diffuse granulomatous inflammation of the uveal layer of both eyes following trauma to one eye. It can leave the affected person completely blind. Symptoms may develop from days to several years after a penetrating eye injury. It typically results from a delayed hypersensitivity ...

Phthisis bulbi is a shrunken, [1] non-functional eye. It may result from severe eye disease, inflammation [2] or injury, or it may represent a complication of eye surgery. [3] Treatment options include insertion of a prosthesis, which may be preceded by enucleation of the eye. [4] [5]
Enucleation of an eye and, similarly, retinal damage, leads to a cascade of events in the cortical areas receiving visual input. Cortical GABAergic (GABA: Gamma-aminobutyric acid ) inhibition decreases, and cortical glutamatergic excitation increases, followed by increased visual excitability or even spontaneous activity in the visual cortex ...
Corneal cross-linking involves application of riboflavin solution to the eye that is activated by illumination with UV-A light for approximately 30 or fewer minutes. The riboflavin causes new bonds to form across adjacent collagen strands and proteoglycans in the stromal layer of the cornea , which recovers and preserves some of the cornea's ...
Trabeculectomy is a surgical procedure used in the treatment of glaucoma to relieve intraocular pressure by removing part of the eye's trabecular meshwork and adjacent structures. 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.
An evisceration is the removal of the eye's contents, leaving the scleral shell and extraocular muscles intact. [1] [2] The procedure is usually performed to reduce pain or improve cosmesis in a blind eye, as in cases of endophthalmitis unresponsive to antibiotics. [1] [2] An ocular prosthetic can be fitted over the eviscerated eye in order to ...
