A Gundersen flap, also known as Gundersen's flap, Gundersen's conjunctival flap, or conjunctivoplasty, and often misspelled Gunderson, is a surgical procedure for correcting corneal disease. It involves excising a damaged section of cornea, and replacing it with a section (or "flap") of the patient's own conjunctiva .
Conjunctival concretions can be seen easily by everting the eyelid. The projecting concretions can be removed if they are causing concerning symptoms. Removal can be performed by an eye doctor. Sometimes just a needle or a scalpel is used to remove the concretion under local light anesthesia of the conjunctiva in adults.
There are three types of eye removal: [4] Evisceration – removal of the iris, lens, and internal eye contents, but with the sclera and attached extraocular muscles left behind; Enucleation of the eye – removal of the eyeball, but with the eyelids and adjacent structures of the eye socket remaining. An intraocular tumor excision requires an ...
An evisceration is the removal of the eye's contents, leaving the scleral shell intact. Usually performed to reduce pain in a blind eye. [38] An exenteration is the removal of the entire orbital contents, including the eye, extraocular muscles, fat, and connective tissues; usually for malignant orbital tumors. [39]
An initial pocket is created under the conjunctiva and Tenon's capsule and the wound bed is treated for several seconds to minutes with mitomycin C (MMC, 0.5–0.2 mg/ml) or 5-fluorouracil (5-FU, 50 mg/ml) soaked sponges. These chemotherapeutics help to prevent failure of the filter bleb from scarring by inhibiting fibroblast proliferation.
Ocular 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, improve cosmetic appearance in a blind eye, treat cases of endophthalmitis unresponsive to antibiotics , or in the case of ocular trauma.
Suture conjunctiva; Insert temporary ocular conformer until prosthesis is received (4–8 weeks later) After implant vascularization, an optional secondary procedure can be done to place a couple peg or post. Also under anesthesia: Create conjunctival incision at the peg insertion site; Create hole into implant to insert peg or post
Iridectomy - Removal of the affected piece of the iris; Choroidectomy - Removal of the choroid layer (the vascular tissue sandwiched between the sclera and the retina) Iridocyclectomy - Removal of the iris plus the ciliary body muscle. Eyewall resection - Cutting into the eye to remove a tumor e.g. melanoma. This operation can be quite ...
