Endoscopic Endonasal Ophthalmic Surgery

Dacrocystorhinostomy (DCR)

• The tears that wash over the eye, drain away through a system that runs from the corner of the eye to the inside of the nose. If there is a blockage in this system the eye can start watering and you may be more prone to infections.
• A DCR is a type of surgery that is used to treat blocked tear ducts in adults. It creates a new passageway between the tear duct sac and the nose, bypassing the blockage and allowing tears to drain normally again.
• Endoscopic DCR uses a telescope to locate the site of the blockage, which is then opened up surgically. It avoids a external scar on the face, near thr eye, thus scoring over External DCR Surgery.

Endoscopic Optic Nerve Decompression

• About 5% of severe head injuries will have concomitant injury to optic nerve, optic tract or optic cortex.
• Trauma to the Optic Nerve is the most common indication for Endoscopic Optic Nerve Decompression where the ENT surgeon helps the ophthalmic colleague to decompress the nerve by relieving pressure on the nerve which might be impinged with fractured bone fragments or blood clots.

Endoscopic Orbital Decompression

• Proptosis, an abnormal protrusion of eyeball, is commonly seen in Graves disease, orbital abscess and orbital haemorrhage.
• The operation is achieved either by removing a part of the wall(s) of the orbit and in some cases by excision of some of the fatty tissues.
