DCR (Dacryocystorhinostomy) Surgery for Blocked Tear Ducts
Tears normally drain from the eye through small tubes called tear ducts, which stretch from the eye into the nose. If a tear duct becomes blocked or fails to open, tears cannot drain from the eye properly. The clogged or blocked tear duct may fill with fluid and become swollen, inflamed, and sometimes infected.
The primary goal of DCR surgery (also known as tear duct surgery) is to provide a pathway for drainage from the eye to the inside of the nose. DCR creates a new route for tears to drain from the eye.
Who Needs DCR Surgery?
DCR surgery is advised when the eye watering is excessive enough to interfere with your daily life. Tear duct surgery is also recommended in cases where patients have previously had an infection in the tear sac (acute dacryocystitis) as a result of the blocked tear duct as it can prevent repeated infections.
Orbital Decompression Surgery
Orbital decompression is a type of eye surgery used in cases of thyroid eye disease (also known as Grave’s eye disease) to treat the following symptoms:
• Bulging eyes (Exophthalmos)
• Inability to close eyes completely
• Dry eye
• Double vision
• Increased orbital pressure (caused by muscle swelling)
Orbital decompression helps to improve these symptoms by creating more space in the eye socket to allow the eyes to move back to a normal position and help prevents further vision loss.
Patients without thyroid eye disease who have similar symptoms are also candidates for the procedure.
Orbital Eye Socket Fracture Surgery
Eye socket fractures result from trauma to the bones that surround and protect the eye. Any of the bones surrounding the eye can be fractured, or broken during contact sports, at work, in car crashes, while doing home repair projects, or during a fight or violent assault.
Types of orbital fractures include: orbital rim fractures that affect the bony outer edges of the eye socket, blowout fractures that involve a break in the floor or inner wall of the orbit or eye socket, and orbital floor fractures that occur when a blow or trauma to the orbital rim pushes the bones back, causing the bones of the eye socket floor to buckle downward.
Orbital Tumor Surgery
Orbital tumor surgery is used to remove tumors located in the bony socket in the front of the skull that contains the eye (the orbit).
Eye Removal Surgery
Eye removal surgery may be needed in cases of a painful blind eye, eye cancer or following a severe injury or infection of the eye.
There are two main types of eye removal surgery, enucleation and evisceration.
Enucleation involves the removal of the eye (globe) while leaving the eye muscles and remaining orbital contents intact. The muscles that control eye movement are left intact and are resewn to the spherical implant (artificial eyeball). This type of ocular surgery is indicated for a number of ocular tumors, in eyes that have suffered severe trauma, and in eyes that are otherwise blind and painful.
An evisceration involves the removal of the eye’s cornea and contents, leaving the white part of the eye (scleral shell) and extraocular muscles intact. The implant is then placed into the scleral shell to which the muscles are still attached. The procedure is usually performed to reduce pain or improve cosmesis in a blind eye, as in cases of endophthalmitis unresponsive to antibiotics.
