Eye (Ophthalmology) Surgery
Eye surgeons perform exacting procedures to help people who have diseases of the eye. Unique procedures treat age-related macular degeneration, tumors of the eye, retinal and corneal disorders.
This procedure involves the surgical removal of the eyeball that leaves the eye muscles and remaining orbital contents intact.
The surgery is performed to remove large-sized eye tumors or as a result of traumatic injury when the eye cannot be preserved. In the case of tumors, the amount of radiation required to destroy a tumor of the eye may be too intense for the eye to bear. Within months to years, many patients who are treated with radiation for large ocular melanomas lose vision, develop glaucoma, and eventually have to undergo enucleation.
Various vitreoretinal surgical and laser approaches can restore, preserve and enhance vision for many eye conditions such as certain types of age-related macular degeneration, diabetic retinopathy, diabetic vitreous hemorrhage, macular hole, detached retina, epiretinal membrane and CMV retinitis.
The eye surgery includes a group of procedures performed deep inside the eye's interior with lasers or conventional surgical instruments.
The delicate surgery takes place where the gel-like vitreous and light-sensitive membrane retina are found.
Age-Related Macular Degeneration (AMD)
For patients with end-stage age-related macular degeneration, a new telescopic implant fits directly into the eye to improve vision. Eye surgeons are now performing this procedure for patients with a specific kind of blindness.
Wet Age-Related Macular Degeneration (AMD)
Photodynamic therapy (PDT) is a treatment for wet AMD.
In photodynamic therapy, a light-sensitive medicine is injected into the bloodstream. The medicine collects in the abnormal blood vessels under the macula. Laser light is then shone into the eye, and activates the medicine, causing it to create blood clots that block the abnormal blood vessels.
By sealing the leaky blood vessels, photodynamic therapy slows down:
- The buildup of fluid under the retina that distorts the shape and position of the macula.
- The growth of scar tissue and the abnormal membrane under the retina, both of which damage the cells in the macula.
