Age-related Macular Degeneration (AMD or ARMD)

Age-related macular degeneration (AMD or ARMD) can cause blurriness or darkness in the center of your vision. People affected by AMD may have problems reading, driving & performing activities that require clear central vision.

Argus® II Retinal Prosthesis System (Argus II)

Retinal implant for individuals with late-stage retinitis pigmentosa. If you have late-stage retinitis pigmentosa (RP), you may be a candidate for the Argus® II Retinal Prosthesis System, a retinal implant that could provide partial sight for individuals with the disease. The Argus II is sometimes refered to as the 'bionic eye."

Cystoid Macular Edema (CME)

Cystoid macular edema or CME, is a painless disorder which affects the central retina or macula. When this condition is present, multiple cyst-like (cystoid) areas of fluid appear in the macula and cause retinal swelling or edema.

Cytomegalovirus Retinitis (CMV Retinitis)

Cytomegalovirus (CMV) Retinitis is a virus that may infect the retina and potentially cause irreversible vision loss due to retinal detachment or destruction. It is most often diagnosed in patients with a severely compromised immune system, including those with AIDS or those on chronic immunosuppressive therapy following organ transplantation.

Detached Retina (Retinal Detachment)

A detached retina occurs when the retina is pulled away from its normal position in the back of the eye. A detached retina is a serious problem that can cause blindness unless it is treated. If any part of the retina is lifted or pulled from its normal position, it is considered detached and will cause some vision loss.

Diabetic Retinopathy

Diabetic retinopathy is caused by changes in the blood vessels of the retina. When these blood vessels are damaged, they may leak blood and grow fragile new vessels. When the nerve cells are damaged, vision is impaired. These changes can result in blurring of your vision, hemorrhage into your eye, or, if untreated, retinal detachment.

Dietary Supplements and Age-Related Macular Degeneration

An large scale national study sponsored by NEI revealed that individuals taking supplements with high levels of nutrients—such as vitamin C, vitamin E, beta-carotene, and zinc— can significantly reduce the risk of age-related macular degeneration (AMD) and its associated vision loss.


Endophthalmitis is the term used to describe severe inflammation of the tissues inside the eye. The inflammation is typically due to infection by bacteria (eg. Staphylococcus species, Streptococcus species, Gram-negative bacteria) or fungi (eg. Candida, Aspergillus).

Retina and Uveitis Service

 Physicians in the Retina & Uveitis Service have extensive experience in the treatment of diseases and conditions such as retinal detachment, diabetic retinopathy, retinitis pigmentosa, vascular occlusive disease, age-related macular degeneration, macular holes, hereditary retinal degenerations, ocular inflammation, and ocular tumors.

Retinitis Pigmentosa (RP)

Retinitis Pigmentosa (RP) refers to a group of diseases which cause a slow but progressive vision loss. In each of them there is a gradual loss of the light-sensitive retinal cells called rods and cones.

Retinopathy of Prematurity (ROP)

Retinopathy of prematurity (ROP) occurs in premature babies when abnormal blood vessels and scar tissue grow over the retina. ROP is a major cause of blindness throughout the world. 


Retinoschisis is a condition in which an area of the retina (the tissue lining the inside of the back of the eye that transmits visual signals to the optic nerve and brain) has separated into two layers.  The part of the retina that is affected by retinoschisis will have suboptimal vision. This can occur in different layers of the retina, and for different reasons. 

Ushers Syndrome

Ushers syndrome is a form of retinitis pigmentosa (RP), with associated deafness.

Uveitis (Iritis)

Uveitis means inflammation of the uvea, or the middle layer of the eye. The uvea consists of three structures: the iris, the ciliary body, and the choroid. Inflammation occurring in any of these three structures is termed "uveitis."
