What Are Retinal Diseases?

Retinal diseases encompass a range of illnesses that affect the retina of the eye — a thin layer of tissue at the back of the eye that converts light into neural signals that the brain can then form into images.

Age, illness, and injury can all impact this delicate tissue and cause a variety of complications, including partial or complete loss of vision. Other symptoms include floaters, blurred vision, flashes of light, and shadows in the peripheral vision. It is important to see a retina consultants at the earliest signs of these symptoms in order to address the root cause and mitigate long-term vision loss.

Scroll down to learn about some of the most common retinal illnesses, including retinal detachment, macular degeneration, and diabetic retinopathy, and follow the links to the left for more in-depth information.

Macular Degeneration

There are two types of Age-Related Macular Degeneration (AMD), a disorder common in people over 50 years of age. Dry AMD, the more common type, refers to deposits under the retina that can lead to deterioration of vision cells over long periods of time. Wet AMD refers to the spontaneous growth of abnormal blood vessels under the retina that cause leakage of fluid and/or hemorrhage that, left untreated, results in central vision loss

Diabetic Retinopathy

Diabetic retinopathy refers to microvascular damage to the blood vessels in the retina that occurs over time as a result of elevated blood sugar levels. In early stages, a patient may not have any visual symptoms, but as the disease progresses, floaters, blurred vision, and complete loss of vision can occur. Controlling the diabetes and timely diagnosis and  intervention by a retina specialist can help to preserve and possibly improve vision.

Branch Retinal Vein Occlusion

Branch Retinal Vein Occlusion (BRVO) is a blockage of blood flow in a branch of the central retinal vein, which is responsible for bringing  blood from the retina back to the heart. Symptoms include floaters, blurred vision, and loss of peripheral vision.

Central Retinal Vein Occlusion

Central Retinal Vein Occlusion (CRVO) is a blockage of the central retinal vein, which is often more severe than a BRVO. This disruption in blood flow often results in swelling of the optic nerve through which the central retinal vein normally exits the eye as well as leakage of blood and fluid into the retina. Symptoms of CRVO include sudden, painless loss of vision in the affected eye, which can worsen rapidly in a matter of  hours or days. 

Central Serous Chorioretinopathy

Central Serous Chorioretinopathy (CSCR) is a disorder that  most commonly affects young- to middle-aged adults in which fluid painlessly accumulates under the retina. Stress and steroid medications are strongly implicated as risk factors for CSCR. Symptoms include distortion, blurring, and/or a blind or gray spot in the central vision. Acute CSCR often resolves on its own over 2-4 months, but chronic or recurrent CSCR may require treatment in order to avoid gradual deterioration of vision. .

Cystoid Macular Edema

Cystoid Macular Edema (CME) refers to cyst-like pockets of fluid that arise in the macula, the center of the retina. CME is a painless disorder that can lead to blurred and distorted central vision. There are many potential causes of CME and a variety of potential treatment options. 

Macular Hole

A macular hole is a defect  that forms in the macula, which results in distortion, blurring, and/or blind spots in central vision. If left untreated, the hole will expand in size over time, leading to further deterioration of central vision. Prompt diagnosis  and surgical treatment will result in better final visual prognosis. 

Macular Pucker

A macular pucker occurs when scar tissue forms on the surface of the macula and creates traction on the delicate nerve tissue, which results inturn distortion and/or blurring of central vision. This condition may be slowly progressive, but surgery is effective and helpful, particularly if patients are symptomatic. 

Retinal Artery Occlusion

The central retinal artery and its branches are responsible for delivering blood and oxygen to the retina.. A blockage will result in a sudden painless loss of vision  and requires immediate medical attention to identify and treat associated medical conditions.

Retinal Detachment

A retinal detachment is when part of the retinal tissue detaches from the blood vessels supplying it with blood and oxygen. Floaters, flashes of light, and either visual shadows or a curtain are common symptoms. Without treatment, the consequence is total vision loss. Even when repaired surgically there is often some residual impairment. The prognosis is best when detected early on after onset of visual symptoms.

Retinal Tears (Flashers & Floaters)

A retinal tear can arise from trauma or due to posterior vitreous detachment, which involves the age-related separation of the gel in the eye from the retina.  Laser treatment is a highly effective way to seal a tear, reducing the odds of progression to retinal detachment.
