What is the retina and what does it do?

The retina is a thin layer of tissue that lines the back of the eye on the inside. The center of the retina (called the macula) is located near the optic nerve, and the peripheral retina extends along the inside of the eye. The purpose of the retina is to receive light that converts into signals and then these signals are sent to the brain for visual recognition.

Signs of Retinal Damage

Any of these symptoms may indicate that you have retinal damage, but only a trained eye doctor can diagnose:

 

  • Flashes of lights

  • Sudden increase of floaters

  • Shadow or curtain in vision

  • Gradually reduced side (peripheral) vision

  • New grey spots, strings, or spider webs

 

Treatments for Retina Vitreous Problems

Our retinal specialist can perform some procedures and treatments in our offices. Other procedures may require an outpatient surgery hospital.

There are a number of surgical options that your surgeon may consider:

Intravitreal Injections

During this procedure, your doctor injects medicine into the vitreous, which is the central space inside the eye. Injections are used to treat several retinal conditions including macular degeneration, macular edema and retinal vein occlusions.

Laser Treatment

Non-invasive laser treatment is used to treat several conditions including diabetic retinopathy, to limit scarring from wet macular degeneration, or treat retinal tears to prevent retinal detachments. Laser treatment is commonly performed in the office.

Cryotherapy

Cryotherapy may be used to treat retinal detachments and tears. Cryotherapy freezes and seals abnormal “leaky” blood vessels or retinal tears.

Scleral Buckling

The Scleral Buckling procedure is commonly used to treat retinal detachment and is completed in a hospital setting. A scleral buckle is a placed around the eye and helps to hold the retina in place.

Pneumatic Retinopexy

Pneumatic Retinopexy is used to repair a retinal tear and detachment. During this procedure, a gas bubble is injected into the vitreous cavity which helps seal the tear and reattach the retina.

Vitrectomy

Vitrectomy is commonly performed for vitreous hemorrhage, diabetic retinopathy, macular hole, epiretinal membrane, or retinal detachments. During this procedure, which is performed in the operating room, your doctor uses microsurgical instruments to remove the vitreous gel and treat the retinal problem that is affecting vision.

Possible Complications

As with any surgical procedure, there are risks associated with retina treatment. Each eye in each situation is unique, and you should discuss the various options available to you to determine which of these options would be ideal for your situation.

Any and all surgical procedures should be taken seriously. Even after the doctor has answered any questions you might have, you should take some time and think it over before committing to surgery.
