Procedures

General Eye Exams

All patients are dilated for their exam. It is suggested that you have a driver. Please bring the following:

  • Glasses for both distance and near
  • Insurance information
  • A list of all your medications
  • Pertinent medical records

Fluorescein Angiography and HRA + OCT

The Heidelberg SPECTRALIS HRA + OCT is state-of-the-art technology that combines multiple new imaging techniques that allow Dr. Rankin to provide the most advanced care.

Our customized system provides six different imaging modalities: Spectral-Domain OCT, Fluorescein Angiography, ICG Angiography, Autofluorescence, Infrared Imaging and Red-Free Imaging. Our system allows multiple tests to be performed at the same sitting, saving patient’s time and allowing the specialist to diagnose and treat complex problems immediately.

Another big advantage of our system is the Dual-Beam Eye Tracking technology, which utilizes the first dual-beam scanning instrument with simultaneous confocal SLO and spectral-domain OCT imaging. This innovation combines the best high-resolution cross-sectional images of the eye with the best high-resolution images of the retinal surface, providing precise location information and multiple imaging modalities on a single platform. Again, this increases the precision of diagnostic testing and, in some cases, can reveal disorders commonly overlooked by other imaging systems.

In Office Laser Procedure

This is an ambulatory procedure performed in our office. It is recommended that someone drive you for this appointment, as dilation is required. Laser is performed for many retinal conditions including diabetes, macular degeneration, retinal holes and retinal tears. These procedures are typically pain free. Frequently you can resume all of your normal activities afterwards.

Low Vision

Many patients with retinal problems will benefit from a low vision evaluation. Low vision rehabilitation includes a variety of programs and services to help people with visual limitations to function better. Low vision services include:

  • Occupational training to assist people whose vision interferes with their work duties.
  • Magnifiers to assist in reading and other close visual tasks.
  • Mobility training for people whose vision loss interferes with their ability to get around on their own.

Retina and Diabetic Eye Center does not provide low vision services. However, we do refer patients to an appropriate facility when indicated. If your vision loss is interfering with your ability to read, drive or perform other necessary activities, ask about whether a low vision referral would be appropriate for you.

Retinal Detachment

A retinal detachment is a serious and sight-threatening event, occurring when the retina becomes separated from its underlying supportive tissue. The retina cannot function when these layers are detached, and unless it is reattached soon, permanent vision loss may result.

Signs of retinal tear or detachment include flashes of light, a group or web of floaters, wavy or watery vision, a sense that there is a veil or curtain obstructing vision, or a sudden drop in vision quality. If you experience any of these symptoms, call Dr. Rankin immediately. Early treatment is essential to preserve your vision.

Macular Degeneration

Macular degeneration, also known as age-related macular degeneration (AMD) is a common condition in older adults and the leading cause of vision loss and blindness in people over the age of 65. Macular degeneration affects the macula, the part of the retina responsible for the crisp, detailed vision needed for reading or driving. As we age, the tissue in the eye responsible for central vision slowly begins to deteriorate which can significantly affect a patient’s quality of life.

Macular Hole

A macular hole is a small break in the macula, located in the center of the eye’s light-sensitive tissue called the retina. The macula provides the sharp, central vision we need for reading, driving, and seeing fine detail.

A macular hole can cause blurred and distorted central vision. Macular holes are related to aging and usually occur in people over age 60.

Surgery is over 95% effective for the treatment of macular holes. The procedure is outpatient with local anesthesia. A vitrectomy is performed to remove the vitreous gel, and then a gas bubble is injected into the eye to help the hole close. As the eye heals, the fluid is naturally replaced. There is no non-surgical alternative.

Diabetic Eye Diseases

Patients with diabetes are at an increased risk of developing eye diseases that can lead to vision loss and blindness, such as diabetic retinopathy, cataracts and glaucoma. In fact, diabetes is actually the leading cause of blindness in the United States.

Epiretinal Membrane

An epiretinal membrane, also called a macular pucker, is a thin layer of tissue that forms over the macula, the area of the retina that gives us clear central and reading vision.

Epiretinal membranes often develop on their own as a part of the natural aging process. Particles that have drifted into the vitreous (the gel that fills the eye) settle onto the macula and begin to obscure vision. Membranes may also result from eye conditions or diseases such as retinal detachment, inflammation, injury or vascular conditions. These are called secondary epiretinal membranes, whereas spontaneously formed membranes are called idiopathic.

Some epiretinal membranes heal on their own. For those that do not, surgery is recommended. The procedure is outpatient with local anesthesia. A vitrectomy is performed to remove the vitreous gel, a saline solution fills the eye and then the membrane is lifted from the macula. There is no non-surgical alternative.

Vitreous Hemorrhage

A vitreous hemorrhage is when blood vessels grow in the gel that fills the eye and then burst. Causes of a vitreous hemorrhage can include diabetes, retinal detachment, branch retinal vein occlusion, sickle cell anemia or trauma. Symptoms, depending on the severity can include blurred vision, light flashes, floaters that may be dark or red and/or loss of vision.

Only your eye doctor can diagnose or treat a vitreous hemorrhage. If you are having signs of blood in your eyes, seek the help of Dr. Rankin right away.
