The retina is a multi-layered membrane that lies at the back of the eyeball. Less than half a millimeter thick and about 22 millimeters in diameter, it contains five layers and over 150 million light sensitive cells. The retina is vital to the sense of sight, processing signals from light that enters the eyeball through the retina and then transmitting these signals to the optic nerve.
Any damage to the retina, such as tearing or detachment, can result in seriously compromised vision. Some diseases to the retina are progressive, and can be more easily treated or dealt with if they’re diagnosed early. Among these conditions are:
- Pre-retinal membranes
- Macular holes
- Damage to the optic nerve
- Diabetic retinopathy
- Cystoid macular edema
Evaluating the condition of the retina can be difficult, since its position at the back of the eyeball means it can only be viewed through the pupil. At Cherry Creek Eye Physicians and Surgeons, new technologies for retinal diagnosis make this easier. Optical Coherence Tomography (OCT) is a new, innovative procedure that allows ophthalmologists to view the retina in almost microscopic detail.
The Cirrus HD-OCT Instrument takes cross-sectional images that produce a highly accurate, three-dimensional representation of the retina. By examining these images, Dr. Lewis can determine if any irregularities have developed in the layered tissue of the retina, and if these irregularities might indicate a disorder that needs to be treated.
This and other high technology diagnostic tools and treatments allow Dr. Lewis to offer a variety of state-of-the-art options for his patients. The Cirrus HD-OCT allows Dr. Lewis to diagnose retinal problems very early, and to offer innovative treatments to help protect your vision.
