The retina is a multi-layered sensory tissue that lines the back of the eye and connects the visual images that you see to the brain via the optic nerve. The retina has millions of photoreceptors that capture light rays and convert them into electrical impulses. These impulses actually travel along the optic nerve to the brain where they are turned into images. Any type of disruption in the traveling of these images to the brain results in vision loss or distorted vision. The central part of the retina called the “macula” is the most sensitive aspect. If this macula is affected by disease seeing can become very difficult. The macula is responsible for your accuracy vision, allowing you to read or recognize a person.
Tennessee Retina Eye Doctors
Donny Reeves, MD is a board-certified Tennessee ophthalmologist with experience in diagnosing and treating eye diseases of the retina. Paramount to his retina eye work is the emphasis on regular eye exams if you are suffering from retina problems or are diabetic. Retina eye exams can save vision and prevent blindness.
Why are Retina Eye Exams Important?
The retina is an extension of the brain. Much like the brain tissue, the retina cannot regenerate. Diseases of the vitreous and retina can cause permanent blindness, therefore getting regular eye exams is critical for long term eye care. Our Tennessee retina eye doctor will spend a lot of time looking through your pupil at the vitreous, retina, and other structures located inside the back portion of the eye. In order to adequately see the retina, we will need to dilate eyes prior to a retinal examination. First, the pupils are dilated using eye drops (this allows a complete retinal examination). The retina is examined using various instruments that throw a strong light into the eye. Most patients do not experience any discomfort except for some glare. Early and adequate treatment can stop further damage to the retina and result in a better outcome. Retinal eye exams allow early detection and treatment of retinal disorders.
Retina Conditions & Diseases
Retinal Vein and Artery Occlusion
Age-Related Macular Degeneration
Ocular Malignancies – Retinoblastoma, Choroidal Melanoma
The Tennessee retina eye doctors at Reeves Eye Institute treat many serious disorders affecting the retina and associated structures. If you would like to more information regarding retina eye conditions please feel free to visit our web pages on diabetic eye care and retinal diseases.
The retina is one of the most important structures of our visual system. The retina is a light-sensitive tissue lining the inner surface of the back of the eye.
About The Retina
RetinaThe retina serves a similar function to the film in a camera. The optics of the eye create an image of the visual world on the retina. Light striking the retina initiates a cascade of chemical and electrical events that trigger nerve impulses. The photoreceptor cells, the rods and cones, are involved in this complex process. The retinal impulses are then carried through the optic nerve to the brain.
There are many diseases of the retina, which can affect eyesight. Some common diseases such as diabetes and hypertension can directly affect the retina and cause poor functioning of the retinal cells. Other common retinal disease processes include macular degeneration and retinal detachments. All of these retinal diseases can result in a significant loss of vision.

Keratoconus is a condition of the eye, which causes the cornea to thin out, resulting in a protrusion of the cornea. Due to the protrusion, the front of the eye appears cone-shaped, causing the light passing through to be distorted. If the cornea is not smooth, the images passing through to the retina will not appear properly. These distorted images can cause halos, starburst surrounding lights, blurred vision, multiple images, and ghosting. Keratoconus is a progressive condition that often develops in the teens and into early adulthood, gradually worsening over time.
Corneal dystrophy is a rare genetic eye condition in which one or more parts of the clear outer layer of the eye (the cornea) lose their normal clarity as a result of a buildup of cloudy material. The general term corneal dystrophy refers to a group of corneal diseases. There are many types of corneal dystrophies, and they are distinguished by the specific part or parts of the cornea affected.
Fuchs’ dystrophy is one of the more common corneal dystrophies. Fuchs’ dystrophy is an inherited condition that affects the delicate inner layer (endothelium) of the cornea. The endothelium functions as a pump mechanism, constantly removing fluids from the cornea to maintain its clarity. Tennessee Fuchs Dystrophy patients gradually lose these endothelial cells as the dystrophy progresses. Once lost, the endothelial cells do not grow back, but instead spread out to the fill empty spaces. The pump system becomes less efficient, causing corneal clouding, swelling and eventually, reduced vision.
