Retinal Detachment - How It Occurs

At Retina Associates in Tucson, Arizona, Dr. Cameron Javid and his associates treat related ophthalmological conditions, such as retinal detachment. In doing so, the professionals at Retina Associates draw on an in-depth knowledge of retinal structure and the processes that contribute to this condition.

In the human eye, the retina consists of a layer of tissue responsible for receiving and processing visual stimuli. This light-sensitive tissue receives light rays after they pass through the cornea, the pupil, and the lens. These structures focus the light on the retina, which transforms that light into neural messages that travel through the optic nerve to the brain.

To reach the retina, rays of light must pass through a clear gel known as the vitreous. This substance has a tendency to shrink as an individual ages, and this shrinking can cause it to tug on the retina. This most often occurs without any symptoms or damage, but it is possible for such tugging to cause the upper layers of the retina to separate from the basement membrane underneath it.

When the retina detaches, it often causes the sudden appearance of floating specks or light flashes in the field of vision, or darkness. These symptoms are signs of an emergent condition and should prompt immediate medical attention, as vision loss related to retinal detachment may become permanent if not treated.
