The eye and its functions encompass a variety of spheres that can be simply explained as below;
The eye and Vision
One is able to see once light rays enter the eyes through the cornea. The light rays are then focused on the retina where it gets absorbed into the photoreceptor cells.
The Photoreceptors will then convert the light into electrochemical signals which are sent via the optic nerve to the brain.
The brain will then interpret the information and electrochemical signals are converted into light impulses and fuse both images from the eyes
Understanding the human eye
It is the innermost photosensitive layer of the eye, which connects to the brain via the optic nerve.
Just as the Cornea is important, so is the retina and it can be affected by various issues (retinal disease) which may render vision less effective
Common Diseases that affect the Retina include;
- Diabetes mellitus
- Hereditary degeneration
- Infectious diseases
- Age-related Macular degeneration
- Congenital degeneration
Signs and Symptoms of Retinal Diseases
- Flashes of light
- Gradual decrease in Vision
- Night Blindness
In case a patient experiences any of the above signs and symptoms, he or she must consult a retinologist for an evaluation. Patients who fall under the following categories must consider meeting a retinologist as soon as possible;
- Diabetic patients
- Individuals over the age of 43 years
- Hypertensive patients
Retina treatments require immediate treatment to prevent loss of vision. A Vitreoretina Surgery in India is one of the possible treatments when it comes to retinal diseases and related issues
