Retinal Problems are eye issues that relate to problems with the retina. The retina is a layer of tissue present at the back of the eye that is responsible for sensing light and sending images to the brain. Common Retinal Problems are diabetic eye disease, retinal detachment, retinoblastoma, macular pucker, floaters and macular degeneration. Symptoms of Retinal Problems vary with the specific disorder. Common symptoms are blurry vision, floaters and flashes of light, darkening of vision and eye fatigue.
HOW IS RETINAL PROBLEMS DIAGNOSED?
Ophthalmologist conducts a thorough eye exam and looks for abnormalities anywhere in the eye. The following tests may be done to determine the location and extent of the disease:
Amsler grid test.
Optical coherence tomography (OCT).
Indocyanine green angiography
CT and MRI.
HOW IS RETINAL PROBLEMS TREATED?
Surgery is the most common treatment for retinal problems.Focal laser photocoagulation can repair a retinal tear or hole. Scatter laser photocoagulation is used to shrink abnormal new blood vessels which are bleeding or threatening to bleed into the vitreous.Cryopexy in which a freezing probe to the external wall of the eye to treat a retinal tear.
DID YOU KNOW?
Genetically dominant eye diseases are gain-of-function mutations and cannot be corrected by adding a corrective gene. The defective gene first must be inactivated. Progress has been made in this arena by using a mutation-specific, ribozyme-based therapeutic strategy with longstanding rescue in two different lines of transgenic rats, each with its own rhodopsin mutation. Two classes, hammerhead and hairpin ribozymes, were found to be effective.
