20/20 is considered to be normal vision for a person while a vision at 20/70 or lower than that is considered as Low Vision. A person who is diagnosed with a low vision is considered to be visually impaired as even the use of eye glasses, lenses, surgery or even medication won’t be able to fully correct the condition.
A patient may need other devices apart from eye glasses to view properly. At Aakash Healthcare Super Speciality Hospital, we have latest equipment and magnifying instruments which can be used by patients with low vision.
Causes of Low Vision
Low vision can also lead to complete blindness. It does not develop instantly, usually it occur due to other persistent problems. Therefore, it is always advisable to visit your eye-specialist regularly if you are suffering from following conditions:
- Diabetic Retinopathy: Diabetic retinopathy develops in patients with type I or type II diabetes. The increased sugar level in the blood results in blockage in blood vessels of the eyes. These blockages may lead to development of abnormal vessels which, sometimes leaks blood or fluid into the eye thereby damaging the retina. If not treated, this condition may result in low vision or complete blindness.
- Glaucoma: Pressure on the optic nerve may result in deterioration in vision. Glaucoma usually develops in elderly patients and can lead to low vision if not treated on time. There is both medicinal treatment and surgical treatment available for glaucoma.
- Eye Cataract: Development of eye cataract is very common and is easily treatable through laser surgery. A cataract is a clouding which develops on the eye lens resulting in vision problem. The doctors remove the clouding in a minor surgery replacing it with an intraocular lens which acts like a natural one.
- Retinopathy of Prematurity: This condition may develop in infants. Sometimes, high levels of oxygen in the incubators may affect the retina resulting slow deterioration in vision.
- Macular Degeneration: This condition refers to gradual degeneration of retina due to several factors.
