Vision plays a very important part in the early development of a child. Impaired vision at birth will cause serious delay in development and is likely to lead to learning disabilities, particularly when associated with other problems, such as congenital deafness.
Congenital blindness due to Retinitis Pigmentosa (RP) took away Jyotindra Mehta’s power of sight at a very young age. Emigration to the US on scholarship, coupled with a readiness to take up any challenge, resulted in Jyotindra’s quick success there.

Congenital blindness due to Retinitis Pigmentosa (RP) took away thir eye sight at very early age.
About 9 in 10 children who are considered blind from birth have some vision, even though it may be only recognition of light and dark or shapes.
There are several causes including microphthalmos, cataracts, bilateral pseudogliomatous retinal detachments, and phthisis bulbi. OPPG is usually not suspected until fractures occur, frequently after seemingly minor trauma.
In the developed world, half of all cases of congenital blindness run in families and therefore may be due to a genetic disorder. another important cause is congenital infection such as the protozoal infection toxoplasmosis and the viral infection rubella. These infections are transmitted from the mother to the developing fetus during pregnancy and may lead to impaired vision in the newborn baby. congenital rubella is now rare in the developed world due to routine immunization. The baby’s eyes may also be affected by cataracts, in which the lenses are opaque, or glaucoma, in which the optic nerve is damaged due to increased pressure in the eyes. Congenital blindness may also be caused by damage to the brain as a result of lack of oxygen during birth.
Parents usually become aware that their have a vision problem within a few weeks. he or she may less responsive than other babies, lying quietly to make the most of his or her hearing. parents may also notice that their baby:
Â· Is unable to fix his or her eyes on a close object.
Â· Has random eye movements.
Â· Does not smile by the age of 6 weeks.
Â· Has abnormally large, cloudy eyes if glaucoma is present.
Parents may find it difficult to bond with a quiet baby who does not smile.
If congenital blindness is not suspected by a babyâ€™s parents, it will probably be picked up during a routine examination in infancy. A child suspected of having an impaired vision will be referred to a specialist for an examination and tests. His or her hearing will also be tested because, if the child is severely visually impaired, he or she will rely more on hearing.
It is possible to improve vision in only a smaller number of babies, such as those with cataracts or glaucoma. Early treatment of these conditions is important. cataracts are usually removed surgically within the first month of life. glaucoma may also be treated surgically to allow fluid to drain from the eye.
If vision cannot be improve, much can be done to help a child make maximum use of other senses or what little vision he or she has. if your child is diagnosed as blind, a team of specialist, including a teacher for the blind, will be able to give you and your child support and care. You will also be given advice on how to stimulate your child, by using your speech, sounds, and touch and how to adapt your home so that your child can explore it safely and develop self-confidence. Some children will require special schooling to learn braille, a system of raised dots that allows blind people to read.
Genetics counseling is available for parents of an affected child who wish to have more children or for prospective parents who are blind.

Children treated for cataracts or glaucoma will probably still have impaired vision but often have enough sight to perform most activities unaided. Many blind or visually impaired children with no other disabilities go on to have successful personal and professional lives.
