G. Vasudharini (left) and her three sisters suffer from corneal
dystrophy, a condition arising from a birth defect. Following a second
corneal transplant, doctors are hopeful she will recover her sight.
******************************************************
G. Vasudharini (17) should have started college this
year but has just been admitted to class VIII. She lost five years of
schooling to preventable blindness.
Vasudharini’s
parents are first cousins. The couple have four daughters and all of
them suffer from corneal dystrophy, a condition which may be
asymptomatic initially, but might require treatment including surgery at
a later date.
Among the sisters, Vasudharini
suffered the most. She was brought to Rajan Eye Care Hospital when she
was 10 and underwent a corneal transplant. But her parents did not
return for a follow-up.
“She couldn’t keep her eyes
open. She was blind with photophobia and had to drop out of school. She
could not even watch TV,” said Sujatha Mohan, who realised the surgery
to correct Vasudharini’s vision had proved a waste. After her father’s
death last year, Vasudharini’s maternal grandfather M. Shanmugam brought
her to the hospital for consultation.
Vasudharini
underwent another transplant in her left eye. Four months ago, Dr.
Sujatha performed an anterior lamellar corneal transplant (involving the
four damaged layers of the cornea). On Wednesday, Vasudharini had a
check-up.
As she is young, she would recover her
sight, the doctor said. She will also be given treatment to correct the
squint she has developed from favouring her good eye.
Vasudharini’s
10-year-old sister has also undergone a transplant but her older
sisters suffer from a milder form of the condition.

Rajan, medical director of the hospital, said 60 per cent of corneal
blindness due to birth defects occurs in children below the age of 15
years. Of this, anywhere between 25 and 50 per cent of children are at
risk for birth defects due to consanguinity.
“If you
can eradicate it effectively to a large extent we can prevent
blindness. In India, close to one million children below the age of 15
are blind,” he added.
The fortnight between August 25 and September 8 is observed as National Eye Donation fortnight.
