BENGALURU: While the variety of eye donors has gone up through the years, the variety of corneas utilized for transplants is way decrease.
According to knowledge from the directorate of well being and household welfare companies, solely 40% of the donated eyes have been transplanted in Karnataka in 2016-17. “Of the 3,527 eyes donated, 1,391 were used for corneal transplants, while the remaining were utilized for research and educational purposes,” stated Omprakash Patel, joint-director (ophthalmology), DHFWS.
The state of affairs will not be very completely different in different components of the nation. Less than 50% of the eyes donated beneath the National Programme for Control of Blindness (NPCB) by the ministry of well being and household welfare are used for corneal transplants, minister of state Anupriya Patel had instructed the Lok Sabha in a written reply in April this yr.
The low charge could be attributed to the truth that not all donated corneas are discovered appropriate for transplants. “There is a stipulated time period during which the organ must be recovered from the deceased. Otherwise, it can’t be used. Moreover, if the donor is very old, or has died due to a highly infectious disease, the donated cornea can’t be utilized. Also, if the cornea is handled by unqualified people, it can get damaged,” stated MK Krishna, chairperson, south zone, Eye Bank Association of India.
According to NPCB, Karnataka has been seeing Three,500-Four,000 eye donations yearly since 2012. However, the distribution will not be uniform throughout the state. “According to our records, 3,515 eyes were donated in 2016-17, but over 75% of them were from Bengaluru alone. There’s a need to create awareness and build infrastructure in other districts as well,” added Krishna.
Dr Rajkumar Eye Bank at Narayana Nethralaya accounts for the very best variety of eye donations within the state — practically 1,700. The ready interval is about 2-Three months, with 80-100 folks ready for a transplant at any given level of time.
Transplants largely profit these with corneal blindness. “There are over 10 lakh people suffering from corneal blindness in the country, and only 50,000 eye donations, of which only 40%-50% are utilized. The number of donations should be 1-2 lakh annually,” stated Dr Ok Bhujang Shetty, chairman, Narayana Nethralaya.
However, there isn’t a knowledge on the precise variety of such sufferers within the state. To acertain the quantity, a pilot survey was carried out in three districts in September. “We detected around 150-200 cases each in Davanagere, Vijayapura and Chamarajnagar, and hope to extend the survey to the whole state to get a clearer picture,” Patel stated.
Used in different procedures
“Once we receive the eyes, we grade them according to their quality. Only corneas of the best quality (the 40%), can be used for optical keratoplasty, ie to give sight, while the remaining can be used for therapeutic keratoplasty. The latter is performed in cases of perforation/ulcer, when the donated cornea can save the eye,” stated Dr Shetty.
“In many cases we see in adults, corneal infections are caused due to improper usage of contact lenses. In children, the causes can vary —firecrackers, pencil wounds and bow-and-arrow injuries. While we do offer therapeutic keratoplasty, we don’t get too many cases,” stated Dr Raghu Nagaraju, senior marketing consultant, Dr Agarwal’s Eye Hospital.
