Gurugram: The survey to assess the prevalence of cases of blindness and causes in the city, which will be carried out next week by AIIMS and the Ministry of Health, is one type as a bias error in vision will be borne for the first time the state, officials from the Institute said.
According to Professor Praveen Vashist, responsible for the spirit of the community in AIIMS, they decided to conduct a pilot study to assess the causes of eye defects since 80% of cases of blindness in India were caused by cataracts and refractive errors.
At the 73th Health Meeting was held recently, the World Health Organization (WHO) came out with a global indicator to achieve universal eye health care.
It includes cataract surgical coverage and refractive errors as two indicators.
While cataracts develop when the lens of the eye becomes cloudy, requires surgery to replace it with an artificial lens, a bias error occurs when the eye shape makes someone not focus properly, resulting in opaque vision.
According to WHO 2010 data, India accounts for 20% of the burden of global blindness.
It is not clear where India stands when it comes to biased errors in vision.
The survey has been designed to get the correct picture, said Vashist, the main investigator for this research.
“This study aims to collect data to be analyzed to understand eye defects.
This will help determine the solution for the long term,” he added.
Asked how this survey is different from other surveys, Vashist said: “I am responsible for the National Blindness and Vision Decairment survey conducted between 2015 and 2019.
There are several lacunes in practice, such as only people over 50 years that are included and the bias errors are not closed .
For the first time, this survey will cover bias errors and also include a population of a district above five years.
In this survey, we try to include all parts of the population.
How many people can get glasses for biased errors will also be borne.
“Surveys will be Focus on determining the burden of blindness, causes, and factors related to visual disorders.
The impact of visual disturbances due to refractive errors that are not corrected in younger age groups is very large, Vashist said.
The team will collect data about how many people have access to glasses and also study presbyopic cases (gradual losses of eye ability to focus on the nearest object).
If it works, it can be a pioneer for all such surveys in the future, he said.
“We can train people about how to conduct surveys about cataract surgery and a problem of refractive errors and conduct similar surveys throughout India,” he added.
