PESHAWAR The experts have said that 2.5 per cent population of Pakistan is suffering from blindness and out of the 80 per cent can be prevented or treated through public awareness campaigns. An estimated 37 million of the worlds 6 billion population suffered from blindness. Unfortunately 80 per cent of these blind live in the developing countries where resources are limited, said ophthalmologist Prof Shad Muhammad. Speaking at a seminar organised by the Pakistan Islamic Medical Association in collaboration with the Prime Foundation to mark the World Sight Day at the Peshawar Medical College on Thursday, Prof Shad Mohammad, who is Director Academics and Admissions and Dean Faculty of Nursing and Allied Health Sciences Khyber Medical University, said that cataract was responsible for 39.1 percent of total blindness globally followed by refractive errors with female 64 percent and male 36 percent. Citing WHOs study, he said that Pakistan has one ophthalmologist for a population of 600,000 in 1980. Most ophthalmologists were located in urban centres while 80 per cent of the population was in rural area, he said. At that time the eye care services were provided mainly by tertiary hospitals, secondary hospital, mission hospitals and some cottage hospitals and were out of reach of majority of rural population, he said.
