The Nigerian Air Force (NAF) has commenced free glaucoma screening and sensitization campaign among personnel and their dependants nationwide. The aim is to provide early detection and treatment of the ailment while enlightening members of the Air Force family and people within host communities around NAF units about the danger of glaucoma which is becoming rampant and increasingly undetected among Nigerians. The campaign, comprising free medical screening and awareness lecture, was started-off yesterday at NAF Base Makurdi to coincide with the World Glaucoma Week which is a joint initiative between the World Glaucoma Association and World Glaucoma Patient Association. A total of 317 persons benefitted from the free eye test. The exercise would be conducted in all NAF units across the country.
