Situation in Brief

With a small population and shortage of doctors, Tonga relies on ophthalmic nurses and mid-Tongalevel personnel to provide the majority of services. The country has a strong diabetic eye disease programme. Cataract patients wait for visiting teams, who are often supported by NGOs. Ophthalmic nurses run eye clinics on Tongatapu and Vava’u. A medical assistant, trained at Pacific Eye Institute in diagnosis and laser treatment of diabetic retinopathy, runs the diabetic eye programme. WHO has noted Tonga’s steep increase in obesity, diabetes and cardiovascular disease to be a worry and the most important health problem for Tonga. Specialist nurses provide services from the diabetic clinic on Tongatapu. Trained medical assistants provide laser treatment and intravitreal medical therapy for diabetic retinopathy. A national plan for eye health has reportedly been endorsed.Tonga, WPR
