چکیده
The Ophthalmoscope was developed by Von Helmotz. He published his work in1851 [1]. The direct ophthalmoscope has since being further developed and re-engineered. However the field of view is limited to about 5 degrees. Most physicians are reluctant to use it and patient education was not possible with it as only the doctor sees the retina. In 1945, Charles Sheepens developed the indirect ophthalmoscope [2]. This provided a wider field of view and helped in the examination of the peripheral retina. However it has a difficult learning curve and too bulky for the general physician. Subsequently, mirrors were attached to the indirect ophthalmoscope to provide a teaching platform. Still patient education was limited to retinal drawings and sketches made by the doctor. Many years later, video camera attachment to the indirect ophthalmoscope was developed. This improved teaching and patient’s education. The equipment came at a price not affordable to physicians in the poor resource countries. Fundus camera was later developed. It was bulky and the cost was too high for physicians in the developing countries. Attempts were made to develop portable fundus camera. The available ones are still expensive for our environment in Sub Sahara Africa. Recently portable devices such as the iexaminer in which the iphone was attached to the panfundoscope were Mobile Phones for Fundus Photography in Ibadan, Sub Sahara Africa
