Low-cost components make portable fundus cameras a reality

摘要

To monitor eye diseases such as increased pressure in the eye (glaucoma) and document any potential of damage to the retina from diabetes (diabetic retinopathy) such as retinal neovascularization, hemorrhage, and macular edema, it is necessary to image the retina. This is performed by ophthalmologists using fundus cameras-specialized optical instruments with attached cameras to view between 30-50° of the retinal area.
