Retinal photography, demonstrated in this image, is the high-tech, non-invasive test, which cannot possibly be omitted in a comprehensive examination of a pair of eyes. To get a high-resolution digital image of the retina, the light-sensitive tissue in the back of the eye, the camera is then internally focused on the chin of the patient and the camera internal focus is made. It is a vital process as it documents the health of the optic nerve, blood vessels, and macula and this standard is a permanent base that is subsequently used as a reference point. It is critical in the early diagnosis and treatment of the sight-threatening diseases such as glaucoma, macular degeneration and diabetic retinopathy, which mostly portrays the symptoms before it ever occurs. The picture is a representation of how the contemporary optometry employs the accurate and painless technology to protect and avoid the loss of long-term vision as well as to give a picture of long-term health system.
