How can we Diagnose Diabetic Retinopathy?
Eye examination with ophthalmoscopy, visual acuity, tonometry, fundus fluorescein angiography and retinal photography aid in diagnosing diabetic retinopathy.
Diabetic retinopathy is diagnosed with the help of the following tests-
Eye examination - After dilating the pupil, the ophthalmologist checks the retina with an instrument called an ophthalmoscope for -
Leaking blood vessels
Macular edema (swelling of the central part of the retina, the area that is responsible for central vision)
Pale, fatty deposits (called lipids on the retina) which signal leaking blood vessels
Damaged optic nerve tissue
Changes in the blood vessels in the eyes
Visual acuity - The ophthalmologist may also test how well the patient can see at various distances.
Tonometry- The ophthalmologist may also measure the pressure in the eye, with the help of a tonometer to check for signs of glaucoma, which also commonly occurs in people with diabetes.
Fundus Fluorescein angiography (FFA) - This is an imaging technique which gives a clear picture about the eye vasculature and allows the eye care professional to identify any leaking blood vessels.
Retinal photography: Retinal photography is a procedure where a picture of the retina is taken and evaluated for abnormalities.
