A)Cataracts are diagnosed on the basis of the patient's history and eye examination. The Snellen and Rosenbaum charts are used. A dilated eye exam with either an ophthalmoscope or slit-lamp examination provides a magnified view of the structures of the eye. Ophthalmoscope examination confirms the diagnosis by identifying the location and extent of a cataract. Revealing a dark area is something that would happen only as the cataract matures. Visually inspecting the optic fundus and using tonometry to measure intraocular pressure are diagnostic tests for glaucoma.
