Quizplus · Accepted Answer

The red reflex is elicited with an ophthalmoscope and represents reflection of the ophthalmoscopic light through the lens onto the vascular retina.The absence of a red reflex strongly indicates a lens opacity that does not allow light to penetrate through to the retina.The other answers are not related to a lens opacity.Increased intraocular pressure is measured by tonometry and could indicate glaucoma.Decreased central vision is measured by a Snellen chart and a Jaeger card and indicates decreased visual acuity.Positive corneal staining with topical dye could indicate corneal abrasion.
