ophthalmoscope

An ophthalmoscope is a medical instrument used by eye doctors (optometrists or ophthalmologists) to examine the interior structures of the eye, especially the retina. It allows them to look through the pupil with a light source and special lenses, revealing details like blood vessels, the optic nerve, and other tissues. This helps in diagnosing eye conditions such as diabetic retinopathy, glaucoma, or retinal detachment. The device can be handheld or part of a larger system, enabling a detailed view of the back of the eye to assess overall eye health.
