What is the function of the ophthalmoscope?

The ophthalmoscope is an essential instrument used in medical examinations primarily for checking the retina and other structures at the back of the eye. Its main function involves allowing healthcare professionals to visualize the interior of the eye, particularly the retina, optic disc, and blood vessels. This examination is critical for diagnosing various conditions such as diabetic retinopathy, hypertension, and other ocular diseases that can affect vision and overall health. By enabling a detailed view of the retinal structures, the ophthalmoscope plays a crucial role in comprehensive eye care and general health assessments.
