The indirect ophthalmoscope is a medical device used by ophthalmologists to examine the inside of the eye. It consists of a light source, a headband, and a handheld lens.
The device works by directing a beam of light into the patient's eye, which then reflects back through the lens and into the ophthalmologist's eye. This allows for a magnified and stereoscopic view of the retina and other structures at the back of the eye.
The indirect ophthalmoscope is particularly useful for evaluating the peripheral retina and diagnosing conditions such as retinal tears, detachments, and tumors. It also aids in the assessment of the optic nerve and blood vessels within the eye.
By adjusting the position and focus of the lens, the ophthalmologist can explore different areas of the retina and obtain a comprehensive view. The device provides a wider field of view compared to direct ophthalmoscopy, allowing for a more detailed examination.
