Visual Inspection of Tissues with Certain Endoscopes and Other Optical Devices
Published in Robert B. Northrop, Non-Invasive Instrumentation and Measurement in Medical Diagnosis, 2017
The ophthalmoscope is a simple optical instrument that permits the NI visualization of the front surface of the eye's retina (also known as the fundus), showing blood vessels, general color, surface smoothness, any tears or detachments, and the condition of the macula, etc. These features are normally viewed by the eye of the examining ophthalmologist, and in modern instruments can also be photographed or recorded as digital color images.

Ophthalmoscopy is a device used to examine the inside part of the eye and can be performed on a dilated or non-dilated eye. The color, shape, and overall health of the optic nerve are important signs in glaucoma diagnosis that can be checked directly or by using a digital camera to photograph the optic nerve.

The eye fundus examination (also known as fundoscopy and ophthalmoscopy), is a routine examination of the back part of the eye where the retina, optic disc, choroid and blood vessels can be observed (Clark and Kruse 1990). Examination of the fundus can provide information regarding any problems, damage and diseases of the eye which can be associated with various conditions including head injuries, diabetes mellitus, increased intracranial pressure and glaucoma (Clark and Kruse 1990). This is of importance considering there are approximately 119 million people over 40 years old in the United States alone that are at risk of developing eye-related diseases (Clarkson 2003). The examination can be conducted using an indirect ophthalmology approach (where the medical professional holds a lens over the patient’s head and looks directly at the fundus), or with a direct ophthalmology (DO) approach where an ophthalmoscope (or fundoscope) allows observing the back of the eye by adjusting the lens, lights and filters associated with the opthalmascope.
A Comprehensive Survey on the Detection of Diabetic Retinopathy

Some eye specialists use direct ophthalmoscopy, indirect ophthalmoscopy and slit-lamp bio-microscopy to examine the eyes. The direct ophthalmoscope is rarely used by non-ophthalmologists because it is less effective in diagnosing any abnormalities. Eye experts can evaluate the large field of the retina using indirect ophthalmoscopy and slit-lamp bio-microscopy.
