Ophthalmoscopy, also called funduscopy, is a test that allows a health professional to see inside the fundus of the eye and other structures using an ophthalmoscope (or funduscope). It is done as part of an eye examination and may be done as part of a routine physical examination .
Scanning laser ophthalmoscopy developed as a method to view a distinct layer of the living eye at the microscopic level. The use of confocal methods to diminish extra light by focusing detected light through a small pinhole made possible the imaging of individual layers of the retina with greater distinction than ever before.

Also ophthalmoscopy and gonioscopy examinations can also be performed through the slit lamp when combined with special lenses. These exams help to see the specific structures, such as the retina and optic nerve, which is at the back of the eye, and the drainage system that controls the intraocular pressure, which is in the angle formed between ...
Once the pupil is dilated, examiners use ophthalmoscopy to view the eye's interior, which makes it easier to assess the retina, optic nerve head, blood vessels, and other important features. DFE has been found to be a more effective method for evaluating eye health when compared to non-dilated examination, [ 2 ] [ 3 ] and is the best method of ...
System: Eye and visual system: Significant diseases: Cataract, retinal disease (including diabetic retinopathy and other types of retinopathy), glaucoma, corneal disease, eyelid and orbital disorders, uveitis, strabismus and disorders of the ocular muscles, ocular neoplasms (malignancies, or cancers, and benign eye tumors), neuro-ophthalmologic disorders (including disorders of the optic nerve)
Eye examination with the aid of a slit lamp. Side view of a slit lamp machine. Cataract in human eye: magnified view seen on examination with the slit lamp. In ophthalmology and optometry, a slit lamp is an instrument consisting of a high-intensity light source that can be focused to shine a thin sheet of light into the eye.
Papilledema (right) revealed by scanning laser ophthalmoscopy (top) and laser Doppler imaging (bottom). Healthy contralateral eye (left). The signs of papilledema that may be seen using an ophthalmoscope include: venous engorgement (usually the first signs) loss of venous pulsation; hemorrhages over and/or adjacent to the optic disc
