Ophthalmoscopy
Ophthalmoscopy, (from Ancient Greek ὀφθαλμός (ophthalmós), meaning "eye", and σκοπέω (skopéō), meaning "to look") 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. It is crucial in determining the health of the retina, optic disc, and vitreous humor.[citation needed]
The pupil is a hole through which the eye's interior can be viewed. For better viewing, the pupil can be opened wider (dilated; mydriasis) before ophthalmoscopy using medicated eye drops (dilated fundus examination). However, undilated examination is more convenient (albeit not as comprehensive), and is the most common type in primary care.
An alternative or complement to ophthalmoscopy is to perform a fundus photography, where the image can be analysed later by a professional.
There are two major types of ophthalmoscopy:
Each type of ophthalmoscopy has a special type of ophthalmoscope:
Ophthalmoscopy is done as part of a routine physical or complete eye examination, mainly by optometrists and ophthalmologists. It is used to detect and evaluate symptoms of various retinal vascular diseases and eye diseases.
In patients with headaches, the finding of swollen optic discs (papilledema) on ophthalmoscopy is a key sign indicating raised intracranial pressure, which may be due to conditions such as hydrocephalus, benign intracranial hypertension (pseudotumor cerebri), and brain tumors. In glaucoma, cupped optic discs are seen. In patients with diabetes mellitus, regular ophthalmoscopic eye examinations (once every 6 months to 1 year) are important to screen for diabetic retinopathy, as visual loss due to diabetes can be prevented by retinal laser treatment if retinopathy is spotted early. In arterial hypertension, hypertensive changes of the retina closely mimic those in the brain and may predict cerebrovascular accidents (strokes).[citation needed]
During ophthalmoscopy, the pupil constricts due to light from the ophthalmoscope. To allow for better inspection of the posterior eye through the pupil, it is often desirable to dilate (enlarge) the pupil by applying a mydriatic agent (e.g. tropicamide), or by reducing the ophthalmoscope's brightness, which may slightly increase natural mydriasis.[citation needed]
