An antique Ophthalmoscope by Philip Harris in it's original case, estimated to date from the 1910's. The case measures 25 x 5.5cm (10 x 2.25"). The scope and case are in good condition and original, one hinge on the case is broken. 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. It is done as part of an eye examination and may be undertaken as part of a routine physical examination. It is crucial in determining the health of the retina, optic disc, and vitreous humour. The pupil is a hole through which the eye's interior will be viewed. Opening the pupil wider (dilating it) is a simple and effective way to better see the structures behind it. Therefore, dilation of the pupil (mydriasis) is often accomplished with medicated eye drops before funduscopy. However, although dilated fundus examination is ideal, undilated examination is more convenient and is also helpful (albeit not as comprehensive), and it is the most common type in primary care.
