Diagnostic instruments designed as a combination of a direct ophthalmoscope and a retinoscope. These sets typically include ophthalmoscope and retinoscope heads and a handle with an internal battery that can be used either with the ophthalmoscope or the retinoscope head; they are usually available in housings. The handle frequently includes a battery charger. Most ophthalmoscope/retinoscope sets are used for primary care or emergency diagnosis, but some devices can also be used in surgery.
