DEVICE: GoCheck MultiScreener (B43071000020)

A hand-held, battery-powered, optical device intended for digital image capture and analysis of the external ocular anatomy to assist in the diagnosis of ophthalmic abnormalities (e.g., ptosis, strabismus, glaucoma); it is not intended to capture images of the fundus. It consists of a digital camera which includes software intended to take specific ocular measurements (e.g., pupil diameter, horizontal visible iris diameter, margin reflex difference, interpupillary distance, strabismus angle).

An electroacoustic device intended for use in a clinical setting to generate tones in the audible range to measure the hearing threshold of a patient by establishing the level at which the patient first becomes aware of the sounds. The device controls tone intensity and frequency either by a computer or manually, and displays/records the patient's responses, typically in the form of an audiogram. It may include a bone vibrator for direct inner-ear stimulation.

An ophthalmic chart or card printed with various symbols (e.g., letters, pictures or dots) intended to be used for testing visual acuity (e.g., Snellen chart) or testing and/or training accommodation and/or convergence or other amenable ophthalmic functions. The chart/card may be held in front of the patient or placed on a table or wall and may have specific user instructions depending on specific use. This is a reusable device.
