Dynamic visual acuity testing system

15 GUDID devices

An assembly of devices used to track changes in visual acuity during head movements primarily to quantify visual acuity loss due to vestibular pathology. The assembly typically includes a three-dimensional (3-D) integrating gyrometer (or equivalent) fastene...

Visual acuity projector

45 GUDID devices

A mains electricity (AC-powered) ophthalmic device intended to project an image on a screen to test visual acuity. The images typically include block letters (Snellen chart) and/or other symbols (e.g., recognizable objects used for children who cannot read)...

Visual acuity light box

19 GUDID devices

A mains electricity (AC-powered) light viewing box that uses a translucent version of the ophthalmic chart (Snellen chart) imprinted with block letters (optotypes) and/or other symbols (e.g., LEA symbols for children who can not read) in gradually decreasin...

Self-testing tone audiometer

3 GUDID devices

A battery-powered electroacoustic device that is designed for self-testing by the user to qualitatively evaluate hearing acuity by presenting a series of tones at a fixed level. It is placed over the user's ear and a microprocessor [central processing unit ...

Ophthalmic slit lamp, examination

330 GUDID devices

A mains electricity (AC-powered), ophthalmic, binocular microscope designed to examine the interior anatomy of the eye (anterior and posterior surfaces) by viewing through the iris. It produces a narrow slit of powerful light which is projected into the eye...

Tuning fork

192 GUDID devices

A hand-held, mechanical test instrument designed as an acoustic resonator used to test the hearing acuity of a patient, to diagnose hearing disorders, and to test for vibratory sense. It is usually made of stainless steel in the form of a two-pronged fork w...

Ophthalmic slit lamp, examination

75 GUDID devices

An electrically-powered, ophthalmic, binocular microscope designed to examine the interior anatomy of the eye (anterior and posterior surfaces) by viewing through the iris. It produces a narrow slit of powerful light which is projected into the eye, and res...

Ophthalmic examination slit lamp

72 GUDID devices

An electrically-powered, ophthalmic, binocular microscope designed to examine the interior anatomy of the eye by viewing through the pupil; it is not dedicated to surgical procedures. It projects a narrow slit of light into the eye and resulting light refle...

Vision testing/training chart

72 GUDID devices

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...

Tuning fork

40 GUDID devices

"A hand-held, mechanical test instrument designed as an acoustic resonator used to test the hearing acuity of a patient, to diagnose hearing disorders, and to test for vibratory sense. It is usually made of stainless steel in the form of a two-pronged fork ...

Vision/eye movement analysis system

35 GUDID devices

An electronic unit or device assembly intended to measure, record, and display a range of parameters associated with vision electrophysiology [e.g., electroretinogram (ERG), visual evoked potential (VEP), electrooculogram (EOG)], and/or psychophysical visio...

Vision physiology/eye movement analysis system

18 GUDID devices

An electronic unit or device assembly intended to measure, record, and display a range of ophthalmic parameters associated with vision electrophysiology [e.g., electroretinogram (ERG), visual evoked potential (VEP), electrooculogram (EOG)], and/or psychophy...

Hearing aid tester, electrical

3 GUDID devices

An assembly of electronic reference devices intended to be used by a healthcare provider in a clinical setting to verify the performance of and/or calibrate and assess the electroacoustic frequency and sound intensity characteristics emanating from a hearin...

Vision physiology/eye movement analysis system

3 GUDID devices

An electronic unit or device assembly intended to measure, record, and display a range of parameters associated with vision electrophysiology [e.g., electroretinogram (ERG), visual evoked potential (VEP), electrooculogram (EOG)], and/or psychophysical visio...

Intraocular telescope

2 GUDID devices

An implantable optical device designed to improve visual acuity in patients with bilateral moderate to profound central vision impairment due to age related macular degeneration. It is a non-active micro-Galilean telescope consisting of a doublet lens confi...

Electronic occlusion spectacles

1 GUDID devices

A battery-powered ophthalmic device designed to test and train vision for conditions where decreased visual acuity may be due to unequal vision in the eyes (e.g., presbyopia). It is in the form of spectacles with lenses that can independently be made opaque...
