DEPTH PERCEPTION APPARATUS, OPHTHALMIC

The Depth Perception Apparatus, Ophthalmic, is a specialized vision screening tool designed to detect developmental vision disorders such as amblyopia, suppression, and strabismus in patients of all ages. It utilizes randomized dot patterns to present six geometric shapes that cannot be identified without corrective glasses, effectively discouraging guessing and ensuring accurate assessments. The device includes two test levels—500 and 250 seconds of arc—and offers graded circle and animal tests with sensitivity ranges from 400 down to 10 or 20 seconds of arc, allowing for precise measurement of stereoscopic acuity. The apparatus is engineered for ease of use and clinical effectiveness, making it ideal for widespread pediatric and general ophthalmic screening.
