Prism Bar Horizontal And Vertical PBCT

Glass Agencies presents the Prism Bar Horizontal and Vertical PBCT, a specialized ophthalmic diagnostic instrument used for the evaluation of ocular alignment, binocular vision, and strabismus assessment. This prism bar cover test tool is widely used in eye clinics, hospitals, and vision therapy centers for measuring the magnitude of ocular deviation in both horizontal and vertical planes. The prism bar consists of a series of accurately calibrated prisms arranged in increasing strengths, allowing clinicians to quantify deviation by neutralizing eye movement during cover testing. The horizontal prism bar assists in assessing esotropia and exotropia, while the vertical prism bar supports evaluation of hypertropia and hypotropia, enabling comprehensive binocular vision analysis. Each prism is clearly marked for easy identification, allowing smooth progression during examination and accurate recording of results. The compact and lightweight structure supports comfortable handling and stable positioning in front of the patient’s eye during testing. The transparent prism surfaces allow clear visibility of fixation targets, supporting consistent test conditions throughout the assessment. The instrument is suitable for use with both adult and pediatric patients, making it useful across a wide range of clinical scenarios. The prism bar is manufactured using high quality optical material that maintains clarity and consistent refractive properties over time. Smooth edges and a refined finish support safe handling and ease of cleaning between examinations. The structured alignment of prisms ensures dependable measurement response during alternate and simultaneous cover tests. This tool is commonly used alongside occluders and fixation targets to assess fusional control and binocular coordination. Its portable design allows easy storage in diagnostic kits and supports use in outreach screening programs as well as in-clinic examinations. Glass Agencies ensures each Prism Bar Horizontal and Vertical PBCT undergoes careful inspection for calibration accuracy, surface clarity, and structural integrity. When handled and stored according to standard ophthalmic guidelines, the instrument supports long term clinical use. Suitable for optometrists, ophthalmologists, orthoptists, and vision therapists, this prism bar remains an important component of binocular vision assessment.
