Binocular Vision provides a step by step practical guide to the various techniques required in practice to assess the binocular status of patients, both young and old.

The programme guides optometrists through specific case studies to consider the appropriate management options for a broad range of anomalies. Presented by Professor Bruce Evans, the programme uses specific clinical cases and clinical footage of assessment techniques on real life patients to illustrate best practice in binocular vision assessment. Summary slides, graphics and animations aid understanding, and supportive reference links can be found throughout the course page and in the 'More information' section.

Test techniques considered include:

Cover-uncover
Alternating cover
Convergence assessment
Accommodation
Ocular motility
Fixation disparity
Foveal suppression
Stereopsis
Fusional reserves.

Learning outcomes

Communication

s.2 Communicate effectively with patients

Understand the best approach for taking history and symptoms to elicit information pertaining to any suspect binocular anomaly.

Clinical Practice

s.7 Conduct appropriate assessments, examinations, treatments and referrals

Understand the main techniques in the assessment of binocular status, including the cover/uncover test, motility, fixation disparity assessment, testing for compensation, NPC measurement and assessing fusional reserves.

s.5 Keep your knowledge and skills up to date

Understand, via the use of case studies, the management of a variety of binocular anomalies including comitant phoria and tropia and incomitancies.
