Global Synoptophore Market Size 2020, By Application (Diagnostic, Therapeutic), Type (Manual, Automated), End Use (Hospitals, Clinics, Others) Region (North America, Europe, Asia Pacific, Latin America, Middle East and Africa) and Forecast 2017 to 2027

Synoptophore is an ophthalmic Instrument, used for diagnosing disorders of eye muscles and it is used for treating them through orthoptic methods. For many years, the Synoptophore was the standard ophthalmic instrument used in an orthoptic daily routine. It is the ideal ophthalmic instrument for the assessment and treatment of ocular motility disorders. It is the most common and comprehensive binocular vision assessment technique available today. Knowledge of basic stereoscopic binocular vision parameters is required not only for ophthalmologist but also for optometrists, who are able to provide, the correct prismatic correction and for visual training. Synoptophore range of slides can provide assessment on a wide range of binocular vision anomalies. The slides can aid the assessment of nine positions of gaze, indicate depth perception and stereopsis assessment can be obtained. Also, it can assess sensory fusion, perception, the presence of suppression and abnormal retinal correspondence. Slides can provide information on the presence of aniseikonia, when there is a difference in the perceived size of images. Some of its slides are designed for patients with ocular motility symptoms which require orthoptic treatment. All the standard measurements and treatments are possible on this instrument including assessment of cyclophoria, hyperphoria, horizontal vertical vergences.

On the basis of application, the market is segmented into diagnostics and therapeutics. The diagnostic segment dominated the market in 2020. Diagnostic uses of synoptophore include measurement of sensory and motor fusion. Sensory fusion is examined with images that are flawed but complement each other on the two slides. Central fusion (central fovea) is controlled with 2 degrees surface images, while peripheral fusion is controlled with larger images. Fusion control is done with the synoptophore set at the subjective angle of strabismus. The Motor fusion and the measurement of its amplitude is done by moving the arms of the synoptophore inward and outward. If there is a motor fusion, the eyes will converge or diverge to maintain sensory fusion. It is necessary to disclose the existence of minimal motor fusion otherwise the complete picture that the patient sees may be due to simultaneous perception.

North America accounted for the largest share of the global synoptophore market in 2020. Moreover, Asia is likely to show lucrative growth during the forecast period. Optometrists provide more than two-thirds of the primary eye care services in the United States. They are more widely distributed geographically than other eye care providers and are readily accessible for the delivery of eye and vision care services. There are approximately 32,000 full-time equivalent doctors of optometry currently in practice in the United States. Optometrists practice in more than 7,000 communities across the United States, serving as the sole primary eye care provider in more than 4,300 communities. In the United States Strabismus has an estimated incidence of 4% in the adult population. Commonest causes include unresolved or recurrent childhood strabismus, sensory strabismus, divergence insufficiency or sagging eye syndrome, Graves orbitopathy, 4th and 6th cranial nerve palsies and convergence insufficiency. Other notable causes include orbital trauma, third nerve palsy, myasthenia gravis, myopic strabismus fixus, skew deviation, retinal misregistration and strabismus occurring after other ophthalmic procedures.
