Binocular vision and orthoptics—investigation and management

In addition to routine Orthoptic clinics for adults and children we provide the following specialist clinics and services:. Home Services Orthoptics What we do. Services Browse by Location.

One of the most distinctively named ophthalmic instruments, this was primarily a home trainer for patient exercises but could also be used to examine for and demonstrate simultaneous vision for either colour or form. It folded flat for ease of portability and was made of lightweight black cardboard. It comprised two outer flaps bearing scales and a pointed central flap held upright by a cord which acted as a septum.

This also contained a covered mirror. It was used in conjunction with coloured objects usually pictorial cards , dull objects a copper coin was recommended and recognisable shapes such as a card bearing a letter U. To add entertainment value it was possible to play snap or noughts and crosses whilst using the device, or to conduct a tracing exercise using drawing paper.

A very simple form of device comprising a twin card holder with septum and handle. Its method of use always involved tilting the distal end upwards or downwards depending upon whether esophoria or exophoria was being treated. Surviving examples of this device are often missing their coloured filters.

A patient with heterophoria would see the spotlight apparently out of position and this could be plotted on the scale. The device only functioned correctly if held constantly at the exact distance of This device, also called the Turville Near Reflector TNR , was for testing visual and other binocular functions from a distance of circa 37cm. The Patent No.

Finally a note of warning This hand-held near vision test is in fact an 'Ever Ready' bicycle lamp battery pack with four colour filters mounted. One white, one red, two green. The patient would have been asked to hold the test unit at reading distance from his or her face. Worth's test was invented in but the hand-held version appeared in when AIM was the first company to convert a bicycle lamp.

Clement Clarke supplied the pictured version of this instrument with two hoods the Worth 4-dot and a duochrome test. The patient would hold the instrument at the reading distance whilst wearing diplopia goggles.

Introduction

Correctly set-up, the 4 dots are in diamond formation with red at the top, white below and green lateral filters. A patient wearing a red goggle over the right eye would see all four lights if possessing binocular vision or five! Rotating the hood served as a malingerer's test.

Binocular vision Binocular telescopes existed as far back as the 17th century but were never very common.

Orthoptic & Binocular Vision Association offers course for optometrists

Strabismus Squint in babies up to the age of four months is quite normal. Ambyloscope Amblyoscopes are fusion-training devices. Binocular Test of Cantonnet This binocular vision test from the s, last used in the optometry school at Glasgow Caledonian University , was designed by Monsieur A. Diploscope The memorable thing about this device was the 'DOG' card with which it was typically used. Pigeon-Cantonnet Stereoscope One of the most distinctively named ophthalmic instruments, this was primarily a home trainer for patient exercises but could also be used to examine for and demonstrate simultaneous vision for either colour or form.

Remy Separator A very simple form of device comprising a twin card holder with septum and handle. Other visual skills necessary for learning or sports, depth perception, peripheral vision, eye-hand coordination are also assessed.

BVC also carries out computer software based diagnosis, management of diplopia and other strabismus related issues using prism glasses. The goal of vision therapy is to optimize the visual system, and areas of the brain that control vision, visual efficiency, visual perception and other vision-related functions. By treating the entire visual system, vision therapy aims to change reflexive automatic behaviours to produce a lasting cure.

Vision therapy can treat vision problems that interfere with efficient reading among schoolchildren. The clinic comprising of the multidisciplinary team of Neuro-Ophthalmologists, Neurologists, Neuro-Optometrists and Vision therapy team focuses to advance the art and science of visual rehabilitation of the neurologically challenged population. The clinic also provides comprehensive assessment of visual efficiency and visual information processing to children with learning related vision problems. The Amblyopia Review clinic supports the pediatric ophthalmology services by reviewing patients with amblyopia who need amblyopia treatment and regular follow-up.

In the amblyopia review clinic, comprehensive assessment of visual functions is carried out for the amblyopic child and appropriate recommendations are provided in conjunction with the recommendations by the pediatric ophthalmologist. This clinic also addresses the visual needs of the amblyopic adult by appropriate assessment and management through novel treatment protocols such as action video games. Binocular vision is an important aspect of vision testing and efficient binocular vision is necessary for efficient reading skills in children and adults.

Binocular vision anomalies can significantly impair the reading and learning performance of children. Unless tested for the Binocular vision parameters, Binocular vision anomalies can be missed out in the routine screening or even in clinical practice. The community aspect of the binocular vision clinic, through the BAND Binocular vision anomalies and normative data study has addressed this issue in estimating the visual morbidity of binocular vision anomalies among school children.

The study has also successfully tested the efficacy of vision therapy in a community set-up. Another aspect of community responsibility of the binocular vision clinic is to support the occupational optometry services of Elite school of Optometry, helping to understand the visual demands pertinent to binocular vision in various occupations.

The Binocular vision research lab at the Srimathi Sundari Subramanian Department of Visual Psychophysics SSDVP focuses on understanding mechanisms of accommodation and vergence in subjects with binocular vision anomalies.

How do you get to see the Orthoptist?

Binocular vision clinic having understood the need for quality research in CI carries out many projects in this field. The current research work on Convergence insufficiency CI aims to demystify the underlying mechanism and the interaction between vergence and accommodation in CI. The CI participants undergo a comprehensive binocular vision examination following which standardized in-office vision therapy treatment is advised.

The resultant change in binocular vision parameters and changes in the cross-link ratios are assessed post vision therapy. Clinical research in Adult Amblyopia 14 years to 35 years of age is less known and practiced in India. One of our objectives is also to observe whether this innovative treatment modality can yield a long term sustainability of visual functions.
