Having good binocular vision is very essential in carrying out different daily visual demanding tasks such as reading, playing sports and driving. It helps people judging distance between objects (depth perception) precisely, and drives the eyes to move effectively and smoothly together. Binocular vision develops rapidly in the first few years after birth, therefore it is very important to check it at very young age to ensure appropriate treatment is provided if there are any abnormalities.

Strabismus (eye squint) is a rather common binocular vision abnormality. It can be generally classified by the direction of eye deviation (Esotropia as eyes turning in and Exotropia as eyes drifting out), and its frequency (constant or intermittent). Binocular visual therapy is usually effective in treating the following types of strabismus:

1. Intermittent Esotropia (Esophoria)
2. Intermittent Exotropia (Exophoria)
3. Constant Exotropia (Angle of deviation below 25 degree yields better results)

Visual therapy requires both parents and children to highly cooperate with the optometrists, and practise eye exercises regularly in order to succeed.

The following will show the equipment we have for advanced binocular vision assessment and visual therapy:
