Excellent demonstration. This patient has Left eye deviating and Right eye fixating most of the time while fixating for distance but for near it was alternating. Would it be RT dominant or Left Dominant Exotropia. My Question is the dominant eye is the eye which fixates or the eye which Deviates?

I am having one blind eye and the same eye consists of a exotropia squint can it be corrected by prism glasses

[@ashiashraf9228]

For purely cosmetic purposes, using prisms to correct exotropia in a blind eye can be considered, though the effectiveness might be limited. Prisms can sometimes help align the eye to improve appearance, even if the eye does not have functional vision. However, the outcome will depend on several factors, including: • Degree of Deviation: The extent of exotropia may impact how effective prisms are in achieving a desired cosmetic result. • Patient’s Adaptation: The eye’s position relative to the head and overall appearance may change, but the lack of visual feedback means that adjustments might not be as stable or reliable as they would be for a seeing eye.

The HBT shows the reflex is on the limbus, how can it is corrected by 45 prism diopter…..¿

[@moineyetube]

As you can see it was corrected by more than 45 prism diopter prism by using prisms on both sides. The right side was a 30 D prism & left a 45 diopter prism
