Cheiroscope can test both the binocularity, presence and extent of suppression by a mirror that separates the image seen by the eyes. One eye sees reflected image and the other eye sees image being traced. With practice, the brain overlaps the image from both the eyes.
Existing models are not suitable for pediatric patients because their vertical viewing angle remains 0°. They are bulky and prone to distortion during transportation.
Our design of cheiroscope overcomes these challenges by folding into a compact form and inclines at 22.5°
This was given to 10 patients mean age 10..42 +/- 2.5 years for 3 months. Six children were anisometropic amblyopes with BSV on worth 4 dot test and four children were postop squint patients. Five anisometropes developed gross stereoacuity (2 developed 500″ of arc) & 2 out of 4 strabismic children developed gross stereoacuity
The new design cheiroscope is a useful device for binocular exercises.
