Purpose

To use a camera mounted device to record uniocular fields of fixation to measure the horizontal rotation of an eye by measuring limbal displacement using Goldmann perimeter in healthy subjects.


Methods

A camera device was used to record the uniocular fields of fixation using Goldmann perimeter in 10 healthy subjects. Screenshots were taken every 10 degrees of eye excursion in the horizontal axes. The position of the limbus in primary position was compared to the position of the limbus every 10 degrees of horizontal rotation, and the difference was measured.


Results

Limbal excursions in millimetres can be consistently measured using this method. The horizontal movement of the limbus reduces for every subsequent 10 degrees of rotation.


Conclusion

Quantification of limbal position and ocular rotation can be calibrated to determine eye excursions from photographs. This technique offers the ability to assess accurately the eye excursions from photography.
