Summary
The Matta Map effectively measures the field of single binocular vision in patients with incomitant strabismus. This quick and inexpensive method provides reproducible results for tracking patient progress.
Area of Science:
- Ophthalmology
- Vision Science
Background:
- Incomitant strabismus presents challenges in assessing visual fields.
- Accurate mapping of single binocular vision is crucial for patient management.
Purpose of the Study:
- To evaluate the efficiency of the Matta Map, a modified Lancaster Test, for mapping the field of single binocular vision.
- To assess the utility of the Matta Map in patients with incomitant strabismus.
Main Methods:
- The Matta Map, a variant of the Lancaster Screen, was used without fusion-dissociating spectacles.
- Patients tracked a target and reported single or double vision in nine cardinal positions.
- Multiple patients with incomitant strabismus were evaluated, with some undergoing serial assessments.
Main Results:
- The Matta Map demonstrated high utility in measuring the field of single binocular vision.
- Results were reproducible and correlated with patients' incomitant strabismus and symptoms.
Conclusions:
- The Matta Map is a rapid, inexpensive, and reliable tool for assessing single binocular vision fields.
- It facilitates monitoring of patient symptoms and progress over time.
