Certified Ophthalmic Medical Technologist (COMT) Practice Exam

What is the main focus when evaluating the angle of deviation in strabismus?

1. Quality of vision

2. Angle of tropia

3. Patient comfort

4. Retinal health

The correct answer is: Angle of tropia

The primary focus when evaluating the angle of deviation in strabismus is indeed the angle of tropia. This measurement refers to the degree of misalignment of the eyes when fusion is disrupted, providing critical information about the severity and type of strabismus a patient may have. Understanding the angle of tropia allows ophthalmic professionals to determine the degree of deviation in both primary gaze and potentially under different conditions or positions of gaze. This measurement is essential for assessing how well the eyes are aligned and can help guide treatment decisions, such as whether surgical correction may be necessary or what type of prisms might be effective in management. While other factors like quality of vision, patient comfort, and retinal health are also important in the overall assessment of an individual's eye health and treatment plan, the angle of tropia is specifically focused on quantifying and understanding the nature of the strabismus itself. This quantification directly influences intervention strategies and monitoring for progression or improvement in the alignment of the eyes.
