Strabismus, a constant or intermittent misalignment of the visual axes, interferes with saccade performance and binocular vision. It has been shown to impact on basic oculomotor functions (such as vergence) and complex capacities (such as reading) in both children and adults. Evidence suggests that overall reading performance improves postoperatively, although some deficits in eye movement behaviour may outlast surgical realignment. The nature of postoperative functional improvement for different types of strabismus, however, is largely unknown. In our ongoing interdisciplinary study we use eye tracking to investigate basic oculomotor functions and reading processes for monocular and binocular viewing in individuals with constant vs. intermittent strabismus. To investigate the effects of surgical correction we use a repeated-measures design consisting of a baseline- and a 4-months-postoperative-assessment. Focusing on single cases of our sample, we highlight methodological challenges associated with eye tracking in individuals with strabismus (e.g., poor visual acuity as a result of amblyopia, gaze estimation accuracy in difficult-to-calibrate participants). Preliminary results from ophthalmologic assessments, basic oculomotor tasks and their association with reading processes (pre-/postoperative design) in constant vs. intermittent strabismus are converged for clinical decision making and add to the discussion of 'cosmetic and/or functional repair'.
