Progression of Stereopsis Recovery in Strabismic Patients: A One-Month and Three-Month Post-Surgery Evaluation

This prospective longitudinal observational study aims to assess stereopsis recovery in strabismic patients at one month and three months post-corrective surgery. The study will be conducted at Mayo Hospital, Lahore, and Sajjad Eye Center, Burewala, with a sample size of 34 using a purposive sampling technique. Eligible participants include patients aged ≥5 years undergoing strabismus surgery for esotropia, exotropia, or vertical deviations, with best-corrected visual acuity (BCVA) of 6/12 in both eyes. Patients with previous strabismus surgery, amblyopia, neurological conditions, or sensory strabismus will be excluded.

Baseline assessments include visual acuity (Snellen Chart), ocular alignment (cover-uncover and prism cover tests), and stereopsis (Titmus Fly Test). The same tests will be repeated one month and three months post-surgery to evaluate changes. The study aims to determine whether strabismus surgery enhances binocular function and stereopsis, helping guide future treatment strategies. Data will be analyzed using paired t-tests to assess differences over time.
