Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.
