简要总结
This prospective comparative study aims to compare medial rectus (MR) muscle fenestration and recession in patients with partially accommodative esotropia (PAET). The main question it aims to answer is whether MR fenestration is equally effective as MR recession for PAET.
All patients will receive complete ophthalmic and orthoptic assessment. Patients will be randomly allocated using a random table to one of two groups; Group 1 will receive conventional MR recession, and Group 2 will receive MR fenestration.
详细描述
Inclusion criteria The study will include patients with accommodative esotropia if the residual distance deviation with full cycloplegic correction is > 15PD.
Exclusion criteria:
- Patients with convergence excess esotropia, defined as a near deviation with glasses exceeding that for distance by 15 PD or more.
- Patients with paralytic or restrictive strabismus.
- Patients with previous strabismus surgery
- Patients with neurologic, ocular, or developmental disorders or follow-up less than 6 months
All patients will receive complete ophthalmic and orthoptic assessment including:
i) A full ophthalmological assessment including history taking, measurement of uncorrected and best-corrected visual acuity, cycloplegic refraction, anterior segment examination, as well as a dilated fundus examination.
