This was a prospective study of patients diagnosed with unilateral isolated inferior rectus OR) muscle palsy who required eye muscle surgery. Twenty-two patients with a mean age of26.6 ± 16.3 years (range 6 to 57 years) were included in the study. The cause of the IR paresis was trauma in twelve patients, congenital in nine patients, and vascular in one patient. Mean preoperative hypertropia was 18.0 ± 10.06 with distance fixation and 16.9 ± 9.96 at near fixation. Mean preoperative hypertropia in the field of action of the IR paresis was 25.6 ± 11.66 • Eight patients (36.3%) had no compensatory head posture, while the remainder had highly variable head postures among the group. The surgery performed for the first procedure was IR resection in thirteen patients (59.1%),IR resection and SR recession in seven patients (31.8%), contralateral IR posterior fixation suture in one patient (4.5%),and finally contralateral IR recession and posterior fixation suture in one patient (4.5%).Postoperatively mean follow-up was 9.6 ± 7.5 months. At the last follow-up fifteen patients (68%) had no deviation in primary and down-gaze, while four had a small hyperphoria and three were under-corrected with 8.106 residual hypertropia. Three patients underwent another eye muscle surgery. The authors conclude that many IR muscle paresis cases can be managed solely with IR muscle resection.

Strabismus 2015; 23:8-13. Cerebral palsy (CP) is characterized by muscle spasticity and is associated with a higher incidence of strabismus compared to the developmentally normal population. The success of strabismus surgery can vary due to unpredictable results using the standard operating nomogram. Therefore, alternative methods such as the use of botulinum toxin (BT) injection may be considered as an alternative. This prospective case series included 44 children with CP and infantile esotropia with no previous history of strabismus surgery. Mean age was 47.56 ± 30.86 months (range 5 to 124 months) with a follow-up range of 12-24 months. Group 1 was comprised of patients with esotropia ..506 and group 2 included patients © 2016 Board of Regents of the University of Wisconsin System, American Orthoptic Journal, Volume 66, 2016, ISSN 0065·955X, E-ISSN 1553-4448
