“…However, none of our patients reported any history of these events. In all five cases, the palsy was monocular and sporadic, which differs from the few cases with dysplasia or absence of isolated extraocular muscles that are binocular and familial [15][16][17] . Due to the early onset of strabismus and amblyopia, none of our cases showed abnormal head positions, nor did they experience diplopia.…”

AIM: To investigate the clinical features and surgical outcomes of congenital dysplasia involving both inferior recti (IR) and medial recti (MR) muscles. METHODS: A retrospective review was conducted including cases of simultaneous congenital dysplasia of IR and MR that were diagnosed and surgically treated at the Zhongshan Ophthalmic Center, Sun Yat-sen University, China, from July 2009 to November 2019. Ocular motility, ocular alignment at distance (6 m) and near (33 cm) by prism alternating cover test and stereoacuity were assessed in all patients before and after surgery. RESULTS: A total of five patients (four males and one female; three with right eye and two with left eye congenital dysplasia) were included in this review. The patients ranged in age from 10 to 42y (21±13.4y). The main clinical findings were hypertropia and exotropia of the affected eye, along with motility limitations in adduction and depression. Lateral rectus (LR) recession/transposition combined with IR resection was performed in one case. Two scheduled surgeries were performed in four cases, with one involving superior rectus recession and IR resection and the others LR recession and MR resection. Mean±SD pre-surgical exotropia of 51.0±31.11 prism diopter (PD) and hypertropia of 29.20±7.12 PD in the primary position were decreased to 3.6±12.90 and 3.2±10.09 PD, respectively, at two years after surgery, with a success rate of 60% and an under-correction rate of 40%. CONCLUSION: The main clinical features associated with simultaneous MR/IR congenital dysplasia are hypertropia and exotropia of the affected eye along with motility limitations in adduction and depression. Scheduled two-stage surgeries achieved a success rate of 60%.

“… 2 who performed the first successful full-muscle transposition surgery in the congenital absence of a unilateral inferior rectus muscle. Thereafter, some authors 3 , 4 , 5 reported cases in which surgical treatment using full-muscle transposition was performed successfully. In order to reduce the risk of anterior segment ischemia, Paysse 6 reported a modified Jensen procedure in two cases with ruptured inferior rectus muscles and Kowal L 7 described a modified inverse-Knapp procedure in three cases of snapped inferior rectus.…”

“…In cases of an abnormal inferior rectus muscle accompanied by horizontal strabismus, the optimal surgical procedure has not been determined to date. There have been reports of a combination of a superior rectus weakening procedure and horizontal muscle recess−resect surgery, 8 , 9 the combination of muscle transposition and recess−resect surgery on the affected eye side, 4 , 10 and horizontal muscle surgery with a fellow eye. 10 The risk of anterior segment ischemia is a concern in multiple muscle surgery and attenuation of horizontal correction was reported in combination with muscle transposition and recess−resect surgery in the affected eye.…”

PurposeTo report a case of inferior rectus muscle hypoplasia with esotropia, which was treated successfully by resection and anterior transposition of the inferior oblique muscle.ObservationsA 1-year-old boy presented with esotropia. He had esotropia of 15–30° and intermittent left hypertropia. At the age of 3 years, the alternate prism cover test showed esotropia of 35Δ and left hypertropia of 25Δ. Magnetic resonance imaging of the orbit revealed left inferior rectus muscle dysgenesis. Strabismus surgery was performed and a hypoplastic left inferior rectus muscle was identified. We performed bilateral medial rectus muscle recession, and resection and anterior transposition of the left inferior oblique muscle. Nine months after the surgery, the patient had esotropia of 8Δ and left hypertropia of 6Δ.Conclusions and importanceResection and anterior transposition of the inferior oblique muscle is useful for hypoplasia of the inferior rectus muscle accompanied by horizontal strabismus.
