Abstract
Purpose To investigate the types of strabismus surgeries performed and the reoperation rate in patients with Duane retraction syndrome (DRS). Design Retrospective cohort analysis. Participants An insurance claims data set was used to identify patients diagnosed with DRS between 2007 and 2021. Methods We recorded the type of strabismus surgery performed and the timing and frequency of reoperations. The hazard ratios (HRs) for reoperation were estimated according to the surgical methods using Cox regression analysis. Results Of the 9435 patients diagnosed with DRS, 1023 (10.8%) underwent ≥ 1 strabismus operation. The median age at surgery was 5.0 years, and patients were followed for an average of 3.8 ± 3.0 years after their initial strabismus surgery. Most of the surgeries only involved horizontal muscle(s) (n = 734 [71.7%]). However, some patients underwent surgeries on vertical muscle(s) (n = 132 [12.9%]), vertical muscle(s) with transposition (n = 102 [10.0%]), and horizontal muscle with transposition (n = 51 [5.0%]). The estimated 5-year rate of reoperation was 18.2% (95% confidence interval [CI], 15.0%-22.2%). Compared with surgery on horizontal muscle(s) only, vertical muscle surgery (HR, 2.01; 95% CI, 1.30-3.11; P = 0.002) and vertical muscle surgery coupled with transposition (HR, 1.79; 95% CI, 1.06-3.02; P = 0.03) had an increased risk of reoperation. Conclusions Strabismus surgery on ≥ 1 horizontal muscles is the most common type of strabismus surgery performed on patients with DRS. Approximately 1 in 7 patients with DRS who had strabismus surgery underwent a reoperation. Patients who underwent vertical muscle surgery had a higher risk of undergoing a reoperation.

Abstract
PURPOSE To evaluate refractive findings in patients with unilateral Duane's retraction syndrome (DRS). METHODS This retrospective study included 40 patients followed for unilateral DRS. Detailed ophthalmological examinations of the patients were performed. The spherical and cylindrical refractive error, spherical equivalent, and type of refractive error in the eyes with DRS and the fellow eyes were determined. The patients were divided into three subgroups according to their type of DRS. The refractive properties of the eyes with DRS were examined in subgroup analyses. Eye movement limitation was graded between +1 and +4 and compared according to the refractive error type. RESULTS The mean age of the patients was 16.8±12.6 (range, 1-60) years. Of the eyes with DRS, 11 (27.5%) were emmetropic, four (10%) were hyperopic, two (5%) were myopic, 11 (27.5%) were myopic astigmatic, and 12 (30.0%) were hyperopic astigmatic. There was no statistically significant difference between the eyes with DRS and fellow eyes in relation to the spherical or cylindrical refractive errors or spherical equivalent (P>0.05 for all). The refraction values for the patients with type 1, type 2 and type 3 DRS were similar between groups (P>0.05). No statistically significant difference was detected in the degree of eye movement limitation according to refractive status (P>0.05). CONCLUSION In patients with unilateral DRS, there was no significant difference between the affected eyes and the fellow eyes in terms of refractive error values or types. Refractive status did not significantly differ according to the degree of eye movement limitation. Therefore, although extraocular muscles are affected by DRS, there may not be any significant refractive changes.

Abstract
PURPOSE To report the visual and refractive characteristics and the prevalence of amblyopia in patients with different types of Duane's Retraction Syndrome (DRS). METHOD This retrospective study was performed on hospital records of 582 DRS patients at Farabi Hospital, Iran, from 2012 to March 2022. RESULTS The mean age of patients was 19.4 ± 11.9 (range, 3-70) years [335 (57.6 %) females and 247 (42.4 %) males (P < .001)]. DRS type I, II, III, and IV were presented in 347 (59.6 %), 148 (25.4 %), 82 (14.1 %), and 5 (0.9 %) patients, respectively. There were 530 (91.1 %) patients with unilateral and 52 (8.9 %) with bilateral involvement. In the unilateral patients, the DRS eyes' corrected distance visual acuity (CDVA) and astigmatism were significantly worse than the Non-DRS Eyes (P < .001). The mean amount of all refractive and visual parameters in bilateral patients' right or left eyes was significantly lower than in unilateral patients' non-DRS eyes (all P < .05). Anisometropia was observed in 75(12.9 %) of the patients. Amblyopia was observed in 18.5 % (98 patients) and 36.5 % (19 patients) of unilateral and bilateral DRS patients, respectively (P < .001). In unilateral patients, amblyopia was found in 57 (16.4 %) patients with Type I, 22 (14.9 %) patients with Type II, 16 (19.5 %) patients with Type III, and 3 (60 %) patients with Type IV. Forty-four (37.6 %) of patients with amblyopia had anisometropia. CONCLUSION This large-scale study indicates that DRS types differ in terms of refractive error, visual acuity, and the prevalence of amblyopia and anisometropia. Clinicians should be aware of the clinical features associated with different types of DRS.

Abstract
Duane syndrome is one of the most common restrictive congenital strabismus characterized by variable horizontal duction deficits with globe retraction and shoots on attempted adduction and narrowing of the palpebral aperture. It is now listed as a congenital cranial dysinnervation disorder. The disease is usually unilateral with female preponderance. Basic etiopathogenesis involves dysinnervation of the lateral rectus (LR) due to aplastic/hypoplastic abducens nucleus with a secondary aberrant supply to the LR by the medial rectus (MR) subnucleus of the oculomotor nerve. Diagnosis of the disease is usually clinical. Due to the variable presentation of the disease, surgical management is a challenge and has to be individualized to achieve alignment in the primary gaze, reduction in globe retraction, upshoots and downshoots, and correction of any abnormal head posture. Differential recessions of the lateral and MR muscles are done to correct esotropia or exotropia in the primary gaze. For globe retraction and shoots, Y-split or periosteal fixation of the LR muscles is done depending on the severity.

Abstract
A two year presented to the clinic with abnormal head posture and right-sided face turn since birth. On examination, he showed a large right face turn of 40° while concentrating on a near target. His ocular motility assessment showed a -4 limitation of adduction in the left eye with 40 prism diopters (PD) exotropia and grade 1 globe retraction of the left eye. He was diagnosed with type II Duane retraction syndrome (DRS) in the left eye and planned for lateral rectus recession of both eyes. Postoperatively, the patient was orthotropic at distance and near in primary gaze with resolved face turn and improvement of limitation of adduction to -2, but some limitation of abduction -1 in the left eye was observed. Herein, we discuss the clinical features, etiologies, tailored evaluation, and management for type II DRS patient.

Abstract
Duane retraction syndrome (DRS) with mechanical and innervational upshoot poses a surgical challenge. We discuss a case of DRS with mechanical and innervational upshoot and its surgical management. An 11-year-old boy presented with left eye upward deviation since birth. This deviation was worst on the right gaze. His best corrected visual acuity was 6/6 OD and 6/60 OS. Refraction showed low hyperopia with low astigmatism in both eyes. Stereoacuity was absent and there was suppression on the Worth 4 dot test in the left eye. The left eye had large hypertropia of 50 prism diopter in primary gaze. Extraocular movements showed severe upshoot and narrowing of palpebral fissures on adduction and limited abduction (-2). The patient underwent Y-splitting of the left lateral rectus (LR) muscle of 10 mm, LR recession of 4 mm, and left eye superior rectus recession of 12 mm. A marked reduction in hypertropia in primary gaze was observed on day one and at two months postoperatively with residual upshoot on adduction. His left eye deviation remained stable after six months postoperatively.

Abstract
PURPOSE To evaluate the clinical findings of different types of Duane retraction syndrome (DRS). STUDY DESIGN Retrospective. METHODS This study was performed on 691 patients with DRS who underwent surgery. Clinical examinations included laterality, abnormal head posture (AHP), corrected distance visual acuity (CDVA), refractive error, amblyopia, deviation, overshoots, and type of surgery. RESULTS The mean age of patients with DRS was 16.7 ± 12.5 (range 1.0-73) years. The patients included 396 (57.3%) women and 295 (42.7%) men (P < 0.001). DRS type I, was observed in 429 (62.1%), II in 168 (24.3%), III in 88 (12.7%) and IV in 6 (0.9%) patients. Unilateral DRS was observed OS in 628 (90.9%) [471 (%78.9) and OD in 157 (21.1%) eyes (P < 0.001)]. O ther clinical findings were AHP (n = 522, 78.1%), overshoot (n = 236, 34.2%) and amblyopia (n = 118, 17.1%). The prevalence of overshoot in types I, II, and III was 17.5% (75/429), 60.7% (102/168) and 64.8% (57/88), respectively (P < 0.001). The prevalence of amblyopia was significantly lower in patients with AHP (80/522, 15.3%) compared to patients with normal head posture (38/169, 22.5%) (P = 0.023). The mean angle of deviation in the primary position (PP) at distance was 21.7 ± 11.5 △ for esotropic group and 17.8 ± 12.4 △ for exotropic group. Sixty-two (9.0%) patients required second surgery for resolving residual misalignment (1.1 surgeries for each patient). CONCLUSIONS About two-thirds of DRS patients had AHP, one-third had overshoots, and one-sixth had amblyopia. The results show that different types of DRS are associated with different epidemiological and clinical characteristics.

Abstract
Various surgical approaches have been described for the management of Duane retraction syndrome (DRS), a type of congenital cranial dysinnervation disorder (CCDD), the goals of which include correcting the primary position deviation and abnormal head posture (AHP), minimizing globe retraction and overshoots and improving the ocular rotations. Vertical rectus transposition (VRT) is one such technique, found more effective in improving abduction and thereby expanding the field of binocular vision, as compared to horizontal muscle surgery. VRT, however, is associated with the risk of inducing vertical deviations and also poses a risk for development of anterior segment ischemia. To overcome these concerns, transposition of only the superior rectus to the lateral rectus was proposed and evaluated to reveal improvement in alignment, AHP and motility comparable to VRT but with lesser surgical time and fewer post-operative complications. With promising results in the management of DRS, superior rectus transposition (SRT) has been extensively studied and has evolved over the last decade with several modifications to further increase the efficiency and reduce the risk of post-operative complications. This article focusses on the pre-operative considerations while planning SRT in DRS, various approaches and surgical techniques described, and the outcomes and complications of SRT in DRS. The role of SRT in the management of other CCDDs may be explored with further studies.

Abstract
Objective In this study, we aimed to investigate the prevalence of diplopia in cases with type 1 Duane retraction syndrome (DRS). Materials and methods This study was a retrospective review of cases involving patients presenting diagnosed with DRS over a period of 24 years. Among these cases, 28 had type 1 DRS and fulfilled the inclusion criteria. The cases were evaluated in terms of age, gender, affected eye, concomitant ocular motility disorders, presence of amblyopia, manifest shift, abnormal head position (AHP), fusion, and stereopsis. Results Sixteen of the patients (57.1%) in the study were female, and 12 (42.8%) were male; the mean age of the patients was 18.9 years (range: 7-67 years). The right eye was affected in six of the cases (21.4%), and the left eye in 22 (78.6%) of the cases. On examination, diplopia was not observed in 21 (75%) cases, but it was detected in seven (25%). AHP was present in five of the seven cases with diplopia and not present in two, and all seven of the diplopic cases had fusion, while three had stereopsis. The level of stereopsis in all diplopic cases was 400 sn/ark. When the clinical findings of patients with diplopia and those without diplopia were compared, a statistically significant difference was observed only in terms of AHP. Conclusions Although diplopia is not one of the clinical features of DRS, it must be noted that in cases with type 1 DRS, diplopia may occur in directions in which the movement of the eyeball is limited. In the presence of this finding, which might mimic sixth nerve palsy, patient history must be diligently taken, other clinical findings of DRS must be thoroughly examined, and an MRI should be performed when necessary for an easier diagnosis.

Abstract
PURPOSE To report ocular motility patterns that mimic, but do not fulfil the full clinical picture of Duane retraction syndrome (DRS) and to describe their clinical features and surgical management. METHODS This is a retrospective case series study conducted on patients with DRS, mimicking non-comitant exotropia or esotropia and a face turn. Patients were included only if they lacked either globe retraction on adduction (sine retraction) or limitation of adduction or abduction on ductions (sine limitation not >0.5). Any overshoots or pattern strabismus was recorded. The ocular motility and alignment, details of surgery and their surgical outcomes were analysed. RESULTS Twenty-one patients were identified; 13 in the sine retraction and 8 in the sine limitation group. All patients presented with a compensatory face turn. Overshoots were present in 10 (77%) and 7 patients (88%) in the sine retraction and sine limitation groups, respectively. Forced duction test showed tightness of the ipsilateral medial and the ipsilateral lateral rectus muscle in esotropic (n = 3) and exotropic patients (n = 18), respectively. Orthotropia was achieved in 82% of patients following ipsilateral medial or lateral rectus muscle recession. CONCLUSIONS There is a subset of patients who present with motility pattern similar to DRS but lack its complete diagnostic criteria. The presence of a face turn, overshoots on adduction or an ipsilateral tightness of the affected muscle should make one consider DRS sine retraction/sine limitation. The patients in our study responded well to lines of management similar to those of DRS.

Abstract
Duane retraction syndrome is a congenital eye movement disorder characterized by a failure of abducens nerve to develop normally, resulting in restriction or absence of abduction, adduction, or both, and narrowing of the palpebral fissure and retraction of the globe on attempted adduction. There is a genetic heterogeneity in Duane retraction syndrome (DURS). DURS maps to chromosome 8q13 in some patients, and pathogenic variants in CHN1 and MAFB genes are known to lead to DURS. We report here a child and his father with Duane retraction syndrome, associated to swallowing difficulties and unilateral trapeze aplasia. A whole exome sequencing revealed a heterozygous missense variant in CHN1 gene. This gene encodes GTPase-activating protein and is involved in the assembly of neuronal locomotor circuits. A patient with a 8q deletion has previously been described with a Duane retraction syndrome associated to trapeze aplasia. We provide an additional description to support the role in cranial nerves development of the CHN1 gene.

[PMID: 33607271 DOI: 10.1016/j.jaapos.2020.10.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/30/2020] [Revised: 08/23/2020] [Accepted: 10/02/2020] [Indexed: 11/21/2022]
Abstract
PURPOSE To present the clinical features of 4 patients with Duane retraction syndrome characterized by synergistic divergence or convergence, abnormal vertical movements, and accessory fibrotic bands. METHODS The medical records of 4 patients were reviewed retrospectively for the following clinical manifestations: visual acuity, refraction, ocular alignments, ocular motility, head position, magnetic resonance imaging, surgical techniques, and outcomes. RESULTS All 4 cases were diagnosed as variants of Duane retraction syndrome. Two cases (cases 1 and 2) had synergistic divergence with unilateral adduction deficit, and 2 (cases 3 and 4) had synergistic convergence with bilateral abduction deficit. Case 2 manifested abnormal vertical movements of the right eye, which goes down with adduction of the left eye and goes up oppositely with abduction of left eye. Accessory fibrotic bands were detected beside the medial rectus muscle of both eyes in case 3. Synergistic convergence in case 4 occurred only after the first strabismus surgery. Weakening of the misinnervated horizontal rectus muscle improved ocular alignment and head position in cases 1, 3, and 4. CONCLUSIONS Synergistic divergence and convergence are extremely rare and may present with a great diversity of clinical features. A good outcome is very difficult to achieve; however, weakening of the misinnervated horizontal rectus muscle was therapeutic in these patients.

Abstract
A 10-year-old boy presented with complaints of abnormal eye movements and face turn since early There was a limitation of adduction in LE with narrowing of palpebral fissure and downshoot characteristic of type 2 Duane Syndrome. He was a known case of Arthrogryposis multiplex congenita (AMC) and had undergone multiple orthopedic surgeries. The literature on Duane Retraction Syndrome (DRS) in AMC is limited. Here, we report in brief the association of DRS type 2 in AMC.

Abstract
A fixation preference for the affected eye is uncommon in patients with unilateral Duane retraction syndrome (DRS), and surgery on the fellow eye is rarely advocated. We are presenting a case report of a 9-year-old boy with unilateral DRS type II in the left eye who received lateral rectus muscle recession in his right amblyopic eye. The patient was orthophoric and his face turn was gone 6 months postoperatively. Surgery on the fellow amblyopic eye is a good choice for unilateral DRS where the affected eye dominants the fixation, and the satisfactory outcome suggests that alignment in the primary position can correct the face turn effectively despite the muscle duction deficit in the affected eye and further extend the binocular single visual field.

Abstract
PURPOSE To report surgical outcomes of patients with exotropic Duane retraction syndrome. METHODS A retrospective review of the medical records from patients with exotropic Duane retraction syndrome who underwent strabismus surgery and had at least 2 months of postoperative follow-up was conducted. Surgical success was defined as a postoperative horizontal deviation within 8 prism diopters (PD), abnormal head posture (AHP) less than 5 degrees, and a two-step decrease in overshoots. RESULTS Seventy-three patients with exotropic Duane retraction syndrome (38, 52% male, mean age 14 ± 7.9 years) met the study criteria. Unilateral type 3 Duane retraction syndrome was seen in 56 (77%) patients and type 1 in 14 (19%) patients. The mean follow-up period was 22 weeks (range: 8 to 209 weeks). Unilateral and bilateral lateral rectus recession were performed in 48 (65%) and 25 (34%) patients, respectively. In addition to recession, a lateral rectus Y-splitting was performed in 42 (56%) patients. Five patients underwent differential medial rectus and (larger) lateral rectus recession to alleviate severe globe retraction. The mean primary position reduced from 23 PD (CI: 19.6 to 26 PD) preoperatively to 9 PD (CI: 7.02 to 11.02 PD) postoperatively (P < .0001). Postoperatively 50% of patients were orthotropic in the primary position. Surgical success for primary position deviation, AHP, and overshoots were achieved in 74%, 81%, and 71% of patients, respectively. CONCLUSIONS In the current study, type 3 Duane retraction syndrome was the most common subtype necessitating surgery for exotropic Duane retraction syndrome. Good surgical outcomes were obtained for various indications. Unilateral or bilateral lateral rectus recession was successful in improving motor alignment and AHP. The addition of lateral rectus Y-splitting corrected overshoots greater than grade 2 in most patients with exotropic Duane retraction syndrome. [J Pediatr Ophthalmol Strabismus. 2021;58(1):9-16.].

Identification of a novel CHN1 p.(Phe213Val) variant in a large Han Chinese family with congenital Duane retraction syndrome. Sci Rep 2020; 10:16225.

Abstract
Duane retraction syndrome (DRS) is a neuromuscular dysfunction of the eyes. Although many causative genes of DRS have been identified in Europe and the United States, few reports have been published in regard to Chinese DRS. The aim of the present study was to explore the genetic defect of DRS in a Chinese family. Exome sequencing was used to identify the disease-causing gene for the two affected family members. Ophthalmic and physical examinations, as well as genetic screenings for variants in chimerin 1 (CHN1), were performed for all family members. Functional analyses of a CHN1 variant in 293T cells included a Rac-GTP activation assay, α2-chimaerin translocation assay, and co-immunoprecipitation assay. Genetic analysis revealed a NM_001822.7: c.637T > G variant in the CHN1 gene, which resulted in the substitution of a highly conserved C1 domain with valine at codon 213 (NP_001813.1: p.(Phe213Val)) (ClinVar Accession Number: SCV001335305). In-silico analysis revealed that the p.(Phe213Val) substitution affected the protein stability and connections among the amino acids of CHN1 in terms of its tertiary protein structure. Functional studies indicated that the p.(Phe213Val) substitution reduced Rac-GTP activity and enhanced membrane translocation in response to phorbol-myristoyl acetate (PMA). Together with previous studies, our present findings demonstrate that CHN1 may be an important causative gene for different ethnicities with DRS.

Abstract
PURPOSE To compare the results of augmented superior rectus transposition (with or without medial rectus recession) with simple medial rectus recession in the treatment of patients with esotropic Duane retraction syndrome. METHODS This was a prospective, randomized, and interventional comparative study of 20 patients with esotropic type 1 Duane retraction syndrome. Patients were randomly divided into two groups. In the first group (superior rectus transposition group), superior rectus transposition with or without medial rectus recession was performed. In the second group (non-superior rectus transposition group), unilateral medial rectus recession was performed. RESULTS Each group included 10 patients. Esotropia improved from 20.4 prism diopters (PD) preoperatively to 0.6 PD postoperatively in the superior rectus transposition group and from 22.5 PD preoperatively to 0.9 PD postoperatively in the non-superior rectus transposition group. Face turn improved from 11.5° preoperatively to 0.5° postoperatively in the superior rectus transposition group and from 12° preoperatively to 1.5° postoperatively in the non-superior rectus transposition group. Abduction improved in the superior rectus transposition group from -3.9 preoperatively to -3.1 postoperatively and from -3.9 preoperatively to -3.6 postoperatively in the non-superior rectus transposition group. Vertical deviation developed in two cases in the superior rectus transposition group. CONCLUSIONS Both superior rectus transposition and medial rectus recession are effective in the elimination of esotropia and face turn in patients with esotropic Duane retraction syndrome. Superior rectus transposition is more effective in improving abduction, but it can be complicated by vertical deviation. [J Pediatr Ophthalmol Strabismus. 2020;57(5):309-318.].

Abstract
SIGNIFICANCE The overall objective of this study was to evaluate facial asymmetry in patients with unilateral Duane retraction syndrome (DRS). The results showed a high frequency of facial asymmetry parameters of the opposite side of head turn in unilateral DRS patients. PURPOSE The purposes of this study were to evaluate the characteristics of facial asymmetry in unilateral exotropic and esotropic DRS and to compare the findings with orthotropic subjects. METHODS This cross-sectional comparative case series study was performed in 44 consecutive patients with head turn caused by DRS and 44 orthotropic subjects from 2016 to 2019. Four pictures were taken from the patients' faces. The first and second pictures were taken when patients had head turn and when the head was completely straight for calculating the facial angle and relative facial size, respectively. The third and fourth pictures were taken when the head was positioned downward (to compare the size of the cheek) and upward (to evaluate nose asymmetry). RESULTS The mean ± SD age of DRS patients and orthotropic subjects was 16.23 ± 9.92 and 20.68 ± 11.82 years, respectively. The frequency of facial asymmetry and all facial parameters (cheek compression, nasal tip and columella deviation, and compression of one of the nostrils) was significantly higher in DRS patients compared with orthotropic subjects (P < .001). In DRS patients with facial asymmetry, columella and nasal tip deviation (P = .006) and cheek and face compression (P = .03) were significantly more prevalent in the opposite direction of head turn. In the DRS group, the mean ± SD age of the patients with and without facial asymmetry was 17.37 ± 9.76 and 7.40 ± 6.54 years, respectively (P = .02). CONCLUSIONS The frequency of facial asymmetry and all facial parameters was significantly higher in DRS patients compared with orthotropic subjects. In unilateral DRS patients, the face was more commonly affected on the opposite side of head turn.

Abstract
Purpose To assess the clinical characteristics of Duane Retraction Syndrome (DRS) in Al-Medina region, in patients attending a pediatric ophthalmology clinic at Ohud Hospital. Method A cross-sectional observational study was conducted from October 2017 to June 2018 at Ohud Hospital, Al-Medina region, Saudi Arabia. Data was collected using a sheet containing eighteen simple items which include demographic data, family history, surgical history, the clinical characteristics of the disease and the physician's treatment plan. Twenty patients were included in this study. Results All twenty patients included in the study were diagnosed with DRS type I. Male and female were symmetrical in numbers as both 10 (50.0%) respectively. The mean age of the subjects was 8.7 years (SD 9.6). 95% of the subject were unilaterally affected while five percent of them were affected both sides of the eyes. 75% of the patients were affected on the left eye while 20% were affected on the right side. 35% of the patients had amblyopia in the affected eye. 25% of the patients had an abnormal head position. Abnormal eye movement (upshoot and downshoot) more common when the right eye is affected (p-0.035). 75% of the patients were orthotropic while 30% had esotropia. 75% of patients were positive of parents' consanguinity. 16 patients (80.0%) were from Al-Medina city while four of them (20.0%) were from the different area of Al-Medina region (Al Hejeria, Al Henakia, Omluj, Yatmah). Conclusion This cross-sectional observational study is the first one that evaluates DRS in Al-Medina region. Associated abnormal eye movement more common when the right eye is affected. Parents' consanguinity may play a role in the occurrence of DRS as it is not considered as a rare disease in our region. Therefore, more studies are needed to establish the relationship between the occurrence of DRS and parents' consanguinity in our region. Also, further studies are needed to establish the relationship between abnormal eye movement and the involvement of the right eye.

Abstract
AIM The aim was to evaluate the long-term motor outcome of superior rectus transposition procedure in patients affected by unilateral esotropic Duane retraction syndrome with residual esotropia and anomalous head position. METHODS A retrospective analysis of medical records of patients affected by esotropic Duane retraction syndrome who underwent superior rectus transposition procedure as reoperation for residual esotropia and/or residual anomalous head position. Amount of deviation, anomalous head position, duction limitation, globe retraction, presence of upshoot/downshoot, and vertical deviation were analyzed before and after superior rectus transposition procedure. RESULTS Twenty patients were selected. All patients underwent unilateral medial rectus recession or bilateral medial rectus recession, for unilateral esotropic Duane retraction syndrome at least 2 years before superior rectus transposition reoperation. Mean age at surgery (superior rectus transposition) was 12 ± 6.8 years, and the follow-up period was 2.7 ± 0.6. Mean deviations at distance and near before surgery were 19.5 ± 5.7 and 15.2 ± 6.8, respectively. Two patients showed upshoot. Head turn was 11.4 ± 5.1°; abduction limitation was -2.6 ± 0.9. After superior rectus transposition, all patients showed an improvement of esotropia at distance and near (8.1 ± 5.7 and 5.1 ± 5.6, respectively; p < 0.05), anomalous head position (5.6 ± 3.9°; p < 0.05), and abduction limitation (-2.3 ± 0.8; p < 0.05). No statistically significant changes occurred in globe retraction. No adduction limitation, vertical deviation, and upshoot/downshoot were present after superior rectus transposition procedure. Results were stable during follow-up. CONCLUSION Superior rectus transposition procedure is an effective procedure in esotropic Duane retraction syndrome patients who previously undergone unilateral/bilateral medial rectus recession, with residual esotropia and anomalous head position. It allows improvement of esotropia, head turn, and partial recovery of abduction in a significant percentage of patients (30%) with no vertical complications.

Abstract
Duane's Retraction Syndrome (DRS), a congenital cranial dysinnervation disorder, accounts for 5% of all strabismus. A vascular anomaly in DRS, which became clinically relevant in the context of significant epistaxis, is presented. A 15-year-old girl with DRS underwent a rhinological procedure for traumatic nasal deformity and suffered large volume epistaxis. Using angiography, an anatomical variation was identified, noting the ophthalmic artery was supplied by branches from the sphenopalatine artery, facial artery, and middle meningeal artery; not from the internal carotid artery. Hence epistaxis control was achieved via alternative methods, and unilateral blindness was avoided.

Abstract
PURPOSE To describe the clinical features of Duane's retraction syndrome in a cohort of South African children and to analyze the differences between ethnic groups. METHODS A retrospective case series of 120 patients seen between 1997 and 2017 at a tertiary referral center in Cape Town, South Africa. RESULTS Type 2 Duane's retraction syndrome was most common in black children (54%), whereas type 1 was predominant in mixed race (68%) and white (94%) children. In this cohort, 63% of black children with Duane's retraction syndrome were boys, whereas 69% of white children and 59% of mixed race children were girls. Left eye involvement was the most common in all ethnic groups (44%), followed by right eye (41%) and bilateral (14%) involvement. The average age at presentation was 34.2 months (range: 1 to 144 months). Strabismus in primary position was present in 57 patients (46%), of whom 39% had esotropia and 61% had exotropia. A deviation in the primary position was more common in black (71%) children than in mixed race (39%) or white (41%) children. Ametropia was found in 94 patients (79%), amblyopia was present in 15 patients (13%), and 41 patients (34%) underwent surgery. CONCLUSIONS This is the first study to provide robust data on the profile of pediatric Duane's retraction syndrome in the three main ethnic groups in South Africa, and it showed clear ethnic differences. Among black children, boys are affected more often, the proportion with type 2 Duane's retraction syndrome is more frequent, and surgery is required more often. Among white and mixed race children, girls are affected more often and type 1 Duane's retraction syndrome is predominant. [J Pediatr Ophthalmol Strabismus. 2019;56(4):248-253.].

Abstract
PURPOSE To investigate clinical findings of the pseudo inferior oblique overaction (IOOA) syndrome and the outcomes of strabismus surgery and to discuss the mechanisms proposed for this disease. METHODS This syndrome is defined by Y pattern strabismus with exotropia in upgaze. There is marked abduction and hypertropia of the adducting eye when elevation is carried out in side gaze, but there is no hypertropia of the adducting eye in horizontal side gaze. Sixteen patients were included and surgery was performed in 14 patients. Success of the surgical intervention was defined as correction of the Y pattern, orthotropia in primary position, upgaze, and downgaze. RESULTS Thirteen of the sixteen patients were female. The mean age was 9.6 ± 6.1 years. The mean follow-up time was 14.7 ± 16.9 months. Pre-operatively, 12 patients were orthophoric, and four patients were exophoric (4 to 8 PD) in primary position. In downgaze, all patients were orthophoric. Mean exotropic deviation in upgaze was 25.06 ± 5.9 (18 to 40 PD). Fourteen patients underwent surgery with 2-mm bilateral lateral rectus recession and full tendon supraplacement in seven cases, and 2/3 tendon supraplacement in the other seven patients. The success rate of surgery was 92.8% after the first operation, which reached 100% after a second surgical procedure was performed on one of the patients. CONCLUSIONS Strabismus surgery is effective in correcting the Y pattern in patients with pseudo IOOA. A 2/3 tendon supraplacement combined with 2-mm recession of the lateral rectus muscles is the preferred treatment.

Abstract
Duane retraction (or co-contraction) syndrome is a congenital restrictive strabismus which can occur either as an isolated entity or in conjunction with other congenital anomalies and is now listed as a congenital cranial dysinnervation disorder. It is characterized by co-contraction of horizontal recti on attempted adduction causing globe retraction along with variable amounts of upshoots or downshoots. It may have limited abduction or adduction or both and present as esotropic, exotropic, or orthotropic Duane. The diagnosis of this disease is usually clinical. However, recent research has provided a greater insight into the genetic basis of this disease paving a way for a greater role of genetics in the diagnosis and management. This disease can have a varied presentation and hence the treatment plan should be tailor-made for every patient. The indications for surgery are abnormal head posture, deviations in the primary position, retraction and narrowing of palpebral aperture and up- or downshoots during adduction, and sometimes also to improve abduction. The arrival of newer surgical techniques of periosteal fixation (PF) of lateral rectus (LR), partial vertical rectus transposition, or superior or inferior rectus transposition in addition to LR recession with Y-split has vastly improved the management outcomes, providing not only primary position orthophoria but also increased binocular visual fields as well.

Abstract
PURPOSE To describe the clinical features of patients with Duane retraction syndrome (DRS) and evaluate the outcomes of surgical approaches based on the characteristics of each patient. METHODS The records of 38 Caucasian subjects with DRS were retrospectively reviewed. The patients were classified as type I, II, or III based on the Huber Classification. Ten patients underwent unilateral medial rectus (MR) recession due to abnormal head posture (AHP) and/or esotropia. Four patients underwent Y-splitting and recession of the lateral rectus (LR) with MR recession due to AHP and/or esotropia, upshoot, and globe retraction. RESULTS There was a preponderance of unilaterality, female gender, left eye, type I, orthotropia, upshoot, and low refractive error. All patients demonstrated globe retraction and fissure narrowing. AHP was only present in unilateral cases. Nine patients had amblyopia. More than half of the patients over 5 years of age had decreased stereopsis. MR recession decreased AHP to less than 8° in all patients. Y-splitting and recession of the LR eliminated upshoot in all four patients. One patient who underwent an 8-mm MR recession demonstrated -2 adduction limitation. CONCLUSIONS The DRS patients in our study demonstrated features that are consistent with previous reports in the literature. This study emphasizes the need to consider disease classification in the surgical management of DRS patients.

Abstract
Duane's retraction syndrome is associated with various ocular and systemic abnormalities. We report a case with bilateral Duane's retraction syndrome type I accompanied by renal agenesis, vesico-ureteral reflux, patent ductus arteriosus, and external ear malpositioning. Because of disabling consequences, we recommend a thorough physical examination and screening for renal and cardiac abnormalities in all patients presenting with Duane's reaction syndrome.

Abstract
PURPOSE To investigate CHN1 (chimerin 1) gene mutations in patients with isolated nonsyndromic Duane syndrome and accompanying positive familial history, bilaterality, or various systemic disorders. METHODS Patients with Duane retraction syndrome (DRS) and a positive family history of congenital ocular motility disturbance or bilateral involvement or accompanying any congenital disorder(s) seen consecutively at a single center from 2013 to 2016 were enrolled. All subjects underwent full ophthalmologic examination, including refraction, best-corrected visual acuity, ocular alignment and motility, globe retraction, and biomicroscopic or fundus evaluation. DNA samples were investigated by direct sequencing of the coding regions of the CHN1 gene. RESULTS A total of 30 patients (15 males) were included (mean age, 11.8 ± 10.4 years; range, 2-45 years): 8 cases presented with bilateral DRS; 22, with unilateral DRS. Family history of ocular motility abnormality was positive in 16 patients. Eleven cases had an additional congenital disorder. In 2 patients, 2 different mutations were detected in the CHN1 gene: p.E313K (c.937G>A) and p.N224S (c.671A>G). CONCLUSIONS CHN1 mutations were identified in 2 bilateral cases and in 1 parent of 1 affected case. One mutation is novel and occurred with additional vertical gaze abnormalities. Additional genetic studies evaluating chimerin 1 (CHN1) and its role in the development of the ocular motor axis are needed to provide new data about these mutations and phenotypic variations.

Abstract
Duane retraction syndrome (DRS) is a congenital eye movement anomaly characterized by variable horizontal duction deficits, with narrowing of the palpebral fissure and globe retraction on attempted adduction, occasionally accompanied by upshoot or down-shoot. The etiopathogenesis of this condition can be explained by a spectrum of mechanical, innervational, neurologic and genetic abnormalities occurring independently or which influence each other giving rise to patterns of clinical presentations along with a complex set of ocular and systemic anomalies. Huber type I DRS is the most common form of DRS with an earlier presentation, while Huber type II is the least common presentation. Usually, patients with unilateral type I Duane syndrome have esotropia more frequently than exotropia, those with type II have exotropia and those with type III have esotropia and exotropia occurring equally common. Cases of bilateral DRS may have variable presentation depending upon the type of presentation in each eye. As regards its management, DRS classification based on primary position deviation as esotropic, exotropic or orthotropic is more relevant than Huber’s classification before planning surgery. Surgical approach to these patients is challenging and must be individualized based on the amount of ocular deviation, abnormal head position, associated globe retraction and overshoots.

Abstract
Purpose Surgical treatment in Duane retraction syndrome (DRS) can be very challenging even for the strabismus specialists because of a wide spectrum of diversity in clinical manifestations. The purpose of this article is to review these different surgical treatments. Methods A comprehensive search was performed using PubMed database with the different keywords of "Duane retraction syndrome" and "surgery". Articles were selected from original English papers published since 2000. The full text of the selected articles was reviewed, and some articles were added based upon the references of the initial articles. We also provided selected case examples about some of these procedures. Results 125 articles were found in the initial search of which 37 articles were mostly related to the topic of this review. The number finally increased to 59 articles after considering the relative references of the initial articles. Different surgical methods performed on horizontal and vertical rectus muscles (recession, resection, transposition, Y splitting, periosteal fixation and posterior fixation suture) are reviewed. Careful selection of the surgical technique is important to achieve optimal results. Conclusion With accurate diagnosis of patients with DRS and proper surgical management, several adverse situations associated with this syndrome (amblyopia, abnormal head posture, upshoot, downshoot, and muscle underaction) can be prevented.

Abstract
INTRODUCTION Congenital Brown syndrome and Stilling-Duane syndrome, two rare causes of strabismus are caused by fibrosis of one or more extraocular muscles. This series aims to report the clinical sensory and motor features of patients with Brown or Stilling-Duane syndrome. METHODS Seventeen patients' records were retrospectively assessed for: the ocular deviation in primary position and in the 9 positions of gaze, head tilt, visual acuity and binocular vision. RESULTS Eleven patients with Stilling-Duane syndrome had a mean age of 12 years, and monocular involvement, most frequently of type I. The ocular deviation was variable; 16 patients had an abnormal head position, while 50 % presented with amblyopia, and only 37 % achieved fusion in the compensatory head posture. Six patients presented with congenital Brown syndrome at mean age of 6 years. Three had a moderate form, 3 had a severe form with vertical deviation in primary position, compensatory head position, amblyopia and binocular vision impairment. DISCUSSION The motility impairments depend highly on the identified syndrome, its classification and its severity. Therefore, these two retraction syndromes present some common features. Strabismus in primary position may lead to amblyopia and binocular vision impairment. CONCLUSION Clinical motility and sensory assessment is essential, though difficult, to establish the diagnosis and the management of patients with retraction syndromes.

Abstract
PURPOSE To report the results of using prismatic glasses for Duane retraction syndrome (DRS). METHODS Data were obtained from the records of patients who were evaluated during the year 2000 in the Strabismus Unit of the Beyoglu Eye Training and Research Hospital. The average follow-up was 12.2±17.7 months. In all cases, 2 main variables were evaluated: horizontal deviation in the primary position and face turn. Prismatic glasses were provided to patients according to the degree of shift in the primary position. RESULTS The mean age of patients was 11.2 years. An analysis was performed on the data collected from 12 cases; 7 patients were females (58.3%) and 5 were males (41.7%), with 11 (91.7%) cases being of type I DRS. All 12 patients had abnormal head posture (face turn) and an angle of mean deviation equaling 10 PD (prism dioptri). CONCLUSION Treatment was individualized on a case-by-case basis. Prismatic glasses are useful for eliminating abnormal head posture and ocular misalignment in selected cases.

Abstract
PURPOSE To determine the prevalence and clinical characteristics of patients with Duane retraction syndrome presenting with exotropia in a tertiary eye care center. METHODS Medical records of 140 patients with Duane retraction syndrome and exotropia (of the total 441 patients with Duane retraction syndrome) seen from 2000 to 2009 were reviewed. Characteristics studied included age at presentation, gender, laterality, manifest primary position, abnormal head posture, ocular motility, and overshoots. Data were collected regarding associated ocular or systemic abnormalities and amblyopia. RESULTS The mean age of the patients at presentation was 16.96 ± 15.09 years (range: 1 to 70 years). Of the 140 patients with Duane retraction syndrome and exotropia, 59 (42%) were male. Unilateral type I Duane retraction syndrome accounted for 118 (84.2%), type II for 7 (5%), and type III for 10 (7.1%) patients, whereas 5 (3.6%) had Duane retraction syndrome and bilateral exotropia. Duane retraction syndrome was seen in the left eye, right eye, and both eyes in 97 (69%), 37 (26%), and 6 (4%) patients, respectively. Exotropia ranged from 10 to 60 prism diopters. An abnormal head posture was noted in 101 (72%) and upshoot in 26 (18.6%) patients. Reported ocular and systemic abnormalities in these patients included cataract (6), aniridia (1), nasolacrimal duct block (1), and retinal breaks (1). CONCLUSIONS This is an exclusive study on a large series of patients with Duane retraction syndrome and exotropia. Almost one-third of patients with Duane retraction syndrome patients might have exotropia. Although patients with Duane retraction syndrome and exotropia had clinical characteristics and associations similar to those with Duane retraction syndrome and esotropia, there was an increased propensity for overshoots and face turn opposite to the affected eye, which the authors hypothesize to be due to a tight or short lateral rectus muscle.

Abstract
Congenital ptosis is a rare condition characterized by lower positioning of the upper eyelid that is present at birth and is a clinical condition that is persistent if not treated. It may be unilateral or bilateral and may be associated with other ocular disorders or systemic conditions, including Marcus Gunn, Horner, and Duane syndromes. It is a benign condition but causes functional, cosmetic, and psychological problems in children. However, not all patients need to undergo surgery, and usually only patients at risk of amblyopia need a prompt surgical correction, while in other cases, surgery can be postponed. The grade of ptosis, the eyelid function, and the amblyopic risk are the parameters that affect the ophthalmologist’s decision on timing of surgery and the surgical technique to be used. In fact, there are several types of surgical techniques to correct a congenital ptosis, although very often more than one is needed to obtain an acceptable result. This paper reviews the causes of congenital ptosis and associated diseases. Particular emphasis is given to surgical management and different procedures available to correct the upper eyelid anomaly and avoid permanent damage to visual function.

Abstract
Duane syndrome (DS) is a common form of congenital cranial dysinnervation disorders. The ocular motility pattern lies in a wide clinical spectrum, and the choice of treatment must be individualized depending on the severity of the clinical findings. There is no perfect method of treatment and no real “cure” in DS. In this paper, the aim is to give some guidelines to the reader for selection of the most appropriate treatment method for the patient.

Abstract
PURPOSE To evaluate the efficacy of botulinum toxin injection in the patients with type 1 Duane syndrome and identify the predictive factors for success. METHODS Sixteen patients with esotropic type 1 Duane syndrome without history of ocular surgery were selected for this interventional case series. The botulinum toxin was injected in the medial rectus of all patients. Visual acuity, dry refraction, cyclo-refraction, ocular motility, and amount of deviation were measured. Complete success, partial success, and failure were defined as residual deviation/face turn less than 8 prism diopters (PD)/5°, 8-20 PD/5-15°, and equal or greater than 20 PD/15°, respectively. RESULTS Sixteen cases (6 males) were included in our study. The mean esotropia was 26.27 ± 8.35 (12-40 PD) which was reduced significantly to 13.5 ± 12.39 PD during 6 months follow-up (p < 0.001). Face turn was improved significantly from a preoperative mean of 18.27° to: 0.094° at 1 week, 0.11° at 1 month, 3.31° at 3 months, and 7° at 6 months (p < 0.001). Complete success was seen in 6 patients (37.5%), partial success in 4 patients (25%), and failure in 6 patients (37.5%). There was a significant relation between the amount of forced duction testing (FDT) and the success rate (p: 0.019). No complication was seen during injections. CONCLUSIONS Botulinum toxin could be an alternative treatment in Duane syndrome with appropriate case selection. FDT could be a predictive factor for response to botulinum toxin.

Abstract
PURPOSE To assess the importance of monogenic mutations and chromosomal copy number variants (CNVs) in the occurrence of nonsyndromic bilateral Duane retraction syndrome (bilateral nsDRS). METHODS The medical records of 12 patients with bilateral nsDRS were reviewed. Genes associated with DRS and associated congenital cranial dysinnervation disorders (SALL4, CHN1, HOXA1, TUBB3, and KIF21A) were sequenced in the standard fashion in each patient. Array comparative genomic hybridization (array CGH) was performed using Affymetrix Cytogenetics Whole-Genome 2.7M array, and the results were analyzed using Affymetrix Chromosome Analysis Suite v1.2. CNVs were assessed as unlikely to be pathologic if they were also present in the Database of Genomic Variants (DGV) or our local database of array CGH results in 150 normal individuals of Middle Eastern ethnicity. RESULTS No patient had a sequence mutation in SALL4, CHN1, HOXA1, TUBB3, or KIF21A. These 12 patients each had 36-42 chromosomal deletions and/or duplications (mean with standard deviation, 26.25 ± 6.77), but all of these CNVs were present either in the DGV or in our local database of normal individuals of similar ethnicity and, therefore, are considered nonpathogenic. CONCLUSIONS The results reported here suggest that bilateral nsDRS is not usually associated with mutations in these genes or with chromosomal CNVs. Current evidence suggests other factors such as epigenetic and/or teratogenic abnormalities may be a potential cause of bilateral nsDRS.

Abstract
Duane's retraction syndrome (DRS) is characterized by limitations in horizontal eye movements, globe retraction, and palpebral fissure narrowing on attempted adduction. This disorder is caused by a disturbance in innervation originating in the brain stem and represents <1% of all cases of strabismus. It is postulated that this syndrome is due to an insult during the early weeks (8-10 weeks) of pregnancy and is 10-20 times more frequently associated with other systemic congenital anomalies. This case report of bilateral DRS included bilateral iris-retinal coloboma and congenital heart disease, sensory hearing loss, and inguinal hernia.

Abstract
OBJECTIVE To further define the clinical features of Duane syndrome and analyze the surgical outcomes in a subset of these patients. DESIGN Retrospective chart review. PARTICIPANTS A retrospective chart review of 75 patients with Duane syndrome was performed. METHODS Complete ophthalmologic and orthoptic data were extracted from the patients' charts, and patients were classified into group I, II, or III based on forced primary position (PP) deviation. Eighteen patients had strabismus surgery to correct the ocular misalignment with its related abnormal head posture. RESULTS Fifty-six percent of the cases were in group I, 16% in group II, and 28% in group III. Fifty-seven percent were female, 91% were unilateral, and 66% had left eye involvement. Ninety-six percent had fissure-narrowing/globe retraction on adduction; 67% had an upshoot, downshoot, or both; and 63% had an A, V, or X pattern. The A patterns correlated with downshoots in 100% of cases, V patterns with upshoots in 88%, and X patterns with upshoots/downshoots in 100%. In the 18 surgical candidates, there were 14 patients in group I, 4 in group II, and 0 in group III. An excellent surgical outcome occurred in 78% of patients and a fair-to-poor outcome in 22%. Upshoots/downshoots and fissure-narrowing/globe retraction patients showed modest improvement after surgery. CONCLUSIONS There was a consistent relationship among the type of strabismus, head position, and motility defect. The type of upshoot/downshoot correlated strongly with the A, V, or X pattern. Postoperative improvements of abnormal head posture and PP alignment were achieved in the surgical subset of patients.

Abstract
Purpose To compare the results of 2 surgical procedures in the management of vertical shooting in exotropic Duane retraction syndrome (XT-DRS). Methods This was a prospective, interventional study of consecutive patients with XT-DRS with vertical shooting on adduction operated on from August 2012 to January 2015. A total of 25 patients were identified and were divided into 2 groups: the Y-split (Y) group, which included 12 patients, who underwent Y-splitting with recession of the lateral rectus muscle (LR); and the isolated recession (R) group, which included 13 patients, who underwent isolated LR recession. Surgical outcomes in both groups were compared in terms of improvements in vertical shoots, ocular deviation, and face turn. Results Upshoot, downshoot, XT, and face turn showed significant postoperative improvement in both groups (p<0.001). When comparing the groups, the difference in the average correction of the upshoot and downshoot was statistically significant ( p = 0.0004 and 0.0174, respectively) in benefit of the Y-group. One case of horizontal overcorrection (consecutive esotropia) with another case of horizontal undercorrection (persistent XT) were reported postoperatively in the Y-group. Conclusions In our series, both procedures achieved comparable results in the correction of XT and face turn. The combined Y-split recession procedure attained a more significant improvement of upshoot and downshoot but with higher incidence of postoperative complications.

Abstract
PURPOSE Duane syndrome (DS) belongs to a group of congenital retraction syndromes, the incidence of which varies between 2% and 4% in patients with strabismus. In most cases the damage is unilateral, but it manifests as bilateral in about 20% of cases. According to the classification of Huber, type III DS exhibits a limitation of abduction and adduction. METHODS We report the case of a 5-year-old boy from Eastern Europe who was taken to the hospital because he was unable to move both eyes horizontally from birth and had not been previously seen by an ophthalmologist. RESULTS The examination showed inability to abduct and adduct bilaterally, with narrowing of the palpebral fissures on attempted adduction. The patient was diagnosed with bilateral type III DS. CONCLUSIONS Treatment is individualized on a case-by-case basis. For our patient, monitoring by way of regular checkups was chosen, with the parents rejecting surgery for now.

Abstract
A 5-year-old girl presented with bilateral familial vertical Duane retraction syndrome with alternating esotropia, elevation deficit, Marcus gunn phenomenon, and facial hypoplasia. Abnormal adducting downshoots on attempting abduction suggestive of a synergistic convergence were noted. Hypothesis suggests aberrant innervations or peripheral anatomic connections between inferior and medial recti.
