1/82. Familial Duane's retraction syndrome.

    BACKGROUND: Duane's retraction syndrome (DRS) has been described as a clinical entity for more than a century. Although the majority of cases occur spontaneously, some cases of DRS are inherited. case reports: A young Romanian boy with a known left abduction deficit was determined to have DRS. On thorough examination of other family members, it was discovered that his younger brother and father also had the syndrome. Clinical findings of the affected family members are described. RESULTS: All three family members showed left esotropia in primary gaze, along with a compromised ability to turn the left eye outward. They also demonstrated an anomalous head turn to the left, and mild narrowing of the palpebral fissure and retraction of the globe on adduction. These are all classic signs of unilateral DRS. CONCLUSION: These findings provide further evidence of an autosomal dominant mode of inheritance in some cases of DRS.

2/82. Recession of both horizontal rectus muscles in Duane syndrome with globe retraction in primary position.

    INTRODUCTION: Duane syndrome is characterized by abduction deficiency, narrowing of the palpebral fissure on adduction, and globe retraction,which can be the most prominent aspect of the motility disorder. Recession of both horizontal rectus muscles was investigated for treatment of severe globe retraction. methods: Three patients with Duane syndrome were operated on for severe globe retraction. The medial rectus muscles were recessed from between 5.5 to 6.5 mm and the lateral rectus muscles 7.0 to 9.0 mm simultaneously. The recessions were asymmetric, as evidenced by amount of esotropia and face turn. Preoperative Hertel measurements were made in primary gaze, 30-degree left gaze, and 30-degree right gaze. The measurements were repeated at 6 months and 1 year after the operation. RESULTS: All three patients had improvement in globe retraction. The 6-month Hertel readings in primary position were improved by a mean of 3.0 mm (range 2.5 to 3.5 mm) measured in primary gaze. Hertel measurements were stable at 1 year after the operation. No complications were encountered. CONCLUSIONS: Recession of both horizontal rectus muscles is effective in the treatment of significant globe retraction in Duane syndrome.

3/82. A case of congenital inverse Duane's retraction syndrome.

    Inverse Duane's retraction syndrome is very uncommon. Congenital cases are even more unusual. A 6-year-old girl with convergent squint along with severe restriction on abduction is described. On attempted abduction, a narrowing of the palpebral fissure, upshoot and retraction of the eyeball were observed. brain and orbit MRI demonstrated no intracranial or intraorbital mass, fracture, or entrapment of the medial rectus. Forced duction test was strongly positive. The primary lesion was found to be a tight medial rectus with shortening and soft tissue contracture. Surgical tenotomy of the medial rectus led to successful postoperative motility, but some limitation at full adduction and abduction persisted. This is a case reported with congenital medial rectus shortening, suggesting that this condition may be one of the etiologies of the rare inverse Duane's retraction syndrome.

4/82. duane retraction syndrome, a new feature in 22q11 deletion syndrome?

    A female child with duane retraction syndrome is described. A microdeletion on chromosome 22(q11) was discovered using FISH analysis. It is postulated that duane retraction syndrome might be a new feature in 22q11 deletion syndrome.

5/82. A patient with de Morsier and Duane syndromes.

    de Morsier syndrome, or septo-optic dysplasia, is a developmental malformation complex characterized by optic nerve hypoplasia, dysgenesis of the septum pellucidum, and hypothalamic-pituitary dysfunction. (1,2) In duane retraction syndrome, there is absence of the sixth nerve nucleus with congenital retraction of the globe and narrowing of the lid fissure in adduction, frequent abduction deficiency, and variable limitation to adduction of the affected eye. (3) The purpose of this report is to present a patient with the uncommon and previously unreported concurrence of both of these congenital malformation complexes, presumably because of a common disturbance of neuronal development.

6/82. Duane's retraction syndrome: literature review.

    BACKGROUND: Duane's retraction syndrome (DRS), also known as Stilling-Turk-Duane syndrome, is defined as a congenital miswiring of the lateral and medial recti muscles, resulting in an impaired ocular motility syndrome that includes palpebral fissure narrowing. The incidence of DRS is approximately 1% of the total cases of strabismus. Eighty percent of cases are unilateral and characterized by either limited abduction, limited adduction, or both. CASE REPORT: A 21-year-old man came to the clinic for a routine ocular examination without symptoms. A review of the history uncovered the presence of congenital, type I Duane's retraction syndrome. The examination demonstrated orthophoria in primary gaze, an abduction deficit O.S., and left globe retraction with palpebral fissure narrowing on right gaze O.S. MANAGEMENT: In most cases of DRS the eyes are straight in primary position and there is no amblyopia. amblyopia, when present, is usually the result of anisometropia and not strabismus. Because our patient had no symptoms of diplopia in primary gaze (orthophoria) or in attempted right gaze (due to suppression of the left eye with abduction), prismatic and/or surgical management were not indicated, since the patient was free from binocular and cosmetic abnormalities. CONCLUSION: DRS is characterized by abnormal development of the cells in the abducens nucleus (CN VI), resulting in restricted or absent abduction and erroneous innervation of the lateral rectus by branches emanating from oculomotor nuclei (CN III). Management may include orthoptics, surgery, or monitoring.

7/82. Bilateral Duane syndrome with bilateral congenital glaucoma.

    Multiple ocular associations with Duane syndrome have been reported as summarized by DeRespinis et al. The most frequently noted include nystagmus, anisocoria, ptosis, optic nerve colobomas, and epibulbar dermoids. Less encountered abnormalities are optic nerve hypoplasia, heterochromia, and congenital cataract. To our knowledge, no reports of associated congenital glaucoma exist in the literature. We report a 10-year-old patient with bilateral Duane syndrome and bilateral congenital glaucoma who we have monitored for 7 months after birth.

8/82. Pseudo-entrapment of extraocular muscles in patients with orbital fractures.

    diplopia is a prominent finding in patients who have suffered orbital fractures. If the patient's double vision or ocular motility restriction was caused by soft tissue entrapment into the fracture site, surgery is frequently performed in order to release this entrapment and restore normal eye movement. However, the presence of diplopia should not necessarily be an indication for surgery. Brief case reports are hereby presented to illustrate that the symptoms of diplopia and motility restriction are not always attributable to the presence of orbital fractures that require surgical repair. The purpose of this article is to describe other causes of abnormal ocular motility that are associated with orbital trauma but which are not caused by soft tissue entrapment.

9/82. A case of congenital oblique retraction syndrome with upshoot in adduction.

    We treated a 27-year-old man who suffered from a congenital eye movement abnormality. The patient could not adduct the left eye, and showed exotropia, hypertropia and excyclotropia of the left eye. The range of abduction was also limited. The left eye showed marked upshoot on right gaze and eye globe retraction on right down gaze under conditions of right-eye viewing. The superior rectus muscle of the left eye was recessed and transposed nasally. The insertion of the superior oblique muscle was found to be defective. The upshoot and face turn improved after surgery. The globe retraction on right down gaze was no longer evident. We believe that the superior rectus muscle was innervated by an anomalous branch of the oculomotor nerve, which was originally destined to innervate the medial rectus, and that simultaneous contraction of the superior and inferior rectus muscles caused the globe retraction on right down gaze. This case also suggests the possibility that some part of the upshoot in adduction in Duane's syndrome is due to the co-contraction of the superior and medial rectus muscles due to this innervation anomaly.
