Coexistence of Idiopathic Intracranial Hypertension with Unilateral Duane Retraction Syndrome Type 1 in an Adult Female.

Case Rep Ophthalmol 2022 Jan-Apr;13(1):292-296. Epub 2022 Apr 22.

Department of Ophthalmology, College of Medicine, King Saud University, Riyadh, Saudi Arabia.

Idiopathic intracranial hypertension (IIH) is a poorly understood condition, and its presentation can coexist with other diseases. Simultaneous IIH and Duane retraction syndrome (DRS) type 1 have never been reported to coexist in an adult patient. Herein, we report a 32-year-old obese female with a history of chronic renal failure who had a renal transplant rejection 6 years prior to presentation and was treated with oral steroids and immunosuppressive medications.

Superior Rectus Transposition in the Management of Duane Retraction Syndrome: Current Insights.

Clin Ophthalmol 2022 26;16:201-212. Epub 2022 Jan 26.

Jasti V Ramanamma Children's Eye Care Centre, Child Sight Institute, L V Prasad Eye Institute, Hyderabad, India.

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. Read More

The Rac-GAP alpha2-Chimaerin Signals via CRMP2 and Stathmins in the Development of the Ocular Motor System.

J Neurosci 2021 08 24;41(31):6652-6672. Epub 2021 Jun 24.

School of Life Sciences, University of Sussex, Brighton BN7 9QG, United Kingdom

A precise sequence of axon guidance events is required for the development of the ocular motor system. Three cranial nerves grow toward, and connect with, six extraocular muscles in a stereotyped pattern, to control eye movements. The signaling protein alpha2-chimaerin (α2-CHN) plays a pivotal role in the formation of the ocular motor system; mutations in , encoding α2-CHN, cause the human eye movement disorder Duane Retraction Syndrome (DRS).

Nephron 2021 11;145(4):445-450. Epub 2021 May 11.

Department of Nephrology, Osaka University Graduate School of Medicine, Suita, Japan.

The MAFB gene encodes an important basic leucine zipper transcription factor that functions in glomerular podocytes, macrophages, and osteoclasts. Recently, MAFB was identified as the gene that was responsible for causing nephropathy with focal segmental glomerulosclerosis (FSGS) with multicentric carpotarsal osteolysis (MCTO) or Duane retraction syndrome (DRS). Here, we describe a patient with nephropathy associated with FSGS who exhibited a novel stop-gain variant in the MAFB gene (NM_005461:c. Read More

CHN1 and duane retraction syndrome: Expanding the phenotype to cranial nerves development disease.

Eur J Med Genet 2021 Apr 2;64(4):104188. Epub 2021 Mar 2.

Service de Génétique Médicale, Centre Hospitalier Universitaire de Bordeaux, Bordeaux, France; MRGM, Maladies Rares: Génétique et Métabolisme, lNSERM U1211, Université de Bordeaux, Bordeaux, France.

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.

Orbital myositis is a rare, commonly idiopathic, inflammatory condition that affects one or more extraocular muscles. We present a case of unilateral orbital myositis affecting the lateral rectus muscle presenting with gaze-evoked amaurosis, pain, and diplopia, with restrictive limitation of adduction. With improvement in adduction after initiating treatment, we noted narrowing of the palpebral fissure on attempted adduction, mimicking Duane retraction syndrome (DRS). Read More

Department of Ophthalmology and Laboratory for Visual Science, National Center for Child Health and Development, Tokyo, Japan.

CDK9 has been considered a candidate gene involved in the CHARGE-like syndrome in a pair of cousins. We report an 8-year-old boy with a strikingly similar phenotype including facial asymmetry, microtia with preauricular tags and bilateral hearing loss, cleft lip and palate, cardiac dysrhythmia, and undescended testes.
