PURPOSE OF REVIEW: To review current knowledge regarding diagnosis of nonthyroid orbital disorders with extraocular muscle enlargement. RECENT FINDINGS: Recent publications have focused on immunoglobulin G4-related disease as a possible cause of enlarged extraocular muscles, on patterns of strabismus that raise a clinical suspicion of intramuscular lymphoma, and on surgical techniques to access the muscles for tissue biopsy. SUMMARY: With enlarged extraocular muscles, features to distinguish between competing diagnostic possibilities are based on imaging in the context of history and clinical signs...

Disrupting binocular vision in infancy leads to strabismus and oftentimes to a variety of associated visual sensory deficits and oculomotor abnormalities. Investigation of this disorder has been aided by the development of various animal models, each of which has advantages and disadvantages. In comparison to studies of binocular visual responses in cortical structures, investigations of neural oculomotor structures that mediate the misalignment and abnormalities of eye movements have been more recent, and these studies have shown that different brain areas are intimately involved in driving several aspects of the strabismic condition, including horizontal misalignment, dissociated deviations, A and V patterns of strabismus, disconjugate eye movements, nystagmus, and fixation switch...

RATIONALE: The CTNNB1 (β-catenin) gene is well known for its crucial role in cell adhesion and the Wnt-signaling pathway. Previous studies have shown that gain-of-function mutations in the CTNNB1 gene contribute to the occurrence and development of a variety of carcinomas in humans. Recently, de novo, heterozygous, loss-of-function mutations of the CTNNB1 gene were found that partially explain intellectual disability in some patients. Other major clinical symptoms in these patients included microcephaly, abnormal facial features, motor delays, speech impairments, and deformities of the hands and feet...
