A man aged 51 years presented with sudden onset, horizontal, binocular, double vision and right facial weakness. Ocular motility examination demonstrated a right horizontal gaze palsy pattern in keeping with a one-and-a-half syndrome. Since this was associated with a concomitant, ipsilateral, lower motor neuron (LMN) facial (VIIth) cranial nerve palsy, he had acquired an eight-and-a-half syndrome. Diffusion-weighted MRI confirmed a small infarcted area in the pons of the brainstem which correlated with anatomical location of the horizontal gaze centre and VIIth cranial nerve fasciculus...

BACKGROUND: Traditional orthoptic therapy used by ophthalmologists, orthoptists, and optometrists is directed at improving visual acuity, ocular alignment, or both. For example, convergence exercises are used to treat convergence insufficiency (CI). However, other forms of "vision therapy" are directed at improving "visual processing and efficiency." The therapeutic regimen often entails repetitive ocular motor tasks performed during multiple office visits with a behavioral optometrist...

REVIEW
John K Chilton, Sarah Guthrie
Cranial nerves innervate head muscles in a well-characterised and highly conserved pattern. Identification of genes responsible for human congenital disorders of these nerves, combined with the analysis of their role in axonal development in animal models has advanced understanding of how neuromuscular connectivity is established. Here we focus on the ocular motor system, as an instructive example of the success of this approach in unravelling the aetiology of human strabismus. The discovery that ocular motility disorders can arise from mutations in transcription factors, including HoxA1, HoxB1, MafB, Phox2A and Sall4, has revealed gene regulatory networks that pattern the brainstem and/or govern the differentiation of cranial motor neurons...

Jinyong Cho, Jaeyoung Ryu
Blow-in fracture of the zygomaticomaxillary complex that was displaced into the orbital cavity could be associated with ophthalmologic injuries, ranging from visual acuity to ocular motility limitation. Appropriate reduction and realignment of the fractured bone is necessary as early as possible for recovery of function and esthetics. However, limitation of accessibility and visibility makes it difficult for delicate surgery and increases the risk of damage of adjacent anatomic structures, such as optic nerve and extraocular muscles...

The aim of this study was to determine the predictive value of a specific computed tomography (CT)-based assessment for the final functional ophthalmological outcome in pure orbital floor blowout fractures. Data of 34 consecutive patients with pure blowout fractures who had undergone a period of at least 6 months of medical and ophthalmological follow-up were analyzed. The following 3 CT scan-based parameters were included: area ratio of the fractured orbital floor (RF), maximum height of periorbital tissue herniation (MH), and a 4-grade muscular subscore (MSS) describing the inferior rectus muscle displacement relative to the orbital floor level...

MIRAgel (MIRA, Waltham, MA) scleral buckle material was initially developed in the 1980s as an alternative to more traditional silicone buckles. Long-term follow-up has demonstrated complications necessitating removal due to unanticipated hydrolytic degeneration of the exoplant. Material expansion and fragmentation have led to pain, limited extraocular motility, ocular masses, infection, and eventual extrusion. Complications occur later than in other materials; most patients need removal an average of 7 years to 13 years after implantation...

Molecules that are necessary for ocular hypersensitivity reactions include the receptors CCR1 and CCR3; CCL7 is a ligand for these receptors. Therefore, we explored the role of CCL7 in mast cell activity and motility in vitro and investigated the requirement for CCL7 in a murine model of IgE-mediated allergic conjunctivitis. For mast cells treated with IgE and Ag, the presence of CCL7 synergistically enhanced degranulation and calcium influx. CCL7 also induced chemotaxis in mast cells. CCL7-deficient bone marrow-derived mast cells showed decreased degranulation following IgE and Ag treatment compared with wild-type bone marrow-derived mast cells, but there was no difference in degranulation when cells were activated via an IgE-independent pathway...

A 23-year-old male with intermittent visual loss in his left eye for 4 months was originally treated as optic neuritis elsewhere. Upon presentation to our hospital (Beijing Tongren Hospital), his left eye visual acuity was reduced to hand motion at face. The left eye ocular motility was limited in upgaze, downgaze, adduction, and abduction. Computed tomography and magnetic resonance imaging revealed lesions in the sphenoid and ethmoid sinuses, orbital apex and carvernous sinus invading adjacent extraocular muscles...

Jennifer Murdock, Preeti J Thyparampil, Michael T Yen
Chronic progressive external ophthalmoplegia (CPEO) is a mitochondrial myopathy with slowly progressive, often symmetric blepharoptosis and limitation of ocular motility in all directions of gaze. The authors present an unusual case of CPEO that initially presented with the unique features of markedly asymmetric facial weakness and the lack of blepharoptosis. However, over the subsequent three decades, the patient developed progressive facial and eyelid dysfunction more consistent with a classical description of CPEO...

BACKGROUND: Pterygium, a growth of the conjunctiva over the cornea, is a progressive disease leading in advanced stages to visual impairment, restriction of ocular motility, chronic inflammation and cosmetic concerns. Surgical removal is the treatment of choice, but recurrence can be a problem. Currently the best surgical option in terms of recurrence is conjunctival autograft. To date the most common surgical methods of attaching conjunctival autografts to the sclera are through suturing or fibrin glue...
