A 17-year-old boy presented with a large exotropia with both eyes fixed in an abduction and upgaze, pupillary involvement since childhood. He had mild optic nerve hypoplasia in the right eye and situs inversus of the retinal vessels in the left optic disc. His ocular motility showed restriction of eye movements in all gazes. He was diagnosed with congenital fibrosis of extraocular muscles, type 2 (CFEOM2) and operated upon in a staged procedure with a satisfactory eye alignment using hang-back sutures in one eye and periosteal fixation in the other...

REVIEW
Seyhan B Özkan
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.

Ala Paduca, Jan Richard Bruenech
The potential role of sensory feedback from human extraocular muscles has been subjected to considerable speculation in the ophthalmic literature. Extraocular muscles pull against a fairly even load and do not initiate a stretch reflex, even when the eyes are directed toward the boundaries of their respective field of action. These unique working conditions and physiological properties have led to the notion that the sensory signal arising from receptors in extraocular muscles differs from the conventional proprioceptive signal arising from their somatic counterparts...

REVIEW
Alaa S Bou Ghannam, Prem S Subramanian
PURPOSE OF REVIEW: Ocular functions can be affected in almost any type of cerebrovascular accident (CVA) creating a burden on the patient and family and limiting functionality. The present review summarizes the different ocular outcomes after stroke, divided into three categories: vision, ocular motility, and visual perception. We also discuss interventions that have been proposed to help restore vision and perception after CVA. RECENT FINDINGS: Interventions that might help expand or compensate for visual field loss and visuospatial neglect include explorative saccade training, prisms, visual restoration therapy (VRT), and transcranial direct current stimulation (tDCS)...

BACKGROUND AND PURPOSE: Early onset exodeviations in systemically and ocularly healthy young children, diagnosed at less than 1 year of age, may be of the constant, "infantile XT" type, or early X(T) type. The onset of common childhood X(T) is not clearly known. The purpose of this lecture is to discuss theories and characteristics of early onset exodeviations, and report on our observations of infantile XT and early X(T) at Children's Eye Care in Michigan. PATIENTS AND METHODS: A retrospective review of 470 cases of childhood exodeviations (ages 6 months to 15 years) were reviewed and met inclusion criteria of no prior surgical treatment, no ocular, CNS or craniofacial disease, and no significant prematurity...

Dear Editor, An 83-year-old woman developed yellow-brownish infiltrates, nodules, and tumors mimicking xanthomas, mostly involving the periorbital and chest area within three months (Figure 1). She had no abnormalities in serum cholesterol or triglycerides levels. A detailed laboratory analysis revealed the presence of mild monoclonal gammopathy with a presence of immunoglobulin G (IgG) kappa light chains; however, according to hematologist consultation, it did not require medical intervention. Imaging assessment and ultrasound examination did not show any specific involvement of internal organs...

Idiopathic intracranial hypertension, otherwise known as primary pseudotumor cerebri syndrome (PTCS), most frequently occurs in obese women of childbearing age. However, children may be affected as well. This review will address recent findings regarding demographics, diagnosis, and treatment of pediatric PTCS. Prepubertal children with primary PTCS have an equal sex distribution and less frequent obesity compared with adult patients. However, female gender and obesity are risk factors for primary PTCS in postpubertal children...

PURPOSE: A very large angle esotropia is characterized by an angle more than 80 prism diopters (pd). A single eye surgery would not correct such a large angle. Supramaximal recessions and resection would lead to restriction of ocular motility. We present a series of 22 patients with large angle esotropia treated with muscle transplantation. METHODS: A total of 22 patients (14 males and 8 females) were included in the study. All the patients had a minimum of 80 base out deviation in primary position...
