To investigate whether ocular albinism type 1 (OA1) is differentially expressed in the skin of mice with different coat colors and to determine its correlation with coat color establishment in mouse, the expression patterns and tissue distribution characterization of OA1 in the skin of mice with different coat colors were qualitatively and quantitatively analyzed by real-time quantitative PCR (qRT-PCR), immunofluorescence staining and Western blot. The qRT-PCR analysis revealed that OA1 mRNA was expressed in all mice skin samples tested, with the highest expression level in brown skin, a moderate expression level in black skin and the lowest expression level in gray skin...

PURPOSE: To compare surgical results of augmented and nonaugmented modified Knapp procedure, for the treatment of nonrestrictive double elevator palsies (DEP). METHODS: The medical records of patients with congenital DEP were reviewed retrospectively. Patients were divided into three treatment groups: standard transposition (group A), Foster transposition (group B), and resection transposition (group C). Pre- and postoperative vertical deviation in primary position, ocular motility, and binocular vision were compared...

PURPOSE: To discuss surgical intervention strategies and innervation among patients with horizontal gaze palsy with concurrent esotropia. METHODS: Five consecutive patients with dorsal pontine lesions are presented. Each patient had horizontal gaze palsy with symptomatic diplopia as a consequence of esotropia in attempted primary gaze and an anomalous head turn to attain single binocular vision. RESULTS: Clinical findings in the first 2 patients led us to presume there was complete loss of rectus muscle function from rectus muscle palsy...

The aim of this study was to compare the effectiveness of porous polyethylene, titanium mesh, and castor oil-derived biopolymer randomized in orbital reconstructions of defects larger than 1 cm in length on the inferior and medial walls. A total of 63 patients (64 orbits) were evaluated to determine the presence of diplopia, enophthalmos ocular motility, and infraorbital nerve paraesthesia in both the preoperative and postoperative periods. The surgeons' opinions of the ease in handling the implants were also obtained after each procedure...

In the treatment of severe oculo-orbital traumas, intraocular malignancies or other life-threatening conditions it is sometimes necessary to surgically remove the patient's diseased eye. Following the removal of the eye, an orbital implant is inserted into the anophthalmic socket in order to provide satisfactory volume replacement and restore the aesthetic appearance of a normal eye. Over the last decades, the implant design and the criteria of materials selection evolved from simple non-porous polymeric sphere to devices with more complex shape and functionalities for ensuring better clinical outcomes in the long-term...

PURPOSE: To report 4 cases of Marcus Gunn jaw-winking synkinesis (MGJWS) in the absence of ptosis. METHODS: A retrospective review of patients with MGJWS and congenital ptosis was compiled from the public and private subspecialty adult and pediatric oculoplastic practices of the 2 senior authors (AAM, TGH). Clinical data collected on patients with MGJWS included visual acuity, stereopsis, ocular motility, side of jaw-wink, presence or absence of ptosis, levator function, clinical photographs and videos, and any management undertaken...

The case example presented shows that an orbital emphysema with exophthalmos can occur as a rare complication of a transconjunctival pars plana vitrectomy. Close monitoring of the patient symptoms, ocular motility, intraocular pressure and the fundus showed no evidence of compressive optic neuropathy or perfusion abnormalities through orbital vessels. The exophthalmos resolved spontaneously within a few days without any consequences.

OBJECTIVE: The aim of this study was to investigate the fractional anisotropy (FA) and mean diffusivity (MD) using a diffusion tensor imaging technique and whole-brain voxel-based analysis in patients with comitant strabismus. PATIENTS AND METHODS: A total of 19 (nine males and ten females) patients with comitant strabismus and 19 age-, sex-, and education-matched healthy controls (HCs) underwent magnetic resonance imaging examination. Imaging data were analyzed using two-sample t-tests to identify group differences in FA and MD values...

OBJECTIVE: To investigate the effect of superior oblique tucking on the Bielschowsky head tilt test. METHODS: A retrospective analysis of 22 patients with congenital unilateral superior oblique palsy, who underwent tucking of the superior oblique tendon in Tianjin Eye Hospital, depending on vertical deviation in the primary position, ocular motility, objective cyclotorsion and abnormal head posture. Bielschowsky head tilt test was evaluated quantitatively by the prism cover test...

OBJECTIVE: To investigate the effect and safety of the graduated "hang-back" recession of superior oblique (SO) in treatment of A-pattern strabismus with superior oblique overaction (SOOA). METHODS: Retrospective study. The clinical data of 15 cases (28 eyes), who underwent graduated "hang-back" recession of SO depending on the scales of SOOA, were collected and analyzed. The principle we carried on was hang-back recession 8-10mm for SOOA+4, 6 to 8 mm for SOOA+3, 5 to 6 mm for SOOA+2 and 4 mm for SOOA+1...

PURPOSE: To study the binocular alignment and ocular motility in patients with large-angle esotropia due to sixth nerve palsy treated with double augmented vertical recti transposition. METHODS: This was a prospective interventional study. Fifteen patients with non-resolving sixth nerve palsy who underwent surgical correction were included in the study. Fourteen patients also underwent an additional medial rectus recession. Two patients with an associated small vertical deviation had a selective augmentation of one vertical rectus muscle...

Congenital fibrosis of the extraocular muscles (CFEOM) is a hereditary ocular disease and can be classified into three subtypes. The aim of the present study was to determine the genetic basis and describe the clinical phenotype of CFEOM type 1 and 3. Two Chinese families with CFEOM type 1 and 3 were identified. The patients and their family members were subjected to comprehensive ophthalmic examinations, including best‑corrected visual acuity, slit‑lamp examination, fundus examination, assessment of palpebral fissure size, levator function, ocular motility, and cover and forced duction tests...

Orbital Apex Syndrome (OAS) is a rare complication of Herpes Zoster Ophthalmicus (HZO). We are reporting a case of 65-year-old male who developed OAS following HZO. Patient presented with vesicular rash in the typical dermatomal distribution, severe periocular congestion and limited ocular motility in all gazes along with loss of vision. Soft tissue inflammation improved within 4 weeks of initiation of treatment while ocular motility slowly improved over 3 months. Patient did not gain vision despite receiving systemic steroids and systemic anti-viral medication...

OBJECTIVES: This case report looks at a 53-year-old patient who had suffered a penetrating foreign body injury to the retro-orbital space and the surgical approach taken to remove the large glass fragments found and to correct the damage caused. Having fallen while holding a drinking glass, this patient suffered multiple laceration injuries to the maxillofacial region upon the glass shattering in contact with the face. However, unbeknownst to the patient, several glass fragments became embedded in the retro-orbital space, and this was only detected on presentation 2 days post-injury with unusual symptoms of sharp, sudden pain elicited on extreme gaze as well as ocular motility restriction...

A 48-year-old smoker with a history of hyperthyroidism treated 10 years prior to presentation with radioactive iodine ablation of the thyroid gland presented to his ophthalmologist with a 2-week history of transient loss of vision in the right eye occurring for 1 to 2 hours each morning. He denied ocular pain, diplopia or change in the prominence of one or both eyes. Examination revealed 2 mm of relative proptosis on the right, bilateral temporal flare and lower lid retraction. There was minimal upper lid retraction and no evidence of lid lag...

PurposeTo identify factors associated with stereopsis in children with good visual acuity after unilateral congenital cataract surgery in the Infant Aphakia Treatment Study.Patients and methodsInfants with a unilateral congenital cataract (n=114) were randomized to IOL implantation or contact lens correction after cataract surgery. At age 4.5 years, a masked examiner assessed HOTV acuity and stereopsis. Adherence to patching was assessed using 48-h recall telephone interviews and 7-day diaries throughout the first 5 years of life...
