BACKGROUND/AIMS: We performed a retrospective analysis to examine clinical results, establish a dose-effect coefficient and analyze the long-term efficacy of tendon elongation with bovine pericardium (Tutopatch®) for surgical correction of severe esotropia, occurring after three-wall orbital decompression for dysthyroid optic neuropathy in patients with Graves' orbitopathy (GO). METHODS: Tendon elongation of the medial rectus muscle (MR) was performed in our institution using an interponate of bovine pericardium in 60 patients (27 underwent unilateral and 33 bilateral surgery)...

PURPOSE: The aim of the study was to determine the risk of anterior segment ischemia (ASI) after simultaneous three rectus muscle surgery. METHODS: A retrospective cohort study was conducted. All patients who underwent simultaneous three rectus muscle surgery from January 2003 to December 2014 were included. Medical records were reviewed for signs of acute ASI in the postoperative period or presence of any late sequelae. Those patients who had pre-existing corneal pathology obscuring visualisation of anterior chamber and iris were excluded...

AIM: To evaluate differences in eye movements during reading in strabismic children and in non-strabismic age-matched children, and to evaluate the potential effect of strabismus surgery on eye movement performance. METHODS: The eye movements of nine strabismic children from 11 to 15 years old were recorded with an eye tracker as they were reading a text under three visual conditions before and six months after eye surgery. The results were compared with those obtained from control groups of non-strabismic age-matched children...

PURPOSE: The purpose of this study is to investigate clinical and histopathologic features of consecutive exotropia. METHODS: Thirty patients with consecutive exotropia and negative forced duction testing underwent unilateral medial rectus resection and advancement. Abnormal scleral attachment (appearance of stretched scar or slipped muscle) was documented and compared with histopathology results. The term "stretched scar" is used when tendon-like scar appears between muscle fibers and scleral attachment...

PURPOSE: Rectus muscle resection in thyroid eye disease (TED) is generally avoided due to the risk of worsening restriction or reactivating inflammation. However, for some patients with large-angle strabismus or diplopia in primary gaze despite maximum recession surgery, rectus muscle resection may be beneficial. We report our surgical experience with rectus muscle resection in the management of vertical strabismus associated with TED. METHODS: Retrospective review of eight patients with TED and vertical diplopia who underwent vertical rectus muscle resection by a single surgeon (IBM) at a tertiary referral centre in Liverpool, UK, from 2001 to 2013...

PURPOSE: To evaluate the role of simultaneous superior rectus (SR) recession and anterior transposition of inferior oblique (ATIO) muscle in patients with traumatically lost inferior rectus (IR) muscle. METHODS: Six patients with history of ocular trauma, followed by sudden onset vertical diplopia along with marked hypertropia (HT) and limitation of depression in abduction in the affected eye suggestive of IR disinsertion, were included in this prospective study...

BACKGROUND: Dissociated vertical deviation (DVD) is commonly measured using a prism and alternate cover test (PACT), but some providers use a prism under cover test (PUCT). The aim of this study was to compare a standardized PUCT measurement with a PACT measurement, for assessing the magnitude of DVD. METHODS: Thirty-six patients with a clinical diagnosis of DVD underwent measurement of the angle of deviation with the PACT, fixing with the habitually fixing eye, and with PUCT, fixing both right and left eyes...

PURPOSE: To compare ocular deviation in the operating room depending on whether the patient is in supine decubitus or seated after single-stage adjustable strabismus surgery under topical anesthesia. MATERIAL AND METHOD: We performed a prospective observational study of 30 patients with horizontal and/or vertical strabismus who underwent single stage adjustable strabismus surgery under topical anesthesia. Both distance and near deviation were evaluated before surgery, during surgery in both positions (seated and supine), and at 1 day, 1 month, and 3 months after surgery...

BACKGROUND/AIMS: Strabismus due to sagging eye syndrome (SES) caused by age-related connective tissue involution is now an established cause of diplopia in older people. High suspicion of the condition results in early recognition, often obviating extensive neurological investigations and enabling surgical correction of the strabismus. METHODS: This retrospective study reviewed surgical results in 93 patients (40 males) of average age 68 ± 12 years, who had small-angle strabismus due to SES, during the 20-year period 1994-2014...

PURPOSE: Besides chiasmal hemidecussation, interhemispheric connections are likely important in human binocularity. The corpus callosum (CC) is the major fiber bundle in the mammalian brain which mostly connects homologous cortical areas in the two hemispheres. Visual interhemispheric connections were found abnormal in strabismic cats. No studies have investigated these pathways in humans with infantile strabismus. METHODS: Diffusion tensor imaging was used in four subjects with infantile esotropia (IE) and nine control subjects with normal binocularity, in order to study interhemispheric fibers in the CC connecting the right and left primary visual cortical areas...

INTRODUCTION: A spherical globe is traditionally assumed, but this study employed magnetic resonance imaging (MRI) to demonstrate frequent occurrence of non-spherical staphylomata in strabismic patients. METHODS: High-resolution, surface coil MRI was obtained in multiple image planes in 21 highly myopic subjects (36 eyes) and compared with 17 normal controls (33 eyes). Images were analyzed for axial length, aspect ratio of eye shape, and deflection of muscle paths...

PURPOSE: The optimal management of infantile nystagmus syndrome (INS) is still unclear. Contact lenses (CL) may be superior to glasses in improving visual function in INS but it is not known whether their beneficial effects are due to optical correction alone, or to an additional proprioceptive effect, and whether soft CLs would be as effective as rigid CLs. There is little data on feasibility and and the present study aimed to provide this information. METHODS: We completed a pilot Randomized Control Trial (RCT) at a single tertiary referral centre in London, UK...

The use of a conjunctival retractor that expands a small incision in the conjunctiva/Tenon's capsule facilitated the performance of strabismus surgery through a fornix incision. A wide field of exposure revealed the entire area of the muscle insertion. While there is a risk of conjunctival tearing in elderly patients, the use of the retractor is valuable.
