BACKGROUND: Amblyopia is a common neurodevelopmental disorder of vision that is characterised by visual impairment in one eye and compromised binocular visual function. Existing evidence-based treatments for children include patching the nonamblyopic eye to encourage use of the amblyopic eye. Currently there are no widely accepted treatments available for adults with amblyopia. The aim of this trial is to assess the efficacy of a new binocular, videogame-based treatment for amblyopia in older children and adults...

Building on long-term benefits of early intervention (Paper 2 of this Series) and increasing commitment to early childhood development (Paper 1 of this Series), scaled up support for the youngest children is essential to improving health, human capital, and wellbeing across the life course. In this third paper, new analyses show that the burden of poor development is higher than estimated, taking into account additional risk factors. National programmes are needed. Greater political prioritisation is core to scale-up, as are policies that afford families time and financial resources to provide nurturing care for young children...

A 34-year-old man presented with an acute onset of upbeat nystagmus, slurred speech, and limb and truncal ataxias. The patient had a history of limb ataxia and gait disturbance previously treated as brainstem encephalitis with corticosteroids 3 years previously. Brain magnetic resonance imaging showed pontine developmental venous anomaly (DVA) and hemorrhagic infarction within the drainage territory of the DVA. Three months later, the patient exhibited recurrent limb ataxia, double vision, and numbness of the left side of the body...

Optic disc pits are an uncommon congenital abnormality. Patients remain asymptomatic unless they develop maculopathy. We present a rare case of a double optic disc pit of which only three others have been reported worldwide. A 51-year-old gentleman presented with blurred vision. Fundoscopy revealed a right double optic disc pit. Though he was symptomatic there was no evidence of maculopathy. OCT of macula and disc was otherwise unremarkable. Visual field demonstrated a paracentral defect. Although optic disc pits are rare they are still an important clinical entity...

Diagnosing the underlying etiology of diplopia requires a structured approach. Double vision can arise from ocular, mechanical, or neurologic causes. A careful history can greatly improve a targeted examination. The approach to initial diagnosis and examination in cases of diplopia has been previously described. Here the authors expand upon those recommendations, and add new techniques recently described in the literature, which may influence the approach to the diplopia patient. A description of the approach to the examination of torsion is discussed...

BACKGROUND: Postoperative shivering is a major problem in children undergoing general anesthesia. OBJECTIVES: The aim of the present study was to investigate the role of low-dose intravenous ketamine for prevention of shivering after induction of general anesthesia in children who had undergone tonsillectomy. PATIENTS AND METHODS: This was a randomized, double-blinded, placebo-controlled trial including 80 children, of American society of anesthesiologists (ASA) physical status I or II, scheduled for tonsillectomy under general anesthesia who were randomly assigned to an intravenous ketamine (0...

Trips over obstacles are one of the main causes of falling in older adults, with vision playing an important role in successful obstacle negotiation. We determined whether a horizontal-vertical illusion, superimposed onto low-height obstacles to create a perceived increase in obstacle height, increased foot clearances during obstacle negotiation thus reducing the likelihood of tripping. Eleven adults (mean ± 1 SD: age 27.3 ± 5.1 years) negotiated obstacles of varying heights (3, 5, 7 cm) with four different appearance conditions; two were obstacles with a horizontal-vertical illusion (vertical stripes of different thickness) superimposed on the front, one was a plain obstacle and the fourth a plain obstacle with a horizontal black line painted on the top edge...

Motor adaptation due to task practice implies a gradual shift from deliberate control of behavior to automatic processing, which is less resource- and effort-demanding. This is true both for deliberate aiming movements and for more stereotyped movements such as locomotion and equilibrium maintenance. Balance control under persisting critical conditions would require large conscious and motor effort in the absence of gradual modification of the behavior. We defined time-course of kinematic and muscle features of the process of adaptation to repeated, predictable perturbations of balance eliciting both reflex and anticipatory responses...

Trochlear nerve schwannoma is extremely rare, with only 35 pathologically confirmed patients being reported in the literature. Here, the authors report a patient of trochlear nerve schwannoma in the prepontine cistern manifesting as facial pain and double vision and presenting the image characteristics of repeated intratumoral hemorrhage, which has never been reported in the literature. Total tumor along with a portion of the trochlear nerve was removed by using a retrosigmoid approach. Facial pain disappeared after operation, and the diplopia remained...

AIM: To describe the surgical management and long-term outcome of a case of symptomatic residual acquired primary position excyclotropia, without changing the primary position vertical deviation. METHODS: This case report describes ipsilateral half tendon width transpositions of the left superior rectus temporally and inferior rectus nasally, combined with right inferior rectus posterior fixation suture at 11 mm. RESULTS: Three days postoperatively, the transposition procedure produced a 10° cyclotorsional change in primary position, resulting in 5° of incyclotorsion (double Maddox rod)...

Carotid cavernous fistulas (CCFs) are abnormal connections between the carotid arteries and the cavernous sinus. CCFs often present with double vision, reduced visual acuity and conjunctivitis. Deteriorating ocular symptoms due to abnormal fistula drainage can potentially cause permanent blindness, and so urgent interventional treatment is necessary. Transvenous embolization of the fistula is the primary treatment option for the majority of patients with symptomatic CCFs. Orbital approaches are considered to be risky compared to the traditional approach via the inferior petrosal sinus, and is thus used as a secondary option...

Complications associated with various local anesthetic techniques have been recorded in case reports and reviews. This current case reports a transient incident of blurred, double vision (diplopia) following a Gow-Gates mandibular block injection. There is descriptive discussion on possibilities associated with intra-arterial injection, intravenous injection, diffusion through tissue planes, and the autonomic nervous system pathway to lend credence suggesting the etiology of the complication. For practitioners, recognizing when a complication arises from anesthesia delivery and managing the patient in an appropriate manner is essential to an overall agreeable outcome...

IgG4-related disease is a systemic disease characterized by lesions with IgG4 positive plasma cell infiltration in the involved organs and a raised serum IgG4 level. We report a patient of 70-year-old male presented orbital inflammation of IgG4-related disease. The patient developed right eye pain, double vision, and reduced eye sight. MRI image revealed mild right ocular proptosis and swelling of right carvenous sinus, bilateral intraorbital extraocular muscles and right optic nerve. Right optic nerve showed ring-like enhancement...
