The prospect of a nationally funded eye care pathway for adults with LD in England is now a real possibility. This service model has identified a clearly defined unmet need and illustrates the unique skill set orthoptists can offer to address this health inequality. Requiring minimal financial outlay and flexible enough to be integrated into any future national eye care framework, this service has ensured that access to eye care is truly equitable for all people with LD.

To evaluate the success of combining ipsilateral inferior and superior oblique muscle surgery in young children with congenital unilateral superior oblique under action who present in infancy with a large socially noticeable head-tilt.

A consecutive retrospective case series of young children was analysed. The success of surgery in eliminating the head-tilt was evaluated by pre- and post-operative ocular motility assessment focusing on the vertical misalignment in primary position and downgaze, the magnitude of the head-tilt in degrees and the status of the superior oblique tendon.

Five children had a mean age at first surgery of 41 (range 25-63) months, a mean primary position vertical deviation of 26 (25-30) prism dioptres, a head-tilt of 30 (20-35) degrees and a mean post-operative follow up of 24 (8-43) months. While there was a uniform surgical plan, nonetheless each operation required individualisation based on a spectrum of per-operative superior oblique tendon findings. The head tilt was eliminases were not identifiable clinically pre-operatively.

Children and young people with Special Educational Needs (SEN) are 28 times more likely to have eye problems than their typically developing peers. An ideal approach to the eye care for children attending special schools in England has been developed. Work in this area continues to evolve; therefore, an audit about existing services across the United Kingdom (UK) was undertaken.

A survey to ascertain key aspects of services for children with SEN that exist in the UK was developed and disseminated via Survey Monkey and at British and Irish Orthoptic Society (BIOS) events to all leads of the orthoptic profession.

Ninety-four service areas replied to the survey. Of these, 65 areas provide a special school service, 30 also provide a specialist service for SEN's in hospital/community clinics; five provide only a specialist service in hospital/community clinics, and 24 reported no specialist service provision, outside that provided to everyone. In the school environment, 29 (44%) areas include vision and orthoptic assessment, whereas 31 (48%) include vision, orthoptic, and refraction assessment. All but two services were reported as orthoptic-led, 26 (40%) special school services involved optometric input within school, and no services had optical dispensing within school.

The results of this survey suggest that access to all aspects of eye care is not always available in school where a service exists. Families have to travel to the hospital or community optometrist for further assessment, which is not suitable in a number of cases, though it may be desirable, in some.

It is considered normal to have a small amount of superior rectus weakness in laevo and dextro elevation; however, there is no documented definition for these normal parameters within a healthy young adult population using ocular movement testing and the synoptophore. The aim of this study was to collect normative data on the degree of superior rectus underaction in healthy young adults.

Twenty-nine healthy adults (3 males and 26 females, mean age 20.30 ± 1.70 years) were recruited. Superior recti underactions and inferior oblique overactions were recorded during routine ocular movement testing and mean and median values calculated. Subjective horizontal, vertical and torsional measurements were taken in degrees on the synoptophore in primary position, laevo elevation and dextro elevation.

Most participants (79.31%) had some degree of observable superior rectus underaction in either eye or in both eyes on ocular movement testing (mean superior rectus underaction of -0.69 units in laevo elevation and -0.e synoptophore, -0.48 degrees of underaction are the mean levels of weakness to be expected. Superior rectus underactions greater than -1 units for ocular movement testing and -1 degrees on the synoptophore in healthy young adults should be carefully evaluated, together with other important clinical signs.

The Covid-19 pandemic necessitated social distancing restrictions, which placed limitations on access to ophthalmic care to only those who had an imminent risk of sight loss. All other face-to-face consultations were converted to telephone consultations or were postponed. We investigated whether parents were able to test their child's vision using available home vision testing applications, with an aim to aid decision making during a telephone consultation.

Families with follow-up consultations at Birmingham Children's Hospital were asked to test their child's vision at home. Instructions for the use of Peek acuity, or iSight Pro, were emailed to a parent. Parents chose to use a particular app based on available devices at home. Parents were asked to test uniocular visual acuity twice. Home versus hospital acuity was correlated. Home acuity test-retest reliability was acquired. Parental feedback was obtained through questionnaires.

One hundred and three families were contacted, 15 families completed homExtending the impact of parental vision testing will require education by clinicians and further study to increase sample sizes and to improve confidence.

To report the case of acute isolated abducens nerve palsy and anosmia in a healthy 69-year-old female following SARS-CoV-2 infection.

This is a case report of a previously healthy 69-year-old Caucasian female who presented to the emergency eye centre with a four-day history of binocular, horizontal diplopia eight days after testing positive for SARS-CoV-2 infection. Anosmia was her isolated symptom of COVID-19.

The patient was diagnosed with left abducens nerve palsy. Aetiology was presumed to be post-viral as the patient was not diabetic and had no pre-existing microvascular risk factors. Diplopia resolved within 3.5 weeks. Measurements confirmed complete spontaneous recovery of the abducens palsy within 6 weeks.

Cranial nerve palsies may constitute part of the neurological spectrum of COVID-19 disease. This case report aims to raise awareness amongst clinicians of coronavirus-induced neurological symptoms. Research suggests SARS-CoV-2 infection can trigger an aberrant immune response in some individct or indirect virally mediated injuries along the routes of the cranial nerves can cause neuropathy and olfactory dysfunction. The longer latency effects of COVID-19 infection are not well understood. The long-term rehabilitation of patients exposed to COVID-19 is a major public health concern requiring multidisciplinary expertise. This case report highlights the value of the Orthoptist in the diagnosis and care of patients experiencing neuropathy following COVID-19 exposure.

To analyze the changes in the binocular vision parameters after bilateral Epilasik laser vision correction surgery (LVCS).

Medical Research Foundation, Tamil Nadu, India.

Prospective cohort study.

Subjects with a best corrected visual acuity of ≤ 0.0 Log MAR scale and refractive error < 6.00DS of myopia, < 0.75D of astigmatism, and < 1D of anisometropia were included in the study. All subjects underwent a comprehensive eye examination, LVCS workup which included corneal topography, tomography, aberrometry, and dry eye assessment prior to binocular vision assessment. Complete Binocular vision assessment which included stereopsis, fusion for distance and near, near point of convergence, phoria measurement, vergence amplitudes and facility, accommodative amplitudes, response, and facility was performed with the best corrected vision prior to LVCS, one month and six months after the surgery.

Twenty-five subjects of age 23.8 ± 2.9 years were included. Age ranged from 20 to 32 years. Ten were femer LVCS.

Clinically, aniseikonia (a perceived difference in shape and image size between the eyes) is often neglected in anisometropic amblyopia due to assumed measurement difficulties. Therefore, we currently lack evidence on whether correction of aniseikonia is beneficial. This study aimed to determine whether subjective aniseikonia is measurable in anisometropia with or without amblyopia.

Participants (15-52 years) with Anisometropic Amblyopia (n = 7), Anisometropia without amblyopia (n = 6) and Isometropic Controls (n = 6) were recruited. Subjective aniseikonia was measured using three clinical techniques Robertson Technique (RT) (penlight and Maddox rod), Aniseikonia Inspector Version 3 (AI3), and the New Aniseikonia Test booklet (NAT), and a psychophysical adaptive method, the Contrast-balanced Aniseikonia Test (CAT), where dichoptic contrast adjustments compensate for any suppression.

Eighteen participants completed all tests, one Anisometropic Amblyopia participant could only complete the CAT and NAT due.Teaching point Awareness of the radiological manifestations helps recognition of ketamine abuse.The ability to learn abstract generalized structures of tasks is crucial for humans to adapt to changing environments and novel tasks. In a series of five experiments, we investigated this ability using a Rapid Instructed Task Learning paradigm (RITL) comprising short miniblocks, each involving two novel stimulus-response rules. Each miniblock included (a) instructions for the novel stimulus-response rules, (b) a NEXT phase involving a constant (familiar) intervening task (0-5 trials), (c) execution of the newly instructed rules (2 trials). The results show that including a NEXT phase (and hence, a prospective memory demand) led to relatively more robust abstract learning as indicated by increasingly faster responses with experiment progress. Multilevel modeling suggests that the prospective memory demand was just another aspect of the abstract task structure which has been learned.In light of the COVID-19 pandemic, we scrutinize what has been established in the literature on whether entrepreneurship can cause and resolve extreme events, the immediate and long-run impacts of extreme events on entrepreneurship, and whether extreme events can positively impact (some) entrepreneurship and innovation. Based on this, we utilize a partial equilibrium model to provide several conjectures on the impact of COVID-19 on entrepreneurship, and to derive policy recommendations for recovery. KG-501 We illustrate that while entrepreneurship recovery will benefit from measures such as direct subsidies for start-ups, firms' revenue losses, and loan liabilities, it will also benefit from aggregate demand-side support and income redistribution measures, as well as from measures that facilitate the innovation-response to the Keynesian supply-shock caused by the pandemic, such as access to online retail and well-functioning global transportation and logistics.
