Standardisation improves accuracy, which can be performed via a computerised staircase methodology. Standard clinical tests with scoring of 0.02 per optotype implies an incremental score per optotype despite optotype size remaining constant on each line. The aim of this study is to establish if near continuous incremental optotype display and scoring improves test-retest variability compared to current testing methods.Methods: A computerised three up, one down adaptive staircase was used to display Kay Picture optotypes on an LCD monitor. Three methods of visual acuity assessment were undertaken: ETDRS, Kay Pictures and computerised Kay Pictures. Tests were performed twice under standard clinical conditions.Results: One hundred nineteen adults were tested. Test-retest variability for computerised Kay pictures was 0.01 logMAR (±0.04, p = 0.001). Good levels of agreement were observed for computerised Kay pictures in terms of test-retest variability, where the test had the smallest mean bias (0.01 logMAR compared to 0.03 and 0.08 logMAR for Kay Pictures and ETDRS respectively) and narrowest limits of agreement. Participants performed better in computerised Kay pictures than Kay Pictures by 0.03 logMAR, and better in ETDRS than computerised Kay pictures by 0.1 logMAR.Conclusion: Computerised Kay pictures exhibited a low test-retest variability, demonstrating it is reliable and repeatable. This repeatability measure is lower than the test-retest variability of the ETDRS and Kay Pictures tests.","PeriodicalId":36083,"journal":{"name":"British and Irish Orthoptic Journal","volume":" ","pages":"93-100"},"PeriodicalIF":0.0,"publicationDate":"2022-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9306677/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40594164","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Patients consult eye care practitioners mainly due to symptoms they experience. To enhance targeted treatments from various anomalies, it is relevant to study symptoms with associating anomalies.Aim: To determine the frequencies of refractive error, accommodative and vergence anomalies, and their associations with symptoms in sample of Black South Africans.Method: This prospective, cross-sectional study comprised consecutive participants aged 10-40 years who attended the author's optometry practice in a Black population in South Africa. Visual acuity, refraction, accommodative and vergence tests were performed. Anomalies were classified as either single measure or syndromes based on the number of failed clinical signs.Results: Participants (n = 254) had mean age 22.6 ± 7.22 years. Ninety-four were male (37%) and 160 were female (63%). The frequencies of syndrome anomalies were accommodative insufficiency 17 [(6.6%) 95% CI 3.9-10.5%)], accommodative infacility 32 [(12.6%)] 8.7-17.3%] and convergence insufficiency 22 [(8.6%, 5.1-12.3%)]. Frequencies of coexisting anomalies were refractive error and accommodative 150 (60.0%), refractive error and vergence anomalies 136 (54.4%) and vergence and accommodative disorders 155 (62.0%). Most patients were symptomatic (70.9%). Headache was the most frequent symptom (41.1%).Conclusion: Accommodative anomalies were more frequent than refractive error and vergence anomalies. The high frequency of anomalies suggests a high uptake of optometric services for asthenopia. Accommodative anomalies were the most symptomatic. The study highlights the need for diagnosing visual symptoms and coexisting anomalies. Establishment of validated study protocols for all accommodative and vergence anomalies is recommended.","PeriodicalId":36083,"journal":{"name":"British and Irish Orthoptic Journal","volume":" ","pages":"76-92"},"PeriodicalIF":0.0,"publicationDate":"2022-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9284986/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40644246","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Data from visual function assessments (inclusive of visual acuity, visual fields, eye movements and visual perception evaluation) were analysed to determine whether presence and/or type of visual impairment impacted on cognitive screening scores achieved. Covariates, including glasses use, gender, age at stroke onset and stroke type, were used to assess confounding impacts on scores attained during cognitive screening.Results: 1500 stroke admissions were recruited. One hundred ninety-seven who completed the OCS, were identified from the IVIS study database. Those who reported visual symptoms performed worse statistically on all cognitive tasks except the recall recognition (p = 0.232) and executive tasks (p = 0.967).

However, it puts high demands on the visual system. Current evidence shows conflicting impacts on visual parameters. Therefore, this study explores the changes to vision following VR gameplay.Methods: The study was conducted at the School of Health Sciences, University of Liverpool. All participants had binocular vision with good visual acuity and no manifest strabismus. Participants were assessed before and after playing 15 minutes of the VR game Beat Saber, which incorporated convergence and divergence movements. Clinical assessments including near point of convergence (NPC) and near point of accommodation (NPA) using the RAF rule; accommodative convergence to accommodation (AC/A) ratio; motor fusion using the prism fusion range (at 33cm), accommodation facility using +2.00/-2.00DS flipper lenses, and stereoacuity using the Frisby stereo test were assessed before and after playing.Results: Seventy-eight participants (19-25 years old) were included in the study, with 16 males and 41 females respectively. The breakpoint of convergence reduced by 0.5 cm (p = 0.001). The binocular accommodative facility improved by 2 cycles per minute (cpm); p = 0.004. The mean, near horizontal prism fusion range (PFR) base break and recovery points both worsened by of 5.0 dioptres (p = 0.003), whereas the mean near horizontal PFR base in recovery point improved by of 4.0 dioptres (p = 0.003).Discussion: The study validated previous findings as VR gameplay over-exercised and fatigued convergence muscles, but to a small degree. The VR experience improved the participants' ability to change focus quickly and improve accommodation, as well as the divergence function of the eye. However, as the participants were retested directly after the VR gameplay, the findings were limited to short term effects on vision.","PeriodicalId":36083,"journal":{"name":"British and Irish Orthoptic Journal","volume":" ","pages":"57-64"},"PeriodicalIF":0.0,"publicationDate":"2022-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9249003/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40520437","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our study aims to characterise the clinical features of patients with DS and nystagmus.Methods: A retrospective medical-records review was conducted of all patients with a diagnosis of DS and nystagmus seen at Moorfields Eye Hospital over a ten-year period.Results: Fifty-one subjects were identified, with complete data in 48. The mean age at presentation was 5.1 years (range 0-26 years). The mean binocular LogMAR visual acuity was 0.55(95%CI 0.53-0.57), mean refractive error was -1.8 Dioptre Sphere, DS (95% CI - 5.251.63) with -1.2 Dioptre Cylinder, DC (95% CI - 1.6-0.7).

Eleven patients had associated cataract. Additional diagnoses unrelated to DS were made in 10.4%.Conclusions: The most frequent type of nystagmus in our cohort was 'presumed' INS. This study highlights the importance of differentiating between FMNS and INS (with a latent component), so that further investigations can be performed as appropriate. Almost 25% had associated cataract, and a further 10% other diagnoses un-associated to DS.

Evidence shows increased staff satisfaction and empowerment and decreased medical errors as a result of preceptorship. There is limited literature that includes allied health professionals, particularly new orthoptic graduates. This study aims to: 1) explore the effectiveness of the British and Irish Orthoptic Society (BIOS) preceptorship programme at providing support and confidence in newly graduated orthoptists, 2) explore new graduates' experience of embedding public health in their clinical practice.Methodology: Focus groups were organised for mentors and mentees to discuss their experiences with the BIOS preceptorship programme and how it facilitated embedding public health into clinical practice. Constant comparison analysis was used to identify key themes of discussion.Findings: The preceptorship document promoted structure, reflection, and engagement all of which contributed to effective transition for the mentees. However, document navigation, lack of preceptorship exposure at undergraduate level and leadership engagement were potential barriers to using the programme. The programme encouraged public health engagement among new graduates but barriers such as time pressure, lack of experience and patient understanding were challenges that often prevented the adoption of public health skills and behaviours within their practice.Conclusion: The BIOS preceptorship successfully supports new graduates in their transition into an autonomous practitioner. The programme could be improved by the implementation of a guidance document to assist mentors in their role. Preceptorship engagement could be improved by increasing exposure to undergraduate orthoptic students and departments alike.","PeriodicalId":36083,"journal":{"name":"British and Irish Orthoptic Journal","volume":"18 1","pages":"1-10"},"PeriodicalIF":0.0,"publicationDate":"2022-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8815440/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39934563","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Head trauma is one of the most common causes of abducens nerve palsy. Orbital and/or facial injuries could also affect the LR muscle directly or the orbital course of abducens nerve and lead to palsy. We present a case of a young man with multiple orbital fractures and an impingement of the LR muscle resulting in a complete loss of abduction.Case report: A 29-year-old male reported falling 15 feet. He presented with diplopia and had complete abduction deficit of the left eye. Orbital CT imaging revealed a bony spur from his left zygomatic bone impinging on the lateral rectus muscle. In view of -4 abduction deficit, he was operated upon to remove the bony spur. This led to a gradual, but complete recovery of his abduction.Discussion: The abducens nerve has a tortuous course and as a result is commonly injured during head trauma, in particular due to its vulnerability as it passes into Dorello's canal, or its journey through the cavernous sinus. The case report highlights orbital causes such as direct muscle avulsion or injury to the orbital portion of the abducens nerve, as reasons for how LR weakness could be easily overlooked, unless specifically examined with high-resolution orbital imaging.Conclusion: Orbital mechanical causes can be overlooked in LR palsy. We emphasise the role of orbital imaging in any patient with abducens nerve or LR Palsy and reaffirm that not all cases are associated with an intracranial cause.","PeriodicalId":36083,"journal":{"name":"British and Irish Orthoptic Journal","volume":"17 1","pages":"150-154"},"PeriodicalIF":0.0,"publicationDate":"2021-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8663747/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39772469","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Depth cameras have been suggested as a reliable measurement device for measuring head position using face-tracking technology. This study compared a depth camera (Microsoft Kinect) to a gold standard electromagnetic tracking system (Polhemus device) to measure head position.Method: Twenty healthy volunteers (mean age 21 years) had their head position simultaneously recorded using the depth camera (Kinect) and the electromagnetic tracking system (Polhemus). Participants were asked to make 30-degree head movements into chin up, chin down, head turn and head tilt positions. The head movement made and the stability of the head at each position were recorded and analysed.Results: Compared to the electromagnetic tracking system (Polhemus), the depth camera (Kinect) always measured a smaller head movement. Measurements with the two devices were not statistically significantly different for turn right (P = 0.3955, p > 0.05), turn left (P = 0.4749, p > 0.05), tilt right (P = 0.7086, p > 0.05) and tilt left (P = 0.4091, p > 0.05) head movements.

Poor vision is an identified risk factor. The aim of this cross-sectional public health surveillance audit was to determine the prevalence of falls experienced in the previous 12 months by adult patients presenting to an ophthalmology department.Methods: A short questionnaire was given to consecutive patients attending an ophthalmology department at two trusts in the North West to determine whether they had experienced a fall in the previous 12 months, whether they had suffered a fracture, their eye condition and the type of glasses worn.Results: Data was collected for 585 patients (mean age: 69 years, SD: 13.8). Falls in the previous 12 months were reported by 96 (16.4%) patients, and a significant proportion of these were aged 60 years and over (82%, p < 0.0001, one-sample binomial test). Half of the respondents were unaware of their eye health condition for which they were attending the department. Glaucoma was the most prevalent condition in those who had experienced a fall (43%). A significant proportion of the individuals who reported a fall wore single-vision glasses (43%, p < 0.0001, one-sample chi-square test).Conclusion: In an ophthalmology outpatient department, the proportion of older adults who experienced a fall in the previous 12 months was lower than the reported prevalence in the general population.
