AbstractUnlike many other sports, Rugby Union has not permitted players to wear spectacles or eye protection. With an industrial partner, World Rugby developed goggles suitable for use while playing rugby for the purposes of growing participation amongst those that need to wear corrective lenses. This study reports on the profile and experiences of goggle wearers. 387 players received the goggles. Data were obtained from 188 (49%) using an online, 75-item questionnaire. 87% “strongly agreed/agreed” that goggles are beneficial and 75% are happy with goggle performance. Common problems reported by 49.7 and 32.6% of respondents were issues with fogging-up and getting dirty. 15 (8%) players stopped wearing the goggles because of fogging-up, limits to peripheral vision and poor comfort/fit. Injuries were reported in 3% of respondents. In none of these cases did the player stop wearing the goggles. From the positive experience of players in the trial, the goggles were adopted into the Laws of the game on July 1, 2019. As the need to correct vision with spectacles is common, and contact lenses are not worn by 80%+of spectacle wearers, the new Rugby goggles will widen participation for those that need to wear refractive correction, or have an existing/increased risk of uniocular visual impairment.

Functional Changes

Aniridia affects many visual aspects of one’s life. This chapter will highlight many of these effects. Functional changes that occur due to aniridia will be discussed. Once the patient’s vision is assessed and goals are established with a thorough eye examination, numerous avenues can be taken to ensure the support of all the patient’s health care providers. Referrals can be made to appropriate professionals to ensure full understanding and management of the ocular condition. Visual acuity is the measurement used to determine vision levels. Normal vision is 20/20, which means that what a normal person sees at 20 feet, the patient sees at 20 feet. If their vision is 20/40, they would need to be at a distance of 20 feet to see what someone with normal vision can see at 40 feet. The decrease in visual acuity in those with aniridia usually ranges from under 20/60 to as low as approximately 20/400. This is due to the lack of development of the macular area, or fovea. The fovea is responsible for our clearest, most precise vision. Those with visual acuity of 20/200 or worse that is best corrected while wearing spectacles or contact lenses in the better-seeing eye are considered legally blind. While most people who suffer from aniridia are not legally blind, they are visual impaired. Visual impairment is defined as visual acuity of 20/70 in the better-seeing eye when optimally corrected with glasses or contact lenses. The designation of “visual impairment” also has a functionality factor. If a person has a reduction in the ability of the eye or the visual system to perform to a normal ability, he/she is considered visually impaired. Visual field is the measurement of peripheral vision. Those with aniridia may have decreased peripheral vision. This is not directly due to aniridia, but rather to glaucoma, which may develop due to structural changes in the eye. Glaucoma is explained in detail in the glaucoma chapter of this book.

Purpose: This report describes a case of bilateral primary angle closure (PAC) progressing to unilateral end-stage primary angle closure glaucoma (PACG) associated with treatment for coronavirus disease-19 (COVID-19) infection. Methods: A 64-year-old man came to our attention because of blurred vision after a 2-month hospital stay for treatment of COVID-19 infection. Examination findings revealed PACG, with severe visual impairment in the right eye and PAC in the left eye due to plateau iris syndrome. The patient’s severe clinical condition and prolonged systemic therapy masked the symptoms and delayed the diagnosis. Medical chart review disclosed the multifactorial causes of the visual impairment. Ultrasound biomicroscopy (UBM) aided in diagnosis and subsequent therapy. Results: The cause behind the primary angle closure and the iridotrabecular contact was eliminated by bilateral cataract extraction, goniosynechialysis, and myotic therapy. Conclusions: COVID-19 treatment may pose an increased risk for PAC. Accurate recording of patient and family ophthalmic history is essential to prevent its onset. Recognition of early signs of PAC is key to averting its progression to PACG.

Prompt Attention

Chapter 15 addresses conditions that require prompt evaluation but are not generally in the group of conditions that are true emergencies. Included in this chapter are acute migraine, other severe nonemergent headaches, facial pain, severe low back pain, acute severe neuropathies such as shingles and diabetic amyotrophy, abdominal pain, and acutely painful muscle conditions requiring prompt attention, such as myositis and rhabdomyolysis. The differential diagnosis of headache with visual impairment is reviewed, as is the differential diagnosis of facial pain. Strategies for the evaluation, diagnosis, and treatment of atypical focal pains that can represent unusual presentations of common problems as well as uncommon conditions are discussed.

Purpose: To investigate the effects of rigid-gas-permeable contact lens (RGP-CL) wear on Zernike astigmatism and visual performance in myopic eyes. Methods: A wavefront sensor was used to evaluate Zernike astigmatism for 21 eyes with minimum astigmatism and 18 eyes with moderate astigmatism under three different modes of refractive correction: the RGP-CL, spectacle lens correcting spherical equivalent (SL) and spectacle lens fully correcting spherical error and astigmatism (fSL). Contrast visual acuity was assessed with a VA tester at four contrast levels and two luminance backgrounds. Results: Compared to the SL wear, RGP-CL wear changed the main axis astigmatism [Formula: see text] from -0.09 ± 0.34 to 0.34 ± 0.22 for the minimum astigmatism group, while the contrast VA was improved about 0.05 LogMAR (F = 8.06, p < 0.01). For the group with moderate astigmatism, significant reduction in [Formula: see text] was found for both fSL wear (t = 4.78, p < 0.001) and RGP-CL wear (t = 6.29, p < 0.0001). The changes in astigmatism were significantly correlated between the fSL and RGP-CL wears (r = 0.897, p < 0.0001 for [Formula: see text]; and r = 0.643, p = 0.004 for [Formula: see text]. Contrast VA was significantly improved for both fSL and RGP-CL wears and the improvements were significantly correlated between each other for all four contrast levels and two backgrounds. Conclusion: RGP-CL wear induces astigmatism for the eyes with minor astigmatism probably due to a correction of corneal astigmatism and thus a manifesting of the lens astigmatism. For the astigmatic eyes, RGP-CL wear has similar effect on correcting astigmatism as the spectacle lens wear with spherical-cylinder correction and also produces similar visual improvement.

Structured Questionnaire

Aims To determine whether club policies exist for junior players concerning the wearing of mouth protectors during training and playing, and whether dental emergency cover is present on both training and match days at Scottish Rugby Union (SRU) affiliated junior clubs. Method A self-reporting structured questionnaire, sent to all SRU affiliated clubs with junior playing members. Results Response rate was 77% (117 out of 151 clubs) showing a wide variation in policies and implementation. Exclusion was reported from training in 11% (13 out of 151) and from playing on match days in 17% (20 out of 151) of clubs if a mouth protector was not worn. The majority of clubs advocated that shop-bought protectors were satisfactory. First aiders were present at training at 86% (130 out of 151) and on match days at 95% (143 out of 151) of clubs. Fewer than 1% had a dentist and only 3% a doctor present at training. On match days fewer than 2% had a dentist and fewer than 20% a doctor present. Conclusion There is a wide variation in club policies and guidelines thus allowing parents, players and club staff considerable latitude in interpretation. A significant number of youngsters will be at increased risk of dental injury. First aiders are present in a significant number of clubs during training and playing.

Purpose:To explore the association between in-season training-load (TL) measures and injury risk in professional rugby union players.Methods:This was a 1-season prospective cohort study of 173 professional rugby union players from 4 English Premiership teams. TL (duration × session-RPE) and time-loss injuries were recorded for all players for all pitch- and gym-based sessions. Generalized estimating equations were used to model the association between in-season TL measures and injury in the subsequent week.Results:Injury risk increased linearly with 1-wk loads and week-to-week changes in loads, with a 2-SD increase in these variables (1245 AU and 1069 AU, respectively) associated with odds ratios of 1.68 (95% CI 1.05–2.68) and 1.58 (95% CI 0.98–2.54). When compared with the reference group (<3684 AU), a significant nonlinear effect was evident for 4-wk cumulative loads, with a likely beneficial reduction in injury risk associated with intermediate loads of 5932–8651 AU (OR 0.55, 95% CI 0.22–1.38) (this range equates to around 4 wk of average in-season TL) and a likely harmful effect evident for higher loads of >8651 AU (OR 1.39, 95% CI 0.98–1.98).Conclusions:Players had an increased risk of injury if they had high 1-wk cumulative loads (1245 AU) or large week-to-week changes in TL (1069 AU). In addition, a U-shaped relationship was observed for 4-wk cumulative loads, with an apparent increase in risk associated with higher loads (>8651 AU). These measures should therefore be monitored to inform injury-risk-reduction strategies.

Safety Incident

Abstract Background The number of individuals with a visual impairment in the UK was estimated a few years ago to be around 1.8 million. People can be visually impaired from birth, childhood, early adulthood or later in life. Those with visual impairment are subject to health inequities and increased risk for patient safety incidents in comparison to the general population. They are also known to be at an increased risk of experiencing medication errors compared to those without visual impairment. In view of this, this review aims to understand the issues of medication safety for VI people. Methods/design Four electronic bibliographic databases will be searched: MEDLINE, Embase, PsycInfo and CINAHL. Our search strategy will include search combinations of two key blocks of terms. Studies will not be excluded based on design. Included studies will be empirical studies. They will include studies that relate to both medication safety and visual impairment. Two reviewers (SG and LR) will screen all the titles and abstracts. SG, LR, RM, SCS and PL will perform study selection and data extraction using standard forms. Disagreements will be resolved through discussion or third party adjudication. Data to be collected will include study characteristics (year, objective, research method, setting, country), participant characteristics (number, age, gender, diagnoses), medication safety incident type and characteristics. Discussion The review will summarise the literature relating to medication safety and visual impairment.

Abstract Visual impairment has emerged as a potential modifiable risk factor for dementia. However, there are a lack of large studies with objective measures of vison and with more than ten years of follow-up. We investigated whether visual impairment is associated with an increased risk of incident dementia in UK Biobank and EPIC-Norfolk. In both cohorts, visual acuity was measured using a “logarithm of the minimum angle of resolution” (LogMAR) chart and categorised as no (≤0.30 LogMAR), mild (&gt;0.3 - ≤0.50 LogMAR), and moderate to severe (&gt;0.50 LogMAR) impairment. Dementia was ascertained through linkage to electronic medical records. After restricting to those aged ≥60 years, without prevalent dementia and with eye measures available, the analytic samples consisted of 62,206 UK Biobank and 7,337 EPIC-Norfolk participants, respectively. In UK Biobank and EPIC-Norfolk. respectively, 1,113 and 517 participants developed dementia over 11 and 15 years of follow-up. Using multivariable cox proportional-hazards models, the hazard ratios for mild and moderate to severe visual impairment were 1.26 (95% Confidence Interval [CI] 0.92-1.72) and 2.16 (95% CI 1.37-3.40), in UK Biobank, and 1.05 (95% CI 0.72-1.53) and 1.93 (95% CI 1.05-3.56) in EPIC-Norfolk, compared to no visual impairment. When excluding participants censored within 5 years of follow-up or with prevalent poor or fair self-reported health, the direction of the associations remained similar for moderate impairment but were not statistically significant. Our findings suggest visual impairment might be a promising target for dementia prevention, however the possibility of reverse causation cannot be excluded.
