How Can We Better Inform Patients of the Importance of Contact Lens Compliance?: Current Perspectives.

Compliance with contact lens care is important for successful contact lens wear and for minimizing the risk of complications related to lens wear. There are many components of overall lens care guidelines that may potentially be disregarded, forgotten, or misunderstood. Literature has reported copious data on rates of poor compliance for separate lens care recommendations. Knowing the areas of contact lens care where lens wearers perform poorly is helpful when creating strategies for improving patient education. As science evolves and new best-practices are determined, eye care providers must be engaged in educating new lens wearers and reeducating existing wearers. It is vital to make wearers mindful of proper lens care and why proper lens care should be important to them. Various educational strategies can help practitioners to communicate with their patients more effectively. The purpose of this narrative review is to discuss studies of noncompliance with contact lens wear; consequences of these noncompliant behaviors; and studies of lens care education which were found with a literature search. The resulting discussion also includes strategies to improve compliance with patient contact lens wear.

A Comparative Study of the Hand-held IC200 and Slit Lamp-mounted ST500 rebound tonometers with Goldmann Applanation Tonometry

To compare the agreement and repeatability of intraocular pressure (IOP) measured with the slit lamp-mounted ST500 rebound tonometer (iCare Finland Oy, Helsinki, Finland), the hand-held IC200 rebound tonometer (iCare Finland Oy) and Goldmann applanation tonometry (GAT). Cross-sectional study. Glaucoma patients and staff of the Eye Care Centre, Nova Scotia Health, Halifax, Canada. IOP was measured twice each with the IC200, ST500, and GAT. Bland-Altman analysis was used to compare each pair of tonometers and whether the difference between tonometers depended on mean IOP. Intra-class correlation coefficients were also computed. Repeatability of the measurements with each tonometer was assessed by calculating the mean and variance of the difference between the first and second measurement. The relationship between IOP and central corneal thickness was also evaluated. Agreement and repeatability of IOP measurements with the IC200, ST500 and GAT. One eye of 157 participants (64 men and 93 women) with a median (Interquartile range) age and CCT of 62 (45 - 72) years and 553 (533 - 572) μm, respectively, were enrolled. Median IOP with the IC500, ST500 and GAT was 17.1 (14.3 - 21.0), 16.5 (14.0 - 20.8) and 17.0 (14.0 - 20.5) mm Hg, respectively, while the range of IOP (measured with GAT) was 8.5 to 53.0 mm Hg. Measurements with the three tonometers were not statistically different from each other and in neither of the three paired comparisons was the difference in IOP between two tonometers dependent on mean IOP. The ICC values (0.97-0.98) showed excellent agreement between the tonometers. The variance of the difference between the first and second measurements of the ST500 was significantly lower than that of GAT (P = 0.04) and IC200 (P < 0.01). ICCs for intra-tonometer repeatability were also excellent (0.97-0.99). The ST500 shows good agreement with GAT over a large range of IOP, and significantly higher repeatability compared to the IC200 and GAT, suggesting it may be advantageous in clinical settings where topical anesthesia or skilled staff are unavailable.

Post-Cataract Surgery Fungal Endophthalmitis: 6-Year Experience in Management and Outcomes at a Tertiary Eye Care Center.

This study aimed to describe the functional and anatomical outcomes of post-cataract surgery fungal endophthalmitis at King Khaled Eye Specialist Hospital (KKESH). A retrospective analysis of clinical data from a single institution was performed. This study included 29 patients with post-cataract surgery endophthalmitis with suspected or confirmed fungal etiology who presented between January 1, 2017, and December 31, 2022. We evaluated demographics, clinical features, microbiological assessments, and treatment strategies. The effects of various treatments on outcomes were analyzed. The need for additional treatment and functional and anatomical outcomes was also investigated. The mean time from surgery to the onset of ocular symptoms was 52.1 (SD ± 59.9; range, 3-210) days, and the mean time from surgery to the first visit to KKESH was 81.4 (SD ± 103.5; range, 2-510) days. Low culture positivity was noted in four samples, with two revealing Aspergillus sp. and two revealing Cladosporium sp. Of the 29 patients, 6 underwent pars plana vitrectomy (PPV) and received intravitreal antimicrobial/antibiotic injections. Two of the six patients also underwent simultaneous intraocular lens removal. The average number of additional treatments, regardless of visual acuity, was lower in the PPV group than in the conservative group (0.5 [SD ± 1.1; range, 0-3] and 1.48 [SD ± 1.47; range, 0-6], respectively). In the PPV group, 50% (n=3) of the eyes achieved functional success and 83.3% (n=5) of the eyes achieved anatomical success. In contrast, in the conservative group, 43.5% (n=10) of the eyes achieved functional success and 69.6% (n=16) of the eyes achieved anatomical success. For post-cataract surgery fungal endophthalmitis, a high index of suspicion and prompt PPV with empirical administration of intravitreal antifungal agents are required to achieve a favorable prognosis.

Associations between School-Based Vision Program Outcomes and School Characteristics in 410 Schools.

School-based vision programs (SBVPs) deliver vision care services directly to students at school, helping address disparities in access to pediatric vision care. We aim to evaluate the associations between SBVP outcomes and school-level characteristics. Retrospective cross-sectional data analysis PARTICIPANTS: Public schools with at least 50 SBVP-enrolled students 5 to 22 years old with complete demographic data. Schools with fewer than 60% of total grade levels served by the SBVP were excluded, resulting in a sample of 410 schools. Vision screening and eye exam data were extracted from Helen Keller International's United States Vision Program dataset from 2016 through 2022. Individual student data were aggregated to characterize each school's SBVP outcomes and analyzed with schools' publicly available socioeconomic and demographic data (student body race and ethnicity composition, proportion of students qualifying for free and reduced-price meals [FARM%], and proportion of English Language Learners). Descriptive statistics summarized SBVP outcomes. Fractional regression models were utilized to understand associations between SBVP outcomes and school characteristics. SBVP outcomes were rates of vision screening failure, eyeglasses prescription, and community eye care referral among each school's SBVP-enrolled students. We evaluated 151 (36.8%) elementary, 155 (37.8%) middle, and 104 (25.4%) high schools, with a median FARM% of 87.4% and a plurality of Hispanic students in 61.0% of schools. Overall median rates of vision screening failure, eyeglasses prescription, and referral were 38.4%, 25.2%, and 5.4%, respectively. High schools were associated with increased screening failure and eyeglasses prescription rates and a decrease in referral rate, compared with elementary schools. In multivariate analysis, each 10% increase in FARM% was associated with a 2.6% (95% confidence interval [CI]: 1.54-3.65), 1.8% (CI: 0.87-2.74), and 0.86% (CI: 0.36-1.36) increase in screening failure, eyeglasses prescription, and referral rates, respectively. There is significant vision care demand among public schools, especially those with student populations from lower socioeconomic backgrounds. SBVPs are important in bridging the gap in pediatric vision care access in such populations. Our findings demonstrated opportunities to allocate program staffing and equipment resources according to schools' anticipated needs, thus maximizing SBVPs' impact in delivering pediatric vision care.

Descriptive study of patient outcome and satisfaction with telemedicine and physical consultation during and after the COVID-19 pandemic.

This study was conducted to assess patients' outcome and satisfaction with the eye care received with telemedicine and physical consultation at a tertiary care hospital during and after the coronavirus disease 2019 (COVID-19) pandemic. A descriptive study was carried out on 6052 patients who consulted for eye illness at a tertiary care hospital between April 2020 and December 2022. An outcome scoring system was developed and validated for the assessment of patient outcome after providing treatment on telemedicine consultation and physical consultation. Outcome scores for various symptoms were compared pretreatment and posttreatment. Telehealth Usability Questionnaire (TUQ) was used through an online survey to assess patients' satisfaction with teleophthalmology services during the COVID-19 pandemic. An 18-item Patient Satisfaction Questionnaire (PSQ-18) was used to assess the same with physical consultation. A total of 6052 patients were included in the study. Physical consultation group had 2485 patients (41.06%) and the telemedicine group had 3567 patients (58.93%). Male patients constituted 63.11% and females were 36.89%. There was a significant improvement in outcome scores for pain and redness in both physical and telemedicine consultation groups (P < 0.0001). All subgroups of TUQ had significantly high scores (including usefulness, ease of use and learnability, interface quality, interaction quality, and satisfaction and future use), except one subgroup (reliability). Uneducated patients were significantly more satisfied with telemedicine compared to educated patients (P = 0.044). Majority of patients expressed satisfaction with teleophthalmology services. The recent pandemic paved the way for the future integration of telemedicine in ophthalmology, especially if virtual eye examinations attain a higher level of reliability.

Evaluation of Self-vision Assessment Charts in Schools of Eastern Nepal: A Multi Method Study

Introduction: Globally, over two billion people suffer from vision impairment, almost half preventable. In Nepal, the Eastern Regional Eye Care Program introduced self-vision assessment charts in 137 schools for early eye issue detection. This study assessed the charts' use and perceived impact.Methods: A multi-method study was conducted to evaluate the use of self-vision assessment charts in schools in Eastern Nepal. Ethical approval was obtained from Institutional Review Board (Refrence number: 72-079-040). Quantitative data were collected through a questionnaire survey. Quantitative data were analyzed using descriptive statistics, while qualitative data were analyzed using framework analysis. Both methods were integrated to enhance understanding of participants' experiences.Results: In this study, 400 students participated in questionnaire survey, 180 in self vision assessment, and 16 teachers in in-depth interviews. Among the participants, 198 (49.50%) of students used the chart, 125 (65.78%) expressed satisfaction, 241 (60.25%) found it useful, 276 (69%) as beneficial, and 253 (63.25%) stated improved health. There were 93 (23.25%) students who felt knowledgeable about its use, with 18 (10%) using it correctly. In 162 (90%) of schools there were adequate chart placement, 23 (12.77%) provided clear signage for viewing points. Teachers recognized the chart's benefits and encouraged its use, but students lacked awareness. Regular use was viewed as beneficial for early detection of eye issues, though challenges included a need for more awareness among students and teachers and reliance on home remedies.Conclusions: Most students and teachers acknowledged self-vision assessment charts’ benefits but had low utilization and accuracy rates. Strategic interventions such as regular informational sessions, teacher motivation, and engagement with eye health experts are essential.

Parental Ability to Detect Visual or Ocular Anomalies in Their Children

INTRODUCTION: Children typically depend on their parents to seek eyecare. Visual and ocular disorders can be challenging for parents to identify with the absence of apparent symptoms. This may hinder timely clinical diagnosis for children who need treatment. Parental awareness regarding common paediatric eye and vision anomalies along with eye care seeking behaviour has been reported, but there is a lack of studies that demonstrate parental ability to identify a presenting eye or vision disorder in their own children. AIM: This study aimed to determine parental ability to recognise a significant eye problem in their children. METHODS: The study population consisted of beneficiaries of Jaber Al Ahmad Armed Forces Hospital in Kuwait. Structured history and symptoms were taken from parents and comprehensive eye examinations were conducted for their children. Parental responses were compared to the eye test results to attain the study purpose. RESULTS: A total of 188 parental interviews and 188 eye test results data were collected from 137 parents and their children. Only a few parents (18.1%) were able to detect significant visual or ocular anomalies in their children. One-third of the parents (33%) were under the assumption that the visual or ocular status of their children was within the norm, while the eye test results showed that the children had clinically significant issues. Overall, 41.5% of the entire group of parents were wrong in their assumption about the children&amp;rsquo;s visual or ocular status. CONCLUSION: The findings suggest that a large proportion of parents may not be able to identify a presenting eye disorder in their children. This emphasises the significance of routine eye examinations at an early age.

Bird beak-related ocular injuries in southern India: Factors and visual implications

PurposeTo evaluate the visual outcomes and identify prognostic factors in patients with ocular bird beak injuries treated at a tertiary eye care center in South India. MethodsWe conducted a comprehensive analysis of patients with bird beak injuries, considering factors such as age, gender, mode of injury, and size of laceration. The affected eyes underwent detailed examinations using slit-lamp biomicroscopy, and B-scan ultrasonography was performed to assess the status of the posterior segment. Postoperatively, the best-corrected visual acuity (BCVA) was measured at the last follow-up visit. ResultsOur findings demonstrated significant improvements in visual outcomes, including BCVA and uncorrected visual acuity (UCVA), over a follow-up period ranging from 1 week to 3 years (p < 0.05). No significant changes were observed in endophthalmitis, intraocular pressure (IOP), lens status, or retinal abnormalities during the study duration. ConclusionThis retrospective study highlight the potential for favorable long-term visual improvement in patients with ocular injuries caused by bird beaks and emphasize the importance of timely intervention. Delayed surgical treatment and the requirement for multiple surgeries within the first week were found to negatively impact visual acuity. Hence, it is crucial to raise public awareness, particularly in rural areas, to prevent these potentially devastating injuries and ensure early intervention for optimal visual recovery.

Ultimately, microneedle drug delivery presents a revolutionary method with the potential to significantly enhance ocular disease treatment, marking a new era in eye care.

Vision corrections used by presbyopic orienteers

SIGNIFICANCE Evaluating the visual challenges and refractive correction solutions of presbyopic orienteers identifies features of relevance to optometric management of the visual needs of active presbyopes. PURPOSE Orienteering is a unique sport requiring visual clarity at a range of viewing distances and has a high proportion of presbyopic participants. This study evaluates the vision corrections used by presbyopic orienteers, specifically aiming to characterize the prevalence of different vision correction options used and to explore the strengths and limitations of different vision correction solutions. METHODS Orienteers 40 years or older completed an online questionnaire consisting of multiple-choice questions covering personal demographics, orienteering participation, and visual corrections worn in everyday life and for orienteering. Free-text questions asked for further information about the corrections used and advice received from eye care practitioners were analyzed using content analysis. RESULTS There were 469 respondents (195 women, 274 men; median age category, 55 to 59 years). For the 187 people without distance refractive correction, the most frequent corrections for orienteering were “off the shelf” reading spectacles (n = 95) or use of a compass magnifier (n = 24), and for the 277 people with distance refractive correction, they were progressive addition spectacles (n = 96) and monovision contact lenses (n = 63). The main visual challenges faced by orienteers were seeing map detail, lens obstruction from fogging and rain, and difficulty orienteering in low light in the daytime. An ideal correction needed to provide visual clarity for both map and terrain. No visual correction type consistently addressed all challenges. Orienteers valued personalized discussion with eye care practitioners to address their needs. CONCLUSIONS Optimal visual corrections for presbyopic orienteers are individual, but higher reading additions to clarify map detail, contact lenses to avoid lens obstruction, additional light, and solutions that provide clear vision at all viewing distances while avoiding the reading add blurring the ground at the orienteer's feet should be considered. Personalized care is necessary to optimize visual correction solutions.

Referral Pattern and Comanagement of Patients With Keratoconus in West Africa: A Survey-Based Study of Optometrists in Ghana and Nigeria.

To investigate the referral and management patterns of patients with keratoconus among primary eye care practitioners in Ghana and Nigeria. A questionnaire adapted from previous studies was modified and created using Google Forms. The online survey was distributed to prospective participants using e-mails and other social media platforms. Data were analyzed using the Statistical Product and Service Solutions software (version 25.0; IBM Corp, Armonk, NY; Released 2017). One hundred and sixty-nine optometrists responded to the survey (61.54% from Nigeria and 38.46% from Ghana). Most (88.6%) practiced without corneal topographers. Most respondents (77.7%, n=136) reported not fitting rigid gas-permeable (RGP) contact lenses in a year and 68% were willing to refer for contact lens fitting to another practitioner. The major barriers to RGP fitting were lack of experience (44.4%, n=72), cost to practice (15.4%, n=25), and other reasons (12.4%), whereas 27.8% (n=45) preferred not to answer. Seventy-six percent of respondents (n=133) were willing to fit RGPs if the respondents received the training to do so. About half of the respondents (53.8%) reported progression of cornea signs as the reason for referral to an ophthalmologist. Half of the respondents (n=51.4%) did not have a cornea surgeon in the area the respondents practiced, and 76.3% reported not comanaging patients at all with ophthalmologists. This study highlights the current standard of care of patients with keratoconus in West Africa. The findings from this study suggest that clinical guidelines and further training of eye care practitioners in West Africa are needed to better manage patients with keratoconus.

Audit of antibiotic utilization patterns and practice for common eye infections at the ambulatory clinic of a teaching hospital in Ghana: Findings and implications

Background Antimicrobial resistance (AMR) is a serious public health issue which is exacerbated by increased inappropriate use of antibiotics for common eye infections. This cross sectional survey was to assess the appropriate use of antibiotics for eye infections in an ambulatory clinic in Ghana and possible determinants. Method The medical records of all patients who sought eye care between January 2022 to December 2022 and were prescribed antibiotics were extracted from the hospital’s electronic database. Descriptive, bivariate and multivariate analyses were then conducted. Results A total of 1925 patient medical records were extracted, whose median age was 40 years (IQR 26–69), and were mostly females (58.91%, n = 1134/1925). The eye condition commonly treated with antibiotics was bacteria conjunctivitis (33.51%, n = 645/1925). The most prescribed antibiotic was gentamycin (22.96%, n = 442/1925) followed by ciprofloxacin (16.78%, n = 321/1925). These were mostly topical dosage forms (82.13%, n = 1581/1925). Systemic antibiotics prescribed were mostly from the WHO ‘Access’ class (83.33%, n = 280/338). The appropriate choice of antibiotic prescribed was 42.44% (n = 817/1925) and this was positivity associated with age (p&lt;0.001), number of antibiotics prescribed (p &lt;0.001), the prescription of topical dosage forms (p &lt;0.001), and WHO ‘Access’ antibiotic class (p &lt;0.034). Conclusion The level of appropriateness of antibiotic prescriptions for eye infections was sub-optimal. Antimicrobial stewardship programs, including prescriber education on guidelines and prescription audit to address associated factors, must now be instigated in this hospital to improve future antibiotic use and prevent the rise of AMR.

Of the study respondents, less than half (48.5%) were found to have intermediate-level ability to provide primary eye care services. Serving more patients per month (p 0.001), receiving additional training (p 0.005) and having a first degree (p 0.001) were found to have a statistically significant association with the ability to provide primary eye care services.Conclusion: Most primary eye care service providers had a significant knowledge and skill gap. Capacity-building training aimed at enhancing the ability of primary eye care service providers need the appropriate attention.Contribution: This study presents the ability of mid-level healthcare workers to provide primary eye care services to support the elimination of avoidable blindness, resulting in improved quality of life.

Telemedicine in Eye Care During the COVID-19 Pandemic: A Review of Patient & Physician Perspectives.

There has been an increase in the adoption of telemedicine during the COVID-19 pandemic. This review used systematic search and review criteria to assess the literature on patient and physician perspectives toward telemedicine for vision care during the pandemic. We conducted a comprehensive search on PubMed, Embase, and Scopus using relevant MeSH terms to identify peer-reviewed studies examining telemedicine use in eye care during the pandemic. The search strategy encompassed three key concepts: COVID-19 or pandemic, telehealth or telemedicine, and eye care. Further screening of references and similar articles was conducted to identify additional relevant studies. We identified 24 relevant studies published between 2020 and 2022. Of these, 15 focused on patients' perspectives, while 12 explored physicians' perspectives. Predominantly cross-sectional in design, these studies were mainly conducted during the initial wave of the pandemic (March 2020 to June 2020), primarily in urban locations and hospital settings. Patients were satisfied with telemedicine and considered it equally effective to in-person visits. Patients believed telemedicine was convenient, improved eye care access, and a beneficial triage tool. Physicians acknowledged telemedicine's convenience for follow-up assessment and its ability to expand the capacity for emergency cases. However, both patients and physicians voiced concerns about the absence of ancillary examination and technological challenges. Our review highlights the positive impact of telemedicine in eye care during the pandemic. Nonetheless, most studies were limited in sample size. They did not delve into potential disparities based on race/ethnicity, socioeconomic status, and geographic location, factors that could influence patient attitudes toward telemedicine. Further research is warranted to validate the findings from our selected studies and explore factors that influence the implementation of telemedicine, particularly across various eye care subspecialties.

Scleral buckling in retinal detachment due to retinal dialysis - A vitreoretina fellow's perspective.

To analyze the efficacy of scleral buckling in the hands of vitreo-retina (VR) fellows under training in eyes with retinal detachment associated with retinal dialysis and analyze the patient and retinal characteristics in these eyes. We carried out a retrospective consecutive case review at a tertiary eye care center in North India. Records of all the patients who had undergone scleral buckling (SB) for retinal dialysis-associated rhegmatogenous retinal detachment by VR fellows (with less than 2 years' experience) between January 2017 and January 2020 were reviewed. Fifty-three eyes of 53 patients with a mean age of 20.77 years were analyzed. Of the patients, 73.58% were males. History of eye trauma was present in 71.69% patients. A total of 21 residents operated these 53 eyes. SB was able to achieve retinal attachment in a single surgery in 84.9% (45/53) eyes. Mean preoperative best corrected visual acuity was 1.9 ± 1.05 log of minimum angle of resolution (logMAR), which improved postoperatively to 1.07 ± 0.72 logMAR (P < 0.001). Surgical success rate was 85.71% (24/28) in eyes with no proliferative vitreoretinopathy (PVR), 66.66% (2/3) in eyes with PVR-A, 91.66% (11/12) in eyes with PVR-B, and 80% (8/10) in eyes with PVR-C1. Fifty-two eyes had a single dialysis and one eye had two separate dialysis. Six eyes had giant retinal dialysis (dialysis greater than 3 clock hours) and all were due to trauma. Five patients had retinal dialysis in the fellow eye and were diagnosed with bilateral idiopathic retinal dialysis. Scleral buckling is a safe and effective management for retinal dialysis retinal detachment even in the hands of VR fellows under training.

Viewing distance, font size and symptoms of eyestrain in non-presbyopic and presbyopic smartphone users.

Smartphones are the most frequently used digital devices globally with ~6.80 billion users. Despite the ubiquitous use of smartphones, limited information is known on the preferred viewing distance and font size of smartphone users. This study investigated viewing distance, font sizeand symptoms of eyestrain in non-presbyopic and presbyopic smartphone users. In this quantitative research study, viewing distance and font size were measured in a group of non-presbyopes (n = 107) and presbyopes (n = 53), whilst participants viewed a text message and a web page on their own smartphone. Subjects also responded to a verbal questionnaire related to the characteristics of their smartphone and the computer vision syndrome questionnaire to assess symptoms of eyestrain. Data were analysed using descriptive and inferential statistics. For the total sample, the mean viewing distance for a text message was 37.13 ± 8.82 cm (median 36.00 cm), and for a web page was 36.11 ± 7.98 cm (median 36.00 cm). Presbyopes had longer median viewing distances compared with non-presbyopes for a text message (41 cm vs. 34 cm, p < 0.001) and web page (40 cm vs. 34 cm, p < 0.001). The font size for non-presbyopes were <1.0 M whilst for presbyopes were >1.2 M. More than twice the percentage of non-presbyopes were classified with digital eyestrain (DES) compared with presbyopes. Non-presbyopes used shorter viewing distances, smaller font sizes and were more predisposed to DES than presbyopes. The viewing distances adopted by presbyopes were similar to the conventional near-working distance of 40 cm. Eye care practitioners should consider viewing distances when assessing near-visual functions and prescribing a near refractive correction, particularly in non-presbyopes. There should be greater awareness of the importance of adopting appropriate viewing distances when using smartphones.

Knowledge of Cerebral Visual Impairment (CVI) in Children among Eye Care Professionals in Selangor and Kuala Lumpur, Malaysia

Objective: Cerebral Visual Impairment (CVI), a brain-based visual disorder that affects neural networks that process incoming visual information throughout the brain, poses challenges in diagnosis and managing visual impairment in children. With the prevalence rise in CVI cases among children, there is a growing demand for ophthalmologists and optometrists to address these conditions, emphasising the importance of improving knowledge and awareness for better visual rehabilitation. This study intends to quantify the level of understanding of CVI in children among eye care professionals in Selangor and Kuala Lumpur, Malaysia.Material and Methods: Two hundred thirty registered eye care professionals, including ophthalmologists and optometrists across Selangor and Kuala Lumpur, Malaysia, participated in this cross-sectional web-based survey. A standardised questionnaire was created through Google Forms and distributed via social media platforms between April and June 2022.Results: The finding showed that the eye care professionals have significantly basic knowledge regarding CVI in children (x2=369; df=2; p-value≤0.01). Most respondents correctly identified variable loss of vision, visual field defects, and abnormal behaviour as clinical features of CVI in children. Additionally, over half of the respondents selected magnetic resonance imaging (MRI) as the appropriate investigation choice.Conclusion: These findings indicate that eye care professionals have basic knowledge and awareness of CVI in children. More research is needed to enhance knowledge and raise awareness about CVI in children among eye-care professionals.
