[Structure of pediatric ophthalmic pathology in Uzbekistan]. / Struktura detskoi oftal'mopatologii v Uzbekistane.

PURPOSE: This study analyzes the structure of eye diseases in children of different age groups based on the materials of the ophthalmology department of the Tashkent Pediatric Medical Institute (TPMI) clinic for 2018-2021. MATERIAL AND METHODS: A retrospective analysis of statistical coupons was conducted, which included the medical records of 5613 patients of the ophthalmology department of the TPMI clinic. RESULTS: In the age structure of ophthalmopathology in children who received inpatient treatment at the TPMI clinic in 2018-2021, children aged 5 to 14 years (49.5%) and 1 to 5 years (30.7%) were significantly predominant. The proportion of patients under 1 year old was 11.2% and from 14 to 18 years old - 7.5%. Congenital glaucoma (41%) and lens diseases (30.4%) are characteristic of infants (from 0 to 1 year old); in patients aged 1 to 5 years, lens pathology (37%), congenital glaucoma (25.2%), and injuries (24.7%) were more common; in children aged 5 to 14 years, the pathology of the oculomotor apparatus (32%) and injuries (27.7%) prevailed; in the age group from 14 to 18 years, lens diseases (28.4%) and injuries of the organ of vision (28.1%) were detected more often. CONCLUSIONS: The revealed age aspects of nosologies are due to the timing of clinical manifestations of the pathology, late seeking ophthalmic care of parents, presence of a concomitant pathology in the child, which prevents surgical treatment. The results of the study will help optimize planned and emergency ophthalmological care for children in the regions of the republic.

The association of symptomatic vitreous floaters with depression and anxiety.

PURPOSE: To evaluate the levels of anxiety and depression in patients with symptomatic vitreous floaters and to determine the possible correlations of psychological implications with the symptoms duration and possible improvement, the degree of posterior vitreous detachment, and the discomfort severity. METHODS: Ninety patients complaining for floaters and fifty-seven age- and gender-matched healthy-control subjects were recruited. Every participant underwent a complete ophthalmological examination, including funduscopy and optical coherence tomography scans, while clinical and demographic data were also gathered. The Patient Health Questionnaire-9 (PHQ-9), the Zung Depression Inventory-Self-Rating Depression Scale (Zung SDS), and the Hospital Anxiety and Depression Scale (HADS) were completed by everyone. RESULTS: Between the studied groups, no significant differences were detected regarding the clinical and demographic data (p > 0.05). The patients with floaters had significantly higher scores of PHQ-9, Zung SDS, HADS Anxiety, and HADS Depression (p < 0.001). After adjustment for several confounders, PHQ-9 (p = 0.041), Zung SDS (p = 0.003), and HADS Anxiety (p = 0.036) values remained significantly impaired. Among the patients, PHQ-9 and Zung SDS scores were significantly elevated in the patients with floaters duration less than 4 weeks (p < 0.05). Finally, anxiety and depression were significantly correlated with the symptoms duration and intensity, with the floater-associated discomfort, and with the stage of posterior vitreous detachment. CONCLUSION: Vitreous floaters have a negative impact on patients' psychological status, by the terms of enhanced depressive and anxiety levels. To the best of our knowledge, our study is the first in the literature to elaborate the aforementioned association, by assessing three different questionnaires simultaneously.

Painful Eyes in Neurology Clinic: A Guide for Neurologists.

Eye pain is a common complaint among patients presenting to the neurology clinic. It can be related to neurologic diseases, but it can also be a localized eye condition. Such disorders can be misleading, as their benign appearance might mask more grave underlying conditions, potentially leading to misdiagnoses or delayed treatment. Clinicians should be aware of the specific neurologic or systemic disorders (eg, demyelinating diseases or vascular abnormalities) that might first manifest as eye pain. Formal ophthalmic consultation is recommended for patients presenting with eye pain as the predominant complaint especially when red flags for more serious pathology are present.

Current status of contact lenses usage in Korea: A population-based cohort study 2021.

PURPOSE: To investigate trends in contact lens usage in a nationally representative sample of the Korean population in 2021. METHODS: For this retrospective study, we analyzed data of 3,601 Korean participants aged 10-59 years, from the Korea National Health and Nutrition Examination Survey (KNHANES 2021 version), who underwent eye examination, of whom 1,136 individuals (274 men and 862 women) were contact lens users. The demographic trend among Korean contact lens wearers was examined using statistical analyses to investigate the changes in their contact lens-wearing experience, duration of lens use, type of lens used, location of purchase, presence of an Eye Care Practitioner(ECP)'s prescription, lens-related ophthalmic complications, and type of lenses worn at the time of complications, according to sex. Multivariable logistic regression analysis was conducted to examine the association of each variable with the rate of complications and use of soft lenses. RESULTS: The average age of the contact lens users was 33.42±0.33 years, with 70.36% (weighted percentage) of users being women who used contact lenses for significantly longer periods than men (p<0.001). Additionally, only wearing of cosmetic lenses was significantly correlated with the occurrence of complications (p = 0.006), and 6.76% of users purchased lenses without a prescription. Multivariate analysis among the contact lens users revealed a significant relationship between the complication rate and female sex (p = 0.002), pre-existing eye disease diagnosed by ECPs (p = 0.0288), and duration of contact lens use (p<0.0001). CONCLUSION: We identified sex differences in contact lens usage trends in Korea. The main changes observed were an increase in middle-aged lens users and a decrease in female users compared to that in the early 2000s. In addition, contact lens complications were significantly associated with sex and pre-existing eye disease. Therefore, those wearing contact lenses for extended periods should exercise caution and consult eye care specialists in the presence of any symptoms.

Ocular Manifestations of Multiple Sclerosis: A Population-Based Study.

BACKGROUND: To evaluate the population-based frequency and severity of multiple sclerosis (MS)-related ocular diseases. METHODS: Retrospective, population-based study examining patients with MS between January 1, 1998 and December 31, 2011. Patients were identified using the Rochester Epidemiology Project, which is a record-linkage system of medical records for all patient-physician encounters among Olmsted County, Minnesota residents. Diagnosis of MS was confirmed based on neuroimaging, cerebrospinal fluid studies, and serum studies for each patient according to the 2017 McDonald criteria. Patient data were obtained using the medical records and followed through April 1, 2018. RESULTS: Of the 116 patients with MS, 66% were female and the median age of onset was 36 years (interquartile range 27.5-43.5 years). About half (61/116, 53%) had MS-related neuro-ophthalmic manifestations during their disease course, and about one-fourth (33/116, 28%) had visual symptoms as their presenting symptom of MS, most commonly as optic neuritis (26/116, 22%). Optic neuritis was the leading MS-related ocular condition (37%), followed by internuclear ophthalmoplegia (16%) and nystagmus (13%). Optic neuritis was mostly unilateral (40/43, 93%), with 16% (6/43) having a visual acuity of 20/200 or worse at nadir but ultimately 95% (35/37) improving to a visual acuity of 20/40 or better. CONCLUSIONS: This study provides the population-based frequency of MS-related ocular disease, which demonstrates a high frequency of ocular manifestations in MS both at disease onset and during the disease course, emphasizing the utility of neuro-ophthalmologists, or collaboration between neurologists and ophthalmologists, in the care of patients with MS.

Congenital ectropion in Noonan syndrome.

Ten-year-old female patient, with facial dysmorphia, scoliosis, short stature, muscular hypotonia, patent foramen ovale and maturational delay, presented for correction of bilateral congenital ectropion. Ophthalmological examination revealed bilateral lower eyelid ectropion, euryblepharon and lagophthalmos, with a positive Bell's phenomenon. She was treated with full-thickness autologous skin grafts on the lower eyelids with bilateral lateral canthoplasty, resolving the ectropion and improving eyelid occlusion. Subsequently, a genetic study was performed that revealed a mutation in the PTPN11 gene and allowed, together with the clinical picture, to make the diagnosis of Noonan syndrome. Noonan syndrome is a multisystem genetic disorder with a wide variety of phenotypes, which usually presents with ocular and periocular disorders. Eyelid ectropion, a distinctive feature of this patient, is a rare ophthalmological manifestation of this syndrome that can be corrected with full-thickness skin graft and lateral canthoplasty.

Diagnostic Challenges of Ocular Rosacea.

OBJECTIVE: This study aims to address the issues surrounding the diagnosis of ocular rosacea and to evaluate the development of the patients' condition after treatment, as well as to distinguish between healthy and diseased patients using a glycomic analysis of tears. METHODOLOGY: A prospective study was conducted to assess a total of 68 eyes in 34 patients over a six-week period. These patients were diagnosed with ocular rosacea based on subjective symptoms and clinical examination. The study monitored the development of objective and subjective values. The difference between patients with the pathology and healthy controls was established by means of analysis of glycans in tears. RESULTS: Skin lesions were diagnosed in 94% of patients with ocular rosacea, with the most commonly observed phenotype being erythematotelangiectatic (68.8%). The mean duration of symptoms was 29.3 months (range 0.5­126 months) with a median of 12 months. Throughout the study, an improvement in all monitored parameters was observed, including Meibomian gland dysfunction, bulbar conjunctival hyperemia, telangiectasia of the eyelid margin, anterior blepharitis, uneven and reddened eyelid margins, and corneal neovascularization. The study also observed improvements in subjective manifestations of the disease, such as foreign body sensation, burning, dryness, lachrymation, itching eyes, photophobia, and morning discomfort. The analysis of glycans in tears partially separated tear samples based on their origin, which allowed for the differentiation of patients with rosacea from healthy controls. In the first sample, the pathology was determined in a total of 63 eyes (98.4%) of 32 patients, with further samples showing a change in the glycomic profile of patients' tears during treatment. CONCLUSION: The study demonstrated objective and subjective improvements in all the patients. Tear sampling and analysis could provide a means of timely diagnosis of ocular rosacea.

Beyond Vision: A View from Eye to Alzheimer's Disease and Dementia.

With the aging of the global population, the health care burden of Alzheimer's disease (AD) and dementia is considered to increase dramatically in the coming decades. Given the insufficiency of effective interventions for AD and dementia, clinical research on identifying potentially modifiable risk factors and early diagnostic biomarkers becomes a public health priority. Currently, extracerebral manifestations with a large proportion of ocular involvement are usually recognized to precede the symptoms of AD and dementia. Growing epidemiologic evidence also suggests that eye disorders, such as cataracts, age-related macular degeneration, glaucoma, diabetic retinopathy, and so on, are closely associated with and even have a higher incidence of AD and dementia. The eye, as an extension of the central nervous system, therefore has the potential to provide a feasible approach to detecting structural and functional abnormalities of the brain. Numerous new imaging modalities are developed and give novel insights into the detection of several neurodegenerative, vascular, neuropathological, and other ocular abnormalities of AD and dementia in scientific research and clinical application. This review provides an overview of the epidemiologic associations between eye disorders and AD or dementia and summarizes the recent advances in ocular examinations and techniques employed for the detection of AD and dementia. With more brain-and-eye interconnections being identified, the eye is becoming a noninvasive and easily accessible window for the early diagnosis and prevention of AD and dementia.

Ocular therapeutics and the profession of optometry in South Africa.

BACKGROUND:  The role of an optometrist as defined by the World Council of Optometry includes the management of ocular diseases. In 2015, the scope of optometry in South Africa was expanded to include ocular therapeutic drugs. To date approximately 27 optometrists have obtained full certification to exercise ocular therapeutic privileges. AIM:  This study aimed to determine the interest, readiness, as well as challenges, of optometrists for the inclusion of ocular therapeutics into daily practice. SETTING:  The study was set in South Africa. METHODS:  A descriptive, cross-sectional study design was employed. Convenience sampling was used to recruit 420 participants from a study population of optometrists registered with the Health Professions Council of South Africa, with data collected using an online questionnaire hosted on social media platforms and distributed by professional organisations. Data were analysed using the Statistical Package for Social Science version 27. RESULTS:  The majority of respondents (73.3%) reported keenness for ocular therapeutics certification. While 75.7% of respondents had obtained diagnostics certification, only 9.5% were registered with the Health Professions Council of South Africa (HPCSA) with ocular therapeutics certification. Most (92.1%) respondents reported the required minimum of 600 h of clinical training as a major challenge to obtaining ocular therapeutics certification. Almost all (96.9%) of the respondents agreed that ocular therapeutics certification will improve provision of optimal eyecare. CONCLUSION:  South African optometrists support and are personally interested in ocular therapeutics certification. However, while there is a preponderance of diagnostically qualified optometrists, very few are certified for ocular therapeutics with completion of the required clinical training for certification perceived as the greatest challenge.Contribution: This findings in this study highlight that, current requirements to support ocular therapeutics certification of South African optometrists should be reviewed to ensure an enabling environment for the completion of the clinical training.

Clinical utility of handheld fundus and smartphone-based camera for monitoring diabetic retinal diseases: a review study.

Diabetic retinopathy (DR) is the leading global cause of vision loss, accounting for 4.8% of global blindness cases as estimated by the World Health Organization (WHO). Fundus photography is crucial in ophthalmology as a diagnostic tool for capturing retinal images. However, resource and infrastructure constraints limit access to traditional tabletop fundus cameras in developing countries. Additionally, these conventional cameras are expensive, bulky, and not easily transportable. In contrast, the newer generation of handheld and smartphone-based fundus cameras offers portability, user-friendliness, and affordability. Despite their potential, there is a lack of comprehensive review studies examining the clinical utilities of these handheld (e.g. Zeiss Visuscout 100, Volk Pictor Plus, Volk Pictor Prestige, Remidio NMFOP, FC161) and smartphone-based (e.g. D-EYE, iExaminer, Peek Retina, Volk iNview, Volk Vistaview, oDocs visoScope, oDocs Nun, oDocs Nun IR) fundus cameras. This review study aims to evaluate the feasibility and practicality of these available handheld and smartphone-based cameras in medical settings, emphasizing their advantages over traditional tabletop fundus cameras. By highlighting various clinical settings and use scenarios, this review aims to fill this gap by evaluating the efficiency, feasibility, cost-effectiveness, and remote capabilities of handheld and smartphone fundus cameras, ultimately enhancing the accessibility of ophthalmic services.

Reliability and accuracy of artificial intelligence ChatGPT in providing information on ophthalmic diseases and management to patients.

PURPOSE: To assess the accuracy of ophthalmic information provided by an artificial intelligence chatbot (ChatGPT). METHODS: Five diseases from 8 subspecialties of Ophthalmology were assessed by ChatGPT version 3.5. Three questions were asked to ChatGPT for each disease: what is x?; how is x diagnosed?; how is x treated? (x = name of the disease). Responses were graded by comparing them to the American Academy of Ophthalmology (AAO) guidelines for patients, with scores ranging from -3 (unvalidated and potentially harmful to a patient's health or well-being if they pursue such a suggestion) to 2 (correct and complete). MAIN OUTCOMES: Accuracy of responses from ChatGPT in response to prompts related to ophthalmic health information in the form of scores on a scale from -3 to 2. RESULTS: Of the 120 questions, 93 (77.5%) scored ≥ 1. 27. (22.5%) scored ≤ -1; among these, 9 (7.5%) obtained a score of -3. The overall median score amongst all subspecialties was 2 for the question "What is x", 1.5 for "How is x diagnosed", and 1 for "How is x treated", though this did not achieve significance by Kruskal-Wallis testing. CONCLUSIONS: Despite the positive scores, ChatGPT on its own still provides incomplete, incorrect, and potentially harmful information about common ophthalmic conditions, defined as the recommendation of invasive procedures or other interventions with potential for adverse sequelae which are not supported by the AAO for the disease in question. ChatGPT may be a valuable adjunct to patient education, but currently, it is not sufficient without concomitant human medical supervision.

Use of the Patient Health Questionnaire-9 (PHQ-9) and Generalized Anxiety Disorder-7 (GAD-7) questionnaires for clinical decision-making and psychological referral in ophthalmic care: a multicentre observational study.

OBJECTIVES: The aim of this study was to evaluate the influence of anxiety and depression on clinician decision-making in patients suffering from chronic eye disease in ophthalmological clinical practice. DESIGN AND SETTING: This multicentre observational study, in collaboration with the WHO, included ophthalmologists and their patients affected by chronic eye disease. States of anxiety and depression were screened with specific questionnaires, the Patient Health Questionnaire-9 (PHQ-9) and Generalized Anxiety Disorder-7 (GAD-7), self-administered by patients before the visit. In the present analysis, we report data from three major eye care centres in Italy between 2021 and 2022. PRIMARY AND SECONDARY OUTCOMES: To assess self-reported changes in ophthalmologists' clinical approach (communication style and their clinical-therapeutic strategies) and decisions after knowing questionnaire scores (primary aim), and to analyse the PHQ-9 and GAD-7 scores in patients with chronic eye diseases (secondary aim). RESULTS: 41 ophthalmologists and 359 patients were included. The results from PHQ-9 and GAD-7 scores showed critical depression and anxiety status scores (PHQ-9 ≥5 and GAD-7 ≥10) in 258 patients. In 74% of cases, no actions were taken by the ophthalmologists based on these scores; in 26% of cases, they changed their clinical approach; and in 14% of cases, they referred the patients for psychological/psychiatric evaluation. CONCLUSIONS: States of anxiety and depression affect many patients with chronic eye conditions and need to be detected and managed early to improve patients' well-being. Providing ophthalmologists with knowledge of their patients' psychological conditions can change the clinical management and attitude towards referral for a psychological evaluation. Further studies are needed to expand our knowledge of how to raise awareness among ophthalmologists regarding multimorbidity of patients suffering from chronic eye diseases in order to achieve better clinical outcomes.

Finding Ophthalmic Risk and Evaluating the Value of Eye exams and their predictive Reliability (FOREVER)-A cohort study in a Danish high street optician setting: Design and methodology.

PURPOSE: The purpose of the study was to describe the rationale and design of Project FOREVER (Finding Ophthalmic Risk and Evaluating the Value of Eye exams and their predictive Reliability). DESIGN: Project FOREVER will build a comprehensive database of clinical eye and vision data collected from ~280 000 adults at 100 optician stores across Denmark. The FOREVER database (FOREVERdb) includes detailed data from refraction, visual acuity, intraocular pressure, corneal thickness, visual field assessments and retinal fundus images. Linkage to the comprehensive Danish national registries with, that is diagnostic and prescribing data permits investigation of rare associations and risk factors. 30 000 individuals over 50 also provide a saliva sample for later genetic studies and blood pressure measurements. Of these 30 000, 10 000 will also get optical coherence tomography (OCT) nerve and retinal scans. This subpopulation data is reviewed by ophthalmologists for disease detection. All participants will be asked to complete a questionnaire assessing lifestyle, self-perceived eye health and general health. Enrolment of participants began in April 2022. PERSPECTIVE: The FOREVERdb is a powerful tool to answer a wide range of research questions that can pave the way for better eye health. This database will provide valuable insights for future studies investigating the correlations between eye and general health in a Danish population cohort, enabling research to identify potential risk factors for a range of diseases.

Diagnostic genome sequencing improves diagnostic yield: a prospective single-centre study in 1000 patients with inherited eye diseases.

PURPOSE: Genome sequencing (GS) is expected to reduce the diagnostic gap in rare disease genetics. We aimed to evaluate a scalable framework for genome-based analyses 'beyond the exome' in regular care of patients with inherited retinal degeneration (IRD) or inherited optic neuropathy (ION). METHODS: PCR-free short-read GS was performed on 1000 consecutive probands with IRD/ION in routine diagnostics. Complementary whole-blood RNA-sequencing (RNA-seq) was done in a subset of 74 patients. An open-source bioinformatics analysis pipeline was optimised for structural variant (SV) calling and combined RNA/DNA variation interpretation. RESULTS: A definite genetic diagnosis was established in 57.4% of cases. For another 16.7%, variants of uncertain significance were identified in known IRD/ION genes, while the underlying genetic cause remained unresolved in 25.9%. SVs or alterations in non-coding genomic regions made up for 12.7% of the observed variants. The RNA-seq studies supported the classification of two unclear variants. CONCLUSION: GS is feasible in clinical practice and reliably identifies causal variants in a substantial proportion of individuals. GS extends the diagnostic yield to rare non-coding variants and enables precise determination of SVs. The added diagnostic value of RNA-seq is limited by low expression levels of the major IRD disease genes in blood.
