RESUMEN
Assessing anterior chamber inflammation is highly subjective and challenging. Although various grading systems attempt to offer objectivity and standardization, the clinical assessment has high interobserver variability. Traditional techniques, such as laser flare meter and fluorophotometry, are not widely used since they are time-consuming. With the development of optical coherence tomography with high sensitivity, direct imaging offers an excellent alternative to assess objectively inflammation with the potential for automated analysis. We describe various anterior chamber inflammation grading methods and discuss their utility, advantages, and disadvantages.

PURPOSE: To assess the diagnostic performance of two chatbots, ChatGPT and Glass, in uveitis diagnosis compared to renowned uveitis specialists, and evaluate clinicians' perception about utilizing artificial intelligence (AI) in ophthalmology practice. METHODS: Six cases were presented to uveitis experts, ChatGPT (version 3.5 and 4.0) and Glass 1.0, and diagnostic accuracy was analyzed. Additionally, a survey about the emotions, confidence in utilizing AI-based tools, and the likelihood of incorporating such tools in clinical practice was done. RESULTS: Uveitis experts accurately diagnosed all cases (100%), while ChatGPT achieved a diagnostic success rate of 66% and Glass 1.0 achieved 33%. Most attendees felt excited or optimistic about utilizing AI in ophthalmology practice. Older age and high level of education were positively correlated with increased inclination to adopt AI-based tools. CONCLUSIONS: ChatGPT demonstrated promising diagnostic capabilities in uveitis cases and ophthalmologist showed enthusiasm for the integration of AI into clinical practice.
RESUMEN
Severe mechanical ocular trauma with no light perception (NLP) predicts a poor prognosis of visual acuity and enucleation of the eyeball. Since the innovative treatment concept of exploratory vitreoretinal surgery has developed and treatment technology has advanced, the outcomes of severe ocular trauma treatment in NLP patients have greatly improved. However, there remains a lack of unified standards for the determination, surgical indication, and timing of vitrectomy in NLP eye treatment. To address these problems, we aimed to create evidence-based medical guidelines for the diagnosis, treatment, and prognosis of mechanical ocular trauma with NLP. Sixteen relevant recommendations for mechanical ocular trauma with NLP were obtained, and a consensus was reached. Each recommendation was explained in detail to guide the treatment of mechanical ocular trauma associated with NLP.

Importance: Ocular trauma terminology should be periodically updated to enable comprehensive capturing and monitoring of ocular trauma in clinical and research settings. Objective: To update terminology for globe and adnexal trauma. Design, Setting, and Participants: A 2-round modified Delphi survey was conducted from January 1 to July 31, 2021, using an expert panel, including 69 ophthalmologists identified through their membership in ophthalmology (globe and adnexal trauma) societies. Consensus was defined as at least 67% expert agreement. A steering committee developed questions after identifying gaps in the current terminology via a targeted literature review. Round 1 sought consensus on existing and newly proposed terminology, and round 2 focused on unresolved questions from round 1. Experts included ophthalmologists who had managed, on average, 52 globe or adnexal trauma cases throughout their careers and/or published a total of 5 or more globe or adnexal trauma-related peer-reviewed articles. Main Outcomes and Measures: Expert consensus on ocular and adnexal terms. Results: A total of 69 experts participated in and completed round 1 of the survey. All 69 participants who completed round 1 were asked to complete round 2, and 58 responses were received. Consensus was reached for 18 of 25 questions (72%) in round 1 and 4 of 7 questions (57%) in round 2. Existing Birmingham Eye Trauma Terminology system terminology achieved consensus of 84% (58 of 69 experts) in round 1 and 97% (56 of 58 experts) in round 2. Experts agreed on the need for further refinement of the definition of zones of injury (55 of 69 [80%]), as the zone affected can have a substantial effect on visual and functional outcomes. There was consensus that the mechanism of injury (52 of 69 [75%]) and status of the lacrimal canaliculi (54 of 69 [78%]), nasolacrimal ducts (48 of 69 [69%]), lens (46 of 58 [80%]), retina (42 of 58 [73%]), and central and paracentral cornea (47 of 58 [81%]) be included in the revised terminology. Conclusions and Relevance: There was consensus (defined as at least 67% expert agreement) on continued use of the existing Birmingham Eye Trauma Terminology system definitions and that additional terms are required to update the current ocular trauma terminology.

Ophthalmic trauma is a leading cause of preventable monocular blindness worldwide. The prevalence of ophthalmic trauma varies considerably based on geographic location, socio-economic status, age groups, occupation, and cultural practices such as firework celebrations. Clinical registries are known to be valuable in guiding the diagnosis, management, and prognostication of complex diseases. However, there is currently a lack of a centralized international data repository for ophthalmic trauma. We draw lessons from past and existing clinical registries related to ophthalmology and propose a new suitable international multicenter clinical registry for ophthalmic trauma: the International Globe and Adnexal Trauma Epidemiology Study (IGATES). IGATES is hosted on a secure web-based platform which exhibits user-friendly smart features, an integrated Ocular Trauma Score (OTS) prognosis calculator, efficient data collection points, and schematic graphical software. IGATES currently has 37 participating centers globally. The data collected through IGATES will be primarily used to develop a more robust and improved ophthalmic trauma prognostic classification system, the Ocular Trauma Score-2 (OTS-2), which builds on previous systems such as the Birmingham Eye Trauma Terminology System (BETTS) and Ocular Trauma Score (OTS). Furthermore, IGATES will act as a springboard for further research into the epidemiology, diagnosis, and management of ophthalmic trauma. Ultimately, IGATES serves to advance the field of ophthalmic trauma and improve the care that patients with ophthalmic trauma receive.

INTRODUCTION: To elucidate the perceptions on eye care of patients affected by the disruption of outpatient and surgical ophthalmological services during the COVID-19 pandemic. METHODS: A cross-sectional questionnaire-based survey was conducted during the reopening of outpatient services at two tertiary eye care centres in Singapore and North India. Consecutive patients were recruited from general and specialist eye clinics in June 2020. RESULTS: A total of 326 patients were recruited, 200 patients from Singapore and 126 patients from New Delhi, India. The most common eye conditions were diabetic retinopathy and uveitis or ocular inflammatory conditions in the Indian centre, whereas the most common in the Singaporean centre were cataract in the pre- or postoperative stage and glaucoma. For patients from the Indian centre, 61.9% felt that COVID-19 had negatively impacted their eye disease, 58.7% were more distressed by their eye disease, 70.8% could not access appropriate eye care, 66.6% were afraid of contracting COVID-19 in the clinic, and 61.9% were accepting of teleconsultations. For patients from the Singaporean centre, 13.5% felt that COVID-19 had negatively impacted their eye disease, 19.5% were more distressed by their eye disease, 21.5% could not access appropriate eye care, 35% were afraid of contracting COVID-19 in the clinic, and only 31% were accepting of teleconsultations. CONCLUSION: Patients from India appear to have been more negatively affected by the pandemic compared to patients from Singapore. This study highlights patients' perceptions of the impact of COVID-19 on eye care, perceived risks, ease of access to care and attitudes towards eye care during the pandemic. Patients' perceptions are integral in developing strategies for the best care possible. There were heterogeneous responses amongst our patients; hence, there may be a role for more individualized healthcare strategies in the future.
RESUMEN
The COVID-19 pandemic has galvanized the global response towards the development of new vaccines based on novel technologies at an unprecedented pace. Since the widespread implementation of vaccination campaigns, case reports on vaccines' systemic side effects, including ocular manifestations, have emerged. Since administered vaccines are generally not able to cause the disease in the recipient, or induce an immune response against the pathogen, we hypothesize that the development of ocular phenomena post-COVID-19 vaccination may occur via an immune response elicited by the vaccine. Of many, the most common ocular adverse events include facial nerve palsy, central venous sinus thrombosis and acute anterior uveitis. These COVID-19 vaccine-induced ocular (CVIO) adverse events could resemble the ocular findings in some of the COVID-19 patients. This review will provide a comprehensive overview of published ocular side effects potentially associated with COVID-19 vaccination and serve as a springboard for further research into CVIO adverse events.
RESUMEN
PURPOSE: To report on the factors associated with severe vision loss from fireworks-related ocular trauma during celebrations, including festivals. METHODS: Tertiary eye care hospitals in 5 countries and private ophthalmology practices in the Netherlands. Patients included received treatment for fireworks-related ocular trauma during celebrations. Demographic and clinical data for patients affected were analyzed and associations with severe vision loss reported. RESULTS: Of 388 patients, 71 (18.3 %) had severe vision loss (worse than 6/60) at 4-week follow-up due to fireworks-related ocular trauma. Mean age overall was 20.6 years (range 2 to 83 years), and there was a male predominance of 4:1. Clinical factors associated with severe vision loss included penetrating injury (OR 4.874 [95% CI 1.298-18.304; p = 0.02]) and lens injury (OR 7.023 [95% CI 2.378-20.736; p = 0.0004]). More patients with closed-globe injuries (CGIs) had improved vision after 4 weeks (OR 3.667, 1.096-12.27) compared to those with open-globe injuries (OGI) (p = 0.035). Eye protection use was reported by 7 patients, and 39.4% patients < 18 years were unsupervised by an adult at the time of injury. CONCLUSIONS: Severe vision loss from fireworks-related ocular trauma occurred during celebrations in a variety of countries and was associated with penetrating and/or lens injury and poor presenting vision. New initiatives are needed to prevent severe vision loss associated with these injuries.

PURPOSE: To detail the methodology for a novel ocular trauma registry and utilize the registry to determine the demographics, nature of injury, and associations of severe visual loss for open globe injuries (OGI). METHODS: Thirteen hospitals in 7 countries used International Globe and Adnexal Trauma Epidemiology Study (IGATES) platform. Patients presenting between April 2009 and 2020 with OGI (with or without) adnexal involvement or intraocular foreign body (IOFB) were included. RESULTS: Analyses of presenting and final VA, using "severe vision loss" (VA ≤ 6/60) and "no severe loss" (VA > 6/60), were performed. Four hundred fifty-four (64%) patients had VA < 6/60 at presentation and 327 (44.8%) at final follow-up, with a highly significant association between presenting and final VA (p < 0.0001). From the cohort of 746 patients, 37 were missing VA at presentation and 16 at follow-up and complete clinical data was available for 354 patients. The male to female ratio is 6:1, and mean age 36.0 ± 20.0 years old. Relative afferent pupillary defect (RAPD), zone III injury, IOFB, and eyelid injury at presentation were recorded in 50 (6.7%), 55 (7.8%), 97 (13%), and 87 (11.7%) patients, respectively, and were significantly associated with VA < 6/60 at follow-up. Older age, ≥ 61 years, was associated with 3.39 times (95% CI: 1.95-5.89) higher risk than ≤20-year-old patients (p < 0.0001) and males 0.424 times (95% CI: 0.27-0.70) lower risk than female (p = 0.0001) of severe vision loss (SVL). CONCLUSION: In OGIs from 13 hospitals, female gender, older age, zone III injury, eyelid injury, and IOFB were associated with higher risk of visual outcome of SVL.

Unclear pathogenic mechanisms underlying the ocular tuberculosis (OTB) has resulted in perplexity related to the diagnosis and management of the disease. Developments in experimental research and innovations in molecular diagnostics have recently provided a new understanding of disease pathogenesis and natural history. The current review focuses on the new insights into OTB pathogenesis, derived from in vivo and in vitro studies on Mycobacterium tuberculosis dissemination and localization into the eye, in combination with histopathological studies on chorioretinal tissue and vascular network. Advances in the knowledge of OTB have influenced disease management in the clinical setting and lead to reconsideration of the role of existing treatments and suggesting potential new therapeutic approaches.

An international, expert led consensus initiative was set up by the Collaborative Ocular Tuberculosis Study (COTS) group to develop systematic, evidence, and experience-based recommendations for the treatment of ocular TB using a modified Delphi technique process. In the first round of Delphi, the group identified clinical scenarios pertinent to ocular TB based on five clinical phenotypes (anterior uveitis, intermediate uveitis, choroiditis, retinal vasculitis, and panuveitis). Using an interactive online questionnaires, guided by background knowledge from published literature, 486 consensus statements for initiating ATT were generated and deliberated amongst 81 global uveitis experts. The median score of five was considered reaching consensus for initiating ATT. The median score of four was tabled for deliberation through Delphi round 2 in a face-to-face meeting. This report describes the methodology adopted and followed through the consensus process, which help elucidate the guidelines for initiating ATT in patients with choroidal TB.
RESUMEN
The choroid is one of the most vascularized structures of the human body and plays an irreplaceable role in nourishing photoreceptors. As such, choroidal dysfunction is implicated in a multitude of ocular diseases. Studying the choroid can lead to a better understanding of disease pathogenesis, progression and discovery of novel management strategies. However, current research has produced inconsistent findings, partly due to the physical inaccessibility of the choroid and the lack of reliable biomarkers. With the advancements in optical coherence tomography technology, our group has developed a novel quantitative imaging biomarker known as the choroidal vascularity index (CVI), defined as the ratio of vascular area to the total choroidal area. CVI is a potential tool in establishing early diagnoses, monitoring disease progression and prognosticating patients. CVI has been reported in existing literature as a robust marker in numerous retinal and choroidal diseases. In this review, we will discuss the current role of CVI with reference to existing literature, and make postulations about its potential and future applications.

Purpose: Collaborative Ocular Tuberculosis Study (COTS)-1 aims to address knowledge deficits through collaboration amongst uveitis specialists across the globe by sharing the data of patients with TBU presented at participating centers from January 2004 to December 2014. Methods: Data collection was facilitated by a novel method of real-time encrypted web-based data entry allowing regular updates as new data and recommendations become available. Results: Information on clinical features, investigation findings, management, and treatment outcomes were reviewed to get an idea about real world scenario. Conclusion: The current review aims to focus on methodology and briefing of published reports from COTS group in COTS-1 study to highlight key messages from this large data.
RESUMEN
Purpose: To contribute a global description of the spectrum of choroidal involvement in tubercular uveitis (TBU).Methods: Retrospective cohort study of TBU patients with choroidal involvement from 25 centers between January 2004 and December 2014. Medical records of patients with a minimum follow-up of 1 year were reviewed.Results: 245 patients were included. The phenotypic variations included serpiginous-like choroiditis (SLC) (46%), tuberculoma (13.5%), multifocal choroiditis (MFC) (9.4%), ampiginous choroiditis (9%), among others. 219 patients were treated with anti-tubercular therapy (ATT) (n = 219/245, 89.38%), 229 patients with steroids (n = 229/245, 93.47%) and 28 patients with immunosuppressive agents (n = 28/245, 11.42%). Treatment failure was noted in 38 patients (n = 38/245, 15.5%). Patients with SLC and ampiginous choroiditis appeared to have superior outcomes on survival analysis (p = 0.06).Conclusion: This study provides a comprehensive description of choroidal involvement in TBU. Patients with SLC and ampiginous choroiditis may have better clinical outcomes.
RESUMEN
Fireworks are an integral aspect of national, cultural and religious festivals globally, featuring in a vast range of celebrations including Diwali in India and New Year's Eve in the USA. We have seen a trend in eye injuries related to the use of fireworks, with millions of people, of which a large proportion comprising children, are injured annually-and rather than falling, as one would hope, this number is remaining stable. A comprehensive study of the impact of firework-related injuries to the eye is not available, and the efforts to mitigate this are not widely discussed in the literature. This literature review therefore focusses on studying the impact of firework-related eye injuries, the effect of legislation on mitigating these injuries and their associated morbidity.
