Giant cell arteritis is a challenging diagnosis for patients given the high prevalence of negative temporal artery biopsies (TAB). Despite the lack of histopathological evidence of giant cell arteritis in the TAB, patients can still have TAB-negative giant cell arteritis. The purpose of this paper is to analyse the predictors for TAB-negative giant cell arteritis and the alternative diagnosis of biopsy-negative patients without a giant cell arteritis diagnosis. A retrospective electronic database review of all TABs performed at the Royal Victorian Eye and Ear Hospital from February 2015 to May 2020. Logistic regression analysis was performed to determine predictive factors for a diagnosis of TAB-negative giant cell arteritis. In all cases, a clinical diagnosis of TAB-negative giant cell arteritis was determined by a neuro-ophthalmologist. Alternative diagnoses for negative TABs were identified and explored. A total of 368 TABs were analysed with 287 (78%) negative for histopathological evidence of GCA. Twenty-seven (9.4%) patients were diagnosed and treated as TAB-negative giant cell arteritis. The clinical predictors of a TAB-negative giant cell arteritis diagnosis were the presence of jaw claudication (OR 2.77, 95% CI 1.10-6.98) and CRP (OR 1.02, 95% CI 1.00-1.03). Alternative diagnoses included non-specific headache, non-arteritic anterior ischaemic optic neuropathy, retinal vessel occlusions, and ocular nerve palsies. Predictive factors for a diagnosis of TAB-negative giant cell arteritis were jaw claudication and an elevated CRP. Several alternative diagnoses can be considered for patients with a negative TAB in a neuro-ophthalmology context.

Most cases of optic neuritis (ON) occur in women and in patients between the ages of 15 and 45 years, which represents a key demographic of individuals who seek health information using the internet. As clinical providers strive to ensure patients have accessible information to understand their condition, assessing the standard of online resources is essential. To assess the quality, content, accountability, and readability of online information for optic neuritis. This cross-sectional study analyzed 11 freely available medical sites with information on optic neuritis and used PubMed as a gold standard for comparison. Twelve questions were composed to include the information most relevant to patients, and each website was independently examined by four neuro-ophthalmologists. Readability was analyzed using an online readability tool. Journal of the American Medical Association (JAMA) benchmarks, four criteria designed to assess the quality of health information further were used to evaluate the accountability of each website. Freely available online information. On average, websites scored 27.98 (SD ± 9.93, 95% CI 24.96-31.00) of 48 potential points (58.3%) for the twelve questions. There were significant differences in the comprehensiveness and accuracy of content across websites ( < .001). The mean reading grade level of websites was 11.90 (SD ± 2.52, 95% CI 8.83-15.25). Zero websites achieved all four JAMA benchmarks. Interobserver reliability was robust between three of four neuro-ophthalmologist (NO) reviewers (ρ = 0.77 between NO3 and NO2, ρ = 0.91 between NO3 and NO1, ρ = 0.74 between NO2 and NO1; all < .05). The quality of freely available online information detailing optic neuritis varies by source, with significant room for improvement. The material presented is difficult to interpret and exceeds the recommended reading level for health information. Most websites reviewed did not provide comprehensive information regarding non-therapeutic aspects of the disease. Ophthalmology organizations should be encouraged to create content that is more accessible to the general public.

Ophthalmologists' diagnostic and treatment competence in Acanthamoeba keratitis varies widely. This investigator-initiated, retrospective, single-center chart review examined the electronic patient files regarding PCR-positive Acanthamoeba keratitis. We included corneal and contact lens assessments. We further reviewed the patient's medical history, corneal scraping results regarding viral or fungal co-infections, and the duration from symptom onset to final diagnosis. We identified 59 eyes of 52 patients from February 2010 to February 2023, with 31 of 52 (59.6%) being female patients. The median (IQR, range) patient age was 33 (25.3 to 45.5 [13 to 90]) years, and the mean (SD, range) time to diagnosis after symptom onset was 18 (10.5 to 35 [3 to 70]) days. Overall, 7 of 52 (7.7%) patients displayed a bilateral Acanthamoeba infection, and 48 (92.3%) used contact lenses at symptom onset. Regarding other microbiological co-infections, we found virologic PCR testing in 45 of 52 (86.5%) patients, with 3 (6.7%) positive corneal scrapings. Fungal cultures were performed in 49 of 52 (94.2%) patients, with 5 (10.2%) positive corneal scrapings. The medical treatment success rate was 45/46 (97.8%). This study raises awareness of patient education in contact lens handling and screens for further microbial co-infections in suspected Acanthamoeba cases.

Color vision deficiency (CVD) is an often-overlooked issue within the medical community, and its consequences remain insufficiently explored. We aim to evaluate how CVD affects diagnostic accuracy and distinguish between malignant choroidal melanoma and benign choroidal nevus among ophthalmologists. In this cross-sectional study, we engaged ophthalmologists through a web-based survey distributed via the professional ophthalmology society's social media channels. The survey encompassed a series of three fundus images representing normal fundus, choroidal nevus, and choroidal melanoma. Each image underwent simulation for the three primary types of CVD-protanopia, deuteranopia, and tritanopia-alongside a non-simulated version. The study included 41 participants, averaging 40 years of age (±9.2), comprising 28 (68%) men and 13 (32%) women. Significantly lower rates of identifying orange pigments were observed in simulated protanopia images compared to non-simulated ones ( = 0.038). In simulated deutranopia images, the recognition of melanotic lesions was notably reduced compared to non-simulated images ( = 0.048). No such limitation was observed for tritanopia. However, participants retained their ability to identify subretinal fluid and estimate tumor thickness in simulated and non-simulated images. Concerning simulated images of choroidal nevi, participants misdiagnosed nevi as choroidal melanoma in 37% of cases in simulated protanopia nevi images and 41% in simulated deutranopia nevi images. This resulted in unnecessary referrals of benign lesions as malignant, emphasizing the potential for mistaken diagnoses. Nevertheless, almost all simulated images of malignant melanoma were correctly referred for specialized oncological treatment. The simulated CVD conditions of protanopia and deuteranopia affected the accuracy of identifying the melanotic nature of the choroidal tumor and the presence of orange pigments. This limitation led to challenges in correctly diagnosing choroidal melanoma and choroidal nevus, resulting in extra referrals for nevus cases. However, participants were safe and could still determine the possible risk of eyes with choroidal melanoma, so most referred melanoma cases to specialized oncologists as needed.

We present a case of bilateral endogenous endophthalmitis with an extremely rare etiology of . A 42-year-old asplenic patient with bilateral deterioration of visual acuity presented to the Emergency Department. The sudden deterioration of visual acuity, which prompted the patient to visit the ophthalmologist, was the first sign of the onset of sepsis. The physicians' attention, in addition to poor visual acuity and intense inflammation on ophthalmologic examination, was drawn to the reported flu-like symptoms. They were accompanied by high C-reactive protein results and abnormalities in echocardiography. A blood culture isolated the bacterium Immunocompromised patients are particularly susceptible to infection. Endophthalmitis of this etiology has a very aggressive course, both ophthalmic and systemic. Therefore, quick diagnosis and initiation of adequate therapy are crucial.

BACKGROUND
Large language models (LLMs) are becoming increasingly important as they are being used more frequently for providing medical information. Our aim is to evaluate the effectiveness of electronic artificial intelligence (AI) large language models (LLMs), such as ChatGPT-4, BingAI, and Gemini in responding to patient inquiries about retinopathy of prematurity (ROP).
METHODS
The answers of LLMs for fifty real-life patient inquiries were assessed using a 5-point Likert scale by three ophthalmologists. The models' responses were also evaluated for reliability with the DISCERN instrument and the EQIP framework, and for readability using the Flesch Reading Ease (FRE), Flesch-Kincaid Grade Level (FKGL), and Coleman-Liau Index.
RESULTS
ChatGPT-4 outperformed BingAI and Gemini, scoring the highest with 5 points in 90% (45 out of 50) and achieving ratings of "agreed" or "strongly agreed" in 98% (49 out of 50) of responses. It led in accuracy and reliability with DISCERN and EQIP scores of 63 and 72.2, respectively. BingAI followed with scores of 53 and 61.1, while Gemini was noted for the best readability (FRE score of 39.1) but lower reliability scores. Statistically significant performance differences were observed particularly in the screening, diagnosis, and treatment categories.
CONCLUSION
ChatGPT-4 excelled in providing detailed and reliable responses to ROP-related queries, although its texts were more complex. All models delivered generally accurate information as per DISCERN and EQIP assessments.

Review
Eales' Disease is an idiopathic peripheral retinal vasculopathy first described by British ophthalmologist Henry Eales in 1880. Most prevalent in healthy young males, Eales' Disease often presents with symptoms of sudden blurry or decreased vision and floaters. Although no clear, standardized stage of the disease exists, it progresses through three overlapping phases-peripheral periphlebitis, ischemic capillary ischemia, and retinal neovascularization. The etiology of Eales' Disease is unknown and appears to be multifactorial, but post-TB hypersensitivity to tuberculoprotein and DNA is the most potential cause in the etiology of Eales' Disease. With a thorough examination of the clinical presentation and diagnosis of Eales' Disease-incorporating the latest clinical findings related to the condition-the investigation for Eales' Disease extends to explore recent potential connections with other ocular conditions or possible cofactors, such as glaucoma, uncontrolled diabetes, drug abuse, or inherited medical conditions. Moreover, focusing on critical insights into the treatment of Eales' Disease across its various stages of progression, the overarching goal of the paper is to refine and suggest possible future diagnostic and therapeutic strategies. Widening our understanding of pathophysiology and utilizing various treatment options for individual patients holds immense potential for advancing ocular medicine and optimizing patient care for people with this disease with unknown pathophysiology.

PURPOSE OF REVIEW
The purpose of this review is to evaluate the current state of eco-sustainability in ophthalmology, highlighting key practices, recent advancements, and areas requiring improvement. This review aims to provide ophthalmologists with a comprehensive overview of sustainable practices that can reduce environmental impact.
RECENT FINDINGS
Recent studies have identified several areas within ophthalmology where sustainable practices can be implemented including multidose eyedrops, adjusting surgical packs, making package inserts available electronically, and reusing surgical instruments. Moreover, there is an increasing emphasis on waste reduction both in the surgical and clinical setting, by decreasing the use of unnecessary materials and implementing more efficient use of recycling programs. Telemedicine has also emerged as a sustainable option, reducing the carbon footprint associated with patient travel. Despite these advancements, significant challenges remain, particularly in balancing the cost and accessibility of sustainable options with traditional practices.
SUMMARY
Eco-sustainability in ophthalmology is gaining momentum as the medical community aims to reduce its environmental impact. While progress has been made, further efforts are required to overcome financial and logistical barriers to widespread implementation. Continued research, education, and policy development are essential to advancing eco-sustainable practices, ensuring that environmental considerations become an integral part of ophthalmic care.

PURPOSE OF REVIEW
This review aims to enhance understanding of juvenile Sjögren's disease (jSjD) by exploring diagnostic criteria, ocular clinical features, ancillary ophthalmic testing, and management strategies specific to this rare pediatric condition.
RECENT FINDINGS
Unlike adults, children with jSjD often present with recurrent parotitis and extra-glandular symptoms before developing sicca symptoms. Adult SjD classification criteria do not consider pediatric-specific symptoms and physiological differences. Underutilization of diagnostic tests such as the ocular staining score (OSS) and Schirmer I may result in an incomplete understanding of the prevalence of keratoconjunctivitis sicca in jSjD.
SUMMARY
Timely referral to an ophthalmologist can address perceived feasibility issues with respect to ocular features in jSjD. Management of keratoconjunctivitis sicca in jSjD includes improving ocular surface lubrication and decreasing inflammation. Recognition of pediatric-specific clinical features and development of universally accepted jSjD classification criteria will allow for better identification of potential participants for future jSjD studies.

PURPOSE
This study investigated the distribution of fundus tessellation density (FTD) in a Chinese pediatric population and its potential in reflecting early myopic maculopathy (tessellated fundus).
METHODS
Participants were enrolled from kindergartens, primary schools, and middle schools, with cluster sampling in Shanghai, China. A series of ophthalmic examinations was conducted. Based on fundus photograph, FTD was quantitatively assessed using an artificial intelligence algorithm, and tessellated fundus was diagnosed by well-trained ophthalmologists.
RESULTS
A total of 14,234 participants aged four to 18 years were included, with 7421 boys (52.1%). Tessellated fundus was observed in 2200 (15.5%) participants. The median of FTD was 0.86% (range 0.0-42.1%). FTD increased with age and axial length. In the logistics regression, larger FTD was independently associated with tessellated fundus (P < 0.001). The area under curves of receiver operating characteristic curve for categorizing tessellated fundus using FTD was 0.774, and the cutoff point of FTD was 2.22%.
CONCLUSIONS
The density of fundus tessellation was consistent with the severity of myopia. FTD could help diagnose the early stage of myopic maculopathy, tessellated fundus, providing a new pattern for myopia screening and detection of early myopic fundus changes.
TRANSLATIONAL RELEVANCE
Quantification of fundus tessellation with artificial intelligence could help detect early myopic maculopathy.
