Ocular lesions in patients with ulcerative colitis.

OBJECTIVE: Aim: To analyze the data and evaluate the prevalence of ocular lesions in patients with moderate ulcerative colitis. PATIENTS AND METHODS: Materials and Methods: We observed 112 patients aged 18-75 years old with clinically, endoscopically and histologically confirmed moderate ulcerative colitis which lasted at least 6 months. An ophthalmologic exam was performed to determine the presence of ocular symptoms. RESULTS: Results: Of the 112 patients with moderate ulcerative colitis, 21 (18,75%) had the following ocular lesions: episcleritis - 7 patients (6,25%), keratopathy - 5 patients (4,46%), uveitis - 5 patients (4,46%), cataract - 2 (1,78%) and scleritis - 2 (1.78%). CONCLUSION: Conclusions: Because ocular symptoms in patients with UC are often nonspecific, it may be beneficial to perform ophthalmologic examinations as a routine follow-up component of in such patients.

[Extra-intestinal manifestations associated with Crohn's disease]. / Extra-intestinale uitingen van inflammatoire darmziekte.

Extra-intestinal manifestations (EIM) associated with Crohn's disease (CD) are frequently observed and can manifest as either the initial symptom or develop later in the disease course following gastrointestinal symptoms. The most common EIM affect the joints, skin, or eyes, with some correlating with active CD activity while others may occur during periods of inactivity. EIM can affect both pediatric and adult CD patients, potentially reducing their quality of life if not promptly identified and treated. Thus, emphasizing the prevalence and clinical presentation is essential to initiate appropriate diagnostic assessments and effectively treat both EIM and the underlying CD. In this case series, we present two pediatric and one adult case where EIM preceded CD diagnosis, resulting in delayed CD diagnosis. Additionally, we outline the most prevalent EIM, their epidemiology, and associated symptoms.

Myopia and Nutrient Associations with Age-Related Eye Diseases in Korean Adults: A Cross-Sectional KNHANES Study.

This study assessed the prevalence of myopia, cataracts, glaucoma, and macular degeneration among Koreans over 40, utilizing data from the 7th Korea National Health and Nutrition Examination Survey (KNHANES VII, 2018). We analyzed 204,973 adults (44% men, 56% women; mean age 58.70 ± 10.75 years), exploring the association between myopia and these eye diseases through multivariate logistic regression, adjusting for confounders and calculating adjusted odds ratios (ORs) with 95% confidence intervals (CIs). Results showed a myopia prevalence of 44.6%, cataracts at 19.4%, macular degeneration at 16.2%, and glaucoma at 2.3%, with significant differences across ages and genders. A potential link was found between myopia and an increased risk of cataracts and macular degeneration, but not with glaucoma. Additionally, a higher dietary intake of carbohydrates, polyunsaturated and n-6 fatty acids, vitamins, and minerals correlated with lower risks of these diseases, underscoring the importance of the diet in managing and preventing age-related eye conditions. These findings highlight the need for dietary considerations in public health strategies and confirm myopia as a significant risk factor for specific eye diseases in the aging Korean population.

Exploring the role of the ocular surface in the lung-eye axis: Insights into respiratory disease pathogenesis.

Chronic respiratory diseases (CRDs) represent a significant proportion of global health burden, with a wide spectrum of varying, heterogenic conditions largely affecting the pulmonary system. Recent advances in immunology and respiratory biology have highlighted the systemic impact of these diseases, notably through the elucidation of the lung-eye axis. The current review focusses on understanding the pivotal role of the lung-eye axis in the pathogenesis and progression of chronic respiratory infections and diseases. Existing literature published on the immunological crosstalk between the eye and the lung has been reviewed. The various roles of the ocular microbiome in lung health are also explored, examining the eye as a gateway for respiratory virus transmission, and assessing the impact of environmental irritants on both ocular and respiratory systems. This novel concept emphasizes a bidirectional relationship between respiratory and ocular health, suggesting that respiratory diseases may influence ocular conditions and vice versa, whereby this conception provides a comprehensive framework for understanding the intricate axis connecting both respiratory and ocular health. These aspects underscore the need for an integrative approach in the management of chronic respiratory diseases. Future research should further elucidate the in-depth molecular mechanisms affecting this axis which would pave the path for novel diagnostics and effective therapeutic strategies.

Obesity, body fat distribution and eye diseases.

BACKGROUND: The prevalence of obesity, a chronic disease, is increasing, and obesity is now considered a global epidemic. Eye diseases are also increasing worldwide and have serious repercussions on quality of life as well as increasingly high costs for the community. The relationships between obesity and ocular pathologies are not yet well clarified and are not pathologically homogeneous: they seem to be somehow linked to excess body fat, especially to the distribution of adipose tissue and its ectopic deposits. PURPOSE: Our objective was to examine the associations between obesity and anthropometric indices, including body mass index (BMI), waist circumference (WC), and the waist/hip ratio (WHR), and the risk of most widespread eye diseases, with particular attention given to the most significant metabolic mechanisms. METHODS: This article provides a narrative overview of the effect of obesity and anthropometric measurements of body fat on prevalent eye diseases. We used the MEDLINE/PubMed, CINAHL, EMBASE, and Cochrane Library databases from 1984 to 2024. In addition, we hand-searched references from the retrieved articles and explored a number of related websites. A total of 153 publications were considered. RESULTS: There is significant evidence that obesity is associated with several eye diseases. Waist circumference (WC) and the waist/hip ratio (WHR) have been observed to have stronger positive associations with eye diseases than BMI. CONCLUSIONS: Obesity must be considered a significant risk factor for eye diseases; hence, a multidisciplinary and multidimensional approach to treating obesity, which also affects ocular health, is important. In the prevention and treatment of eye diseases related to obesity, lifestyle factors, especially diet and physical activity, as well as weight changes, both weight loss and weight gain, should not be overlooked. LEVEL OF EVIDENCE: Level V narrative review.

Ocular features of NGLY1 deficiency from a prospective longitudinal cohort.

BACKGROUND: NGLY1 deficiency is a rare autosomal recessive disorder with core features of global developmental delay, liver enzyme abnormalities, movement disorder, polyneuropathy, and hypo- or alacrima. We characterized the full spectrum and evolution of the ocular phenotype in a prospective natural history of NGLY1 deficiency. METHODS: We collected ophthalmological data on 29 individuals with NGLY1 deficiency in a natural history study. Medical records were reviewed to confirm caregiver-reported symptoms. Of the 29, 15 participants appeared for at least one ophthalmological examination. RESULTS: Caregivers reported at least one ocular sign or symptom in 90% of participants (26/29), most commonly decreased tears, refractive error, and chronic infection. Daily eye medication, including artificial tears, ophthalmic ointment, and topical antibiotics were used by 62%. Ophthalmological examination confirmed refractive errors in 93% (14/15) and corneal abnormalities in 73% (11/15). CONCLUSIONS: Given nearly universal hypolacrima and additional prominent ocular findings in NGLY1 deficiency, a targeted ocular history and ophthalmologic examination may facilitate prompt diagnosis and early initiation of preventive eye care, preserving vision and overall ocular health.

[OPHTHALMOLOGY - ON THE TIP OF THE SPEAR].

INTRODUCTION: Ophthalmology is a broad branch of medicine, which includes an extensive range of sub-specialties on one hand, and interfaces with other fields of medicine on the other. This issue contains papers from different sub-specialties of ophthalmology, that together cover several of the most important issues in this field. These papers present the topics in a manner compatible with the wide readership of the journal, and touch upon the most current updates and innovations. The original articles in this issue deal with treatments for the prevention of myopia progression in children, treatment of complicated cases of retinal detachment in children, ocular manifestations of vascular abnormalities in patients with coronavirus, and a series of patients with corneal damage due to ultraviolet-C (UVC) lamps intended to clear the air of this virus. The review papers describe glaucoma and the current change in its treatment paradigm, which focuses on earlier intervention, ocular manifestations of systemic autoimmune diseases, and the possibilities for artificial corneal implantation. We hope that this special issue will be of interest and clinical value to its readers.

No side effects on rabbit retina or vitreous microenvironment by nd:YAG laser vitreolysis.

BACKGROUND: To explore the safety of Neodymium:Yttrium-aluminum-garnet (Nd:YAG) laser vitreolysis based on the histological examination of the retina and the alteration of vitreous cytokines in the rabbits. METHODS: Nine male New Zealand rabbits underwent Nd:YAG laser vitreolysis of 10 mJ x 500 pulses in the left eyes, while the right eyes were used as controls. Intraocular pressure, color fundus photography, and ultrasound B scan were measured before, as well as 1 day, 4 weeks, and 12 weeks after Nd:YAG laser vitreolysis. Three rabbits were euthanized 1 day, 4 weeks, and 12 weeks after treatment, respectively. Terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) staining and hematoxylin-eosin (H&E) staining were used to look for pathological changes in the retina. An enzyme-linked immunosorbent assay (ELISA) was utilized to detect the expression of vascular endothelial growth factor (VEGF) and some inflammatory cytokines, including interferon inducible protein 10 (IP-10), monocyte chemoattractant protein 1 (MCP-1) and interlenkin 6 (IL-6) in the vitreous humor. The ascorbic acid (AsA) and total reactive antioxidant potential (TRAP) in the vitreous humor were also measured. RESULTS: Following Nd:YAG laser vitreolysis, the levels of VEGF, IP-10, MCP-1, IL6, AsA, and TRAP in the vitreous humor did not change substantially (P > 0.05). There were no detectable pathological changes in the retinal tissues, and no apoptotic signal was found. CONCLUSIONS: Rabbits tolerate Nd:YAG laser vitreolysis without observable impact on retinal tissue or the microenvironment of the vitreous.

Ocular Involvement in Selected Rheumatic Diseases - Clinical Manifestation in Adulthood. / Augenbeteiligung bei ausgewählten rheumatischen Erkrankungen ­ Klinik im Erwachsenenalter.

Ocular manifestations of rheumatic diseases are common and contribute significantly to the morbidity and reduced quality of life of affected patients. Knowledge of typical clinical manifestations is important for the rheumatologist in order to support the reference of patients with corresponding symptoms for ophthalmological consultation at an early stage of disease, or to initiate regular screening examinations (e.g. in patients with Behçet's syndrome). Conversely, a (possibly urgent) rheumatological assessment is crucial for certain ophthalmological diseases, in order not to overlook a (possibly fatal) systemic associated disease. Patients with rheumatic or inflammatory ocular diseases should always be informed by the treating physician about possible symptoms of other organ manifestations, in order to avoid a delayed diagnosis. "Classic" associations for uveitis are (HLA-B27-associated) spondyloarthritis and acute anterior uveitis, as well as retinal vasculitis with or without panuveitis and Behçet's syndrome. In patients with rheumatoid arthritis or ANCA-associated vasculitis, however, scleritis (with or without peripheral ulcerative keratitis) typically occurs, but a variety of other findings are also possible. Close interdisciplinary collaboration, particularly regarding therapeutic decisions, is crucial to ensuring a good prognosis for the patient.

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.

Ocular adverse events following CAR-T cell therapy: A pharmacovigilance study and systematic review.

The rise of immuno-oncology, including the use of chimeric antigen receptor T-cell (CAR-T) therapy is bringing in a new wave of cancer treatments, particularly in hematologic malignancies. However, data on their adverse events, particularly of the eye, is under-reported. To assess the ocular adverse events associated with the six FDA-approved CAR-T cell therapies, a disproportionality analysis utilizing the FAERS database was conducted from the first quarter of 2017 to the third quarter of 2023, as well as a systematic review of case reports of ocular events following CAR-T cell therapy up to December 20, 2023. A total of 53 ocular adverse events were identified from the FDAs FAERS database. The adverse events most frequently observed were mydriasis and xerophthalmia with tisagenlecleucel (Kymriah). The systematic review resulted in 8 case reports encompassing 19 patients which included a total of 27 events. This study demonstrates the importance of anticipation of potential ocular adverse events by ophthalmologists and oncologists as they can greatly contribute to morbidity in patients with cancer.

Ocular and orbital manifestations in VEXAS syndrome.

BACKGROUND: VEXAS (Vacuoles, E1 enzyme, X-linked, Autoinflammatory, Somatic) is a hematoinflammatory disease that typically affects adults. It results from a somatic mutation of the E1 ubiquitin conjugating enzyme encoded by the UBA1 gene. VEXAS is frequently accompanied by myelodysplastic syndrome (MDS). The purpose of this study is to describe the ocular and orbital manifestations of VEXAS patients in a case series in our medical centre. METHODS: A retrospective chart review was performed for all patients who were diagnosed with VEXAS syndrome in a tertiary medical centre over two years. RESULTS: Eight patients were identified with VEXAS. In six patients, the diagnosis was confirmed by genomic sequencing. Two patients were identified based on their phenotype. All patients were males. The mean age at diagnosis was 78.7 years. In two patients, the ocular manifestation was the presenting symptom for VEXAS. Seven patients (87.5%) had history of MDS. Systemic inflammation manifestations include: skin rash (n = 5), recurrent fevers (n = 2), relapsing polychondritis (n = 2), pleuritis and pleural effusion (n = 2), poly arteritis nodosa- PAN (n = 1) and thrombophlebitis (n = 1). Seven (87%) patients were presented with periorbital oedema. Three patients showed orbital inflammation. Dacryoadenitis was observed in two patients, and extraocular muscle (EOM) myositis was detected in two patients. Four patients demonstrated ocular inflammation such as: episcleritis, scleritis and anterior uveitis. CONCLUSION: ocular manifestations in VEXAS include orbital inflammation, dacryoadenitis, myositis, uveitis, scleritis, episcleritis and periorbital oedema. We recommend that in old male patients, with history of haematological disorder, presenting with ocular symptom, VEXAS investigation should be taken into consideration.

Ophthalmic manifestations of nasopharyngeal carcinoma (NPC): A systematic review of reported cases with and without prior history of nasopharyngeal carcinoma.

PURPOSE: We aimed to study reported cases of nasopharyngeal carcinoma presenting with ophthalmic manifestations with and without a prior diagnosis of nasopharyngeal carcinoma. METHODS: We conducted a systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). A literature search was conducted using the MEDLINE database in PubMed and Google Scholar. We included patients with a previous diagnosis of nasopharyngeal carcinoma in Group I and those without a prior diagnosis of nasopharyngeal carcinoma in Group II. Data included demographics, clinical presentation, history of nasopharyngeal carcinoma, treatment, histopathological description, World Health Organization classification, and outcome. RESULTS: Fifty-eight patients (26 in Group I and 32 in Group II) were included. The male-to-female ratio was 3:1. The mean age of the patients (53.3 ± 11.7 years and 54.8 ± 16.2 years, respectively) and gender did not differ significantly between the two groups. The most common ocular presentations were diplopia and proptosis in the first group (each in 34.6%), whereas visual disturbance was most common in the second group (46.9%). Treatment options and World Health Organization grading were comparable. The outcome in 38 patients (after a comparable follow-up period) was significantly better in group II (p=0.003). There was no statistically significant difference in the outcome of 23 patients in correlation with World Health Organization grades II versus III irrespective of group (p=0.094). CONCLUSIONS: The demographics of patients with nasopharyngeal carcinoma presenting with ophthalmic manifestations were similar between the two study groups, with a wide age range and male predominance. Patients presenting initially to ophthalmologists with no history of nasopharyngeal carcinoma have a more favorable outcome. World Health Organization grading may have less value as a prognostic indicator.

Management of Primary Sclerosing Cholangitis and Extraintestinal Disorders in Patients With Ileal Pouches: A Systematic Review.

BACKGROUND: Restorative proctocolectomy with IPAA improves the quality of life in patients with ulcerative colitis by the removal of diseased large bowel and preservation of the natural route of defecation. Although the surgery may improve preexisting extraintestinal manifestations in the joints, skin, and eyes, extraintestinal manifestations, particularly primary sclerosing cholangitis, can persist after colectomy. OBJECTIVES: A systematic review of diagnosis and treatment of liver, joint, skin, and eye manifestations in patients with restorative proctocolectomy and IPAA for ulcerative colitis. DATA SOURCES: PubMed, Google Scholar, and Cochrane database. STUDY SELECTION: Relevant articles on primary sclerosing cholangitis and extraintestinal manifestations in ileal pouches published between January 2001 and July 2023 in English were included on the basis of Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. INTERVENTION: Diagnosis and treatment of primary sclerosing cholangitis and extraintestinal manifestations in patients with restorative proctocolectomy and IPAA were included. MAIN OUTCOME MEASURES: Association between primary sclerosing cholangitis, extraintestinal manifestations, and inflammatory disorders of the pouch and their management. RESULTS: Primary sclerosing cholangitis and extraintestinal manifestations are associated with pouchitis, particularly chronic pouchitis. Primary sclerosing cholangitis is associated with chronic pouchitis, enteritis, and possible pouch neoplasia. However, the disease severity and course of primary sclerosing cholangitis and pouchitis do not appear to be parallel. Despite the fact that oral vancomycin or budesonide have been used to treat primary sclerosing cholangitis-associated pouchitis, their impact on the disease course of primary sclerosing cholangitis is not known. Biological therapy for chronic inflammatory disorders of the pouch may also be beneficial for the concurrent extraintestinal manifestations of the joints, skin, and eyes. However, studies on the correlation between the severity of inflammatory pouch disorders and the severity of joint, skin, and eye diseases are lacking. LIMITATIONS: This is a qualitative, not quantitative, review of case series and case reports. CONCLUSIONS: Primary sclerosing cholangitis and extraintestinal manifestations of the joints, skin, and eyes appear to be associated with inflammatory disorders of the ileal pouch. Although the treatment of pouchitis does not seem to affect the disease course of primary sclerosing cholangitis, effective therapy of inflammatory pouch disorders, particularly with biologics, likely benefits concurrent disorders of the joints, skin, and eyes.

Ocular Involvement in Graft-versus-Host Disease. / Augenbeteiligung bei Graft-versus-Host-Erkrankung.

In ocular graft-versus-host disease (GVHD), an inflammatory reaction occurs at the ocular surface after transplantation of allogeneic hematopoietic stem cells. Self-reactive T cells of the donor are particularly responsible for this. This can lead to a pronounced wetting disorder of the ocular surface, conjunctival hyperemia, and corneal ulceration up to perforation. The ocular GVHD is associated with a high degree of suffering, such as pain, photophobia, and reduction in visual acuity. This review provides an overview of typical ophthalmological findings, topical and systemic therapeutic approaches, and concomitant measures (e.g., scleral lenses, punctum plugs) and the appropriate management of complications.
