Tumor-like lymphoplasmacytic conjunctivitis in the third eyelid in a dog.

This report aims to describe a case of tumor-like lymphoplasmacytic conjunctivitis in a 7-year-old spayed-female Pomeranian. On complete ophthalmic examination, a mass with papillary projections was noted on the bulbar surface of the right third eyelid. Debulking of the mass was performed while preserving as much of the third eyelid as possible. On the histopathological examination, the mass was diagnosed as lymphoplasmacytic conjunctivitis with mild epithelial hyperplasia. Although a slight regrowth of the mass was noted 3 weeks after surgery, intralesional injection of triamcinolone acetonide led to its disappearance. There was no further recurrence after 5 months.

Natural history of adenoviral conjunctivitis in a US-based population: Viral load, signs, and symptoms.

PURPOSE: To report the clinical signs, symptoms, and viral clearance in individuals in the United States with adenoviral conjunctivitis (Ad-Cs). METHODS: Individuals ≥ 18 years presenting within 4 days of symptoms of Ad-Cs who met eligibility criteria and tested positive with both point-of-care immunoassay antigen and quantitative polymerase chain reaction (qPCR) testing were enrolled. Patient-reported symptoms, clinician-graded signs, and qPCR viral titers were collected at baseline, days 1-2, 4 (days 3-5), 7 (days 6-10), 14 (days 11-17) and 21 (days 18-21). RESULTS: There was no detectable viral titers by the day 14 visit in 6/8 patients. By day 21, there was no detectable viral titers in the 7 participants who completed the visit; however, signs and symptoms persisted including: blurry vision (5/7), discomfort (2/7) or redness (1/7). Masked clinicians also noted conjunctival redness (4/7), follicular conjunctivitis (4/7) and bulbar edema (3/7). CONCLUSION: Many patient-reported symptoms and clinical signs persist after viral titers are no longer detectable by qPCR. Using clinical signs and symptoms to determine quarantine duration may result in patients being furloughed longer than the time that the patient is infectious.

Afectación ocular secundaria a la infección por Monkeypox virus / Ocular involvement secondary to Monkeypox virus infection

Presentamos el caso de un paciente varón de 37años con cuadro compatible con conjuntivitis adenovírica de 5días de evolución. Se pautaron corticoides tópicos, lubricantes y retirada de pseudomembranas. El análisis mediante PCR del exudado conjuntival resultó positivo para Monkeypox virus. Durante el seguimiento presentó úlceras corneales de evolución tórpida, por lo que precisó ingreso para instaurar tratamiento con tecovirimat. La afectación ocular por Monkeypox virus suele ser leve y autolimitada. Se han descrito casos con afectación visual severa cuando hay daño corneal, tal y como se ejemplifica en este caso. Tras el ingreso hospitalario para tratamiento sistémico, presentó una evolución favorable. (AU)

We present the case of a 37-year-old male patient with symptoms compatible with adenoviral conjunctivitis of 5days’ evolution. Topical corticosteroids, lubricants and removal of pseudomembranes were prescribed. PCR analysis of conjunctival exudate was positive for Monkeypox virus. During follow-up, the patient developed corneal ulcers with a torpid course, requiring admission for treatment with tecovirimat. Ocular involvement by Monkeypox virus is usually mild and self-limiting. Cases with severe visual involvement have been described when there is corneal damage, as exemplified in this case. After admission to hospital for systemic treatment, the patient progressed favourably. (AU)

Isolated corneal involvement by Lichen Planus - multi-modal evaluation.

PURPOSE: To describe a case of ocular Lichen Planus, successfully managed using a multimodal evaulation, including Anterior Segment OCT (AS-OCT). OBSERVATIONS: A female patient in her forties with a history of cutaneous Lichen Planus presents with blurred vision and burning eye sensation. Anterior segment evaluation revealed bilateral punctate keratitis, stromal haze and subepithelial pigmented dots. AS-OCT was pivotal for diagnosis, showing anterior stromal hyperreflective dots. A diagnosis of ocular Lichen Planus was estabilished and the patient was treated with topical hydrocortisone, with complete subsidence of the complaints. CONCLUSIONS AND IMPORTANCE: Ocular Lichen Planus can present as isolated corneal involvement independent from severe cicatrizing conjunctivitis. Appropriate and timely treatment can prevent irreversible ocular surface disease. Ophthalmologists should be aware of Lichenoid Tissue Reaction (LTR) disorders, especially in patients with relentless blepharitis and/or ocular surface disease.

Ocular involvement secondary to Monkeypox virus infection.

We present the case of a 37-year-old male patient with symptoms compatible with adenoviral conjunctivitis of 5 days' evolution. Topical corticosteroids, lubricants and removal of pseudomembranes were prescribed. PCR analysis of conjunctival exudate was positive for Monkeypox virus. During follow-up, the patient developed corneal ulcers with a torpid course, requiring admission for treatment with Tecovirimat. Ocular involvement by Monkeypox virus is usually mild and self-limiting. Cases with severe visual involvement have been described when there is corneal damage, as exemplified in this case. After admission to hospital for systemic treatment, the patient progressed favourably.

Clinical features of 26 cases of COVID-19-associated conjunctivitis.

PURPOSE: To explore the clinical features of COVID-19-associated conjunctivitis with the objective of preventing the spread of infection. STUDY DESIGN: Retrospective cohort study. METHODS: From March 2020 to March 2021, we retrospectively reviewed 26 (9.8%) consecutive COVID-19 patients with conjunctivitis among 282 COVID-19 cases admitted to our hospital. Clinical symptoms, onset date of conjunctivitis, time to patient recovery, and eye drop intervention were investigated. In addition, risk factors for developing conjunctivitis were statistically examined among 206 inpatients available for within 5 days of the onset. A multivariate analysis of conjunctivitis risk factors was performed. RESULTS: Among the 282 COVID-19 patients, 4 (1.4%) had conjunctival hyperemia as the primary symptom. The median time of onset was 4 days after the COVID-19 onset. Hyperemia was observed in all cases, but other ocular symptoms were rare. The median duration of hyperemia was 3 days. A multiple logistic regression analysis revealed that a young age (p=0.005) and current smoking habit (p=0.027) were independent risk factors for conjunctivitis after COVID-19. CONCLUSIONS: COVID-19-associated conjunctivitis is rare in the elderly and strongly associated with a history of smoking. It often occurs in the early stages of infection, and while hyperemia is recognized as a clinical symptom, other ocular symptoms are rare or non-existent. Many cases recover within a short time.

Diagnosis of Immunoglobulin G4-related disease in a child with ligneous conjunctivitis: a novel mutation in plasminogen gene and plasminogen activator inhibitor-1 polymorphism.

OBJECTIVES: Ligneous conjunctivitis (LC) is a chronic conjunctivitis characterized by recurrent, firm, fibrin-rich, woody pseudomembranes on the palpebral conjunctiva. It is an ultrarare autosomal recessive disease associated with congenital plasminogen (PLG) deficiency due to mutations in the PLG gene (6q26). Immunoglobulin G4-related disease (IgG4-RD) is an idiopathic, systemic fibroinflammatory disease characterized by elevated serum IgG4 concentration and tissue infiltration of IgG4-positive plasma cells leading to organ enlargement, fibrosis and damage. CASE REPORT: A 7-year-old girl with LC was hospitalized for recurrent pancreatitis and diagnosed as IgG4-RD. PLG activity level was 15% (normal range 55-145%). Co-segregation analysis indicated that the patient was homozygous for the c. NG_016200.1(NM_000301.5):c.1465 T>C mutation in PLG gene. c. NG_016200.1(NM_000301.5):c.1465 T>C PLG variant was found to be heterozygous by NGS analysis in both parents. She also had plasminogen activator inhibitor - 1 (PAI-1) NG_013213.1(NM_000602.5):c.-816A>G (4G/4G) homozygous polymorphism and a heterozygote NG_001333.2 (NM_002769.5):c.292_293insC mutation in the serine protease 1 (PRSS-1) gene. However, heterozygous PRSS-1NG_001333.2 (NM_002769.5):c.292_293insC variant was found in the mother of the patient. All detected variants are currently considered as a variant of uncertain (or unknown) significance (VUS) according to the American College of Medical Genetics and Genomics (ACMG) classification. Oral steroid, oral azathioprine, topical fresh frozen plasma, topical heparin, topical steroid and topical cyclosporine were given. After 3 years of follow-up, IgG4-RD is under partial remission and no pseudomembranes. CONCLUSION: She is the second case had both LC and IgG4-RD. We identified a NG_016200.1(NM_000301.5):c.1465 T>C novel homozygous mutation in PLG gene and a PAI-1 NG_016200.1(NM_000301.5):c.1465 T>C (4G/4G) homozygous polymorphism, which has been reported as a risk factor for thrombotic events.

A case of lipogranulomatous conjunctivitis in a horse.

OBJECTIVE: To describe a case of lipogranulomatous conjunctivitis in a horse. ANIMAL STUDIED: A client-owned 12-year-old Standardbred gelding presenting with chronic conjunctivitis and palpebral masses. METHODS: Complete ophthalmic examination, surgical excision, histopathology, and bacterial culture of biopsy samples were performed. RESULTS: Upper and lower eyelids of both eyes were affected, with multiple yellow-to-white nodules on the palpebral conjunctiva, adjacent to the eyelid margin. Nodule removal was achieved via partial tarsal plate excision. Histopathological examination revealed granulomatous inflammation and large droplets of presumed free lipid in the conjunctival lamina propria. The animal was diagnosed with lipogranulomatous conjunctivitis. No postoperative ocular discomfort was observed for months; however, 3 years later, new conjunctival nodules were noticed, requiring a second surgical procedure on three of the eyelids. Transient entropion in the left lower eyelid was observed 2 months after the second surgery, and no recurrence of conjunctival nodules was observed after 18 months of follow-up. CONCLUSION: To our knowledge, this is the first report of lipogranulomatous conjunctivitis in horses.

A case of IgG4-positive ligneous conjunctivitis mistaken for a conjunctival mass.

BACKGROUND: Ligneous conjunctivitis (LC) is a rare inflammatory lesion of the conjunctiva with an unknown etiology. It is easily confused with conjunctiva lymphoma or other diseases in clinical diagnosis, and the lesion is very difficult to treat. CASE PRESENTATION: We presented a 41-year-old female patient presented with bilateral conjunctival masses for more than six months. The patient had no contributory history of ocular trauma, family history of tumor and drug allergy. Taking the patient's clinical and pathological features together, we considered this was a case of IgG4 + LC. Completely surgical resection combined with local glucocorticoid treatment might be effective. CONCLUSIONS: This is a very rare case report of immunoglobulin G4 positive LC with only one published case in literature. The typical manifestations of LC are with the appearance of a hard, fibrin-rich, woody pseudomembranous lesion. A large number of lymphocyte and plasma cell are infiltrated in the pathological tissue. Inflammation of LC may cause immune abnormalities, resulting in IgG4 increasing.

Meningococcal Conjunctivitis in a 54-Year-Old Man: Case Report and Review of the Literature.

Neisseria meningitidis represents an uncommon pathogen of acute bacterial conjunctivitis. In this brief report, we describe a case of meningococcal conjunctivitis in an immunocompetent adult male, with a review of the literature. The patient went to the outpatient ophthalmology clinic complaining of severe ocular discomfort, burning, and redness for more than 2 weeks and, at slit lamp examination, he was diagnosed with a mild conjunctivitis. Microbiology cultures of ocular swabs revealed the growth of colonies, as pure culture, identified as N. meningitidis of serogroup B. A diagnosis of primary meningococcal conjunctivitis was made and treatment of patient with intramuscular injections of ceftriaxone in addition to topical moxifloxacin eye drops for 2 weeks led to clinical improvement and, finally, to a complete recovery, in accordance with microbiological findings. Ophthalmologists must be aware of the possibility of primary meningococcal conjunctivitis cases, even uncommon, and the need to treat with systemic antibiotics and their close contacts with adequate antibiotic chemoprophylaxis.

A prospective long-term evaluation of the ocular findings of children followed with the diagnosis of multisystem inflammatory syndrome (long-term evaluation of ocular findings following MIS-C).

BACKGROUND/OBJECTIVES: The most frequently reported ocular finding in the acute phase of the multisystem inflammatory syndrome in children (MIS-C), is conjunctivitis. More rarely, punctuate epitheliopathy, anterior uveitis and optic disc oedema can be seen. We aimed to investigate the acute and long-term ocular effects of MIS-C. SUBJECTS/METHODS: Cases aged 1 month to 18 years who were diagnosed with MIS-C between January 2022 and June 2022 in the Department of Pediatric Infectious Diseases in our hospital were included in the study. Ophthalmological examinations were performed immediately after diagnosis, at one month, three months, and six months. RESULTS: Males consisted of 64.7% of the 34 cases included in the study and the mean age was 8.68 ± 4.32 years (min-max:2-17). In the first examination, conjunctivitis was observed in 6 (17.6%), punctuate epitheliopathy in 4 (11.7%), and subconjunctival haemorrhage in 3 (8.8%) patients. Two patients (5.8%) had optic disc oedema. No pathological anterior or posterior segment findings were observed in the sixth-month examination. The relationship between subconjunctival haemorrhage and intensive care hospitalisation was statistically significant (p = 0.014). Also, all patients with subconjunctival haemorrhage were clinically classified as severe MIS-C (p = 0.002). CONCLUSION: Although pathological ocular findings were observed in the acute phase of the disease, all of them were found to be improved at the sixth-month follow-up. The most striking finding of our study is that cases with subconjunctival haemorrhage were clinically more severe, and all patients needed intensive care. This study may be informative in establishing ocular follow-up protocols that are expected to be carried out in the acute period and in the follow-up of these patients.

A closed-loop audit of the prescription practice of topical antibiotics for acute infective conjunctivitis.

Objective: The implementation of guideline recommendations for antibiotics prescription for the management of patients with acute infective conjunctivitis (AIC) in primary care departments remains below par. Our objective was to assess the impact of clinical audit on adherence to evidence-based indications for prescription of antibiotic eye drops in patients diagnosed with AIC, in the setting of a primary care practice in western Greece. Methods: We conducted a retrospective audit to evaluate the current prescription practice of antibiotics for the management of AIC. Following evidence-based indications for the prescription of antibiotics in AIC through literature search, and in combination with discussion and collaboration with the primary care doctors of our department, we formulated and implemented guidelines for the management of AIC. We then performed a prospective re-audit to assess the management of patients with AIC after local implementation of the guidelines. Results: A total of 158 cases were audited in the first cycle before the introduction of the guidelines, from 15th June 2019 to 7th March 2020, and 26 cases after, from 10th March 2020 to 20th November 2020. The compliance with the guidelines regarding antibiotics prescription was significantly improved from 12.0% to 84.6% between the first and the second cycles of audit. Conclusions: In this study, with the local introduction of guidelines, clinical audit significantly improved the prescription practice of topical antibiotics in patients with AIC in a primary care department. Abbreviations: AIC = acute infective conjunctivitis.

Necrotizing Blepharoconjunctivitis and Keratitis in Human Monkeypox.

Importance: Ophthalmic manifestations occur in less than 5% of patients with human mpox (monkeypox), most commonly presenting with self-limiting conjunctivitis and keratitis. Cases with severe ophthalmic complication are uncommon. Objective: To present a case of human mpox with sight-threatening necrotizing blepharoconjunctivitis. Design, Setting, and Participants: This is a report of a patient who developed necrotizing conjunctivitis due to the monkepox virus at a large university hospital. Data were collected from July to October 2022. Main Outcomes and Measures: Description of the progression and clinical evaluation of the ocular condition and the management. Results: A 63-year-old HIV-positive man presented initially with conjunctivitis and eyelid swelling and developed skin lesions from monkeypox virus 2 days later. Despite remaining stable systemically, after 4 days, his ophthalmic condition evolved to necrotizing blepharoconjunctivitis for which systemic antiviral treatment with tecovirimat was given along with topical trifluoridine, 1%, eye drops. In addition, he required repeated tissue debridement with amniotic membrane grafting to preserve the eye integrity. Conclusions and Relevance: The severity of this observation was associated with a coexisting immunocompromised state and appeared similar to findings associated with other orthopoxviruses. Ophthalmic manifestations could be the initial presentation of human mpox and could also be severe. Early recognition and intervention may limit the likelihood of substantial ocular morbidity.
