ImportanceOphthalmic 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.ObjectiveTo present a case of human mpox with sight-threatening necrotizing blepharoconjunctivitis.Design, Setting, and ParticipantsThis 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 MeasuresDescription of the progression and clinical evaluation of the ocular condition and the management.ResultsA 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 RelevanceThe 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.
Introduction Ocular surface squamous neoplasia (OSSN) and pterygia share risk factors and co-exist in only a minority of cases. Reported rates of OSSN in specimens sent as pterygium for histopathological analysis vary between 0% and nearly 10%, with the highest rates reported in countries with high levels of ultraviolet light exposure. As there is a paucity of data in European populations, the aim of this study was to report the prevalence of co-existent OSSN or other neoplastic disease in clinically suspected pterygium specimens sent to a specialist ophthalmic pathology service in London, United Kingdom. Methods We performed a retrospective review of sequential histopathology records of patients with excised tissue submitted as suspected “pterygium” between 1997 and 2021. Results In total, 2061 specimens of pterygia were received during the 24-year period, with a prevalence of neoplasia in those specimens of 0.6% (n = 12). On detailed review of the medical records of these patients, half (n = 6) had the pre-operative clinical suspicion of possible OSSN. Of those cases without clinical suspicion pre-operatively, one was diagnosed with invasive squamous cell carcinoma of the conjunctiva. Conclusion In this study, rates of unexpected diagnoses are reassuringly low. These results may challenge accepted dogma, and influence future guidance for the indications for submitting non-suspicious pterygia for histopathological analysis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
