Ocular cysticercosis: an epidemiological study

Abstract

The objetive of the research was to verify the incidence of the ocular form of cysticercosis among the patients who consulted professionals of the field, during the first statistic inventory accomplished in the State of Paraná, Brazil. The 1996 research was performed through a questionnaire sent to all 220 members of Paraná Ophthalmology Association and to the 17 members of Pathology and Cytology Department of the Paraná Medical Association. A pre-stamped envelop for the return of the answers was included in the package. We received 99 answers from ophthalmologists and 10 answers from pathologists. Retrospective and epidemiological research about the incidences of the ocular cysticercosis in the State of Paraná, added to national related published reports, rendered 95 cases probably adquired in Paraná, 71 of the cases were referred in this research and 24 in prior publication. The most frequent localization was vitreous and subretinal, as literature had already pointed out.KEY WORDS: ocular cysticercosis, Paraná State Brazil, incidence.Cisticercose ocular: um estudo epidemiológico RESUMO O objetivo da pesquisa foi o de verificar a incidência da forma ocular de cisticercose entre os pacientes que consultam profissionais da área, no primeiro levantamento estatístico realizado no Estado do Paraná. A pesquisa retrospectiva e epidemiológica foi realizada em 1996 através de encaminhamento por correio, de um questionário com envelope com porte pago para resposta aos 220 membros da Associação Paranaense de Oftalmologia e aos 17 membros do Departamento de Patologia e Citologia da Associação Médica do Paraná, dos quais obtivemos 99 cartas-respostas dos oftalmologistas e 10 dos patologistas. A pesquisa retrospectiva, associada aos relatos de outros casos já referidos na literatura nacional, permitiu-nos reunir 95 casos de cisticercose ocular, provavelmente adquiridos no Paraná, sendo 71 casos referidos nesta pesquisa e 24 em publicação anterior. A localização ocular mais frequente foi a vítrea e subretiniana, fato já salientado na literatura. PALAVRAS-CHAVE: cisticercose ocular, Estado do Paraná, incidência.

Submacular Cysticercosis Successfully Treated through Conservative Management: Case Report

“…The cysticercus can affect any of the ocular structures, and frequency and type of symptoms depend on the location of the cysts. Although there are reports that describe the subconjunctival location as the most frequent, extensive epidemiological studies have shown that the intravitreal and subretinal locations are much more common than the involvement of the anterior segment and the eye annexes [4,7].…”

Extraocular muscle cysticercosis mimicking idiopathic orbital inflammation: case report

“…Cysticercosis usually affects highly vascularized tissues such as the brain, the mastigatory muscles, the tongue and the heart. It is caused by Cysticercus cellulosae, in a resting stage of the Taenia solium larvae in the intermediate host (4) and infects the orbit and adnexa at 5 to 8.4% of all ophthalmic cases (5)(6) . It is most commonly found in the extraocular muscles (7) leading to restricted eye movements and inflammatory signs (4) as exemplified by our case in which the superior rectus was affected leading to marked hypertropia and limitation of infraduction.…”

A comprehensive review of imaging findings in human cysticercosis

“…Multiple cysts may occur in the same eye. The most common location of ocular cysticercosis varies from one region to another [54]. …”
