Subtenons infection by dirofilaria repens

Abstract

Zoonotic filariasis caused by Dirofilaria repens, a parasite of carnivores occurs mainly in countries surrounding Mediterranean region. The infection occurs in and around eye among animal handlers through vector transmission. We are reporting a case of human Dirofilariasis affecting subtenons region in a 63 year-old woman from Coimbatore, South India. The purpose of this article is to review the clinical course and management of ocular Dirofilariasis.

Intramuscular Gravid Dirofilaria repens Infection in Human - An Unusual Presentation

“…These features are absent in D.immitis. [9]In the neighboring Trissur district of Kerala, microfilariae of D. repens have been reported in 7% of domestic dogs. Hence an enhanced rate of infection can be anticipated among stray dogs.…”

Subconjunctival Infection due to Dirofilaria Repens ‐Case Report

“…In addition, a few episodes of disease exacerbation can occur until the definite diagnosis is made. In the described cases of the deep periocular localization, patients had nonspecific and even unusual symptoms, and were exposed to the harmful effects of various diagnostic procedures (7,9,12,26). In case of human ocular dirofilariosis, the subconjunctival or subtenonic type, the localization allows easy and quick diagnosis of the parasite infection, since the conjunctiva is transparent and the parasite can be directly visible (27)(28)(29).…”

“…In case of parasites migration to the deeper parts of the orbit, diagnosis is made by excisional biopsy, which also leads to complete cure; however, the surgery is very complicated (12).…”

Ocular Dirofilariasis: A Rare case from Mumbai, India

“…The cephalic space is a criterion used routinely for the easy differentiation of these microfilariae and identification of the species. Also, morphologically longitudinal cuticular ridges are absent in D. immitis whereas are present in D. repens [9]. Infection can be prevented by avoiding mosquito bites in endemic areas for dirofilariasis.…”
