The First Genetically Confirmed Case of Human Ophthalmomyasis Due to Oestrus ovis (Diptera Oestridae) in Bosnia and Herzegovina

Purpose Here we present a case of human ophthalmomyasis due to Oestrus ovis in a patient living in an urban area. Dipterians of the Ostridae family may occasionally deposit larvae into the human eye and cause ocular parasitosis called ophthalmomyasis. Cases like this are mostly connected with people who live in close contact with animals, like shepherds, but are rarely presented in urban population. Methods The patient was presented at University Clinic due to problems with his left eye, that persist no matter on treatment in local clinic a few days before. During the slit lamp examination larvae was detected and extracted from the conjunctiva. Genomic DNA was isolated from the sample and genetic analysis was performed. Results Larvae was identified as a first-stage larvae of O. ovis . Conclusion This is the first report of genetically confirmed case of ophthalmomyasis in Bosnia and Herzegovina. In cases like this, clinicians should be aware of possibility of this rarely described presentation of ocular parasitosis since even the urban population can be accidentally affected due to a lack of natural hosts.
