Case Report: Zoonotic Ocular Thelaziosis Infection in Two Dogs and Treatment

Abstract

A 1.5-year-old female, hunting dog and a 6-year-old male crossbred dog presenting with eye discharge, conjunctival hyperemia and swelling were reported in this study.After a local anesthetic drug was administered, oph-thalmological examination revealed a variable degree of ocular discharge, blepharospasm, conjunctival hyperemia, and the presence of movable parasites hidden behind the third eyelid membrane. A total of 15 parasites (5 males, 10 fe-males) were removed from the eyes of both cases. All the parasites were submitted to the department of parasitology for morphological identification. According to ocular and parasitological examination findings, thepatients were diag-nosed with ocular thelaziasis. For treatment, a single time 10% imidacloprid and 2.5% moxidectin spot on (Advocate®, Bayer, Slovakia) was applied and tobramycine-dexamethasone (Tobradex®, Alcon, Turkey) 3 times a day, fusidic acid (Fucithalmic®, Abdi Ibrahim, Turkey) twice a day were usedtopically for 2 weeks. Mechanical removal of parasites and medical treatment were positive in both patients.

İki Köpekte Zoonotik Oküler Thelaziosis İnfeksiyonu ve Tedavisi

Abstract

Bu çalışmada göz akıntısı, konjonktival hiperemi ve şişlik şikayetleri ile başvuran 1.5 yaşında dişi bir av köpeği ile 6 yaşında erkek melez bir kopek bildirilmiştir. Lokal anestezik uygulama sonrası, yapılan oftalmolojik muayenede değişen derecede oküler akıntı, blefarospazm, konjunktival hiperemi ve üçüncü göz kapağı zarının arkasına gizlenmiş hareketli parazitlerin varlığı tespitedildi. Her iki olgunun gözlerinden toplam 15 parazit (5 erkek, 10 dişi) uzaklaştırıldı. Morfolojik tespit için tüm parazitler parazitoloji bölümüne gönderildi. Oküler ve parazitolojik muayene bulgularına göre, hastalara oküler thelaziasis teşhisi konuldu. Tedavide tek uygulama olarak %10 imidakloprid ve%2.5 moksidektin spot-on (Advocate®, Bayer, Slovakya) uygulandı ve tobramisin-deksametazon (Tobradex®, Alcon, Türkiye) günde 3 kez, fusidikasit (Fucithalmic®, Abdi Ibrahim, Türkiye) 2 hafta boyuncag ünde 2 kez topical olarak kullanıldı. Parazitlerin me-kanik olarak uzaklaştırılması ve medical tedavi her iki hastada olumlu sonuçlandı.
