Thelazia rhodesii was found in the eyes of 149 of 643 bovine heads (23%) that were examined at the abattoir of Cagayan de Oro City, Philippines, during the period February 1994 to February 1995. In nearly half of the animals both eyes were infected and an average of 4.1 worms per infected animal was recovered. Of the 1286 eyes examined, 17% were infected; worm burdens ranged from one to 36 (average 2.9) worms per infected eye. Monthly prevalence of infection ranged from 13% to 36%. T. rhodesii infection was significantly more common in cattle of more than 3 years of age (25%) than in younger animals (15%). Ocular lesions were observed in 73 (11%) cattle; 22% of these were infected with T. rhodesii. There was no relationship between presence of T. rhodesii and ocular lesions.
1994年2月至1995年2月期间，在菲律宾卡加延德奥罗市的屠宰场对643头牛的头部进行检查，发现其中149头（23%）的眼睛中有罗得西亚吸吮线虫。近半数动物的双眼均受感染，每头受感染动物平均检获4.1条虫。在检查的1286只眼睛中，17%受到感染；每只受感染眼睛的虫负荷量为1至36条（平均2.9条）。每月的感染率在13%至36%之间。罗得西亚吸吮线虫感染在3岁以上的牛（25%）中比年幼动物（15%）中更为常见。在73头（11%）牛中观察到眼部病变；其中22%感染了罗得西亚吸吮线虫。罗得西亚吸吮线虫的存在与眼部病变之间没有关联。
