RESUMEN
Thelazia callipaeda (Nematoda: Spirurida: Thelaziidae) parasitizes the eyes of dogs, cats, humans, and various wild mammals, and is transmitted by drosophilid flies. In Japan, T. callipaeda is considered an emerging parasite that has expanded its endemic region northward. However, reports of its detection in mammals other than domestic animals and humans are scarce. This study reports the detection of T. callipaeda in Japanese red fox (Vulpes vulpes japonica), masked palm civet (Paguma larvata), Japanese badger (Meles anakuma), Japanese black bear (Ursus thibetanus japonicus), raccoon (Procyon lotor), Japanese raccoon dog (Nyctereutes viverrinus), domestic dog (Canis lupus familiaris), domestic cat (Felis silvestris catus), and human. Of these, the Japanese red fox, masked palm civet, Japanese badger, and Japanese black bear have been reported as novel host records. Sequence analysis of the cytochrome c oxidase subunit I gene of T. callipaeda revealed two unique lineages specific to Japan, with no regional or host species differences. These results suggest a wide host range for T. callipaeda, highlighting the significant role of wildlife as a reservoir for this parasite in Japan.

We report a case of persistent traumatic cyclodialysis treated by goniophotocoagulation and observed by ultrasound biomicroscopy (UBM) throughout the course. A 16 year-old male was struck in his right eye by a rocket firework. After the injury, hypotony continued for 4 months and he was referred to Hiroshima University Hospital. At that time, the best visual acuity in his right eye was 0.2 and the intraocular pressure was 6 mmHg. Three hundred and sixty degrees of cyclodialysis, partial peripheral anterior synechia, hypotony maculopathy and subretinal proliferative tissue were observed. Cyclodialysis was obvious by UBM. From 4 months after the injury goniophotocoagulation was performed six times in 2 months. Intraocular pressure recovered 6 months after the injury and reattachment of cyclodialysis and disappearance of the suprachoroidal space were confirmed by UBM. UBM was useful in observing cyclodialysis throughout the course.
