We report a case of intraocular gnathostomiasis diagnosed by western blot assay in a patient with subretinal tracks. A 15-year-old male patient complained of blurred vision in the right eye, lasting for 2 weeks. Eight months earlier, he had traveled to Vietnam for 1 week and ate raw wild boar meat and lobster. His best-corrected visual acuity was 20/20 in both eyes and anterior chamber examination revealed no abnormalities. Fundus examination showed subretinal tracks in the right eye. Fluorescein angiography and indocyanine green angiography showed linear hyperfluorescence of the subretinal lesion observed on fundus in the right eye. Ultrasound examination revealed no abnormalities. Blood tests indicated mild eosinophilia (7.5%), and there was no abnormality found by systemic examinations. Two years later, the patient visited our department again for ophthalmologic evaluation. Visual acuity remained 20/20 in both eyes and the subretinal tracks in the right eye had not changed since the previous examination. Serologic examination was performed to provide a more accurate diagnosis, and the patient's serum reacted strongly to the Gnathostoma nipponicum antigen by western blot assay, which led to a diagnosis of intraocular gnathostomiasis. This is the first reported case of intraocular gnathostomiasis with subretinal tracks confirmed serologically using western blot in Korea.

Resumo: A gnatostomíase é parasitose endêmica em alguns países asiáticos, causada pela ingestão da larva do nematódio Gnathostoma sp, que pode ocorrer no consumo de carne crua de peixes de água doce. Atinge vários órgãos, entre eles a pele, manifestando-se frequentemente como lesão subcutânea migratória. Países da América Central e do Sul como México e Peru vêm apresentando número crescente de casos da doença desde 1970. Este trabalho registra o primeiro caso notificado e publicado no Brasil e alerta para o surgimento dessa doença em áreas anteriormente não endêmicas. Relata-se caso de paciente, com história de viagem ao Peru, que evoluiu com quadro cutâneo compatível com gnatostomíase. Palavras-chave: Gnathostoma; Helmintos; Paniculite Abstract: Gnathostomiasis is an endemic disease in Asian countries caused by the ingestion of larval stage of Gnathostoma sp roundworms that may be acquired by eating raw fresh-water fish. It can reach many organs and the skin is one of them, characterized by creeping eruptions and/or migrating erythema. Since 1970 the number of patients affected seems to be increasing in Central and South America countries like Mexico and Peru. This is the first notification and publication of gnathostomiasis in Brazil, and it serves as an alert to the possibility of the emergence of this disease in non-endemic areas. We report a case of a man who traveled to Peru and developed cutaneous features accordant with gnathostomiasis.

“…Palpebral oedema with conjuctival erythema developed when lesions developed near the eye. Intraocular parasites occur so rarely that they are considered as ophthalmological curiosities, nevertheless, it can cause intraocular hemorrhage, uveitis, and loss of vision within 2 days [53]. Following surgical removal, treatment is with albendazole and topical corticosteroids.…”

Ocular parasitosis in human is more prevalent in geographical areas where environmental factors and poor sanitary conditions favor the parasitism between man and animals. Lesions in the eye can be due to damage directly caused by the infectious pathogen, indirect pathology caused by toxic products, or the immune response incited by infections or ectopic parasitism. The epidemiology of parasitic ocular diseases reflects the habitat of the causative parasites as well as the habits and health status of the patient. An ocular examination may provide clues to the underlying disease/infection, and an awareness of the possibilities of travel-related pathology may shed light on an ocular presentation. This paper is a comprehensive review of the parasitic diseases of the eye. The majority of the clinically important species of parasites involved in eye infection are reviewed in this paper. Parasites are discussed by the disease or infection they cause.
