Ocular parasitosis caused by protozoan infection during travel: Focus on prevention and treatment

et al. 2018

International travel is rising quickly worldwide. Many people travel to tropical and subtropical areas, where there has been increasing exposure of travelers to infectious pathogens. Ocular parasitic infections are more prevalent in these geographical areas and they can lead to morbidity and mortality, often due to late or misdiagnosis due to the unfamiliarity of health staff with these diseases. This is an up-to-date comprehensive review article that familiarizes physicians with ocular signs and symptoms, treatment, prevention, and geographic distribution of some parasites associated with travel.

“…Ocular damage can be caused directly by the infectious pathogen or indirectly by the toxic products, immune response incited by infections, or ectopic parasitism of the preadult or adult stages. 12,[19][20][21][22] Parasitic infections are sources of morbidity and mortality. 23 An Ophthalmologist, Stephen Mckenzie, identified microfilaria, in 1890.…”

Loa loa is a nematode that is highly endemic in the tropical rainforests of Western and Central Africa. It is also known as “African eye worm”. Occasionally the adult parasite is seen in the subcutaneous tissue space of humans and occasionally into the subconjunctival space. Our case is a 29-year-old male presented to the outpatient department with history of swelling, redness and foreign body sensation in the inferior bulbar conjunctiva of his right eye. Slit lamp examination shows, a nodular swelling in the inferior conjunctival space and diagnosed as subconjunctival granulomatous lesion. In the operation theater, the lesion was explored and a live worm was removed from the subconjunctival space. The worm was measured about 3.5 cm in length. The worm was confirmed to be a Loa loa adult specimen. The patient was treated with 400 mg oral albendazole for 3 weeks and 60 mg prednisone. Ophthalmologists should be aware of the typical manifestations and possible unusual presentations. An increasing number of subconjunctival Loa loa cases are reported from non-endemic areas are due to increased travel and migration. This report illustrates an unusual ocular disease, which is usually not found outside of Africa, but easily diagnosed and treated.

Water related ocular diseases

A number of ocular diseases can be attributed to contaminated water and we have coined a term "Water-related ocular diseases (WRODs)" to denote this wide-spectrum of conditions. WRODs are directly related to human contact with water and can occur through toxic, allergic, inflammatory or infective mechanisms. The non-infective causes can include chemicals used to clean swimming pools, oil spills and water-sport related injuries. Similarly, a number of infective organisms causing ocular diseases are transmitted through water. Since, these conditions can occasionally prove devastating, a review was done with the following aims: (i) To study the epidemiology of WRODs (ii) To assess the clinical presentation and current management of WRODs (iii) To highlight the future challenges and possible solutions to these problems. The online search was conducted utilizing search engines such as PubMed, Google Scholar, ClinicalKey and the Virtual Library of the Ministry of Health, Malaysia for relevant terms such as water-borne, swimming pool and eye infections.
