Summary
Human intraocular filariasis cases are rare, with few confirmed identifications. Many reported cases lack sufficient evidence, highlighting the need for detailed morphological descriptions for accurate diagnosis of eye worms.
Area of Science:
- Ophthalmology
- Parasitology
- Medical Entomology
Background:
- Intraocular filariasis, caused by parasitic worms in the eye, is a rare condition.
- Accurate identification of the causative filarial species is crucial for diagnosis and treatment.
Purpose of the Study:
- To review and analyze reported cases of human intraocular filariasis.
- To assess the reliability of case reports based on the quality of evidence provided.
Main Methods:
- Systematic review of 56 reported cases of intraocular filariasis.
- Evaluation of case details, including observation of worms, removal, description, and species identification.
Main Results:
- Only a small fraction of reported cases involved confirmed filarial presence with adequate description and identification.
- Identified species included Dipetalonema spp., Wuchereria, Dirofilaria, Loa loa, and Wuchereria bancrofti.
- Many cases were questionable due to lack of morphological description, artifactual findings, or non-filarial organisms.
Conclusions:
- A significant number of intraocular filariasis reports lack sufficient evidence for definitive diagnosis.
- Morphological description and identification are essential for validating cases of intraocular filariasis.

01:31Types of Intermediate Filaments
The intermediate filaments are an essential component of the cytoskeleton. Presently six types of intermediate filament have been identified. Type I and II are acidic and basic keratin proteins. Type III is of mesodermal origin and comprises four proteins: vimentin, desmin, glial fibrillary acidic protein (GFAP), and peripherin. Vimentin is commonly found in mesenchymal cells, desmin in muscle cells, GFAP in astrocytes, while peripherin is found in peripheral nervous system neurons (PNS). Type...
01:28Fungal Phylum Microsporidia
Microsporidia are a group of obligate intracellular fungi that were initially classified as protists but were later reclassified based on phylogenetic, molecular, and structural evidence linking them to the Chytridiomycota. These unicellular, non-motile organisms are highly specialized parasites that infect a wide range of animal hosts, including humans. They have evolved extensive genomic and metabolic reductions, making them highly dependent on their hosts for survival.Morphology and Genomic...
01:30Leishmaniasis
Leishmaniasis is a protozoal disease caused by species of the genus Leishmania and transmitted through the bite of infected female sandflies. The parasite exists in two principal morphological forms during its life cycle. A sandfly acquires intracellular amastigotes from an infected reservoir host, such as a dog. Within the sandfly, these forms differentiate into motile, flagellated promastigotes. During a subsequent blood meal, promastigotes are injected into the human host, where they...
01:28Toxoplasmosis
Toxoplasmosis, a zoonotic disease caused by the protozoan Toxoplasma gondii, poses significant public health challenges globally due to its high seroprevalence and varied clinical manifestations. As an obligate intracellular parasite, T. gondii can infect all warm-blooded vertebrates, but felids are its only definitive hosts, shedding unsporulated oocysts into the environment. Humans typically acquire the infection through ingestion of tissue cysts in undercooked meat or oocysts from...
01:22American Trypanosomiasis
Chagas disease, or American trypanosomiasis, is a vector-borne parasitic infection caused by Trypanosoma cruzi, a flagellated protozoan (kinetoplastid) of the family Trypanosomatidae. The disease is endemic in Latin America, although cases are increasingly reported worldwide due to human migration. Transmission most commonly occurs when feces of infected triatomine bugs contaminate bite wounds or mucosal surfaces; additional routes include congenital, transfusional, transplant-related, and oral...
01:15Anthelminthic Agents
Anthelmintic drugs differ significantly from antiparasitic therapies targeting protozoa, primarily due to differences in parasite biology. Whereas most protozoal treatments act on proliferating cells, anthelmintics are typically directed against mature, nonproliferative helminths. The therapeutic approach considers the helminth's reliance on neuromuscular coordination, glucose metabolism, and microtubular integrity for survival, reproduction, and localization within the host. Most anthelmintics...
