Accessory Structures of the Eye01:17

Accessory Structures of the Eye

Optical perception, or vision, is an extraordinary sense dependent on converting light signals received via the ocular organs. These organs, known as eyes, are securely positioned within the bony cavities of the skull, called orbits. The orbits serve a dual purpose: a protective shield for the ocular globes and a stable attachment point for the soft ocular tissues. The eye's external protective mechanisms include the eyelids, which are edged with lashes that act as a barrier against foreign...
Electron Orbital Model01:18

Electron Orbital Model

Orbitals are the areas outside of the atomic nucleus where electrons are most likely to reside. They are characterized by different energy levels, shapes, and three-dimensional orientations. The location of electrons is described most generally by a shell or principal energy level, then by a subshell within each shell, and finally, by individual orbitals found within the subshells.
The first shell is closest to the nucleus, and it has only one subshell with a single spherical orbital called the...
Circular Orbits and Critical Velocity for Satellites01:16

Circular Orbits and Critical Velocity for Satellites

The Moon orbits around the Earth. In turn, the Earth (and other planets) orbit the Sun. The space directly above our atmosphere is filled with artificial satellites in orbit. One can examine the circular orbit, the simplest kind of orbit, to understand the relationship between the speed and the period of planets and satellites with respect to their positions and the bodies that they orbit.
Nicolaus Copernicus (1473-1543) first suggested that the Earth and all other planets orbit the Sun in...
Anthelminthic Agents01:15

Anthelminthic 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...
Microbial Interactions: Parasitism01:22

Microbial Interactions: Parasitism

Parasitism is a form of microbial interaction in which parasitic microbes exploit a host organism for nutrients and shelter, often at the host's expense. Unlike mutualistic relationships, where both organisms benefit, parasitism benefits only the parasite and harms the host.Classification of ParasitesMicrobial parasites are broadly classified based on their location relative to the host.Ectoparasites remain on the host’s surface, such as the skin or outer tissues, drawing nutrients...
Microbiome of the Eye01:22

Microbiome of the Eye

The human eye has a specialized microbiota that reflects its unique anatomical and immunological environment. This low-biomass microbial community predominantly colonizes the conjunctiva and eyelid margins, playing a vital role in ocular surface homeostasis and defense. Despite its proximity to the richly colonized facial skin, the ocular surface maintains a distinct microbial profile due to continuous mechanical and biochemical defense mechanisms.The conjunctival surface hosts fewer microbial...

Area of Science:

  • Ophthalmology
  • Infectious Diseases
  • Parasitology

Background:

  • Orbital parasitoses are uncommon conditions affecting the eye socket.
  • The orbital space's unique anatomy can lead to varied presentations, often mimicking tumors or inflammatory conditions.
  • Accurate diagnosis and management are crucial due to potential vision impairment.

Purpose of the Study:

  • To review the clinical, epidemiological, and treatment aspects of orbital parasitic infections.
  • To consolidate worldwide data on orbital parasitoses for better understanding.
  • To aid clinicians in diagnosing and managing these rare diseases.

Main Methods:

  • Systematic literature review of orbital parasitoses.
  • Analysis of clinical manifestations, patient demographics, and geographical distribution.
  • Evaluation of treatment strategies and outcomes reported globally.

Main Results:

  • Orbital parasitic infections present with diverse clinical signs, often non-specific.
  • Geographical distribution varies depending on the specific parasite.
  • Treatment approaches range from antiparasitic medication to surgical intervention, with outcomes dependent on the causative agent and stage of disease.

Conclusions:

  • Orbital parasitoses require high clinical suspicion due to overlapping symptoms with common orbital pathologies.
  • Comprehensive understanding of epidemiological factors aids in targeted diagnosis.
  • Effective management necessitates prompt and appropriate treatment tailored to the specific parasitic cause.
