Abstract

Insights

Ophthalmic aspergillosis, a fungal infection, can cause severe eye inflammation and vision loss, particularly in immunocompromised individuals. Early diagnosis and treatment are crucial but often associated with poor outcomes.

Area of Science:

  • Ophthalmology
  • Mycology
  • Infectious Diseases

Background:

  • Aspergillus species are ubiquitous fungi that rarely cause disease in immunocompetent individuals.
  • Ophthalmic aspergillosis occurs when the immune system is compromised, leading to invasive infections of the eye.

Observation:

  • A case series of three female patients with a history of methylprednisolone use presented with ophthalmic aspergillosis.
  • Two patients developed endogenous endophthalmitis, one with acute retinal necrosis-like syndrome, and both succumbed to disseminated disease.
  • The third patient presented with sino-orbital aspergillosis, leading to vision loss despite treatment.

Findings:

  • Ophthalmic aspergillosis can manifest as acute endophthalmitis or indolent sino-orbital disease.
  • Diagnosis involved serum testing or vitrectomy cultures.
  • Treatment with antimycotics showed limited efficacy, with high rates of morbidity and mortality.

Implications:

  • This condition highlights the severe visual and systemic consequences of Aspergillus invasion in compromised hosts.
  • Prompt recognition of both intraocular and sino-orbital forms is critical for patient management.
  • The poor prognosis underscores the need for improved therapeutic strategies for ophthalmic aspergillosis.

Skin Diseases and Disorders

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

Cryptococcal Meningitis

Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...

Fungal Phylum Ascomycota

Phylum Ascomycota, a major division within the subkingdom Dikarya, comprises a diverse range of fungal species, including both unicellular yeasts and filamentous molds such as Aspergillus and Penicillium. These fungi thrive in a variety of habitats, from aquatic ecosystems to terrestrial environments, playing crucial ecological and economic roles.Morphology and ReproductionThe defining characteristic of Ascomycetes, commonly referred to as sac fungi, is the ascus—a sac-like structure that...
Glaucoma: Overview01:25

Glaucoma: Overview

Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...
Open Angle Glaucoma: Treatment01:27

Open Angle Glaucoma: Treatment

In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.
Drugs such as carbonic anhydrase inhibitors, α2- and...
Antifungal Agents01:15

Antifungal Agents

Amphotericin B is a broad-spectrum antifungal agent that exploits structural differences between fungal and mammalian cell membranes. Its amphipathic structure—featuring a hydrophobic polyene-lactone ring and a hydrophilic region containing mycosamine and carboxylic acid groups—enables selective binding to ergosterol, a sterol predominantly found in fungal plasma membranes. This selective interaction underlies the drug’s antifungal activity, although weak binding to cholesterol contributes to...
