Microbiome of the Eye01:22

Microbiome of the Eye

67
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...

Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

1.6K
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...

Alveolates are a group of organisms recognized by the presence of alveoli, which are cytoplasmic sacs located beneath the cell membrane. While their function remains uncertain, alveoli may help regulate water balance by controlling how much water enters and leaves the cell. In dinoflagellates, these structures may serve as armor plates. There are three major types of alveolates: ciliates, which move using cilia; dinoflagellates, which use flagella for movement; and apicomplexans, which are...

Open Angle Glaucoma: Treatment01:27

Open Angle Glaucoma: Treatment

1.1K
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...

Glaucoma: Overview01:25

Glaucoma: Overview

1.7K
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...

Fungal Phylum Microsporidia01:28

Fungal Phylum Microsporidia

782
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...

Area of Science:

  • Ophthalmology
  • Infectious Diseases
  • Microbiology

Context:

  • Acanthamoeba keratitis is a sight-threatening infection primarily affecting contact lens wearers.
  • Clinical manifestations include pseudodendritic epitheliopathy, perineuritis, ring infiltrates, and sterile anterior uveitis.
  • Diagnosis relies on methods like polymerase chain reaction (PCR), confocal biomicroscopy, and in vitro cultivation.

Purpose:

  • To outline the clinical presentation, diagnostic methods, and therapeutic strategies for Acanthamoeba keratitis.
  • To highlight the importance of early diagnosis and treatment efficacy.
  • To review conservative and surgical treatment options, including their limitations due to lack of randomized controlled trials.

Summary:

  • Early diagnosis of Acanthamoeba keratitis is critical for successful management.
  • Triple topical therapy with polyhexamide, propamidine isethionate, and neomycin is the primary treatment, often requiring up to one year of application.
  • For refractory cases, surgical interventions such as cryotherapy, amniotic membrane transplantation, crosslinking, and keratoplasty are considered.

Impact:

  • Timely and accurate diagnosis improves patient outcomes and visual prognosis.
  • Effective treatment strategies can prevent severe visual impairment or blindness.
  • Further randomized controlled studies are needed to establish definitive evidence for treatment reliability and efficacy.
