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...
Cryptococcal Meningitis01:27

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,...
Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

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...
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...

Area of Science:

  • Ophthalmology
  • Infectious Diseases
  • Mycology

Background:

  • Coccidioidomycosis is a fungal infection endemic to arid regions of the Americas.
  • Intraocular involvement of Coccidioidomycosis is rare but can present with diverse clinical manifestations.
  • Distinguishing fungal endophthalmitis from intraocular neoplasms is crucial for appropriate management.

Observation:

  • A 10-year-old girl presented with symptoms suggestive of an intraocular tumor.
  • Ophthalmologic examination revealed a blind and painful eye.
  • Histopathological examination of the removed eye confirmed Coccidioidomycosis infection.

Findings:

  • The intraocular mass was definitively diagnosed as Coccidioidomycosis, not a neoplasm.
  • The fungal infection led to irreversible vision loss and ocular pain.
  • Enucleation was performed due to the severity and non-treatable nature of the intraocular infection.

Implications:

  • This case highlights the importance of considering Coccidioidomycosis in the differential diagnosis of intraocular masses, especially in endemic areas.
  • Early recognition and appropriate treatment of ocular Coccidioidomycosis can potentially prevent severe complications like blindness and the need for enucleation.
  • Further research into diagnostic modalities and therapeutic strategies for intraocular fungal infections is warranted.
