Keratitis due to Acanthamoeba castellani. A clinicopathologic case report
Archives of Ophthalmology (Chicago, Ill. : 1960)
|March 1, 1980
Summary
Acanthamoeba castellani, a rare cause of keratitis, was identified in a necrotic cornea. This case highlights diagnostic challenges and limited treatment success for this serious eye infection.
Area of Science:
- Ophthalmology
- Infectious Diseases
- Microbiology
Background:
- Acanthamoeba keratitis is a severe corneal infection often associated with contact lens wear.
- Diagnosis can be challenging due to non-specific clinical signs.
- Medical therapy for Acanthamoeba keratitis has historically shown limited efficacy.
Observation:
- Trophozoites and cysts of amebas were identified within the necrotic cornea of an enucleated human eye.
- The causative organism was confirmed as Acanthamoeba castellani using indirect immunofluorescent staining with specific antiserum.
Findings:
- The presence of Acanthamoeba castellani in corneal tissue confirms its role in the observed necrosis.
- The case underscores the difficulty in achieving early clinical diagnosis of Acanthamoeba keratitis.
- The findings are consistent with previous reports on the limited effectiveness of medical treatments.
Implications:
- This case emphasizes the need for increased awareness among clinicians regarding rare causes of microbial keratitis.
- Improved diagnostic methods and novel therapeutic strategies are crucial for managing Acanthamoeba keratitis.
- Early recognition and prompt, appropriate treatment are vital to prevent severe visual impairment or loss.

01:25Glaucoma: 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...
01:28Angle 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...
01:27Cryptococcal 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,...
01:28Amebiasis
Entamoeba histolytica, a protozoan parasite, is responsible for intestinal and extraintestinal amebiasis. Though a significant proportion of infections remain asymptomatic, approximately 50 million individuals annually are estimated to present with clinical disease, resulting in up to 100,000 deaths globally. The disease burden is disproportionately high in regions with lower socioeconomic status, such as parts of India, Africa, Mexico, and Latin America.Etiology and TransmissionThe infective...
01:19Encephalitis l: Introduction
Encephalitis is inflammation of the brain parenchyma, most often due to infections or autoimmune processes. It presents with neuropsychiatric features such as fever, altered mental status, behavioral changes, cognitive dysfunction, seizures, focal deficits, and sometimes autonomic instability. In some cases, the meninges are also involved, resulting in meningoencephalitis.Infectious CausesInfectious encephalitis is most commonly viral but can also result from bacterial, fungal, or parasitic...
01:26Brain Abscess l: Introduction
A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial infections,...
