Acanthamoeba Keratitis With Granulomatous Reaction Involving the Stroma and Anterior Chamber

A Synthetic View on Acanthamoeba Keratitis Host Immune Response: Potential Factors Influencing the Development of Chronic Inflammation

“…Among other cells that have been reportedly found in AK lesions are also histiocytes 34,39,44,45 and eosinophils. 46,47…”

“…Despite this, one of the great difficulties in AK treatment is the severe and chronic inflammatory complications that may develop, often in the presence of granulomatous and necrotizing inflammation and leukocyte infiltration. 32–34,37,39,44,45,47,56,75,76…”

“…Among other cells that have been reportedly found in AK lesions are also histiocytes 34,39,44,45 and eosinophils. 46,47 In addition, in a review by Li and Sun, 48 the authors suggest that one of the factors that make CL wearers more susceptible to AK is that extended CL use impairs innate immunity in the ocular surface by decreasing cytokine and polymorphonuclear cells response.…”

Incidence and Risk Factors of Ocular Hypertension and Glaucoma in Patients With Acanthamoeba Keratitis

“…In the setting of an Acanthamoeba infection, multiple mechanisms can explain the occurrence of glaucoma such as steroid response, granulomatous anterior chamber inflammation, 7 peripheral anterior synechiae leading to secondary angle closure, elevated episcleral venous pressure as a result of acanthamoeba scleritis, and impaired outflow caused by Acanthamoeba cysts invading ocular tissue. 8 In all of our patients, the first instance of elevated IOP was documented during follow-up, and not at the time of presentation.…”

Granulomatous inflammation in Acanthamoeba sclerokeratitis

“…[56] Granulomatous inflammation has previously been reported in Acanthamoeba keratitis. [78] Its mechanism in corneal infections is presumed to be either an immunological response to host antigens that becomes altered and or exposed by the infective and inflammatory processes, or a response to antigens from the infectious agent itself. [8910]…”
