Understanding Corneal Ulcers and Infiltrates - Review of …
2023年11月15日 · Sterile corneal infiltrates may be considered marginal, which are self-limiting hypersensitivity reactions due to Staphylococcal antigens in the setting of bacterial eyelid disease; in these cases, the infiltrates are small, circumlimbal, with a 1mm clear interval, often abutting the eyelid margin with mild focal hyperemia. 10,11 Marginal ...
Intruder Alert: Diagnosing Corneal Infiltrative Disease
2018年1月15日 · Corneal infiltrates represent an immune response to corneal insult, whether from a microbial antigen, contact lens wear or even corneal surgery. A firm grasp of corneal mechanics is a first important step toward understanding how an infiltrate occurs.
Is It an Ulcer or an Infiltrate? - Review of Optometry
2007年7月3日 · There is a clear zone of about 1mm or 2mm of cornea separating the infiltrates and the limbus, although blood vessels may dilate and extend toward the infiltrates in a bridging manner. While the bacteria on the lids are pathogens, the infiltrates and catarrhal ulcers themselves are sterile, caused by antigen-antibody complexes from bacterial ...
What Are Corneal Infiltrates? - All About Vision

Marginal Keratitis - EyeWiki
Marginal keratitis is an inflammatory disease of the peripheral cornea, characterized by peripheral stromal infiltrates which are often associated with epithelium break down and ulceration. It is usually associated with the presence of blepharoconjunctivitis and is thought to represent an inflammatory response against S. aureus antigens.
Characterizing Contact Lens–Related Corneal Infiltrates: A Pilot …
2016年8月24日 · Corneal infiltrative events (CIEs) have become a growing concern for clinicians because of their increased incidence among contact lens wearers. 1 CIEs form from the gathering of leukocytes in the corneal tissue due to inflammation. 2 They can be asymptomatic or symptomatic and categorized as sterile or infectious by the clinician, 3,4 often ...
Sterile Corneal Infiltrates following Cataract Surgery: Case Series
We report a case series of 26 eyes of 26 patients undergoing planned cataract surgery from December 2021 to March 2022, who were diagnosed as having whitish round infiltrates in the surgical corneal incisions. The infiltrates were detected at the first check after 5–8 days from cataract surgery and were located either within the main corneal ...
Management of Small Corneal Infiltrates in Contact Lens Wearers
Although contact lens–associated corneal infiltrates are usually considered sterile in contrast to infected ulcers, they can be sterile or infected. It is important to distinguish infected from sterile infiltrates because the management of the former requires intensive topical antibiotics and the latter may benefit from topical ...
