Reliability of impression cytology for the diagnosis of ocular surface squamous neoplasia employing the Biopore membrane.
AIM To evaluate the accuracy of impression cytology employing a Biopore membrane device in the diagnosis of ocular surface squamous neoplasia (OSSN). METHODS The histology of patients undergoing excision biopsy for the suspected diagnosis of OSSN over a 20 month period was compared with the reported cytology of impression cytology specimens obtained preoperatively using the Biopore membrane d...
متن کاملUse of impression cytology for the detection of unsuspected ocular surface squamous neoplasia cells in pterygia.
Purpose: To evaluate the agreement between the methodologies of impression cytology (IC) and histopathology regarding epithelial lesions clinically diagnosed as pterygium and also regarding the detection of unsuspected and associated ocular surface squamous neoplasia (OSSN). Methods: Thirty-two Brazilian patients were included and IC was performed on all pterygia before excision. Histopathogica...
متن کاملImpression cytology following mitomycin C therapy for ocular surface squamous neoplasia.
BACKGROUND/AIMS Topical mitomycin C (MMC) therapy has been used for treatment of ocular surface squamous neoplasia (OSSN) since 1994. Relatively few studies have reported the cellular changes in ocular surface following MMC. METHODS Impression cytology was studied in four patients with ocular surface squamous neoplasia, either primary or recurrence after previous excisional biopsy. The author...
متن کاملImpression cytology of the ocular surface.
Impression cytology refers to the application of a cellulose acetate filter to the ocular surface to remove the superficial layers of the ocular surface epithelium. These cells can then be subjected to histological, immunohistological, or molecular analysis. Proper technique is essential as the number of cells sampled can vary considerably. Generally two to three layers of cells are removed in ...
متن کاملOcular Surface Squamous Neoplasia
The ocular surface is composed of the conjunctiva and the cornea. The conjunctiva is a mucous membrane which covers the globe and inner part of the eyelids. The morphology of conjunctival epithelial cells are nonkeratinized stratified epithelia which vary from cuboidal over the tarsus, to columnar in the fornices, to squamous epithelia on the globe. Goblet cells account for up to 10% of the bas...
