The most widely used diagnostic tests for tear film examination are tear break-up time (TBUT) test, corneal and conjunctival staining with fluorescein, rose bengal and lissamine green dye, Schirmer test, tear film osmolarity test and impression cytology
refers to the application of cellulose acetate filter paper to the ocular surface to remove the superficial layers of the ocular surface epithelium.
Ocular Surface Disease Index (OSDI) questionnaire, break-up time (BUT) test, corneal fluorescein staining, corneal and conjunctival rose Bengal staining, Schirmer test, and conjunctiva impression cytology
were performed sequentially on days 0 and 91.
Morphological changes of the conjunctival epithelium in contact lens wearers evaluated by impression cytology
with transfer (ICT) test was performed on the entire sample.
with transfer: na easy method for detection of vitamin A deficiency.
Conjunctiva impression cytology
is one of the most practical, fast, safe and economical method to examine the changes of conjunctiva cells.
Staging of conjonctival squamouse metaplasia by impression cytology
The outcome of such an agreement is very promising, thus, the initial results of our collaboration will be presented at the Association for Research in Vision and Ophthalmology (ARVO) 2011 Annual Meeting in May on a poster on the evaluation of membranes material for impression cytology
9) Superficial excision remains the important initial step in management, as it is impossible to exclude invasive disease on clinical grounds or with impression cytology
The technique of impression cytology
was first described by Egbert et al in 1977.
Dry eye was confirmed by ocular surface dye staining pattern with fluorescein, tear film break up time (value 15s), Schirmer's test (positive if 10mm or less in 5min) and conjunctival impression cytology
