Micropunctate fluorescein staining of the human corneal surface: microerosions or cystic spaces? A non-contact photomicrographic in vivo study.
OBJECTIVE
To study in vivo the phenomenon of micropunctate fluorescein staining of the human corneal surface.


METHODS
Patients were examined in the slit-lamp and photographed by the means of photomicrography. The staining pattern of fluorescein was compared with that of superimposed rose bengal staining.


RESULTS
The staining patterns showed a great correspondence.


CONCLUSIONS
The findings indicate that micropunctate fluorescein staining probably reveals disruptions of intercellular junctions permitting penetration and accumulation of stained fluid beneath diseased cells in situ.
