Fluorescein staining of the cornea is usually performed and may provide additional information about other factors, such as the presence of dendrites, pseudodendrites, loose or exposed sutures, foreign body, and any epithelial defect. [8] Fluorescein staining may reveal characteristic findings, such as the dendritic ulcer of herpes simplex virus infection.

Additional tips

Always examine the contralateral eye.

In a patient who cannot sit up in a slit lamp, and a portable slit lamp is not available, a Wood lamp may be the only available tool for fluorescein examination.
