New Freeware for Image Analysis of Lissamine Green Conjunctival Staining.

Purpose: Lissamine green (LG) is often used in addition to fluorescein to assess the severity of conjunctival damage in dry eye syndrome, which is graded manually. Our purpose was to describe an algorithm designed for image analysis of LG conjunctival staining.

Methods: Twenty pictures of patients suffering from dry eye with visible LG conjunctival staining were selected.

Dermoscopy for the Diagnosis of Conjunctival Lesions.

This article describes the present literature on dermoscopy of conjunctiva and shows the results of a dermoscopy study of 147 conjunctival tumors. Melanomas were characterized by a heavy pigmentation, irregular dots, and a higher prevalence of gray color compared with nevi. Squamous cell carcinomas had peculiar hairpin and glomerular vessels.

Micro-instillation of fluorescein with an inoculation loop for ocular surface staining in dry eye syndrome.

Purpose: To describe and validate the micro-instillation of fluorescein on the ocular surface by a disposable calibrated inoculation loop to improve corneal and conjunctival staining quality.

Methods: Accuracy and precision of the volume of 0.5% sodium fluorescein collected by a single use 1 μl-calibrated inoculation loop were measured using a precision balance.
