Abstract
Diferentes aplicações do azul de tripano (AT) foram descritas para cirurgia intraocular, com elevados patamares de eficácia e segurança. Neste relato, é descrito a aplicação do AT como corante vital para superfíce ocular, de modo a estudar a integridade das células da superfície corneana e conjuntival na superfície ocular. Tal abordagem permite um diagnóstico mais sensível de desordens da superfície ocular, destacando-se disfunção lacrimal ou síndrome do olho seco. O AT tem propriedades distintas da fluoresceína, com a qual se [...]

METHODSUbiquitous in ophthalmology, vital dyes that stain living tissues including trypan blue, fluorescein, rose bengal, indocyanine green and lissamine green have all facilitated diagnostic and surgical techniques
Trypan blue (TB) dye was first introduced in cataract surgery by Melles[2], and was advocated for all cataract cases in Brasil by Dr Carlos G
Our group adopted this approach in cataract surgery, and it was incidentally noted that TB dye would stain conjunctival and corneal surfaces, in those with poor ocular surfaces
Summary
Ubiquitous in ophthalmology, vital dyes that stain living tissues including trypan blue, fluorescein, rose bengal, indocyanine green and lissamine green have all facilitated diagnostic and surgical techniques. Trypan blue (TB), an anionic hydrophilic azo dye, is in wide use for staining the capsule during cataract surgery and aiding vitreoretinal surgery[1]. Our group adopted this approach in cataract surgery, and it was incidentally noted that TB dye would stain conjunctival and corneal surfaces, in those with poor ocular surfaces.
