The aim of this article is to present the current data with regard to the application of vital dyes during vitreoretinal surgery, 'chromovitrectomy', as well as to overview the current literature regarding the properties of dyes, techniques of application, indications and complications in chromovitrectomy. It is well known that indocyanine green is toxic to the retina and consequently not the ideal dye for chromovitrectomy. Different vital dyes has been tested for chromovitrectomy including trypan blue, patent blue, triamcinolone acetonide, infracyanine green, sodium fluorescein and brilliant blue. Brilliant blue seems to be the ideal dye for internal limiting membrane due to its afinity, lower toxic profile and to reduce the appearance of apoptosis. Besides the dye itself, the injection technique is crucial to avoid additional toxicity, slow injection, far from the retina and protection of the macular hole are some tips. More recently the use of dyes has been applied to stain perfluorcarbon liquids that may enhance its visualization during vitrectomy.

Vital dyes contain complex molecules with chromophores that stain living tissues and have greatly enhanced identification and removal of transparent vitreoretinal tissues during surgery. Several "chro...

To report neurotrophic keratopathy after vitreoretinal surgery combined with aggressive photocoagulation.
To evaluate the initial experiences of several vitreoretinal surgeons in Brazil, both experienced and beginners, with a three-dimensional (3D) system, and to report the advantages and disadvantages of...
Our research group tested the toxicity of different dye concentrations extracted from the acai fruit using a rabbit model. The dye extracted from the acai fruit in concentrations of 10% an...
Purpose: To establish the prevalence of anticoagulant, aspirin, and clopidogrel use in patients undergoing vitreoretinal surgery, and to compare the outcome of peribulbar anesthesia betwee...
The idiopathic macular hole, age-related disease, is a major cause of vision loss and affects at least two persons in 1000 after 40 years. This hole causes an acute decline linked to a ce...
Operations in the retina and removal of the vitreous (vitrectomy) is a type of operation where the surgeon requires much training and where there is an increased risk of operative complica...
Postoperative pain (POP) is frequently underestimated in general and little data are available particularly for POP after vitreoretinal surgery (VRS). The investigators will conduct a 1-ye...
Sulfur hexafluoride. An inert gas used mainly as a test gas in respiratory physiology. Other uses include its injection in vitreoretinal surgery to restore the vitreous chamber and as a tracer in monitoring the dispersion and deposition of air pollutants.
Specialized ophthalmic technique used in the surgical repair and or treatment of disorders that include retinal tears or detachment; MACULAR HOLES; hereditary retinal disease; AIDS-related retinal infections; ocular tumors; MACULAR DEGENERATION; DIABETIC RETINOPATHY; and UVEITIS.
Dyes used as cosmetics to change hair color either permanently or temporarily.
Green dyes containing ammonium and aryl sulfonate moieties that facilitate the visualization of tissues, if given intravenously. They have mostly been used in the study of kidney physiology.
Agents that emit light after excitation by light. The wave length of the emitted light is usually longer than that of the incident light. Fluorochromes are substances that cause fluorescence in other substances, i.e., dyes used to mark or label other compounds with fluorescent tags.
Surgery is a technology consisting of a physical intervention on tissues. All forms of surgery are considered invasive procedures; so-called "noninvasive surgery" usually refers to an excision that does not penetrate the structure being exci...
