Visualization of conjunctival cyst using Healon V and trypan blue.
ABSTRACT To report a new modified method using the mixture of an ophthalmic viscosurgical devices (Healon V) and trypan blue solution to facilitate complete removal of a conjunctival cyst.
A 54-year-old woman was referred to us for removal of a conjunctival cyst in her right eye. To achieve a complete removal of the conjunctival cyst, a mixture of Healon V and trypan blue solution was injected through a 27-gauge needle into the cyst.
This new technique achieved excellent visualization with an easy and complete resection of the cyst.
The mixture of Healon V and trypan blue is effective in delineating the capsule while preserving its integrity during removal. Such a technique may also have a role in facilitating visualization and excision of other cystic conjunctival lesions.

ABSTRACT: Cataract surgeons should employ all reasonable technology to facilitate safe and consistent outcomes. Knowledge of adjunct devices to enhance visualization of the capsular bag and appropriate use of ophthalmic viscosurgical devices allow for enhanced protection of intraocular structures and reduced rates of complication. Trypan blue is US Food and Drug Administration-approved for facilitating visualization of the anterior capsule. Animal data demonstrate Brilliant Blue G to be an effective capsular stain with a superior safety profile. Healon5 is a safe viscosurgical device that is particularly useful in children, poorly dilating pupils, intraoperative floppy-iris syndrome, and intumescent cataracts. The viscoadaptivity of Healon5 enables its utility throughout the procedure of cataract extraction. The recent literature on capsular dyes and advances in ophthalmic viscosurgical technology is reviewed. Inadequate capsular visualization and poor tissue stabilization/protection increase the chance of discontinuous capsulorhexis, retained nuclear material, vitreous loss and corneal decompensation. Utilization of adjunctive tools in the setting of challenging cataract cases can significantly limit adverse intraoperative outcomes and result in reproducible surgical success.Current Opinion in Ophthalmology 03/2007; 18(1):52-7.
