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: Aim. To report on the use of indocyanine green (ICG) during surgical removal of pediatric orbital lacrimal duct cysts. Method. We conducted a retrospective review of our cases of surgical excision of orbital lacrimal duct cysts using intraoperative injection of indocyanine green (ICG), which was used following inadvertent cyst rupture and volume loss. The dye allowed complete cyst visualization and complete excision despite volume loss or cyst rupture. Results. The study included 6 children (3 boys, mean age of 4.2 ± 0.84 years, range 3-5 years). Mean follow-up period was 9.3 months. All cysts were located in the inferonasal quadrant of the orbit (4 in the right side). In all cases, ICG was injected into the cyst at the time of surgery following unintentional cyst rupture. After the dye injection, it was easy to identify the borders of the cyst, permitting complete cyst removal, without any intra- or postoperative complications. Pathological examination revealed that all cysts were of lacrimal duct origin. Conclusion. Intraoperative injection of ICG into orbital cysts in children can aid surgeons in identifying cyst borders following inadvertent rupture, allowing complete removal.Journal of Ophthalmology 01/2015; 2015:1-4.
