ABSTRACT
|
Descemet membrane detachments are not uncommon following cataract surgery,
and large and extensive detachments can have an impressive presentation, with
severe corneal edema and marked reduction in visual acuity. Traditional treatment
regimens have included observation (with the hopes of spontaneous resolution),
anterior chamber injections of air or viscoelastic, transcorneal suturing,
and even corneal transplantation for persistent cases. During the past few
years, intracameral injection with either sulfur hexafluoride (SF6) or perfluoropropane
(C3F8) gas has gained increasing acceptance as an efficient and effective
treatment option for Descemet membrane detachments. Previously described techniques
of gas injection have required corneal and paracentesis incisions; sterile
blades, cannulas, and other instruments; and occasionally, an operating room
setting. We describe a simple, safe, and effective technique for intracameral
gas injection that can be performed by one person at the slitlamp microscope
or in a minor operating room with minimal equipment.
