Healon(R), a viscoelastic preparation of Sodium hyaluronate, has been
reported effective in posterior segment surgery for dissection of epir
etinal membranes, i.e. proliferative diabetic retinopathy and macular
pucker. A more viscous substance might be more effective for this kind
of surgery. Therefore, a new Sodium hyaluronate preparation Healon(R)
GV with a ten times greater viscosity at rest than Healon(R), was tes
ted in and open clinical study. Twenty-four patients of both sexes and
not younger than 18 years were enrolled. The follow-up time was three
months. The main indications for using Healon(R) GV were: to separate
membranes from the retina, to stop bleeding and to reposition a detac
hed retina. 0.2-0.5 ml of Healon(R) GV was injected through a 27 gauge
bent cannula and at close of surgery irrigated out of the eye. Postop
eratively the patients were monitored concerning intraocular pressure,
vitreous clarity, anterior chamber flare and visual acuity. Healon(R)
GV was found to make the surgical procedure simpler and safer. No inf
lammatory reaction and no increase of IOP was observed.
