K. Kadonosono et al., Iris neovascularization after vitrectomy combined with phacoemulsificationand intraocular lens implantation for proliferative diabetic retinopathy, OPHTHAL SUR, 32(1), 2001, pp. 19-24
PURPOSE: To analyze the incidence of iris neovascularization after vitrecto
my combined with phacoemulsification and intraocular lens (IOL) implantatio
n using a small incision in the treatment of proliferative diabetic retinop
PATIENTS AND METHODS: We studied a consecutive series of 46 eyes in which v
itrectomy combined with phacoemulsification and IOL implantation had been p
erformed, and compared the surgical results with a prior series of 40 eyes
in which vitrectomy alone had been performed.
RESULTS: Postoperative iris and angle neovascularization was found in 6 eye
s (15%) treated by vitrectomy alone, but in only 1 eye (2%) treated by comb
ined vitrectomy (P<0.05). Final visual acuity improved by two or more lines
in 23 eyes (57%) in the vitrectomy alone group, and in 35 eyes (76%) in th
e combined vitrectomy group.
CONCLUSIONS: The incidence of postoperative rubeosis iridis was significant
ly lower, and the visual results were satisfactory with vitrectomy combined
with phacoemulsification and IOL implantation for PDR These findings sugge
st thr combined vitrectomy for PDR is a useful surgical procedure.
