To evaluate the effect of intraoperative 360 degrees laser retinopexy anterior to the equator for the prevention of rhegmatogenous retinal detachment after vitrectomy.
A consecutive case series of 378 patients (378 eyes) with rhegmatogenous retinal detachment who underwent vitrectomy between July 2001 and June 2007. A consecutive cohort of patients who had undergone vitrectomy and 360 degrees laser to the peripheral retina was identified (n=108) and compared with a control group of patients who had not received laser retinopexy (n=270). For the 360 degrees laser group, three rows of burns were placed between the vitreous base and the equator.
There was no significant difference in baseline characteristics between the two consecutive series (the 360 degrees laser group and the control group). The intraoperative 360 degrees laser group showed a significant reduction (1.9%, 2/108 eyes) in the rate of the incidence of retinal re-detachment after vitrectomy, compared with the control group (7.0% 19/270 eyes) (P=0.04). And there are no significant differences in postoperative visual acuity (log MAR; the laser group:0.03 and the control group:0.05, P=0.49) and in the complications such as epi-retinal membrane(the laser group:3.7% 4/108 eyes and the control group:3.7% 10/270, P=0.99).
Intraoperative 360 degrees laser during vitrectomy showed an reduction in the rate of postoperative retinal detachment without any apparent effects. Considering the vision-threatening nature of retinal re-detachment after vitrectomy, this adjunctive treatment should be considered to be used in vitrectomy procedures.
