Comparison of 20- and 25-gauge vitrectomy for primary repair of rhegmatogenous retinal detachment.
OBJECTIVE
To evaluate the outcome of 25-gauge transconjunctival pars plana vitrectomy and compare it with that of 20-gauge pars plana vitrectomy for primary repair of rhegmatogenous retinal detachment.


METHODS
A retrospective study of a consecutive series of 166 eyes of 164 patients who underwent pars plana vitrectomy for primary rhegmatogenous retinal detachment was performed. One hundred nineteen eyes underwent 25-gauge vitrectomy and 47 eyes underwent 20-gauge vitrectomy.


RESULTS
The anatomic success rates after the initial surgery in the 25-gauge vitrectomy and 20-gauge vitrectomy groups were 93.3% and 91.5%, respectively. The median visual acuity improved significantly from 20/80 preoperatively to 20/30 postoperatively in the 25-gauge group, and from 20/90 to 20/30 in the 20-gauge group.


CONCLUSIONS
Good anatomic and functional results were achieved with 25-gauge vitrectomy and the outcomes compared favorably with those of 20-gauge vitrectomy for the treatment of rhegmatogenous retinal detachment.
