Abstract :
Purpoe
To identify preoperative, perioperative, and potoperative rik factor for cleral buckle (B) removal.
Deign
Retropective, conecutive, matched, cae-control tudy.
Method
Cae included all patient undergoing B removal between Augut 1988 and December 2007 at a ingle academic center. Cae were matched againt four randomly elected control patient who underwent B implantation during the ame year a the cae. Odd ratio (OR) were calculated for each factor invetigated.
Reult
Forty cae of B removal and 148 matched control cae were identified. Three cae of B removal were omitted from analyi becaue of incomplete record. Factor aociated with B removal for any reaon, uing univariate analyi, included concurrent globe-penetrating injury at time of B placement (OR, 24; 95% confidence interval [CI], 2.9 to 200), concurrent par plana vitrectomy (PPV) (OR, 17.3; 95% CI, 4.9 to 61), diabete mellitu (DM) (OR, 7.3; 95% CI, 1.8 to 30), prior chronic topical ocular therapy (OR, 4.3; 95% CI, 1.7 to 11), and ubequent ocular procedure (OR, 3.4; 95% CI, 1.5 to 7.5). Factor independently aociated with B removal uing multivariate analyi included concurrent globe-penetrating injury (OR, 27.3; 95% CI, 1.7 to 426), concurrent PPV (OR, 11.3; 95% CI, 2.9 to 45), DM (OR, 8.9; 95% CI, 1.3 to 58), and ubequent ocular procedure (OR, 3.9; 95% CI, 1.4 to 11). Factor that did not alter B removal rik included patient age; gender; and type, ize, or location of buckling element ued.
Concluion
Awarene of thee rik factor may be valuable for the urgical planning of retinal detachment repair in patient at higher rik for ubequent B removal and for rik tratification ubequent to B implantation.
