Abstract
Background
The purpose of this study was to evaluate the incidence and amount of macular edema by optical coherence tomography (OCT) after combined small gauge sutureless vitrectomy with phacoemulsification and intravitreal triamcinolone.
Methods
This retrospective case series included 194 consecutive eyes undergoing nonemergent vitrectomy with phacoemulsification and intravitreal triamcinolone. Ninety-one eyes had preoperative and postoperative OCT available and were included in the analysis. The eyes were evaluated for retinal thickness with preoperative and postoperative OCT, and for preoperative and postoperative best-corrected visual acuity. The main outcome measures were retinal thickness, OCT appearance, and best-corrected visual acuity.
Results
The incidence of macular edema in all eyes preoperatively was 64.8% and postoperatively was 50.5%. Mean central subfield and center point thickness in eyes with macular edema preoperatively were 361 μm and 349 μm, respectively, and postoperatively were 315 μm and 304 μm, respectively. In eyes without preoperative macular edema, mean preoperative central subfield and center point thickness were, respectively, 210 μm and 181 μm versus 220 μm and 192 μm postoperatively. Best corrected visual acuity improved from 20/190 preoperatively to 20/150 at postoperative month 1 and 20/110 at month 6. Postoperative intraocular pressure ≥ 25 mmHg was observed in 7.7% of eyes, none of which required surgical intervention for steroid-induced glaucoma.
Conclusion
Use of intravitreal triamcinolone with combined vitrectomy and phacoemulsification may play an important role in modulating postoperative macular edema. Adverse pressure rise is infrequent and usually limited.
