Purpose: To evaluate the effects of subtenon triamcinolone injections in patients with macular edema or low visual improvement after undergoing vitrectomy for treatment of idiopathic epiretinal membrane.
Methods: We conducted a retrospective chart review of 45 eyes of 45 patients who were diagnosed with idiopathic epiretinal membrane and underwent vitrectomy, but did not have more than 0.1 logarithm of the minimum angle of resolution (logMAR) increase in best corrected visual acuity (BCVA) after the operation. Of the 45 patients, 24 patients received 40 mg triamcinolone injection in subtenon space in 2 to 5 months after the operation, and 21 patients received no injection. We analyzed BCVA, central macular thickness (CMT), intraocular pressure (IOP), and complications in 1, 2, 6, and 12 months after the operation.
Results: Before the operation, the mean BCVA and CMT in the injection group were 0.53 ± 0.16 and 616.58 ± 143.44 μm, and those in the non-injection group were 0.51 ± 0.25 and 566.29 ± 116.33 μm, respectively. 12 months after the operation, the mean BCVA and CMT in the injection group improved to 0.24 ± 0.17 and 373.11 ± 80.91 μm and those in the non-injection group were 0.28 ± 0.26 and 354.75 ± 80.03 μm, respectively. The difference between the two groups was not statistically significant. At 6 months postoperatively, the IOP was significantly higher in the injection group than that in the non-injection group.
Conclusions: Patients with idiopathic epiretinal membrane did not show further improvement in BCVA and CMT when they received the subtenon triamcinolone injection after vitrectomy.
