Abstract
Background
To report the incidence of posterior vitreous detachments (PVDs) and the surgical results of vitrectomy with intravitreal triamcinolone acetonide (TA) to detect vitreomacular adhesions in eyes with asteroid hyalosis (AH).
Methods
Ten eyes of nine patients with AH underwent vitrectomy, six eyes with TA and four without TA. The presence of a PVD was determined preoperatively by ultrasound echography (USE) and intraoperatively by microscopic observations. The postoperative best-corrected visual acuities (BCVA) were evaluated.
Results
The BCVA was improved by >2 Snellen lines in nine eyes and maintained at 20/20 with symptomatic improvements in the other eye. A vitreomacular adhesion was clearly seen during TA-assisted vitrectomy, and none was seen when TA was not used, even though preoperative USE showed an incomplete PVD in all eyes. The BCVA was not significantly better in eyes with TA-assisted vitrectomy than without TA-assisted vitrectomy. In one eye with vitrectomy without TA, a second surgery was required for a persistent cystoid macular edema and an epiretinal membrane. The BCVA and the edema in this eye improved after removing the epiretinal membrane.
Conclusions
All (ten) of the eyes with AH were found to have a vitreomacular adhesion by preoperative USE and intraoperative microscopic observations. The residual vitreous over the macula is more easily detected and removed after intravitreally injected TA, but the visual acuities were not significantly different from eyes without TA.
