Anatomical and functional outcomes following vitrectomy for dense vitreous hemorrhage related to Terson syndrome in children.

Abstract

Our purpose was to assess anatomical and functional outcomes of vitrectomy in pediatric cases of Terson syndrome. A total of 11 eyes of seven children diagnosed with Terson syndrome secondary to traumatic brain injury and 17 eyes of 12 children diagnosed with Terson syndrome secondary to nontraumatic brain hemorrhage who had 20-gauge or 23-gauge pars plana or pars plicata vitrectomy were included in this retrospective study. The primary outcome was the change in visual acuity from the preoperative examination to postoperative final follow-up. Secondary outcomes were anatomic surgical success and postoperative complications. The mean time between diagnosis and surgery was 62 ± 35days (range, 30-150), and the average age at the time of the surgery was 4.5 ± 6.4years (range, 3months to 17years). The mean preoperative logarithm of the minimum angle of resolution (logMAR) (Snellen) best corrected visual acuity (BCVA) was 2.6 ± 0.7 (20/7260) (n = 9) and in the remaining 19 eyes it was recorded as noncentral, unsteady, nonmaintained fixation. The mean follow-up period was 50 ± 54months (range, 12-192months). At the last follow-up visit, the mean logMAR BCVA was 0.46 ± 0.6 (20/60) (n = 19) and in eight eyes it was recorded as fix-and-follow. One eye developed a retinal detachment 14months after the first operation, and one eye developed an epiretinal membrane after 2years. Anatomical success was recorded in all patients at the final visit. In children with massive vitreous hemorrhage secondary to Terson syndrome, vitrectomy is an effective procedure and offers a rapid visual improvement. Earlier surgical treatment prevents amblyopia and blood-related potential complications.
