Abstract
The introduction of micro-incisional vitrectomy surgery induced a paradigm shift in management of vitreoretinal diseases. Vitrectomy in pediatric age group represents a major challenge due to its unique anatomical and pathological considerations.
This was a prospective, comparative non-randomized case series study to compare surgical and clinical outcomes of pediatric retinal detachment repair using 23 gauge (23G) and 25 gauge (25G) vitrectomy. Fifty patients were recruited for the study and divided into two groups. The first group included 25 patients and undergone 23G vitrectomy and the second group included 25 patients and undergone 25G vitrectomy. The main outcome measures were the actual vitrectmy time and need to suture a sclerotomy and the early postoperative hypotony rate.
Analysis of intraoperative data showed that the actual time for vitreous removal was 22.00 ± 5.71 minutes in 23G group compared to 24.13 ± 5.97 minutes in 25G group (P= 0.273). A significant difference was noted between both groups regarding suturing at least one sclerotomy at the end of the surgery with 11 eyes (44%) in 23G group and only 4 eyes (16%) in 25G group, however no significant difference in early postoperative hypotony rate was observed. The visual and anatomical outcomes were comparable between both groups with no significant difference.
Both 23g and 25g systems are highly efficient for the treatment of pediatric retinal detachment. However, Our research showed that operations performed with the 25G system were less likely to demand a suture with earlier visual recovery.
