Common and rare complications following filtering surgery for children with congenital glaucoma; a5 years study.

PURPOSE: To determine the incidence of postoperative complications following combined trabeculotomy trabeculectomy with mitomycin C (CTTM) for congenital glaucoma (CG), in addition to documentation of some unusual complications and possible ways to manage these complications safely with minimal morbidity.

METHODS

A retrospective observational study was performed on 190 eyes with CG had a CTTM procedure.Included eyes were operated upon between February 2015 and February 2020 in Sohag University Hospitals. Medical records were reviewed and postoperative complications were reported. Incidence of postoperative complications and their management were the main outcome measures.

RESULTS

Early complications developed the form of shallow anterior chamber (AC) (16.3%), hyphema (10.5%), serous choroidal detachment (2%), hemorrhagic choroidal detachment (2%). Unusual and rare complications occurred in the form of iatrogenic Cushing syndrome, unilateral toxic keratopathy developed, vitreous hemorrhage (VH), intercalary staphyloma and decompression retinopathyLate complications included: high postoperative intraocular pressure (IOP) (16.5%), thin cystic blebs (13.1%), hypotony disc edema (2%), cataract (3.2%), one eye developed blebitis and one eye developed endophthalmitis.

CONCLUSION

Surgical management of CG is full of complications in early and late postoperative periods such as shallow AC, hyphema and thin cystic blebs. Some unusual and rare complications developed such as iatrogenic Cushing syndrome, unilateral toxic keratopathy, vitreous hemorrhage, intercalary staphyloma and decompression retinopathy. If identified early; all these complications could be managed properly leading to a successful and favorable outcome.
