    Background/objectives To determine the role of vitreoretinal surgery (VRS) for two different forms of posterior persistent fetal vasculature syndrome (PFVS); with tent-shaped tractional retinal detachment (TRD) and closed funnel-shaped TRD. Subjects/methods Retrospective, single surgeon, consecutive case series of 52 eyes of 44 patients with posterior PFVS who underwent VRS. Cases were divided into "tent-shaped TRD" and "funnel-shaped TRD" groups based on the preoperative TRD configuration. Associated anomalies, functional and anatomical outcomes were evaluated. The cosmetic appearance was defined as poor if there was phthisis bulbi, gross buphthalmos, or corneal opacification; acceptable if there was apparent leukocoria; and excellent if none were noted at the last follow-up. Results Thirty eyes of 29 patients presented with tent-shaped TRD; 70% of which obtained counting fingers or better vision and 90% showed significant reversal of tenting achieving retinal reattachment. The cosmetic appearance was excellent in 87%. Two eyes (7%) became phthisic. Twenty-two eyes of 15 patients presented with funnel-shaped TRD and leukocoria; 45% achieved LP vision and 70% of patients with bilateral pathology had LP in at least one eye. The cosmetic appearance was acceptable to excellent in 73%. Three eyes (14%) became phthisic, one (5%) of which required enucleation. The median follow-up time was 16 (6-71) months. Conclusions VRS often provides functional vision and anatomy in posterior PFVS with tent-shaped TRD morphology. In the funnel-shaped TRD morphology, where no treatment has historically been recommended, surgery may be considered with an aim of restoring light perception and globe preservation, particularly in bilateral cases.

    Outcomes of Gonioscopy-Assisted Transluminal Trabeculotomy in Children with Early-Onset Glaucoma Secondary To Sturge-Weber Syndrome
    (Elsevier, 2025) Aktas, Zeynep; El Sayed, Yasmine; Ucgul, Ahmet Yucel; Gawdat, Ghada; Elhilali, Hala; Aboalazayem, Fayrouz
    Purpose: To evaluate the effectiveness and safety of gonioscopy-assisted transluminal trabeculotomy (GATT) in managing early-onset glaucoma secondary to Sturge-Weber syndrome (SWS). Design: A retrospective interventional case series. Participants: Medical records of 16 patients (22 eyes) diagnosed with early-onset glaucoma secondary to SWS who underwent GATT surgery were reviewed. Methods: All patients underwent GATT surgery using a 5-0 or 6-0 prolene suture under general anesthesia. Main Outcome Measures: The primary outcomes were intraocular pressure (IOP) reduction, complete surgical success (IOP <= 18 mmHg without medications), qualified surgical success (IOP <= 18 mmHg with medications), and postoperative complications. Results: The mean IOP decreased significantly from 25.4 +/- 4.8 mmHg at baseline to 15.7 +/- 4.2 mmHg at the final follow-up (P < 0.001), representing a 38.19% reduction. The mean age at the time of GATT surgery was 33.6 +/- 33.9 months. The mean follow-up duration was 16.3 +/- 6.4 months. Complete surgical success was achieved in 45.4% of eyes (10 out of 22), while qualified success was reached in 81.8% of eyes (18 out of 22). Despite the overall success, 18.1% of eyes (4 eyes) required additional surgical interventions during the follow-up period. These included Ahmed glaucoma valve implantation in 1 eye, trabeculectomy in 2 eyes, and transscleral diode laser cyclophotocoagulation in 1 eye. Transient hyphema was the only reported complication, resolving spontaneously within 1 week without further intervention. Conclusions: Gonioscopy-assisted transluminal trabeculotomy appears to be a promising surgical option for managing early-onset glaucoma in patients with SWS, offering significant IOP reduction and a favorable safety profile within the limitations of our study. However, further studies with longer follow-up periods and comparative groups are necessary to confirm these findings.
