Background: To evaluate the effectiveness of bent angle needle
goniectomy (BANG) in treating congenital glaucoma, whether as
a primary or secondary treatment following previous failure
surgeries. Methods: This study focused on paediatric glaucoma
patients who underwent BANG at the Benha Glaucoma Unit
between 2020 and 2023. Patients were divided into two groups:
Group A; included patients who underwent BANG as a primary
procedure, while Group B; comprised patients who had BANG
as a secondary procedure. Group A was divided into neonatal
(A1) and infantile (A2) categories. Group B was subdivided into
the post-trabeculotomy group (B1) and the post-trabeculectomy
group (B2). Success was determined by an intraocular pressure
(IOP) of 20 mmHg or less, with or without medications. Results:
Forty-eight eyes of thirty-nine children were examined. Both
groups experienced a significant reduction in intraocular pressure
(IOP) after BANG. At the end of one year of follow-up, groups
A and B showed reductions in IOP of 52.4% and 50.1%
respectively. Success rates for primary and redo surgeries were
75% and 62.5% respectively. The success rate was higher in
group A2 (81.25%) compared to group A1 (62.5%). Conversely,
post-trabeculotomy was more successful (64.28%) than posttrabeculectomy (60%). The failure rate was higher in eyes with
higher baseline IOP, longer axial length, larger corneal diameter
and positive consanguinity. There were no significant
intraoperative or postoperative complications. Conclusion:
BANG is an effective surgery for managing paediatric glaucoma.
It can also be used as a secondary surgery following unsuccessful
previous procedures |
