To report on the indications, outcomes, and complications of endoscopic vitrectomy (EV) in a large cohort of pediatric vitreoretinal patients. Prior case series have described endoscopic vitreoretinal surgery predominantly in adult patients with a limited range of indications. Here we describe our experience with EV in a diverse group of patients and pathologies, including those without anterior segment comorbidities.
Retrospective review of all patients who underwent posterior vitrectomy at Children’s Hospital Los Angeles (CHLA) from 2012-2017. 154 eyes of 125 patients underwent 210 endoscopic vitrectomies using 23-gauge vitrectomy and 19-gauge endoscopy, of which 209 were via the pars plicata/pars plana and 1 was clear corneal. Data collected included demographics, prior ocular histories, pre-operative and post-operative eye exams, and intraoperative techniques. The study was approved by the Institutional Review Board of CHLA (IRB#16-00103).
Out of 210 surgeries on 154 eyes, the most common pre-operative diagnoses were trauma (24%), retinopathy of prematurity (20%), and pars planitis (7%). At presentation, 68% of eyes had no prior surgery (105/154), 23% had 1 prior surgery (36/154), and 8.4% had 2-11 prior surgeries (13/154). Common indications were tractional (107/210; 51%) and rhegmatogenous (60/210; 29%) retinal detachments. Concurrent procedures included silicone oil placement (95/210; 45%), lensectomy (65/210; 25%), and scleral buckling (25/210; 12%). The mean number of surgeries per eye performed at our center was 3.2 (range: 1-11) with a median follow up since last surgery of 4 months (range: 1 month-6 years). Of 103 eyes with pre-operative retinal detachment, including previously operated eyes, anatomic success as defined by retinal attachment with intraocular pressure > 6 mmHg at last follow up was achieved in 63.1% (65/103). The most common postoperative complications were band keratopathy (19/154; 12%) and cataract (14/154; 9%).
In this large series of pediatric endoscopic vitreoretinal surgeries, there were good anatomic outcomes and complication rates comparable to previous studies. The endoscope is a valuable surgical visualization instrument with wide applicability especially in pediatric eyes with complex retinal pathology.
