Abstract
Purpose :
The primary objective is to determine the surgical outcome of endoscopic pars plana vitrectomy (PPV) during or shortly after open globe repair. The secondary objective is to detect the number of patients who later required corneal transplantation.
Methods :
This is a retrospective cohort study of patients who received endoscopic PPV during open globe repair or within one month later. Inclusion criteria involved adult patients with a history of open globe injury, corneal opacity, and endoscopic PPV. Data was collected for the period between 12/2018 and 8/2021. Patients with corneal pathology not obliterating the fundus view were excluded from the study. The University of Kansas institutional review board approved this study.
Results :
Ten patients met the study inclusion criteria (3 females, 7 males) with an average age of 61± 22.6 years old. Indications for endoscopic PPV included: retinal detachment in five patients, vitreous hemorrhage in three patients (one with retinal tear, and one with choroidal hemorrhage), and intraocular foreign bodies in two patients. Final visual acuity ranged from 20/70 to no-light-perception (NLP). All patients had their retina successfully attached. Two patients developed phthisis bulbi after one year. Corneal opacity was treated with scleral contact lens in one patient, penetrating keratoplasty in two patients, and the remaining seven patients were deemed unsuitable to receive a corneal transplant due to poor visual potential.
Conclusions :
Endoscopic PPV may be a useful tool to repair posterior segment pathology in patients with recent open globe injury and corneal opacity. It can help address posterior segment disease and postpone corneal transplant surgery until visual potential can be fully determined. A larger prospective study is needed to better elucidate the role of endoscopic PPV in similar patient cohorts.
