The Ocular Consequences and Applicability of Minimally Invasive 25-Gauge Transvitreal Retinochoroidal Biopsy – Corrected Proof

Objective: To determine the applicability and ocular morbidity of the 25-gauge transvitreal retinochoroidal biopsy technique in the management of intraocular tumors.Design: Retrospective, consecutive, observational, single-surgeon case series.Participants: A total of 124 biopsies were performed in 123 patients with intraocular tumors in the posterior segment from January 1, 2009, through December 31, 2011.Methods: The biopsies were performed under general anesthesia with standard 25-gauge vitrectomy equipment. The vitreous body and the retinotomies were left untreated with the exception of 1 patient in whom a complete vitrectomy and oil tamponade were performed. Histopathologic examination of all samples was performed and cytogenetic testing with fluorescence (Read more...)
