Bilateral Combined Rhegmatogenous and Tractional Retinal Detachments Due to Persistent High-Titer Syphilis

Abstract

A 23-year-old man developed bilateral rhegmatogenous retinal detachments secondary to high-titer ocular syphilis. The patient's titer increased four-fold after completing a 14-day course of intravenous penicillin (IVP). He underwent bilateral pars plana vitrectomy with silicone oil fill in both eyes. In this article, the authors propose an updated treatment method for patients with advanced ocular syphilis that includes oral doxycycline for 30 days following 14 days of IVP to optimally minimize the patient's infectious burden. Following surgery and this new treatment regime, this patient's best-corrected visual acuity 10 weeks postoperatively measured 20/50 in the right eye and 20/30 in the left eye. This case highlights a rare but devastating complication of ocular syphilis. We suggest the addition of oral doxycycline to IVP for patients with syphilis titers ≥ 1:256, HIV co-infection, and presence of posterior retinitis.
