Polypoidal choroidal vasculopathy-characteristics and response to treatment with bevacizumab in caucasian patients.

PURPOSE: To investigate the features and treatment response in Caucasian patients with polypoidal choroidal vasculopathy (PCV), initially treated with bevacizumab. METHODS: 45 eyes of 43 treatment-naïve patients with PCV were included in this retrospective study, all uniformly initially treated with three bevacizumab injections monthly. OCT characteristics and clinical parameters were recorded and analyzed at presentation, after the initial 3 bevacizumab injections and at the final follow up period. RESULTS: Following 3 monthly bevacizumab injections visual acuity significantly improved with a mean gain of one line of vision. Central macular thickness (CMT) significantly improved from a mean of 402.1 ± 130.8 µm at presentation to 322.0 ± 96.8 µm (p < 0.01). Subretinal fluid, intraretinal fluid and submacular hemorrhage significantly improved. 53% were later switched to aflibercept and showed better response in the central macular thickness in comparison to those in which bevacizumab injections were continued. No correlation was found between the presence of pachyvessels or increased choroidal thickness and the improvement in VA or CMT. CONCLUSION: Fixed first-line treatment with intravitreal bevacizumab monotherapy in non-Asian PCV patients achieves satisfactory visual and anatomical outcomes.

[OCULAR SYPHILIS].

INTRODUCTION: Syphilis is also known as 'the great imitator' for its ability to mimic many diseases due to its extensive range of clinical manifestations. This review aims to provide an update on the clinical presentation, diagnosis and treatment of ocular syphilis. It manifests in a spectrum of ways that can occur at any stage of the disease, and may be the only presenting feature of systemic syphilis, with the most common finding being panuveitis. The diagnosis is usually aided by serology testing: nonspecific treponemal antibodies (for screening and follow-up) and specific treponemal antibodies for confirmation of the diagnosis. The treatment for ocular syphilis is similar to neurosyphilis and includes intravenous aqueous crystalline penicillin.
