Clinical Course Following Intravitreal Bevacizumab Injection in Posterior Placoid Chorioretinitis

ABSTRACT

PURPOSE: To report the clinical course with optical coherence tomography findings following intravitreal bevacizumab injection in patients with posterior placoid chorioretinitis due to latent syphilis. CASE SUMMARY: A 43-year-old woman presented with visual dimness in the right eye 3 days in duration. Fundus examination showed yellow, placoid lesions in the right eye and there was no cell reaction in the anterior chamber and vitreous. An intravitreal bevacizumab injection was given and systemic work-up performed. After 1 week, the macular lesion disappeared. However, photoreceptor disarrangement was present on spectral-domain optical coherence tomography image. On serologic test, the Venereal Disease Research Laboratory test, and fluorescent treponemal antigen absorption test were positive. She was referred to a division of infectious diseases and confirmed as latent syphilis. The patient received intramuscular penicillin 3 times weekly. Visual acuity and outer retinal abnormality further improved and there was no recurrence during the 6-month follow-up. CONCLUSIONS: Intravitreal bevacizumab injection added to antibiotic treatment may be considered for treating patients with posterior placoid chorioretinitis. Further studies are necessary to evaluate precise disease mechanisms and treatment.
