Purpose. To examine choroidal neovascularization (CNV) characteristics in patients with exudative age-related macular degeneration (AMD) and polypoidal choroidal vasculopathy (PCV), using swept-source optical coherence tomography angiography (SS-OCTA), and investigate agreement with OCT B-scan, fundus fluorescein angiography (FFA), and indocyanine green angiography (ICGA) by two different examiners. Methods. This is a retrospective multicentric study that involved patients with a history of AMD and PCV. Examiner A, who had access to OCTA, B-scan OCT, FFA, and ICGA imaging, had to differentiate between AMD and PCV, study the activity of AMD using Coscas’ criteria (active vs. quiescent), and categorize PCV subtypes, while examiner B had only access to OCTA. Then, the diagnostic concordance was assessed between both examiners. Results. A total of 27 patients (11 females (40.7%) and 16 males (59.3%), P = 0.231 ) were included in the analysis. Among those, 13 patients presented with neovascular AMD and 14 patients with PCV. There were 92.3% of correct answers regarding appropriate diagnosis and lesion characterization among AMD patients, against 61.5% of correct answers among PCV patients. The overall interrater reliability agreement between examiners, using Cohen’s kappa coefficient ( κ ) was 0.70 (0.5082-0.8916). Disagreement was found with one active AMD misdiagnosed as inactive AMD, three inactive PCV misdiagnosed as inactive AMD, and one inactive PCV misdiagnosed as active AMD. Conclusion. SS-OCTA alone remains limited in some specific phenotypes of PCV, which suggests the ongoing role of B-scan OCT associated with FFA and ICGA in the diagnosis of these conditions.

Periprosthetic joint infection may occur after prosthetic joint replacement. Treatment usually requires removal of the prosthesis in addition to systemic antibiotics. We report a case of enterococcal prosthetic knee infection that was treated with arthroscopic lavage and intravenous antibiotics (ampicillin 2 g every 4 h for 6 weeks and gentamicin 80 mg every 8 h for 2 weeks) with retention of the prosthesis. Upon discharge, the patient was placed on oral amoxicillin 1g twice daily for a duration of 2 years. The patient now has been off antibiotics for 3 years, and is showing no signs of recurrence of his infection on his last follow-up.
