Half of regressed polypoidal choroidal vasculopathy recurs within two years of stopping injections
A Thai prospective study tests as-needed aflibercept after complete polyp regression; the organism predicts the course of endogenous endophthalmitis, with Serratia most likely to cost the eye; and switching biologic class may beat a second anti-TNF in refractory uveitis.
The edition in brief
Four items for ophthalmologists. In 81 treatment-naive eyes with polypoidal choroidal vasculopathy given aflibercept, 40% achieved complete polypoidal regression; of 26 regressed eyes then treated as needed, half recurred within two years, and recurrences cost a median 3.5 letters, with 21% losing 10 or more and 36% developing new haemorrhage. In 305 eyes with culture-positive endogenous endophthalmitis at nine US centres, S. aureus was the commonest organism, blood cultures were positive in 66% but vitreous in only 31%, presenting acuity was the strongest predictor of final vision, and enucleation was highest with gram-negative infection (27.7%), especially Serratia. A meta-analysis of 466 patients with anti-TNF-refractory non-infectious uveitis found 83% responded after a biologic switch, with interclass switching favoured over intraclass (85% vs 71% in sensitivity analysis). The FDA recorded a supplement to Samsung Bioepis's ranibizumab biosimilar Byooviz. The pearl covers the systemic workup for endogenous endophthalmitis.
Endogenous endophthalmitis: the organism shapes the course, and Serratia costs eyes
Take blood cultures early, treat broadly while eye cultures are pending, and warn patients with gram-negative infection about the risk to the eye.
Refractory non-infectious uveitis: switching biologic class may work better than switching anti-TNF
When non-infectious uveitis fails an anti-TNF, a switch of biologic class is a reasonable next step.
FDA records a supplement to the ranibizumab biosimilar Byooviz
No change to anti-VEGF practice; this is a licence supplement for a ranibizumab biosimilar.
Endogenous endophthalmitis is a systemic infection with an eye sign
Treat endogenous endophthalmitis as sepsis until proved otherwise and find the source.
After complete polyp regression in PCV, half of eyes recur on as-needed aflibercept
After complete polyp regression, keep close OCT monitoring or continue proactive treatment; half of eyes recur.
