Intravitreal bevacizumab for the treatment of retinal angiomatous proliferation

PURPOSE: To verify the potential efficacy of intravitreal bevacizumab (IVB) injections for the treatment of retinal angiomatous proliferation (RAP). DESIGN: Retrospective interventional case series. METHODS: Four consecutive patients affected by RAP at different stages and refractory to photodynamic therapy (PDT). All patients underwent a complete ophthalmic examination including best-corrected visual acuity (BCVA), fluorescein and indocyanine green angiographies, and optical coherence tomography(OCT) at baseline, and after one, three, six, nine, and 12 months. All patients received IVB injections (1.25 mg/0.05 ml). RESULTS: The best functional response has been achieved in patients with RAP at stages I and 2; whereas in stage 3, a detectable recovery of visual acuity was not observed. This improvement was stable over the follow,up period with a concomitant reduction of macular thickness. CONCLUSIONS: The use of IVB in patients affected by RAP seems to exert morphologic benefits at all RAP stages that does not always correspond a functional improvement

Effect of COVID-19-related lockdown on ophthalmic practice in Italy: A report from 39 institutional centers

BACKGROUND/OBJECTIVES: To compare the number of eye surgical procedures performed in Italy in the 2months following the beginning of lockdown (study period) because of COVID-19 epidemic with those performed in the two earlier months of the same year (intra-year control) and in the period of 2019 corresponding to the lockdown (inter-year control).METHODS: Retrospective analysis of surgical procedures carried out at 39 Academic hospitals. A distinction was made between elective and urgent procedures. Intravitreal injections were also considered. Percentages for all surgical procedures and incidence rate ratios (IRR) for rhegmatogenous retinal detachment (RRD) events were calculated. A p value <0.05 was considered significant.RESULTS: A total of 20,886 versus 55,259 and 56,640 patients underwent surgery during the lockdown versus intra-and inter-year control periods, respectively. During the lockdown, only 70% of patients for whom an operation/intravitreal injection was recommended, finally underwent surgery; the remaining patients did not attend because afraid of getting infected at the hospital (23%), taking public transportation (6.5%), or unavailable swabs (0.5%). Elective surgeries were reduced by 96.2% and 96.4%, urgent surgeries by 49.7% and 50.2%, and intravitreal injections by 48.5% and 48.6% in the lockdown period in comparison to intra-year and inter-year control periods, respectively. IRRs for RRDs during lockdown dropped significantly in comparison with intra- and inter-year control periods (CI: 0.65-0.80 and 0.61-0.75, respectively, p<0.001 for both).CONCLUSION: This study provides a quantitative analysis of the reduction of eye surgical procedures performed in Italy because of the COVID-19 epidemic
