Comparing Year 3 against Year 1, mean Ranibizumab injection frequency was 2.1 vs 4.3; mean Ozurdex injection frequency was 0.2 vs 1.1. In Year 3, 39.6% of patients did not require any form of injections, laser frequency was also reduced to 22.9% (vs 81.8% in Year 1). There was no endophthalmitis in the cohort, one progressed to neovascular glaucoma in Year 2 and mortality rate was recorded as 6%. Conclusion Our real-world clinical practice for RVO patients using a combined therapy is associated with good long-term VA and anatomical outcomes with less intravitreal re-treatment rates. © 2020 Horner et al.Aim Tacrolimus is an immunosuppressive drug with higher potency compared to cyclosporine A (as a useful immunosuppressant). We prepared an ophthalmic solution formulation of Tacrolimus using hydroxypropyl beta cyclodextrin (HP-ßCD). In the present study, safety of this formulation was investigated in rabbits. Materials and Methods Formulation containing HP-ßCD, Tacrolimus, Polyvinyl alcohol (PVA) and Benzalkonium Chloride in PBS 7.4 was prepared. Tacrolimus concentration in ophthalmic preparation was 0.05% w/v. Ten male New Zealand white rabbits were housed in clean separated cages. One drop of Tacrolimus prepared formulation and a placebo formulation were applied every 12 hrs in the right and left eyes respectively, for 28 days. Results This new aqueous formulation of Tacrolimus could improve Tacrolimus solubility about 42 times. Clinical examinations on the 1st, 3rd, 7th, 14th and 28th days of study showed transient redness and conjunctivitis in some cases of both control and intervention groups that was not persistent. At the end of the study, there were no statistical differences between the two groups in corneal epithelial defect, redness or pathological evaluations. Conclusion The results of this study suggest that eye drop formulation of CD-Tacrolimus is safe in preli
