Some insurance companies mandate a form of step therapy, which involves initial use of an inexpensive drug, bevacizumab, to treat diabetic macular edema. This trial compared two treatments: step therapy and use of a more expensive drug.

PURPOSE: To describe the Port Delivery System with ranibizumab refill-exchange procedure. METHODS: Procedure based on the clinical trial program in patients with retinal diseases. RESULTS: The refill-exchange procedure is performed under topical anesthesia and strict aseptic conditions. Supplemental task lighting and magnification are recommended throughout the procedure. Ranibizumab is aseptically transferred from the vial with the filter needle and air is removed from the syringe. The filter needle is then replaced with the refill needle; any remaining air is removed from the syringe and the plunger is advanced to the 0.1-mL mark. Targeting the implant septum center, the refill needle is inserted perpendicularly to the globe until the soft stop contacts the conjunctiva (perpendicular orientation and conjunctival contact are maintained throughout the procedure); a cotton-tipped applicator is recommended for globe stabilization. The entire syringe contents are slowly injected over 5–10 seconds while existing solution fills the fluid collection reservoir. Once completed, the needle is carefully withdrawn while maintaining perpendicularity. The procedure can be successfully performed in rare, specific cases, including subconjunctival thickening or fibrous capsule formation, fluid-filled bleb formation, and corneal patch grafts. CONCLUSION: The procedure is straightforward but distinct from intravitreal injections and requires adherence to standardized techniques. With appropriate preparation, the procedure can be performed in specific cases. [Ophthalmic Surg Lasers Imaging Retina. 2022;53:257–265.]

Silicone oil is a commonly used tamponade agent. We report the rare complication of a patient who presented with silicone oil in the suprachoroidal space following retinal detachment repair. The silicone oil was subsequently removed without any long-term complications. [ Ophthalmic Surg Lasers Imaging Retina. 2013;44:284–286.]

Objective To evaluate the safety and efficacy of BI 1467335 in patients with non-proliferative diabetic retinopathy (NPDR). Methods ROBIN is a Phase IIa, double-masked, randomised, placebo-controlled study (NCT03238963). Patients with NPDR and without centre-involved diabetic macular oedema were included; all had a best corrected visual acuity letter score of ≥70 Early Treatment Diabetic Retinopathy Study letters in the study eye at screening. Patients received oral BI 1467335 10 mg or placebo once daily for 12 weeks. Post-treatment follow-up was 12 weeks. The primary endpoint was the proportion of patients over the 24 weeks with ocular adverse events (AEs). Secondary endpoints were the proportion of patients with ≥2-step improvement from baseline in DRSS severity level at Week 12 and the proportion of patients with non-ocular AEs at 24 weeks. Results Seventy-nine patients entered the study (BI 1467335, n  = 40; placebo, n  = 39). The proportion of patients with ocular AEs over 24 weeks was greater in the BI 1467335 versus the placebo group (35.0% vs 23.1%, respectively). Treatment-related AEs were reported for similar numbers of patients in the placebo and BI 1467335 group (7.7% vs 7.5%, respectively). At Week 12, 5.7% ( n  = 2) of patients in the BI 1467335 group had a 2-step improvement in DRSS severity level from baseline, compared with 0% in the placebo group. Conclusions BI 1467335 was well tolerated by patients with NPDR. There was a high variability in DRSS levels for individual patients over time, with no clear efficacy signal.
