Eye scan showdown: faricimab vs ranibizumab in diabetic retinopathy

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Adults aged ≥18 years * Diabetic retinopathy with or without central macular edema * Indication for intravitreal anti-VEGF therapy according to current clinical guidelines * Ability to provide written informed consent Exclusion Criteria: * Intravitreal anti-VEGF or corticosteroid treatment in the study eye within 5 months prior to enrollment * Any intraocular surgery (including cataract surgery) 3 months prior intraocular surgery to enrollment * Retinal laser photocoagulation in the study eye within 3 months prior to enrollment * Presence of other ocular, retinal or macular diseases that may affect OCT/OCTA findings or visual acuity (e.g., age-related macular degeneration, retinal vascular occlusions) * Retinal detachment, preretinal fibrosis, vitreomacular traction * Significant media opacities (e.g., dense cataract, vitreous hemorrhage) precluding reliable OCT/OCTA imaging * Uncontrolled glaucoma (intraocular pressure \> 30 mmHg in study eye) * Active ocular inflammation * Suspected active ocular infection in either eye * Any febrile illness within 1 week prior to first injection * History or presence of any clinically significant disease, non-diabetic metabolic disorder, abnormal physical examination finding, or laboratory abnormality that, in the opinion of the investigator, may contraindicate treatment with faricimab or biosimilar ranibizumab, interfere with the interpretation of study results, or place the participant at increased risk of treatment-related complications. * Women who are pregnant, breastfeeding, or planning pregnancy within the next 100 weeks * Known hypersensitivity to faricimab or biosimilar ranibizumab or any of its excipients * Participation in another clinical trial that may affect study outcomes * Inability to comply with study procedures or follow-up
