†Data for BRAVO, BRIGHTER, COMRADE-B is reported after patient-level data analysis.
‡Central foveal thickness.
§In GENEVA,14 baseline characteristics were not split between patients with CRVO and those with BRVO. BCVA letters gained from the NICE assessment file entitled ‘Evidence review: dexamethasone implants (Ozurdex) for macular oedema after retinal vein occlusion (2010)’. SE of the mean was graphically estimated.
2q4, 2 mg monthly; BCVA, best-corrected visual acuity (assessed in terms of Early Treatment Diabetic Retinopathy Study letters); BRVO, branch retinal vein occlusion; CRT, central retinal thickness; CRVO, central retinal vein occlusion; NA, not applicable; NICE, National Institute for Health and Care Excellence; PRN, pro re nata (as needed); RCT, randomised controlled trial.
