Abstract
AIM
To evaluate the safety of 1.25mg and 2mg intravitreal ziv-aflibercept (IVZ) in Ghanaian eyes with choroido-retinal vascular diseases.
DESIGN
Prospective, randomised, double blind, interventional study.
METHODS
Twenty patients with centre involving macular oedema in diabetic retinopathy, retinal vein occlusion, and neovascular age-related macular degeneration were assigned to 2 groups receiving 3 doses of 1.25mg/0.05ml (group 1) and 2mg/0.08ml IVZ (Group 2) at 4 weekly intervals. Safety data was collected after 30 minutes, 1 and 7 days, and 4, 8 and 12 weeks after injection. Changes in continuous variables were compared using paired t-test and categorical variables were compared using chi-square test of proportions. Repeated-Measures ANOVA with nesting test was used to compare variations in continuous variables by IVZ dose over time. Primary outcome measures were ocular and systemic adverse events at 4 weeks.
RESULTS
Eleven females and nine males, with mean age of 63.2± 7.3 years were included. Ocular adverse events included subconjunctival haemorrhage in 1 eye, intraocular pressure (IOP) >21mmHg at 30 minutes in 6 eyes and mild pain in 3 eyes at 1-day. There was no significant difference in IOP rise between the 2 groups at 30 minutes (p = 0.21). No other ocular or systemic adverse events were observed. There was significant improvement in the best corrected visual acuity (LogMAR) from 0.95±0.6 to 0.6±0.4 (p<0.01) and 0.47±0.3 (p<0.01), reduction in central subfield foveal thickness from 405.9±140 um at baseline to 255.6±75 um (p<0.01) and 238±88 um (p<0.01) at 4 and 12 weeks respectively, although no difference was observed between the 2 groups (p = 0.34).
CONCLUSION
IVZ at 1.25mg and 2mg had similar safety profiles, and did not have any major unexpected adverse events. Further studies with larger cohorts are required to confirm efficacy.
