    Abstract:

    AIM: To investigate whether pretreatment with pressure-lowering medication prior to anti-vascular endothelial factor (VEGF) injections had an effect on glaucomatous progression in patients with preexisting glaucoma or ocular hypertension (OHT). METHODS: A total of 66 eyes from 54 patients with a preexisting diagnosis of glaucoma or OHT, treated with six or more anti-VEGF injections were selected for chart review. Primary outcome measures were rate of visual field loss in dB/year, rate of change in retinal nerve fiber layer (RNFL) thickness in microns/year, and need for additional glaucoma intervention. RESULTS: The number of eyes requiring additional glaucoma medication was 5 of 20 (25.0%) and 14 of 46 (30.4%) for the pretreated and non-pretreated groups, respectively. The number of eyes requiring glaucoma laser or surgery was 4 of 20 (20.0%) and 13 of 46 (28.3%) for the pretreated and non-pretreated groups, respectively. Estimated mean rate of pattern standard deviation decline was not significant in either group (P>0.073), with no difference between groups (P=0.332). Although both groups showed significant RNFL change from baseline (P<0.011), no difference was detected between groups (P=0.467). CONCLUSION: Pretreatment has no detectable effect on structural or functional glaucomatous progression. Patients receiving repeated injections may be at risk for glaucomatous complications requiring invasive intervention.
