Abstract:
Introduction: Anti-vascular endothelial growth factors (anti-VEGF) intravitreal injection is one of the popular procedures for medical retina diseases. However, the incidence of angle-closure post intravitreal injection was reported.
Several similar studies were conducted previously, but the results were inconsistent and mostly focused on bevacizumab. Methods: A prospective cohort study was conducted. After informed consent, patients who were more
than 17 years old and received the first intravitreal anti-VEGF injections (ranibizumab or aflibercept) were recruited.
Exclusion criteria included patients with underlying glaucoma, ocular hypertension, intumescence cataract, high
refractive error or those with history of intraocular operation or ocular trauma. Pre- and post-injection’s intraocular
pressure (IOP) and ocular biometry included “central anterior chamber depth” (CACD), “angle opening distance”
(AOD500), and “trabeculo-iris angle” (TIA500) at nasal and temporal 500 µm away the scleral spur were acquired
and analyzed. Results: 72 eyes from 66 patients were studied. Mean (SD) increment of IOP following injection within 30 minutes and 1 hour were 6.16 (0.68) mmHg (p<0.001) and 1.26 (0.35) mmHg (p=0.002) respectively. Mean
(SD) differences of temporal TIA500 between pre with within 30 minutes and 1-hour post-injection were 1.66 (0.66)
degrees (p=0.04) and 1.45 (0.57) degrees (p=0.04) respectively. No significant relationship between the changes of
IOP and ocular biometry was found. Conclusion: A single dose of anti-VEGF in a normal population is relatively safe.
However, concern on the risk of glaucoma progression and acute angle-closure still needs to be addressed. Further
studies on at-risk populations and repeated injections are useful.
