Abstract
To evaluate the utility of dissolvable collagen punctal plugs (CPP) in reducing ocular surface irritation after intravitreal injections (IVI). Sixty-four subjects in the experimental group received CPP after intravitreal injections. Sixty-two controls did not receive CPP. Reductions in the Ocular Surface Disease Index© (OSDI) and Standardized Patient Evaluation of Eye Dryness II (SPEED II) scores were analysed. Dry eye symptoms, as measured by reductions from the pre- to post-injection OSDI (p = 0.137) and SPEED II (p = 0.381) scores, did not significantly differ between the two groups. In sub-group analysis, patients with objective findings of dry eyes had significant improvement in their symptoms (p = 0.046) with CPP. The effect of CPP is not significant in those without dry eyes (p = 0.27). CPPs were not effective in reducing post-injection ocular irritation in patients with no or only mild dry eye symptoms. CPPs improved patients' post-injection comfort levels in those who had moderate-to-severe symptoms and objective findings of dry eye. Though costly CPP could be considered in selective patients. A standardized eye rinse could be a simple, efficacious, and cost-effective way to reduce post-injection ocular irritation; however, more studies are needed.
