PG - 767-774 LID - 10.1111/ceo.13763 [doi] AB - IMPORTANCE: Long-term data are needed regarding effective and safe glaucoma treatment modalities. BACKGROUND: This study evaluated 4-year outcomes of second-generation trabecular micro-bypass stent implantation (iStent inject) combined with topical travoprost in open-angle glaucoma (OAG). DESIGN: Prospective, non-randomized, multi-surgeon study at a tertiary care ophthalmology centre. PARTICIPANTS: OAG subjects with preoperative intraocular pressure (IOP) 18 to 30 mmHg on two medications and 22 to 38 mmHg post-washout. METHODS: Subjects (n = 53) underwent standalone iStent inject implantation and started travoprost on postoperative Day 1. Measures included IOP, medications, comprehensive ophthalmic examinations and testing, and adverse events (AEs). Annual medication washouts were performed. MAIN OUTCOME MEASURES: Mean medicated and unmedicated IOP; and proportions of eyes with IOP /=20% reduced while on travoprost vs screening IOP on two medications. RESULTS: At 48 months postoperative, 85% of eyes reduced IOP >/=20% on travoprost vs screening IOP on 2 medications; 92% of eyes had IOP /=20% vs preoperative washout IOP. Throughout follow-up, mean IOP on travoprost was 11.9 to 13.0 mmHg (34%-40% reduced vs 19.7 mmHg on 2 medications preoperatively; P < .0001 throughout), and post-washout IOP was 16.5 to 17.7 mmHg (28%-34% reduced vs 24.9 mmHg preoperatively; P < .0001 throughout). Favourable safety included minimal AEs; stable visual acuity, cup-to-disc ratio and visual fields; and no secondary surgeries. CONCLUSIONS AND RELEVANCE: Combining iStent inject implantation with topical prostaglandin produced significant and safe 4-year IOP and medication reductions in OAG.
