{"doi":"10.2147/opth.s386033","title":"Glaucoma Drainage Device Erosions in Patients Receiving Anti-Vascular Endothelial Growth Factor Therapy for Diabetic Retinopathy","abstract":"Purpose: To determine if intravitreal anti-vascular endothelial growth factor (anti-VEGF) injections are associated with an increased risk of glaucoma drainage device (GDD) erosions. Patients and Methods: A retrospective chart review was conducted including patients with diabetic retinopathy and had a GDD implanted at a large academic institution. The rate of GDD erosions was compared between eyes that did or did not receive intravitreal anti-VEGF injections. A subanalysis was also performed the relationship between diabetic macular edema (DME) and intravitreal steroid injections and GDD erosions. Results: A total of 677 eyes from 608 patients was included. A total of 447 eyes received at least one anti-VEGF injection; 230 eyes never received such therapy. Twenty eyes (4.5%) receiving anti-VEGF had at least one erosion event, compared to 7 eyes (3.0%) of patients not receiving anti-VEGF therapy (OR 1.49, p=0.37). Diabetic macular edema was associated with a significantly increased rate of erosion in eyes not receiving anti-VEGF (71.4% versus 31.4%, p=0.034), but not in eyes receiving anti-VEGF (30.0% versus 40.7%, p=0.34). Receiving more than one specific anti-VEGF agent, an increased frequency or total number of anti-VEGF injections, or receiving intravitreal steroids were not associated with an increased risk of erosion (p>0.05). Conclusion: In patients with diabetic retinopathy, the use of anti-VEGF does not result in an increased rate of GDD erosions or recurrent erosions. Further research is needed over a longer follow-up period to determine if longer or more frequent anti-VEGF treatment is a risk factor for recurrent erosions.","journal":"Clinical ophthalmology","year":2022,"id":296043,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":1,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9601,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2022-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":323001,"name":"Elizabeth A.
