Gum inflammation may be linked to eye disease
A novel study may have uncovered an association between periodontal disease and later ophthalmologic diseases.
In a retrospective study presented as an abstract at the 2026 Association for Research in Vision and Ophthalmology Annual Meeting, investigators used the TriNetX database to examine the ophthalmologic outcomes of more than 25,000 patients with or without periodontal disease who visited an ophthalmologist. The participants in the periodontal disease group had seen an ophthalmologist within one year of their diagnosis.
Compared with those who didn’t have periodontal disease, the patients with periodontal disease were more likely to experience a range of ophthalmologic conditions within 10 years of diagnosis — including conjunctivitis, blepharitis, dry eye syndrome, corneal ulcers, iridocyclitis, chorioretinal inflammation, retinal artery occlusion, nonexudative age-related macular degeneration, cystoid macular degeneration, retinal hemorrhage, glaucoma suspect, open-angle glaucoma, angle-closure glaucoma, optic atrophy and cataracts.
The investigators emphasized that the potential link between periodontal disease and the development of inflammatory and degenerative ophthalmologic diseases could necessitate greater multidisciplinary collaboration between dental professionals and ophthalmologists to provide earlier preventive treatment. The findings built on recent evidence connecting poor oral health to systemic inflammation, underscoring the critical need for good oral hygiene habits and regular dental visits. Further studies could elucidate the ocular benefit of receipt of periodontal therapy.
