A comparison cohort without periodontitis was selected and matched 1:1 using propensity scores for sex, age, index year, and Charlson Comorbidity Index. Each group included 167,530 individuals. The periodontitis cohort was further divided into treated and untreated subgroups according to periodontal treatment codes (\n                      <jats:italic>n\u00a0=<\/jats:italic>\n                      \u00a068,705 and 98,825, respectively).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      During follow\u2010up, ERD occurred in 0.26% (\n                      <jats:italic>n\u00a0=<\/jats:italic>\n                      \u00a0437) of patients with periodontitis and 0.06% (\n                      <jats:italic>n\u00a0=<\/jats:italic>\n                      \u00a0100) of those comparison individuals.

In this large study using national health data from Taiwan, we examined whether people with gum disease are more likely to develop exudative retinal detachment, a serious eye condition in which fluid builds up under the retina and can impair vision. By comparing 167,530 patients with gum disease with an equal number without it, matched for age, sex, and general health, we found that this eye condition occurred much more frequently among those with gum disease. Even after accounting for other medical conditions, individuals with periodontitis were more than three times as likely to experience this form of retinal detachment. This pattern was consistent regardless of whether patients had received specific gum treatments. These results suggest that chronic inflammation from gum disease may be connected to eye disorders, emphasizing that maintaining good oral health could play an important role in preserving vision and overall health.<\/jats:p>\n
