[Association between age-related macular degeneration and periodontal disease].

Purpose: To evaluate the association between age-related macular degeneration (AMD) and periodontal disease, two frequent conditions in the elderly, with some risk factors in common.

Methods: Single center, pilot, case-control study performed in a center specialized in the diagnosis and management of AMD. Periodontal status was evaluated in 43 AMD patients and 19 controls. Fundus examination and a complete periodontal examination were performed in all subjects.

Results: AMD patients have a greater percentage of 3-4mm clinical attachment loss compared to controls (47% vs. 38%, [P=0.039]). However, no significant difference was found between the groups with regard to the prevalence of severe periodontitis.

Conclusions: These results suggest an association between AMD and attachment loss characteristic of periodontal disease and support the need for larger prospective studies to elucidate the relationships between these 2 highly prevalent and potentially severe diseases.
