Study suggests link between macular pigment optical density and glaucoma

Macular pigment optical density was markedly lower in patients with glaucoma than in healthy controls, according to a study.The study included 40 patients with open-angle glaucoma and 54 healthy individuals without ocular disease. Mean age was 69 years in the glaucoma group and 66 years in the control group.Investigators examined biomicroscopy, fundoscopy, Goldmann tonometry and visual fields and collected data on age, gender, smoking history, presence of glare and years diagnosed with glaucoma. Heterochromatic flicker photometry was used to gauge macular pigment optical density at 0.5° of retinal eccentricity.
