Age-related macular degeneration and optic disk morphology.
OBJECTIVE
To assess the relationship between age-related macular degeneration and appearance of the optic disk.


METHODS
By morphometric evaluation of wide-angle color fundus photographs, 143 patients with age-related macular degeneration were compared with 33 normal subjects and with 83 diabetic patients.


RESULTS
Size and shape of the optic disk and size of parapapillary atrophy did not vary significantly (P > .12) between the study groups.


CONCLUSIONS
Age-related macular degeneration is not associated with special features in the appearance of the optic disk. Parapapillary atrophy, large or small optic disk, and abnormal disk shape are neither risk factors nor protective factors of age-related macular degeneration.
