Abbreviations: AMD, age-related macular degeneration; CT, choroidal thickness; inf 500, inferior point of measurement 500 μm from fovea, and so on till 2500 μm; PCV, polypoidal choroidal vasculopathy; sup, superior; temp, temporal.
*P value could not be calculated, as the number of eyes in the fellow AMD group was less and statistical comparison could not be done with the normal subjects.
