[Clinical observation and analysis in age-related macular degeneration with one eye of wet form and the other of dry form].
Twenty two cases (44 eyes) of age-related macular degeneration with one eye of wet form and the other of dry form were included in this study. The range of the lesion was determined on magnified negative film of fluorescein angiography. In the dry group 72.7% eyes had normal FAZ and in the wet group 59.1% eyes revealed the lesion involving whole FAZ. The area of the lesion was measured by polar coordinates computational method, the mean area was 5.048mm2 in the wet form and 1.034mm2 in the dry form, there was statistically significant difference between the mean areas of the two groups (P < 0.01). The mean amplitude of photopic ERG b-wave was 101.74 mu v in the wet form and 126.35 mu v in the dry form. The morphological characteristics, the abnormalities of the visual function and possible changes in the two groups of this disease were discussed.
