The present study was designed as a cross-sectional survey to assess the association between soft drusen and ‘choroidal fill ing defects'. Sixty-eight eyes presenting hard drusen and 58 eyes with soft drusen of 126 subjects with an age range of 45-83 years were examined in the present study. Choroidal filling defects were present in 13 out of 68 (19.1%) patients with hard drusen and 29 out of 58 (50%) with soft drusen (-/: square = 13.4: p 75 years. For this analysis, we used the MantelHaenszel test.

Choroidal filling defects, identified ac cording to the angiographic characteristics, were present in 13 out of 68 (19.1%) patients with hard drusen and 29 out of 58 (50%) with soft drusen. A definite association between choroidal filling defects and soft drusen was found. The x: value was 13.4 with an associ ated p value
