Microhemorrhagic maculopathy
R. C. Pruett, A. C. Carvalho and C. L. Trempe
Twenty subjects, 12 males and eight females aged 14 to 58 years, had a
small monocular macular hemorrhage that was punctate, round, or bilobed and
seemed to originate from the perifoveal capillary plexus. Although clinical
study results failed to establish a common causal denominator, three of the
20 patients had a history of preceding increased venous pressure (Valsalva
stress), three of nine subjects tested showed impaired blood platelet
aggregation, and an additional four of 20 were taking medications known to
impair platelet function both in vitro and in vivo. Macular
microhemorrhages resolve spontaneously, and available data suggest that the
syndrome is benign.
