Senile scleral plaques and senile scleromalacia.

A case of senile scleral plaques is reported in which expulsion of a calcified plaque anterior to the insertion of the medial horizontal rectus muscle gave rise to senile scleromalacia. Histopathological examination revealed a second calcified plaque at the site of the contralateral senile scleral plaque in this eye. This case indicates that senile scleromalacia is a scleral disease sui generis which occurs by expulsion of a calcified plaque in advanced cases of senile scleral plaques. Senile scleromalacia has not previously been described as a clinical entity.
