Purpose:
To report the clinicopathologic features of intraocular osseous production in association with proliferative vitreoretinopathy.
Method:
The clinical and histopathologic features of two patients with proliferative vitreoretinopathy and intraocular bone formation are reviewed.
Results:
Preretinal osseous tissue incorporated in the proliferative vitreoretinopathy was surgically removed in one patient, and osseous tissue was present in the proliferative vitreoretinopathy in the enucleated eye of the other patient.
Conclusions:
Bone formation, presumably from metaplastic retinal pigment epithelium, may be present in proliferative vitreoretinopathy tissue. The intraocular bone is present internal rather than external to the neurosensory retina.
