Abstract:
Peters' anomaly is characterized by a central corneal opacity with corresponding defects in the posterior stroma, Descemet's membrane, and endothelium. We present 2 cases that showed corneal opacity when examined by topical endoscopic imaging (TEI). Case 1 was a 20-day-old neonatal female who had a central corneal opacity in the left eye. TEI showed that the iris stroma was adhered toward the back of the opacified cornea. Case 2 was a 4-month-old male who had a bilateral corneal opacity. TEI revealed that both a keratolenticular adhesion and a surrounding iridocorneal adhesion were observed behind the area of corneal opacity. The patient was diagnosed as having Peters' anomaly with persistent fetal vasculature. This study demonstrates that TEI is a novel method capable of looking into an eye from only a small area of the clear cornea.
