Purpose: Peters anomaly is a rare dramatic finding at birth and can be associated with other systemic malformations. We performed a literature review of multiple case reports and case series to better define the common characteristics and unusual findings associated with Peters anomaly.

Methods: A representative case is discussed followed by a literature review of multiple case reports and case series. The literature search was conducted for the years 1969 to 2009. Cases and case series were included in the review of published English ophthalmic literature. Cases were excluded if no information was reported on ocular and systemic malformations or if no information was reported on surgical interventions or outcomes. In addition, if cases did not report laterality of the lesion, they were excluded from the review. Fifty-eight cases were found that fit the above criteria, and the relevant cases were reviewed to better characterize the systemic malformations, interventions, and outcomes associated with Peters anomaly reported in the literature.

Results: Fifty-eight cases of Peters anomaly were reviewed. Of those cases reporting sex, 56% were men and 44% of cases were women. In terms of laterality, 67.2% of cases were bilateral versus 32.8% of cases that were unilateral. Moreover, bilateral cases of Peters anomaly were associated with a higher rate of systemic malformations (71.8%) versus unilateral Peters anomaly (36.8%). This difference was significant (P < 0.03 by Fischer exact test). In the 15 eyes where results of penetrating keratoplasty were reported, the overall success rate was 53%. However, the success rate was significantly higher in patients with Peters anomaly type I (87.5%), as opposed to those patients with Peters anomaly type II (14.2%) (P < 0.02 by Fischer exact test).

Discussion: The clinical features, epidemiology, genetics, complications, and treatments of Peters anomaly are presented. Cornea specialists who care for pediatric patients should be aware of the common and uncommon associations with Peters anomaly. Although bilateral Peters anomaly is much more commonly associated with systemic malformations, we believe that all patients with Peters anomaly should be screened for systemic malformations by both pediatricians and geneticists and undergo chromosomal analysis and molecular genetic testing.
