  • Ophthalmoacromelic syndrome (OAS) [MIM:206920]: A rare disorder presenting with ocular anomalies, ranging from mild microphthalmia to true anophthalmia, and limb anomalies. Limb malformations include fused 4th and 5th metacarpals and short 5th finger in hands, and oligodactyly in foot (four toes). Most patients have bilateral anophthalmia/ microphthalmia, but unilateral abnormality is also noted. Other malformations are rare, but venous or vertebral anomaly was recognized each in single cases. {ECO:0000269 PubMed:21194678, ECO:0000269 PubMed:21194680, ECO:0000269 PubMed:21750680, ECO:0000269 PubMed:23646827}.
