The association of a range of ocular anomalies (anophthalmia, microphthalmia and retinal abnormalities) with variable developmental delay and central nervous system malformations. Less than 20 cases have been reported in the literature so far. The clinical picture is highly variable, even between affected members of the same family. Severe developmental delay was noted in some patients, whilst others showed normal cognitive development. Pituitary dysfunction, leading to growth hormone deficiency and short stature, or combined pituitary hormone deficiency, has also been reported. The syndrome is caused by heterozygous mutations in the OTX2 gene (14q22.3).
