[Frequency and clinical presentation of congenital ocular anomalies in Asturias 1990-2004].
BACKGROUND
Congenital ocular anomalies (COAs) can produce serious disability.


OBJECTIVE
The purpose of this investigation was to assess the prevalence of COAs, their trends and to describe the associated malformations and syndromes in a geographically defined population.


METHODS
Data from the Asturias Registry of Congenital Defects were used. The period studied was from 1990 to 2004 and the study population the 103,452 births of mothers living in the region. Total prevalence was calculated.


RESULTS
A total of 3035 cases with congenital defects were recorded, of these 70 had COAs. The total prevalence was 6.8 per 10000 births, with a stable trend during this period. The most common COAs were: congenital cataract (2.0 per 10000 births), anophthalmos/microphthalmos (1.4 per 10000 births) and coloboma (1.3 per 10000 births). 40% of COAs occurred as isolated defects, 37% were syndromes and 23% were associated with other congenital defects.


CONCLUSIONS
The prevalence of COAs in Asturias over this period had a stable trend and the congenital cataract was the commonest COAs. COAs, particularly the anophthalmos/microphthalmos were associated with other congenital anomalies.
