Azithromycin 1.5% for 3 days was as effective and as safe as tobramycin for 7 days. Furthermore, more azithromycin than tobramycin patients presented an early clinical cure at Day 3. Due to its twice daily dosing regimen for 3 days, azithromycin represents a step forward in the management of purulent bacterial conjunctivitis, especially in children.

Primary congenital glaucoma (PCG) is a heterogeneous autosomal recessive disorder caused by unknown developmental defect(s) of the anterior chamber of the eye. A member of the cytochrome P450 gene family, CYP1B1, was found to be mutated in PCG patients in different populations, albeit to a variable extent. In this study, CYP1B1 mutations were searched for in 32 unrelated PCG patients from Morocco. Two mutations were detected in 11 (34%) patients. One, 4339delG, is novel and causes a frameshift at residue 179. The other, G61E, was previously found in patients from Turkey and Saudi Arabia. Seven patients were homozygous for 4339delG and two other patients for G61E, whereas the two remaining patients were compound heterozygotes. The close association of 4339delG with a rare allele of D2S177, a microsatellite marker located 270 kb upstream of CYP1B1, strongly suggested a founder effect for 4339delG. The occurrence of this mutation was tentatively dated at between 900 and 1700 years ago. Typing 4339delG and G61E mutations should help to prevent blindness resulting from a delayed diagnosis of PCG in Morocco.
