Ocular Blood Flow in Preterm Neonates: A Preliminary Report.

Purpose: Retinopathy of prematurity (ROP) is a vision-threatening complication occurring in pre-term neonates. The standard of care entails regular monitoring by dilated ophthalmoscopy examinations, which entail stress and potential morbidity. In this pilot study, we used plane-wave ultrasound (PWUS) to image, measure, and assess the association of blood-flow velocities in the retrobulbar vessels with ROP stages ranging from stage 0 (immature vessels without ROP) to stage 3.

Bacterial contamination of ophthalmic solutions used in an extended care facility.

Aim: To assess the frequency of contamination of ophthalmic solutions in a long-term care facility and to describe the characteristics of contaminated solutions.

Methods: One hundred and twenty-three ophthalmic solutions used for patient treatment in a long-term care facility were cultured for bacteria. The culture results were analysed according to the therapeutic class of the solution, how long the bottle had been in use and the appearance of the bottle on visual inspection.

Comparison of ultrasonic and ophthalmoscopic evaluation of retinopathy of prematurity.

Purpose: Screening for detection of retinopathy of prematurity (ROP) currently is limited to indirect ophthalmoscopy, which requires considerable examiner skill and experience. We investigated whether conventional 10 MHz B-scan ultrasonography could document the clinical stages of ROP as accurately as indirect ophthalmoscopy.

Methods: Thirty-four eyes of 18 neonates were examined by masked, independent observers with indirect ophthalmoscopy and digitally recorded 10-MHz B-scan ultrasonography.

Bilateral persistent fetal vasculature associated with holoprosencephaly.

A 3.26-kg neonate with a gestational age of 40 weeks presented with episodic hypothermia and seizures, but stable vital signs. Semilobar holoprosencephaly was seen on magnetic resonance imaging.
