The Thermal Signature of Wound Healing.

Background: Despite major efforts in prevention, surgical site infections (SSIs) remain a burden on patients and the healthcare system and are associated with significant morbidity. SSIs are one of the costliest healthcare-associated infections. The diagnosis of SSIs is based mainly on clinical assessment, which may result in a delay in detection.

Color doppler imaging of the central retinal artery in premature infants undergoing examination for retinopathy of prematurity.

Purpose: Recent attempts have been made to quantify blood flow velocity in the central retinal artery (CRA) of adults using color Doppler imaging (CDI). Although retinal vascular abnormalities are the hallmark of severe retinopathy of prematurity (ROP), normal values have not been established for CRA blood flow velocity in premature infants.

Methods: CDI of the CRA was successfully performed on 43 eyes in 22 infants (postconceptional ages 32 to 39 weeks) before the infants underwent examination for ROP.

Dimensions of the pediatric crystalline lens: implications for intraocular lenses in children.

As surgeons gain more experience with the implantation of posterior chamber intraocular lenses (IOLs) into the capsular bag in children, the minimum age for which implantation is advised may continue to be lowered. Accurate sizing of an IOL intended for in-the-bag fixation may depend on knowledge of the size of the capsular bag. In order to develop a growth curve for the normal crystalline lens and hence the capsular bag, 50 pediatric autopsy eyes ranging in age from 1 day to 16 years were obtained postmortem and measured within 24 hours after enucleation.

Can non-ophthalmologists screen for retinopathy of prematurity?

Background: Dilation and tortuosity of the posterior pole vessels ("plus disease") is a poor prognostic sign and may indicate the presence of threshold or pre-threshold retinopathy of prematurity (ROP). Because stage 3 ROP appears rarely in the absence of posterior pole vascular abnormalities, we prospectively evaluated the ability of non-ophthalmologists (4th-year medical students, pediatric residents, and nurse practitioners) to identify abnormalities in the retinal blood vessels of infants undergoing examinations for ROP.

Methods: Fifty infants weighting less than 1600 g at birth were examined between 32 and 40 weeks after conception.

Pathology of silicone intraocular lenses in human eyes obtained postmortem.

The increased use of phacoemulsification and small incision surgery has led to interest in a soft intraocular lens (IOL) for implantation after cataract extraction. We present the pathologic findings of seven eyes obtained postmortem from five patients with silicone IOLs. Length of implantation ranged from 6 weeks to 13 months.
