The Royal College of Paediatrics and Child Health Retinopathy of Prematurity Screening Guidelines (2022): a series of treated infants falling outside the updated criteria.

Background/objectives: Screening for retinopathy of prematurity (ROP) is a core healthcare intervention in premature babies to avoid preventable sight loss. A variety of screening criteria are in place globally for this purpose. The Royal College of Paediatrics and Child Health recently updated the United Kingdom ROP screening guidelines (March 2022).

Central nervous system gadolinium accumulation in patients undergoing periodical contrast MRI screening for hereditary tumor syndromes.

Background: Patients with hereditary tumor syndromes undergo periodical magnetic resonance imaging (MRI) screening with Gadolinium contrast. Gadolinium accumulation has recently been described in the central nervous system after repeated administrations. The prevalence and rate of accumulation in different subgroups of patients are unknown.

Cortical Visual Connections via the Corpus Callosum are Asymmetrical in Human Infantile Esotropia.

Purpose: Besides chiasmal hemidecussation, interhemispheric connections are likely important in human binocularity. The corpus callosum (CC) is the major fiber bundle in the mammalian brain which mostly connects homologous cortical areas in the two hemispheres. Visual interhemispheric connections were found abnormal in strabismic cats.

Interhemispheric Connections between the Primary Visual Cortical Areas via the Anterior Commissure in Human Callosal Agenesis.

In humans, images in the median plane of the head either fall on both nasal hemi-retinas or on both temporal hemi-retinas. Interhemispheric connections allow cortical cells to have receptive fields on opposite sides. The major interhemispheric connection, the corpus callosum, is implicated in central stereopsis and disparity detection in front of the fixation plane.
