Ocular Inflammatory Events Following COVID-19 Vaccination in the Paediatric Population: A Multinational Case Series.

Background: Ocular inflammatory events following COVID-19 vaccination have been reported in the adult population.

Methods: Multinational case series of patients under the age of 18 diagnosed with ocular inflammatory events within 28 days of COVID-19 vaccination.

Results: Twenty individuals were included.

The Role of Vitamin A in Retinal Diseases.

Vitamin A is an essential fat-soluble vitamin that occurs in various chemical forms. It is essential for several physiological processes. Either hyper- or hypovitaminosis can be harmful.

Perinatal risk factors associated with central retinal changes in former preterm children on optical coherence tomography angiography.

Purpose: To assess the association between perinatal risk factors for retinopathy of prematurity (ROP) and central retinal structures of former preterm children seen on optical coherence tomography angiography (OCTA).

Methods: This prospective cohort study included 40 children with a history of preterm birth and 33 healthy full-term children. We documented their birth weight, gestational age, other significant risk factors for ROP development and presence of ROP.

DISRUPTION OF THE OUTER SEGMENTS OF THE PHOTORECEPTORS ON OPTICAL COHERENCE TOMOGRAPHY AS A FEATURE OF VITAMIN A DEFICIENCY.

Purpose: To describe the optical coherence tomography features of vitamin A deficiency.

Methods: Case series includes three male patients aged 50 to 66 years with vitamin A deficiency and visual symptoms ranging from 2 to 8 months. Examination included optical coherence tomography (OCT), fundus autofluorescence imaging, full-field electroretinography6 and laboratory work-up.

Electrophysiological and SD-OCT findings in patients receiving chloroquine therapy in relation to cumulative dosage and duration of treatment.

Purpose: Assessment of multifocal ERG (mfERG) changes in patients treated with chloroquine and their correlation with morphological abnormalities, detected by spectral-domain optical coherence tomography in relation to cumulative dosage.

Methods: Data from 37 eyes of 20 patients were retrospectively collected, and one randomly selected eye per patient was considered for statistical analysis. Eyes were divided into three groups according to mfERG and visual acuity findings: normal, early and advanced maculopathy.

Choroidal structural changes in preterm children with and without retinopathy of prematurity.

Purpose: Evaluate choroidal structural changes in preterm children with and without retinopathy of prematurity (ROP) using image binarization technique on swept-source optical coherence tomography (SS-OCT) scans.

Methods: Prospective case-control study. Forty-one (79 eyes) children aged 5-15 years with a history of preterm birth and 33 (63 eyes) age-matched full-term children were recruited.
