A case of anterior persistent hyperplastic primary vitreous associated with morning glory disc anomaly and retinopathy of prematurity like retinopathy in a term-born child

Background Association of morning glory disc anomaly (MGDA) with persistent hyperplastic primary vitreous (PHPV) has been reported earlier. Retinopathy of prematurity (ROP) like retinopathy in preterm babies with optic disc anomalies has also been published. Our case is unique in terms of presence MGDA, PHPV, unilateral ROP like retinopathy in a term infant with normal birth weight. Case presentation A 5-month-old girl, born at term with a birth weight of 3750 g, presented with anterior PHPV, MGDA and ROP like retinopathy. In order to prevent retinal detachment, she received 360 degree barrage laser photocoagulation at the edge of the optic disc excavation of the left eye. In the follow-up a month later, laser scars were found in her left fundus without other complications. Conclusion PHPV and MGDA with ROP like retinopathy in term and normal weight baby is rare. The peripheral avascular retinal area, caused by the dragging of the defected optic disc, might have been more vulnerable to the oxygen change after birth which resulted in ROP like retinopathy. High sensitivity to oxygen results in a series of changes such as upregulation of VEGF and IGF-1 may cause ROP-like retinopathy.

Persistent Hyperplastic Primary Vitreous with Microphthalmia and Coloboma in a Patient with Okur-Chung Neurodevelopmental Syndrome

Okur-Chung neurodevelopmental syndrome is a rare autosomal dominant disorder caused by pathogenic variants in <i>CSNK2A1</i>, which encodes the alpha 1 catalytic subunit of ­casein kinase II. This syndrome is characterized by intellectual disability, developmental delay, and multisystemic ­abnormalities including those of the brain, extremities, and skin as well as cardiovascular, gastrointestinal, and immune systems. In this study, we describe a 5-year-old boy with a de novo novel nonsense variant in <i>CSNK2A1</i>, NM_001895.3:c.319C&#x3e;T (p.Arg107*). He showed bilateral persistent hyperplastic primary vitreous with microphthalmia, lens dysplasia, and coloboma. Ocular manifestations are very rare in this syndrome, and this study expands the spectrum of the clinical presentations of this syndrome.
