Hemi-Central Retinal Vein Occlusion in a Premature Infant: A Case Report

This study reports the case of an infant patient with organized vitreous hemorrhage (VH) due to hemi-central retinal vein occlusion (Hemi-CRVO) secondary to thrombocytosis.

A twenty-seven-day-old female infant with the gestational age of 30 weeks and 2040 grams weight at the time of birth and the history of a twenty-five-day admission in a neonatal intensive care unit (NICU) due to idiopathic hydrops was referred to the retinopathy of prematurity (ROP) clinic of the Khatam-al-Anbia Eye Hospital, for usual ROP screening. We found an organized VH in her left eye; so, we vitrectomized her eye. With the diagnosis of hemi-CRVO due to thrombocytosis, she is under observation.

In this report, thrombocytosis showed to be a cause of hemi-CRVO; and the patient’s laboratory test review is important in such cases
