Retinopathy of prematurity (ROP), a leading cause of childhood blindness, has historically been associated with blindness from overgrowth of blood vessels from the retina into the vitreous that lead to complex retinal detachments. Our understanding of ROP has evolved with the survival of extremely low-birthweight infants and includes not only overgrowth of blood vessels, but also insufficient developmental retinal vascular growth in early phases of the disease. Our current treatments of ROP have focused on methods to improve perinatal and prenatal care, reduce premature birth, and prevent early phases of ROP. Nonetheless, addressing vasoproliferation in treatment-warranted eyes remains the mainstay of management. Two main treatment strategies co-exist today: laser treatment, which has been the standard of care since the 1990s, and anti-VEGF injections, which have been used since early reports in 2007 (Travassos et al. in Ophthalmic Surg Lasers Imaging, 38:233-237, https://doi.org/10.3928/15428877-20070501-09 , 2007, Shah et al. in Indian J Ophthalmol 55:75-76, https://doi.org/10.4103/0301-4738.29505 , 2007, Quiroz-Mercado et al. in Semin Ophthalmol 22:109-125, https://doi.org/10.1080/08820530701420082 , 2007).

Extreme Prematurity: A Case Report on the Importance of Multidisciplinary Consultations Before and After Maternity Ward Discharge.
Cureus
December 2024
Pediatrics, Carol Davila University of Medicine and Pharmacy, Bucharest, ROU.
Extreme prematurity involves a series of complications that a multidisciplinary team should manage. Taking into account the risks related to premature newborns, such as maternal-fetal infections, intrauterine growth restriction, and certain comorbidities associated with young gestational age, our objective is to highlight the importance of a multidisciplinary team in approaching cases with an unfavorable prognosis. This is a case report of an extremely preterm newborn who came from a high-risk pregnancy and needed long-term hospitalization in the Neonatal Intensive Care Unit (NICU) and mechanical ventilation.

Department of Ophthalmology, Zhujiang Hospital, Southern Medical University, No. 253, Gongye Avenue Middle, Guangzhou, 510282, Guangdong, China.
Background: To evaluate the effect and factors associated with the reactivation of retinopathy of prematurity (ROP) after intravitreal conbercept or aflibercept.
Methods: We retrospectively reviewed the medical records of 176 eyes diagnosed with ROP and treated with anti-VEGF therapy between January 2018 and September 2022. The rate of reactivation and complications were assessed during the follow-up period.

Background: The aim of the study was to investigate the quantitative differences between severe stage 3 and stage 4A retinopathy of prematurity (ROP) by evaluating the pre-treatment fundus photographs.
Methods: Thirty-three eyes with clinical diagnosed as severe stage 3 were classified as severe stage 3 group. Twenty-two eyes with retinal detachment without foveal involvement were classified as stage 4A group.

Background: To establish an objective method for assessing plus disease severity in retinopathy of prematurity.
Methods: Six images of plus diseases that were color-coded according to severity and published in the International Classification of Retinopathy of Prematurity, Third Edition (ICROP3) were analyzed. These images were individually processed, and the best-fit curve and vessel course in zone I were obtained using ImageJ software.
Automated Quantification of Retinopathy of Prematurity Stage via Ultrawidefield OCT.
Ophthalmol Sci
November 2024
Casey Eye Institute, Oregon Health and Science University, Portland, Oregon.
Purpose: Retinopathy of prematurity (ROP) stage is defined by the visual appearance of the vascular-avascular border, which reflects a spectrum of pathologic neurovascular tissue (NVT). Previous work demonstrated that the thickness of the ridge lesion, measured using OCT, corresponds to higher clinical diagnosis of stage. This study evaluates whether the volume of anomalous NVT (ANVTV), defined as abnormal tissue protruding from the regular contour of the retina, can be measured automatically using deep learning to develop quantitative OCT-based biomarkers in ROP.
