Follow-up of retinoblastoma using RetCam fluorescein angiography and correlation with clinical findings
CONCLUSION: RetCam wide-angle FA is useful to evaluate the tumor and associated vascular and retinal changes after treatment in RB. Regressed tumors demonstrate later fluorescein uptake in venous phases. Fluorescein angiographic changes in chorioretinal scars include window defects, visibility of choroidal vessels, scleral staining, and leakage from vessels. Retinal vascular leakage and peripheral non-perfusion can be seen in eyes with regressed stable tumors.PMID:36935642 | DOI:10.1177/11206721231163619

Eyesight to the Blind-Pharmacotherapy for Retinopathy of Prematurity
Neonatal Netw. 2023 Mar 1;42(2):88-95. doi: 10.1891/NN.2022-0054.ABSTRACTRetinopathy of prematurity (ROP) places preterm infants at significant risk for blindness. Angiogenesis of retinal blood vessels relies on vascular endothelial growth factor (VEGF) released in response to physiologic in utero hypoxia. Relative hyperoxia and disruption in the supply of growth factors after preterm birth lead to cessation of normal vascular growth. Recovery of VEGF production after 32 weeks' postmenstrual age results in aberrant vascular growth, including the formation of fibrous scars with the potential to detach the retina. Ablation o...
