Compared with focal laser, half-dose PDT may facilitate earlier resolution of macular detachment and earlier recovery of central retinal function. However, at 3 months after treatment and thereafter, no difference in anatomical and functional recovery was noted between the two modalities of treatment.
In Korea, most children with retinoblastoma showed an advanced stage of tumour at the time of diagnosis and although they were treated with an updated therapeutic approach according to the newly introduced classification, the rate of globe preservation did not reach that of developed countries. Increased surveillance should be performed.
This study demonstrates that engorgement of the vortex vein was observed more frequently in the eyes with PCV. Such a finding was associated with choroidal thickening and choroidal vascular hyperpermeability. These indicate that the engorgement of the vortex vein might be involved in the pathogenic mechanisms of PCV.
LGH is a highly sensitive and specific ICGA finding for the diagnosis of PCV. Increased surveillance should be implemented in eyes in which LGH persists after PDT.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
