One-port vs. three-port diagnostic vitrectomy for posterior segment diseases of unknown origin
ConclusionsIn this pilot study, the one-port diagnostic vitrectomy has proven to be as effective and safe as the three-port approach, allowing a reduction in surgical times. One-port diagnostic vitrectomy might be considered as the first option for those cases where more complex surgical procedures are not needed. (Source: International Ophthalmology)

Two different populations of M üller cells stabilize the structure of the fovea: an optical coherence tomography study
ConclusionsThe M üller cell cone provides the foveal stability in cases of a cystic disruption of the foveola. The structural stability of the outer foveal layers is mainly provided by the Müller cells of the foveal walls and parafovea; these cells also mediate the regeneration of the outer fovea in cases of a def ect of the central ONL.

High-risk features in primary versus secondary enucleated globes with advanced retinoblastoma: a retrospective histopathological study
ConclusionsSecondary enucleated globes with advanced RB show favorable histopathological findings mainly less mitosis. These eyes have significantly lower chance for harboring choroidal and ON invasion, thus mostly classified as pT1 or pT2a when compared to primarily enucleated globes. The decision for secondary enucleation was observed to be significantly delayed (8.0  months ± 9.8). Prompt decision for needed enucleation based on the response to primary treatment and careful histopathological examination of enucleated globes are essential to prevent disease-related mortality.
