Femtosecond laser and microkeratome-assisted Descemet stripping endothelial ker...
Rosa, AM; Silva, MF; Quadrado, MJ; Costa, E; Marques, I; Murta, JNPurpose: To evaluate the use of a femtosecond laser combined with a microkeratome in the preparation of posterior corneal disks for Descemet stripping automated endothelial keratoplasty (DSAEK). Methods: This experimental study involved ultrathin DSAEK tissue preparation of 22 donor corneas unsuitable for transplantation. The first cut was performed with an Intralase® FS60 laser and the second cut with a Moria ...
Independent patterns of damage within magno-, parvo- and koniocellular pathways...
Silva, MF; Regateiro, FS; Forjaz, V; Januário, C; Freire-Gonçalves, A; Castelo-Branco, MSensory deficits have been documented in Parkinson's disease, in particular within the visual domain. However, ageing factors related to the brain and to neural and non-neural ocular structures could explain some of the previously reported results, in particular the claimed impairment within the koniocellular pathway. This study addressed visual impairment attributable to the magno- (luminance), parvo- (red-gre...
