Both IOLs reduced light-induced RPE damage. The UV- and blue light-filtering IOL reduced damage more than the conventional IOL. This supports the hypothesis that blue light-filtering IOLs may prevent retinal damage in clinical use.

The presence of epiretinal cells at the ILM in all macular hole stages strongly suggests a substantial involvement of cell migration and proliferation in the course of macular hole development. Glial cells and hyalocytes play the predominant role in epiretinal cell proliferation. Given the co-expression of glial cell and hyalocyte markers, transdifferentiation of epiretinal cells needs further elucidation, especially with respect to αSMA-positive cells leading to traction at the vitreoretinal interface.

The systematic evaluation of dyes for intraocular use seems mandatory. In this study four dyes were identified with effective staining characteristics, with two of these dyes having no detectable toxic effect on RPE cells in vitro.

To assess quality of life in uveal melanoma patients within the first and second year after CyberKnife radiosurgery. Overall, 91 uveal melanoma patients were evaluated for quality of life through the Short-form (SF-12) Health Survey at baseline and at every follow-up visit over 2 years after CyberKnife radiosurgery. Statistical analysis was carried out using SF Health Outcomes Scoring Software and included subgroup analysis of patients developing secondary glaucoma and of patients maintaining a best corrected visual acuity (BCVA) of the treated eye of 0.5 log(MAR) or better. Analysis of variance, GreenhouseGeisser correction, Student's t-test, and Fisher's exact test were used to determine statistical significance. Physical Functioning (PF) and Role Physical (RP) showed a significant decrease after CyberKnife radiosurgery, whereas Mental Health (MH) improved (P = 0.007, P < 0.0001 and P = 0.023). MH and Social Functioning (SF) increased significantly (P = 0.0003 and 0.026) in the no glaucoma group, MH being higher compared with glaucoma patients (P = 0.02). PF and RP were significantly higher in patients with higher BCVA at the second followup (P = 0.02). RP decreased in patients with BCVA < 0.5 log(MAR) (P = 0.013). Vitality (VT) increased significantly in patients whose BCVA could be preserved (P = 0.031). Neither tumor localization nor size influenced the development of secondary glaucoma or change in BCVA. Although PF and RP decreased over time, MH improved continuously. Prevention of secondary glaucoma has a significant influence on both SF and MH, whereas preservation of BCVA affects VT. Emotional stability throughout follow-up contributes positively toward overall quality of life. CyberKnife radiosurgery may contribute to attenuation of emotional distress in uveal melanoma patients.
