Purpose: The aim of this study is to analyze the outcome of various techniques for a custom-made iris prosthesis implantation as part of reconstructive anterior segment surgery following traumatic aniridia.
Methods: This retrospective interventional study was done for 6 eyes that received an artificial iris as secondary reconstructive measure for photophobia and unsatisfactory vision following initial globe repair. Different implantation techniques were employed.
A 59-year-old male patient who suffered from a systemically metastasized, large extrascleral uveal melanoma recurrence of the left eye presented with active hemorrhage from the tumor. He had undergone proton beam irradiation for an epithelioid ciliary body melanoma 4 years before presentation and was lost to follow-up. Magnetic resonance angiography showed vascularization of the lesion via the ophthalmic and maxillary artery.

We studied the involvement of certain caspases in excitotoxic retinal ganglion cell death, which was experimentally induced in Brown Norway Rats by application of the glutamate receptor agonist N-methyl-D-aspartate (NMDA).
Methods: Animals were injected intravitreally with one of six caspase inhibitors (against caspases 1, 3, 4, 6, 8 and 9).

Background: Premature neuronal cell death is a feature of numerous central nervous system and eye diseases, including glaucoma. Neurons (including retinal ganglion cells, RGCs) are protected by several neurotrophic factors, among those the IL-6 family of cytokines. Lately, a novel member of the IL-6 family of cytokines has been identified and cloned.
