Intravitreal luxated lens stuck on the optic disc: a case report.

Background: We encountered a rare patient with lens luxation in which the lens had become stuck on the optic disc. Findings obtained during vitreous surgery suggested that the luxated lens had become stuck on the optic disc via residual vitreous gel.

Case Presentation: An 88-year-old Japanese man experienced lens luxation into the inferior vitreous cavity while undergoing treatment for glaucoma in his left eye.

Expression of a hyaluronic acid-binding proteoglycan (versican) in the cynomolgus monkey eye.

The expression of versican, a hyaluronic acid (HA)-binding protein, during the development and differentiation of the retina has been reported. In this study, we performed histochemical and immunohistological analysis of HA and versican from the ciliary body to the retina in cynomolgus monkey eyes. Paraffin-embedded sections of cynomolgus monkey eyes, including from the ciliary body to the macular region, were prepared.

Treatment of massive subretinal hematoma associated with age-related macular degeneration using vitrectomy with intentional giant tear.

The purpose of this study was to report the surgical outcomes after creating a 120° intentional giant retinal tear for use in removing hemorrhage and subretinal proliferative tissue in patients with polypoidal choroidal vasculopathy (PCV) or age-related macular degeneration (ARMD). This study involved 12 eyes of 12 patients (10 eyes: PCV, 2 eyes: ARMD). After removal of the lens in phakic eyes, we performed a vitrectomy with artificial posterior vitreous detachment.
