Atypical central vein occlusions can be the rare cause of a subhyaloid macular hemorrhage. A Valsalva's manoeuver could have caused in our patient the subhyaloid macular and the preretinal bleedings. The temporarily raised venous pressure could have been responsible for the central vein occlusion, secondarily causing the occlusion of a cilioretinal paramacular artery.
Allogen cartilage grafts to a clear corneal pounch do not induce an inflammatory reaction. Therefore, autologous cartilage prepared of ears seems to be useful biological material in ophthalmologic surgical procedures, for example to fill up corneal defects. To investigate if cartilage grafts will be helpful to stop neovascularisation in keratoplasty further studies with vascularisized corneas are necessary.
A 7-month-old female infant presented with a heterochromia and an anisocoria. A spontaneous hyphema and a secondary glaucoma had developed. Under topical and systemic steroid therapy the eye improved continuously. At the time of the last ocular examination the hyphema had resorbed, and the intraocular pressure was normal. Heterochromia had almost completely vanished, and dilation of the pupil was much better. Since even a massive juvenile xanthogranuloma of the iris responds well to steroids, operative and radiation treatment should be limited to cases refractory to antiinflammatory drug therapy.
A 23-year-old female presented with a yellow-brownish, asymptomatic tumour of the bulbar conjunctiva in her left eye. The lesion had been detected 5 years previously and had grown since then. Prior to presentation there were 2 episodes of intratumoral hemorrhage. Funduscopy revealed tortuous vessels on the left. Complete tumour excision was performed. Histology showed numerous channels lined by a flat endothelium, and inflammatory cells in the fibrous septae. A diagnosis of a conjunctival lymphangioma was established. The tortuosity of the retinal vessels was probably associated by chance or caused by an undetected orbital lymphangioma.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
