BACKGROUND Intravitreal injection of human mesenchymal stem cells has been shown to be effective in slowing the progression of diabetic retinopathy in an animal model of chemically induced diabetes mellitus. We studied changes in growth factor levels released from human mesenchymal stem cells in the vitreous cavity as well as changes in growth factor levels(More)
PURPOSE To compare corneal pachymetry values measured by three different optical devices: Orbscan II, Pentacam HR and Sirius in healthy eyes. METHODS The central corneal thickness (CCT) of 102 eyes of 102 healthy subjects (mean age of 33.09 ± 8.72 years and mean refractive defect -4.11 ± 4.74 D) was measured by three different physicians using Orbscan II,(More)
This study was designed to evaluate the correlation between corneal biomechanical and morphological data in healthy eyes, eyes that underwent myopic photorefractive keratectomy (PRK), keratoconus affected eyes, and keratoconus affected eyes that underwent corneal collagen crosslinking (CCC). Complete clinical eye examination of all eyes was followed by(More)
Corneal morphological analysis has greatly improved in recent years, providing physicians with new and reliable parameters to study. Moreover, today corneal functional too is a routine analysis, thanks to biomechanical evaluation allowed by an ocular response analyzer (Reichert Ophthalmic Instrument, Depew, NY, USA). Corvis ST (OCULUS Optikgeräte GmbH,(More)
PURPOSE To evaluate the correlation between corneal biomechanical and morphological data in healthy eyes. METHODS A complete clinical eye examination of naïve eyes was followed by tomographic (Pentacam, Oculus, Wetzlar, Germany) and biomechanical (Corvis ST, Oculus, Wetzlar, Germany) evaluation. Linear regression between central corneal thickness (CCT),(More)
The influence of timolol on aqueous humour production has been well documented, nevertheless it is unknown the real mechanism by which timolol produces this process. We have conceived the hypothesis that any alteration of natrium and kalium content following topical treatment of timolol was the main cause of the lowering rate of aqueous humour production.(More)
PURPOSE We studied an Italian family affected by the autosomal dominant form of microcephaly and chorioretinal degeneration that was characterized by various degrees of clinical expression. METHODS An ophthalmologic examination, including visual acuity, visual field testing, an electroretinogram, and fundus photography, and a neurologic examination,(More)
PURPOSE The aim of this study is to describe the management of cataract and refractory glaucoma in a case of congenital aniridia (AN)-1. METHODS In an 18-year-old female patient affected by congenital AN, bilateral coloboma of the zonula and lens, cataract and glaucoma, pars plana vitrectomy, cataract extraction and subsequent transcorneal ciliary body(More)
An unusual foreign body in a 60-year-old man with ocular siderosis is described. A surgical needle was found in the eye after magnetic resonance imaging was performed for cerebral ischemia. As a general precaution in patients who have undergone any kind of surgery, it might be better to perform a plain x-ray before performing magnetic resonance imaging to(More)
