The abuse of methamphetamine (MA) and other psychostimulants is a social and medical problem. In particular, the use of these drugs by pregnant women results in an increased number of children exposed prenatally to psychostimulants. Our previous work has demonstrated that prenatal exposure to MA affects the normal development of the rat visual system due to(More)
Several refractive and therapeutic treatments as well as several ocular or systemic diseases might induce changes in the mechanical resistance of the cornea. Furthermore, intraocular pressure measurement, one of the most used clinical tools, is also highly dependent on this characteristic. Corneal biomechanical properties can be measured now in the clinical(More)
Purpose. To determine whether the retinal pigment epithelium (RPE) exhibits any substantial phototoxicity and, if so, which arc the major cbromophorcs involved. M&o&. Intact human RF'E cells were isolated from the posterior poles of human and bovine eyes. Lipofoscm and melanosome granules were also isolated from human donor eyes. Action spectra of oxygen(More)
Corneal collagen crosslinking (CXL) is a promising new treatment modality designed to stabilize or decrease the progression of keratoconus, as well as other corneal-thinning processes such as ectasia after LASIK or PRK. An increase in corneal biomechanical strength after CXL slows the progression of keratoconus and other forms of ectasia with few reported(More)
Retinal abnormalities have been described in both animals and humans exposed to cocaine during development. The present study was designed to examine the morphological repercussions of neonatal exposure to cocaine on the developing retina of the rat. Male Wistar rats were given 15 mg/kg body weight per day of cocaine hydrochloride subcutaneously on(More)
Purpose. To compare the characteristics of asymmetric keratoconic eyes and normal eyes by Fourier domain optical coherence tomography (OCT) corneal mapping. Methods. Retrospective corneal and epithelial thickness OCT data for 74 patients were compared in three groups of eyes: keratoconic (n = 22) and normal fellow eyes (n = 22) in patients with asymmetric(More)
w The human wrnea is a densely innervated struchxe. However, data on nerve fiber (NF) distribution in tbe human cornea are scarce possibly due to fast post mortem degeneration. Therefore, moat descriptions on comeal innervation are based on studies in rats and rabbits. Tbe present study is focussed on the ulaastruaure of NF's in the central and peripheral(More)
We determined the effects of cocaine hydrochloride (15 mg/kg body weight/day) or amphetamine sulfate (25 mg/kg body weight/day) on the optic nerve in groups of rats exposed from postnatal day 1 to 30. Qualitative and quantitative studies of cross-sections of the optic nerves showed different patterns of organization, namely the presence of degenerative(More)
Puroose: The present study investigated whether flupirtine, a non-opioid analgesic agent with some NMDA antagonistic properties in viva and in vitro, protects from ischaemic retinal injury. Methods and Results: Retinal ischaemia was induced either by transient occlusion of both common carotid arteries in the rat or by a " suction cup procedure " which(More)
The effects of neonatal exposure to cocaine upon the structure of the visual system are poorly understood despite the evidence of eye abnormalities in infants exposed in utero to cocaine. We previously demonstrated alterations in the optic nerve of rats exposed neonatally to cocaine, although no changes were detected in the number of its axons. This study(More)
