purpose: to assess orbital color doppler ultrasonography (cdu) parameters of patients with manifest hyperopia in comparison to the emmetropes methods: forty eyes of 40 patients presenting with manifest hyperopia were included into the study. forty eyes of 40 emmetropes healthy volunteers also were examined as the control group. we have evaluated ophthalmic artery (oa), central retinal artery (c...

The aims of this study were to assess whether the increased oxidative stress in affected tissues is reflected by serum lipid peroxidation and to check for alterations in serum levels of extracellular antioxidants and antioxidant enzyme activities in patients with Behcet's disease (BD). Serum malondialdehyde (MDA) and ceruloplasmin (Cp) levels and CuZn-superoxide dismutase (CuZn-SOD) and glutath...

OBJECTIVES To investigate the prevalence of ocular injuries in a large population of boxers over a period of 16 years, in particular, the most severe lesions that may be vision threatening. METHODS Clinical records of the medical archive of the Italian Boxing Federation were analysed. A total of 1032 boxers were examined from February 1982 to October 1998. A complete ophthalmological history ...

FOXC2 mutations cause the lymphatic/ocular disorder Lymphedema-Distichiasis (LD), and Foxc2 haploinsufficient mice mimic this disorder. To determine if FOXC2 overexpression might also cause lymphatic and/or ocular abnormalities, we performed dynamic lymphatic imaging (Evans blue dye), ocular tissue examination, and metabolic profiles in mice: transgenic for FOXC2 with an adipocyte (aP2) promote...

Synaptic plasticity is a multistep process in which rapid, early phases eventually give way to slower, more enduring stages. Diverse forms of synaptic change share a common requirement for protein synthesis in the late stages of plasticity, which are often associated with structural rearrangements. Ocular dominance plasticity in the primary visual cortex (V1) is a long-lasting form of activity-...

Pterygium is a fibrovascular lesion of the ocular surface that can display an aggressive clinical behavior and, occasionally, threaten vision. Although there is no consensus on its pathogenesis, recent evidence suggests that it is a proliferative, rather than degenerative condition strongly correlated with exposure to ultraviolet radiation (UVR) of solar light. Molecular genetic alterations rep...

Both the innate and the adaptive immune systems are involved in the pathogenic processes following ischemia-reperfusion injury. We analyzed the possible correlation between the duration of ischemia and autoantibody diversification in a model of ocular ischemia. Rats were subjected to 30, 45, or 90 min of ischemia, and retinal ganglion cell (RGC) density and antibody reactivity were analyzed via...
