PURPOSE To identify and compare the phosphorylated lipids in normal and dry eye rabbit tears using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS). METHODS MALDI-TOF MS studies were performed on tear samples from normal and dry eyes of female New Zealand White rabbits. Experimental dry eye was induced by complete removal of the main and accessory la...

To investigate the effects of visual disruption on contrast letter thresholds of the non-affected eye, subjects with one eye enucleated, strabismic subjects using the non-deviating eye and normal control subjects were asked to identify letters on eye charts and single letter cards which varied in contrast (between 4 and 96%) and size. At all contrast, contrast letter acuity of eye enucleated su...

Objective- The aim of this study was to evaluate ultrasonographic appearance of the normal eye and obtaining reference values of ocular structures in Iranian native donkey. Design- Experimental study. Animals- Five Iranian native donkeys. Procedures- After preparation of the animals, ocular structures were ima...

purpose : to report an unusual presentation of chandler syndrome case report : a 22-year-old female came to our clinic with complaint of progressive visual loss in her left eye since three days ago. she had a history of trauma with finger-nail to her left eye eight days ago and had been managed with topical antibiotic. in her examination, the left eye had visual acuity (va) of counting finger a...

Introduction To report the development of unilateral keratoconus in a healthy male after persistent unilateral eye rubbing by the nondominant hand which was not needed for professional activities. Methods Observational case report. Results A 60-year-old male was first seen in our clinic due to decreased vision in his left eye. Slit-lamp biomicroscopy of the left eye revealed Vogt's striae, ...

PURPOSE To report dry eye patients' functional visual acuity, which was measured after sustained eye opening for 10-20 seconds, as a simulation of visual function of daily acts of gazing, which is defined as looking at an object with involuntary blink suppression. METHODS Interventional clinical nonrandomized comparative trial. We measured ordinary best-corrected visual acuity and functional ...

1. The relation between the physiological pattern of ocular dominance and the anatomical distribution of geniculocortical afferents serving each eye was studied in layer IV of the primary visual cortex of normal and monocularly deprived cats. 2. One eye was injected with radioactive label. After allowing sufficient time for transeuronal transport, micro-electrode recordings were made, and the g...

Ocular dominance in extrastriate visual cortex of cats with behaviorally defined strabismic amblyopia was studied using extracellular recording techniques. In area 18, the amblyopic eye drove about as many cells as the normal one. In area posteromedial lateral suprasylvian area (PMLS), about 60% of the cells responded exclusively to stimulation of the normal eye and 30% to stimulation of the am...

-Cats were raised with one eye sutured and the other removed. We wished to determine whether: ( 1) the deprived eye would develop a visual field of normal extent (135’) as might be expected on the basis of the competitive advantage that this eye enjoys within the geniculocortical pathways. or (2) the deprived eye, in the absence of pattern vision, would develop only 90’ of vision. as happens in...

background and aims: epstein-barr (ebv) virus infection is very common in the population. virus belongs to the family herpesviridae, whose representatives are characterized by the ability to cause the human body latent persistent infections. the goal of study is to assess ebv infection frequency and pcr method in the choice of ebv in inflammatory eye disease, comparing with ebv presence in eye ...
