Avaliação da superfície ocular em pacientes com doença ocular da tireoide
… disease, affecting 25-50% of these patients. Ocular surface disease (OSD) is a multifactorial disorder characterised by an imbalance in tear film homeostasis, resulting from deficient tear production and/or excessive tear evaporation. In TED, the enlargement of the palpebral fissure, combined …

Ocular Compatibility of Hydrogels
… investigate the effects of long term wear on the ocular compatibility of hydrogel contact lenses with reference to the incidence of deposits. A number of spoilt lenses, representative of a wide range of lens chemistries were examined. A variety of analytical and histological techniques were …

Numerical modelling of ocular accommodation process
The ocular accommodation mechanism, as the main apparatus in the eye responsible for maintaining required vision quality when looking at objects at various distances to the eye, is one of the most vital mechanisms of the eye. Ocular accommodation is simultaneously a mechanical and an optical …

Ocular biomechanics of the anterior segment
… systems analysis of the CorvisST (CST) and Ocular Response Analyser (ORA) was performed. Pressure sensors were used to characterisation the airflow produced by the CST and the ORA. Distinct differences were observed between the central airflow pressures between the two devices: the CST …

Assessment of Ocular Accommodation in Humans
… implanted with an extended depth-of-focus intraocular lens. Using an absolute cut-off criteria of +0.30logMAR improved the repeatability and reliability of the depth-of-focus metrics over a cut-off criteria relative to the best corrected visual acuity. A swept-source anterior segment optical …

Lipoidal species in ocular spoilation processes
… is comparable to tears and chemically mimics ocular spoilation was also developed. This model allows the controlled study of extrinsic factors and hydrogel compositions. These studies show that unsaturated tear lipids, probably unsaturated fatty acids, are involved in the interfacial …

Ocular biomaterials and the anterior eye
… were also studied. Lasers have been employed in ocular surgery to correct refractive defects. If an irregular surface is ablated, an irregular surface is obtained. A hydrogel system was investigated that could be applied to the eye prior to ablation to create a smooth surface. Factors that may …

Evaluation of Ocular Pulse Amplitude-related Parameters measured by Dynamic Contour Tonometry and Ocular Blood Flow Analyzer
We performed this study to evaluate ocular rigidity-related factor (ORF) derived from ocular pulse amplitude (OPA) measurements with regard to the severity of glaucoma. This study was conducted in 31 eyes of 31 normal and 38 eyes of 38 normal tension glaucoma (NTG) patients with cross-sectional and …

Ocular Biometrics: Human Recognition in Challenging Conditions
… its usability as an accurate biometric. Ocular recognition has been recently proposed as a way to complement iris recognition in less constrained imaging conditions. Ocular recognition refers to the use of additional information around the eye as part of the biometric information. This …

Drug delivery strategies to overcome ocular hypertension
Glaucoma, a group of ocular diseases that cause optic nerve damage and vision loss, is the second leading cause of irreversible blindness worldwide. Current treatments, primarily eye drops, require frequent administration due to natural tear fluid turnover and blinking, which reduces patient …

Dendrimer Based Nanotherapeutics For Ocular Drug Delivery
… nanocarriers that are being investigated for ocular drug and gene delivery. Their favorable properties such as small size, multivalency and water solubility can provide significant opportunities for many biologically unstable drugs and allows potentially favorable ocular biodistribution. This …

Single-lens multi-ocular stereovision using prism
… this system can be categorized into: binocular, trinocular and multi-ocular systems which have been discussed separately. Two different approaches of modeling and determining this system are provided: one is based on camera calibration technique and another is based on geometrical …

Role of Macrophages in Ocular Surface Fibrosis
… could cause the transdifferentiation of ocular surface fibroblasts into myofibroblasts, thus contributing to oGVHD-associated fibrosis.</p> <p>Bone marrow cells were cultured in M-CSF to obtain M0 macrophages, which were subsequently polarized into M1 and M2 phenotypes using IFN-g + LPS …

Cell penetrating peptide for ocular drug delivery
… cascade in various in vitro and in vivo ocular models. Gap19 is an intracellularly acting connexin mimetic peptide, said to be Cx43 HC specific without effecting cell-to-cell communication. Gap19, however, has low cell permeability. To improve cell uptake, Gap19 was fused with the cell …

A Computational Model of the Ocular Lens
… model of the structure and function of the ocular lens, specifically the solute and fluid transport in the lens. The modelling framework was based on finite volume methods. The intracellular and extracellular solute fluxes were modelled using the Nernst-Plank equation with an extra term to …
