Biological soft tissue are of special interest to the researchers as they exhibit unique anisotropic behaviour and are leading contributors to the quality of outcome of a surgical procedure. In this paper attempts have been made to review the strategy adopted by various researchers for conducting experiments in order to understand the mechanical behaviour of cornea and their use in ophthalmolog...

PURPOSE To test the possibility that androgen directly affects the corneal cells, the possible occurrence of androgen receptor (AR) in the cornea and other eye tissues of mice was examined. METHODS To examine the occurrence of AR protein in the mouse eye tissues, an immunocytochemical method was used. To examine the occurrence of AR mRNA in the cornea and lens, reverse transcription-polymeras...

Disease Course Pain is almost always associated with the onset of Mooren’s ulcer. One or both eyes may be involved at either the same time or one following the other. Approximately two thirds of cases affect one eye only. Mooren’s ulcer is more common in men than women. The eye is usually red and the vision may or may not be reduced. Damage begins at the edge of the cornea (near the junction be...

OBJECTIVE To use amniotic membranes as a buffer between the cornea and radioactive eye plaques. METHODS Six melanomas were treated with ophthalmic plaque radiation therapy. Plaque-tumor localization required that a portion of the gold plaque touch the cornea during treatment. To enhance patient comfort and protect the cornea, an (0.1-mm-thick) amniotic membrane was interposed between the meta...

To understand the corneal regeneration induced by bevacizumab, we investigated the structure changes of stroma and basement membrane regeneration. A Stick soaked in 0.5 N NaOH onto the mouse cornea and 2.5 mg/ml of bevacizumab was delivered into an alkali-burned cornea (2 μl) by subconjunctival injections at 1 hour and 4 days after injury. At 7 days after injury, basement membrane regeneration ...

Aim. To report a case of refractory fungal keratitis caused by Scedosporium apiospermum. Methods. Interventional case report. Results. A 47-year-old Malay housewife presented with left eye cornea ulcer as her first presentation of diabetes mellitus. There was no history of ocular trauma, contact lens used, or cornea foreign body. Scedosporium apiospermum was isolated from the cornea scrapping. ...

Human eye is made of a number of structural components to deliver vision, and cornea is the front window of the eye. Human cornea is made of soft biological materials. It is unfriendly for exposures to the common energy levels of X-ray scans for repeated probing of its structural architecture. Here we study an alternative imaging methodology by using a normal white-light source. By exploiting t...

The influence of tobacco smoke on the dielectric properties of rat cornea were measured in vitro over the frequency range of the electric field of 500Hz-100kHz and in temperatures of the air from 25 to 150°C. The temperature dependencies of the loss tangent for both healthy and smoky cornea represent the relation between the energy lost and the energy stored in the epithelium-stromal-endotheliu...

PURPOSE To assess inflammatory involvement of cornea in dry eye by means of confocal microscopy, evaluating the presence and distribution of Langherans cells (LCs). METHODS 98 eyes of 49 subjects were enrolled: 18 subjects affected by Sjögren Syndrome Dry Eye (SSDE), 17 with Non-Sjögren Syndrome Dry Eye (NSSDE), 14 healthy volunteeers. Dry eye symptoms, tear film, ocular surface damage and co...

Background and Objectives: Thyroid gland because of its superficial location is amenable to direct physical examination. Clinical assessment of thyroid lesions by means of physical examination, thyroid scans and ultrasonography is not completely reliable. Fine needle aspiration cytology (FNAC) is the most cost-effective, safe and an initial diagnostic test in the pre-operative evaluation of thy...
