Preparation Explain the procedure and advise the • patient that it will cause some very brief discomfort The patient, helper, and examiner • should be positioned appropriately. The helper can hold the torch (Figure 1). Method Instil the local anaesthetic eye drops • Using magnification, identify the • eyelashes which need epilating (Figure 2) For lower eyelashes: ask the patient to look up, • f...

PURPOSE To describe the ophthalmic manifestations in a series of children with congenital lamellar ichthyosis. These cases presented with varying types of eyelid abnormality associated with the systemic disease. The clinical features and ophthalmic management were studied. METHODS The case histories of three children presenting to the oculoplastic clinic were reviewed. All were diagnosed with...

Iris recognition is one of the most reliable methods for identification. In general, itconsists of image acquisition, iris segmentation, feature extraction and matching. Among them, iris segmentation has an important role on the performance of any iris recognition system. Eyes nonlinear movement, occlusion, and specular reflection are main challenges for any iris segmentation method. In thi...

Accurate iris segmentation is presented in this paper, which is composed of two parts, reflection detection and eyelash detection. Eyelashes are classified into two categories, separable and multiple. An edge detector is applied to detect separable eyelashes and intensity variances are used to recognize multiple eyelashes. Reflection is also divided into two types, strong and weak. A threshold ...

The biometric system is based on human's behavioral and physical characteristics. Among all of these, iris has unique structure, higher accuracy and it can remain stable over a person's life. Iris recognition is the method by which system recognize a person by their unique identical feature found in the eye. Iris recognition technology includes four subsections as, capturing of the ir...

Trachoma, a chronic keratoconjunctivitis, is caused by episodes of infection with Chlamydia trachomatis, an obligate intracellular bacterium. Only serovars A, B, Ba, and C are implicated in trachoma. Trachoma is the second leading cause of blindness worldwide [1]. According to the World Health Organization, currently 84 million people, mostly children, have active disease, and another 7.6 milli...

PURPOSE/METHODS We report the case of a 73-year-old white female suffering from Merkel cell carcinoma (MCC) of the eyelid with an evolution of two and half months. MCC is a cutaneous neuroendocrine malignant tumor arising from Merkel cells. These cells are common along the eyelid margin in between the eyelashes. It is infrequent but highly aggressive and with potential metastases. Immunohistoch...
