PURPOSE The aims of our study were to compare the ocular microbial communities of humans with and without blepharitis in an attempt to elucidate which microorganisms may cause blepharitis. METHODS Bacterial 16S rRNA genes of eyelash and tear samples from seven blepharitis patients and four healthy controls were sequenced using a pyrosequencing method, and their bacterial community structures ...

purpose: to report a case of metastatic tumor to the right upper eyelid originating from a lung adenocarcinoma without any systemic signs. case report: a 68-year-old man had a two-month history of painless swelling in the right upper eyelid. the tumor slowly grew. two years before his presentation, he had received chemotherapy for lung cancer for one year. systemic and ocular examinations were ...

PURPOSE Trichiasis is an acquired condition in which the eyelashes are directed posteriorly, touching the surface of the cornea. It poses a complex therapeutic problem. Despite several therapeutic options (epilation, electroepilation, cryotherapy, laser ablation and standard surgical techniques), relapse is frequent. METHODS A prospective, nonmasked study was conducted to determine the effica...

Most fungal infections of the cornea are secondary infections, caused by opportunis­ tic fungi that have invaded a diseased cornea or one that has been treated with corticosteroids or broad-spectrum antibiotics. Two ex­ ceptions are corneal infections due to Can­ dida albicans or Aspergillus species; these may infect an apparently normal cornea af­ ter minimal trauma. Superficial mycotic infect...

The growing concern with security and access control to places and sensitive information has contributed for the increased utilization of biometric systems. Biometry is the name given to the techniques used to recognize people automatically through physical and behavioural characteristics of the human body such as those found on the face, fingerprint, hand geometry, iris, signature or voice. Fr...

A biometric system provides automatic identification of an individual based on a unique feature or characteristic possessed by the individual. Iris recognition is regarded as the most reliable and accurate biometric identification system available. Most commercial iris recognition systems use patented algorithms developed by Daugman, and these algorithms are able to produce perfect recognition ...
