Erlotinib is among the oral EGFR-tyrosine kinase inhibitors used to treat non-small cell lung cancer. The common side effects of erlotinib include acne form rash and diarrhea. Eyelash trichomegaly and alterations of scalp hair are rarely observed symptoms. In the present study, we report changes in eyelash trichomegaly and scalp hair in six cases of pulmonary adenocarcinoma patients that had be...

Iris masks are essential in iris recognition. The purpose of having a good iris mask is to indicate which part of iris texture map is useful and which part is occluded or contains noisy artifacts such as eyelashes, eyelids and specular re ections. The accuracy of the iris mask is extremely important. The performance of the iris recognition system will decrease dramatically when iris mask is ina...

PURPOSE Trachomatous trichiasis (TT) is usually described as a cicatricial entropion of the upper lid; however, other forms of trichiasis have been reported. This variation in clinical phenotype is potentially important for treatment guidelines. Therefore, this study was conducted to investigate the range of disease type and severity encompassed by TT. METHODS Individuals presenting with TT t...

A 10-year old boy accidently splashed acrylic adhesive in his left eye. I separated the eyelids by cutting adherent eyelashes with the use of a biomicroscope for magnification illumination. Tests with rabbits demonstrated that the solvent nitromethane dissolved the adhesions but diluted the glue and led to adhesions between the tarsal portion of the eyelid and the cornea. I used acrylic adhesio...

Iris recognition has become a popular research in recent years due to its reliability and nearly perfect recognition rates. Iris recognition system has three main stages: image preprocessing, feature extraction and template matching. In the preprocessing stage, iris segmentation is critical to the success of subsequent feature extraction and template matching stages. If the iris region is not c...

Iris recognition, a relatively new biometric technology, has great advantages, such as variability, stability and security, thus it is the most promising for high security environments. A new iris recognition algorithm is proposed in this paper, which adopts Independent Component Analysis (ICA) to extract iris texture feature and competitive learning mechanism to recognize iris pattern. Experim...

PURPOSE Evaluation of the magnitude and pattern of bacterial contamination of needle points with conjunctival bacteria during the intravitreal injection. Analysis of the efficacy of preinjection prophylaxis. METHODS A total of 550 intravitreal injections were done in 414 patients (n=425 eyes). A total of 289 patients were injected once, while 125 patients received several injections. Before t...

Trachoma is the most common infectious cause of blindness worldwide. It afflicts some of the poorest regions of the globe, predominantly in Africa and Asia. The disease is initiated in early childhood by repeated infection of the ocular surface by Chlamydia trachomatis. This triggers recurrent chronic inflammatory episodes, leading to the development of conjunctival scarring. This scar tissue c...

Cilia are normally found at the eyelid margin, while ectopic cilia are one or more lash follicles appearing in an abnormal position within the eyelid. We herein report two cases of cilia located in the palpebral conjunctiva. A 31-year-old female and a 46-year-old male presented with ectopic cilia in the superior palpebral conjunctiva. Histopathological study of the excised ectopic cilia and rel...
