Introduction: Pupil and iris disorders form an important category of eye diseases. Accurate segmentation the pupil is first most step in automatic diagnosis diseases related to iris. Most existing methods do not have enough accuracy are sensitive effects noise specular spot reflection. In addition, images used these usually limitations, such as viewing angle . Method: proposed algorithm, a stab...

The term “iris” refers to the highly textured annular portion of the human eye that is externally visible. An iris recognition system exploits the richness of these textural patterns to distinguish individuals. Iris recognition systems are being used in a number of human recognition applications such as access control, national ID schemes, border control, etc. To capture the rich textural infor...

PURPOSE To investigate the effect of squalamine, an antiangiogenic aminosterol, in an experimental model of iris neovascularization. METHODS Iris neovascularization was created in cynomolgus monkeys by occluding retinal veins with an argon laser and inducing persistent hypotony with a central corneal suture. Twenty-four eyes were treated in three groups. In Group 1, four eyes were injected in...

In this paper, a new iris localization method for mobile devices is presented. Our system uses both intensity and saturation threshold on the captured eye images to determine iris boundary and sclera area, respectively. Estimated iris boundary pixels which have been placed outside the sclera will be removed. The remaining pixels are mainly the boundary of iris inside the sclera. Then, circular ...

Ophthalmoscopic evidence of leprous lesions of the fundus was recently seen in a case of lepromatous leprosy of fifteen years duration. These lesions are truly leprous, we believe, for they are identical in contour, color and waxy refractile characteristics with those seen on the iris with the slit lamp, and which have been proven by our routine microscopic sections to contain typical lepra cel...

Introduction and purpose Uveal melanoma is the most common primary intraocular malignancy in adults. Most of them arise choroid ciliary body, whereas 2-5 % cases are located to iris. Nevertheless, during last few decades incidence this neoplasm has been increasing. The aim study discuss risk factors, clinical features methods diagnosis treatment iris melanoma. Description state knowledge Iris m...

Amblyopia is a neurological vision disorder that studies show affects two to five percent of the population. Current methods of treatment produce the best visual outcome if the condition is identified early in the patient's life. Several early screening procedures are aimed at finding the condition while the patient is a child, including an automated vision screening system developed by Cibis, ...
