over a period of four years, we followed 200 male cases (female patients were excluded from this study because from early childhood, the majority of iranian girls have their ears pierced which tends to distort the ear lobe and renders the diagnosis of the crease difficult) of proved coronary artery disease (angina pectoris, coronary insufficiency, and myocardial infarction) in a private clinic ...

BACKGROUND The purpose of this work was to report on the performance of medial blepharosynechioplasty (MBSP), a newly devised technique for treating severe dry eye. METHODS In this retrospective, nonrandomized clinical trial, three cases with severe dry eye (Sjögren's syndrome) associated with repeated punctal plug loss were treated using MBSP to create a synechia between the upper and lower ...

The face region immediately surrounding one, or both, eyes is called the periocular region. This paper presents an iris segmentation algorithm for challenging periocular images based on a novel iterative ray detection segmentation scheme. Our goal is to convey some of the difficulties in extracting the iris structure in images of the eye characterized by variations in illumination, eye-lid and ...

INTRODUCTION In literature, many different types of foreign objects have been found to have caused eye injuries. These objects can range from organic to inorganic matter such as glass, wood, pencil, nails and fishhooks. Once the injury is recognized, removal of the foreign body and technique used in the management of the injury is very important to reduce further ocular damage. This case report...

BACKGROUND The influence of orbital fractures and their repair on the rate of deformities of the lower eyelid is an ongoing source of discussion in the literature. Most of the present studies include isolated blow-out as well as combined orbital fractures. MATERIAL AND METHODS We present a retrospective evaluation of a series of 100 patients after isolated blow-out fracture repair using refer...

The effects of short-term unilateral form vision deprivation by suturing the lids in macaques were evaluated in terms of cortical neuronal electrophysiology and cell sizes in the lateral geniculate nucleus (LGN). The results show that cell shrinkage in the LGN is proportional to the duration of lid closure, with the parvocellular laminae being somewhat more sensitive than the magnocellular laye...
