purpose: to determine the prevalence of ocular manifestations in marfan’s syndrome. methods: this cross-sectional study was performed on 43 patients referred to ophthalmology clinics of yazd medical university over 27 months. common ocular manifestations of marfan’s syndrome including lens dislocation, corneal disorders, retinal conditions, glaucoma were evaluated. results: the study included 2...

From a study of a large number of brothers and sisters suffering from concomitant squint, the following data were obtained: (1) 42-9% of the patients showed congenital strabismus. (2) In 96-5% of the sibs strabismus was of the same type. (3) The presence of a significant refractive error occurred in 82-8% of the patients. (4) In all twins strabismus appeared at the same age in both twins, and t...

Background: Cerebral palsy is a condition usually associated with treatable ocular pathologies such as strabismus. Objectives: 1. To observe and estimate the prevalence of various types of strabismus in children with cerebral palsy 2. To estimate the strength of association between the presences of squint and birth weight, and squint and gestational age of the child. Materials and Methods: This...

BACKGROUND Childhood intermittent exotropia [X(T)] is a type of strabismus (squint) in which one eye deviates outward at times, usually when the child is tired. It may progress to a permanent squint, loss of stereovision and/or amblyopia (reduced vision). Treatment options for X(T) include eye patches, glasses, surgery and active monitoring. There is no consensus regarding how this condition sh...

One hundred and four children undergoing strabismus surgery were randomised post-operatively to one of three treatment groups; 1) fucithalmic drops twice daily; 2) chloramphenicol (chlormycetin) ointment twice daily; 3) no treatment. Allocation to the 'no treatment' group had to be stopped after 3 of the first 8 patients in the group developed severe mucopurulent conjunctivitis. A parental ques...

Forward-looking automotive radars can sense long-distant targets to enable early warning, but the lateral resolution is limited. Synthetic aperture radar (SAR) techniques achieve very high azimuth cannot resolve in forward direction. As a trade-off, squint-forward-looking SAR (SFL-SAR) perform 2D imaging on distant area squint moving direction, providing both and warning. In this paper, we anal...

This paper presents a new approach for the squint-mode spotlight SAR imaging. Like the frequency scaling algorithm, this method starts with the received signal dechirped in range. According to the geometry for the squint mode, the reference range of the dechirping function is defined as the range between the scene center and the synthetic aperture center. In our work, the residual video phase i...
