purpose: to evaluate the underlying causes of rhegmatogenous retinal detachment (rrd) in eyes operated for this reasion. methods: out of 1473 patients who underwent retinal detachment surgery, records of 369 patients were randomly selected and evaluated for the types of retinal breaks, the underlying disorders, and location of breaks. results: fifty-two percents of patients were less than 50 ye...

We present a methodology to derive the growth history of a fault-tip fold above a basal detachment. Our approach is based on modeling of the stratigraphic and geomorphic records of deformation, as well as the finite structure of the fold constrained from seismic profiles. We parametrize the spatial deformation pattern using a simple formulation of the displacement field derived from sandbox exp...

PURPOSE To evaluate the causes of retinal detachment after silicone oil removal, to define possible risk factors and the anatomical and functional prognosis of this complication. METHODS 112 eyes that underwent silicone oil removal were included. The group of eyes with retinal detachment after oil removal (18/112 eyes, 16.1%) was compared with the group with no postoperative retinal detachmen...

A series of 54 non-myopic aphakic eyes with no signs of posterior vitreous detachment and 63 non-myopic aphakic eyes with various stages of posterior vitreous detachment was followed-up for a period of 6 months to 6 years. Over half of the eyes with no vitreous detachment when first examined developed various stages of posterior vitreous detachment during the follow-up period; in 10 eyes this w...

The Dayingezhuang orogenic gold deposit, located in the northwestern Jiaodong Peninsula, is hosted by Zhaoping detachment fault, but paleostress regime during mineralization period remains poorly understood. In this study, a series of numerical modeling experiments with variable stress conditions were carried out using FLAC3D software to determine orientation and fluid migration processes ore-f...
