orbital fat adherence syndrome is a known complication of strabismus, orbital and scleral buckling surgery or orbital trauma which induces a restrictive strabismus. in this case presentation we introduce a surgical method of globe slinging using temporalis fascia for correction of restrictive esotropia due to fat adherence syndrome. in our review of literature we found no report of a similar pr...

Abstract Experiments and first-principles calculations were performed to investigate the effects of Cu substitution in CH 3 NH PbI perovskite crystals. The indicated that energy level d orbital formed above VB maximum would be an acceptor or defect level. effect addition on device properties was investigated, with added 2% provided higher efficiencies than standard device. On other hand, decrea...
