Filter by:Intraocular surgery could induce vitreous degeneration and posterior vitreous detachment (PVD). Vitreomacular interface (VMI) abnormalities usually are caused by abnormal PVD, vitreoschisis and partial-thickness PVD. Furthermore, the PVD could induce the peripheral break. The incidence of peripheral break and epimacular membrane (EMM) after pneumatic retinopexy were 11.7% and 4-11%, respectively. Although multiple intravitreal anti-vascular endothelial growth factor (anti-VEGF) injections induced PVD of 5.6%, but peripheral break was reported as only 0.67%. The most common intraocular surgery is cataract surgery. From the literature review, many methods were used to detect the PVD after phacoemulsification. The former studies used indirect ophthalmoscopy and ocular ultrasound for diagnosis of PVD. The later studies used the optical coherence tomography (OCT) for PVD detection. The OCT device had higher effectiveness in evaluation of the posterior segment, then it can detect post-phacoemulsification PVD more and early than previous studies. Ivastinovic et al demonstrated 59.2% of patients had PVD at 1 month after phacoemulsification, and increased up to 71.4% at 3 months. The incidence of rhegmatogenous retinal detachment (RRD) after phacoemulsification is gradually increased with time. The accumulative risk of RRD was increased from 0.27% at 1 year to 1.27% at 20 years after phacoemulsification.
Study of novel surgical technic-suprachoroidal buckling for therapy of rhegmatogenous retinal detachment.It was excpted to reattached the retina and improve visual function of rhegmatogenous retinal detachment patients.
The purpose of this study is to compare the efficacy of oral sedation to intravenous sedation with anesthesiology support and monitoring.
Lumbopelvic fixation is the treatment opation for spinopelvic dissociation. In our study we will compare unilateral versus bilateral lumbopelvic fixation as regarding functional outcomes by Majeed score along a period of 12vmonths as a primary measure and metal failure,skin condition and nonunion as secondaries.
