Recognizing imaging characteristics after ophthalmic surgery is necessary for radiologists to prevent misdiagnosis. We review typical appearances of intraorbital implanted devices and materials on CT and MRI with demonstration of the common surgical procedures. EX-PRESS glaucoma filtration devices appear as punctate areas of metal attenuation on CT and are typically placed at the corneoscleral junction. The imaging manifestations after cataract extraction are absence of the native lens of ovoid mass and the intraocular lens with high attenuation on CT and low signal intensity on MRI...

BACKGROUND: Refraction change of silicone oil (SO) tamponade in phakic and aphakic eye has been studied thoroughly; however, it is rarely studied in pseudophakic eye. In this paper we aimed to deduce a theoretical formula predicting refractive shift of silicone oil tamponade in pseudophakic eye and compared it with clinical findings. METHOD: A theoretical formula was deduced through strict geometric optical principles under the Helmholtz Schematic eye model. Pre/postoperative refractive status of patients who previously underwent phacoemulsification, intraocular lens (IOL) implant, vitrectomy, SO tamponade and required SO extraction was studied...

Purpose. To analyze the safety, effectiveness, and stability of triplex surgery for phakic 6H anterior chamber phakic intraocular lens explantation and phacoemulsification with in-the-bag IOL implantation for super high myopia in long-term observations. Methods. This retrospective case series evaluated 16 eyes of 10 patients who underwent triplex surgery. Best corrected visual acuity (BCVA), endothelial cell density (ECD), and associated adverse events were evaluated. Results. The mean follow-up time after the triplex surgery was 46 ± 14 months...

AIM: to evaluate the accuracy of different modified methods for axial length (AL) measurement in silicone-filled eyes. MATERIAL AND METHODS: The study was conducted in a group of 60 patients (60 eyes) with silicone oil tamponade (Oxane 1300 cst). Axial length measurements were taken using IOL Master optical coherence biometry ('silicone-filled eye' mode) and modified A-scan ultrasound biometry (velocity of ultrasound passing through the vitreous body set at 980 m/s and 1000 m/s)...

AIMS: To evaluate the incidence of and factors contributing to intraoperative and postoperative complications of eyes with previous pars plana vitrectomy (PPV) undergoing phacoemulsification and intraocular lens (IOL) implantation for cataract. METHODS: The intraoperative and postoperative complications and observations in 513 eyes of 485 patients with previous PPV undergoing sutured and sutureless cataract surgery were assessed. Associations between preoperative characteristics and complications during and after the surgery were explored...

BACKGROUND: Open globe injuries complicated with the presence of an intraocular foreign body constitute a vision threatening condition. PURPOSE: To present the results of pars plana vitrectomy in patients with intraocular foreign body. MATERIAL AND METHODS: Medical records of 22 patients were analyzed. Retrospective analysis of data included visual acuity, age, gender and type of injury. RESULTS: All patients were men and the mean age was 37 years...

PURPOSE: To evaluate the surgical approach of pars plana vitrectomy combined with 360° retinotomy and silicon oil tamponade in the treatment of patients with large subretinal hemorrhage. METHODS: Prospective, nonrandomized, and noncomparative case series study. Consecutive patients with breakthrough vitreous hemorrhage and massive subretinal hemorrahge were recruited to have combined surgery of pars plana vitrectomy with 360° retinotomy and silicone oil temponade...

INTRODUCTION: Penetrating wounds with intraocular foreign body are ophthalmologic emergencies due to their severity and complexity and may require multiple surgeries for final resolution. CASE REPORT: 30-years-old patient with penetrating wound and metallic intraocular foreign body in the posterior vitreous requires successive operations for IOFB extraction, lensectomy, posterior vitrectomy for rhegmatogenous retinal detachment and then silicone oil extraction with final visual acuity 0, 4 PH...

PURPOSE: To report a retrospective series of seven phakic eyes of seven patients suffering from a malignant glaucoma-like syndrome following pars plana vitrectomy and silicone oil (SO) injection. MATERIALS AND METHODS: Seven eyes with retinal detachment treated with pars plana vitrectomy with or without scleral buckling with SO tamponade. This was followed by cataract extraction to manage the elevated intraocular pressure (IOP). RESULTS: This was a retrospective review of seven cases that received pars plana vitrectomy and SO with or without scleral buckling for different causes of retinal detachment (three were rhegmatogenous and four were tractional)...

PURPOSE: Open globe eye injuries can have profound social and economic consequences. Here, we describe two cases of war and outdoor activity open globe eye injury where, despite a low OTS score, current microsurgical technology allowed for a favorable outcome. CASE REPORT 1: A 33-year-old Libyan soldier had been treated for an open-globe grenade blast trauma to his left eye, which showed light perception and OTS score 2. He had undergone a lensectomy and PPV with silicone oil tamponade...

There was made an aberrometry of new IOL with changeable refractive surface. Different power of silicon oil inside the lens become changes in it refractive power. So, in this way we made three types of IOL refractive power: 17,5 D; 20 D; 22 D. The quality of experimental optical system may be comparative with optical system that made by ReSTOR IOL implantation in human eye. HOA and LOA, that generated by the new IOL, had no or small influence to the quality of optical system.

We present a patient with Duchenne muscular dystrophy who developed severe proliferative retinopathy for which vitrectomy was successfully performed in one eye. METHOD: Case presentation. A 23-year-old Japanese man with Duchenne muscular dystrophy complicated by cardiac and respiratory insufficiency had reduced vision in both eyes. His best-corrected visual acuity was 0...

The article presents the aberrometry results of a new intraocular lens (IOL) model with variable refractive surface of own design. By changing the pressure of silicone oil inside the artificial lens three levels of refractive power were achieved: 17.5D; 20.0D; 22.0D. The quality of the experimental optical system is comparable to that of a human eye after in vivo implantation of a ReSTOR multifocal IOL. Accommodating IOLs with refractive power varying within 4.5D are capable of maintaining the quality of retinal image, thus, ensuring high visual acuity...
