Aims: To ascertain whether measurement of the vitreous fluid levels of vascular endothelial growth factor (VEGF) or angiotensin II (Ang II) could predict the outcome of vitreous surgery in patients with proliferative diabetic retinopathy (PDR). Methods: A prospective observational case study was performed in 61 consecutive patients (61 eyes) with PDR who underwent vitreoretinal surgery. Vitreou...

For eyes with diabetic retinopathy which require vitreous surgery and pan-retinal photocoagulation (PRP), pre-treatment of PRP before vitreous surgery reduce the activity of diabetic retinopathy, however sometimes cause macular edema leading to visual disturbance. Some cytokines in the vitreous increase in eyes with diabetic macular edema, thus the relationship between PRP and vitreous cytokine...

Introduction Microincision of the cystic duct and its confluence part, which facilitated application transcystic-laparoscopic common bile (CBD) exploration (transcystic-LCBDE), had been described in some reports. However, it is unclear whether transcystic-LCBDE with microincision (micro-LCBDE) effective safe as transductal-LCBDE for failed patients choledocholithiasis. Methods In this retrospec...

purpose : to compare the outcomes of coaxial microincision phacoemulsification with that of conventional coaxial phacoemulsification setting: department of ophthalmology, farabi and noor eye hospitals, tehran, iran methods : in a prospective study, 74 eyes of 74 patients with cataract were randomly selected to have cataract extraction using 1 of 2 techniques: coaxial microincision phacoemulsifi...

The symptoms of idiopathic epiretinal membranes (ERM) of the macula are blurred vision caused by the retinal dysfunction including photoreceptor dysfunction and metamorphopsia caused by retinal distortion. Surgical removal of ERM is reportedly associated with few complications, and surgical results are generally good [15]. Furthermore, we reported treating ERM and internal limiting membrane (IL...

BACKGROUND To report our findings in a patient with asteroid hyalosis (AH) who had a severe reduction of his visual acuity following cataract surgery. The vision was improved by vitreous surgery. CASE PRESENTATION The patient was an 81-year-old man. Following cataract surgery on his left eye, his decimal best-corrected visual acuity (BCVA) was markedly reduced from 0.2 to 0.02. A large number...

OBJECTIVE To reduce the surgical risks to patients and expose surgeons to surgical experience and complications, we have developed a practical system of vitreous surgery using virtual-reality technology. METHODS The system is composed of high-resolution color stereo binoculars, haptic devices, foot switches, and a high-speed graphics computer. To simulate vitreous surgery, we created several ...

purpose : to determine the incidence and determinants of intraoperative complications of cataract surgeries performed in iran during 2000 to 2005 methods : the iranian cataract surgery survey (icss) is a retrospective study in which random sampling was done from selected centers. one week per season between 2000 and 2005 was assigned to each center and records of cataract surgeries performed du...
