one of the dangerous complications of cataract extractions is vitreous loss. the purpose of this stuy is to evaluate the incidence of vitreous loss and its sepuale while teaching residents at rasoul akram hospital in iran. this study has been conducted on existing records of 730 eyes which were subjectd to extracapsular cataract extractions by 3rd and 4th year, right handed resident of rasoul a...

purpose: to compare the visual outcomes and complications of phacoemulsification surgery in patients with and without vitreous loss (vl). methods: a historical cohort study was performed on patients attending labbafinejad hospital who had underwent phacoemulsification surgery and was complicated by vl from april 2006 to march 2007. a control group was selected randomly from patients with uncomp...

purpose: to report the rate of vitreous loss during phacoemulsification and its contributing risk factors in patients operated on at labbafinejad medical center.  methods: this prospective comparative descriptive study included patients with cataract undergoing phacoemulsification by ophthalmology residents or cornea fellows from november 2006 to november 2007. all patients underwent a complete...

Retrobulbar anaesthesia, digital massage, osmotic therapy, and acetazolamide are frequently employed in various combinations to effect ocular hypotony before cataract extraction.* It is believed by many that hypotony prevents vitreous loss during this operation. t Profound akinesia to preclude extraocular muscle contraction and resulting shortening of the scleral shell is a clinically accepted ...

The transport of fluorescein monoglucuronide, a fluorescent metabolite of fluorescein, from the vitreous was studied. Ten microliter of 1 mM fluorescein monoglucuronide or fluorescein solution was injected into the rabbit vitreous body, and the vitreous concentration was measured every 2 hr. The rate of loss from the vitreous was 0.066 +/- 0.012 (SD)/hour for fluorescein monoglucuronide and 0.2...

PURPOSE To determine the rate and risk factors of vitreous loss during phacoemulsification in patients with cataracts operated by ophthalmology residents and fellows at Labbafinejad Medical Center. METHODS This prospective descriptive study included consecutive patients with cataracts undergoing phacoemulsification over a one year period. All patients were operated under local or general anes...

OBJECTIVES To assess the resident's phacoemulsification learning curve as a risk factor for vitreous loss and to determine the incidence of vitreous loss among the residents performing phacoemulsification. DESIGN Retrospective matched case-control study MATERIAL AND METHOD A case-control study comparing all consecutive cases of attempted phacoemulsification with intraocular lens (IOL) impla...

PURPOSE To explore the attachments of the posterior zonule and vitreous in relation to accommodation and presbyopia in monkeys and humans. METHODS Novel scanning electron microscopy (SEM) and ultrasound biomicroscopy (UBM) techniques were used to visualize the anterior, intermediate, and posterior vitreous zonule and their connections to the ciliary body, vitreous membrane, lens capsule, and ...

PURPOSE To compare the complication rate of posterior capsule rupture (PCR) with vitreous loss during phacoemulsification at an ambulatory surgical center with published results as a clinical audit for quality control. METHODS A retrospective chart review of 3,339 consecutive patients who underwent routine phacoemulsification by four experienced private practice surgeons from January 1, 2011 ...
