PURPOSE To determine the incidence of and risk factors for posterior capsule rupture and vitreous loss during phacoemulsification performed by ophthalmology residents. SETTING Academic ophthalmology resident training center, Tehran, Iran. DESIGN Cross-sectional study. METHODS This study included patients who had phacoemulsification by ophthalmology residents from August 2010 to August 201...

After chorioretinal biopsy in dogs, obtained without vitreous loss, accessory glial cells and fibroblasts filled the defect between cortical vitreous and bare sclera. The proliferating glial cells laid down a new basement membrane which was complete both on the internal and external aspects of the defect. After biopsy complicated by vitreous loss, however, cellular proliferation failed to re-es...

OBJECTIVE To evaluate vitreous glutamate concentration and axon loss in monkeys with experimental glaucoma. METHODS We induced unilateral chronic glaucoma by means of laser trabecular destruction in 14 rhesus and 6 cynomolgus monkeys. Intraocular pressure (IOP) was monitored weekly. We assessed optic nerve damage clinically and photographically. Vitreous, sampled immediately before enucleatio...

Vitreous loss is a serious complication of cataract surgery. Following vitreous loss it is common practice to perform a primary implantation of an anterior chamber lens (AC-IOL). We retrospectively analysed 642 consecutive cases of cataract extraction performed between 1983 and 1986 with special attention to those patients in whom vitreous loss occurred and an AC-IOL was placed. There were 27 s...

With up to 6% of cataract surgeries complicated by vitreous loss,1 anterior vitrectomy is an essential skill of today’s cataract surgeon. Although the incidence of this complication is predictably higher in patients with complex cataracts due to pseudoexfoliation, intraoperative floppy iris syndrome, or posterior polar or dense cataracts, vitreous loss can occur unexpectedly in any case. To dec...

PURPOSE To compare the vitreous loss complication rate of manual phacoemulsification cataract surgery with that of femtosecond laser-assisted cataract surgery. SETTING Mercy Eye Specialists, Springfield, Missouri, USA. DESIGN Retrospective single-center case series. METHODS Cataract surgeries from 2010 to 2014 performed by 4 surgeons were audited for rates of vitreous loss. Vitreous loss ...

Ethanol concentrations in postmortem blood and vitreous humor samples collected at the Miami-Dade Medical Examiner Department over 5-6 years ago were reexamined to assess whether vitreous humor is a more reliable specimen for the analysis of ethanol in samples stored long term. The average change in 50-mL polypropylene tubes containing blood was 0.06 gm/dL (35% loss). On the other hand, vitreou...

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...
