A 65-year-old diabetic and hypertensive male presented with a sudden diminution of vision after sustaining a trivial fingernail injury to his only good-seeing (right) eye. The patient underwent phacotrabeculectomy with posterior chamber intraocular lens (PCIOL) implantation 22 years previously. In his right eye visual acuity at presentation was counting fingers at 1.5 m with an accurate project...

Purpose The aim of this study was twofold: first, to evaluate the predisposing factors for occurrence of malignant glaucoma and second, to compare frequency of malignant glaucoma depending on the type of primary glaucoma surgery. Methods Retrospective analysis was performed in 1689 consecutive patients who underwent glaucoma surgery alone or combined with phacoemulsification. Data collected i...

OBJECTIVE To compare the outcome of phacoviscocanalostomy in pseudoexfoliation glaucoma (PEXG) versus that in primary open-angle glaucoma (POAG). DESIGN Prospective comparative study. PARTICIPANTS Sixty eyes of 60 patients who underwent phacoviscocanalostomy for cataract and medically uncontrolled PEXG (30 eyes) or POAG (30 eyes). METHODS Success rate was based on intraocular pressure (IO...

PURPOSE Coexisting pseudoexfoliation glaucoma (PEXG) and cataract represents a special challenge. Although phacotrabeculectomy is an effective procedure, it combines the risks of phacoemulsification and trabeculectomy. This study evaluates phacoviscocanalostomy to manage eyes with PEXG and cataract. METHODS We conducted a prospective noncomparative study that included 30 consecutive eyes of 2...

UNLABELLED Cataract surgery has been demonstrated to lower intraocular pressure (IOP) in eyes with glaucoma. The evidence is strong in angle-closure patients that cataract surgery improves IOP and dramatically reduces the future risk for IOP spikes and acute attacks. Randomized controlled trials (RCTs) have shown that cataract surgery may be preferable to laser iridotomy or phacotrabeculectomy....

background: research project risks are uncertain contingent events or situations that, if transpire, will have positive or negative effects on objectives of a project. the management of health and safety at work (mhsw) regulations 1999 require all employers and the self-employed persons to assess the risks from their work on anyone who may be affected by their activities. risk assessment is the...

background & aims of the study: leachate production is a major problem for solid waste landfills and causes important threat to health public and environment. one of the typical properties of heavy metals is that they cannot easily decompose in the environment. the aim of this study was to measure of heavy metals concentrations in old-age leachate from qazvin landfill site, iran. materials & me...

background surgical site infections (ssis) are the most common nosocomial infections in surgical patients. depending on the source of a traumatic wound, particular pathogens are expected to be present while their prevalence varies in different conditions. this study focused on determination of microorganisms in traumatic wound infection and the frequency of staphylococcus aureus and other organ...

background: mosquitoes lay eggs in a wide range of habitats with different physicochemical parameters. ecological data, including physicochemical factors of oviposition sites, play an important role in integrated vector management. those data help the managers to make the best decision in controlling the aquatic stages of vectors especially using source reduction. methods: to study some physico...
