Cataract is the leading cause of blindness worldwide. Fortunately, cataract-induced blindness is reversible by cataract surgery. In addition to reclaiming lost vision, cataract surgery lowers intraocular pressure, but the reason for this remains unclear. Understanding the mechanism behind intraocular pressure reduction following cataract surgery has implication for treating glaucoma, which invo...

purpose: to evaluate the effect of intravitreal bevacizumab (ivb) injection on sustained intraocular pressure (iop) methods: this non-randomized prospective study was conducted on 359 eyes of 359 patients in amir almomenin (rasht) and labbafinejad (tehran) hospitals. after history taking and complete ocular examination, iop was measured one week and one day before injection (twice at each sessi...

purpose : to investigate intraocular pressure (iop) changes due to different serum level heights by using tonopen in acquired globes from the iran eye bank (ieb). methods : in this interventional prospective case series, serum were infused into 18 normal globes acquired from ieb by using 21g needle inserted in vitreal space through optic nerve head to change the iop by different fluid level hei...

the aim of this study was to determine the combination effect of latanoprost and pilocarpine on theintraocular pressure and pupil size in normal rabbits. in this study, 18 rabbits were randomized to threegroups of 6 animals each. the right eyes of rabbits in group 1 were treated topically with latanoprost, ingroup 2 with pilocarpine and in group 3 with latanoprost and pilocarpine. the left eyes...

purpose : cataract surgery is the most common ocular surgery worldwide and in modern era of phacoemulsification with posterior chamber intraocular lens (pc iol) implantation, refractive aspects of surgery is as important as the surgery itself. after the iol implantation, the anterior chamber depth (acd) is increased and the iridiocorneal angle is widened. these changes should be considered for ...

In our long term evaluation of patients with Hansen's disease we have frequently found reduction of their intraocular pressure. Furthermore, we noted changes in their intraocular pressure on change of posture. To determine if these changes have any significance we measured the intraocular pressures of 24 experimentally infected and 39 control monkeys in both sitting and reclining positions. We ...

INTRODUCTION Any factor causing constriction of the neck may lead to an increase in intraocular pressure. A tight necktie may result in increasing intraocular pressure, which could lead to an erroneous diagnosis and treatment of ocular hypertension or even glaucoma. This study was aimed at evaluating the effect of a tight necktie on intraocular pressure measurement using Goldmann applanation to...

purpose: to evaluate the predictability, efficacy, and safety of iris-claw artisanô phakic intraocular lenses ­for myopia. methods: through a prospective clinical study, 35 eyes of 21 patients with myopia from -5 to 26.5 diopters underwent implantation of the artisan lens. patients were examined 1, 3, and 7 days (all eyes); 1 month (28 eyes), 3 months (29 eyes), and 6 months (32 eyes) after the...

purpose: to describe a case with a rare complication of posterior chamber intraocular lens (pc-iol) implantation in a patient who had undergone extracapsular cataract extraction (ecce) two years before case report: a 80-year-old diabetic woman presented with an exposed pc-iol in her left eye with a history of mechanical trauma. slit-lamp examination revealed an extruded pc-iol lied on the anter...
