Four years after intraoperative floppy iris syndrome (IFIS) was first described,1 there is still no clear preference among ophthalmologists for the surgical management of these cases, according to a survey conducted last year by the ASCRS Cataract Clinical Committee.2 In fact, when asked to name their preferred single method for IFIS, the most common response (33%) was “always employ multiple s...

Cataract, a degradation of the optical quality of the crystalline lens, progressive and age-related, is the leading cause of treatable blindness worldwide. Cataract surgery is the most common surgical procedure performed by ophthalmologists and is the only effective treatment for cataracts. Advances in the surgical techniques and better postoperative visual outcomes have progressively changed t...

The dose-effect relationships of intraventricularly injected bradykinin, Gly-Arg-Met-Lys-bradykinin (GAML-bradykinin), synthetic substance P and angiotensin II on lever-lifting behavior of rabbits in a variable-interval (VI) 72-second schedule of sweetened water presentation were determined. All peptides used caused dose-dependent decreases in overall rates of VI responding during the experimen...

Case: A 26-year-old man referred to emergency service with coma, bradypnea (respiratory rate = 4 breaths per minute) and pinpoint pupil. On chest auscultation, diffuse coarse crackle and on abdominal auscultation, decrease of abdominal sounds were found. At first evaluation, pulse oximetry showed 19% saturation of oxygen. After oxygen therapy with facial mask and infusion of 8.4 mg naloxone in ...

conclusions this paper highlighted the need to exclude csd in children with unexplained symptoms such as prolonged fever, hepatosplenic lesion and osteomyelitis. case presentation we reported a series of seven children with unusual symptoms of csd. in particular, we described the case of a child with ptosis, miosis and enophtalmy, suggesting horner syndrome, associated with cervical lymphadenit...

We read the paper recently published by Markello et al. in the latest issue [1]. Analysis of our observations [2] together with a review of other cases [3,4] suggests that patients with the c.910CNT mutation in STIM1 gene (p.R304W) have the same heterogeneous disease and that Stormorken syndrome (StS) and York platelet syndrome (YPS) are probably two different names for the same clinical condit...

Eye exposure to the extremely toxic organophosphorus sarin results in long-term miosis and visual impairment. As current treatment using atropine or homatropine eye drops may lead to considerable visual side effects, alternative combined treatments of intramuscular (im) oximes (16.8 µmol/kg, im) with atropine (0.5 mg/kg, im) or with the short acting antimuscarinic tropicamide (0.5%; w/v) eye dr...

It has long been thought that the eyes index the inner workings of the mind. Consistent with this intuition, empirical research has demonstrated that pupils dilate as a consequence of attentional effort. Recently, Smallwood et al. (2011) demonstrated that pupil dilations not only provide an index of overall attentional effort, but are time-locked to stimulus changes during attention (but not du...
