The induction of acute reversible lens opacities in the Stjrian hamster following phenylephrine mydriasis is accompanied by an increase in the sodium and potassium concentration and a decrease in the water content of the lens. There is a simultaneous increase in sodium concentration in the aqueous humor. Final analysis of the effect of various drugs on these lens opacities should reveal that th...

AIM To investigate the effect that squint surgery has on pupillary diameter. METHODS The effect of squint surgery on pupil size was investigated in 19 patients. RESULTS A significant mydriasis in the operated eye was observed when compared with the unoperated eye. This was independent of the number or type of extraocular muscles operated upon. CONCLUSION It is hypothesised that this chang...

We present the CT and MR imaging findings in acute methanol intoxication in a 35-year-old man who was admitted to the emergency department with weakness, blurred vision, mild bilateral areactive mydriasis, and a progressive decrease in the level of consciousness. CT and MR imaging showed bilateral putaminal hemorrhagic necrosis and subcortical white matter lesions with peripheral contrast enhan...

Pseudoexfoliation (PXF) syndrome is a well-recognized clinical entity of considerable clinical significance. It is associated with poor mydriasis, cataracts with weak zonular support, secondary glaucoma and possibly with biochemical abnormalities, such as elevated homocysteine and systemic diseases involving the cardiovascular and central nervous system. There have also been some recent studies...

As a new ophthalmic non-steroidal anti-inflammatory drug (NSAID) with prodrug structure, Nepafenac was supposed to have a better efficacy than conventional NSAIDs both in patients' tolerability and ocular inflammation associated with cataract surgery. However, many current studies reached contradictory conclusions on the superiority of Nepafenac over Ketorolac. The objective of our study is to ...

Children's instrumental helping has sometimes been interpreted as a desire to complete action sequences or to restore the physical order of things. Two-year-old children (n = 51) selectively retrieved for an adult the object he needed rather than one he did not (but which equally served to restore the previous order of things), and those with greater internal arousal (i.e., pupil dilation) were...
