PURPOSE To investigate changes of crystalline lens position during accommodation in children with emmetropia, myopia, and hyperopia. METHODS A total of 188 children (372 eyes) from 4 to 19 years old (mean age 11.3+/-4.43) with cycloplegic refractive error within a range +9.00 D to -9.00 D were enrolled. After a general ophthalmic examination, ultrasound biometry was performed, with the eye at...

AIM To compare the mydriatic efficacy of an ophthalmic insert (Mydriasert, MY) versus phenylephrine and tropicamide (PT) eye drops. METHODS Two controlled, prospective, randomized, single-blind studies were performed. In the first study, a total of 80 eyes from 40 outpatient-clinic patients were analyzed. PT drops were applied to the right eye, and a MY device was inserted in the left eye for...

AIMS To examine the effects of pupil dilatation on driving performance and determine whether this was related to changes in standard measures of visual function. METHODS The driving and vision performance of 16 young, visually normal participants was measured with both normal and dilated pupils. Pupils were dilated with 1% tropicamide. Driving performance was measured under daytime conditions...

PURPOSE To study the relationship between exophthalmometric value (EV) and refractive error in Cameroonian young adults. PATIENTS AND METHODS A prospective descriptive study was carried out in the ophthalmic unit of the Yaoundé Central Hospital from March to May 2015. Consenting patients aged 20-40 years with no intraocular pathology who were seen for refractive errors were included. Ocular p...

The aim of the present study was to investigate the incidence of fungal and bacterial contaminations of in-use eye drop products in the teaching department of ophthalmology, Imam Khomeini Hospital, Ahvaz. Two hundred and eighty seven eye drop bottles were randomly collected at the end of day 1, day 2, day 3, day 4 and day 7 of use. The eye drop residues, swabs from internal caps and droppers we...

PURPOSE: To assess the effect of change in pupU dianww induced by Tropicamide 0.5% on Snellen acuity and lclrcr cotmast senskivhy tn humans. METHODS: 20 eyes were ~sscssed wth the l'clli-Robson CS char1 and Sncllen chart pn-and posr-dilataGon (Tropicamide O.S%), with luminance kept at between ICUI and 1100 111x. RESULTS: Pupil dilatsdon was found to have lirde effect on SneUcn acuity: 13 eyes m...

The paper derives the optimal organizational response of a bank (the principal) which faces a risk of collusion between the credit manager (the agent) and the credit-seeking firms. The bank can deter collusion either through internal incentives or by distorting the credit contracts. The model thus explicitly takes into account the interaction between internal (collusion) risks and external (def...
