An earlier report describing a lack of compensation to imposed myopic and hyperopic defocus in chicks reared in UV lighting has led to the belief that the spatial resolving power of the UV cone photoreceptor network in chicks is not capable of decoding optical defocus. However this study used dim light rearing conditions, of less than 10 lx. The purpose of the current study was to determine if ...

purpose: to study the distribution of ocular higher-order aberrations (hoas) and mesopic pupil size in individuals screened for refractive surgery. methods: ocular hoas and mesopic pupil size were studied in 2458 eyes of 1240 patients with myopia, simple myopic astigmatism and compound myopic astigmatism and 215 eyes of 110 patients with hyperopia, simple hyperopic astigmatism and compound hype...

purpose: to examine the relationship between retinal nerve fiber layer (rnfl) measurements obtained using scanning laser polarimetry with variable corneal compensation (vcc) and central corneal thickness (cct) measurements using pentacam in myopic patients methods: the study included 45 eyes from 45 myopic patients with intraocular pressure (iop) measurements≤21 mmhg. all participants had norma...

In this paper we reexamine several experimental papers on myopic loss aversion by analyzing individual rather than aggregate choice patterns. We find that the behavior of the majority of subjects is inconsistent with the hypothesis of myopic loss aversion.

PURPOSE To group eyes in our refractive surgery unit on the basis of the origin of their ametropia and to assess the percentage of eyes in the different groups. METHODS Refractive parameters and the axial eye length (AL) of 131 eyes of 131 persons with different refraction were measured. The eyes were initially classified into five groups on the basis of the grade of their ametropia: hypermet...

OBJECTIVE To determine whether bifocal and prismatic bifocal spectacles could control myopia in children with high rates of myopic progression. METHODS This was a randomized controlled clinical trial. One hundred thirty-five (73 girls and 62 boys) myopic Chinese Canadian children (myopia of > or =1.00 diopters [D]) with myopic progression of at least 0.50 D in the preceding year were randomly...

We report seven cases of subretinal neovascularisation with inferior posterior staphyloma. The upper border of the shallow staphyloma, detected by B-mode echography, invaded the macular area, and there was a neovascular net at the edge of the staphyloma. Three of the cases showed chorioretinal atrophy at the upper edge of the staphyloma in the same location as the neovascular net. Our cases wer...

PURPOSE The study was performed to establish the relationship between the slope of the accommodative response function and refractive error in children. METHODS Using an autorefractor, accommodative responses were measured in children under the following conditions. The subjects wore their best subjective refraction to view targets (a 3 x 3 array of 20/100 letters) displayed at seven distance...

Myopic loss aversion was suggested by Benartzi and Thaler (1995) as the main explanation for the equity premium puzzle. We investigate the impact of myopic loss aversion on actual investment decisions of 400 Dutch individual investors, covered by the Dutch National Bank Household Survey. We find that higher loss aversion is associated with a lower share of investments in risky assets. The inves...
