In four experiments, we tested the existence of an ideal facial feature arrangement that could optimize the attractiveness of any face given its facial features. Participants made paired comparisons of attractiveness between faces with identical facial features but different eye-mouth distances and different interocular distances. We found that although different faces have varying attractivene...

PURPOSE To measure histomorphometrically the location of the peripapillary arterial circle of Zinn-Haller (ZHAC) and assess its associations with axial length. METHODS Using a light microscope, we measured the distance from the ZHAC to the peripapillary ring (optic disc border), the merging point of the dura mater with the posterior sclera ("dura-sclera point"), and the inner scleral surface....

OBJECTIVE To assess whether there is any difference in the oscillation of the plantar pressure center in single-leg stance between athletes and non-athletes with and without ankle sprains. METHODS 54 volunteers performed four static assessments and one dynamic assessment while standing on one foot on a baropodometer, barefoot, for 10 s in each test. The variables of area (cm(2)), distance (cm...

PURPOSE To study the effect of pupil size on the relationship between refractive astigmatism and uncorrected distance visual acuity (UDVA) and pseudoaccommodation in pseudophakic eyes. METHODS Thirty-six eyes from 36 patients who underwent phacoemulsification and intraocular lens (IOL) implantation were included. All eyes were divided into two groups based on the presence of postoperative-wit...

AIM To evaluate the acceptability, effectivity, and side effects of a monovision spectacle correction designed to reduce accommodation and myopia progression in schoolchildren. METHODS Dominant eyes of 11 year old children with myopia (-1.00 to -3.00 D mean spherical equivalent) were corrected for distance; fellow eyes were uncorrected or corrected to keep the refractive imbalance <or=2.00 D....

OBJECTIVE To determine the effectiveness of vestibular-specific neuromuscular training on motor skills, balance and health-related quality of life in children with hearing impairment. DESIGN Controlled, randomized, preliminary study. SETTING Rehabilitation school for children with hearing impairment. SUBJECTS AND INTERVENTION Twenty-three children with mean age of 7.5-8.1 years with heari...

BACKGROUND This paper presents the results over a 2-year follow-up of the first human trial of photorefractive keratectomy (PRK) for correction of hyperopia using an erodible disc excimer laser delivery system (Summit) coupled to an axicon lens. METHODS We treated 25 eyes of 21 patients for a mean correction of +3.38 +/- 0.97 D (range, +1.00 to +4.00 D). The hyperopic correction was made usin...

PURPOSE To evaluate the outcomes of phacoemulsification with binocular implantation of SA-40N multifocal intraocular lens at the "Hospital de Olhos de Minas Gerais". METHODS The charts of 58 patients (116 eyes) who were submitted to phacoemulsification with binocular implantation of SA-40N multifocal intraocular lens were retrospectively analyzed. RESULTS The mean preoperative spherical equ...

3D technology is broadly divided in to reconstructing 3D images (3DI) from given 2D images (2DI) and 3D visualization (3DV) using stereo pairs (SP). Literature Review revealed that many satisfactory techniques were developed for reconstructing 3DI from given 2DI and a reasonably good 3D reconstruction is possible. When a stereopair is viewed through a slot no attachments are needed as the basic...

PURPOSE To perform a comparative clinical analysis of the safety, efficacy, and predictability of two surgical procedures (ie, small incision lenticule extraction [SMILE] and femtosecond laser-assisted LASIK [FS-LASIK]) to correct myopia. METHODS Sixty eyes of 31 patients with a mean spherical equivalent of -5.13 ± 1.75 diopters underwent myopia correction with the SMILE procedure. Fifty-one ...
