Purpose of this study is to compare the ocular functional changes including pupil size, visual acuity, depth of focus, accommodative amplitude, visual field, contrast sensitivity, and ster...
This study is designed to evaluate the effectiveness of a novel amblyopia treatment - Intermittent occlusion therapy (IO-therapy) glasses (AmblyzTM) in treating severe amblyopia. Children...
This project is designed to test a lightweight, portable, computerized pair of glasses that will help reduce some of the cognitive deficits seen in patients who have suffered damage to the...
Non-pharmacological interventional pilot study on the effect of prismatic glasses for the improvement of Pisa syndrome in Parkinson's disease. The study involves 40 patients, of whom 20 r...
This study is designed to answer the question: What if the Intermittent Occlusion (IO-therapy) glasses were prescribed all day (12-hours) in which the total time of treatment only took 4 w...
Liquid crystal glasses use an intermittent occlusion technique and may improve compliance compared to adhesive patches. Previous studies support the effectiveness of intermittent occlusion therapy (IO...
The aim of the study was to estimate occupational radiation dose to the eye lens of radiologists and the dose reduction ratio of lead glasses during interventional radiology. Three interventional radi...
Most radiation protection items made from modern lead contain 210Pb. This study estimated the impact on eye lens of radiation derived from the 210Pb in three types of radiation protection glasses. The...
The reduction in the occupational dose limit of the eye lens has created the need for optimizing eye protection and dose assessment, in particular for interventional clinicians. Lead glasses are one o...
To assess the patterns and predictors of glasses wear in a 2-year school-based study.
A pair of ophthalmic lenses in a frame or mounting which is supported by the nose and ears. The purpose is to aid or improve vision. It does not include goggles or nonprescription sun glasses for which EYE PROTECTIVE DEVICES is available.
The professional practice of primary eye and vision care that includes the measurement of visual refractive power and the correction of visual defects with lenses or glasses.
Qualified professionals trained in primary eye and vision care, including measurement of visual abilities, diagnosing disorders of the visual system and provision of treatment such as prescriptions for correction of visual defects with lenses or glasses and vision therapy.
A ready-made or custom-made prosthesis of glass or plastic shaped and colored to resemble the anterior portion of a normal eye and used for cosmetic reasons. It is attached to the anterior portion of an orbital implant (ORBITAL IMPLANTS) which is placed in the socket of an enucleated or eviscerated eye. (From Dorland, 28th ed)
A variation of the PCR technique in which cDNA is made from RNA via reverse transcription. The resultant cDNA is then amplified using standard PCR protocols.
