introduction: amblyopia is reduced vision in an eye that has not received adequate use during early childhood.  the most common cause of unilateral visual loss in children is amblyopia with prevalence rate of 1-4 percent in pre-school children . however, effective treatments may prevent intensive complication. this study was done to assess the treatment effects of amplyopia patients who have re...

V isual acuity is an important measure for assessment of visual function. While there are many charts available to test visual acuity, there is lack of consistency in the methods of testing and methods of reporting visual acuity that may make comparisons difficult between visual outcomes among different published studies. In our opinion, most US ophthalmologists are familiar with the Snellen no...

BACKGROUND Retinal vein occlusion is frequent cause of visual loss with insufficient treatment options. Many treatment options have been tried in the past including intravitreal triamcenoloneacetonide injection. This study was conducted to evaluate the efficacy and complications of intravitreal injection of Bevacizumab in different types of retinal vein occlusion. METHODS This interventional ...

purpose : to evaluate the visual results of amblyopic therapy in pediatric patients with monocular abnormalities. methods : the hospital records of visually immature patients with unilateral organic ocular abnormalities and decreased visual acuity, who presented to the pediatric ophthalmology clinic over a one year period, were reviewed. those who had 8 years old of age or less and underwent am...

In vision research, the Snellen chart is commonly used to assess visual acuity and is made up of letters of graduated sizes. By combining letter size and chart distance it is possible to determine the minimum visual angle of retinal resolution. A visual acuity of 20/30 means that at 20 feet the minimum angle of resolution is 30 20 -times the resolution standard (about 5 minutes of arc). The vis...

AIM To investigate whether retinal changes in children with severe malaria affect visual acuity 1 month after systemic recovery. METHODS All children with severe malaria admitted to a research ward in Malawi during one malaria season were examined by direct and indirect ophthalmoscopy. Visual acuity was tested in those attending follow up by Cardiff cards, Sheridan-Gardiner single letters, or...

Methods: Retrospective chart review of residentperformed phacoemulsification cases at the Atlanta Veterans Affairs Medical Center, Decatur, Georgia, from July 1, 1999, through June 30, 2002. Outcomes measured included postoperative uncorrected visual acuity (UCVA), best spectacle-corrected visual acuity (BSCVA), intraoperative complications, and adjusted phacoemulsification times (total phacoem...
