Comparison of Aflibercept Ranibizumab and Bevacizumab in Treatment of Retinopathy of Prematurity

ABSTRACT Purpose: To evaluate and to compare efficacy of three anti vegf drugs (afibercept, ranibizumab and bevacizumab) in treatment of retinopathy of prematurity(ROP). Method: 228 eyes of 147 patients with type 1 ROP who received anti-vascular endothelial growth factor (anti-VEGF) intravitreal injections between August 2013 and February 2016 were retrospectively evaluated. One hundred twenty four eyes of 81 patients received 0.25 mg...

Effect of Macula Development on Refraction in Infants Screened and Treated Due to Premature Retinopathy

ABSTRACT Purpose: The purpose of this study was to determine the effect of macula edema detected at premature stage with optical coherence tomography on refraction at age 1, 2 and 3. Material & Method: 217 eyes from 217 infants who underwent optical coherence tomography at premature stage were included in the study. Edema detected with optical coherence tomography was divided into three groups as no edema, Type A edema that does not...

A New Method: Transpalpebral Illumination for Wide Angle Fundus Imaging in Retinopathy of Prematurity Without Pupil Dilatation

ABSTRACT Background: Fundus imaging is very important for screening of retinopathy of prematurity (ROP). Available methods need pupil dilatation. Drugs used for pupil dilatation have many side effect from necrotizing enterocolitis to myoclonic seizures. Therefore there is a need for wide angle fundus imaging without pupil dilatation in premature babies. Purpose: To describe new wide angle fundus imaging method by using transpalpebral...

Photoreceptors Exhibit Optical Fiber Property Due to Physical Properties, Including Their Shapes, Diameters and Indices of Refraction

Photoreceptors exhibit optical fiber property due to physical properties, including their shapes, diameters and indices of refraction. Because of their wave-guiding properties, visual perception of light is weakened by the obliquity of the incident rays. Light rays passing through the centre of the pupil appear brighter than peripheral rays. This phenomenon is called the Stiles-Crawford effect. In an emmetropic eye, every wave front related...
