Diclofenac versus fluorometholone after strabismus surgery in children

Abstract

Postoperative topical diclofenac is an excellent substitute for steroids, particularly in young children under 7 years of age.

Quantification of Astigmatism Induced by Pterygium Using Automated Image Analysis

“…23 In addition, CLAHE was proven to be the most reliable algorithm for objective measurement of conjunctival redness in a previous study 23 and was also successfully used for the quantification of postoperative conjunctival injection. 24 Studies have been performed to analyze the correlation between the size of pterygium and induced corneal astigmatism. Most studies reported a significant correlation between the horizontal extension onto the cornea and the amount of induced astigmatism.…”

“…23,24 Briefly, the color image was converted to a grayscale image and contrast was enhanced using CLAHE. CLAHE partitions the image into small contextual regions (size of tiles: 8 · 8 with a clip limit of 0.01) and applies the histogram equalization to each region.…”

“…algorithm was calculated as the ratio of the number of pixels that are identified as vessels to the total number of pixels in each region, and these values range from 0 to 100. 23,24 The region of pterygium covering the cornea was marked as the region of interest from an anterior segment photograph, and the VI measured using the CLAHE algorithm was automatically expressed (Fig. 2).…”

Risk Factors for Recurrence After Pterygium Surgery

“…[23][24][25] Briefly, the color image was converted to a gray-scale image and contrast was enhanced using CLAHE. CLAHE partitions the image into small contextual regions (size of tiles: 8 · 8 with a clip limit of 0.01) and applies the histogram equalization to each region.…”

“…The enhanced image was thresholded and divided into red vessels and background, and then, the feature based on this algorithm was calculated as the ratio of the number of pixels that are identified as vessels to the total number of pixels in each region, and these values range from 0 to 100. 23,25 The region of pterygium was manually marked as the region of interest from an anterior segment photograph, and VI was automatically expressed (Fig. 2).…”
