Variations of Cup-to-Disc Ratio in Children

Abstract

Purpose: The aim of this study is early detection of increased cup to disc ratio and a survey study of cup-disc ratio in Egyptian children age group less than 15 years. Methods: Three hundred and eighty-two (382) children were enrolled in this study. They were classified into three age groups; infants' Group (1) from 0 -2 years, preschool Group (2) from 2 -6 years and school children Group (3) from 6 -15 years old. C/D ratio was measured for each child.

Profile of primary childhood glaucoma at a child eye health tertiary facility in Malawi

“…The normal CDR is less than 0.1 in the first year of life and it can increase up to 0.3 by 15 years of age [ 24 ]. The high mean CDR of 0.73 from our study population signifies advanced disease presentation and the need for urgent surgical intervention to improve visual prognosis.…”

Surgical interventions for primary congenital glaucoma

“…In a child, the scleral canal is distensible, and cupping in PCG proceeds more rapidly and is occasionally reversible (Quigley 1977; Quigley 1982; Robin 1979). A cup/disc ratio greater than 0.3 also may be indicative of glaucoma (normal 0 mm to 0.1 from birth to two years and 0.1 mm to 0.2 from two to six years) (Amer 2014). …”

Incidence of Ophthalmic Disease in the Dakhla Oasis in Egypt by a prevention of blindness major campaign

“…The pterygium, lacrimal intubation, lid surgeries and the limbal mass were done by the surgical team in the central hospital we found that the trachomatous complications 81%were the majority of the problems solved by minor surgeries . In revision of the various reports of the WHO about blindness worldwide 17 and other studies in Egypt [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21] , it is clear that The Egyptian Oasis is not far from the estimated rate of blindness as well as the prevalence of eye disease as shown in our results.…”

“…The screening study was also a way of training residents and interns about working with such large number of population. [19][20][21] Working as an assistant in the medical and surgical divisions of the campaign provided a great experience of learning for younger generation. They examined most of the varieties of ophthalmic diseases having the chance to acquire knowledge from the attending professor or consultant.…”
