“…Keratoconus is 10.3389/fped.2022.937246 typically manifested at puberty and progresses until the third or fourth decade of life (1,5). The distribution of keratoconus severity varies in different age groups, (6)(7)(8) and males account for a higher proportion of keratoconus cases than females according to previous studies (8,9). However, subgroup analysis combining gender and age is more helpful to elucidate the characteristics of keratoconus in detail, which is limited in application.…”

PurposeTo evaluate the distribution of pediatric keratoconus patients and the disease severity based on different age and gender groups in China.Materials and methodsA total of 446 keratoconus eyes in 266 pediatric patients from January 2019 to January 2022 were included in the cross-sectional study. The clinical findings and severity of keratoconus were recorded and Kruskal–Wallis test, chi-squared test, and Cochran-Mantel-Haenszel (CMH) test were used to compare the parameters between different gender and age groups.ResultsThe male/female ratio was 353/93 (3.8:1), and the median age was 16 years (range: 6–17 years). Male patients were statistically younger than female patients (P = 0.041). The male/female ratio decreased with age (P for trend = 0.011). The distribution of the topographic keratoconus classification (TKC) stage was significantly different between gender and age groups (all P < 0.05). Male patients had a higher ratio of advanced keratoconus eyes (TKC ≥ 3) than female patients (P < 0.001), and CMH analysis indicated that being a male was a risk factor for advanced keratoconus after controlling for age (odds ratio: 2.581, P < 0.001).ConclusionMale keratoconus patients were younger, with a higher ratio of advanced keratoconus than female patients in the Chinese pediatric patients evaluated. Multicenter studies with larger sample sizes are necessary in the future.

“…Elbedewy et al [23] found that 54.2% of the affected eyes had a mild degree of KC, 27.1% had a moderate degree, while 18.7% suffered from the severe form. also a study in Jordan [20] found that most of the eyes were mild 63.3%, followed by moderate 24.7%, and then severe 11.9%. however a study in Iran [26] found that The frequency of moderate (56.4%) and severe (28.4%) KC was more than mild cases (15.2%) and said this because patients with more severe disease seek medical advice more.…”

Objectives: The aim of this study was to evaluate the demographic profile, refractive ,topographic and tomograghic characters of keratoconus patients in Egypt. Patients and Methods: This study was designed as a retrospective cohort clinical study. The study met the ethical criteria of the Institutional Review Board (IRB) in Faculty of Medicine Benha University with approval No. of (MS 32-12-2019). Our study included 102 eyes of 51 patient in the keratoconus group and 100 eyes of 50 patients in the control group. The study was designed as a retrospective cohort clinical study on keratoconus patients who attended at Al Ferdaws eye hospital in the period from January 2016 to December 2020. Study groups: Group 1: normal eyes as a control group. Group 2: keratoconus group (KC). Data Synthesis: The results analyzed using SPSS25, T-test, Mann-Whitney U test and Chi-square test. Findings: There was clinically significant difference between normal and KC cases regarding the cylinder, BCVA, keratometric power of anterior and posterior surface on both flat and steep meridian.also K max and km.,Q value at 6 mm., thinnest location, relative thickness map average,thickness profile map average (PPI),highest elevation front and back,corneal irregularity indices, corneal aberrometric values, BAD_ D and ARTmax. Conclusion: We found no significant associationbetween the severity of KC with age and sex. many parameters in topography and tomography were efficient in differentiating normal cases from keratoconus cases even in early disease.
