“…In this cross sectional study, the prevalence of KC was 1.7% .This prevalence is consistent with the results reported in other middle-eastern countries (Shehadeh et al, 2015;Brlin et al, 2012;Millodot et al, 2011;Waked et al, 2012) where a much higher prevalence of KC is demonstrated in comparison to other regions of the world (Nielsen et al, 2007;Owens et al, 2003;Tanabe et al, 1985).…”

“…The prevalence in our study was comparable to the study among Palestinian tertiary students (1.5%) (Shehadeh et al, 2015) where they used simplified nomenclature for describing keratoconus among Published by SCHOLINK INC. similar age group participants (Brlin et al, 2012) but lower among Arab students in Israel where the prevalence was 3.1% as they used a simplified criteria of four topographic indices to diagnose manifest KC (Millodot et al, 2011).…”

Purpose: To screen for keratoconus (KC) and potential associated risk factors in a sample of medical students. Methods: This cross sectional study included 120 medical students studying at The University of Jordan. They were randomly selected from a total of 400 students. Participants responded by completing a self-administered questionnaire. Following initial clinical evaluation, corneal tomography images and indices were analyzed by an experienced ophthalmologist, after which the participants were classified into: normal, KC suspects and KC patients. Results: A total of 120 participants (mean age, 23.1 ±0.5 years) were included in this study, 70 (58.3%) were females and 50 (41.7%) were males. Two subjects had KC, demonstrating a prevalence of 1.7% while five (4.2%) participants showed at least two abnormal indices and were considered as KC suspects.Conclusion: the result of this study is similar to other studies conducted in the Middle East, which indicates a higher prevalence of KC than other western countries. Combined with the significantly impaired vision-related quality of life and the relatively young onset of disease, the burden of keratoconus represents a significant public health concern.

“…4 Prevalence of KC is higher in the Middle East than in other areas, as proved by literature. 9,10,[14][15][16][17] This might be due to the high incidence of chronic allergies and spring catarrh. 17 In our study, VKH was reported in 35% of cases with subclinical KC, which is comparable to the value obtained by Omar & I.A.N who reported a 37.5% prevalence of VKC in KC eyes in Egyptian children with myopia.…”

“…Also, we divided cases into two age groups in order to highlight the higher prevalence rate of the disease among older age groups, as we report a higher percentage (8.2%) of subclinical KC among the older age group (12)(13)(14)(15)(16)(17)(18) years as compared to (1.4%) in the younger age group. A result was consistent with Awwad et al study that reported an increased prevalence of KC among increasing age groups of pediatric first-degree relatives of KC patients.…”

Purpose: To report the prevalence of subclinical keratoconus (KC), and KC suspects, in pediatric Egyptian population with astigmatic error ≥2 diopters (D), with the use of CSO Sirius tomographer. Methods: A cross-sectional study that included all the children aged 6-18 years with an astigmatic error of ≥2 D who attended the pediatric ophthalmology clinic for routine checkups during the period between March 2017 and December 2017 was done. All subjects underwent comprehensive ophthalmic examination, and corneal imaging using CSO Sirius instrument, a pentacam with Scheimpflug technology. Results: There were 547 subjects enrolled in our study. Mean age was 11.34 ± 3.03 (range 6-18) years. There were 278 subjects (50.8%) between 6 and 12 years, and 269 subjects (49.2%) between 12 and 18 years. Males represented 48.4% and females represented 51.6% of patients. Among all the subjects, there were 26 (4.8%) KC patients, 24 (4.4%) KC suspects, and 497 (90.9%) were normal. Conclusion: Prevalence of subclinical KC among pediatric age group with astigmatism is relatively high, hence the importance of corneal tomography screening of children with astigmatic error ≥2 D.

“…Based on the literature as well as medical and ophthalmological expertise, it is noticed that KC is a major and common eye disease among the Palestinian population compared with other countries. This might be due to genetic and environmental risk factors, such as sun exposure (ultraviolet exposure) and nicotine [ 9 ]. Another factor associated with an increase in the risk of KC is consanguinity [ 10 ], which is prevalent in our country.…”

Characteristics of keratoconic patients at two main eye centres in Palestine: a cross-sectional study

et al. 2018

BackgroundKeratoconus (KC) is a multifactorial, degenerative ectatic condition of the cornea. It usually manifests during late adolescence or the early twenties. A painless disease, KC may end with severe visual loss. The prevalence of KC in middle-eastern countries is much higher than in other regions of the world. This may be due to genetic and environmental risk factors and consanguinity. The goal of this study is to explore the demographic profile of Palestinian keratoconic patients.MethodsA retrospective study was conducted in two ophthalmology centres (Tertiary Ophthalmic Centre of An-Najah National University Hospital and An-Noor Centre at the Specialized Arab Hospital). All medical charts of keratoconic patients attending both centres over the period from 2009 to 2016 were reviewed. These patients were diagnosed by ophthalmologists depending on history, examination and Pentacam. Severity was determined using the k median index from the Pentacam map. Data analysis was carried out using SPSS Version 22.ResultsThe medical files of 936 keratoconic eyes of 505 keratoconic patients were reviewed. Their mean age at the time of diagnosis was 23.3 ranging from 8 to 62 years. Approximately 70.1% of them presented after the age of 20 years, and younger age groups were more likely to develop a severe disease stage than older ones (P = 0.001, r = − 0.108). There was a nearly equal distribution of patients between the two sexes (49.5% male, 50.5% female). On initial evaluation, the best-corrected visual acuity (BCVA) was recorded as ≥6/12 in most affected eyes (71.5%). Regarding severity, 62% presented in a mild form, while 9.9% were at a severe stage. About 88.2% presented with bilateralism.ConclusionsMost of the patients in their twenties presented with a mild bilateral form of the disease. This result is compatible with published international reports. It is recommended that the results of this study be considered when establishing a screening program in Palestine. Subsequently, patients will be identified at an appropriate time where action can be taken before disease progression take place.
