“…Similar findings were extensively reported in many other studies. 1 , 6 , 7 , 10 , 20 – 25 In the literature, the predominance of males referred to low vision clinics has been explained by the higher risk of visual impairment in males and higher mortality rate in females, 6 gender-based discrimination in access to eye care clinic, 7 literacy, and social constraints. 24 In our study, socio-cultural beliefs were substantial too, and Middle Eastern families tend to prioritize eye care for males over females because the former are required to bear more financial commitment and this may explain the higher number of males seeking low vision services.…”

AimThe aim of the study was to identify causes of visual impairment among patients attending a low vision clinic in the north of Jordan and to study the relevant demographic characteristics of these patients.Subjects and methodsThe retrospective study was conducted through a review of clinical records of 135 patients who attended a low vision clinic in Irbid. Clinical characteristics of the patients were collected, including age, gender, primary cause of low vision, best corrected visual acuity, and current prescribed low vision aids. Descriptive statistics analysis using numbers and percentages were calculated to summarize categorical and nominal data.ResultsA total of 135 patients (61 [45.2%] females and 74 [54.8%] males) were recruited in the study. Mean age ± standard deviation for the study population was 24.53 ± 16.245 years; age range was 5–90 years. Of the study population, 26 patients (19.3%) had mild visual impairment, 61 patients (45.2%) had moderate visual impairment, 27 patients (20.0%) had severe visual impairment, and 21 patients (15.6%) were blind. The leading causes of visual impairment across all age groups were albinism (31.9%) and retinitis pigmentosa (RP) (18.5%). Albinism also accounted for the leading cause of visual impairment among the pediatric age group (0–15 years) while albinism, RP, and keratoconus were the primary causes of visual impairment for older patients. A total of 59 patients (43.7%) were given low vision aids either for near or distance. The only prescribed low vision aids for distances were telescopes. For near, spectacle-type low vision aid was the most commonly prescribed low vision aids.ConclusionLow vision services in Jordan are still very limited. A national strategy programme to increase awareness of low vision services should be implemented, and health care policies should be enforced to cover low vision aids through the national medical insurance.

“…Proportion of retinal blindness varies in between different countries and ranges from just over 2% in poor countries [ 19 , 20 ] to almost 50% in high income countries [ 4 ]. While retinitis pigmentosa and retinal dystrophies are common retinal causes of vision loss in children [ 21 ], ROP is an emerging condition especially in children in middle-income countries like Turkey [ 7 ] and Surinam [ 11 ]. With improving neonatal care for preterm babies in Eritrea [ 22 ], a rise in the number of children with ROP can be expected.…”

BackgroundProper information on causes of childhood vision loss is essential in developing appropriate strategies and programs to address such causes. This study aimed at identifying the causes of vision loss in children attending the national referral eye hospital with the only pediatric ophthalmology service in Eritrea.MethodsA retrospective data review was conducted for all the children (< 16 years of age) who attended Berhan Aiyni National Referral Eye Hospital in five years period from January 2011 to December 2015. Causes of vision loss for children with vision impairment (recorded visual acuity less than 6/18 for distance in the better eye) was classified by the anatomical site affected and by underlying etiology based on the timing of the insult and causal factor.ResultsThe medical record cards of 22,509 children were reviewed, of whom 249 (1.1%) were visually impaired. The mean age of the participants was 7.82 ± 5.43 years (range: one month to 16 years) and male to female ratio was 1:0.65. The leading causes of vision loss were cataract (19.7%), corneal scars (15.7%), refractive error and amblyopia (12.1%), optic atrophy (6.4%), phthisis bulbi (6.4%), aphakia (5.6%) and glaucoma (5.2%). Childhood factors including trauma were the leading causes identified (34.5%) whereas other causes included hereditary factors (4%), intrauterine factors (2.0%) and perinatal factors (4.4%). In 55.0% of the children, the underlying etiology could not be attributed. Over two-thirds (69.9%) of vision loss was potentially avoidable in nature.ConclusionThis study explored the causes of vision loss in Eritrean children using hospital based data. Cataract corneal opacities, refractive error and amblyopia, globe damage due to trauma, infection and nutritional deficiency, retinal disorders, and other congenital abnormalities were the leading causes of childhood vision impairment in children attending the tertiary eye hospital in Eritrea. As majority of the causes of vision loss was due to avoidable causes, we recommended primary level public health strategies to prevent ocular injuries, vitamin A deficiency, perinatal infections and retinopathy of prematurity as well as specialist pediatric eye care facilities for cataract, refractive errors, glaucoma and rehabilitative services to address childhood vision loss in Eritrea.

“…Among LV chi ldren in Nepal, refractive error and amblyopia (20.1%), retinitis pigmentosa (14.9%), and macular dystrophy (13.4%) were the most common causes of pediatric VI. Nystagmus (50%) was the most common cause of LV in the one to five years age group, whereas refractive error and amblyopia were the major causes in the six to 10 and 11 to 16 years age group (17.6 and 22.9%, respectively) [12].…”

Introduction/Objective The objectives of the paper are to assess the causes of low vision (LV) in pediatric population in Montenegro and to evaluate the influence of low vision aids (LVA) on reading performance regarding the speed of reading and the understanding of the read text. Methods A prospective study was conducted on 40 "treatable" LV children what represent all registered LV children in Montenegro. All participants read the same text before and after using LVA. Reading rate was calculated as the number of words read per minute. Functional speed of reading was calculated as the ratio of the rate of reading and the understanding of the read text multiplied by 100. Results The study comprised 40 LV children with the mean age of 12.60 ± 4.06 years (20 boys and 20 girls). The most common cause of LV in children were premature retinopathy (10/40 or 25%), retinitis pigmentosa (8/40 or 20%), optic nerve anomaly (5/40 or 13%), degenerative myopia (4/40 or 10%), macular dysgenesis (4/40 or 10%), Stargardt disease (3/40 or 7%), optic nerve atrophy (2/40 or 5%), and albinism (2/40 or 5%). Nystagmus was found in 11 LV children or 28% of the group. LVA were prescribed to all of them. Reading speed before vs. after LVA use was 36.58 ± 35.60 vs. 73.83 ± 27.05 words/minute (p < 0.001), while functional reading was 26.00 ± 30.43 vs. 59.41 ± 29.34 (p < 0.001). Conclusion LV children demonstrate a significant improvement in reading performance by using LVA.
