Background: The prevalence of myopia keeps increasing during the COVID-19 pandemic. We aimed to map the worldwide treatment preferences of ophthalmologists managing myopia control during the first wave of the pandemic. Methods: An online questionnaire inquiring about pharmacological and optical treatment patterns during the first half of 2020 was sent to pediatric ophthalmology as well as general ophthalmology memberships worldwide. The results among pediatric ophthalmologists were compared to a previous study we performed before the pandemic. Results: A total of 2269 respondents from 94 countries were included. Most respondents were pediatric ophthalmologists (64.6%), followed by ophthalmologists from other subspecialties (32.3%). The preferred modality for all geographical regions was a combination therapy of pharmacological and optical treatments. When evaluated independently, the pharmacological treatment was more popular than the optical treatment in most regions other than East Asia (P < 0.001). Compared to a pre-pandemic questionnaire, the participation of pediatric ophthalmologists affiliated with non-university hospitals increased. Additionally, the prevalence of respondents utilizing either any type of pharmacological treatment and those that using only evidence-based treatments increased globally. Although a decline in the use of optical treatment was evident worldwide, the use of evidence-based optical treatments increased. Conclusion: Ophthalmologists around the world preferred a combination therapy of pharmacological and optical treatments. More pediatric ophthalmologists treated myopia progression and preferred a better evidence-based approach to control myopia. These trends reflect a positive response and more awareness of the rising prevalence of myopia due to the increased burden of myopia imposed by the COVID-19 pandemic. [ABSTRACT FROM AUTHOR]

Purpose: To assess the associations between the prevalence of congenital color vision deficiency (CVD) and genetics and environment, represented by place of origin (ethnic background) and place of birth, respectively. Methods: This is a retrospective study of the computerized database of the northern recruitment center of Israel of 53,895 consecutive male Jewish conscripts 16–19 years old, who completed the medical profiling process between 1988 and 2011. CVD was diagnosed using the 24-pseudo-isochromatic plate Ishihara test. Associations of CVD prevalence with sociodemographic variables, anthropometric indices, refractive errors, and mainly place of origin and place of birth were tested by both univariate analysis and multivariate regression models. Results: Elevated BMI (obesity) and blood pressure (hypertension), as well as myopia, were all positively associated with congenital CVD. The composition of the study population provides a unique opportunity to investigate the relationship between ethnicity and environment. The prevalence of CVD significantly differs among subpopulations of different ethnic background as well as among those who were born in different geographical locations. Additionally, differences in the prevalence of CVD (1.2–1.6%) were observed among conscripts from the same origin, who were born in Israel, compared to those who were born elsewhere. Both place of origin (p < 0.01) and place of birth (p < 0.05) were associated with the prevalence of CVD in a multivariable regression model. Conclusion: This study affirms previously established associations of CVD with certain variables and reveals a possible novel association of CVD with environmental factors. [ABSTRACT FROM AUTHOR]

Purpose: To explore what the current worldwide preferred practice patterns of pediatric ophthalmologists are to decrease myopia progression among their patients.Methods: A questionnaire was sent to all members of supranational and national pediatric ophthalmology and strabismus societies.Results: The questionnaire was fully completed by most respondents 90.10% (847 of 940 responses). Fifty-seven percent (457) routinely treat to decrease myopia progression. The most common parameter to initiate treatment was a myopic increase of 1 diopter/year or more (74.8%, 246). Seventy percent (345) prescribed eye drops. Atropine 0.01% was the most popular (63.4%, 277) followed by atropine 1% (10.9%, 48) and atropine 0.5% (8.9%, 39). Eighty-six percent (394) of the respondents advised to spend more time outdoors, to reduce the amount of time viewing screens (60.2%, 277), and cutback the use of smart phones (63.9%, 294).Conclusions: Most pediatric ophthalmologists treat to decrease myopia. They employ a wide variety of means to decrease myopia progression. Atropine 0.01% is the most popular and safe modality used similarly to recent reports. However, there is no consensus when treatment should be initiated. Further prospective studies are needed to elucidate the best timing to start treatment and the applicability of recent studies in the Asian population to other ethnic groups. This will improve the ability to update pediatric ophthalmologist with evidenced-based treatment options to counter the myopia epidemic. [ABSTRACT FROM AUTHOR]

Introduction: Characteristics of ophthalmia neonatorum (ON) amongst paediatric ophthalmologists remain unclear. The purpose of this current study is to examine the incidence, diagnosis, treatment, and prophylaxis of ON cases presenting to members of the American Association of Paediatric Ophthalmology and Strabismus (AAPOS). Methods: An email containing a web link to a survey was sent to all members of AAPOS. The questionnaire examined the incidence of ON, etiology, diagnostic methods, treatment, and prophylaxis of the disease in different countries around the world. Results: Two hundred and ninety-one ophthalmologists answered the questionnaire. Most were from North America (52.94 %). One hundred and seventy-six (60.69 %) ophthalmologists encountered 0-5 cases of ON per year. The most common pathogens causing ON was Chlamydia trachomatis (35.37 %). Two hundred and forty-two (85.21 %) treat empirically when encountering ON during the first 10 days of life and 205 (75.09 %) after the first 10 days of life. In both cases, erythromycin was the most common first line of treatment. Two hundred and twenty-two (78.72 %) ophthalmologists replied that prophylactic treatment is required in their country. The most common agent for prophylaxis was erythromycin ointment (71.50 %). Conclusions: We found that the incidence of ON per year per practitioner is 0-5 cases, the most common etiology is C. trachomatis, and most infants receive prophylaxis and treatment.

Purpose: The precise correction of refractive error is especially important in young adults. It is unclear whether cycloplegic refraction is necessary in this age group. The purpose of this study was to compare the non-cycloplegic and cycloplegic spherical equivalent (SE) refractive error measured in young adults. Methods: This was a prospective study of 1400 eyes ( n = 700) of enlisted soldiers aged 18 to 21 years who were consecutively evaluated in an outpatient army ophthalmology clinic. One drop of cyclopentolate 1 % was installed twice 10 min apart, and cycloplegic refraction was performed in both eyes 40 min later using an auto-refractor. The difference between non-cycloplegic and cycloplegic refractive measurements was analyzed. Results: The mean difference in SE between non-cycloplegic and cycloplegic measurements was 0.68 ± 0.83 D (95 % CI, 0.64-0.72). Significantly greater differences were observed in hypermetropes than myopes (1.30 ± 0.90 D versus 0.46 ± 0.68 D, p < 0.001). Moderate hypermetropes (2 to 5 D) demonstrated significantly greater refractive error than mild (0.5 to 2 D) or severe (>5 D) hypermetropes (1.71 ± 1.18 D versus 1.19 ± 0.74 D and 1.16 ± 1.08 D respectively, p < 0.001). Conclusions: Young hypermetropic adults possessed +1 to +2 D of latent hypermetropia. In contrast, young myopic adults revealed pseudomyopia of −0.5 D. Cycloplegic refraction should be performed in young hypermetropic adults complaining of various signs of asthenopia. [ABSTRACT FROM AUTHOR]

Purpose: The purpose of this study was to investigate the long-term outcome of high hypermetropic refractive errors in childhood. Methods: We retrospectively reviewed data from the clinical records of 164 children with spherical equivalent (SE) hypermetropic refractive errors in three medical centers collected over 29 years. Refractive errors between +1.00 and +3.00 diopter (D) on initial examination were classified as mild hypermetropia and those +5.00D or greater were classified as high hypermetropia. The four variables studied were, age, refractive error, strabismus, and gender. The rate of reduction in hypermetropic refractive error was calculated over time in years. We identified subgroups according to age, gender, and initial refractive error. Results: Seventy-eight children with high hypermetropia and 86 children with mild hypermetropia were studied. High hypermetropia was detected at a mean age of 3.3 years, while mild hypermetropia was detected at a mean 4 years of age. The mean follow-up was 6.6 years for high hypermetropia and 6.4 years for mild hypermetropia. Over the follow-up period, children in all subgroups tended to reduce their refractive errors. The reduction in refraction power was small for both mild and high hypermetropic refractive errors. Amblyopia in the high hypermetropia group was more common and more refractory to treatment. Conclusions: Most children with hypermetropia of less than +3.00D experience a reduction in hyperopic refractive error over time and will outgrow any need for corrective lenses. Children with hyperopia greater than +5.00D will not experience a significant reduction in the power of the refractive error. [ABSTRACT FROM AUTHOR]
