Abstract

Background: Diabetic retinopathy is a leading cause of vision impairment and a significant complication of diabetes mellitus, especially in low- and middle-income countries. This study aimed to identify the barriers affecting diabetic retinopathy screening among people with diabetes mellitus. Methods: This cross-sectional study was conducted between April and October 2024 at the National Center for Diabetes, Endocrinology and Genetics. Data collection was performed using a structured, validated electronic questionnaire adapted from previous studies. Sample size calculation was carried out before data collection. Data were collected using a structured electronic questionnaire. A total of 998 responses were included in the study. The collected data incorporated sociodemographic characteristics, diabetes history, screening practices, and reported barriers. Descriptive and categorical data analyses were performed. Results: Of 998 participants, 82% were over 50 years old, 79% had type 2 diabetes mellitus, and 30% had never had an eye examination. Diabetic retinopathy was diagnosed in 12%. The main barriers to regular attendance among those previously screened (699) were as follows: lack of awareness of its importance (11%), believing that being asymptomatic made screening unnecessary (19%), and transportation difficulties (14%). Among those never screened (299), 56% lacked awareness, 62% believed being asymptomatic negates the need for screening, and 13% faced transportation difficulties. Age > 50 years, higher educational level, availability of health insurance, longer duration of diagnosis of diabetes mellitus, and HbA1c > 7% were significantly associated with prior screening (p < 0.05). Conclusions: Public health strategies should enhance the education provided to people and physician–person communication and remove logistical obstacles to improve screening compliance.

1. Introduction

Diabetes mellitus is a global public health problem increasing in prevalence and impact, especially in middle- and low-income countries [1]. The number of individuals with diabetes is estimated to grow annually by 2.2%, which is nearly double the annual growth rate of the global population [2]. The Middle East and North Africa (MENA) region has the highest regional incidence at 84.7 million (17.6%), and this is expected to rise significantly to 163 million by 2050 [3]. In Jordan, the overall age-standardised rates of individuals diagnosed with diabetes rose from 13% in 1994 to 23.7% in 2017 [4].
Diabetic retinopathy, a disease that affects the microvasculature of the retina, is a major complication of diabetes [5]. There are two types of diabetic retinopathy: non-proliferative diabetic retinopathy (NPDR) and proliferative diabetic retinopathy (PDR). Another complication of diabetes is diabetic macular oedema, which is defined by the Early Treatment Diabetic Retinopathy Study (ETDRS) as a retinal thickening or the presence of hard exudates within 1 disc diameter of the macula [6]. PDR and diabetic macular oedema are the main complications that result in vision-threatening diabetic retinopathy (VTDR). Similarly, diabetic retinopathy and VTDR are among the leading causes of blindness worldwide, with recent studies predicting that the number of adults with diabetic retinopathy and VTDR will rise from 103.12 million and 28.54 million in 2020 to 160.50 million and 44.82 million by 2045, respectively [7]. A combination of screening, good blood glucose management, early detection, and treatment of any retinal changes reduces the risk of VTDR [8,9].
These conditions, occurring individually or in combination, are asymptomatic in the early stages. Therefore, they are best recognised early on through retinal examination [10]. A unified screening programme would not only detect changes early, but could reduce the percentage of diabetic retinopathy positive results [11]. The recommendations for the initial examination are as follows: 5 years after diagnosis for type 1 diabetes and at the time of diagnosis for type 2 diabetes [12]. For follow-up, if there is no diabetic retinopathy, every 1 to 2 years; if mild NPDR, every 6 to 12 months; if moderate NPDR, every 3 to 6 months; if severe NPDR, once every less than 3 months; if PDR, at least once every month [8].
Several studies have examined the barriers to diabetic retinopathy screening among people with diabetes. Some of these barriers are as follows: sociodemographic disparities, such as race and gender, difficulties obtaining time off work/study to attend appointments, anxiety about screening results, younger age groups, lower levels of income and education, difficulty accessing screening services and scheduling appointments, lack of awareness of the reasons for screening, time required for registration, and a lack of readily available information in their local area/practice [13,14,15,16].
The study aims to identify the barriers that affect adherence to regular diabetic retinopathy screening among people with diabetes. Although these barriers have been studied individually in other countries, this research integrates multiple previously reported barriers within a single framework in the Jordanian population, addressing an important gap in the national literature. Based on the findings, policy-relevant strategies include enhancing patient education at the time of diabetes diagnosis, improving physician–patient communication about the importance of eye health, and mitigating practical barriers such as transportation challenges and limited appointment accessibility, which together may strengthen adherence to the recommended screening schedules.

2. Materials and Methods

This cross-sectional study, conducted at the National Center for Diabetes, Endocrinology and Genetics (NCDEG), examined the barriers to ophthalmic screening among the Jordanian population. Institutional Review Board (IRB) approval was obtained in April 2024. The IRB approval number was 1/2024.
The planned sample size was based on estimating the prevalence of never having had an ophthalmic examination among people with diabetes. Using the single-proportion formula (n = Z2·p·(1 − p)/d2) with Z = 1.96 for 95% confidence, an anticipated prevalence p = 0.30 (based on pilot data and prior regional studies) [17], and a precision (d) of 0.03 (3 percentage points), the required sample size is approximately 897. To allow for incomplete responses and subgroup analyses, the sample size was inflated by 10%, giving a target of around 987 participants. A total of 1016 participants with diabetes from NCDEG’s outpatient clinics were enrolled, and 18 incomplete responses were excluded, resulting in an analytic sample of 998. The total number of patients approached and the response rate were not formally recorded. NCDEG is a specialised diabetes centre and has individuals from all regions of Jordan, with a wide range of socioeconomic and demographic backgrounds, supporting the diversity of the study population. Data collection was performed using a questionnaire between April and October 2024 in the institution’s waiting hall, and they were invited to inquire if any question was unclear. The researchers read the questions for individuals who could not read. The inclusion criteria were individuals of any age and gender with type 1 or type 2 diabetes. To minimise selection bias, they were recruited in a consecutive manner during the study period.
Participants who declined to provide informed consent or individuals unable to complete the questionnaire due to severe cognitive impairment or acute illness at the time of recruitment were excluded from the study.
A structured questionnaire was designed based on similar studies [17,18,19]. The data collection tool was developed based on an extensive literature review and existing validated questionnaires. It was reviewed for content and face validity by a panel of five experts in endocrinology, ophthalmology, public health, and survey methodology. A pilot study (n = 50) was conducted to assess the clarity, feasibility, and comprehension of the questionnaire items; pilot responses were not included in the final analysis. Formal reliability testing (e.g., Cronbach’s alpha) was not performed. The questionnaire was developed in Arabic, the native language of participants, and was reviewed by two language experts to ensure clarity, cultural appropriateness, and accurate phrasing.
Standardised information about the identity of the researchers, the purpose of the study, how the data provided will be used, the estimated time to complete the questionnaire, voluntary participation, privacy, confidentiality, and anonymity of the data was explained to the participants before data collection, and they all consented before enrollment. The questionnaire was divided into four sections. The first section covered sociodemographic data, such as age, gender, living area, educational status, smoking and alcohol use, insurance, and whether they were employed in the healthcare sector or had a first-degree relative working in the medical sector. The second section covered their diabetes profile: the type of diabetes, duration since diagnosis, frequency of HbA1c testing, their most recent and their highest HbA1c level, and whether they had ever attended the ophthalmology clinic since their diagnosis. Based on their answer, the questionnaire would then move on to two different sections. Both sections included potential barriers to regular eye examination. However, those who had previously undergone an ophthalmic examination would also be asked about examination frequency, prior diagnosis of diabetic retinopathy, and if so, what treatment they have received. Additionally, participants were given the opportunity to provide their own perceived barriers which had not been captured by the questionnaire. All variables, including clinical information such as HbA1c levels, history of diabetic retinopathy, and prior ophthalmic treatments, were self-reported by the respondents, and no data were extracted from medical records. Responses of “I don’t know” were treated as a valid response category. HbA1c levels were reported as derived NGSP units (%—one decimal) in accordance with the unit used in NCDEG, which was then converted to IFCC units (mmol/mol). The primary outcome variable was history of having undergone an eye examination for diabetic retinopathy (ever vs. never), while the analysis primarily focused on identifying sociodemographic and participant-reported barriers associated with non-attendance or delayed eye examination (see Supplementary Material for the questionnaire).
The Statistical Package for the Social Sciences (SPSS) version 21.0 (IBM Corp., Armonk, NY, USA) was used for statistical analysis. Frequencies and percentages were used to convey qualitative data, whereas means and standard deviations (SDs) were used to summarise quantitative variables. The χ2 test assessed associations between categorical variables, and p values < 0.05 were considered statistically significant.
Associations of age, gender, education, income, insurance status, type and duration of diabetes, HbA1c levels, and family or personal healthcare employment were compared between those who attended and those who did not attend eye clinic appointments. HbA1c levels were categorised as within or above recommended targets in accordance with the recommendation of the American Diabetes Association (ADA) [20]. Variables showing clinical relevance or statistical significance in bivariate analyses were entered into a multivariable logistic regression model to identify factors independently associated with having undergone an eye examination. Results are reported as adjusted odds ratios (aORs) with 95% confidence intervals (CIs). To address small cell sizes, categories with low frequencies were combined where appropriate, and variables with sparse distributions were excluded from the multivariable model. No additional subgroup or sensitivity analyses were performed.

3. Results

3.1. Sociodemographic Characteristics of Participants

The study had 998 participants. As shown in Table 1, the majority were over 50 years old (82%). Most participants resided in urban areas and had a school-level education or higher. A significant proportion were non-smokers, and nearly all participants reported no alcohol consumption (99%). The majority had health insurance (97%) and 70% reported an income of less than JOD 1000.

3.2. Diabetes Profile

Table 2 demonstrates that the majority of participants had type 2 diabetes (79%). A significant portion (79%) had been living with diabetes for over 5 years. Most participants reported testing their HbA1c levels every 1–3 months. The last recorded HbA1c levels were mainly between 6 and 8%, with 14% reporting levels above 9%. A total of 70% had at least one ophthalmic examination since their diagnosis, and 27% of those had a screening interval of more than a year.

3.3. Diagnosis and Treatment of Diabetic Retinopathy

Table 3 shows that among the participants who had previously attended the ophthalmology clinic, 18% were diagnosed with diabetic retinopathy. Of these, 82% received laser-based treatment, retinal injections, or both.

3.4. Barriers to Having an Eye Examination Among Those Never Screened

The primary barrier to diabetic retinopathy screening among individuals never screened was lack of knowledge and perception, as shown in Table 4, with 56% reporting that their doctor did not mention it, and 62% believing that being asymptomatic negates the need for attendance. Almost one third of the patients reported logistical barriers such as transportation difficulties, and 59% reported multiple barriers.

3.5. Factors Contributing to the Delay in Regular Eye Examinations

For participants with prior eye examination, Table 5 displays that the majority (54%) believed that they were committed to attending appointments at the time they were surveyed. However, they were asked to mention if there are any factors that could hinder their commitment regardless. The most common factors contributing to the delay were knowledge and perception barriers, such as lack of awareness about the importance of regular reviews, and thinking that being asymptomatic eliminates the need for regular examinations. This was also followed by logistical barriers. Notably, 28% of participants cited more than one reason for the delay.

3.6. Problems Encountered During Eye Examinations

Table 6 illustrates that the majority of participants who had previously undergone an eye examination reported no issues. However, the most common reported problems were long waiting times, discomfort or inability to drive after dilation drops, and discomfort with the examination itself. A subset of participants (13%) encountered multiple problems.

3.7. Effect of Sociodemographic Characteristics and Diabetic Profile on Diabetic Retinopathy Screening (n = 998)

When examining the sociodemographic characteristics associated with having undergone at least one eye examination since diagnosis, Table 7 demonstrates that in bivariate analysis, age > 50 years, higher educational level, availability of health insurance, longer duration of diagnosis of diabetes mellitus, and HbA1c > 7% were significantly associated with prior screening (p < 0.05).

3.8. Multivariable Logistic Regression Analysis of Factors Associated with Having Had a Previous Eye Examination (n = 998)

In multivariable logistic regression analysis (Table 8), older age (>50 years) was independently associated with lower odds of having had a previous eye examination (OR = 0.54; 95% CI: 0.31–0.96; p = 0.034), while male gender increased the odds (OR = 1.40; 95% CI: 1.06–1.85; p = 0.019). Participants without insurance were significantly less likely to have undergone an eye examination compared with those with insurance (OR = 0.31; 95% CI: 0.15–0.65; p = 0.002).

4. Discussion

There is an increase in the number of people being diagnosed with diabetes worldwide. As a result, a rise in eye complications associated with diabetes, such as diabetic retinopathy and diabetic macular oedema, is expected [21].
The majority of the participants had at least one prior examination, which aligns with a study from Saudi Arabia [17]. Only 122 (18%) respondents were diagnosed with diabetic retinopathy. This demonstrates significant differences compared to data collected from Jordan in 2008, where 64% of participants exhibited an element of diabetic retinopathy [22]. This difference could be explained by the underdiagnosis of diabetic retinopathy or self-reporting bias especially in the early stages, when the management is conservative.
Both a lack of awareness and believing that attendance should be related to symptoms could be associated with gaps in education at the time of diagnosis. When compared to other barriers, these had the highest percentages. Recommendations from healthcare professionals could act as an enabler to regular screening [23]. Accordingly, more care should be directed towards ensuring proper person–physician communication and education at the time of diagnosis. This lack of knowledge correlates with the results of a systematic review published in 2019, which found that the most consistent deterrent to screening across the majority of studies was a lack of knowledge about diabetic retinopathy [24]. On the other hand, some participants had an element of knowledge of diabetic retinopathy as a complication, but it was inaccurate and had been obtained from unreliable sources, such as social media, relatives, or friends. Some were also not convinced of the negative impact that diabetes can have on vision. Thus, it is crucial that they obtain their knowledge from trusted resources, which is also a necessary measure to consider.
Subsequently, other perceived barriers included those that made it difficult to obtain an appointment or reach a centre, such as transportation difficulties, unavailability of nearby centres, lack of insurance, unavailability of appointments, or difficulty booking an appointment. Similar results were noted in a 2013 published study, where transportation limited access to healthcare [25]. Also, lack of insurance was associated with reduced access to healthcare (p = 0.001). In the USA, before and after the implementation of the Affordable Care Act (ACA), the cost acting as a barrier to medical care decreased from 9.6% to 7% in adults [26]. A similar approach could be utilised in Jordan.
Moreover, only a minority of the participants had difficulties finding time off from work/lacked a companion to aid them in attending the appointment or were anxious about the exam results. This contradicts the findings reported in a study conducted in the UK, where its results illustrated that approximately one-third of participants had difficulties finding time off work or study to attend their appointments, 74.3% were worried that they may have diabetic retinopathy, and 63% were anxious about receiving their screening results [18].
Most of the participants that previously attended the ophthalmology clinic had no issues with it, suggesting that the service provided is good. However, discomfort following the administration of dilator drops, discomfort during the examination itself, or a long waiting time were the main issues faced. This aligns with the findings reported in the study conducted in the UK, where 64% complained about the adverse effects of the eye drops. Furthermore, those who did not attend regularly were more likely to complain that appointments occupied a significant portion of their day [18]. Some also were dissatisfied by the quality of the healthcare services (mistreatment by the staff/not receiving adequate time/not being seen by a specialist), which was associated with lower compliance. This was previously suggested by a systematic review published in 2013 that showed the negative impact of neglect on health outcomes [27].
According to multivariate analyses, younger age was independently associated with higher odds of prior eye examination; this could imply that they are more educated about the positive impact that regular reviews have on their overall well-being, which is similar to a recent study conducted in 2025 that showed that younger age groups had a superior health literacy [28]. According to bivariate analysis, having a higher level of education was associated with superior health awareness. Yet, this was expected, as it had been previously suggested [29]. Last but not least, participants with a previous level of HbA1c above 7% were more likely to have had a previous ophthalmic examination, which may reflect the referral patterns observed in clinical practice when glycaemic control is suboptimal.
Our study has several limitations that should be acknowledged. First, the study relied on questionnaire-based data. While this is effective for gathering large amounts of data, it might lack depth and is susceptible to various biases, including social desirability and self-reported and recall biases. These biases could potentially affect the validity and accuracy of the findings, as well as the reliability of participants’ responses, which could lead to the underestimation of the diabetic retinopathy prevalence in patients. Second, some patients may have inaccurately reported previously receiving intravitreal injections or laser photocoagulation for diabetic retinopathy, as these treatment methods could also be performed for other retinal disorders. To address these weaknesses, future research should incorporate alternative data collection methods, such as objective assessments. Despite these limitations, the study has multiple strengths. One key strength is that it combines barriers to eye examination that have been previously reported in multiple other studies conducted outside of Jordan into a single framework tailored to the context of Jordanians with diabetes. Moreover, we acknowledge that a hospital-based design may have limitations in capturing community-level barriers. The study was conducted at NCDEG outpatient clinics, which serve patients from different regions of Jordan and include individuals across a wide range of socioeconomic and demographic backgrounds. This setting allowed us to recruit a large and diverse sample while ensuring feasibility and data quality, with adequate statistical power for subgroup analyses.

5. Conclusions and Recommendations

This study identified several key barriers to regular diabetic retinopathy screening among individuals with diabetes in Jordan. Most notably, knowledge and perception barriers, which included lack of awareness about the need for screening and the belief that the absence of symptoms negates the need for examination, were the most reported barriers. Other reported barriers were logistical, financial, and personal.
The most prevalent barriers to diabetic retinopathy screening in Jordan are largely modifiable and primarily related to low awareness and accessibility. Therefore, public health strategies should focus on addressing these barriers to enhance healthcare for individuals with diabetes.
Based on our findings, targeted interventions focusing on patient education at the time of diabetes diagnosis, improved physician–patient communication, and addressing logistical barriers such as transportation and appointment accessibility may enhance adherence to the recommended screening practices.
