Awareness and Knowledge of Glaucoma Among the Diabetic Population of Saudi Arabia: A Cross-Sectional Study

Eye disease knowledge and awareness among Iranian population: The Gilan Eye Study

The purpose of this study was to investigate the public knowledge regarding cataract, glaucoma, refractive error, and diabetic retinopathy among Iranian population living in Gilan province. This population-based cross-sectional study was conducted on 2588 individuals aged over 50, living in both urban and rural districts of Gilan. All participants were interviewed to determine their knowledge regarding the mentioned eye diseases. Their source of knowledge was determined whether health care professionals, family or relatives, social media, or publications. Socioeconomic status (SES) of participants was calculated based on the principal component analysis. The presenting visual acuity of all study participants was assessed by a trained optometrist. In this study, total knowledge of cataract, glaucoma, refractive errors and diabetic retinopathy was 52.1%, 2.5%, 15.1%, and 29.7%, respectively. A lower cataract knowledge was found in participants with low (odds ratio [OR] = 0.44; p = .02) and moderate SES (OR = 0.56, p = .02). We also lower knowledge of glaucoma among low (OR = 0.33; p < .001) and moderate SES group (OR = 0.48, p = .002). A higher level of knowledge about refractive error was observed in participants with normal vision (OR = 4.89; p = .011) and mild/moderate visual impairment (OR = 3.69; p = .046). Participants without a history of diabetes mellitus had less knowledge about diabetic retinopathy (DR) (OR = 0.56; p < .001), while those with more than 12 years of education had higher knowledge about DR. In conclusion, lower level of the knowledge was identified among individuals with lower levels of SES and education, while participants with better vision could be benefit from the high levels of knowledge.

Glaucoma knowledge and attitudes among diagnosed participants at a Vhembe clinic, South Africa

Background: Glaucoma remains a major public health concern worldwide. Most patients are dropping out of care, oblivious to the symptomless nature of glaucoma disease.Aim: This study aimed to investigate glaucoma knowledge and attitudes among those diagnosed with the condition in the Limpopo province (South Africa).Setting: The study was conducted at Elim Hospital in the Vhembe District of the Limpopo province, South Africa.Methods: The design of this study was cross-sectional and quantitative in approach. Those diagnosed with glaucoma and receiving eye care treatment at a district hospital in Limpopo province were purposively selected to participate in the study. Quantitative data on knowledge and attitudes towards glaucoma was collected and analysed using a self-administered questionnaire.Results: Eighty-nine purposively selected glaucoma patients, with an average age of 61.20 ± 14.77 years, participated in the study. Participants had an average knowledge score of 43 ± 20.87, with over 50% demonstrating an understanding of the importance of follow-up care, that treatment can slow the condition, and that the condition can progress rapidly if left untreated. The socio-demographic factors found to be statistically significant in relation to glaucoma knowledge were education and the duration of the condition, with p-values of 0.000 and 0.002, respectively. Concerns regarding the condition were expressed by the majority of participants, totalling 82% (n = 73).Conclusion: Awareness programmes need to be implemented to spread knowledge about the nature of glaucoma and the importance of adherence to treatment among those with low levels of education and newly diagnosed patients.Contribution: Awareness and knowledge regarding glaucoma can assist patients in treatment adherence, alleviation of the disease burden and concerns related to the eventuality of becoming blind.

Perceptions and Misconceptions About Eye Disease Treatment: A Cross-Sectional Study From Jazan, Saudi Arabia.

Eye diseases such as cataracts and glaucoma significantly contribute to vision impairment and blindness worldwide. While cataracts are the leading cause of preventable blindness, glaucoma, often referred to as the "silent thief of sight", can lead to irreversible vision loss if untreated. Despite their prevalence, awareness and understanding of these conditions remain low, particularly in regions like Saudi Arabia, where demographic changes and rising diabetes rates exacerbate the burden of eye diseases. This study aims to assess the knowledge and perceptions of cataracts and glaucoma among residents of Jazan to identify gaps and inform public health interventions. A cross-sectional online survey was conducted among participants aged 18 years and older in Jazan. The structured questionnaire assessed demographic information, awareness of cataracts and glaucoma, understanding of symptoms, and perceptions of treatment options. Data collection took place over four weeks, with statistical analysis performed using descriptive statistics to summarize findings. A total of 426 participants completed the survey. Of these, 43.9% (n = 186) were aware of cataracts, while only 28.1% (n = 119) recognized glaucoma. Awareness of cataract symptoms varied, with 43.4% (n = 184) identifying blurred vision; however, 71.5% (n = 303) reported being unaware of glaucoma. A significant majority (68.2%, n = 289) recognized surgical treatment for cataracts, but only 27.8% (n = 118) were aware of treatment options for glaucoma. High levels of uncertainty about both conditions suggest a critical lack of understanding in the community. This study emphasizes the need for improved awareness and understanding of cataracts and glaucoma in Jazan, Saudi Arabia. By implementing targeted public health strategies, healthcare providers can enhance knowledge, encourage regular eye examinations, and ultimately reduce the burden of visual impairment in the community.

Healthcare professionals' knowledge and attitudes towards polygenic risk testing for glaucoma.

Effective clinical implementation of polygenic risk testing for glaucoma relies on healthcare professionals' attitudes and knowledge of the test. Given the emerging applications of the test, it will likely impact a range of healthcare professionals and will require competency in polygenic risk scores concepts for all those involved in patient care. To our knowledge, this is the first study to assess healthcare professionals' views towards polygenic testing for glaucoma. An online cross-sectional questionnaire was distributed to healthcare professionals via relevant professional organisations in Australia. The questionnaire assessed experience and confidence with genetic testing, glaucoma and genetic knowledge, recommendations for the tests, and factors affecting the decision. A total of 94 participants completed the questionnaire. The sample was composed of ophthalmologists (36%), optometrists (21%), orthoptists (17%), general practitioners (16%) and clinical geneticists/genetic counsellors (10%). Although familiarity with polygenic risk scores for glaucoma was low overall (11%), the majority reported a positive attitude towards recommending testing based on known risk factors such as family history (91%) and older age (57%). Over 95% indicated that ophthalmologists would be the most appropriate group to order polygenic risk testing and communicate results. The majority felt they would benefit from more training on polygenic risk scores (93%). Our findings indicated that multiple groups of healthcare professionals were neither familiar nor confident with the concept of glaucoma polygenic risk testing, and identified training and education needs to support the implementation of testing into clinical practice.

Awareness and knowledge of glaucoma among adult patients of primary open-angle glaucoma at the outpatient department of ophthalmology of a tertiary care center in Western India: A cross-sectional questionnaire-based study

Abstract Background: This cross-sectional study, conducted at a tertiary eye care center between January 2016 and January 2018, aimed to assess the awareness and knowledge of primary open-angle glaucoma (POAG) among patients aged 18 years and above. Materials and Methods: This was a cross-sectional questionnaire-based study. Diagnosed cases of POAG were included. A well-structured questionnaire, validated by ophthalmologists, was administered to assess awareness and knowledge. Demographic data were collected initially, and subsequent questions determined awareness and knowledge scores. A total score of <50% indicated poor awareness and knowledge, 50%–75% indicated fair, and more than 75% indicated good. Results: Out of 972 participants, 67.6% were males, and 32.4% were females. No significant correlation was found between awareness/knowledge and age or gender (P > 0.05). However, a statistically significant correlation was observed between education status and both awareness and knowledge (P < 0.05). Overall, the majority of patients demonstrated fair awareness (50%–75%) and knowledge of glaucoma. Conclusion: This study provides valuable insights into the awareness and knowledge of POAG among a diverse patient population. The fair overall awareness and knowledge highlight the need for targeted educational interventions, particularly among individuals with lower education levels. The findings contribute to our understanding of glaucoma awareness in clinical settings, emphasizing the importance of tailored education strategies to enhance public health outcomes in glaucoma management.

Awareness and knowledge of glaucoma among the patients attending a tertiary eye hospital with and without glaucoma diagnosis

Background: Glaucoma, a leading cause of irreversible blindness, remains under-recognized in many regions, including Bangladesh. This study aimed to assess the awareness and knowledge of glaucoma among the patients attending a tertiary eye hospital with and without glaucoma diagnosis. Methods: This cross-sectional study was conducted on 300 individuals attending deep eye care foundation, Rangpur, from April 2023 to September 2023. Informed consent was obtained from eligible participants over 18 years. The questionnaire, available in both English and Bengali, collected demographic data and included questions on glaucoma awareness and knowledge. Data were analysed using SPSS 25, and the chi-square test was applied to determine statistical significance. Results: Among the participants, 34.7% had heard of glaucoma, with doctors/hospitals being the primary source of information. Awareness varied significantly based on age, residency, education, occupation, and income levels. Among those aware of glaucoma, 59.6% had poor knowledge, 33.7% had average knowledge, and only 6.7% had good knowledge. No significant association was found between glaucoma patients and non-glaucoma patients regarding knowledge level. Conclusions: This study revealed a substantial gap in glaucoma awareness and knowledge in Bangladesh. While a notable portion of the population had heard of glaucoma, their understanding of the condition was limited, emphasizing the need for targeted awareness campaigns and improved access to eye care services. Addressing these gaps is crucial for early diagnosis, treatment, and preventing irreversible blindness while reducing the economic burden associated with glaucoma-related healthcare costs.

Knowledge of Glaucoma Among New Patients to a Tertiary Eye Care Center in China.

Glaucoma patients who had previously been evaluated by eye care professionals at lower-level facilities possessed limited awareness and knowledge about their condition upon presentation to a tertiary care ophthalmic hospital, highlighting the need for improved patient education throughout the health care system. To investigate the depth of knowledge about glaucoma among patients who were referred to a tertiary eye hospital for their first visit. An internally-designed questionnaire (scored 0-15) assessing patients' knowledge about glaucoma was administered at a glaucoma outpatient service. Patients were divided into normal, high-risk, and glaucoma groups based on comprehensive eye evaluation. Scores were analyzed by regression models. The relationship between glaucoma awareness and the stage of disease at presentation was explored. One hundred and thirty patients were enrolled and divided into three groups. The group with definitive diagnosis of glaucoma had the most prior medical visits but scored the lowest, with the primary source of information being previous health care providers. The high-risk group possessed more knowledge about glaucoma than the other groups and tended to acquire knowledge from the media and sought tertiary care earlier. Significant differences were observed between the glaucoma and the high-risk groups in all aspects of glaucoma knowledge (P < 0.05). Additionally, the average scores of all participants who had visited lower-level facilities were low. Education, economic status, presence of risk factors for glaucoma positively correlated with awareness and knowledge, whereas age had an inverse relationship (all P < 0.05). Ophthalmic visit frequency had no impact (P > 0.05). Doctors were the primary source of information for all groups, but social media users were better informed. Patients at tertiary eye care centers lack glaucoma knowledge, despite experience with eye care providers previously. Implementing health education at all levels is crucial in preventing glaucoma-related visual impairment.

Evaluation of Current Artificial Intelligence Programs on the Knowledge of Glaucoma.

To measure the success of three different artificial intelligence chatbots, ChatGPT, Bard, and Bing, in correctly answering questions about glaucoma types and treatment modalities and to examine their superiority over each other. Thirty-two questions about glaucoma types and treatment modalities were asked using the ChatGPT, Bard, and Bing chatbots. The correct and incorrect answers were also provided. Accuracy rates were compared. Questions asked: ChatGPT answered 56.3%, Bard 78.1%, and Bing 59.4% correctly. There was no statistically significant difference between the three artificial intelligence chatbots in the rate of correct and incorrect answers to the questions asked (p = 0.195). Artificial intelligence chatbots can be used as a tool to access accurate information regarding glaucoma types and treatment modalities. However, the information obtained is not always accurate, and care should be taken when using this information.

Glaucoma Screening among Relatives of Glaucoma Patients in Anambra State, Nigeria

Aim: To determine the awareness, attitude, and practice of glaucoma screening among adult first degree relatives of glaucoma patients in Anambra State, Nigeria. Study Design: A prospective, descriptive, cross-sectional survey. Place of Study: Eye clinics and community eye care out-reaches that offer primary, secondary, and tertiary eye care services to people within Anambra state, Nigeria. Methods: A pretested, interviewer-administered questionnaire was used to obtain information such as sociodemographic data, awareness and knowledge of glaucoma and the frequency of practice of glaucoma screening. These were analyzed using descriptive and inferential statistics (Chi square test and logistic regression) where applicable. Level of significance was set at a p-value &lt;0.05. Results: A total of 186 first degree relatives (FDRs) of glaucoma patients participated, 120 (59.1%) were females, M: F = 1:1.4 and a mean age 43.87 years ± 14.62 SD. Almost half had a secondary level of education and were traders. Majority (83.9%) and 39.8% had heard of glaucoma and glaucoma screening respectively in the past. However, only 23.7% had been screened for glaucoma. The main reasons respondents gave why they did not screen for glaucoma include 'not necessary', 'no time' and ' not affordable. There was a significant negative relationship between unemployment and poor glaucoma screening practice p=0.007. Conclusion: This study showed a generally poor knowledge, attitude and practices towards glaucoma screening in the study population. Stakeholders need to intensify efforts to make people understand glaucoma risk factors and appreciate the need to have glaucoma screening in their environments.

Xiaoqing: A Q&A model for glaucoma based on LLMs

Glaucoma is one of the leading cause of blindness worldwide. Individuals affected by glaucoma, including patients and their family members, frequently encounter a deficit in dependable support beyond the confines of clinical environments. Seeking advice via the internet can be a difficult task due to the vast amount of disorganized and unstructured material available on these sites, nevertheless. This research explores how Large Language Models (LLMs) can be leveraged to better serve medical research and benefit glaucoma patients. We introduce Xiaoqing, a Natural Language Processing (NLP) model specifically tailored for the glaucoma field, detailing its development and deployment. To evaluate its effectiveness, we conducted two forms of experiments: comparative and experiential. In the comparative analysis, we presented 22 glaucoma-related questions in simplified Chinese to three medical NLP models (Xiaoqing LLMs, HuaTuo, Ivy GPT) and two general models (ChatGPT-3.5 and ChatGPT-4), covering a range of topics from basic glaucoma knowledge to treatment, surgery, research, management standards, and patient lifestyle. Responses were assessed for informativeness and readability. The experiential experiment involved glaucoma patients and non-patients interacting with Xiaoqing, collecting and analyzing their questions and feedback on the same criteria. The findings demonstrated that Xiaoqing notably outperformed the other models in terms of informativeness and readability, suggesting that Xiaoqing is a significant advancement in the management and treatment of glaucoma in China. We also provide a Web-based version of Xiaoqing, allowing readers to directly experience its functionality. The Web-based Xiaoqing is available at https://qa.glaucoma-assistant.com//qa.

Tackling the Silent Thief of Sight: Assessing Glaucoma Awareness, Knowledge, and Risk of Prevalence in Karachi

Background: The objective of the study was to assess understanding of glaucoma awareness and knowledge, alongside the prevalence of glaucoma and associated risk factors among the general population of Karachi, Pakistan. Methodology: This cross-sectional survey-based study determined a sample size of 384 using a z-test score at a 95% confidence interval with a margin of error of 0.05. Data were collected via questionnaire over approximately six months. Basic statistical techniques, including frequency and percentage calculations using MS Excel version 2016, were employed for data analysis. Results: Five hundred individuals participated in the survey. Glaucoma awareness was noted in 56% of respondents, with 9.6% having a confirmed diagnosis of glaucoma. Higher education, positive family history of glaucoma, and previous eye tests were significantly associated with glaucoma awareness. Media served as the primary source of glaucoma information. Higher education correlated with better glaucoma understanding, while increasing age, exposure to high-intensity light, and associated disorders were linked to a higher glaucoma prevalence. Conclusion: Glaucoma, a common eye ailment, can lead to blindness. Training medical personnel to identify symptoms and expanding public knowledge and treatment options are crucial to reducing its occurrence. Raising awareness and providing free medical care to the underprivileged can significantly enhance quality of life.

Glaucoma awareness, anxiety and its impact on patients undergoing visual field testing and optical coherence tomography.

To assess the effect of Glaucoma awareness, knowledge, and anxiety on patients under visual field analysis by Humphrey's visual field analyzer (HFA) and optical coherence tomography(OCT). This prospective comparative cohort study included glaucoma patients undergoing HFA (Group A)(n = 150) and OCT(Group B) (n = 150). Each group consisted of 75 newly diagnosed patients and 75 patients who were on follow-up. Participants completed State trait anxiety inventory form Y2(STAI) before and after the test to assess pre-test and intra-test anxiety. Another validated and structured questionnaire was used to assess patient awareness and knowledge of glaucoma. Anxiety scores were used to make correlations and comparisons between the two groups and also against visual field reliability indices. The impact of awareness on anxiety scores and its correlation with reliability indices were also determined. Overall pretest and intratest anxiety scores in patients undergoing HFA were 52.39(9.5) and 52.45(8.6)and OCT 53.04(8.0) and 53.83(8.2) respectively.Pretest anxiety was less in follow-up patients of both groups(Group A-51.04,Group B-52.72).There was no statistically significant difference between the groups(pretest p = 0.52,Intratest p = 0.15). Anxiety score was found to be significantly high in female participants(54.07,p = 0.01)and those without awareness(p < 0.001). Patients with education of graduation and above in group B had significantly lower anxiety scores(p = 0.007). Anxiety levels induced by both diagnostic modalities HFA and OCT appear to be similar and it does not affect the reliability indices.Anxiety score was higher in female participants and participants lacking disease awareness.

Patient information videos via QR codes: An innovative and sustainable approach in ophthalmology.

We explore an innovative approach by transforming patient information leaflet (PILs) into Quick Response (QR) code linked patient information videos (PIVs) in ophthalmology. Our objectives are to assess the subjective utility of a PIV on glaucoma and analyse the use of QR codes as a delivery method. A prospective study was conducted in Ninewells Hospital, NHS Tayside. A glaucoma PIV was created and linked to a QR code provided to 130 glaucoma patients. Pre- and post-video questionnaires evaluated the patients' perception of using a QR code and subjective improvement in their understanding of glaucoma. Out of 102 responses collected, 55% of patients had no prior experience with QR codes. However, 81% of patients were able to watch the PIV. The average view duration of the video was 3:26, with 82.5% view retention. Statistically significant improvement in glaucoma knowledge was observed across all six areas questioned (p < 0.001) using a 5-point Likert scale. Overall, 70% of patients preferred PIVs over PILs, and 77% acknowledged that PIVs could be a sustainable alternative. QR codes for delivering PIVs were well-received, with patients finding them easy to use. Our PIV on glaucoma effectively enhanced patients' understanding of the condition.

Factors limiting glaucoma care among glaucoma patients in Nigeria: A scoping review.

Glaucoma currently accounts for 11% of irreversible visual loss worldwide. Due to many factors, patients do not access the glaucoma care pathway and present late with poor vision, while many are undiagnosed or untreated. These factors may be personal-level dispositions or Institutional-level dispositions, limiting the awareness, diagnosis, and treatment of glaucoma or adherence to medications or follow-up clinic visits. This scoping review followed the JBI methodology for scoping reviews and was pre-registered on the open science platform (https://osf.io/wqx57/?view_only=727eb6c803764509a2809e5d0794e214). The PUBMED, EMBASE, WEB OF SCIENCE, AJOL, and GOOGLE SCHOLAR databases were systematically searched for studies published in English between 1990 and June 2023. Data were extracted and analysed along a conceptualised framework of factors limiting access to glaucoma care in Nigeria. Of the 336 records retrieved, 13 studies were included in this scoping review. These included one (1) mixed method (quantitative/qualitative) study, three qualitative studies, and nine quantitative studies spanning 2008-2022 covering eight states and 2,643 sampled respondents. Nine studies reported personal-level dispositions limiting glaucoma care, including low levels of education, unemployment, gender, living distance from the hospital, cost of care, and faith/religion. Four reported institutional-level dispositions, including the lack of proper equipment and expertise to diagnose or manage glaucoma. The factors limiting Glaucoma care in Nigeria are varied and may act alone or combined with other elements to determine the awareness or knowledge of glaucoma, uptake of glaucoma surgery, medication adherence, or clinic follow-up. While most of these factors limiting glaucoma care in Nigeria may be amenable to policy, a bottom-up approach is needed to improve the community's awareness and uptake of glaucoma services. A shift from the over-dependence and reliance on tertiary hospitals, which are often far away from the people who need them, is required to bridge the information and service gap currently being witnessed.

A PHARMACIST INTERVENTION ON KNOWLEDGE AND ADHERENCE IN PATIENTS WITH OPEN-ANGLE GLAUCOMA

Objective: The objective of the study is to assess the pharmacist’s intervention on knowledge and adherence in patients with open-angle glaucoma therapy. Methods: The study was conducted at the glaucoma outpatient department of Shree Rana Ambika Shah Eye Hospital, Rupandehi, Nepal. Census sampling was performed among the glaucoma patients meeting the inclusion criteria from August 2018 to November 2018. Data were collected using a structured questionnaire that included questions about demography, knowledge of glaucoma, medication adherence, and factors associated with medication non-adherence to glaucoma therapy. Each patient was counseled by a pharmacist, and the relevant information was provided in the form of an information leaflet. Knowledge level and adherence level were re-assessed during the follow-up visit after 1 month. The Morisky–Green–Levine medication adherence scale was used to assess adherence. Results: A total of 103 patients were enrolled in the study, and the majority of the patients were of age ≥59 years. After intervention by the pharmacist, the knowledge level on glaucoma improved from poor to good. Before intervention, about 31% of patients were adherent to the medication therapy, but after intervention, about 73% of patients were adherence to the medication therapy. There was a significant difference in the mean of the knowledge level score and the mean of the medication adherence score before and after intervention. The common causes of non-adherence were reported to be forgetfulness, a stressful life, and difficulties with medication time. Conclusion: The study demonstrates that pharmacist intervention is effective in improving both knowledge and medication adherence to open-angle glaucoma therapy.

Investigation of Knowledge, Awareness, and Practices of Glaucoma in Riyadh City, Saudi Arabia.

Background Glaucoma is a group of conditions characterized by progressive irreversible optic neuropathy, intraocular pressure as a modifiable risk factor, and, in many patients, visual field defects. Glaucoma has recently been classified as a neurodegenerative disorder of the optic nerve that results in the loss of retinal ganglion cells. This study evaluated levels of awareness of glaucoma in the general population of Riyadh City, Saudi Arabia. Methodology A pre-designed, pre-validated online questionnaire from previous studies was distributed to respondents via online social media platforms. Factors associated with awareness of glaucoma were analyzed statistically. Results Responses were received from 585 participants aged ≥18 years, including 309 (52.8%) men and 276 (47.2%) women. Gender, a diagnosis of glaucoma, a positive family history of glaucoma, and undergoing glaucoma screening were significantly associated with the level of glaucoma knowledge (p < 0.05 each). Age group (p = 0.587) and level of education (p = 0.136) were not significantly associated with the level of glaucoma knowledge. Conclusions The population of Riyadh City exhibited a low level of glaucoma awareness, indicating an urgent need for comprehensive ophthalmic health education initiatives aimed at enhancing public consciousness and awareness of glaucoma risks and complications.

Glaucoma among Saudi Arabian population: a scoping review.

Despite its high risk of leading to permanent visual dysfunction, glaucoma remains underdiagnosed in primary care settings. About 11% of glaucoma patients in Saudi Arabia end up with bilateral blindness. This scoping review investigates and presents results on the glaucoma profile, including its prevalence, knowledge, attitude, and practice of Saudi Arabians towards the disease. An online search using four databases through online software (www.rayyan.ai) was performed to extract the relevant articles. Out of 76 records, 21 articles were eligible for the analysis. All included studies were published between the years 2014 and 2022. Most studies were in Riyadh city, followed by Jeddah. All participants (n=11 388) were adults >18 years old, and male participants were generally higher than females. The findings showed poor knowledge of glaucoma among the general population, while the knowledge among glaucoma patients was acceptable. The attitude was positive, while the compliance and practice were fair. More educational programs about glaucoma, its risk to the eyes, and the overall quality of life are highly recommended.

Decomposition of socioeconomic inequalities in glaucoma knowledge in Taiwan.

Glaucoma knowledge is strongly associated with medication adherence and preventive behavior. Studies have frequently reported socioeconomic inequalities in glaucoma knowledge. This study aimed to decompose such inequalities. Decomposition analysis enables the design of policies directly targeting the underlying causes of inequality. We performed a cross-sectional survey from January 1, 2019 to June 30, 2019, at the departments of ophthalmology of 2 medical centers belonging to a hospital chain in northern Taiwan. Socioeconomic inequalities in glaucoma knowledge were ranked based on 3 aspects of socioeconomic status (SES): (1) education, (2) income, and (3) self-perceived financial status. The concentration index was calculated and decomposed using decomposition analysis. Elasticity and marginal effects were estimated for each decomposed factor. In total, 1,203 patients completed the survey. Both measures of glaucoma knowledge and overall glaucoma knowledge score significantly contributed to the progressivity of knowledge inequalities (pro-high-SES inequalities). The concentration index for overall knowledge score with respect to education was 0.166 (p<0.001). Both objective and subjective measures of SES were associated with pro-high-SES inequalities. Our decomposition analysis revealed that demographic factors and attitudinal factors such as the level of concern regarding developing glaucoma contributed significantly to SES-based inequalities in glaucoma knowledge. Our decomposition analysis provided empirical evidence regarding the underlying causes of SES-based inequalities in glaucoma knowledge. Efforts to improve glaucoma knowledge should consider specific factors that drive SES-based inequalities, such as age, sex, and concern about vision health, to ultimately achieve low SES-based inequalities.
