Background: Glaucoma, known as the "silent thief of sight," is a major cause of irreversible blindness worldwide. Due to its asymptomatic progression, early detection relies heavily on public awareness. In Himachal Pradesh, challenging geography, limited eye-care infrastructure and prevalent misconceptions impede timely diagnosis and management, highlighting the need for targeted assessments of community awareness. Material and Methods: A descriptive cross-sectional study was conducted among 400 adult participants across Himachal Pradesh between October and December 2024. Data were collected through a structured, validated questionnaire evaluating socio-demographic characteristics, glaucoma awareness and healthcare-seeking behaviors. Participants were recruited using convenience and purposive sampling via digital platforms (WhatsApp, Facebook). Statistical analysis involved descriptive statistics and chi-square tests using SPSS v26, adhering to ethical research protocols. Results: Participants primarily belonged to the 26-35 years age group (34.8%), had balanced gender representation (50.5% females) and predominantly resided in rural areas (56.8%). General glaucoma knowledge was adequate, with 78.5% correctly identifying optic nerve damage as a key feature. However, significant misconceptions existed regarding the asymptomatic nature of glaucoma (69.5% awareness), anatomical involvement (65.5% correctly identified optic nerve damage) and preventive nutritional factors (64.0% aware of Vitamin E benefits). Overall, 77.5% exhibited "Good" or "Very Good" knowledge, while 22.5% had "Fair" or "Poor" understanding, particularly among rural, older and less-educated groups. Conclusion: Residents of Himachal Pradesh demonstrated satisfactory basic awareness about glaucoma, yet crucial knowledge gaps persist, especially regarding its asymptomatic nature, preventive measures and risk factors. Addressing these gaps through targeted, culturally appropriate education, enhanced rural healthcare access and routine ophthalmic screenings is essential for reducing glaucoma-related blindness in the region.
Glaucoma, often termed the "silent thief of sight," is one of the leading causes of irreversible blindness worldwide, distinguished primarily by its asymptomatic progression and delayed diagnosis. Despite advancements in ophthalmic diagnostics and therapeutic interventions, glaucoma continues to pose substantial challenges globally, particularly due to limited public awareness, inadequate screening practices and misconceptions surrounding its severity and management [1-3]. Unlike other eye conditions, glaucoma's insidious nature-marked by gradual vision deterioration without pain or early recognizable symptoms-makes public awareness critically essential to early detection, timely intervention and prevention of permanent vision loss [4,5].
In India, glaucoma prevalence has steadily increased, becoming a significant contributor to visual impairment, especially among older adults. Rural communities, characterized by limited healthcare infrastructure, lower socioeconomic status and educational barriers, are disproportionately affected, often experiencing delays in diagnosis and inadequate treatment. Himachal Pradesh, with its challenging mountainous terrain and scattered rural settlements, exemplifies the complexities associated with glaucoma care delivery. Difficult geographical accessibility, limited ophthalmic facilities and widespread misinformation contribute significantly to poor glaucoma awareness and delayed health-seeking behavior in the region [6,7].
A crucial yet frequently overlooked aspect in glaucoma management is the public's understanding of the disease, its risk factors, potential consequences and the urgency of routine eye examinations. Evidence from other regions indicates that improved public knowledge directly correlates with earlier diagnoses, better compliance with treatment regimens and reduced disease-related morbidity. However, in many communities-including those in Himachal Pradesh-persistent gaps in knowledge, misconceptions and limited access to accurate, culturally sensitive information remain significant barriers [3,8,9].
Therefore, the present study aims to systematically assess the level of awareness, prevailing misconceptions and healthcare-seeking behaviors related to glaucoma among the general population of Himachal Pradesh. By identifying specific knowledge gaps and socio-demographic determinants influencing public understanding, the findings will inform tailored public health strategies and educational interventions. Ultimately, enhancing community-level glaucoma awareness is imperative for early detection, effective management and substantial reduction of avoidable blindness across the region.

The categorization of glaucoma-related knowledge among participants revealed that a substantial majority had either "Good" (41.0%) or "Very Good" (36.5%) awareness levels, suggesting a positive general foundation of knowledge in the community. However, significant concerns remain, with 17.0% exhibiting only "Fair" knowledge and 5.5% classified as having "Poor" understanding. This distribution indicates that targeted public health initiatives focusing on populations with lower education levels and rural residents are necessary to address critical knowledge gaps and misconceptions, thus improving early detection and management of glaucoma in the region (Table 3).
Table 3: Knowledge Score Classification
Knowledge Category | Score Range | Frequency (n) | Percentage (%) |
Very Good | ≥80% | 146 | 36.5 |
Good | 60%–79% | 164 | 41.0 |

This study provides comprehensive insight into the current status of public awareness, understanding and misconceptions about glaucoma among the residents of Himachal Pradesh. The findings underline a positive baseline knowledge regarding glaucoma, with the majority of respondents correctly recognizing it as a serious eye condition causing optic nerve damage and potential blindness. Nevertheless, critical gaps and misconceptions persist, particularly concerning the disease’s asymptomatic nature, specific risk factors, preventive strategies and urgency of regular ophthalmic screening.
Socio-demographic characteristics of participants provided valuable context. The balanced representation across genders and age groups, with significant participation from economically active individuals (26-45 years) and a notable number of elderly respondents, highlights that the sample accurately reflects the populations most impacted by glaucoma. Moreover, the higher proportion of rural participants (56.8%) underscores the importance of specifically addressing rural healthcare challenges, including limited access to eye-care facilities, geographical barriers, socio-economic constraints and generally lower health literacy levels. These rural populations represent an especially vulnerable group, as limited knowledge and delayed healthcare-seeking behaviors in remote regions significantly increase the risk of glaucoma-related blindness. Consequently, public health initiatives must place greater emphasis on tailored, culturally sensitive interventions within rural communities.
While respondents displayed commendable awareness about foundational aspects of glaucoma-such as its potential to cause permanent blindness (66.8%), recognition of high intraocular pressure as a primary risk factor (72.8%) and the necessity of immediate professional consultation upon vision changes (77.3%)-several concerning knowledge gaps were identified. A considerable proportion (30.5%) did not fully appreciate that glaucoma can develop silently without noticeable symptoms, a critical misunderstanding that potentially leads to delayed diagnoses and increased risk of irreversible damage. Further misconceptions emerged regarding specific anatomical structures involved, with only 65.5% accurately identifying optic nerve damage as central to glaucoma progression. Similarly, understanding the role of nutritional and lifestyle factors such as the protective role of Vitamin E (64.0%) and benefits of regular exercise (78.3%) demonstrated room for targeted public health education.
The study also highlighted inconsistencies regarding knowledge of glaucoma management. While the majority recognized the disease as incurable but manageable (84.3%), fewer participants fully appreciated the chronic nature of glaucoma treatment, particularly regarding the importance of adherence to long-term use of medications such as eye drops (68.8%). Such misconceptions may adversely affect treatment compliance and outcomes, emphasizing the necessity for clear, detailed communication in public education efforts about long-term glaucoma management strategies.
Symptom awareness was reasonably high, especially regarding urgent glaucoma-related symptoms such as sudden severe eye pain (73.5%) and peripheral vision loss (77.3%). Yet, the identification of subtle early symptoms like halos around lights or initial vision blur was relatively lower, highlighting potential risks of delayed healthcare-seeking behavior among affected individuals. Thus, enhancing public education about recognizing subtle early-stage glaucoma symptoms is critical for promoting timely clinical intervention.
The knowledge score classification provided deeper insights into the distribution of glaucoma-related awareness within the community. Although the majority exhibited either "Good" (41.0%) or "Very Good" (36.5%) knowledge, the sizeable proportions of respondents falling into the "Fair" (17.0%) and "Poor" (5.5%) knowledge categories indicate significant segments of the population remain inadequately informed. Notably, these lower-knowledge categories are often associated with socio-economic disadvantages, lower educational attainment and rural residency-factors typically correlating with limited access to health information and ophthalmic services. Targeted educational campaigns and public health interventions must therefore prioritize these vulnerable groups to ensure equitable access to essential glaucoma awareness and care.
These findings align with existing research globally and nationally, reinforcing that increased knowledge about glaucoma significantly correlates with improved preventive practices, earlier detection and better clinical outcomes. However, Himachal Pradesh’s unique geographical and socio-cultural context necessitates region-specific public health strategies. Incorporating regular vision screening into primary healthcare facilities, particularly in rural and remote settings, could facilitate early detection and timely referral for specialist care. Furthermore, leveraging community health networks (such as ASHA workers) to disseminate glaucoma-related information may effectively bridge communication gaps, dispel myths and overcome cultural resistance or fears associated with medical interventions [10-12].
Public health education should emphasize the asymptomatic, progressive nature of glaucoma and clearly communicate the urgency of regular eye examinations, especially among populations with family histories of glaucoma. Addressing prevalent misconceptions, clearly outlining available treatments, emphasizing the importance of adherence to long-term care and highlighting preventive lifestyle habits (e.g., exercise, balanced diet and eye protection) can substantially improve public perception and proactive management of glaucoma [13,14].
While residents of Himachal Pradesh exhibit generally commendable foundational knowledge of glaucoma, critical knowledge gaps and misconceptions remain prevalent, particularly among rural, older and less educated population segments. Addressing these gaps through targeted, culturally sensitive educational initiatives, improving healthcare infrastructure accessibility and promoting routine ophthalmic screenings are essential measures. Implementing these comprehensive strategies will likely enhance early glaucoma detection, encourage timely interventions and significantly reduce the preventable burden of irreversible vision loss associated with glaucoma in the region. Future research should evaluate the effectiveness of these targeted interventions and further explore socio-cultural barriers influencing glaucoma awareness and healthcare-seeking behaviors.
This study concludes that although residents of Himachal Pradesh possess generally good foundational knowledge about glaucoma, substantial gaps and misconceptions remain, especially concerning its asymptomatic progression, critical risk factors, preventive measures and the importance of timely ophthalmic evaluations. These gaps disproportionately affect rural populations, older adults and individuals with lower educational backgrounds, significantly increasing their risk of late diagnosis and irreversible vision loss. Addressing these disparities through targeted, culturally sensitive educational initiatives, integrating routine glaucoma screening into primary healthcare services and strengthening rural healthcare infrastructure will be crucial in improving glaucoma awareness and early detection. Future public health interventions should prioritize vulnerable communities to reduce glaucoma-related morbidity, ultimately decreasing the preventable burden of blindness within this geographically challenging region.
