Awareness of Glaucoma and Eye Health Services Among Faith-based Communities in Kumasi, Ghana

Proportion of Angle Closure Glaucoma in Tamale, Ghana

PRCIS

In the largest clinic-based study to date, our review of 588 patients presenting with glaucoma in Northern Ghana revealed 36% of these had primary angle closure glaucoma (PACG).

OBJECTIVE

Glaucoma is the second leading cause of blindness worldwide. In Africa, glaucoma is an established public health problem, and PACG is not commonly discussed. Recognizing it is important because of its negative impact on visual morbidity, and also because its treatment is different from primary open angle glaucoma. In response to the observation of many PACG cases at the Northern Community Eye Hospital in Tamale, Ghana, we investigated the proportion of those attending with a first diagnosis of glaucoma who had PACG.

PATIENTS AND METHODS

Using the electronic records, we identified 976 patients who attended with a first diagnosis of glaucoma between January 2021 and October 2022. Of these, 588 met the inclusion criterion of a clear glaucoma subtype diagnosis.

RESULTS

Of these 316 (53.7%) had primary open angle glaucoma, 210 (35.7%) PACG, and 62 (10.5%) secondary glaucoma. Thus, over a third of presenting glaucomas had PACG.

CONCLUSION

This study highlights that PACG is present in about a third of patients presenting to our clinic in North Ghana. Our study demonstrates the importance of a clear diagnostic pathway including gonioscopy in the assessment of glaucoma patients and the consideration of wider training on angle closure glaucoma diagnosis and management.

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.

Knowledge of glaucoma and associated factors among primary glaucoma patients in Kunming, China

Background

To investigate the level of knowledge, attitude, and practices about glaucoma and associated factors among primary glaucoma patients in Kunming, China.

Methods

A hospital-based study was conducted on 93 patients from the First Affiliated Hospital of Kunming Medical University. Interviewer-administered questionnaires were used to collect data after written informed consent. Data were analyzed by SPSS 19.0. Univariate and multivariate logistic regression models were used to identify factors. A Chi-square test was used to analyze the association between knowledge of glaucoma and medication compliance, Mann–Whitney U test was performed to assess the relationship between knowledge of glaucoma and quality of life in patients with glaucoma. P-value < 0.05 was considered statistically significant.

Results

Among 93 patients, 55 (59.14%) were aware of glaucoma, 48 (51.61%) had good knowledge of glaucoma, while 45 (48.39%) had poor knowledge. Younger age and duration of glaucoma were associated positively with knowledge of glaucoma. 87 (93.54%) patients got knowledge of their disease from doctors. 79.17% of respondents could use all the anti-glaucoma medications on time, out of which 54.17% had good knowledge of glaucoma while 25.00% had poor knowledge of glaucoma. 30.56% of respondents used to stop anti-glaucoma medications on their own out of which only 9.72% had good knowledge of glaucoma while 20.83% had poor knowledge of glaucoma. Patients with good knowledge of glaucoma had lower scores on the Glaucoma Quality of Life-15 questionnaire. Thus, the compliance to anti-glaucoma medications and glaucoma-related quality of life were better in patients with good knowledge.

Conclusions

The level of knowledge of glaucoma among patients in Kunming is relatively low. Improving knowledge with suitable content for patients through effective multiple means such as the mass media rather than relying only on ophthalmologists may be a veritable first step in combating blindness from glaucoma and enhancing patients' quality of life.

Socio-demographic factors modify awareness, knowledge, and perceived risk of glaucoma in rural and urban residents in Ghana: a population-based survey

Purpose:

To evaluate the awareness, knowledge and the perception of risks of glaucoma among rural and urban dwellers in Ghana, a high prevalent country, in order to provide information for health promotion planning.

Method:

In a population-based descriptive cross-sectional survey, 1200 adults were selected from household settings, using a two-stage cluster and simple systematic random sampling. Quantitative data collection, using interviewer-administered questionnaire, was employed. Descriptive statistics were performed using chi-square, ordinal univariate, multinomial and multivariate logistic regression models used to calculate odds ratio with 95% confidence interval (CI) to identify predictive factors.

Results:

Overall, only 326 (27.2%, 95% CI = 24.6–29.7) indicated they were aware of glaucoma, whereas 331 (27.6%, 95% CI = 24.6–29.7) had ever undergone an eye screening. Low knowledge was demonstrated in 152 (46.6%, 95% CI = 41.2–52.0) and high knowledge in 99 (30.4%, 95% CI = 25.4–35.4) glaucoma-aware participants. Only 238 (19.8%, 95% CI = 17.6–22.1) of respondents presumed themselves to be at risk of developing glaucoma. Having eye examination (within the last 6 months) was positively associated with knowledge (adjusted odds ratio (AOR) = 1.413; 95% CI = 0.9–1.896) and awareness (AOR = 1.13; 95% CI = 0.938–2.449). Three levels of education (no education (AOR = 0.041; 95% CI = 0.016–0.11), primary (AOR = 0.057; 95% CI = 0.018–0.179), and middle school (AOR = 0.254; 95% CI = 0.127–0.51)) were associated with low knowledge while all levels of education were inversely associated with awareness. Perceived risk of glaucoma was also influenced by area of residence (rural (AOR = 0.344; 95% CI = 0.21–0.57)), being young (18–24 years (AOR = 4.308; 95% CI = 2.36–7.88)) and having previously undergone screening for glaucoma (AOR = 13.200; 95% CI = 5.318–32.764).

Conclusion:

The main modifiers of glaucoma awareness and knowledge were education and previous eye examination, but awareness had additional factor of area of residence. Perceived risk of glaucoma was influenced by being young and living in urban areas.

Long-term follow-up of phacotrabeculectomy surgery in Tanzania

INTRODUCTION

The glaucomas often co-exist with cataract. We previously reported a large trial of anti-scarring treatment in combined phacotrabeculectomy surgery. Long-term outcomes in an African population are extremely rarely reported. We present here the outcomes in IOP, acuity, bleb morphology and patient perceptions at 3-5-years post surgery.

METHODS

Tanzanian patients with glaucoma and visually significant cataract underwent combined phacotrabeculectomy surgery. In November 2015 an attempt was made to contact all participants in the study inviting them for a repeat examination. All who attended were given a detailed examination. A semi-structured interview in Swahili was administrated to determine patient experience and satisfaction with the surgery.

RESULTS

Sixty-eight (23%) attended for repeat review in 2015. The mean time from original surgery was 4.5-years (range 2.3-6.6-years). Overall 53 (78%) had IOP < 21 mm Hg and 29 (43%) an IOP < 16 mm Hg at final follow-up. A flat bleb at 26 and 100 days was associated with failure by IOP criteria at 4.5-years post-operatively. A vascular bleb at those time points was not any more associated with late failure than a non-vascular bleb. A majority of patients were pleased with the surgery. The cost of surgery is high but it is a price patients were willing to pay. Nearly all patients (95%) would recommend the service to family and friends.

DISCUSSION

Owing to the small proportion reviewed, our conclusions are severely limited. Phacotrabeculectomy worked well in a majority of the reviewed population long-term and is accepted by a majority of these patients as worthwhile.

Investigating the level of glaucoma awareness and perception of its risk factors in Anambra State, Nigeria

OBJECTIVES

The purpose of this study was to investigate the level of awareness of glaucoma and perception of its risk factors in Anambra State, and to examine and evaluate the health seeking behaviour of this target population and its relationship with the development glaucoma.

STUDY DESIGN

This is a qualitative study that utilised face-to-face semi-structured interviews to investigate the level of glaucoma awareness in the state.

METHODS

Purposive, non-random sampling technique was used to recruit the participants, and data were collected from 28 participants [aged 21-73 years] using semi-structured interview. The resulting data were analysed using Nvivo 10 software and Interpretative phenomenological analysis framework.

RESULTS

Of the 28 interviewees, 15 (53.6%) live in urban areas, and 13 (46.4%) live in the rural areas; 11 (39.3%) of the participants were male and 17 (60.7%) were females. In this study, people with more education, and people that live in the urban areas tend to have heard about glaucoma compared with people with less education, and who live in the rural areas; although this sample was too small to make substantive claims. Glaucoma was perceived as 'a dangerous eye disease that can cause blindness if not treated early; serious eye problem; an incurable eye problem that can eventually result to blindness, and a dangerous eye problem that can easily render a person blind'. Four a priori themes and ten emergent themes were identified.

CONCLUSIONS

There is low awareness of glaucoma in this population, and this encourages people to indulge in certain risk behaviours that could predispose them to glaucoma. Therefore, providing sustained health promotion programmes and improved eye care services could help this population immensely in the current struggle against glaucoma blindness.
