Moore SG, Richter G, Modjtahedi BS. Factors Affecting Glaucoma Medication Adherence and Interventions to Improve Adherence: A Narrative Review. Ophthalmol Ther 2023; 12:2863-2880. [PMID: 37698824 PMCID: PMC10640536 DOI: 10.1007/s40123-023-00797-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2023] [Accepted: 08/15/2023] [Indexed: 09/13/2023] Open
Abstract
Glaucoma is a leading cause of vision loss. First line therapy for primary open angle glaucoma (POAG) are topical ocular hypotensive drops. Patient adherence with topical therapy for glaucoma is a significant challenge with a reported adherence of 60%. The purpose of this review is to discuss factors associated with glaucoma adherence (including demographic factors, cost, patient education, health beliefs, treatment burden and regimen, and physical limitations) and to explore potential interventions to improve medication adherence. Articles included in this review were found by searching PubMed and Google Scholar using the key words "Glaucoma Treatment Adherence" and "Glaucoma Treatment Compliance." Data from this review demonstrates that higher medication cost, lower patient education/literacy levels, and being of African and Hispanic descent are associated with lower medication adherence rates. The data is inconclusive on whether medication regimen complexity lowers patient medication adherence rates. Interventions that have successfully improved medication adherence rates for minority patients have focused on building trust and addressing fears and false beliefs. For cost, explicit physician communication to patients regarding medication cost is important and can help the physician determine any patient concerns about cost. Outside the USA, adherence has been improved through adherence-contingent rebate systems and government subsidies. Most interventions that aim to increase adherence target patient education and literacy with the following interventions demonstrating efficacy: written instructions targeting glaucoma-specific health literacy, literacy level appropriate glaucoma education videos, and interactive and personalized educational programs. More clinic infrastructure and programs that utilize patient reminder tools and patient educators could help physicians and patients in support of these personalized action plans.

[PMID: 36971785 DOI: 10.1007/s11845-023-03351-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2023] [Accepted: 03/20/2023] [Indexed: 03/28/2023]
Abstract
BACKGROUND The Age-Related Eye Disease Study 2 (AREDS 2) proved the benefit of vitamin and mineral supplementation in preventing advanced age-related macular degeneration (AMD). AREDS 2 supplements are indicated for patients with either bilateral intermediate AMD (AREDS category 3) or unilateral neovascular AMD (AREDS category 4). AIMS The aims of this telephone survey were to identify the rate of adherence of patients to AREDS 2 supplements and the factors associated with non-compliance in these patient groups. METHODS A patient telephone survey was conducted in an Irish tertiary care hospital. Patients were identified by chart review, and their AREDS categorization was reconfirmed. A telephone consultation was conducted with each patient to assess their compliance with the micronutrient supplements. RESULTS We identified 120 patients who met the AREDS criteria for supplementation. Of these, 103 patients were graded as category 4, and 17 patients were graded as category 3. Almost a fifth (18%) were current smokers. Under two-thirds (60%) of the patients were taking AREDS 2 supplements. Of the remainder, 83% of patients did not recall being advised of their benefit. The cost was cited by 10% of patients as a reason for non-compliance. CONCLUSION The ophthalmologist not only has a duty of care to treat the neovascular complications of AMD, but they must also strive to improve patient compliance with AREDS supplements. The cessation of smoking needs to be actively promoted in order to stop preventable vision loss in patients with AMD.

Abstract
Purpose To evaluate the impact of a nurse-led glaucoma education program on patient knowledge and compliance levels in an Asian population. Materials and Methods A 1-year prospective case series involving 69 adult glaucoma patients. Each patient attended a standardized nurse-led glaucoma education session. A questionnaire was administered by a single nurse-clinician and analyzed at three time points (preeducation for baseline, immediately posteducation, and at the 1-year follow-up) to evaluate for associations with patient knowledge and compliance motivation levels. Results A total of 64 patients were included in the final analysis. Patients with higher educational qualifications or who were employed had better baseline knowledge of glaucoma. Younger patients had higher baseline compliance motivation levels. Immediately posteducation, both median patient knowledge score and compliance motivation levels had a statistically significant increase. Patients on more glaucoma eye drops had greater immediate improvement in confidence in eye drop application. Patients with more positive Humphrey visual field mean deviation values had a greater immediate improvement in confidence in their understanding of glaucoma. A total of 34 patients were readministered the questionnaire at the 1-year time point. Median score for patient knowledge was highest at this point. Employed patients demonstrated better patient knowledge at baseline and at 1-year time point compared to unemployed patients. Unemployed patients experienced a significant improvement in scores from baseline to immediately posteducation, but improvement from immediately posteducation to the 1-year time point was insignificant was insignificant. Conclusion Our study has examined the effectiveness of a nurse-led glaucoma education program in an Asian population, demonstrating improvement in both patient knowledge and compliance motivation levels up to 1 year after intervention.

Abstract
Ocular formulations should provide an effective antibiotic concentration at the site of infection to treat bacterial eye infections. However, tears and frequent blinking accelerate the drug clearance rate and limit drug residence time on the ocular surface. This study describes a biological adhesion reticulate structure (BNP/CA-PEG) consisting of antibiotic-loaded bioadhesion nanoparticles (BNP/CA), with an average 500-600 nm diameter, and eight-arm NH2-PEG-NH2 for local and extended ocular drug delivery. This retention-prolonging effect is a function of the Schiff base reaction between groups on the surface of BNP and amidogen on PEG. BNP/CA-PEG showed significantly higher adhesion properties and better treatment efficacy in an ocular rat model with conjunctivitis in comparison to non-adhesive nanoparticles, BNP, or free antibiotics. Both in vivo safety experiment and in vitro cytotoxicity test verified the biocompatibility and biosafety of the biological adhesion reticulate structure, indicating a promising translational prospect for further clinical use.

Abstract
Current glaucoma treatments aim to lower intraocular pressure, often with topical ocular hypotensive medications. Unfortunately, the effectiveness of these medications depends on sustained patient adherence to regimens which may involve instilling multiple medications several times daily. Patient adherence to glaucoma medications is often low. Recent innovations in digital sensor technologies have been leveraged to confirm eyedrop medication usage in real-time and relay this information back to providers. Some sensors have also been designed to deliver medication reminders and notifications as well as assist with correct eyedrop administration technique. Here, we review recent innovations targeted at improving glaucoma medication adherence and discuss their limitations.

Abstract
PURPOSE To evaluate changes in the medication adherence of glaucoma patients during the COVID-19 pandemic and the factors influencing medication adherence. MATERIALS AND METHODS This cross-sectional study included a total of 197 glaucoma patients who were followed for at least six months in the Glaucoma Unit of the Ophthalmology Department of Inonu University, Faculty of Medicine. Patients were given a 28-item questionnaire, including the eight-item Morisky Medication Adherence Questionnaire, to evaluate medication adherence. Demographic and clinical data were recorded. P<0.05 was considered statistically significant. RESULTS Interruption of glaucoma clinic visits during the pandemic was reported by 82 (41.6%) patients. Nonadherence was reported by 56 patients (28.4%) (95% confidence interval: 22.1-34.7). For these patients, the most common reasons for nonadherence were forgetfulness (50%), the inability to receive a prescription for the drug (10.7%) and being busy (10.7%). Factors influencing nonadherence were determined to be younger age, female gender, interruption of glaucoma clinic visits and high-income levels (P˂0.05). CONCLUSION Interruption of glaucoma clinic visits during the COVID-19 pandemic and the resulting inability to have medications prescribed resulted in patient nonadherence with medication use.

Abstract
The glaucomas form a heterogenous group of conditions, which collectively account for one of the most common irreversible causes of blindness worldwide. The only treatment, for which there is evidence, to stop or slow glaucomatous disease progression is to lower intraocular pressure (IOP); this is most often initially achieved with topical medication. Adherence to anti-glaucoma therapy is known to be low even when compared with adherence to therapy for other chronic conditions. We performed a PubMed search to review evidence as to how adherence to and persistence with anti-glaucoma medications might be improved. Approaches to improving adherence include technological (such as using smart drop bottles or automated reminders) use of instillation aids, improving communication with patient education and improving tolerability of eye drop formulations. There is limited short-term evidence that automated reminders can be effective and, unfortunately, instillation aids have not proved to be efficacious with respect to improving adherence. A range of factors have been identified which affect adherence and persistence, although only a multi-faceted approach has proven evidence of efficacy, compared to improved patient education alone. There is now a wider range of available preservative-free eye drops, which have been shown to be non-inferior in achieving IOP control, with fewer side effects and improved short-term adherence. Further studies relating to adherence are warranted, particularly given the projected increase in glaucoma prevalence worldwide.

Abstract
Eye-drop formulations should hold as high a concentration of soluble drug in contact with ocular epithelium for as long as possible. However, eye tears and frequent blinking limit drug retention on the ocular surface, and gelling drops typically form clumps that blur vision. Here, we describe a gelling hypotonic solution containing a low concentration of a thermosensitive triblock copolymer, for extended ocular drug delivery. On topical application, the hypotonic formulation forms a highly uniform and clear thin layer that conforms to the ocular surface and resists clearance from blinking, significantly increasing the intraocular absorption of hydrophilic and hydrophobic drugs and extending the drug–ocular-epithelium contact time with respect to conventional thermosensitive gelling formulations and commercial eye drops. We also show that the conformal gel layer allows for therapeutically relevant drug delivery to the eyeball’s posterior segment in pigs. Our findings highlight the importance of formulations that conform to the ocular surface prior to viscosity enhancement, for increased and prolonged ocular-surface contact and drug absorption.

Abstract
OBJECTIVE The aim of this study was to evaluate patients' dissatisfaction with overall and specific aspects of a tertiary glaucoma service and to determine their independent factors, including intraocular pressure (IOP) and visual acuity (VA). METHODS Patients, aged ≥21 years, from a specialist glaucoma service in a tertiary eye hospital in Singapore for at least 6 months, were recruited for this cross-sectional study between March and June 2014. All consenting patients completed a 7-area glaucoma-specific satisfaction questionnaire and one item related to satisfaction with overall glaucoma care. We determined the top three areas of dissatisfaction and overall dissatisfaction with the glaucoma service. We also explored the independent factors associated with overall and specific areas of patients' dissatisfaction with their glaucoma care, including VA and IOP by using logistic regression models. RESULTS Of the 518 patients recruited, 438 (84.6%) patients completed the study. Patients' dissatisfaction with the overall glaucoma service was 7.5%. The three areas of glaucoma service with the highest dissatisfaction rates were as follows: 1) explanation of test results (24.8%); 2) explanation of glaucoma complications (23.7%); and 3) advice on managing glaucoma (23.5%). Patients who were dissatisfied with the overall service had a worse mean VA compared with satisfied patients (logarithm of the minimum angle of resolution =0.41±0.43 vs 0.27±0.49, p=0.005), whereas mean IOP remained well-controlled in both the groups (13.55±2.46 mmHg vs 14.82±2.86 mmHg, p=0.014). In adjusted models, factors associated with overall dissatisfaction with glaucoma care included a pre-university education and above (odds ratio [OR] =8.06, 95% CI =1.57-41.27) and lower IOP (OR =0.83, 95% CI =0.71-0.98). CONCLUSION Although less than one tenth of glaucoma patients were dissatisfied with the overall glaucoma service, one in four patients were dissatisfied with three specific aspects of care. A lower IOP, ironically, and education level were associated with overall dissatisfaction. Improving patients' understanding of glaucoma test results, glaucoma complications, and disease management may increase patient satisfaction levels.

Abstract
BACKGROUND Poor adherence to treatment is a problem in glaucoma, and patient dissatisfaction with topical glaucoma medication is a barrier to adherence. The objective of this study was to evaluate glaucoma patients' satisfaction with fixed-combination bimatoprost/timolol ophthalmic solution (BTFC). METHODS This observational, multicenter study was conducted in China in adults with glaucoma treated with BTFC for 1-3 months. Five hundred patients answered a questionnaire concerning their demographic characteristics, history of glaucoma and topical glaucoma treatment, and use of BTFC. The primary endpoint was patient satisfaction with BTFC assessed on a 10-point scale (1= very dissatisfied, 10= very satisfied). RESULTS Patients received BTFC alone (65%) or with other treatments (35%), most commonly a carbonic anhydrase inhibitor. Most patients (87%) used BTFC as a replacement for other medication, usually a β-blocker or prostaglandin analog; 13% received BTFC as add-on treatment. Key reasons for initiating BTFC therapy were poor efficacy of previous treatment (72% of patients) and side effects of previous treatment (32% of patients). Most patients agreed or very much agreed that BTFC provided better control of intraocular pressure (85% of patients), had a simpler administration (87% of patients), and was associated with better tolerance and comfort (82% of patients) compared with their previous treatment. Mean satisfaction scores were significantly higher for BTFC than for previous treatments among all patients (7.8 versus 6.0; P<0.0001) and within patient subgroups based on demographic characteristics, pattern of BTFC use, and previous treatment. CONCLUSION Patients were highly satisfied with BTFC used alone or concomitantly with another topical medication. Patients previously treated with a β-blocker, prostaglandin analog, carbonic anhydrase inhibitor, α-adrenergic agonist, or combination of two medications were more satisfied with BTFC than with their previous treatment. Most reported that intraocular pressure control, tolerability, and ease of administration improved with BTFC.

Abstract
BACKGROUND Asymptomatic in its early stages, glaucoma is the second leading cause of blindness worldwide. While psychosocial factors are taken into consideration for a host of diseases such as cancer, heart disease and autoimmune conditions, to date, psychological issues have been ignored in the clinical management of glaucoma. OBJECTIVE This work reviews the most relevant contributions from a health psychology perspective for the assessment and treatment of glaucoma, which is emerging in the field of psycho-ophthalmology. METHOD To provide scientific evidence regarding contributions of psychology to the comprehension of glaucoma, a bibliographic review of three databases (Psicodoc, PsycInfo and Medline) was conducted, spanning the period between 1940 and 2016. RESULTS This review yielded a total of 66 studies published in the period analysed and identified three areas where health psychology has made substantive contributions to glaucoma screening, monitoring and treatment: the emotional impact on patients suffering from glaucoma, the adherence to treatment and the effects of stress on intraocular pressure. CONCLUSIONS A health psychology approach for research and therapy of glaucoma must focus on the management of the negative affect associated with the diagnosis, the optimisation of treatment adherence and the stress management of the intraocular pressure measurements.

Abstract
BACKGROUND Although glaucoma is the lead cause of irreversible blindness globally, the condition shows no signs or symptoms until later stages. Knowledge about the disease is known to influence utilization of eye screening services. This study aimed at understanding knowledge and perception of risk for glaucoma, as well as eye screening behaviour among residents of Abokobi, a peri-urban community. METHODS This was a cross-sectional study that employed quantitative data collection methods, with the use of a questionnaire. Descriptive statistics were used to describe the socio-demographic characteristics, knowledge about glaucoma and eye screening behaviour. Also, associations between socio-demographic factors and awareness as well as perception of risk were analysed using Chi-square test or Univariate Fisher's exact test. RESULTS Out of a total of 300 respondents, 60.3 % were females and 39.3 % were aware of glaucoma. Majority (99.1 %) of respondents aware of glaucoma also agreed the disease can result in blindness with only (28 %) affirming that blindness from glaucoma is irreversible. Nearly half (49.7 %) of the respondents perceived themselves to be at risk of developing glaucoma. The results showed that age and education (p <0.0001) were statistically significant with glaucoma awareness. Approximately, 20.7 % of the respondents have had their eye screened with just a few (4.3 %) screening for glaucoma. CONCLUSION Although glaucoma awareness was high, the findings display inadequate knowledge about glaucoma. There is a need to effectively inform and educate people about the disease.

Abstract
PURPOSE To compare Moorfields regression analysis (MRA), Glaucoma probability score (GPS), and different discriminant functions to predict future visual field conversion of patients with ocular hypertension and early glaucoma. PATIENTS AND METHODS The study included 120 eyes of patients with ocular hypertension and 110 eyes of patients with early glaucoma from the Erlangen glaucoma registry. Annually, all patients underwent standard automated perimetry, 24-hour intraocular pressure profile, optic disc photography, and HRT (Heidelberg Retina Tomograph I-III; Heidelberg Engineering) measurements. The cohort was divided into 2 groups based on the development of repeatable glaucomatous visual fields. Positive predictive values and negative predictive values were compared for MRA, GPS, and the classification of Bathija, Iester, Mardin, and Mikelberg at baseline. Kaplan-Meier Survival curves and Logrank tests were used to evaluate equality of survival distributions for different test results. RESULTS Median follow-up was 9.04 years. 26 eyes (11.3%) demonstrated glaucomatous visual field loss in the follow-up. MRA temporal-superior and temporal-inferior outside normal limits were predictive of future visual field loss with positive predictive values of 33.3% and 28.6%. Normal GPS Temporal Sector demonstrated a negative predictive value of 96.4% and normal results in discriminant functions between 94.7% and 95.5%. CONCLUSIONS Confocal scanning laser tomography is a useful imaging modality to predict future visual field conversion. Development of visual field defects in 10 years is highly unlikely, if GPS classification and/or classification of discriminant analysis at baseline are normal. MRA temporal-superior and temporal-inferior outside normal limits are associated with future VF conversion (ClinicalTrials.gov number, NCT00494923).

Abstract
BACKGROUND In Nigeria, glaucoma has a high prevalence and is the second cause of blindness among adults after cataract. People with glaucoma frequently present very late with advanced disease, and acceptance of and adherence to treatment is low. The purpose of the study was to explore how patients' understand and respond to glaucoma in order develop an intervention to improve adherence to treatment. METHOD Hospital based qualitative study. Six focus group discussions were held with patients with advanced disease and who had either undergone glaucoma surgery, were receiving medical treatment, or had neither surgery nor medical treatment. Two traditional healers who treat eye conditions were interviewed. Audio files were transcribed, translated into English and recurring themes coded and categorized as the impact of vision loss, and understandings of the disease and its management. RESULTS Visual loss impacted significantly on the lives of people with glaucoma in many ways. Many heard the term "glaucoma" for the first time during the study. Local terms to describe the symptoms included Hawan jinin ido ("hypertension of the eye"). Patients sought treatment in pharmacies, or with traditional healers who had different interpretations of glaucoma and its treatment to biomedical understandings. Cost and forgetfulness were the main reasons for low adherence to treatment while fear was a reason for not accepting surgery. Lack of money and negative staff attitudes were reasons for low follow up. CONCLUSION Halting the progression of glaucoma is possible with treatment but the condition will remain a "silent thief of sight" in West Africa unless awareness, uptake of services and adherence to treatment improve. Understanding how glaucoma is locally conceptualised, lived with and responded to by patients is essential to aid the design of interventions to prevent glaucoma blindness in Africa. Findings have been used to adapt a motivational interviewing intervention, which is being evaluated in a clinical trial.

Abstract
PURPOSE To evaluate the compliance of glaucoma patients to medical treatment and its impact on the intraocular pressure (IOP) and to verify the associated risk factors for noncompliance. METHODS All recruited patients were examined at the ophthalmology clinics of King Abdulaziz University Hospital, Riyadh, Saudi Arabia between May and August 2012. Patients were interviewed and subjected to answer a questionnaire that was developed based on a pilot test. Collected data included age, gender, number of prescribed drugs, and different reasons for noncompliance to the prescribed drugs. RESULTS Noncompliance was detected in 18 (19.4%) of the recruited patients. Factors associated with noncompliance demonstrated a trend toward older patients, males, patients with lower IOP at presentation, higher cup to disc ratio, and drug self-administering patients. However, the only statistically significant characteristic was being under lifelong medications (P = 0.005). CONCLUSION Noncompliance was detected in around one-fifth of our glaucoma patients, particularly, the older group. Awareness programs, maintaining good patient-physician relationship, and personalizing treatment can lead to better adherence to treatment.

Abstract
Glaucoma is a leading cause of visual morbidity throughout the world and is an age-related condition, the prevalence of which rises significantly with increasing age. Glaucoma, a condition affecting the optic nerve, has a variety of subtypes with multiple aetiological factors, the most important of which are intraocular pressure (IOP) and increasing age. Treatment by lowering of IOP is the only current method, for which there is evidence, by which the rate of progressive visual deterioration can be slowed or halted. Although there are surgical and laser treatments that are efficacious in lowering IOP, the most common manner in which patients with glaucoma control their IOP is with administration of daily topical ocular hypotensive drugs (eye drops). The variety of topical drugs utilised in the management of glaucoma all have the potential to have adverse effects and/or interactions with concomitant medications, many of which may be used for other age-related conditions. Adherence with appropriate medicines has a major effect on the outcome of medical conditions and this aspect applies to the management of glaucoma. There are certain specific issues that relate to the administration of topical agents, with respect to both adverse effects and adherence. Although many suspect poor adherence in elderly patients with glaucoma, relative to younger patients, adequate evidence for this is lacking. Furthermore, the manner by which adherence issues could be improved remains inadequately understood and poorly addressed. The aims of this article were to review, from a clinical perspective, the medical therapies currently used for glaucoma and discuss adherence issues with respect to the population of patients with glaucoma, who tend to be relatively elderly.

Analysis of Factors Affecting Patients' Compliance to Topical Antiglaucoma Medications in Egypt as a Developing Country Model. J Ophthalmol 2015; 2015:234157. [PMID: 26167292 PMCID: PMC4488247 DOI: 10.1155/2015/234157] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2015] [Revised: 06/02/2015] [Accepted: 06/03/2015] [Indexed: 11/17/2022] Open
Abstract
Purpose. To study factors affecting patients' compliance to antiglaucoma medications in Egypt where there are unique factors as a developing country. Patients and Methods. A cross-sectional descriptive study on 440 Egyptian patients with open angle glaucoma (OAG) recruited for over two years. The patients were thoroughly interviewed about their age, education level, duration of glaucoma, difficulty in instilling the drops, medication regimens, a family history of glaucoma, knowledge of the disease, and the presence of medical insurance. Results. 236 (53.6%) were noncompliant compared to 204 (46.4%) who were compliant. Females had a tendency for higher compliance (p=0.061). Patient age above 50 years and low level of education and negative family history of glaucoma were factors significantly associated with poor compliance (p < 0.0001). Polytherapy and lack of medical insurance could be contributing factors. Conclusion. Egyptian patients have a high rate of noncompliance compared to the average in literature. Great effort is needed in educating patients about the importance of medications and the risk and the prognosis of this disease. Economic factors must also be taken into consideration in developing countries with large number of poor patients. We recommend simplifying drug regimens, incorporating electronic dose monitors, and creating reminders for follow-up visits of glaucoma patients.

Abstract
BACKGROUND Glaucoma is a chronic and serious disease calling for consistent lifelong therapy. The patient's compliance requires that he/she be well informed about the disease. The purpose of the present study was to determine the level of knowledge about glaucoma, and compare young patients with older ones as well as glaucoma patients with nonglaucoma ones. METHODS A total of 1110 questionnaires were distributed to patients and their relatives at the outpatient eye clinic of Hietzing Hospital (Vienna), of which 1041 were returned. The questionnaire comprised 18 questions. Patients were divided into two groups: group 1 consisted of those aged 18-60 years, while group 2 consisted of those older than 61 years. RESULTS In total, 941 questionnaires were evaluated; 72.8% of the respondents were older than 60 years, and one-half of the respondents had glaucoma (51%). The majority of patients had "moderate knowledge" of the disease (41.87%), followed by "poor knowledge" (32.52%). Glaucoma patients had considerably better knowledge of the disease (p < 0.01) than did nonglaucoma patients. Younger patients were significantly better informed than older ones (p < 0.01). Nonglaucoma patients with a positive diagnosis of glaucoma among their circle of friends or family were significantly better informed (p < 0.01) than those without such persons in their circle of friends. CONCLUSION Persons with glaucoma are much better informed about the disease than nonglaucoma patients, but the general level of knowledge is very low. Notably, younger patients were better informed than older ones. The present study, comprising a large number of patients, revealed poor knowledge of glaucoma among patients with the disease and especially among nonglaucoma patients in Vienna.

Abstract
The awareness, perceptions and experiences of Nigerian Primary Open Angle Glaucoma (POAG) patients were assessed using a hospital based cross-sectional study design. One hundred and twenty POAG patients attending a glaucoma clinic in Lagos Nigeria were recruited consecutively. They underwent face-to-face interviews with trained interviewers using a semi-structured questionnaire and an interview guide consisting of open-ended questions. A comprehensive ocular examination which included static automated perimetry, gonioscopy, stereoscopic optic nerve head assessment and contrast sensitivity was carried out for all participants. Twenty per cent (n = 24) of the respondents did not know they were being managed for a disease called Glaucoma. Age, gender, religion, ethnicity, marital status and occupation did not significantly affect the awareness of glaucoma diagnosis (p > 0.05). Positive family history of glaucoma, educational status and duration of disease were the most significant factors associated with awareness of glaucoma diagnosis (p < 0.05). POAG patients in Nigeria lack the depth of perception that can equip them to educate and motivate their family members to screen for glaucoma. There is an urgent need to develop continuous eye health education programmes to improve their perception and outlook; thereby increasing the uptake of glaucoma screening by first degree relatives of glaucoma patients.

Abstract
PURPOSE To determine adherence rates and beliefs about glaucoma and its treatment in white Americans, African Americans, white Australians, and Singaporeans of Chinese descent. PATIENTS AND METHODS Cross-sectional study of 475 glaucoma patients using topical eye drops for at least 6 months. The sample consisted of white Americans (n=133), African Americans (n=58), white Australians (n=107), and Singaporeans of Chinese descent (n=117). Self-reported adherence and beliefs about glaucoma and its treatment were assessed using the Reported Adherence to Medication scale, the Brief Illness Perception Questionnaire, and the Beliefs about Medicines-Specific Questionnaire. RESULTS Accounting for sociodemographic differences, significant differences in self-reported adherence rates were identified (P<0.001). White Americans and Australians reported significantly higher adherence (65.4%, 67.7% reported complete adherence) than African Americans or Singaporeans (56.9%, 47.5%, respectively; P<0.05). Beliefs about glaucoma treatment were predictive of adherence only in the Australian and white American samples (P<0.05). CONCLUSIONS In western cultures, attempts to improve adherence may benefit from greater examination of individual's concerns about, and perceived need, for glaucoma treatment. Further studies are needed to identify the critical predictors of adherence in nonwestern cultures and to validate measures in these populations.

Abstract
Background The aim of this study was to investigate the intensity of side effects that patients attribute to their topical glaucoma medication and their relationship to adherence behavior. Methods This was a questionnaire-based study of 123 glaucoma patients at a university eye clinic in Erlangen, Germany. An initial questionnaire asked about patient demographic data, the treatment plan, and intensity of side effects, and included Adherence to Refills and Medication Scale 2 (ARMS2) and visual analog scale (VAS-AD) scores. In a follow-up questionnaire, the treatment plan, intensity of side effects, ARMS2, and VAS-AD were reanalyzed. Results Most patients reported having few side effects, although only 20% said that they had no symptoms suggestive of side effects at all. The patients showed good adherence behavior on both the ARMS2 and VAS-AD scores, which were stable over time. The intensity of side effects experienced in the previous 7 days did not correlate with adherence scores and had no predictive value for adherence. Conclusion This study could not detect any significant influence of the subjectively experienced intensity of side effects on patients’ adherence behavior. However, we believe that a simple and clear treatment plan with few side effects is still preferred by most patients.

Abstract
BACKGROUND Poor adherence to therapy is a significant healthcare issue, particularly in patients with chronic disease such as open-angle glaucoma. Treatment failure may necessitate unwarranted changes of medications, increased healthcare expenditure and risk to the patient if surgical intervention is required. Simplifying eye drop regimes, providing adequate information, teaching drop instillation technique and ongoing support according to the patient need may have a positive effect on improving adherence. OBJECTIVES To summarise the effects of interventions for improving adherence to ocular hypotensive therapy in people with ocular hypertension (OHT) or glaucoma. SEARCH METHODS We searched CENTRAL (which contains the Cochrane Eyes and Vision Group Trials Register) (The Cochrane Library 2012, Issue 6), MEDLINE (June 1946 to June 2012), EMBASE (June 1980 to June 2012), Cumulative Index to Nursing and Allied Health Literature (CINAHL) (June 1937 to June 2012), PsycINFO (1806 to June 2012), PsycEXTRA (1908 to June 2012), Web of Science (1970 to June 2012), ZETOC (1993 to June 2012), OpenGrey (System for Information on Grey Literature in Europe) (www.opengrey.eu/), the metaRegister of Controlled Trials (mRCT) (www.controlled-trials.com), ClinicalTrials.gov (www.clinicaltrials.gov) and the WHO International Clinical Trials Registry Platform (ICTRP) (www.who.int/ictrp/search/en). We did not use any date or language restrictions in the electronic searches for trials. The electronic databases were last searched on 26 June 2012. We did not search the National Research Register (NNR) as this resource has now been now archived. We contacted pharmaceutical manufacturers to request unpublished data and searched conference proceedings for the Association for Research in Vision and Ophthalmology (ARVO), and the Annual Congress for the Royal College of Ophthalmologists (RCO). SELECTION CRITERIA We included randomised controlled trials (RCTs) and quasi-RCTs that compared interventions to improve adherence to ocular hypotensive therapy for patients with OHT or glaucoma. DATA COLLECTION AND ANALYSIS At least two authors independently assessed the search results for eligibility and extracted data for included trials onto specifically designed forms. We did not pool data due to clinical and methodological heterogeneity. MAIN RESULTS Sixteen trials (1565 participants) met the inclusion criteria. Seven studies investigated some form of patient education. In six of these studies this education was combined with other behavioural change interventions including tailoring daily routines to promote adherence to eye drops. Eight studies compared different drug regimens (one of these trials also compared open and masked monitoring) and one study investigated a reminder device. The studies were of variable quality and some were at considerable risk of bias; in general, the length of follow-up was short at less than six months with only two studies following up to 12 months. Different interventions and outcomes were reported and so it was not possible to produce an overall estimate of effect. There was some evidence from three studies that education combined with personalised interventions, that is, more complex interventions, improved adherence to ocular hypotensive therapy. There was less information on other outcomes such as persistence and intraocular pressure, and no information on visual field defects, quality of life and cost. There was weak evidence as to whether people on simpler drug regimens were more likely to adhere and persist with their ocular hypotensive therapy. A particular problem was the interpretation of cross-over studies, which in general were not reported correctly. One study investigated a reminder device and monitoring but the study was small and inconclusive. AUTHORS' CONCLUSIONS Although complex interventions consisting of patient education combined with personalised behavioural change interventions, including tailoring daily routines to promote adherence to eye drops, may improve adherence to glaucoma medication, overall there is insufficient evidence to recommend a particular intervention. The interventions varied between studies and none of the included studies reported on the cost of the intervention. Simplified drug regimens also could be of benefit but again the current published studies do not provide conclusive evidence. Future studies should follow up for at least one year, and could benefit from standardised outcomes.

Abstract
PURPOSE To develop a reliable and practical questionnaire for glaucoma awareness and evaluate the impact of potential determinants. METHODS Patients with primary open-angle, pigmentary, and exfoliation glaucoma, as well as healthy controls, were recruited. The instrument included questions about demographic characteristics, as well as 8 questions assessing the participant's familiarity with glaucoma. Rasch analysis was used for the validation of the questionnaire. The effect of demographics as potential determinants of awareness was examined with a multivariate logistic regression analysis. Bonferroni-corrected statistical significance was tested with the Mann-Whitney U test or one-way analysis of variance. Association between demographics and questionnaire scores was examined with Spearman correlation. RESULTS As indicated by power analysis, responses from 175 patients (mean age 65.5 years) and 314 controls (mean age 43.3 years) were analyzed. Rasch analysis indicated no multidimensionality and good item-person targeting. Mean ± SD awareness scores for the glaucoma and control groups were 4.43 ± 2.10 and 4.20 ± 2.11, respectively (p=0.207). Sex and residence were not predictors of disease awareness, whereas educational level was only a determinant in the control group (p<0.001). Income was a predictor only for patients (r=0.357, p<0.001), whereas family history was predictive for both groups (p<0.001). Logistic regression analysis revealed that only family history was associated with increased awareness (Chi(2)=4.61, p=0.03, odds ratio 1.98). CONCLUSIONS This study introduces a practical and valid instrument for the assessment of glaucoma awareness.

Abstract
Objective: To identify poorly compliant glaucoma patients, using the Eye-Drop Satisfaction Questionnaire (EDSQ). Methods: This was an observational cross-sectional study with compliance data collected by an electronic monitoring device. Patients with primary open-angle glaucoma or ocular hypertension completed the EDSQ, a six-dimension self-reported questionnaire addressing “treatment concern”, “disease concern”, “patient–clinician relationship”, “positive beliefs”, “treatment convenience”, and “self-declared compliance”. A Bayesian network (BN) was applied to explore compliance associations with EDSQ. Results: Among 169 patients who completed the EDSQ, 113 had valid Travalert® data, of whom 25 (22.1%) demonstrated low compliance. All six EDSQ dimensions were associated directly, or indirectly, with compliance. Two profiles exhibited low compliance, ie, patients aged younger than 77.5 years with a poor patient–physician relationship and self-declared poor compliance and patients aged older than 77.5 years with a poor patient–physician relationship and self-declared good compliance. The third profile showed high compliance, ie, patients aged younger than 77.5 years with a good patient-physician relationship and self-declared good compliance. Conclusion: Our results confirm a central role for the patient–physician relationship in the compliance process. Age, self-declared compliance, and patient satisfaction with the patient–physician relationship are all dimensions worth exploring before glaucoma medication is switched or proceeding to laser treatment or surgery.

Abstract
PURPOSE to establish the impact of educational support on patients' knowledge of glaucoma and adherence, in preparation for an intervention study. METHODS structured observation encapsulated the educational support provided during clinical consultations and patient interviews captured the depth of glaucoma knowledge, problems associated with glaucoma therapy, and adherence issues. RESULTS one hundred and thirty-eight patients completed the study. Education was didactic in nature, limited for many patients and inconsistent across clinics. Patients showed generally poor knowledge of glaucoma with a median score of 6 (range 0-16). A significant association was found between educational support and knowledge for newly prescribed patients (Kendall's tau=0.30, P=0.003), but no association was found for follow-up patients (Kendall's tau=0.11, P=0.174). Only five (6%) patients admitted to a doctor that they did not adhere to their drop regimen, yet 75 (94%) reported at interview that they missed drops. CONCLUSIONS although important, knowledge alone may not sufficiently improve adherence: a patient-centred approach based on ongoing support according to need may provide a more effective solution for this patient group.

Abstract
Glaucoma Primário de Ângulo Aberto (GPAA) é uma importante causa de cegueira no mundo. O presente trabalho teve como objetivo investigar: (1) presença e tipo de estresse; (2) relação do número de colírios e estresse; (3) percepção do glaucoma e tratamento. Um estudo transversal e quantitativo foi realizado com 102 pacientes do Ambulatório de Oftalmologia do HC-FMUSP, com roteiro temático e Inventário de Sintomas de Estresse de Lipp. A maioria dos pacientes apresentou estresse (65,7%) e não houve correlação entre estresse e número de colírios. "Tempo de tratamento", "dificuldades na vida diária" e "dificuldades em pingar o colírio" foram variáveis independentemente associadas ao estresse. Conclui-se que o estresse pode interferir negativamente no enfrentamento da doença em pacientes com GPAA.

Abstract
Background Individuals may need to be aware of glaucoma and seek assessment regularly in order to diagnose the condition early. Awareness of glaucoma has not been previously documented in an Ethiopian setting. Objective The main aim of this study was to assess the level of awareness of glaucoma among people attending outreach ophthalmic services. Methods We conducted a cross-sectional survey in April 2009 of all people 40 years of age or older who presented during a two-week outreach service period in Agaro town, southwestern Ethiopia. Data on demographics and awareness of glaucoma were collected through face to face interview using a pretested structured questionnaire. Results 340 people participated in the study. Their mean age was 54.5 (SD 10.6) years. About 43% were illiterates and 37.6% were farmers. Only eight people (2.4%) were aware of glaucoma. The association between awareness and attaining high school or better education was statistically significant (p < 0.0001). Conclusion Awareness of glaucoma in this population is very low. An efficient information, education and communication (IEC) strategy needs to be designed to increase knowledge of the community about glaucoma so that early diagnosis and treatment of individuals with this condition may be possible.

Abstract
Background Prior research has demonstrated that medication persistence (continued acquisition of therapy over time) is far from optimal among patients with glaucoma. The purpose of the present study was to evaluate persistence with prostaglandin analogs among glaucoma patients in the first therapy year using a modification of a previously published technique. Methods This retrospective analysis of medical and pharmacy claims database included treatment-naive patients dispensed bimatoprost, latanoprost, or travoprost between 1/1/04-12/31/04. "Index agent" was defined as the first agent filled; "index date" was defined as the fill date. Follow-up continued for 358 days. Persistence measures for first therapy year were: (1) whether last fill had sufficient days supply to achieve medication possession at year's end, and (2) number of days for which the index agent was available (days covered). Associations between index agent and medication possession (logistic regression) and days covered (linear regression) were evaluated. Models were adjusted for gender, age, and previous ocular hypertension diagnosis. Results 7873 patients met inclusion criteria (bimatoprost, n = 1464; latanoprost, n = 4994; travoprost, n = 1415). Medication possession was 28% and days covered was 131 when using the unadjusted (pharmacy-reported) days supply estimates and rose to 47-48% and days covered to 228-236 days when days supply was imputed. Compared to latanoprost, odds of achieving medication possession at first year's end were 26-34% lower for bimatoprost and 34-36% lower for travoprost (p ≤ 0.001 for all comparisons). Days covered in the first year were 21-29 days lower for bimatoprost and 33-42 days lower for travoprost (p ≤ 0.001 for all comparisons). Failure to refill the index agent within the initial 90 days was a strong predictor of poor persistence. Conclusions Persistence with ocular prostaglandin therapy remains a problem. Latanoprost users had greater odds of achieving medication possession and had more days covered during the first therapy year.

Abstract
OBJECTIVE To determine the rate of intentional and unintentional nonadherence in glaucoma patients and to identify associations between adherence behavior and patients' beliefs. DESIGN Cross-sectional study. PARTICIPANTS One hundred thirty-one glaucoma patients using topical eye drops for at least 6 months. METHODS Interviewer-administered surveys. MAIN OUTCOME MEASURES Self-reported adherence and beliefs about glaucoma and its treatment were assessed using the Reported Adherence to Medication scale, the Brief Illness Perception Questionnaire, and the Beliefs about Medicines-Specific Questionnaire. RESULTS Overall, 59 (45%) participants reported some degree of nonadherence, among whom 39 (66.1%) reported unintentional nonadherence (e.g., forgetting), 10 (16.9%) reported intentional nonadherence (deliberate nonadherence), and 10 (16.9%) reported both forms of nonadherence. Compared with adherers, nonadherers were significantly younger, were less likely to have other nonocular health conditions or to use medicines other than their eye drops, and reported lower belief in the necessity of eye drops for glaucoma (P<0.05). Degree of unintentional nonadherence was associated with lower belief in necessity of eye drops, whereas degree of intentional nonadherence was associated with concerns about eye drops. CONCLUSIONS Strategies aimed at improving adherence in glaucoma patients need to address both intentional and unintentional dimensions. Interventions focused on eliciting and addressing patients' beliefs and concerns about their eye drops require evaluation.

Scoring and psychometric properties of the Eye-Drop Satisfaction Questionnaire (EDSQ), an instrument to assess satisfaction and compliance with glaucoma treatment. BMC Ophthalmol 2010; 10:1.

Abstract
BACKGROUND The objective of this study was to ascertain the scoring and assess the psychometric properties of the Eye-Drop Satisfaction Questionnaire (EDSQ), a 43-item Patient-Reported Outcome instrument developed to assess patients' satisfaction and compliance with glaucoma treatment. METHODS The EDSQ was administered during an observational, retrospective study to 184 French patients treated for glaucoma. The hypothesized structure, including six dimensions (patient-clinician relationship; patient experience; patient-treatment interaction; apprehension; patient knowledge; travel), was tested by assessing the internal consistency reliability (Cronbach's alpha) and construct-related validity (item convergent and discriminant validity). As unsatisfactory results were demonstrated, another structure was defined using a principal component analysis (PCA) combined with content of items. Psychometric properties of this new structure were assessed. Scores were compared between low, moderate and high compliance profile groups defined using data collected with the Travalert electronic device. RESULTS Analyses were performed with the 169 patients who completed at least half of the EDSQ items. The hypothesized structure showed a Cronbach's alpha lower than 0.70 for four dimensions out of six and an overall poor construct-related validity (range of item-scale correlations: 0.00-0.68). The new structure obtained with the PCA included six dimensions: concern about treatment (five items); concern about disease (two items); satisfaction with patient-clinician relationship (five items); positive beliefs (three items); treatment convenience (three items); and self-declared compliance (three items). A score ranging from 0 to 100 was calculated for each dimension, with higher scores indicating more of the attribute referred to in the dimension. Internal consistency reliability was good (Cronbach's alpha greater than 0.70 for five dimensions). The structure offered good construct-related validity (range of item-scale correlations: 0.36-0.82). Ceiling effects of 21% and 49%, were observed for the satisfaction with patient-clinician relationship and self-declared compliance scores. Patients in low compliance profile group reported the lowest score for the satisfaction with patient-clinician relationship, positive beliefs, treatment convenience and self-declared compliance dimensions, and the highest score for the concern about treatment dimension. CONCLUSIONS The scoring of the EDSQ was developed and the questionnaire proved to have satisfactory psychometric properties. EDSQ scores showed a promising relationship to compliance profiles. The EDSQ could be used in future studies.

Abstract
Glaucoma is defined as an optic neuropathy, characterized for loss of visual field and injury of the optic nerve, being considered as the second cause of blindness in the world, which could be prevented by the use of antiglaucoma eyedrops. The lack of adhesion of the patient to the drug treatment can culminate with loss of the vision. The objective was to revise possible literature data regarding intervening factors for noncompliance and explain estimated rates of noncompliance. A systematic review about the subject was carried out in the period of January to June of 2006. Articles had been searched in two data bases, in the National Library of Medicine (PUBMED) and in the Literature Latin American and Caribbean Health Sciences (LILACS) using the following keywords: glaucoma, compliance of the patient, noncompliance of the patient, treatment and eyedrops. In PUBMED, 199 articles were collected, written in English and French languages. No article was found in LILACS. Considering the inclusion and exclusion criteria, 27 articles were selected, with 25 originals and two reviews. Twelve possible intervening factors for noncompliance were raised, as well as estimates for rates of noncompliance. The noncompliance rates varied from 4.6% up to 59%. Two factors, forgetfulness and inadequate between-doses interval, had been associated to noncompliance of the drug therapy. The factors race, adverse effects, treatment cost, number of instilled doses, coexisting illnesses and number of eyedrops used, had resulted contradictory, being impossible to affirm that they have contributed for noncompliance. Age, sex, educational level and loss of visual field, had not been associated with noncompliance. The glaucoma patients tended to disregard the drug treatment. The wide variation in noncompliance rates could be an influence from the authors' difficulty to define the noncompliance and the variety of methodologies used to estimate it. More studies are necessary for a better evaluation of these 12 raised factors.

Abstract
PURPOSE Estimate patient adherence to glaucoma medications and identify potential determinants of nonadherence. DESIGN Descriptive study. METHODS Two hundred patients with open angle glaucoma, ocular hypertension, or glaucoma suspects were interviewed regarding their glaucoma and its treatment and their charts were reviewed. Their ophthalmologist completed a brief assessment form. Drug utilization data were extracted from the provincial drug program database. Patients were defined as adherent if they filled at least 75% of the prescribed medication necessary for their treatment. RESULTS Data were available for 181 patients. About 62.9% were female and the mean age (+/-SD) was 75.1+/-8.8 years. The mean number of years of glaucoma treatment was 10.7+/-9.3. Self-reported treatment adherence was 88.3%. On the basis of the drug database, the proportion of patients who were adherent to treatment was 71.8%. According to physicians, 74.6% of patients were adherent. Among patients considered by physicians as nonadherent, 71.1% (32/45) were adherent and among patients predicted as adherent, 72.1% (98/136) were adherent. There was no significant difference in adherence according to age, sex, education, and income. However, patients using fewer agents (P=0.041), who were widowed (P=0.041), or who lived alone (P=0.042) were more adherent. Patients using prostaglandins analogs or beta-blockers were more adherent than those using carbonic anhydrase inhibitors (P<0.05). CONCLUSIONS Fewer medications, use of prostaglandin analogs or beta-blockers, living alone, and being widowed were significantly associated with adherence. Physicians were unable to significantly predict which patients are adherent.

Abstract
BACKGROUND Poor adherence to therapy is a significant healthcare issue, particularly in patients with chronic disease such as open angle glaucoma. Treatment failure may necessitate unwarranted changes of medications, increased healthcare expenditure and risk to the patient if surgical intervention is required. Simplifying eye drop regimes, providing adequate information and ongoing support according to patient need, may have a positive effect on improving adherence. OBJECTIVES To summarise the effects of interventions for improving adherence to ocular hypotensive therapy in people with ocular hypertension (OHT) or glaucoma. SEARCH STRATEGY We searched CENTRAL, MEDLINE, EMBASE, CINAHL, PsycINFO, Web of Science, ZETOC and OpenSIGLE. In addition, we searched research registers of ongoing studies. We contacted pharmaceutical manufacturers to request unpublished data and searched conference proceedings for the Association for Research in Vision and Ophthalmology (ARVO), and the Annual Congress for the Royal College of Ophthalmologists (RCO). There were no language or date restrictions in the search for trials. The electronic databases were last searched on 15 January 2009. SELECTION CRITERIA We included randomised controlled trials (RCTs) and quasi RCTs that compared interventions to improve adherence to ocular hypotensive therapy for patients with OHT or glaucoma. DATA COLLECTION AND ANALYSIS At least two authors independently assessed the search results for eligibility and extracted data for included trials onto specifically designed forms. We calculated the mean difference for continuous data and relative risks for dichotomous data. Where appropriate, we pooled data using a fixed-effect model. MAIN RESULTS Eight trials met the inclusion criteria. There was considerable heterogeneity of interventions and reported outcome measures and therefore, meta-analysis was limited to two studies. Overall, studies were not of high quality due to small sample sizes, missing data and short term follow-up. Three of five drug comparison studies provided evidence that reducing the frequency of drops can improve adherence. However, the study that compared the least frequent regime with one of the most complicated, showed no difference in reported adherence. A small study of thirteen patients found a reminder device beneficial to adherence levels yet only one of two studies involving education and individualised care planning was found to be successful. AUTHORS' CONCLUSIONS Interventions involving simplified dosing regimes, reminder devices, education and individualised care planning, did show improvements in adherence rates. However, due to inadequate methodological quality and heterogeneity of study design we are unable to advocate any particular interventions at this time.

Abstract
Adherence and persistence with chronic therapies is crucial to prevent disease progression, such as in glaucoma. Patients report high rates of adherence, which are not supported by pharmacy claims analysis. This article reviews the literature regarding methods to assess adherence and persistence and the patient behaviors that pose challenges to proper treatment. Rates for persistence are generally below 50% at 1 year. Differentiating efficacy of eyedrops from lack of adherence presently confounds ophthalmic treatment. Additionally, as intraocular pressure (IOP) can appear controlled by short-term adherence, the physician can be fooled into believing the patient's glaucoma is well-controlled. Likewise, when progressive worsening is noted despite good IOP control, it can be problematic whether the patient's target pressure needs to be lowered or adherence needs to be improved. White-coat adherence is common, in which patient adherence rises sharply 1 week before the appointment with the physician, then declines rapidly following the appointment. White-coat adherence may make it difficult to assess IOP control over the longer term; cycling behavior with medication use is well-documented. Adherence and persistence rates differ by class of drug, with higher rates associated with prostaglandin use. We review findings from The Glaucoma Adherence and Persistency Study that identified behaviors associated with poor adherence. Greater physician awareness of adherence and persistence issues is necessary in order to help the patient become more adherent.

Abstract
PURPOSE To identify specific items on knowledge and need for information that could be used to improve compliance with glaucoma medication. METHODS Forty-four randomly selected ophthalmologists assigned 166 consecutive glaucoma patients to complete a questionnaire. The questionnaire was developed systematically based on focus group interviews, consultation of experts and a pilot test. Items included knowledge about glaucoma and its treatment, need for information and compliance with therapy. RESULTS No statistically significant correlation was found between the total level of knowledge and compliance. Concerning knowledge of glaucoma, one out of 19 items had a statistically significant negative correlation with compliance. Concerning knowledge of glaucoma treatment, one out of 18 items had a statistically significant positive correlation with compliance. Regarding total need for information, no statistically significant correlation with compliance was found. Three out of 22 items had a statistically significant positive correlation with compliance. CONCLUSION Given the number of related items, their direction and limited strength of correlation and the difficulty of hypothesizing a causal relation for some items, it is unlikely that further improving knowledge will greatly improve compliance with glaucoma medication. Interventions focused on attitude and discipline may be of more benefit in improving compliance with therapy.

Abstract
BACKGROUND To assess the prevalence and determinants of non-adherence to topical hypotensive treatment in glaucoma patients in order to support interventions targeting enhancement of patient adherence. METHODS One-hundred and sixty-six glaucoma patients, recruited by nationwide multi-stage sampling, filled in an extensive and carefully developed questionnaire covering various theoretically relevant determinants of patient adherence which were categorized as psychosocial aspects, barriers and skills. RESULTS Prevalence of self-reported non-adherence was 27.3%. Younger patients (<55 years of age) had a higher risk of being non-adherent. Forgetfulness, unavailability of eye drops and difficulties with holding the bottle above the eye when applying the eye drops were the most cited reasons for non-adherence. Fifty percent of the patients indicated that they required more information on the correct administration of eye drops. There was no association between non-adherence and sex, level of education, type of insurance, duration of disease or family history of glaucoma. CONCLUSIONS Non-adherence to topical glaucoma medication is fairly common. Aids that minimize forgetfulness and delivery systems facilitating the delivery of medications to the eye could be considered to enhance patient adherence before advancing to other therapies with additional risks and costs.

Abstract
Glaucoma is a leading cause of blindness worldwide. Currently, topical drops are the mainstay of treatment for patients who suffer from this chronic disease. Adherence to topical therapy is known to be affected by forgetfulness, frequent dosing requirements and physical limitations. Dosing and adherence aids are designed to help patients adhere to their prescribed therapeutic regimens. This review discusses commonly used dosing and adherence aids, and offers opinions on how future devices may improve on currently available technology.

Abstract
This study was undertaken to evaluate the efficiency of a trabecular micro-bypass stent designed to allow direct aqueous drainage from the anterior chamber into Schlemm's canal in patients with glaucoma. In this prospective case series of 6 patients with open-angle glaucoma, the microstent was inserted ab interno under local anesthesia in an ophthalmic operating room. Patients were seen postoperatively at 1 to 2 d, 1 wk, and 1, 2, 6, and 12 mo. All stents were successfully placed within Schlemm's canal. Mean intraocular pressure (IOP) at preoperative baseline was 20.2+/-6.3 mm Hg (range, 14-31 mm Hg). Mean IOP decreased during the immediate postoperative period to approximately 12 to 13 mm Hg and was stabilized at 14 to 15 mm Hg with reduction of medication throughout 1 y of follow-up. No major complications occurred. According to observations reported in this feasibility study, the microstent was effective in reducing IOP and in decreasing the number of glaucoma medications required to control IOP. Implantation procedures were safe, and stents remained in place throughout the follow-up period. None of the complications traditionally associated with filtering surgery were reported. Further research on this stent in a larger group of patients is needed to assess its role in glaucoma therapy.

Abstract
OBJECTIVE The aim of this study was to assess the impact of psychological distress and personality traits on self-rated compliance with glaucoma treatment. METHODS One hundred patients with primary open-angle glaucoma participated in the study. General Health Questionnaire, Symptom Distress Checklist, Center for Epidemiological Studies Depression Scale, Defense Style Questionnaire, and Hostility and Direction of Hostility Questionnaire were used. RESULTS Forty-two percent of patients with glaucoma classified as "noncompliers," those who omitted more than two doses per week. Noncompliers presented more severe symptoms of glaucoma. Depression was found to be associated with poor compliance, whereas adoption of immature defensive style further increased the risk for noncompliance with glaucoma treatment. CONCLUSIONS Depression is associated with self-reported noncompliance with glaucoma treatment, whereas certain personality traits are involved in the increased risk for noncompliance. Further assessment of the depressive feelings by an ophthalmologist and treatment of depression as well as proper psychotherapeutic approaches for maladaptive personality features could be an essential strategy to diminish compliance problems.

Abstract
A constantly aging population leads to an increasing number of elderly patients. As a result, the treatment of chronic illnesses becomes a significant part of daily routine. Today's concepts in social services and healthcare require time consuming and barely cost-effective efforts for the special needs of geriatric care. The use of telemedicine offers a possible solution, because telemedical methods may help to realize improved monitoring systems for optimized and effective patient management. This report provides an overview of the scenarios and advantages of telemedicine in general. In addition, we provide information on practical experiences in a project on telemedical glaucoma management in Mecklenburg-Vorpommern.

Abstract
AIM To evaluate the recently introduced Travatan Dosing Aid (TDA) for its accuracy in recording and dispensing eyedrops. METHODS The number of eyedrops dispensed with each lever depression and agreement of total number of drops dispensed with that recorded by the device was evaluated in a controlled setting. RESULTS The TDA correctly recorded a drop being dispensed 100% of the time with full TDA lever depression for <3 s. Under these conditions, agreement between numbers of drops dispensed and recorded was 99%. However, failure to fully depress the lever or prolonged lever depression for >4 s resulted in unreliable TDA recording. CONCLUSION Eyedrops were reliably recorded by the TDA after each full lever depression. However, patients need to be instructed about optimal technique so that evaluation of compliance is not confounded by mechanical factors.

Abstract
PURPOSE 1) To summarize the literature on compliance (the extent to which the patient's behaviors correspond with the provider's recommendations) and persistence (total time on therapy) in patients with open-angle glaucoma or ocular hypertension. 2) To suggest guidelines to improve these two parameters, which are both essential and integral elements of optimizing patient care. METHODS Compliance-related research published between 1980 and March 2005. RESULTS Medication compliance has mostly been investigated and measured using patient self-reports, electronic monitoring, and medication possession ratio. Noncompliance-related problems are underestimated, complex, unpredictable and frequent. Noncompliance rates of at least 25% have been reported. The main obstacles to medication compliance are situational/environmental or related to the side effects or complexity of the medication regimen. Persistence with glaucoma medications has also been proven to be poor. Based on retrospective studies using survival analyses, fewer than 25% of patients may be persistent over 12 months. Persistence rates differ from one treatment to another and may fluctuate with time in the same patient. CONCLUSIONS Improving the quality of information, the patient-physician relationship, and educating patients are all crucial. Simplification of the treatment regimen and selection of medications with the fewest systemic and ocular side effects must be a priority. Accurately assessing patient compliance and persistence are indispensable to reducing mistakes from either medication noncompliance or lack of persistence with poor efficacy and to avoid unnecessary changes in a patient's therapeutic regimen or surgery.

Abstract
BACKGROUND Although interaction between doctor and patient is undoubtedly influenced by their mutual expectations, little information is available about the knowledge and expectations of glaucoma doctors concerning their patients' attitudes and treatment patterns. The aim of our prospective study was to compare the actual responses of glaucoma patients concerning various issues related to their disease and the responses the glaucoma doctors expected their patients to give. METHODS Glaucoma patients consecutively sent to our glaucoma centre were asked to complete a standardised questionnaire about their glaucoma history, treatment routines and opinions on issues related to glaucoma. Ophthalmologists at the glaucoma centre were asked to predict patients' answers. RESULTS One hundred and twenty-eight consecutive glaucoma patients completed the patients' questionnaire and 12 glaucoma specialists completed the corresponding questionnaire for doctors. Frequency of intraocular pressure (IOP) measurements and visual field testing, as well as the number of topical medications, were relatively accurately predicted by the glaucoma doctors. Differences between the doctors' predictions and patients' responses were found concerning discomfort after surgery and the influence of stress or environmental factors on IOP. The largest range of doctors' predictions (0-100%) was observed concerning the portion of patients claiming a 100% adherence to glaucoma medication. CONCLUSION Glaucoma specialists are familiar with the treatment patterns of their patients. The knowledge of glaucoma specialists of their patients' subjective attitudes to glaucoma-related issues deserves further investigation, as discrepancies between doctors' and patients' responses were observed in this area.

Abstract
BACKGROUND In order to look for conceptual improvements in the practical management of patients sent to our glaucoma department, we analyzed the structures, behaviour, and knowledge about the disease in this patient group. METHODS Glaucoma patients who were sent for the first time to our department were included prospectively. Before being examined 129 patients were asked to answer a questionnaire concerning their individual characteristics, their behaviour, and patterns of treatment. RESULTS Of the patients 74% had open-angle glaucoma (including normal tension, exfoliative, and pigment glaucoma), 22% had secondary glaucoma (including neovascular, congenital, and chronic closed-angle glaucoma), and 4% had suspected glaucoma. Written documentation of previously performed intraocular pressure measurements was not available for 84% of the patients. Younger patients had significantly more knowledge about glaucoma and used more possibilities to get information about the disease than elder patients. CONCLUSION Education about glaucoma disease should be optimized especially for elder glaucoma patients. Documentation of intraocular pressure measurements is insufficient in our patient group.
