Meliante LA, Piccotti G, Tanga L, Giammaria S, Manni G, Coco G. Glaucoma, Pseudoexfoliation and Hearing Loss: A Systematic Literature Review. J Clin Med 2024; 13:1379. [PMID: 38592217 PMCID: PMC10931971 DOI: 10.3390/jcm13051379] [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: 12/29/2023] [Revised: 02/18/2024] [Accepted: 02/23/2024] [Indexed: 04/10/2024] Open
Abstract
Purpose: To investigate the relationship between glaucoma, pseudoexfoliation and hearing loss (HL). Methods: A systematic literature search following PRISMA guidelines was conducted using the PubMed, Embase, Scopus and Cochrane databases from 1995 up to 28 August 2023. Results: Thirty studies out of the 520 records screened met the inclusion criteria and were included. Most articles (n = 20) analysed the association between pseudoexfoliation syndrome (XFS) and HL, showing XFS patients to have higher prevalence of sensorineural hearing loss (SNHL) at both speech frequencies (0.25, 0.5, 1 and 2 kHz), and higher frequencies (4 and 8 kHz) compared to controls in most cases. No significant differences in prevalence or level of HL between XFS and pseudoexfoliative glaucoma (XFG) were detected in most studies. Eight articles analysed the relationship between primary open-angle glaucoma (POAG) and HL. Overall, a positive association between the two conditions was highlighted across all studies except for two cases. Similarly, articles focusing on NTG and HL (n = 4) showed a positive association in most cases. The role of autoimmunity and, in particular, the presence of antiphosphatidylserine antibodies (APSA) in patients with NTG and HL suggested an underlying autoimmune or vascular mechanism contributing to their pathogenesis. Only one study analysed the relationship between angle-closure glaucoma (ACG) and HL, showing higher incidence of ACG in patients with SNHL compared to normal hearing controls. Conclusions: Most studies detected an association between XFS and HL as well as POAG/NTG/ACG and HL, suggesting the presence of a similar pathophysiology of neurodegeneration. However, given the strength of the association of XFS with HL, it remains unclear whether the presence of XFG is further associated with SNHL. Further research specifically targeted to assess the correlation between glaucoma, XFS and HL is warranted to provide a more comprehensive understanding of this association.

Abstract
OBJECTIVES To investigate the bidirectional association between sudden sensorineural hearing loss (SSNHL) and open-angle glaucoma (OAG) over a 12-year follow-up period using nationwide, population-based data. METHODS The study was conducted using the National Health Information Database of the National Health Insurance Service (NHIS-NHID), which covered 3.5 million individuals from 2008 to 2019. In Study 1, we evaluated the effect of OAG on SSNHL, and in Study 2, we evaluated the effect of SSNHL on OAG. Participants of the control group were enrolled through "greedy nearest-neighbor" 1:1 propensity score matching. RESULTS In Study 1, 26,777 people were included in each group. The hazard ratio (HR) for SSNHL of the OAG group was 1.27 (95% confidence interval [CI], 1.15-1.39). In subgroup analysis, there was significant HR value regarding (old age: 1.17, hyperlipidemia: 1.19). In Study 2, 15,433 people were included in each group. The HR for OAG of the SSNHL group was 1.18 (95% CI, 1.07-1.30). In subgroup analysis, the HRs were significant for old age (2.31), hypertension (1.17), diabetes (1.39), and hyperlipidemia (1.26). CONCLUSION Over the 12-year follow-up, we found a bidirectional association between SSNHL and OAG, suggesting a shared pathogenesis. LEVEL OF EVIDENCE N/A. Laryngoscope, 133:3169-3177, 2023.

Na KI, Lee WJ, Kim YK. Trends in the Prevalence of Blindness and Correlation With Health Status in Korean Adults: A 10-Year Nationwide Population-Based Study. J Korean Med Sci 2023; 38:e213. [PMID: 37463686 DOI: 10.3346/jkms.2023.38.e213] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/16/2022] [Accepted: 03/22/2023] [Indexed: 07/20/2023] Open
Abstract
BACKGROUND Contemporary data on vision impairment form an important basis for public health policies. However, most data on the clinical epidemiology of blindness are limited by small sample sizes and focused not on systemic conditions but ophthalmic diseases only. In this study, we examined the ten-year trends of blindness prevalence and its correlation with systemic health status in Korean adults. METHODS This study investigated 10,000,000 participants randomly extracted from the entire Korean population (aged ≥ 20 years) who underwent a National Health Insurance Service health checkup between 2009 and 2018. Participants with blindness, defined as visual acuity in the better-seeing eye of ≤ 20/200, were identified. The prevalence of blindness was assessed, and the systemic health status was compared between participants with blindness and without blindness. RESULTS The mean prevalence of blindness was 0.473% (47,115 blindness cases) and tended to decrease over ten years (0.586% in 2009 and 0.348% in 2018; P < 0.001). The following factors were significantly associated with blindness: female sex, underweight (body mass index < 18.5), high serum creatinine (> 1.5 mg/dL), and bilateral hearing loss. In addition, except for those aged 30-39 and 40-49 years, high fasting glucose (≥ 126 mg/dL) and low hemoglobin (male: < 12 g/dL, female: < 10 g/dL) were significantly correlated with prevalent blindness. CONCLUSION Our ten-year Korean nationwide population-based study suggested a gradual decrease in the prevalence of blindness and its association with specific systemic health status. These conditions might be the cause or consequence of blindness and can be used as a reference for the prevention and/or rehabilitation of blindness to establish public health policies.

Abstract
OBJECTIVE To determine if exfoliation syndrome (XFS) is associated with hearing loss (HL) or vestibular dysfunction. DATA SOURCES PubMed, Scopus, CINAHL, and Cochrane Library through April 1, 2022. REVIEW METHODS Two reviewers independently screened abstracts, selected articles for inclusion, and extracted data. Studies included for qualitative analysis conducted audiometric, tympanometric, or vestibular evaluations on all subjects. RESULTS Twenty-one publications (1148 patients with XFS and 1212 controls) were included in the systematic review, and 16 publications (968 patients with XFS and 1147 controls) in the meta-analysis. Greater severity of HL was seen for patients with XFS compared to controls across all frequencies (odds ratio [OR] 8.8 [7.3-10.2]). Patients with XFS were more likely to have moderate to profound sensorineural HL (OR 1.8 [1.3-2.5]), and less likely to have none to mild HL (OR 0.34 [0.17-0.67]) or no HL (OR 0.37 [0.28-0.50]). Three studies found patients with XFS had lower tympanometric peaks. Two studies found that abnormal vestibular testing results could be more common for patients with XFS. CONCLUSIONS HL is associated with XFS. A sensorineural component to HL is confirmed, and mixed HL is possible. Given the high prevalence and infrequent diagnosis of XFS, the authors hypothesize that the current understandings of presbycusis might be improved by further investigation in XFS.

Abstract
Objectives Patients with pseudoexfoliation syndrome (PES) can also have sensorineural hearing loss as well as balance problems. Our aim was to evaluate vestibulocochlear system involvement in PES patients. Materials and Methods The study included 16 subjects with PES (study group) with a mean age of 66.12±5.64 years and 17 healthy subjects (control group) with a mean age of 61.70±8.46 years. Both groups underwent ophthalmological, neuro-otological, audiological, and vestibular evaluation. Pure-tone audiometry and tympanometry were performed as audiological tests and bithermal caloric test and vestibular-evoked myogenic potential (VEMP) testing were used as vestibular tests. The Romberg, tandem Romberg, and Unterberger tests were also performed. Results In the PES group, bithermal caloric tests revealed right canal paresis in 6 patients, left canal paresis in 3 patients, and bilateral stimulation loss in 2 patients, despite no clinical evidence of balance loss. Paresis was not detected in any of the control subjects. Unilateral VEMP responses could not be obtained in 3 patients in the PES group. The ocular PES patients whose VEMP waves were obtained differed significantly from the control group (p<0.05). In office tests for vestibular evaluation, pathologic findings were found in 7 of 16 patients in the study group and only 4 subjects in the control group. Audiological evaluation with pure-tone thresholds revealed sensorineural decline at 4000 and 8000 Hertz in the PES patients. A statistically significant difference was found between the study group and the control group (p<0.05). Conclusion Patients with PES showed elevation in pure-tone thresholds and a decrease in superior and inferior vestibular nerve function, demonstrating that the vestibular system as well as the auditory system are affected in PES.

Abstract
PURPOSE To evaluate nasal mucociliary clearance (NMC) and hearing loss in patients with pseudoexfoliation (PEX) syndrome. METHODS The study included 36 patients with PEX syndrome as the study group, and 39 healthy individuals as the control group. The duration of NMC was measured using the saccharine test. Audiometry was applied at 250, 500, 1000, 2000, 4000, 6000 and 8000 Hz frequencies to determine hearing thresholds and prevalence of hearing loss. RESULTS No statistically significant difference was determined between the groups in respect of age and gender (p = 0.23 and p = 0.36, respectively). In the saccharine test, the mean NMC time was 18.41 ± 8.53 min for the study group and 11.69 ± 4.96 min for the control group. The mean NMC time of study group was significantly longer than that of the controls (p < 0.001). In the comparisons of the two groups in terms of the prevalence of hearing loss, no statistically significant difference was found at any of the evaluated frequencies (p > 0.05, for all). There was also no statically significant difference between groups in relation to hearing thresholds at these frequencies (p > 0.05, for all). CONCLUSION The NMC time was significantly prolonged in patients with PEX syndrome. This result indicates that nasal mucosa cilia, which have similar elastic and mobile structures as the iris, are damaged in PEX syndrome, which is an infiltrative disease increasing the rigidity of affected tissues. In upper respiratory tract infections of unknown cause, PEX syndrome should be considered among the etiological factors. In this study, no significant relationship was detected between PEX and hearing loss.

Abstract
PURPOSE This study identifies the prevalence and risk factors of sensorineural hearing loss and primary open-angle glaucoma (POAG). MATERIALS AND METHODS Patients aged 19 years or older who had undergone both ophthalmologic examination and audiometry as part of the Korea National Health and Nutrition Examination Survey V (2010-2012) were analyzed. Hearing loss was defined as the pure-tone average over 40 decibels based on the automatic hearing test to determine the threshold of airway hearing for each frequency. We investigated the prevalence of glaucoma and hearing loss when they occurred alone or simultaneously. The risk factors for concurrent glaucoma and hearing loss were examined. RESULT Among the participants, 6.6% had hearing loss alone, 2.3% had glaucoma alone, and 0.5% had both glaucoma and hearing loss. The weighted prevalence of glaucoma in patients with hearing loss was 7.5%; however, the weighted prevalence of glaucoma was 3.2% among patients without hearing loss, with a significant difference (P < .001). Multivariable logistic regression analysis revealed that the risk factors associated with concurrent glaucoma and hearing loss were age (3.786 times per 10 years, P < .001) and triglyceride level (1.002 times per 1 mg/dL, P = .028). CONCLUSION Sensorineural hearing loss and POAG are relevant. If hearing impairment and visual impairment occur together, the quality of life of the patient is worsened and the social burden is greater. Therefore, care should be taken when treating elderly patients with glaucoma.

Abstract
This study was conducted using the database of the Korea National Health and Nutrition Examination Survey to determine whether age-related eye diseases such as cataract, glaucoma, diabetic retinopathy (DR), and age-related macular degeneration (AMD), are related to hearing loss. 12,899 participants ≥ 40 years of age were included. The weighted prevalence of diabetic retinopathy was not significantly different between the normal hearing group and hearing-impaired group, but the weighted prevalences of cataract, glaucoma, early AMD, and late AMD were significantly different in the two groups. The odds ratio for cataract in the hearing-impaired group was 1.373 (1.118–1.687). The odds ratios of glaucoma, DR, early AMD, and late AMD were not significantly different in the hearing-impaired group. Age was significantly associated with the presence of concurrent cataract and hearing impairment by 6.574-fold per decade. Significant factors that increased the risk of concurrent glaucoma and hearing impairment were age, male gender, and triglyceride. Age, ex-smoker, systolic BP elevation, BMI decline, and fasting blood sugar significantly predicted the presence of concurrent DR and hearing loss. In early AMD, age and triglyceride, and in late AMD, age and systolic BP elevations increased the risk of concurrent AMD and hearing impairment.

Abstract
PURPOSE To summarize various topics and the cutting edge approaches to refine XFS pathogenesis that were discussed at the 21st annual Glaucoma Foundation Think Tank meeting in New York City, Sept. 19-20, 2014. METHODS The highlights of three categories of talks on cutting edge research in the field were summarized. RESULTS Exfoliation syndrome (XFS) is a systemic disorder with a substantial ocular burden, including high rates of cataract, cataract surgery complications, glaucoma and retinal vein occlusion. New information about XFS is akin to puzzle pieces that do not quite join together to reveal a clear picture regarding how exfoliation material (XFM) forms. CONCLUSION Meeting participants concluded that it is unclear how the mild homocysteinemia seen in XFS might contribute to the disarrayed extracellular aggregates characteristic of this syndrome. Lysyl oxidase-like 1 (LOXL1) variants are unequivocally genetic risk factors for XFS but exactly how these variants contribute to the assembly of exfoliation material (XFM) remains unclear. Variants in a new genomic region, CACNA1A associated with XFS, may alter calcium concentrations at the cell surface and facilitate XFM formation but much more work is needed before we can place this new finding in proper context. It is hoped that various animal model and ex vivo systems will emerge that will allow for proper assembly of the puzzle pieces into a coherent picture of XFS pathogenesis. A clear understanding of XFS pathogenesis may lead to 'upstream solutions' to reduce the ocular morbidity produced by XFS.

Abstract
PURPOSE To determine whether adults, aged 66-96 years, with exfoliation syndrome (XFS)/exfoliation glaucoma (XFG), or primary open-angle glaucoma (POAG) have poorer hearing than controls of similar age. METHODS Case (XFS/XFG and POAG) and control status was diagnosed in the Reykjavik Glaucoma Studies (RGS) using slit-lamp examination, visual field testing and optic disc photographs; the RGS data were merged with the Age, Gene/Environment Susceptibility-Reykjavik Study that collected hearing data using air-conduction, pure-tone thresholds obtained at 0.5, 1, 2, 3, 4, 6 and 8 kHz categorized by better ear and worse ear, based on pure-tone averages (PTAs) calculated separately for low and middle frequencies (PTA512 - mean of thresholds at 0.5, 1 and 2 kHz) and high frequencies (PTA3468 - mean of thresholds at 3, 4, 6 and 8 kHz). Multivariable linear regression was used to test for differences in PTAs between cases and controls. RESULTS The mean age for 158 XFS/XFG cases (30.4% male) was 77.4 years, 95 POAG cases (35.8% male) was 77.9 years, and 123 controls (46.3% male) was 76.8 years. Using multivariable linear regression analysis, there were no consistent, statistically significant differences in PTAs between the two case groups and controls in either the low- or high-frequency range, even when stratified by age group. CONCLUSION Among the older individuals examined in this study hearing loss is highly prevalent and strongly associated with male gender and increasing age. As we did not find consistent statistically significant difference in hearing between cases and controls the diagnosis of XFS/XFG or POAG does not as such routinely call for audiological evaluation.

Abstract
Exfoliation syndrome (XFS) is an age-related disease characterized by the production, deposition, and progressive accumulation of a white, fibrillar, extracellular material in many ocular tissues, most prominent on the anterior lens surface and pupillary border. Its prevalence increases steadily with age in all populations. It is the most common identifiable cause of open-angle glaucoma worldwide and is a potentially reversible or even curable disease. First described in Finland in 1917 by Lindberg, it has long been associated with open-angle glaucoma. However, in recent years, it is being increasingly reported in conjunction with a multiplicity of both ocular and systemic disorders, and the number of these is expected to grow, particularly with investigations based on attempts to associate other diseases with those genes known to be associated with XFS. Despite the focus on XFS as a cause of open-angle glaucoma for nearly a century, in reality it is still only an ocular manifestation of a protean systemic disease. It is a unique disorder with extensive and often serious ocular and systemic manifestations and not, as it has long been termed, a "form" or "type" of glaucoma. This misconception has delayed research into the molecular and cellular processes involved in its development, and the underestimation of its overall importance and its underlying causative mechanisms have largely been long ignored. The purpose of this article is to review the systemic disorders which are becoming increasingly associated with XFS. Reviews of epidemiology, genetics, biomarkers, molecular mechanisms of development, and ocular findings may be found elsewhere.

Abstract
Objective. The aim of this prospective study was to audiologically evaluate consecutive glaucoma patients with or without exfoliation. Study Design. Prospective study. Setting. Glaucoma Unit and Audiology Department at a university hospital. Subjects and Methods. Consecutive subjects with exfoliative glaucoma (XFG) or primary open-angle glaucoma (POAG) aged between 50 and 70 years were enrolled. Auditory thresholds at 0.5, 1.0, 2.0, 4.0, and 8.0 Hz were measured bilaterally. Cochlear activity was assessed by recording distortion product otoacoustic emissions (DPOEs). Functional changes in the retrocochlear auditory pathway were evaluated by auditory brainstem responses (ABRs). Results. One hundred and ten patients with XFG and 85 patients with POAG who presented in a glaucoma clinic were investigated. The mean age of study patients was 66.2 ± 5.6 years; range, 50-70 years). The odds of pathologic ABR central transmission time (interpeak latencies I-III, III-V, and I-V and waves I, III, and V) were 4.34 times higher in patients with XFG than in patients with POAG (95% confidence interval [CI], 2.22-8.49; P < .001). This significant association remained after adjusting for sex and age (odds ratio [OR] 4.12; 95% CI, 2.07-8.22; P < .001). Furthermore, the odds of ABR remained significantly higher in patients with XFG than in patients with POAG (OR 4.36; 95% CI, 2.10-9.06; P < .001) after controlling for systemic diseases (arterial hypertension, coronary heart disease, high cholesterol, and stroke). Conclusion. In the first study to compare XFG and POAG monitoring of the peripheral and central auditory pathway, it has been documented that XFG patients show a greater prevalence of retrocochlear pathology.
