Inhaled Corticosteroid and Secondary Glaucoma: A Meta-analysis of 18 Studies

Glucocorticoid-Induced Ocular Hypertension and Glaucoma

Glucocorticoid (GC) therapy is indicated in many diseases, including ocular diseases. An important side-effect of GC therapy is GC-induced ocular hypertension (GIOHT), which may cause irreversible blindness known as GC-induced glaucoma (GIG). Here, we reviewed the pathological changes that contribute to GIOHT including in the trabecular meshwork and Schlemm's canal at cellular and molecular levels. We also discussed the clinical aspects of GIOHT/GIG including disease prevalence, risk factors, the type of GCs, the route of GC administration, and management strategies.

Ocular Surface, Intraocular Pressure and Lens Condition in Bronchodilator and Steroid-Treated Patients with Chronic Pulmonary Disease

OBJECTIVES

The aim of this study was to investigate ocular surface, intraocular pressure and lens condition in bronchodilator- and steroid-treated chronic pulmonary disease patients.

METHODS

In this cross-sectional clinical study, 101 patients with chronic pulmonary disease were treated with an inhaler and/or nebulized therapy for bronchodilatation. The patients were evaluated in 2 groups namely chronic obstructive pulmonary disease (COPD) and asthma. We investigated the effects of patient demographic characteristics, smoking, and medications on the presence of dry eye disease (DED), intraocular pressure, and cataract.

RESULTS

Patients had a mean age of 66.4 ± 11.9 years, and 46.5% (n = 47) were female. A unit increase in the length of inhaled corticosteroids (ICS) and long-acting beta-agonists (LABA) combination use was associated with a 1.02-fold increase in cataract risk (OR: 1.02, CI: 1.01-1.04, p = 0.016), and current smokers had 10.8 times as many cataracts (OR: 10.79, CI: 1.70-68.30, p = 0.011). Patients who used a nebulized corticosteroid had a 9.15 times higher risk of developing dry eyes than those who did not (OR: 9.15, CI: 2.34-35.75, p = 0.001). In patients using ICS-LABA, in comparison to formoterol beclomethasone, salmeterol fluticasone was found to increase the risk 7.49-fold for DED (OR: 7.49, CI: 1.48-35.75, p = 0.015).

CONCLUSIONS

Nebulizer delivery of steroids is associated with dry eye and cataracts. Smoking, ageing, and long-term inhaled steroid use have all been linked to an increased risk of cataracts. Longitudinal and larger sample size studies are needed to explore cause-effect relationships.

Glaucoma and Systemic Disease

Glaucoma is the leading cause of irreversible blindness in the world. Due to its potential to cause permanent vision loss, it is important to understand how systemic conditions and their respective treatments can be associated with or increase the risk for developing glaucoma. In this review, we examined the literature for up-to-date discussions and provided commentary on glaucoma, its pathophysiology, and associated risk factors. We discuss systemic diseases and the impact, risk, and mechanism for developing glaucoma, including pharmacologically induced glaucoma; inflammatory and auto-immune conditions; infectious, dermatologic, cardiovascular, pulmonary, renal, urologic, neurologic, psychiatric and systemic malignancies: intraocular tumors; as well as pediatric, and genetic conditions. The goal of our discussion of systemic conditions including their commonality, mechanisms, treatments, and associations with developing glaucoma is to emphasize the importance of ocular examinations and follow-up with the multidisciplinary teams involved in the care of each patient to prevent unnecessary vision-loss.

Ocular manifestations of common pulmonary diseases: a narrative review

Several pulmonary disorders can cause ocular involvement. Understanding these manifestations is critical for early diagnosis and treatment. Hence, we set out to examine the most common ocular manifestations of asthma, chronic obstructive pulmonary disease (COPD), sarcoidosis, obstructive sleep apnea (OSA), and lung cancer. Allergic keratoconjunctivitis and dry eye are two ocular manifestations of bronchial asthma. The inhaled corticosteroids used to treat asthma can cause cataract formation. COPD is associated with ocular microvascular changes as a result of chronic hypoxia and systemic inflammation spillover into the eyes. Its clinical significance, however, is unknown. Ocular involvement is common in sarcoidosis, occurring in 20% of cases of pulmonary sarcoidosis. It can affect nearly any anatomical structure of the eye. Obstructive sleep apnea has been linked to floppy eye syndrome, glaucoma, non-arteritic anterior ischemic optic neuropathy, keratoconus, retinal vein occlusion, and central serous retinopathy, according to research. However, while an association has been established, causality has yet to be established. The effect of positive airway pressure (PAP) therapy used to treat OSA on the aforementioned ocular conditions is unknown. PAP therapy can cause eye irritation and dryness. Lung cancer can affect the eyes through direct nerve invasion, ocular metastasis, or as part of a paraneoplastic syndrome. The goal of this narrative review is to raise awareness about the link between ocular and pulmonary disorders in order to aid in the early detection and treatment of these conditions.

Prevalence and Risk Factors of Glaucoma Among Chinese People.From the China Health and Retirement Longitudinal Study

PRCIS

This study demonstrated the prevalence of self-reported glaucoma and its strong association with pre-existing systemic chronic diseases in China using the baseline data from CHARLS, a nationwide population-based cohort.

PURPOSE

To estimate the prevalence of self-reported glaucoma and its risk factors using data from the China Health and Retirement Longitudinal Study (CHARLS).

MATERIALS AND METHODS

Data on age, sex, area of residence, education, marital status, health-related behaviors, and pre-existing comorbidities for this cross-sectional study were retrieved from the CHARLS for 17,713 subjects who completed a questionnaire between June 2011 and March 2012. The prevalence of glaucoma was estimated, and a multivariate weighted analysis was performed to estimate the odds ratios (ORs) of its risk factors.

RESULTS

Of 16,599 respondents (93.7%) who answered questions regarding glaucoma and their history of systemic chronic diseases, 314 (1.89%) reported having glaucoma before the index date. Qinghai and Beijing had the highest prevalence of glaucoma in China. Glaucoma was significantly associated with hypertension (OR 1.362 [95% confidence interval (CI) 1.801-2.470]), diabetes (OR 2.597 [95% CI 1.661-10.207]), dyslipidemia (OR 1.757 [95% CI 1.157-3.650]), lung disease (OR 2.098 [95% CI 1.674-6.527]), stroke (OR 5.278 [95% CI 1.094-25.462]), heart disease (OR 1.893 [95% CI 1.237-3.363]), and health-related behaviors such as smoking and alcohol consumption after adjusting for age, sex, area, education, marital status, and medical insurance.

CONCLUSIONS

Geographic variation in the prevalence of self-reported glaucoma and its strong association with pre-existing systemic chronic diseases were observed, suggesting that in addition to ophthalmological examinations, regular physical examinations are necessary for glaucoma patients, especially in areas of high incidence. Appropriate strategies to improve preventive measures for glaucoma are recommended for the Chinese population.

Impact of Inhaled and Intranasal Corticosteroids Exposure on the Risk of Ocular Hypertension and Glaucoma: A Systematic Review and Meta-Analysis

Purpose

Starting in 2019, the Global Initiative for Asthma recommended the use of inhaled corticosteroids (ICS) as part of reliever combination therapy in patients 12 years of age and older, thus dramatically increasing the population exposure to ICS. ICS and intranasal corticosteroids (INS) are commonly used for a variety of respiratory diseases. Chronic steroid use is a well-known risk factor for elevated intraocular pressure (IOP) and glaucoma regardless of route of administration. This study aimed to determine the reported risk of glaucoma, ocular hypertension (OHT) and IOP elevation associated with ICS and INS use.

Materials and Methods

Systematic literature search in MEDLINE, EMBASE, Cochrane, CINAHL, BIOSIS, and Web of Science databases from the date of inception identified studies that assess ocular outcomes related to glaucoma in ICS and INS users. Study selection, risk of bias assessment and data extraction were done independently in duplicate. Meta-analysis assessed glaucoma incidence, OHT incidence and IOP changes in patients using ICS and INS. Study adhered to PRISMA guidelines. Study protocol was registered with PROSPERO: CRD42020190241.

Results

Qualitative and quantitative analyses included 65 and 41 studies, respectively. Incidence of glaucoma was not significantly different in either ICS or INS users compared to control over 45,457 person-years of follow-up. Similarly, no significant difference in OHT incidence over 4431 person-years was detected. In studies reporting IOP, a significantly higher IOP was observed (0.69 mmHg) in 857 ICS or INS users compared to 615 controls. However, no significant increase in IOP was observed within ICS or INS users when compared to pre-treatment baseline.

Conclusion

Overall, use of ICS or INS does not significantly increase the incidence of glaucoma or OHT. However, ICS and INS patients had significantly higher IOPs compared to untreated patients. Awareness of these findings is significant in care of patients with additional risk factors for glaucoma.

Spanish COPD Guideline (GesEPOC) Update: Comorbidities, Self-Management and Palliative Care

The current health care models described in GesEPOC indicate the best way to make a correct diagnosis, the categorization of patients, the appropriate selection of the therapeutic strategy and the management and prevention of exacerbations. In addition, COPD involves several aspects that are crucial in an integrated approach to the health care of these patients. The evaluation of comorbidities in COPD patients represents a healthcare challenge. As part of a comprehensive assessment, the presence of comorbidities related to the clinical presentation, to some diagnostic technique or to some COPD-related treatments should be studied. Likewise, interventions on healthy lifestyle habits, adherence to complex treatments, developing skills to recognize the signs and symptoms of exacerbation, knowing what to do to prevent them and treat them within the framework of a self-management plan are also necessary. Finally, palliative care is one of the pillars in the comprehensive treatment of the COPD patient, seeking to prevent or treat the symptoms of a disease, the side effects of treatment, and the physical, psychological and social problems of patients and their caregivers. Therefore, the main objective of this palliative care is not to prolong life expectancy, but to improve its quality. This chapter of GesEPOC 2021 presents an update on the most important comorbidities, self-management strategies, and palliative care in COPD, and includes a recommendation on the use of opioids for the treatment of refractory dyspnea in COPD.
