Bulloch G, Seth I, Zhu Z, Sukumar S, McNab A. Ocular manifestations of obstructive sleep apnea: a systematic review and meta-analysis. Graefes Arch Clin Exp Ophthalmol 2024; 262:19-32. [PMID: 37227479 PMCID: PMC10806133 DOI: 10.1007/s00417-023-06103-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2022] [Revised: 03/22/2023] [Accepted: 05/08/2023] [Indexed: 05/26/2023] Open
Abstract
BACKGROUND The association of obstructive sleep apnea (OSA) with development of eye diseases is unclear. This current systematic review and meta-analysis attempts to summarize and analyze associations between OSA and ocular disorders in the literature. METHODS PubMed, EMBASE, Google Scholar, Web Of Science, and Scopus databases were searched from 1901 to July 2022 in accordance with the Preferred Reporting in Systematic Review & Meta-Analysis (PRISMA). Our primary outcome assessed the association between OSA and the odds of developing floppy eyelid syndrome (FES), glaucoma, non-arteritic anterior ischemic optic neuropathy (NAION), retinal vein occlusion (RVO), keratoconus (KC), idiopathic intracranial hypertension (IIH), age-related macular degeneration (AMD), and central serous chorioretinopathy (CSR) through odds ratio calculated at the 95% confidence interval. RESULTS Forty-nine studies were included for systematic review and meta-analysis. The pooled OR estimate was highest for NAION [3.98 (95% CI 2.38, 6.66)], followed by FES [3.68 (95% CI 2.18, 6.20)], RVO [2.71(95% CI 1.83, 4.00)], CSR [2.28 (95% CI 0.65, 7.97)], KC [1.87 (95% CI 1.16, 2.99)], glaucoma [1.49 (95% CI 1.16, 1.91)], IIH [1.29 (95% CI 0.33, 5.01)], and AMD [0.92 [95% CI 0.24, 3.58] All observed associations were significant (p < 0.001) aside from IIH and AMD. CONCLUSION OSA is significantly associated with NAION, FES, RVO, CSR, KC, and glaucoma. Clinicians should be informed of these associations so early recognition, diagnosis, and treatment of eye disorders can be addressed in at-risk groups, and early referral to ophthalmic services is made to prevent vision disturbances. Similarly, ophthalmologists seeing patients with any of these conditions should consider screening and referring patients for assessment of possible OSA.

Abstract
BACKGROUND Patients with obstructive sleep apnea (OSA) have a higher risk of developing vascular diseases. In this study, we evaluated the clinical profile of patients with OSA who develop retinal vein occlusion (RVO) compared with a population of OSA patients without RVO. METHODS We analyzed patients with OSA diagnosed with RVO (21 cases; mean of age 61 years. range 44-87 years. 67% men), belonging to a large cohort of people with long-term follow-up for RVO (up to 12 years). We compared them with 21 patients with OSA, without RVO, matched by age and gender, selected from the Sleep Unit Registry (control group). RESULTS There were no differences in the prevalence of arterial hypertension (AHT) or Diabetes mellitus (DM), but the RVO patients presented a higher diastolic blood pressure compared to controls (87.6±12.6 mmHg vs. 77.9±10.1 mmHg respectively). The polygraphic parameters were similar in both groups. The Apnea-Hypopnea Index (IHA) similar in both groups (30.4±20.9 RVO vs. 33.7±22.1 controls). In addition, RVO patients had a less favorable lipid profile, with higher total cholesterol (218±52 mg/dL vs. 179±41 mg/dL), higher LDL cholesterol (139±47 mg/dL vs. 107±32 mg/dL) and higher atherogenic indices: LDL/HDL (2.78±0.95 RVO vs. 2.03±0.67 controls) and total cholesterol/HDL (4.37±1.08 vs. 3.45±0.84). Among the cases, 81% had peripheral RVO (superior temporal branch in 20 out of 21 cases) and 19% had central RVO. A percentage of 62% of the cases received intravitreal antiangiogenic therapy and dexamethasone implants and 33% received argon laser photocoagulation. CONCLUSIONS Poor control of cardiovascular risk factors, particularly dyslipidemias, in patients with OSA may lead to the development of this ocular complication.

Abstract
AIM To detect retinal microvascular variations in obstructive sleep apnea syndrome patients. METHODS This prospective, observational case-control study included healthy controls and patients with mild, moderate, and severe obstructive sleep apnea syndrome. Vascular parameters, foveal avascular area, and flow areas in macula-centered, 6.00×6.00 mm2 scan size optical coherence tomography angiography images were compared. RESULTS The control group had the highest whole image, parafoveal, and perifoveal vessel density among the groups in both superficial and the deep capillary plexus (all P<0.05). Rapid eye movement sleep apnoea-hypopnoea index was reversely correlated with whole (Rho=-0.195, P=0.034), parafoveal (Rho=-0.242, P=0.008), perifoveal (Rho=-0.187, P=0.045) vessel density in the superficial capillary plexus, and whole (Rho=-0.186, P=0.046), parafoveal (Rho=-0.260, P=0.004), perifoveal (Rho=-0.189, P=0.043) vessel density in the deep capillary plexus, though the mean and non-rapid eye movement sleep apnoea-hypopnoea index related with only parafoveal vessel density in the superficial capillary plexus (Rho=-0.213, P=0.020; Rho=-0.191, P=0.038) and the deep capillary plexus (Rho=-0.254, P=0.005; Rho=-0.194, P=0.035). CONCLUSION This study shows decreased vessel density and its reverse correlation with the apnoea-hypopnoea index in patients with obstructive sleep apnea syndrome.

Abstract
BACKGROUND Previous studies suggest that sleep-disordered breathing (SDB) may be a potential risk factor of retinal vein occlusion (RVO). We conducted a meta-analysis to systematically explore the relationship between RVO and SDB. METHODS Observational studies assessing the relationship between SDB and RVO were retrieved by searches of electronic databases including the PubMed, Embase, Web of Science, China National Knowledge Infrastructure, and Wan Fang databases from database inception to August 9, 2023. In consideration of intra-study heterogeneity, a random-effects model was adopted to combine the results. RESULTS Seven studies (1 retrospective cohort and 6 case-control studies) were included in this meta-analysis, and among 36,628 adults included in those studies, 6452 (17.6%) had SDB. The combined results indicated that SDB was associated with RVO [risk ratio (RR): 1.92, 95% confidence interval (CI): 1.60-2.30, P < .001] with no significant heterogeneity (I2 = 0%). Subgroup analyses showed consistent relationships between SDB and any RVO (RR: 1.73, 95% CI: 1.13-2.28, P < .001), central RVO (RR: 2.20, 95% CI: 1.57-3.08, P < .001), and branch RVO (RR: 1.85, 95% CI: 1.15-2.99, P = .01). Moreover, the relationship was consistent among patients with mild (RR: 1.82, 95% CI: 1.32-2.53, P < .001), moderate (RR: 2.17, 95% CI: 1.65-2.85, P < .001), and severe SDB (RR: 2.66, 95% CI: 1.96-3.62, P < .001). The association was consistent in studies that adjusted for age and sex (RR: 2.17, 95% CI: 1.50-3.13, P < .001), and in studies with additional adjustment for comorbidities (RR: 1.78, 95% CI: 1.42-2.25, P < .001). CONCLUSION SDB is associated with RVO in adults.

Abstract
Retinal vein occlusion (RVO) is the second common cause of blindness following diabetic retinopathy. The manual screening of fundus images to detect RVO is time consuming. Deep-learning techniques have been used for screening RVO due to their outstanding performance in many applications. However, unlike other images, medical images have smaller lesions, which require a more elaborate approach. To provide patients with an accurate diagnosis, followed by timely and effective treatment, we developed an intelligent method for automatic RVO screening on fundus images. Swin Transformer learns the hierarchy of low-to high-level features like the convolutional neural network. However, Swin Transformer extracts features from fundus images through attention modules, which pay more attention to the interrelationship between the features and each other. The model is more universal, does not rely entirely on the data itself, and focuses not only on local information but has a diffusion mechanism from local to global. To suppress overfitting, we adopt a regularization strategy, label smoothing, which uses one-hot to add noise to reduce the weight of the categories of true sample labels when calculating the loss function. The choice of different models using a 5-fold cross-validation on our own datasets indicates that Swin Transformer performs better. The accuracy of classifying all datasets is 98.75 ± 0.000, and the accuracy of identifying MRVO, CRVO, BRVO, and normal, using the method proposed in the paper, is 94.49 ± 0.094, 99.98 ± 0.015, 98.88 ± 0.08, and 99.42 ± 0.012, respectively. The method will be useful to diagnose RVO and help decide grade through fundus images, which has the potency to provide patients with further diagnosis and treatment.

Abstract
Despite of inadequate evidence, previous studies have demonstrated a potential correlation between obstructive sleep apnea (OSA) and retinal vein occlusion (RVO). In this study, a meta-analysis is conducted to investigate the correlation between OSA and RVO. Databases are searched for relevant literatures up to July 14, 2021, including PubMed, Embase, Cochrane, Web of Science, CNKI, WanFang, VIP, and Chinese Biomedical Literature Database (CBM). The odds ratio (OR) and 95% confidence interval (CI) are estimated to evaluate the correlation between OSA and RVO. Six articles were finally enrolled, including 36,086 subjects from 5 case-controlled studies and 1 cohort study. It is clearly evident that the RVO risk is higher among OSA patients than non-OSA patients (OR = 3.24, 95% CI = 3.24). The results of sensitivity analysis indicate that the present meta-analysis is robust and reliable. Furthermore, Egger's test for publication bias is performed with P = 0.195, and the results reveal no significant publication bias. The findings demonstrate that OSA is significantly correlated with RVO, and OSA is a risk factor for RVO.

Abstract
PURPOSE To explore the risk factors for central retinal vein occlusion (CRVO) by comparing a large sample of patients with healthy controls. MATERIALS AND METHODS Multi-center case-control study. The study group includes patients affected by central retinal vein occlusion, confirmed angiographically, aged 50 years old or above (Group A). The control group includes healthy subjects without an history of retinal vein occlusion (Group B). Outcome measures: age, gender, active smoking, presence of uncontrolled arterial hypertension (uHTN), presence of the following comorbidities: diabetes mellitus type II (DMII), chronic liver disease (CLD), chronic kidney disease (CKD), thyroid disease (TD), systemic lupus erythematosus (SLE), hyperhomocystenemia (HHcy), dyslipidemia (DLip), carotid artery disease (CAD), glaucoma, atrial fibrillation (AF), migraine headache (MH), chronic obstructive pulmonary disease (COPD), obstructive sleep apnea syndrome (OSAS), history of myocardial infarction (MI). Odds-ratios were calculated with logistic regression analysis. RESULTS A total of 203 patients (Group A) and 339 controls (Group B). Statistically-significant differences were found for the following variables: age (OR: 1.109 [1.081-1.138], p < .001), active smoking (OR: 2.048 [1.210- 3.466], p < .008), DMII (OR: 4.533 [2.097-9.803], p < .001), HHcy (OR: 4.507 [2.477-10.001 ], p < .001), DLip (OR: 2.255 [1.352-3.762], p = .002), CAD (OR: 6.632 [2.944- 14.942], p < .001), glaucoma (OR: 4.656 [2.031-10.673], < .001), OSAS (OR: 1.744 [1.023-2.975], < .041), uHTN (OR: 3.656 [2.247-5.949], < .001). No statistically-significant differences were found for the other variables. CONCLUSIONS Older age, active smoking, as well as presence of DMII, HHcy, DLip, CAD, glaucoma, OSAS, and uHTN, all increase the risk for CRVO. A comprehensive assessment of patients with CRVO is paramount. Adequate control of all the aforementioned risk factors is likely of great significance in reducing the incidence of CRVO among the general population, and it likely plays an important role in improving the prognosis following the occlusive event.

Abstract
CITATION This review's objective was to synthesize the literature on the repercussions of obstructive sleep apnea (OSA) in the retinal vascular system. Two independent investigators conducted a search using the MEDLINE/PubMed database using the following terms: sleep apnea syndrome, obstructive sleep apnea, retina, vascular tortuosity, central serous chorioretinopathy, diabetes mellitus, and subfoveal choroidal thickness. Patients with OSA present increased vascular tortuosity compared with patients without OSA, decreased parafoveal and peripapillary vessel density, and increased retinal vein occlusion incidence. In central serous chorioretinopathy patients and patients who are poor responders to intravitreal anti-VEGF (-vascular endothelial growth factor) treatment for macular edema, OSA is more frequent. Macular choroidal thickness alterations are controversial, and OSA may worsen diabetic maculopathy, thus being a risk factor for diabetic retinopathy, proliferative diabetic retinopathy, and macular edema. OSA is a prevalent syndrome with many systemic vascular changes. The retina and choroid are the most affected ocular structures, with primarily vascular changes. New noninvasive technologies such as optical coherence tomography and optical coherence tomography angiography could help to better understand retinal structures and help clarify the ophthalmological repercussions of OSA.

Abstract
Obstructive sleep apnea (OSA) is characterized by frequent episodes of partial or complete obstruction of the airway during sleep causing repeated episodes of apnea. OSA is more prevalent in middle-aged and older adults. OSA is associated with numerous ocular manifestations, including retinal manifestations. Literature highlighted the clear association between OSA and numerous ocular conditions including glaucoma and papilledema. This comprehensive and narrative review aims to summarize up-to-date clinical research concerning the association of OSA and vascular conditions that affect the retina. OSA is associated with the central serous chorioretinopathy (CSC), retinal vein occlusion (RVO), hypertensive retinopathy (HTRP) and development of diabetic retinopathy (DR). Sympathetic activation, hypoxia, and hormonal dysregulation all lead to serious retinal vascular conditions that will worsen OSA patients’ quality of life. It is important to refer patients with newly diagnosed OSA to an ophthalmology clinic for the appropriate test.

Abstract
Obstructive sleep apnea (OSA), the most common form of sleep-disordered breathing, is characterized by repetitive episodes of paused breathing during sleep, which in turn induces transient nocturnal hypoxia and hypercapnia. The high prevalence of OSA and its associated health consequences place a heavy burden on the healthcare system. In particular, the consequent episodic oxygenic desaturation/reoxygenation series and arousals from sleep in patients with OSA have the potential to trigger oxidative stress, elevated systemic inflammatory responses, and autonomic dysfunction with sympathetic activation. Given these adverse side-effects, OSA is highly correlated to many eye diseases that are common in everyday ophthalmic practices. Some of these ocular consequences are reversible, but they may permanently threaten a patient’s vision if not treated appropriately. Here, this article seeks to review the ocular consequences and potential pathophysiologic associations in patients with OSA. Understanding these OSA-related eye diseases may help clinicians provide comprehensive care to their patients.

Venkatesh R, Pereira A, Aseem A, Jain K, Sangai S, Shetty R, Yadav NK. Association Between Sleep Apnea Risk Score and Retinal Microvasculature Using Optical Coherence Tomography Angiography. Am J Ophthalmol 2021; 221:55-64. [PMID: 32882221 DOI: 10.1016/j.ajo.2020.08.037] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2020] [Revised: 08/16/2020] [Accepted: 08/24/2020] [Indexed: 12/30/2022]
Abstract
PURPOSE To investigate the retinal vessel changes at peripapillary and parafoveal regions using optical coherence tomography angiography in patients with varying obstructive sleep apnea syndrome (OSAS) risk, identified by the STOP-BANG questionnaire. DESIGN Prospective, hospital-based cross-sectional study. METHODS Participants were divided into 3 groups based on the OSAS risk score. Flow areas and vessel densities were calculated at peripapillary and parafoveal regions using optical coherence tomography angiography. Microvasculature changes between the 3 groups and correlation between OSAS risk score and vascular changes were calculated. RESULTS Six hundred and six eyes of 303 patients were included in groups 1 (n = 96), 2 (n = 135), and 3 (n = 72). In patients with high OSAS risk, an increase in flow areas (P = .011) and vessel densities (P = .002) in superficial capillary plexus was noted. In contrast, flow areas (P = .003) and vessel densities (P < .000) in deep capillary plexus were reduced. Positive correlation was noted between sleep scores and vessel densities in superficial capillary plexus (P = .04). Negative correlation was noted between sleep scores and flow areas (P = .003) and vessel densities (P ≤ .001) in deep capillary plexus. CONCLUSION The sleep apnea questionnaire is an easy method of identifying the disease severity stage, but polysomnography still remains the definitive gold standard. Optical coherence tomography angiography shows some associations with disease severity, but it cannot be used unambiguously to distinguish the severity of sleep apnea.

Abstract
PURPOSE OF REVIEW The aim of this article is to summarize up-to-date research on the effects of obstructive sleep apnea (OSA) on retinal vascular conditions. RECENT FINDINGS OSA is associated with the development of diabetic retinopathy, retinal vein occlusion, and central serous chorioretinopathy. The severity of OSA and biomarkers such as the apnea-hypopnea index (AHI) correlate with the severity of retinal disease. Dysregulation of circadian locomotor output cycles kaput (CLOCK) genes that govern circadian rhythm is associated with development of proliferative retinal disease. SUMMARY OSA and retinal vascular disease have a high cost burden on the healthcare system. OSA creates systemic changes and hypoxic conditions that may incite or exacerbate retinal vascular diseases. Retinal changes may be the first clinical manifestation of otherwise undiagnosed OSA, so it is important to refer patients with new-onset retinal vascular disease for appropriate sleep testing.

Abstract
OBJECTIVE To evaluate the prevalence and varying severity of obstructive sleep apnea (OSA) amongst those newly diagnosed with retinal vein occlusion (RVO), and screen patients with the use of 2 in-office-administered questionnaires validated against polysomnography. DESIGN Prospective cross-sectional study. PARTICIPANTS Consecutive adult patients (≥18 years of age) with a new diagnosis of RVO confirmed with intravenous fluorescein angiography were enrolled. METHODS The study was conducted at a tertiary academic centre between March 22, 2017, and April 7, 2018. Patients completed the Berlin and STOP-BANG questionnaires screening for OSA at presentation. Diagnostic test properties of the 2 questionnaires compared with polysomnography at a certified sleep laboratory centre as the gold standard for detection of OSA were calculated. RESULTS A total of 27 patients (37% females) with a mean (standard deviation) age of 69.6 (11.5) years completed the study. The diagnosis of OSA based on polysomnography was made in 96% (41% severe OSA) of patients with RVO. The Berlin questionnaire had a sensitivity of 43% (confidence interval [CI]: 22%-66%) and specificity of 67% (CI: 22%-96%). The STOP-BANG questionnaire had a sensitivity of 86% (CI: 64%-97%) and specificity of 50% (CI: 12%-88%). CONCLUSIONS Given the high prevalence of severe OSA amongst those with a new diagnosis of RVO, all patients should be strongly considered for polysomnography. The use of in-office questionnaires may aid in triaging urgency of referrals.
