Abstract
Purpose To identify the association between the choroidal thickness (ChT) with age and axial length (AL) under different refractive errors (REs) in Chinese adults. Methods Swept-source optical coherence tomography was used to measure ChT in 2126 right eyes of 2126 participants. The participants were classified as having pathologic myopia (PM), high myopia without PM (HM), low myopia (LM), and nonmyopia (non-M) according to their REs and META-PM (the Meta-Analysis of Pathologic Myopia) classification criteria. Results The mean age was 52.49 ± 20.39 years (range, 18−93 years), and the mean RE was −5.27 ± 5.37 diopters (D; range, −25.5 to +7.75 D). The mean average ChT was 159.25 ± 80.75 µm and decreased in a linear relationship from non-M to PM (190.04 ± 72.64 µm to 60.99 ± 37.58 µm, P < 0.001). A significant decline in ChT was noted between 50 and 70 years (r = −0.302, P < 0.001) and less rapidly after the age of 70 years (r = −0.105, P = 0.024). No correlation was noted between age and ChT under 50 years (P = 0.260). A significantly higher association with AL was noted in the central fovea (βHM = −23.92, βLM = −23.88, βNon-M = −18.80, all P < 0.001) and parafoveal ChT (βHM = −22.87, βLM = −22.31, βNon-M = −18.61, all P < 0.001) when compared with the perifoveal region (βHM = −19.80, βLM = −18.29, βNon-M = −13.95, all P < 0.001). Within each group of PM, HM, LM, and non-M, regression analysis showed that the coefficients of age and AL with different macular regions of ChT varied significantly. Conclusions ChT was negatively correlated with age after 50 years. The thinning of the choroid was more prominent in the center and parafoveal regions as AL increased. Varied distributions of ChT decrease associated with AL and age were noted among different refractive groups.

Abstract
Background To investigate the associations of lens power with age, axial length (AL), and Type 2 diabetes mellitus (DM) in Chinese adults aged 50 and above. Methods Random clustering sampling was used to identify adults aged 50 years and above in urban regions of Shanghai. The participants underwent a comprehensive ophthalmic examination including subjective refraction, autorefraction, and IOL-Master. The crystalline lens power was calculated using Bennett’s formula. Results A total of 4177 adults were included. A linear decrease in lens power was observed both with age and with AL, followed by a stop of lens power loss after the age of 70 or when AL ≥ 25 mm, respectively. Participants with Type 2 DM presented higher lens power (0.43 diopter (D), p < 0.001) and thicker lens thickness (0.06 mm, p < 0.001). In multivariate regression models, there was a positive correlation between lens power and Type 2 DM when age < 75 years (p < 0.001) or AL < 25 mm (p < 0.001) after adjusting for other factors, while no significant association was found in participants aged ≥ 75 years (p = 0.122) or with AL ≥ 25 mm (p = 0.172). Conclusions The lens power in adults aged 50 and above exhibited two stages with age and with AL. Type 2 DM caused an increase in lens power, which was not seen in participants aged ≥ 75 years or with AL ≥ 25 mm.

Abstract
Purpose To determine the risk between degree of myopia and myopic macular degeneration (MMD), retinal detachment (RD), cataract, open angle glaucoma (OAG), and blindness. Methods A systematic review and meta-analyses of studies published before June 2019 on myopia complications. Odds ratios (OR) per complication and spherical equivalent (SER) degree (low myopia SER < -0.5 to > -3.00 diopter [D]; moderate myopia SER ≤ -3.00 to > -6.00 D; high myopia SER ≤ -6.00 D) were calculated using fixed and random effects models. Results Low, moderate, and high myopia were all associated with increased risks of MMD (OR, 13.57, 95% confidence interval [CI], 6.18-29.79; OR, 72.74, 95% CI, 33.18-159.48; OR, 845.08, 95% CI, 230.05-3104.34, respectively); RD (OR, 3.15, 95% CI, 1.92-5.17; OR, 8.74, 95% CI, 7.28-10.50; OR, 12.62, 95% CI, 6.65-23.94, respectively); posterior subcapsular cataract (OR, 1.56, 95% CI, 1.32-1.84; OR, 2.55, 95% CI, 1.98-3.28; OR, 4.55, 95% CI, 2.66-7.75, respectively); nuclear cataract (OR, 1.79, 95% CI, 1.08-2.97; OR, 2.39, 95% CI, 1.03-5.55; OR, 2.87, 95% CI, 1.43-5.73, respectively); and OAG (OR, 1.59, 95% CI, 1.33-1.91; OR, 2.92, 95% CI, 1.89-4.52 for low and moderate/high myopia, respectively). The risk of visual impairment was strongly related to longer axial length, higher myopia degree, and age older than 60 years (OR, 1.71, 95% CI, 1.07-2.74; OR, 5.54, 95% CI, 3.12-9.85; and OR, 87.63, 95% CI, 34.50-222.58 for low, moderate, and high myopia in participants aged >60 years, respectively). Conclusions Although high myopia carries the highest risk of complications and visual impairment, low and moderate myopia also have considerable risks. These estimates should alert policy makers and health care professionals to make myopia a priority for prevention and treatment.

Abstract
PURPOSE To determine the effect of main morphological types and grades of age-related cataracts on refractive error. METHODS We measured 276 subjects with optical compensation prior to the development of cataract. We evaluated 224 eyes with nuclear cataract, 125 with cortical cataract, and 103 with posterior subcapsular (PSC) cataract classified with LOCSIII. We measured visual acuity (VA) with their spectacles and best-corrected visual acuity (BCVA) with chart in decimal scale to obtain the optimal compensation with cataract. We evaluated the differences between compensations. RESULTS A significant myopic shift was observed in nuclear cataract from low to mild grade (p=0.031), the same as for PSC cataract from mild to advanced grade (p=0.025). No significant changes were found for cortical cataract (p=0.462). Regarding astigmatism, we observed power changes in cortical cataract from low to mild grade (p=0.03) and axis changes in PSC from low to mild grade (p=0.02) and in nuclear cataract from mild to advanced grade (p=0.02). CONCLUSIONS Cataract produces changes in patient's compensation which depend on severity and type of cataract. For nuclear and PSC cataract, we observed that the higher the grade of severity, the greater the myopic shift. Power astigmatic changes were found in cortical cataract and axis changes in PSC and nuclear cataract.

Abstract
PURPOSE To examine if myopia is a risk factor for age-related cataract. DESIGN Systematic review and meta-analysis. METHODS A systematic review of the literature was performed using PubMed and Embase from their inception to March 2013 for population-based studies with data on myopia and age-related cataract, including nuclear, cortical, and posterior subcapsular (PSC) cataract. Separate meta-analyses for case-control/cross-sectional studies and cohort studies were conducted using random-effects models, with results reported as adjusted odds ratios (ORs) and relative risks (RRs), respectively. RESULTS A total of 38 007 subjects aged 30-97 years from 12 population-based studies were included in the meta-analysis. Meta-analysis of the 7 cross-sectional studies and 1 case-control study confirmed that myopia was associated with increasingly prevalent nuclear (pooled OR 2.81, 95% CI 1.94-4.06) and PSC cataract (pooled OR 1.93, 95% CI 1.49-2.49) but not with cortical cataract (pooled OR 1.08, 95% CI 0.90-1.30). Meta-analysis from 3 or 4 cohort studies showed nonsignificant associations of myopia with incident nuclear (pooled RR 1.25, 95% CI 0.71-2.21), cortical (pooled RR 1.21, 95% CI 0.67-2.19), and PSC cataract (pooled RR 1.26, 95% CI 0.92-1.74). CONCLUSIONS The associations of myopia with prevalent nuclear and PSC cataract are confirmed in meta-analysis of 8 study findings. The association of myopia with incidence of age-related cataract could not be confirmed in meta-analysis of 4 study findings.

Abstract
BACKGROUND To assess the association between refractive errors and the 10-year incidence of cataract and cataract surgery. DESIGN Population-based prospective study. PARTICIPANTS Three thousand six hundred fifty-four persons aged 49+ years living in a well-defined geographical region were examined at baseline; 2564 were re-examined after 5 and/or 10 years. METHODS Baseline refractive error was measured using autorefraction with subjective refinement. Lens photographs were taken at each visit and assessed using the Wisconsin Cataract Grading System. MAIN OUTCOME MEASURES Long-term incidence of cataract and cataract surgery. RESULTS Compared with emmetropia, high myopia was associated with increased incidence of nuclear cataract (adjusted odds ratio 3.01, 95% confidence intervals 1.35-6.71). Low (odds ratio 1.86, confidence interval 1.03-3.35) and high myopia (odds ratio 7.80, confidence interval 3.51-17.35) were significantly associated with higher incidence of posterior subcapsular cataract. Low, moderate and high myopia were associated with increased incidence of cataract surgery (odds ratio 2.54, confidence interval 1.76-3.68; odds ratio 2.61, confidence interval 1.45-4.69; and odds ratio 4.81, confidence interval 2.33-9.93, respectively). Either any (odds ratio 1.35, confidence interval 1.08-1.69) or moderate hyperopia (odds ratio 1.76, confidence interval 1.32-2.34) was associated with increased incidence of nuclear cataract. CONCLUSION Our longitudinal study confirms the association between myopia and an increased risk of nuclear and posterior subcapsular cataract. It also suggests that hyperopia may increase the risk of nuclear cataract.

Abstract
Cluster headache (CH) consists of attacks of severe, unilateral orbital/supraorbital/temporal pain, lasting for 15-180 min, occurring once or more times a day, and associated with ipsilateral conjunctival injection, lacrimation and other symptoms. Cataract is clouding of the lens of the eye causing a progressive and painless loss of vision. We describe the cases of two men (not relative, but with the same last name, which originates from north-eastern Italy) that in young adult age, after years of suffering from chronic CH, developed cataract on the same side of the pain attacks. Patient 1 was diagnosed as having cataract 18 years after the onset of episodic (and subsequently chronic) CH. Patient 2 began suffering from chronic CH at the age of 44 years and after 8 years he developed cataract. This is the first report of cataract in patient suffering of CH and occurring in the eye affected by the pain attack.
