High myopia is one of the risk factors for glaucoma, which is often accompanied by abnormalities in the fundus due to excessive stretching. The object of the study is to determine correlation between cup ratio and optic nerve disc with high myopia. This is a non-experimental research, analytic observational  with cross-sectional study design. The subjects were patients with myopia with more than – 6.00 diopters at the Kebumen Eye Center Clinic and Purbowangi Gombong Hospital. Data collection was carried out in January - August 2019. The respondents  were 30 people, consisting of 14 men (46.7%), 16 women (53.3%), with an average age of 33.07 ± 18.04 years. Mean refraction of right eye (OD / Ocular Dextra) were -10.72 ± 4.82 diopters and left eye (OS / Ocular Sinistra) were -10.27 ± 4.52 diopters. The results of the correlation test using Spearman Test showed that there is no significant correlation (OD p = 0.115, OS p = 0.118) between the cup ratio and optic nerve disk with high myopia. It conclude that there is no significant correlation between cup ratio and optic nerve disc with high myopia.

Abstract Background Our study aimed to explore the prevalence and risk factors of refractive error (RE) in Han and Tibetan population aged 50–79 years in Xining and surrounding areas in Qinghai Province on Qinghai-Tibet Plateau. Methods As part of the China National Health Survey, our cross-sectional study compared the age-adjusted prevalence of RE in Han and Tibetan older adults aged 50–79 years in Xining and surrounding areas. A multivariate logistic regression model was used to identify risk factors for myopia and hyperopia. Results Among 769 Han participants and 476 Tibetan participants, the age-adjusted prevalence of myopia (spherical equivalent (SE) < − 0.5D), hyperopia (SE > + 0.5D), high myopia (SE < -6.0D) and astigmatism (cylindrical equivalent > = 0.5D) is 28.56, 22.82, 2.80, and 69.38%. Han participants have higher age-adjusted prevalence of myopia (32.93% vs 21.64%, p < 0.001), high myopia (3.93% vs 1.02%, p = 0.001) and astigmatism (72.14% vs 64.94%, p = 0.021) compared to Tibetan participants. Being Tibetan is the protective factor of myopia compared to being Han (OR 0.58, 95%CI 0.42–0.79, p < 0.001). Older age (p = 0.032), longer time length in rural area (p = 0.048), undergraduate/graduate education level (p = 0.031), lighter active level (p = 0.007) and lower BMI (p = 0.015) are risk factors for myopia. Older age (all p < 0.001) and pterygium status of the same eye (p = 0.013) also increase the hyperopia risk. Conclusions Our study found an overall prevalence of myopia of 28.56% in Xining and surrounding areas in adults older than 50 years. Han population has higher myopia risk than Tibetan population. More medical and social resources should be allocated to improve the vision and life quality of older adults.

Attributable to the nature of their occupation, fishermen are consistently exposed to the hazardous UV radiation which not only affects the skin but also the eye. The objective of this study is to determine the prevalence of photoconjunctivits and conjunctival lesions among fishermen in Jazan and the association with socio-demographic background and occupational history. This study employed a cross-sectional study design conducted in the Jazan region of Saudi Arabia among 511 fishermen. Data collection using a set of questionnaire was assisted by interviewer which is ensued by an eye examination. The prevalence of the photo conjunctivitis was found to be 4.3% and that of conjunctival lesions at 0.8%. An association was seen between the prevalence of photoconjunctivitis and conjunctival lesions to the exposure of sunlight.

Nathues C, Janssen E, Duengelhoef A et al. Cross-sectional study on risk factors for Porcine Reproductive and Respiratory Syndrome virus sow herd instability in German breeding herds. Acta Vet Scand 2018; 60 (1): 1–8 In mit PRRSV (Porcine Reproductive and Respiratory Syndrom Virus) infizierten Schweinebeständen zeigen die Tiere oftmals ernsthafte klinische Symptome. Die Schwere der Symptomatik hängt von der Virulenz der jeweiligen Virusstämme ab. Deshalb ist die Impfung gegen diesen Erreger sinnvoll und wird empfohlen, auch wenn sie nicht immer klinische Fälle verhindert bzw. das Virus vollends eliminiert. Aufgrund dessen rückt die Prävention durch Verbesserung der innerbetrieblichen Abläufe zunehmend in den Fokus. Um solche Maßnahmen erfolgreich etablieren zu können, ist es wichtig, den epidemiologischen Status der Herde und mögliche Risikofaktoren zu kennen. Ziel der Studie war deshalb, die Prävalenz der Infektion in Sauenbetrieben in Norddeutschland zu eruieren und verschiedene Arbeitsabläufe hinsichtlich des Risikos der Erregerverbreitung zu untersuchen.
