Regular physical exercise is known to lower the incidence of age-related eye diseases. We aimed to assess the acute chorioretinal alterations in older adults following intense physical strain. Seventeen senior elite athletes were recruited who underwent an aerobic exercise on a cycle ergometer and macular scanning by optical coherence tomography.

However, there are only few data on the acute effects of physical exercise on the retina and choroid. Our aim was the in vivo examination of chorioretinal alterations following short intense physical activity by spectral domain optical coherence tomography (SD-OCT).

Methods: Retrospective analysis was performed on 47 eyes of 47 patients with keratoconus using the Pentacam HR Scheimpflug camera before and 1, 3, 6 and 12 months after cross-linking. Corneal backscattered light values in grey scale unit were recorded in the anterior, center and posterior corneal layers and in four concentric rings.
Purpose: In diabetic subjects, early visual functional alterations such as color vision deficiencies (CVDs) are known to precede clinically apparent diabetic retinopathy. Prominent photoreceptor outer segment degeneration and an increase in the number of retinal dual cones (co-expressing S- and M-opsins simultaneously) have been described in diabetic rat models, suggesting a connection with the development of CVDs. As cone opsin expression is controlled by thyroid hormones, we investigated the diabetic retina in association with thyroid hormone alterations.

A Meibom-mirigyek kóros működése miatt a termelt lipid nem oszlik el megfelelően a szemfelszínen, így a könnyfilm párolgása fokozódik.

Methods: A rapid assessment of avoidable blindness (RAAB) was conducted. A total of 3523 eligible people were randomly selected and examined.
There is only limited information available on the effects of physical exercise on the posterior pole. Retinal circulation is autoregulated similarly to the brain vasculature in order to provide constant flow and thus constant nutrition of the inner retinal structures while the choroid is mostly controlled by the sympathetic nervous system. The available data show that physical exercise may indeed have a positive effect on the retina and visual function.

Methods: A total of 3523 people aged 50 years or older were examined at their homes in 105 randomly selected clusters in Hungary. During the 4-month-long field work, five teams visited the clusters.
Aim: The aim of this study was to estimate the prevalence and causes of blindness, severe visual impairment (SVI), moderate visual impairment (MVI), and early visual impairment (EVI) and its causes in an established market economy of Europe.
Design: A cross-sectional population-based survey.
Methods: A sample size of 3675 was calculated using the standard Rapid Assessment of Avoidable Blindness (RAAB) software in Hungary.
Introduction: Diabetes mellitus (DM) is one of the main causes of blindness among persons aged 50 years and older.
Aim: The purpose of our survey was to estimate the prevalence of DM and diabetic retinopathy (DR), as well as to assess the coverage of diabetic eye care services in different regions of Hungary.
Method: In 105 clusters, 3675 people aged 50 years and older were included in the survey.
Background/aims: The purpose of this study was to estimate the prevalence of diabetes mellitus (DM) and diabetic retinopathy (DR) in the population aged 50 years and older in Hungary, and to assess the coverage of diabetic eye care services.
Methods: In total, 105 clusters of 35 people aged 50 years or older were randomly selected. The standardised rapid assessment of avoidable blindness (RAAB) with the diabetic retinopathy module (DRM) was used.
Background: Acute severe postoperative endophthalmitis may lead to severe vision loss. The aim of this study was the analysis of macular microstructure imaged by spectral domain optical coherence tomography in patients after pars plana vitrectomy due to postcataract endophthalmitis.
Methods: A cross sectional study was carried out in 17 patients who had cataract surgery in both eyes and underwent unilateral pars plana vitrectomy due to postcataract endophthalmitis.
Aims: Transient ischemia of osteoporotic bones during elective orthopedic surgery or fracture repair carries risks for serious complications, and estrogen loss or replacement has a potential to influence ischemia-reperfusion-induced inflammatory activation. To clarify this, we investigated the periosteal inflammatory changes in a clinically relevant time frame in ovariectomized rats, an experimental model of postmenopausal bone loss. Furthermore, the effects of chronic estrogen supplementation on the postischemic local and systemic inflammatory reactions were assessed.
