Background: Monoclonal gammopathy (MG) is characterized by monoclonal protein overproduction, potentially leading to the development of hyperviscosity syndrome.

Objective: To assess retinal circulation using optical coherence tomography angiography (OCTA) parameters in patients with monoclonal gammopathy.

Methods: OCTA measurements were performed using the Optovue AngioVue system by examining 44 eyes of 27 patients with MG and 62 eyes of 36 control subjects.

The aim of our review article was to summarize the current literature on Stevens-Johnson syndrome (SJS) and its severe form, toxic epidermal necrolysis (TEN). SJS/TEN is a serious, rare multi-system, immune-mediated, mucocutaneous disease with a significant mortality rate that can lead to severe ocular surface sequelae and even to bilateral blindness. Restoration of the ocular surface in acute and chronic SJS/TEN is challenging.

To compare the macular morphology of good and poor responders to eplerenone treatment in chronic central serous chorioretinopathy (CSCR) patients. Thirty eyes of 29 patients with chronic CSCR were treated with 50 mg/day oral eplerenone and followed up for 1 year. The integrity of outer retinal layers at baseline was assessed using optical coherence tomography.

Cognitive impairment and dementia are major medical, social, and economic public health issues worldwide with significant implications for life quality in older adults. The leading causes are Alzheimer's disease (AD) and vascular cognitive impairment/dementia (VCID). In both conditions, pathological alterations of the cerebral microcirculation play a critical pathogenic role.

Background/aims: The purpose of this study was to estimate the total healthcare cost associated with diabetic retinopathy (DR) in the population aged 18 years and older in Hungary, and its projection for the year 2045.

Methods: A cost model was developed based on the standardised rapid assessment of avoidable blindness with the diabetic retinopathy module (RAAB+DRM) methodology and recently reported prevalent-based cost of illness model. Projection for 2045 was made based on the estimation for increasing diabetes mellitus (DM) prevalence of the International Diabetes Federation.

Systemic medications of various diseases can have adverse effects on the eye that range from asymptomatic lesions to potentially blinding complications such as toxic retinopathy and optic neuropathy. In the course of ophthalmological screening, with the early detection of toxic effects, the majority of drug-induced eye disorders can be prevented and even be reversed. Our review focuses on major drugs with common and significant ocular side effects.
