The Influence of Tear Film Quality on Visual Function.

Background: The prevalence of dry eye disease (DED) is increasing globally, resulting in a variety of eye symptoms characterized by discomfort and visual disturbances. The accurate diagnosis of the disease is often challenging and complex, requiring specialized diagnostic tools. This study aimed to investigate the impact of tear film instability on visual function and to evaluate the value of post-blink blur time (PBBT) as an alternative method for assessing tear film stability.

Dry eye in contact lens wearers as a growing public health problem.

Background: The aim of this study is to analyze the relationship between the self-reported symptoms and objective signs of dry eye disease in long-term rigid gas-permeable (RGP) or soft contact lens (SCL) wearers.

Subjects And Methods: The study included 84 eyes of Caucasian RGP and SCL wearers between the age of 15 and 71 who wore contact lenses on a continuous daily basis for more than 1 year. Symptoms were assessed according to the Ocular Surface Disease Index (OSDI).

Body mass index: a risk factor for retinopathy in type 2 diabetic patients.

The aim of the study was to investigate whether body mass index (BMI) independently or in correlation with other risk factors is associated with diabetic retinopathy (DR) progression. The study included 545 patients with type 2 diabetes. According to DR status, they were divided into three groups: group 1 (no retinopathy; n = 296), group 2 (mild/moderate nonproliferative DR; n = 118), and group 3 (severe/very severe NPDR or proliferative DR; n = 131).
