Predicting the risk of diabetic retinopathy in type 2 diabetic patients.

Aims: Diabetic retinopathy (DR) is often asymptomatic even in its more advanced stages. Timely and repeated screening for DR avoids a late diagnosis of DR, but the high number of diabetic patients precludes a frequent screening; thus, the need for a method to identify patients at higher risk for DR becomes crucial.

Methods: A prospective analysis of 5034 type 2 diabetic patients followed from 1996 to 2007 and not affected by retinopathy at the time of the recruitment was performed.

[Relation of asthenopia and some ophthalmological, neuropsychological, and musculoskeletal parameters in workers assigned to video display terminals].

Background: Since the use of video display units (VDU) has become widespread in the workplace, more and more research has been conducted to evaluate the possible onset of adverse effects.

Objectives: We carried out a multidisciplinary investigation on a group of 660 VDU operators working for a service agency, aimed at analysing the relationship between ophthalmological, musculoskeletal and neuropsychological parameters and asthenopia.

Methods: In this study we propose a method for a qualitative and quantitative evaluation of the asthenopic syndrome based on data collected with an easy semi-structured questionnaire.
