Eye Axial Length: Is There a Protective Link to Diabetic Retinopathy?

Optics and Optometry Division, Investigative Techniques in Optometry Research Group, Department of Biomedical Sciences, University of West Attica, Athens, GRC.
Diabetic retinopathy (DR) is a leading cause of vision impairment and blindness globally, particularly among working-age adults. As the prevalence of diabetes continues to rise, understanding factors that influence DR development and progression is increasingly important. Recent studies suggest a protective association between a longer axial length (AL) of the eye and the risk of DR, particularly in myopic individuals.

BACKGROUND Identifying patients at higher risk of acute ischemic cerebrovascular events (AICE) following central retinal artery occlusion (CRAO) is crucial for secondary prevention of stroke. This study aimed to investigate whether a low ankle-brachial index value is associated with an increased risk of AICE after CRAO. MATERIAL AND METHODS We prospectively analyzed patients who were admitted to our hospital because of CRAO between February 2019 and March 2023 and whose ankle-brachial index was no greater than 1.

Inherited retinal dystrophies (IRD) are the most frequent cause for severe visual loss in the working age. The heterogeneous group of IRDs is associated with loss of visual function and has a severe impact on personal and familial life. Early diagnosis is of high relevance for patients and their families, to facilitate possible therapies and professional help for the individual situation.

Pathogenic mutations that cause rhodopsin misfolding lead to a spectrum of currently untreatable blinding diseases collectively termed retinitis pigmentosa. Small molecules to correct rhodopsin misfolding are therefore urgently needed. In this study, we utilized virtual screening to search for drug-like molecules that bind to the orthosteric site of rod opsin and improve its folding and trafficking.

Retinal diseases can severely impair vision and even lead to blindness, posing significant threats to both physical and mental health. Physical retinal regenerative therapies are poised to revolutionize the treatment of various disorders associated with blindness. However, these therapies must overcome the challenges posed by the protective inner and outer blood‒retinal barriers.
