The role of red blood cell characteristics and viscosity in sickle cell retinopathy and maculopathy

British Journal of Haematology, EarlyView.
Sickle cell retinopathy and maculopathy are common ocular complications of sickle cell disease. This study assessed the contribution of red blood cell characteristics and blood viscosity to their development. HbSC patients with proliferative retinopathy showed a lower delta elongation index and point of sickling, while no link was found between whole ...

Hereditary Vitreoretinopathies: Molecular Diagnosis, Clinical Presentation and Management

Clinical &Experimental Ophthalmology, Volume 53, Issue 3, Page 281-291, April 2025.
ABSTRACT Hereditary vitreoretinopathies (HVRs), also known as hereditary vitreoretinal degenerations comprise a heterogeneous group of inherited disorders of the retina and vitreous, collectively and variably characterised by vitreal abnormalities, such as fibrillary condensations, liquefaction or membranes, as well as peripheral retinal abnormalities,

A complementary method for automated detection of microaneurysms in fluorescein angiography fundus images to assess diabetic retinopathy [PDF]

Pattern Recognition, 2013, 2019
Early detection of microaneurysms (MAs), the first sign of Diabetic Retinopathy (DR), is an essential first step in automated detection of DR to prevent vision loss and blindness. This study presents a novel and different algorithm for automatic detection of MAs in fluorescein angiography (FA) fundus images, based on Radon transform (RT) and multi ...

Tetrahedral Framework Nucleic Acid‐Based Delivery of DJ‐1‐saRNA Prevent Retinal Ischaemia–Reperfusion Injury via Inhibiting Ferroptosis

Cell Proliferation, EarlyView.
Illustration of the preparation of tFNAs‐DJ‐1 saRNAs complex and its inhibitory effects on ferroptosis in R28 and retina. ABSTRACT Retinal ischaemia/reperfusion injury (RI/RI) is the primary pathophysiological mechanism underlying retinal ischaemic diseases, potentially resulting in significant and irreversible visual impairment.
