Correlations between dyslipidemia and retinal parameters measured with Angio-OCT in type II diabetics without diabetic retinopathy.

Aim: To analyze the relationship between lipoproteins such as total cholesterol, LDL-c, TG, and retinal parameters in patients with DM type II without signs of DR.

Method: A case-control study, consisting of 2 groups. A group of 64 patients with type II diabetes without signs of DR and a control group of 24 healthy subjects.

The role of vitamin D in the onset and progression of diabetic retinopathy.

Having a classical role in the regulation of calcium homeostasis in skeletal system, vitamin D has also been recognized as being involved in the activity of the immune system, as well as in the pathology of the visual analyzer. Thus, regarding the function of vitamin D in the eye, this is supported by the identification of vitamin D receptors (VDR) in several structures of the eyeball, such as corneal epithelial and endothelial cells, ciliary body and retinal cells. One of the ophthalmological pathologies in which vitamin D plays an important role is diabetic retinopathy, both through its effects on the immune system (reduction of the pro-inflammatory cytokines - IL-1, IL-6, IL-012, TNF alpha, and stimulation of anti-inflammatory cytokines IL-10), as well as by reducing the level of vascular endothelial growth factor (VEGF) and thus inhibiting retinal neovascularization.

[Ocular toxocariasis--case report].

Ocular Toxocariasis is a parasitosis caused by Toxocara catis/canis larvae localized in the eye. The most frequent clinical manifestations are the central retinal granuloma, peripheral retinal granuloma and chronic endophthalmitis. Secondary complications due to the presence of parasite in the posterior segment of the eye may have significant consequences on visual function.
