Protective effect of retinal ischemia by blockers of voltage-dependent calcium channels and intracellular calcium stores.

In the present study, the neuroprotective effect of blockers of voltage-dependent calcium channels (VDCC) and intracellular calcium stores on retinal ischemic damage induced by oxygen deprivation-low glucose insult (ODLG) was investigated. Retinal damage induced by ODLG was dependent on the calcium concentration in the perfusion medium. When incubated in medium containing 2.

[Diabetic retinopathy].

Diabetic retinopathy is a frequently observed complication in both type 1 and type 2 diabetes, specially in patients with long term disease and poor glicemic control. Irreversible visual loss appears at the final stages of diabetic retinopathy and it is considered one of the most tragic of diabetic complications.
