Retinal microglia protect against vascular damage in a mouse model of retinopathy of prematurity

Frontiers in Pharmacology, 2022
Retinopathy of prematurity (ROP) is a common cause of blindness in preterm babies. As a hypoxia-induced eye disease characterized by neovascularization, its association with retinal microglia has been noted but not well documented.

Retinal vessel oxygen saturation and vessel diameter in retinitis pigmentosa [PDF]

Acta Ophthalmologica, 2014
AbstractPurposeTo assess retinal vessel oxygen saturation and retinal vessel diameter in retinitis pigmentosa.MethodsA retinal oximeter (Oxymap ehf., Reykjavik, Iceland) was used to measure retinal vessel oxygen saturation and vessel diameter in ten patients with retinitis pigmentosa (RP) (mean age 49 years, range 23–71 years).
