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).
