Objectives

Narrative objectives1

Retinitis pigmentosa is an inherited disease caused by degeneration of photoreceptor cells and retinal pigment epithelium.
There is no effective treatment, and cell therapy, artificial retina, and gene therapy are expected to be effective in the future.
Pallor of the optic nerve head is one of the characteristic findings in retinitis pigmentosa, and glial hyperintensities on the optic nerve head have been reported, but the cause of this phenomenon is not clearly understood.
We hypothesize that the cause of the pallor of the optic nerve head may be secondary to photoreceptor degeneration or reduced blood flow. We believe that simultaneous measurement of blood flow in addition to retinal structure will allow us to investigate the cause of the previously unexplained pallor of the optic nerve head in retinitis pigmentosa.
