Photoreceptor cells quantified in RP with and without CME

Recently published in PLOS ONE, a clinical study at the Kobe Eye Center reports quantitative assessment of cone photoreceptor cells in retinitis pigmentosa patients with and without cystoid macular edema (CME) using a rtx1 AO camera. Parafoveal cones were analyzed in locations where OCT did not show CME.

“Although the length of the EZ/IZ, which reflects the progression of RP, did not significantly differ between the groups, a history of CME was associated with photoreceptor loss.”
