rtx1 study quantifies photoreceptor cell loss in Retinitis Pigmentosa patients

Ophthalmologists at Wenzhou Medical University Eye Hospital in China have used Imagine Eyes’ rtx1 adaptive optics retinal camera to investigate the impact of retinitis pigmentosa (RP) on cone photoreceptor cells.

Direct assessment of photoreceptors in RP patients by high-resolution imaging technologies is crucial for the future development of RP therapeutics.

Their study has resulted in an article recently published in Investigative Ophthalmology and Vision Science, which presents several new findings:

  • Significant differences in cone cell density were found not only between RP patients and healthy subjects, but also between patients at moderate and advanced stages of RP.
  • The impact of RP on cone density was best detectable in the parafoveal region of the retina, between 0.4 and 0.8 mm of eccentricity.
  • A significant correlation was found between visual acuity and cone density.
