• Vitreous fluorophotometry was used to assess the functional integrity of the blood-retinal barrier in four female carriers of X-linked recessive retinitis pigmentosa. Abnormal findings in all four carriers suggest that a defect in the blood-retinal barrier, detectable by vitreous fluorophotometry, is a sensitive means by which carriers can be identified.
