A recent post hoc analysis of the phase 3 OAKS and DERBY trials suggests that outer retinal tubulation (ORT) may be associated with a slower decline in visual acuity in patients with geographic atrophy (GA).
The study examined 300 eyes randomized to sham treatment, comparing best-corrected visual acuity outcomes over 24 months in eyes with and without ORT at baseline. Among the cohort, 32% of eyes exhibited ORT at the start of the study.
Eyes with ORT experienced, on average, a loss of 5.5 fewer Early Treatment Diabetic Retinopathy Study letters than those without ORT.
