Genetic Profile and Associated Characteristics of 150 Korean Patients with Retinitis Pigmentosa

Figure 3

Changes in the visual acuity and photoreceptor layers in the patients with retinitis pigmentosa carrying variants of four causative genes during the follow-up periods. Changes in the (a) visual acuity and (b) width of the photoreceptor layers during the follow-up periods. The trend lines were drawn based on the patients’ ages at the time of the examination and the symptom duration (defined as the period from the first symptoms to the age of the patient at the time of the examination). VA, visual acuity; LogMAR, logarithm of the minimum angle of resolution; IS/OS, photoreceptor inner segment/outer segment.
