Background: Ridges are delicately sculpted skin surface and their configural arrangements present on human fingers, toes, and soles. Aim: This study was aimed at determining the palmar ridge counts and palmar angles in acquired idiopathic blindness. Materials and Methods: The study had 72 subjects comprising 36 blind (14 females and 22 males) and 36 nonblind (18 females and 18 males). Palmar prints were obtained using print scanner (HP G3110 Photo Scanner). Results: The mean and standard deviation of the ridge counts for the total blind subjects: on the right hand, A–B was 26.02 ± 2.96, B–C was 27.04 ± 2.81, C–D was 33.16 ± 3.55; and on the left hand, A–B was 26.51 ± 2.38, B–C was 26.99 ± 2.89, and C–D was 33.20 ± 3.44. Considering the total ridge counts for the nonblind subjects on the right hand: A-B was 35.53 ± 1.99, B-C was 22.83 ± 1.87, and C-D was 41.20 ± 2.75; and on the left hand: A-B was 32.72 ± 2.54, B-C was 22.89 ± 2.24, and C-D was 41.30 ± 2.57. The palmar angles had the following values for the blind: on the right hand, ATD angle was 38.69° ± 3.65°, DAT angle was 60.11° ± 4.45°, and TDA angle was 81.19° ± 4.06°, while on the left hand: ATD angle was 38.47° ± 4.14°, DAT angle was 60.28° ± 4.49°, and TDA angle was 81.19° ± 4.50°. Conclusion: This study provides baseline information for researchers who will find it relevant in the course of their research with respect to palmar ridge counts and angles.
