Retinitis pigmentosa is commonly identified by the examination of the appearance of the retina using slit lamp biomicroscopy. Retinitis pigmentosa is caused by the gradual decline and loss of light-sensing cells called photoreceptors in the retina, which are vital for healthy eyesight. Visual acuity ranged between 20/20 (age: 35 and 50 years) and no light perception (70‐years old patient). 1 Retinitis pigmentosa with typical fundus appearance and functional loss was found in approximately 1 of 1000 elderly Chinese in northern China.
