We reported a case of achromatic retinitis pigmentosa admitted to the hospital in January 2019. The patient was diagnosed by fundus fluorescein angiography because of poor vision, and no abnormality was found by routine ophthalmological examination and general examination. After fundus fluorescein angiography (FFA), a rare non-pigmented retinitis pigmentosa was finally diagnosed, which prevented misdiagnosis and missed diagnosis of the disease. For the patients without typical triad of retinitis pigmentosa, we should pay attention to missing the diagnosis in clinical practice. FFA can make a definite diagnosis of retinitis pigmentosa.
