Purpose:
To present a report of longitudinal changes in radial peripapillary capillaries (RPC) and changes in retinal full thickness (RFT) and peripapillary retinal nerve fiber layer (RNFL) in a patient with Leber hereditary optic neuropathy (LHON).
Observations:
A 42-year-old man presented with acute- and presymptomatic-stage LHON in the left (OS) and right (OD) eyes, respectively, at the initial visit. Onset of LHON in the OD was observed 2 months after the initial visit. Once the temporal RNFL started to decrease in thickness, the areas of temporal RPC defects and RFT thinning gradually increased, indicating that these factors might be correlated.
Conclusions And Importance:
Optical coherence tomography angiography showed LHON from the presymptomatic stage. The results indicate that temporal RPC defects and RFT thinning start to spread once the pseudoedema begins to resolve.

Assessment of radial pulse
The radial pulse, located at the wrist, is often the preferred site for assessing peripheral pulse because of its accessibility and dependability. The process of determining the radial pulse involves several steps:
