Early Imaging of Macular Hole Closure: A Diagnostic Technique and Its Quality for Gas-Filled Eyes with Spectral Domain Optical Coherence Tomography
Background/Aims: This study was conducted to establish a reliable method to determine macular hole (MH) closure of gas-filled eyes. Method: 21 consecutive eyes with MH underwent vitrectomy with gas tamponade, and spectral domain optical coherence tomography (SD-OCT) was performed using our diagnostic technique. The quality of OCT images was rated as signal strength (SS) and evaluated by masked observers. Results: The quality to determine MH closure (SS ≥4) was sufficient in all eyes. In addition, SD-OCT images (SS ≥6) obtained from 16/21 eyes showed detailed retinal structures including the inner segment/outer segment line. The next day after ...
