Early imaging of macular hole closure: a diagnostic technique and its quality for gas-filled eyes with spectral domain optical coherence tomography.

摘要

This study was conducted to establish a reliable method to determine macular hole (MH) closure of gas-filled eyes.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.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 surgery, MH closure was confirmed in 12/21 eyes, and residual MH was observed in 9/21 eyes. Among these 9 eyes, 7 eyes were closed within 2 weeks.The present method provided clear SD-OCT images from gas-filled eyes, which is not only essential for the diagnosis of MH closure but also for establishing proper protocols and for studying the pathology of gas-filled eyes.
