Anatomical Changes of Full-Thickness Macular Hole Documented by Microscope-Integrated Spectral-Domain Optical Coherence Tomography.

BACKGROUND AND OBJECTIVE

To evaluate anatomical changes of idiopathic macular hole (MH) after internal limiting membrane removal and after passive suction at the hole's borders using microscope-integrated intraoperative optical coherence tomography (iOCT).

PATIENTS AND METHODS

Five eyes of five subjects with full-thickness idiopathic MH underwent phacoemulsification, intraocular lens implantation, pars plana vitrectomy, and internal limiting membrane (ILM) removal. iOCT was performed after ILM removal and after passive suction at the hole's borders.

RESULTS

iOCT showed decreased MH diameter after ILM removal in all cases. Passive suction achieved complete apposition of borders. All cases presented successful postsurgical closure.

CONCLUSIONS

iOCT provides anatomical information during MH surgery that may impact surgical decision-making by allowing a real-time evaluation of structures. iOCT with preservative-free triamcinolone acetonide enhanced ILM visualization. Its use is superior to iOCT alone for the identification of vitreomacular interface structures. [Ophthalmic Surg Lasers Imaging Retina. 2018;49:e105-e111.].
