Changes in the Choroidal Thickness after Macular Buckling in
A Study was conducted to assess changes in the choroidal thickness (CT) after macular buckling in eyes with high myopia.

Highly myopic eyes that underwent macular buckling surgery were retrospectively analyzed. Data of swept-source optical coherence tomography scanning at baseline and at 1, 3, 6, 12, and 18 months after macular buckling were collected. Subfoveal CT and CT at 750 µm superior, inferior, nasal, and temporal to the fovea were measured.

--41 eyes were included in the final analysis. The subfoveal CT increased from 49.85 ± 31.23 micro-meter preoperatively to 75.74 ± 37.89 micro-meter 1 month after macular buckling, then decreased over time, coinciding with the trends of parafoveal CT, total choroidal area, vascular area, and stromal area.

--The subfoveal CT was restored to the preoperative level six months postoperatively and remained stable until the end of follow-up.

--The choroidal vascularity index increased at 1 and 3 months postoperatively.

Conclusively, In the early postoperative phase, the choroid thickened. The buckle implant's compression force may disrupt microcirculatory drainage and contribute to thickening. Over time, the choroid spontaneously restored to its preoperative state.
