Macular Hole Caused by Retained Subfoveal Perfluorocarbon that Subsequently Closed After Its Spontaneous Resolution: A Case Report

INTRODUCTION: To prevent local reduction in retinal function caused by retained subretinal perfluorocarbon liquid (PFCL), it has been noted that removal of PFCL under the fovea should be considered, with a vitrectomy selected for such removal. CASE REPORT: A vitrectomy was performed for traumatic retinal detachment during which PFCL was temporarily used as an intraocular tamponade for retina flattening. Following surgery, subfoveal PFCL was retained beneath the retina. Two months later, a macular hole developed and visual acuity decreased to 20/100, for which a vitrectomy was planned as treatment. However, the macular hole spontaneously closed and visual acuity eventually recovered to 20/25. CONCLUSION: Our findings indicate that PFCL retained underneath the retina in the macular region can cause a macular hole, though spontaneous discharge may subsequently occur, leading to resolution.
