| Summary: | The development of a full-thickness macular hole (FTMH) is a rare complication of intravitreal injections, and only a small subset of eyes with an FTMH has a spontaneous closure. We report a case of repeated FTMH formations and a spontaneous closure following an intravitreal injection of bevacizumab (IVB) for a central retinal vein occlusion (CRVO). A 39-year-old male patient presented with reduced vision in his right eye and was diagnosed with a CRVO. Two months later, neovascular glaucoma and macular edema (ME) developed and IVB was performed. After 2 weeks, optical coherence tomography revealed an improvement of the ME and the formation of an FTMH with a hyperreflective material in the FTMH. Two months later, there was a recurrence of the ME and a closure of the FTMH, but the hyperreflective material was still present in the retina. Then, another IVB and panretinal photocoagulation were performed. One month later, the ME had improved and the FTMH was closed, but the hyperreflective material was still present in the retina. After another 2 months, the ME recurred and a third IVB was performed. The ME improved without a recurrence of an FTMH. After that, there were no recurrences of the ME, but the FTMH recurred with the progression of a posterior vitreous detachment and development of an epiretinal membrane 1 year after the third IVB. We suggest that an FTMH be included as a complication of intravitreal injections, and it may close spontaneously during the course of the primary disease.
