Abstract Background Full-thickness idiopathic macular hole (IMH) usually causes serious visual deformities and visual acuity loss. Pseudophakic cystic macular edema, also known as Irvine-Gass syndrome, is another entity that causes visual disturbances, and occurs mainly after cataract extraction. We present a case report of a patient that was diagnosed with a full-thickness macular hole that spontaneously closed after the resolution of an Irvine-Gass syndrome, which occurred after an uneventful cataract extraction. Case presentation A 75 years-old female presented with the complaints of decreased visual acuity and color contrast sensitivity on both eyes (OU) and central visual field deformations on her left eye (LE). She was diagnosed with a full-thickness IMH on her LE, and cataract on OU. After an uneventful cataract extraction via phacoemulsification, she developed an Irvine-Gass syndrome at her LE, which was treated topically. The IMH closed spontaneously after the resolution of the Irvine-Gass syndrome, and the patient is being followed with no further complaints. Conclusion The exact mechanism for spontaneous closure of full-thickness idiopathic macular holes is still not completely understood. In this case, we hypothesize that the coalesced intraretinal cysts caused by the Irvine-Gass syndrome formed a bridge-like structure connecting the inner walls of the macular hole, thus connecting the remnants of the Muller cells which enabled the full recovery of the normal foveal structure.
