Objective: To present a patient with Irvine-Gass syndrome in the right eye complicated with a macular hole (MH) in the same eye and possible associations between these two entities. Case report: A 72-year-old male with a history of uneventful bilateral cataract surgery was followed-up with biomicroscopy and optical coherence tomography (OCT). Four weeks after cataract surgery oculus dexter (OD), there was progressive visual deterioration (best corrected visual acuity [BCVA]: 0.5). OCT disclosed cystoid ME. A parabulbar triamcinolone injection, dexamethasone 0.1% and ketorolac 0.4% eye drops, both 4 times per day OD were administered. Six weeks later (BCVA OD: 0.2), OCT revealed cystoid ME and full-thickness MH. Conclusion: ME secondary to diabetes or central retinal vein occlusion may lead to MH by inducing focal vitreomacular traction and by triggering inflammatory mechanisms which facilitate a marked thinning of the fovea. MH may occur even in cases of pseudophakic ME, representing a rare complication of Irvine-Gass syndrome. Keywords: Irvine-Gass syndrome, macular hole, macular edema
