Early macular thickening versus pseudophakic cystoid macular edema.

摘要

In their recent report, Buyukyildiz et al. consider the possible toxicity of 2.0 mg/0.1 mL intracameral cefuroxime leading to postoperative macular edema. It is important to distinguish between pseudophakic cystoid macular edema (CME) and acute macular thickening following cataract surgery. Cystoid macular edema is a well-known disease with no consensus about diagnostic criteria. Whereas some authors emphasize the clinical concept in terms of visual impairment caused by macular edema, others focus on the tomographic thickening or angiographic leakage. When and how can we talk about CME? In our opinion, the most updated definition is that provided by Kim et al., which includes the following: evidence of at least 40% increase in retinal thickness from baseline on optical coherence tomography (OCT) and an angiographic examination to confirm the presence of petaloid macular edema (CME), which may be associated with papillary leakage (Irvine-Gass syndrome).
