Many developmental defects can simulate the optic disc (optic disc pseudodoubling). True optic disc duplication with 2 independent retinal vasculatures is rare. Associated optic nerve duplication is rarer still and seen in lower vertebrates. We report a rare case of unilateral double optic discs with a single optic nerve in the left eye of a 41-year-old man, otherwise asymptomatic in the affected eye.
许多发育缺陷都可模拟视盘（视盘假性双生）。真正的视盘重复，伴有 2 条独立的视网膜血管系统，较为罕见。伴有视神经重复更为罕见，只见于低等脊椎动物。我们报道 1 例 41 岁男性左眼单侧性双视盘，伴有单根视神经，患眼无症状。
