Enlargement of the blind spot without optic disc edema has been reported in patients with no other ocular findings (acute idiopathic blind spot enlargement) and in patients with multiple evanescent white dot syndrome. We describe three patients with multifocal choroiditis who developed acute symptomatic enlargement of the blind spot. All three patients were young women in excellent health. During the course of the blind spot enlargement, the appearance of the optic nerve remained normal. We demonstrate that acute enlargement of the blind spot without disc edema occurs in patients with multifocal choroiditis. This enlargement is likely due to peripapillary retinal dysfunction. We speculate on the association of multifocal choroiditis with acute idiopathic blind spot enlargement and multiple evanescent white dot syndrome.
据报道，在没有其他眼部表现的患者（急性特发性盲点扩大）以及多灶性一过性白点综合征患者中，存在盲点扩大但无视盘水肿的情况。我们描述了3例多灶性脉络膜炎患者出现急性症状性盲点扩大。所有3例患者均为健康状况良好的年轻女性。在盲点扩大过程中，视神经外观保持正常。我们证明，多灶性脉络膜炎患者会出现无视盘水肿的急性盲点扩大。这种扩大可能是由于视乳头周围视网膜功能障碍所致。我们推测多灶性脉络膜炎与急性特发性盲点扩大和多灶性一过性白点综合征之间的关联。
