Diplopia is an uncommon finding in patients with subretinal neovascular membranes. We present two patients with binocular diplopia secondary to subretinal neovascular membranes and the foveal displacement syndrome. Subjective diplopia was not improved by prism therapy in either case. In one patient, diplopia was transiently relieved by removal of the choroidal neovascular membrane, but a subsequent subretinal hemorrhage resulted in severe visual loss. In the second patient, diplopia developed following laser therapy for a subretinal neovascular membrane. It is presumed that misalignment of the foveomacular receptor elements between the two eyes produced a central-peripheral fusional mechanism rivalry resulting in binocular diplopia. Ophthalmologists should be aware that a subretinal neovascular membrane may cause binocular diplopia and may mimic neuromuscular strabismus.
双眼复视在视网膜下新生血管膜患者中是一种不常见的表现。我们报告了两名因视网膜下新生血管膜和黄斑移位综合征继发双眼复视的患者。在这两例病例中，棱镜疗法均未改善主观复视。在一名患者中，去除脉络膜新生血管膜后复视暂时缓解，但随后的视网膜下出血导致严重视力丧失。在第二名患者中，视网膜下新生血管膜激光治疗后出现复视。据推测，双眼之间黄斑中心凹受体元件的排列不齐产生了中央 - 周边融合机制竞争，导致双眼复视。眼科医生应意识到视网膜下新生血管膜可能导致双眼复视，并可能模拟神经肌肉性斜视。
