To report two cases of diffuse unilateral subacute neuroretinitis (DUSN) from northern Iran and to present the sequential imaging.
Two patients with large subretinal nematodes were evaluated and managed in our clinic. Serial fundus photography and optical coherence tomography (OCT) imaging were used to document the course of the disease. Laser photocoagulation was administered to manage the patients.
The migration of the nematodes from subinternal limiting membrane space to subretinal space was documented in one case, coinciding with the onset of inflammatory and destructive processes. Both patients were successfully managed using laser photocoagulation alone. Follow-up examinations revealed partial recovery of the outer retinal layers and improvement in visual acuity. Nevertheless, some persistent atrophy in the retinal nerve fiber layer and ellipsoid layer was noted in the final examination.
We presented two cases of DUSN from northern Iran, with OCT documentation of transretinal migration in one case. Photocoagulation laser alone is an effective treatment modality in the early stage. The suboptimal final visual acuity appears to be linked to both inner and outer retinal layers' damage.
报告来自伊朗北部的两例弥漫性单侧亚急性神经视网膜炎（DUSN）病例，并展示其系列影像学表现。
对两名患有视网膜下大型线虫的患者在我们诊所进行评估和治疗。使用系列眼底照相和光学相干断层扫描（OCT）成像记录疾病进程。对患者实施激光光凝治疗。
在一例患者中记录到线虫从内界膜下间隙迁移至视网膜下间隙，这与炎症和破坏过程的开始相一致。两名患者仅通过激光光凝治疗均成功治愈。随访检查显示视网膜外层部分恢复且视力有所改善。然而，在最终检查中注意到视网膜神经纤维层和椭圆体层存在一些持续性萎缩。
我们报告了来自伊朗北部的两例DUSN病例，其中一例通过OCT记录到经视网膜迁移。单独使用光凝激光在早期是一种有效的治疗方式。最终视力欠佳似乎与视网膜内层和外层的损伤均有关。
