Neuroretinitis classically presents with sudden vision loss, disc edema, and macular star formation. However, the classical triad may not always be seen, especially in the case of a pre-existing macular disorder. A thorough clinical examination may still clinch the appropriate diagnosis and prevent unwarranted treatment.
This study aimed to report a case of neuroretinitis in an adult woman with pre-existing type 2 macular telangiectasia where the classical pattern of exudation could not be seen.
A 48-year-old woman, type 2 diabetic and hypertensive, presented with sudden painless blurring of vision in the right eye for the past 1 week. Macula in both eyes had loss of transparency and intraretinal crystalline deposits and pigments. The right eye had hyperemic edematous disc with peripapillary retinal hemorrhages and hard exudates. Color vision was grossly abnormal, and a centrocecal scotoma was noted on visual field analysis in the right eye. After a normal systemic evaluation, a diagnosis of right eye neuroretinitis and coexistent bilateral type 2 macular telangiectasia (nonproliferative type) was made. Unilateral painless visual loss, severe dyschromatopsia, and peripapillary hard exudates pointed to the correct diagnosis of neuroretinitis. Observation was advised, and visual acuity improved spontaneously. The disc edema resolved with consequent optic atrophy.
Absence of the classical "macular star" appearance does not refute the diagnosis of neuroretinitis when pre-existing maculopathy is present.
神经视网膜炎的典型表现为突发性视力丧失、视盘水肿和黄斑星状形成。然而,经典三联征并不总是存在,尤其是在存在预先存在的黄斑病变的情况下。彻底的临床检查仍可明确适当的诊断并避免不必要的治疗。
本研究旨在报告一例成年女性伴有预先存在的 2 型黄斑毛细血管扩张症的神经视网膜炎病例,其中无法看到经典的渗出模式。
一名 48 岁女性,患有 2 型糖尿病和高血压,右眼出现无痛性视力模糊,持续 1 周。双眼黄斑区均有透明性丧失和视网膜内结晶状沉积物和色素。右眼视盘充血性水肿,伴有视盘周围视网膜出血和硬性渗出。色觉明显异常,右眼视野分析发现中心性暗点。在进行正常的系统评估后,诊断为右眼神经视网膜炎和双侧 2 型黄斑毛细血管扩张症(非增殖型)。单侧无痛性视力丧失、严重的色觉障碍和视盘周围硬性渗出提示正确诊断为神经视网膜炎。建议观察,视力自发改善。视盘水肿消退后出现视神经萎缩。
当存在预先存在的黄斑病变时,即使缺乏经典的“黄斑星”外观,也不能否定神经视网膜炎的诊断。
