Photopsias are unformed luminous spontaneous visual hallucinations, often described as flickering or wiggling lights, sometimes like a glare. Phosphenes are more intense and of shorter duration whereas migraine fortifications have a specific time course and succession of events. Recognition of this symptom is often poor, hence patients are wrongly investigated.
To describe the clinical presentation and electroretinographic characteristics of patients with photopsias.
4 patients were worked-up with clinical, psychophysical, angiographic and electroretinographic examinations.
Despite normal fundus and angiographic examinations, full-field electroretinogram was diagnostic in all cases. Retinal dysfunction involved either inner or outer retina. Paraneoplastic, and probable autoimmune/inflammatory retinopathies were found in our cases.
Photopsias are often secondary to sick retinal cells. In the presence of photopsias, investigations should be directed towards the retina and electroretinography is the gold standard. Recognition of the symptom should prevent useless and potentially harmful investigations for the patient.
光幻视是未成形的、自发的发光性视幻觉，常被描述为闪烁或晃动的光，有时类似眩光。光幻视更为强烈且持续时间较短，而偏头痛性视幻觉有特定的时间进程和一系列事件。对这种症状的认识往往不足，因此患者常接受错误的检查。
描述光幻视患者的临床表现和视网膜电图特征。
对4例患者进行了临床、心理物理学、血管造影和视网膜电图检查。
尽管眼底和血管造影检查正常，但全视野视网膜电图在所有病例中均具有诊断价值。视网膜功能障碍累及视网膜内层或外层。在我们的病例中发现了副肿瘤性以及可能的自身免疫/炎症性视网膜病变。
光幻视常继发于病变的视网膜细胞。出现光幻视时，检查应针对视网膜，视网膜电图是金标准。对该症状的认识应避免对患者进行无用且可能有害的检查。
