Solar maculopathy is a well described clinical entity that usually occurs in patients that have gazed directly the sun. In this report we describe the first two cases of solar maculopathy in individuals exposed to sunlight reflected from the screen of mobile devices in the absence of direct sun gaze.
Case 1. A 30-year-old Caucasic man presented with bilateral metamorphopsia, central scotoma and decreased visual acuity two days after being reading for four hours with his tablet computer in a terrace of a ski center.
CASE 2: A 20-year-old Caucasic woman was examined for bilateral decrease of visual acuity and central scotoma after being at the beach the day before and reading with her mobile phone for 3 hours. Both patients denied gazing directly to sunlight at any moment. In each case, exploration revealed fundus and OCT images compatible with the typical features of solar maculopathy. After 2 years of follow-up, in absence of any specific treatment, Case 1 had a complete resolution of the fundus alterations, while Case 2 still presented defects of the outer retinal layers. In both cases, an exposure to sunlight reflected from the screen of their mobile devices was documented in environments where solar radiation is thought to be augmented.
Sunlight reflection from a display screen needs to be considered as a possible risk factor for increased solar radiation and a subsequent risk of solar maculopathy.
太阳性黄斑病变是一种已被充分描述的临床实体，通常发生在直视太阳的患者中。在本报告中，我们描述了前两个在暴露于移动设备屏幕反射的阳光但无直接阳光注视下发生太阳性黄斑病变的病例。
病例 1. 一名 30 岁的白种男性在滑雪中心的露台上使用平板电脑阅读了四个小时后，出现了双侧视物变形、中心暗点和视力下降，两天后前来就诊。病例 2. 一名 20 岁的白种女性在海滩上呆了一天后，因双眼视力下降和中心暗点前来就诊，在此期间她用手机阅读了 3 个小时。两名患者均否认在任何时候直视过阳光。在每个病例中，检查均发现眼底和 OCT 图像与太阳性黄斑病变的典型特征相符。在 2 年的随访中，虽然未进行任何特定治疗，但病例 1 的眼底改变完全消退，而病例 2 的外层视网膜仍存在缺陷。在这两个病例中，均记录到他们的移动设备屏幕反射的阳光在被认为太阳辐射增强的环境中。
需要将来自显示屏幕的阳光反射视为增加太阳辐射和随后发生太阳性黄斑病变的潜在风险因素。
