Solar retinopathy, resulting from solar eclipse exposure, poses risks to visual health. This study explores acute and chronic phase findings using clinical examinations and optical coherence tomography (OCT) and optical coherence tomography angiography (OCT-A) with a focus on longitudinal assessment.
Seven eyes with a history of unprotected solar eclipse exposure were included. Clinical examination, fundus photography, OCT, and OCT-A imaging were performed at initial assessment, as well as at one-month and six-month follow-up intervals. Data analysis included descriptive statistics.
The cases, exposed without protection, underwent assessments, revealing variable visual acuity, outer retinal layer, and Henle fiber layer changes during follow-up. Regression of hyperreflectivity within the outer retinal and Henle fiber layers was observed over time in all eyes, although persistent microdefects within the outer retinal layer were noted in specific cases. OCT-A imaging revealed a larger foveal avascular zone, which persisted over a six-month period in select cases. Additionally, affected eyes exhibited a decrease in superficial vascular density, with subsequent improvement noted during the six-month period.
Solar retinopathy can result in visual impairment, accompanied by alterations observed in the Henle fiber layer using OCT. Additionally, OCT-A findings indicate possible vascular involvement. This study underscores the significance of adopting protective measures during solar eclipses and emphasizes the value of employing longitudinal multimodal imaging techniques to comprehend the pathophysiology of the condition.
由日食暴露引起的太阳视网膜病变对视觉健康构成威胁。本研究通过临床检查以及光相干断层扫描（OCT）和光相干断层扫描血管造影（OCT-A），重点关注纵向评估，探讨了急性和慢性阶段的发现。
纳入 7 只曾有过未受保护的日食暴露史的眼睛。在初始评估以及一个月和六个月的随访间隔进行临床检查、眼底照相、OCT 和 OCT-A 成像。数据分析包括描述性统计。
这些未经保护而暴露的病例接受了评估，在随访过程中发现了视力、外视网膜层和 Henle 纤维层的变化。所有眼睛的外视网膜和 Henle 纤维层中的高反射性物质随时间逐渐消退，但在特定病例中仍存在外视网膜层的持续微缺陷。OCT-A 成像显示了更大的中央无血管区，在一些病例中持续了六个月。此外，受影响的眼睛表现出浅层血管密度下降，在六个月的随访期间有所改善。
太阳视网膜病变可导致视力障碍，并伴有 OCT 观察到的 Henle 纤维层改变。此外，OCT-A 的发现表明可能存在血管受累。本研究强调了在日食期间采取保护措施的重要性，并强调了采用纵向多模态成像技术来理解疾病病理生理学的价值。
