Reconstruction of Photoreceptor Outer Layers after Steroid Therapy in Solar Retinopathy

Abstract

Purpose. To report the clinical course of solar retinopathy after steroid therapy. Case Presentation. A 45-year-old male gazed at the sun and noticed bilateral central scotoma and decreased vision after the episode. After 7 weeks from onset, ophthalmic examinations were firstly performed. Decimal best corrected visual acuity (BCVA) was decreased to 0.8 and 0.7 in the right and left eyes. Funduscopy showed a tiny, yellowish spot in the fovea bilaterally. Corresponding to the lesion, optical coherence tomography (OCT) images showed an elevated and blurred ellipsoid zone and loss of the interdigitation zone. A posterior sub-Tenon triamcinolone injection in the right eye and oral prednisolone therapy were performed as a medication. BCVA was improved to 1.2 and 1.0 in the right and left eyes at 9 weeks after medication. OCT images showed ellipsoid zone was gradually improved bilaterally, which became nearly normal at 4 weeks in the right eye and at 21 weeks in the left eye. The loss of the interdigitation zone remained at 12 weeks in the right eye and at 21 weeks at the left eye. Conclusions. We described a case with solar retinopathy who exhibited anatomical recovery of the photoreceptor outer layers by steroid therapy, started after 7 weeks from onset.
