[Central scotoma after viral prodrome].

CASE REPORT: A 29-year-old female patient presented with a unilateral deterioration of visual acuity, metamorphopsia and a paracentral scotoma. The patient had suffered from a viral rhinitis 1 week prior to the ophthalmological symptoms.

DIAGNOSTICS: Fundoscopy revealed parafoveal changes in the retinal pigment epithelium and spectral-domain optical coherence tomography (SD-OCT) disclosed corresponding hyperreflective, subretinal changes with disruption of Bruch's membrane and the outer limiting membrane. In the course of the disease there was a spontaneous regression of these changes. Visual acuity improved and the central scotoma resolved. The patient showed the typical history and clinical findings of unilateral acute idiopathic maculopathy.

CONCLUSION

The most probable explanation for the patient's symptoms is an immunologically triggered adverse reaction due to a previous viral rhinitis, with participation of the retina and retinal pigment epithelium. As a rule the disease has a spontaneous and favorable course.
