Restsehprobleme

Restsehprobleme, literally “rest vision problems” in German, describe persistent or residual visual disturbances that remain after a primary ocular condition has been treated or resolved, or that persist as part of a chronic visual impairment. The term is used in ophthalmology and vision rehabilitation to distinguish reversible symptoms from lasting deficits.

Causes include residual refractive error after cataract or refractive surgery; macular diseases such as age-related macular degeneration; glaucoma or optic neuropathies; retinal scars; cortical visual impairment; persistent amblyopia; and fluctuations due to dry eye or tear-film instability.

Common symptoms are decreased visual acuity, blurred or distorted vision, glare and halos, reduced contrast sensitivity, metamorphopsia, and partial or complete field loss. Symptoms may be stable or fluctuate with lighting, fatigue, or ocular surface status.

Diagnosis relies on a complete eye examination: measurement of best-corrected visual acuity, refraction, dilated fundus examination, optical coherence tomography (OCT), perimetry, and sometimes retinal imaging or electrophysiology to identify underlying causes.

Management depends on the underlying etiology and may include refractive correction (glasses or contact lenses), low-vision aids, visual rehabilitation, prism or field-expanding lenses for field loss, management of ocular surface disease, and treatment of retinal or optic nerve disorders. Psychological support and occupational training may help adapt to residual deficits.

Prognosis varies with cause; some residual deficits remain despite treatment, whereas timely intervention can improve function. Ongoing research focuses on neuro-visual rehabilitation and assistive technologies.
