lifestyle
2

Comprehensive Ophthalmologic Evaluation

Detailed eye examination including visual acuity testing, retinal assessment, and neurological evaluation to identify underlying causes of abnormal contrast sensitivity. Determines whether the abnormality is retinal, optic nerve, or cortical in origin.

3

Diagnostic Visual Evoked Potential Testing

Electrophysiological testing that measures the brain's response to visual stimuli, helping differentiate between retinal dysfunction and visual pathway abnormalities. Provides objective data when patient-reported symptoms may be unreliable.

Additional treatment options

Treat Underlying Condition

Pharmacological management of identified conditions such as optic neuritis, diabetic retinopathy, or vitamin deficiencies that may be causing the contrast sensitivity abnormality. Medication choice depends on specific diagnosis.

Environmental Modifications

Adjustments to lighting conditions, contrast enhancement in living and working environments, and use of assistive devices to compensate for reduced contrast sensitivity. Improves functional vision despite underlying abnormality.

lifestyle

Cataract Surgery Evaluation

Surgical consultation for patients where cataracts contribute to contrast sensitivity abnormalities. Phacoemulsification with intraocular lens placement may significantly improve visual function.
