Fresnel prism correction for trauma-induced diplopia

Area of Science:

• Ophthalmology
• Vision Science
• Optical Devices

Background:

• Optic atrophy can lead to persistent visual field defects and double vision (diplopia).
• Managing double vision in patients with significant visual impairment presents a clinical challenge.

Observation:

• A patient with optic atrophy experienced constant double vision in their remaining visual field.
• Fresnel prisms were applied to the patient's spectacle lenses.

Findings:

• The application of Fresnel prisms successfully eliminated constant double vision.
• A minor reduction in visual acuity was observed due to the prisms.

Implications:

• Fresnel prisms offer a viable, non-invasive solution for managing diplopia in optic atrophy.
• The trade-off of minimal vision reduction for the elimination of double vision is considered beneficial.
