Clinical Scorecard: Occluder Prosthetic Soft Lens to Manage Diplopia
At a Glance
| Category | Detail |
|---|---|
| Condition | Diplopia secondary to adult strabismus associated with myasthenia gravis |
| Key Mechanisms | Use of computer-generated soft prosthetic occluder lens to block vision in one eye, relieving diplopia |
| Target Population | Adults with strabismus-induced diplopia seeking non-surgical management |
| Care Setting | Specialty contact lens fitting in optometric or ophthalmologic practice |
Key Highlights
- Soft prosthetic lenses traditionally used for cosmetic anterior segment disfigurement can also manage diplopia.
- Custom computer-generated prosthetic lenses provide precise iris coverage and pupil occlusion for diplopia relief.
- Low oxygen permeability (Dk) and pigment may increase hypoxia risk; monitoring is essential.
Guideline-Based Recommendations
Diagnosis
- Assess binocular vision and measure prism diopters to quantify strabismus.
- Perform anterior segment slit lamp examination to rule out ocular surface abnormalities.
- Measure horizontal visible iris diameter and photopic pupil size for lens fitting.
Management
- Fit computer-generated soft prosthetic occluder lens with appropriate iris coverage and pupil occlusion.
- Use hydrogen peroxide care system for nightly lens cleaning.
- Replace prosthetic lens annually to maintain comfort and function.
Monitoring & Follow-up
- Monitor for hypoxia-related complications due to low Dk and pigment-induced oxygen resistance.
- Regular follow-up to assess lens fit, ocular health, and patient comfort.
Risks
- Potential corneal hypoxia from low oxygen permeability of lens material and pigment.
- Possible discomfort or poor lens centration if prosthetic coverage is inadequate.
Patient & Prescribing Data
Adult patient with myasthenia gravis-induced strabismus and intermittent diplopia
Custom prosthetic soft lens with black backing and closed pupil provided immediate diplopia relief with good comfort and cosmetic appearance.
Clinical Best Practices
- Use precise iris and pupil measurements to customize prosthetic lens dimensions for optimal occlusion.
- Select lens materials balancing comfort and oxygen permeability; consider pigment impact on oxygen transmission.
- Educate patients on proper lens care with hydrogen peroxide systems and importance of annual lens replacement.
- Coordinate care with ophthalmologists and strabismus surgeons as appropriate.
