Clinical Scorecard: Dry Eye: Supporting Patients
At a Glance
| Category | Detail |
|---|---|
| Condition | Dry Eye Disease |
| Key Mechanisms | Corneal nerve damage due to repeated anti-VEGF injections leading to neurotrophic keratitis. |
| Target Population | Patients receiving multiple intravitreal anti-VEGF injections for AMD and DME. |
| Care Setting | Ophthalmology clinics and practices. |
Key Highlights
- Significant reduction in corneal nerve fiber density and sensitivity after third anti-VEGF injection.
- Increased risk of neurotrophic keratitis in patients with diabetes post-injection.
- Osmoprotective preservative-free artificial tears recommended for ocular surface protection.
- Omega-3 supplementation shown to improve corneal nerve health and dry eye symptoms.
- Curcumin may enhance corneal wound healing, though human studies are limited.
Guideline-Based Recommendations
Diagnosis
- Screen for neurotrophic keratitis in AMD and DME patients.
- Use corneal sensation testing methods such as Cochet-Bonnet aesthesiometer.
Management
- Prescribe Omega-3 polyunsaturated fatty acids, preservative-free artificial tears, and other supportive therapies.
Monitoring & Follow-up
- Monitor for neurotrophic keratitis, especially in patients with extensive panretinal photocoagulation history.
Risks
- Increased risk of nonhealing epithelial defects due to corneal nerve damage.
Patient & Prescribing Data
Patients with AMD and DME undergoing repeated anti-VEGF injections.
Supportive therapies including Omega-3 supplementation and preservative-free artificial tears are beneficial.
Clinical Best Practices
- Utilize a comprehensive approach to manage dry eye symptoms in patients receiving anti-VEGF injections.
- Educate patients on the importance of ocular surface care post-injection.
