Management of Glaucoma with Dry Eye
Immediate Management
- The American Academy of Ophthalmology recommends restarting previously prescribed glaucoma medications as soon as possible to prevent further progression of glaucoma, with the addition of artificial tears for dry eye symptoms, and referring the patient for an urgent ophthalmology consultation 1, 2
- Add artificial tears for dry eye symptoms, with preservative-free formulations preferred to minimize irritation, and can be used 3-4 times daily or as needed 4
Administration Guidelines
- Instruct the patient to wait at least 5 minutes between different eye drops to prevent washout and ensure proper absorption, and demonstrate proper eye drop administration technique to ensure effective delivery 3
Rationale for Treatment
- Prostaglandin analogs like latanoprost provide the best IOP-lowering effect among all monotherapy regimens, reducing IOP by 22-39% over 1-12 months of treatment 1, 2
- The fixed combination of latanoprost and timolol has been shown to provide better IOP reduction than either agent alone 2
Pitfalls to Avoid
- Do not delay restarting glaucoma medications while waiting for ophthalmology consultation, as untreated glaucoma can lead to irreversible vision loss 1, 3
- Avoid aggressive eyelid massage for dry eye in patients with advanced glaucoma, as this may increase IOP 4
- Do not use corticosteroid eye drops for dry eye without ophthalmologist supervision, as they can increase IOP 4
