Anatomical Narrow Angle Borderline Glaucoma C0154941
Narrow angle borderline glaucoma occurs when fluid drainage in the eye is restricted due to anatomical structure. It can lead to vision damage if untreated. Eye drops and procedures help manage pressure.

Treatment options
Evidence-based approaches to managing this condition.
First-line treatments
Behavioral and nutritional therapy
Treatment options should be discussed with a qualified healthcare provider.
YAG Laser Peripheral Iridotomy
A laser procedure that creates a small hole in the peripheral iris to improve fluid drainage and prevent angle closure. This is the primary preventive intervention for anatomical narrow-angle borderline glaucoma.
Additional treatment options
Topical Intraocular Pressure Medications
Lifelong use of eye drops including prostaglandin analogs, beta-blockers, or carbonic anhydrase inhibitors to control eye pressure. Multiple classes may be combined for optimal control.
medicationComprehensive Ophthalmologic Surveillance
Regular eye exams including gonioscopy, optical coherence tomography, and visual field testing to detect progression and assess treatment efficacy.
monitoringMedication Avoidance and Environmental Precautions
Avoid medications that can precipitate angle closure such as anticholinergics, sulfonamides, and certain antidepressants. Stay hydrated and avoid prolonged head-down positions.
lifestyleCataract Extraction
If lens opacification is contributing to angle narrowing, cataract surgery may widen the angle and reduce glaucoma risk. Combined procedures may be performed if needed.
