Treatment It is important to identify and treat any underlying medical conditions associated with NTG, such as anemias, arrhythmias, hypothyroidism, autoimmune diseases and migraine headaches. The Collaborative Normal Tension Glaucoma Study demonstrated that a 30 percent reduction in IOP can prevent progression of visual field loss in half of ...
Here, experts discuss the current approaches to treatment and weigh in on alternative perspectives to simply characterizing patients as having normal tension glaucoma within a subset of POAG. Unique Characteristics of NTG
General treatment. In general, management of normal tension glaucoma mirrors the medical and surgical management of the other forms of glaucoma and hinges on reduction of IOP from baseline. Identification of patients with clinical evidence of progression is important in the decision to initiate treatment for NTG.
Monitoring and treatment can reduce the risk of visual morbidity in most patients. This activity reviews the evaluation and management of normal-tension glaucoma and highlights the role of the interprofessional team in evaluating and treating patients with this condition.
In this article, we will explain what normal tension glaucoma is, the symptoms, risk factors, and treatments.
These include medication eye drops, SLT laser treatment, sustained-release medication implants, cataract surgery combined with MIGS (minimally invasive glaucoma surgery), or traditional surgery such as trabeculectomy. One of the treatment goals is to maintain a steady eye pressure.
Normal-tension glaucoma is treated in the same way as POAG by reducing the eye pressure using medications, laser treatment, and surgery. Blood flow to the optic nerve may play an important role in NTG but currently there is no treatment that can directly modify it.
Medications are still first-line treatment options for this condition. When medications are no longer sufficiently controlling IOP in the background of visual field worsening and progressive optic nerve injury, glaucoma filtering surgery is typically the next option.
Normal tension glaucoma (NTG) is an optic nerve neuropathy that presents with optic disc excavation, visual field loss in spite of intraocular pressure <21 mm Hg. Progressive visual field...
Current treatment. IOP remains the only proven modifiable risk factor for the treatment of glaucoma. However, it was not until the Collaborative Normal-Tension Glaucoma Study (CNTGS) that the significance of IOP reduction in the setting of statistically normal IOPs was confirmed.
