We describe a case of a 68-year-old man, referred by his optometrist with suspected low-tension glaucoma, who presented with advanced cupped optic discs and field of vision loss that were subsequently found to be due to a giant prolactinoma. [ncbi.nlm.nih.gov]

A detailed workup including neuroimaging may be indicated in patients with decreased central visual acuity ( 20/40), patients under 50 years of age, individuals with visual field defects that respect the vertical rather than horizontal midline, and those [glaucomatoday.com]

Nifedipine and acetazolamide treatment seemed to show no advantage over no-treatment in our patients. [ncbi.nlm.nih.gov]

Treatment[edit] Without treatment, NTG leads to progressive visual field loss and in the last consequence to blindness. [en.wikipedia.org]

No firm evidence was obtained to indicate that treatment of the low-tension glaucoma improved the prognosis of the ocular course. [ncbi.nlm.nih.gov]

• Prognosis and therapy : • According to Collaborative Normal-Tension Glaucoma Study (CNTGS) • Goal - to achieve an lOP that is as low as possible, without the development of complications. • Aggressive reduction in IOP by 30% to reduce progressive [slideshare.net]

Clinical data about the disease, such as the rate of glaucomatous visual field defect progression and risk factors for disease progression, might be helpful to clinicians to estimate prognosis and devise treatment regimens. [hindawi.com]

An additional consideration is that the presence of a disc hemorrhage indicates that the disease has a poorer prognosis; in this situation you may want to treat more aggressively. [reviewofophthalmology.com]

If vascular disease is important in the etiology of low-tension glaucoma, then it must be localized or vasospastic since this study does not support the concept of a generalized vascular etiology, either of an atheromatous or hyperviscous nature, for [ncbi.nlm.nih.gov]

Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. [icd10coded.com]

The etiology is poorly understood, but whatever it is, the level of IOP seems to determine whether the etiologic factors will lead to glaucomatous damage or not. [ijo.in]

Although estimates vary widely between studies, taken together, epidemiologic studies suggest that throughout the world, NTG represents perhaps 50% or more of all open-angle glaucoma. The more we look, the more we find, Dr. Park said. [eyeworld.org]

Management follows the same principle of other chronic glaucomas, to lower the IOP by a substantial amount, enough to prevent disabling visual loss. However, many NTG cases are non-progressive. [ncbi.nlm.nih.gov]

Can You Prevent It? Unfortunately, you can't prevent glaucoma. But blindness from the condition can often be prevented if it's diagnosed and treated early. So keep up with your regular eye exams done by an ophthalmologist. Pagination [webmd.com]

However, if a case seems typical and likely to progress, initiation of treatment would be prudent in order to prevent functional vision loss. [macfarlaneoptometrist.com.au]

Dips in blood pressure or a generally low blood pressure have to be prevented - which is a rather uncommon approach in modern medicine where high blood pressure is always seen as an immense clinical challenge, affecting large segments of the population [en.wikipedia.org]
