The most well-studied and widely prescribed fixed-combination drug for open-angle glaucoma is latanoprost/timolol. Its significant hypotensive effect is especially important in challenging cases, among which are patients with normal-tension glaucoma. With long life expectancy and the constant need for treatment, requirements are high for both the effectiveness of the drug and its tolerability. This paper presents a follow-up of 7 patients with normal-tension glaucoma who have been using the fixed combination of latanoprost/timolol for 10 years. All patients showed very good tolerability to the drug and their quality of life was preserved. A moderate rate of disease progression according to static perimetry was noted in one case. A mild degree of dry eye syndrome according to the OSDI questionnaire and an objective assessment of the state of the ocular surface was observed in one patient. The latanoprost/timolol fixed combination is a well-tolerated, highly effective and safe long-term treatment choice for normal-tension glaucoma.

Background: Endothelin is a potent vasoconstrictor and contributes to the regulation of vascular perfusion. Aberrant endothelin-1 (ET-1) levels in aqueous humor have been reported across a variety of vascular diseases of the eye, including glaucoma. These findings suggest that dysregulation of ET-1 production may contribute to glaucoma pathophysiology.

Objectives: To report on the incidence of optic nerve kinking in a series of patients diagnosed with normal-tension glaucoma (NTG) compared to an age- and gender matched control group without known optic nerve diseases.
Subjects And Methods: All patients with NTG who underwent imaging (computed tomography cysternography (CTC) or magnetic resonance imaging (MRI)) of the orbits and cranium between 2012 and 2022 were included, totalling 57 patients (27 females and 30 males; 57 eyes; mean age 69 ± 10 years). 57 age- and gender matched subjects without known optic nerve diseases who underwent MRI of the orbits and cranium served as controls.

Purpose: To investigate the relationship between nocturnal blood pressure (BP) dip and parapapillary choroidal vessel density (pCVD) in patients with normal-tension glaucoma (NTG).
Methods: This study analyzed 267 eyes of 267 untreated NTG patients who underwent 24-hour (h) intraocular pressure (IOP) and ambulatory BP monitoring in the habitual position. Patients were classified into 3 groups [non-dippers (nocturnal BP dip < 10%), dippers (nocturnal BP dip between 10% and 20%, and over-dippers (nocturnal BP dip > 20%)], and pCVDs were measured by using optical coherence tomography angiography (OCTA) images.

Background: Cerebral autoregulation is a robust regulatory mechanism that stabilizes cerebral blood flow in response to reduced blood pressure, thereby preventing cerebral ischaemia. Scientists have long believed that cerebral autoregulation also stabilizes cerebral blood flow against increases in intracranial pressure, which is another component that determines cerebral perfusion pressure. However, this idea was inconsistent with the complex pathogenesis of normal pressure hydrocephalus, which includes components of chronic cerebral ischaemia due to mild increases in intracranial pressure.

Objective: To report an unusual manifestation of normal tension glaucoma(NTG) in a young female as presenting feature of Takayasu arteritis (TA).
Methods: We present a case of a 24-year-old woman who was initially diagnosed with NTG, with characteristic optic disc and retinal nerve fiber layer (RNFL) changes, and corresponding visual field defects. Further evaluation with CT angiography revealed that the patient had newly diagnosed TA.
