Glaucoma involves a characteristic optic neuropathy, often with elevated intraocular pressure. Before 1850, poor vision with a normal eye appearance, as occurs in primary open-angle glaucoma, was termed amaurosis, gutta serena, or black cataract. Few observers noted palpable hardness of the eye in amaurosis. On the other hand, angle-closure glaucoma can produce a green or gray pupil, and therefore was called, variously, glaucoma (derived from the Greek for glaucous, a nonspecific term connoting blue, green, or light gray) and viriditate oculi. Angle closure, with palpable hardness of the eye, mydriasis, and anterior prominence of the lens, was described in greater detail in the 18th and 19th centuries. The introduction of the ophthalmoscope in 1850 permitted the visualization of the excavated optic neuropathy in eyes with a normal or with a dilated greenish-gray pupil. Physicians developed a better appreciation of the role of intraocular pressure in both conditions, which became subsumed under the rubric “glaucoma”.

Background/Aim. Glaucoma is a progressive optic neuropathy characterized by damage of the retinal ganglion cells and their axons and glial cells. The aim of this study was to evaluate the differences and connections between changes in the visual field and the thickness of the peripapillary retinal nerve fiber layer (RNFL), using optical coherence tomography (OCT) in patients with primary open-angle glaucoma with normal and elevated intraocular pressure (IOP). Methods. This prospective study included 38 patients (38 eyes) with primary open-angle glaucoma with normal intraocular pressure (NTG) and 50 patients (50 eyes) with primary open-angle glaucoma with elevated intraocular pressure (HTG), paired by the same degree of structural glaucomatous changes in the optic nerve head and by age. OCT protocols ?fast RNFL thickness? and ?fast optic disc? were used for testing. The patients? age, gender, best corrected visual acuity (BCVA), IOP, stereometric and functional parameters were compared. Results. The average age of the examined population was 65.49 ? 9.36 (range 44-83) years. There was no statistically significant difference by age and by gender between the two study groups (p = 0.795 and p = 0.807, respectively). BCVA was higher in patients with NTG but there was no statistically significant difference compared to HTG patients (p = 0.160). IOP was statistically significantly higher in patients with HTG compared to NTG patients (17.40 ? 2.77 mmHg vs 14.95 ? 3.01 mmHg, p = 0.009). The cup/disc (C/D) (p = 0.258), mean deviation (MD) (p = 0.477), corrected patern standard deviation (CPSD) (p = 0.943), disk area (p = 0.515), rim area (p = 0.294), rim volume (p = 0.118), C/D area R (p = 0.103), RNFL Average (p = 0.632), RNFL Superior (p = 0.283) and RNFL Inferior (p = 0.488) were not statistically significantly different between the groups. Conclusion. OCT measurements of the RNFL thickness provide clinically significant information in monitoring of glaucomatous changes. There are no differences in the patterns of RNFL defects per sectors and quadrants between NTG and HTG, measured by OCT.

Introduction. An altered perfusion of the optic nerve head has been proposed as a pathogenic factor in glaucoma. Objective. To evaluate changes of haemodynamic parameters in the retrobulbar arterial circulation after a decrease of elevated intraocular pressure (IOP) in patients with primary open angle glaucoma (POAG). Methods. Twenty-six patients were examined, 14 men and 12 women, 21 up to 50 years old and 5 below, all with previously diagnosed and treated POAG, and all examined at the Eye Clinic, Clinical Centre of Serbia. IOP was measured both with a Goldmann aplanation tonometer and dynamic contour tonometer. Central corneal thickness was measured with ultrasound pachymeter. Imaging of the retrobulbar arterial circulation by colour Doppler was performed at the Neurology Clinic, Clinical Centre of Serbia. It involved measuring of haemodynamic parameters of the ophthalmic artery, central retinal artery, and posterior ciliary arteries. Peak systolic velocity (PSV) and end-diastolic velocity (EDV) were measured, and resistive index (RI) and pulsatility index (PI) were calculated. Results. Haemodynamic arterial parameters PSV and EDV in the ophthalmic and central retinal artery after decrease of IOP were lower, while RI and PI were higher. In the posterior ciliary arteries PSV, EDV and PI were lower, and RI was higher. Conclusion. Changes of the retrobulbar arterial circulation after elevated IOP in POAG patients are important for approach and treatment, while the role of vascular factors in the supplement of the optic disc neuroretinal rim could be a key for progression backlash of glaucoma and the radix of neuroprotection.

Introduction. Ocular blood flow (OBF) disturbances could be involved both in the pathogenesis and in progression of glaucomatous damage. Objective. The aim of the study was to compare the retrobulbar hemodynamic parameters in the ophthalmic artery (OA), central retinal artery (CRA) and short posterior cilliary arteries (SPCA) after decreasing the elevated intraocular pressure (IOP) in primary open-angle glaucoma (POAG) patients by using color Doppler imaging (CDI). Methods. We examined 60 patients (21 male and 39 female) with diagnosed and treated POAG. Thirtynine patients had increased IOP (>25 mm Hg). Peak-systolic velocity (PSV), end-diastolic velocity (EDV), Pourcelot resistance index (RI), and pulsatility index (PI) were assessed in the OA, CRA, and SPCA. IOP was measured both with the Goldmann Applanation tonometer (GAT) and with the Dynamic Contour tonometer (DCT), three times respectively. Ocular pulse amplitude (OPA) was measured using DCT. Results. The retrobulbar parameters between the baseline and after IOP reduction showed no difference in measurements. After Bonferroni correction (p?0.0056, alpha/9) statistical significance was recorded only in the following retrobulbar hemodynamic parameters; DCT (29.8?6.2 vs. 15.5?5.0), GAT (33.8?9.0 vs. 15.0?6.6) and OPA measurements (4.3?1.0 vs. 3.0?1.6), as compared to the baseline. There was no correlation between the changes in IOP measured with either DCT or GAT and changes in the hemodynamic parameters (p>0.05 for all). Pearson correlation coefficient (95% CI) showed very good correlation for IOP measurements between DCT and GAT: at baseline 0.83 (0.71 to 0.90) and at the end 0.71 (0.55 to 0.83); p<0.0001 for both measurements, but without any difference between them (p>0.05). Conclusion. There was a lack of correlation between the changes in IOP measured with either DCT or GAT and the changes in the hemodynamic parameters.

Introduction. An altered perfusion of the optic nerve head has been proposed as a pathogenic factor of glaucoma. Objective. The aim of this study was to evaluate the changes of the hemodynamic parameters in the retrobulbar arterial circulation after decrease of the elevated intraocular pressure (IOP) in women and men with primary open angle glaucoma. Methods. The study included 60 patients (33 males and 27 females) older than 50 years, with diagnosed and treated primary open angle glaucoma (77 eyes of 39 patients had increased IOP, >25 mm Hg). They were examined at the Clinic of Eye Diseases (complete ophthalmologic exam) and Clinic of Neurology, Clinical Center of Serbia, Belgrade, from December 2009 to December 2010. Imaging of hemodynamic parameters of three retrobulbar arterial vessels: ophthalmic, central retinal and posterior ciliary arteries with color Doppler was performed. Results. Among women, hemodynamic arterial parameter of the peak-systolic velocity was increased in the central retinal artery and decreased in the ophthalmic artery and posterior ciliary arteries; end- diastolic velocity was increased in all three retrobulbar vascular levels; Pourcelot resistivity index was increased, but pulsatility index was decreased in all three vessels. Among men, peak-systolic velocity, end-diastolic velocity and pulsatility index were decreased in all three vessels; resistivity index was increased in the ophthalmic artery, but decreased in the central retinal artery and posterior ciliary arteries. There was a significant change of the ophthalmic artery pulsatility index in women, and the end-diastolic velocity of the ophthalmic artery in men. Conclusion. There was a difference of the retrobulbar arterial circulation between women and men with primary open angle glaucoma after decrease of the elevated intraocular pressure. The role of vascular factors in the supply of the optic disc neuroretinal rim is important.

Introduction. Glaucoma is one of the most significant eye diseases. It is often diagnosed, not always amenable to therapy, and can lead to a complete loss of visual functions. In recent years, the method of osteopathic correction has become widespread as one of the effective methods of treatment and rehabilitation of patients with pathologies of various body systems. In the pathogenesis of glaucoma, it is customary to distinguish a dystrophic concept, which considers primary open-angle glaucoma as a result of dystrophic changes in the connective tissue, as well as in the endothelial lining of the trabeculae and Schlemm′s canal, especially destructive changes in mitochondria and the alteration of their functional activity. A vascular concept is also distinguished. According to this concept, the central link in the pathogenesis of glaucoma is circulatory disorder in the ciliary vessels, ocular artery, and major vessels of the head and neck, it can be assumed that osteopathic correction in the treatment of patients with open-angle glaucoma will be pathogenetically substantiated and will have a positive effect on intraocular pressure and trophicity of the optic nerve. The goal of research — to study the influence of in osteopathic correction on the nature of unoperated glaucoma (stage IIA) and to substantiate the possibility of using osteopathic correction in the complex treatment of patients with this pathology.Materials and methods. A prospective controlled randomized study was conducted at 52 city polyclinics, branch 3, Moscow, from January 2018 to January 2019. 40 patients (70 eyes) aged 50 to 75 years with primary open-angle glaucoma IIA stage were examined. At this stage of the disease, patients most often seek medical care and the issue of conservative management is primarily considered. All patients were divided into two groups of 20 people: the main group and the control group. The treatment in the main group included hypotensive drug therapy and osteopathic correction. Patients of the control group received only drug therapy. All patients underwent ophthalmic (visometry, tonometry, perimetry) and osteopathic examination twice: before the treatment and after 3 months.Results. For patients with primary open-angle IIA non-operated glaucoma, regional (most often regions of the head, neck, dura mater) and local (abdominal diaphragm, iliac bones, hip and knee joints) somatic dysfunctions were the most typical. In the main group a statistically significant decrease in the frequency and severity of dysfunctions at all levels was stated. Also, in patients receiving osteopathic correction, a significant decrease in the level of intraocular pressure and perimetric indices was noted. In patients of the control group, no reliable changes in these indicators were obtained.Conclusion. The results obtained indicate that osteopathic correction is clinically effective in the complex treatment of patients with primary open-angle II A glaucoma.
