Abstract
BACKGROUND Peripheral arterial disease (PAD) and diabetes are the major causes of lower extremity amputations (LEAs) worldwide. Morbidity and mortality in patients with LEAs are high with an associated significant burden on the global health system. The aim of this article is to report the overall morbidity and mortality rates after major and minor LEAs from the Serbian Vascular Registry (SerbVasc), with an analysis of predictive factors that influenced adverse outcomes. MATERIALS AND METHODS SerbVasc was created in 2019 as a part of the Vascunet collaboration that is aiming to include all vascular procedures from 21 hospitals in Serbia. Prevalence of diabetes among patients with LEAs, previous revascularization procedures, the degree and the type of foot infection and tissue loss, and overall morbidity and mortality rates were analyzed, with a special reference to mortality predictors. RESULTS In the period from January 2020 to December 2022, data on 702 patients with LEAs were extracted from the SerbVasc registry, mean age of 69.06±10.63 years. Major LEAs were performed in 59%, while minor LEAs in 41% of patients. Diabetes was seen in 65.1% of the patients, with 44% of them being on insulin therapy. Before LEA, only 20.3% of patients had previous peripheral revascularization. Soft tissue infection, irreversible acute ischemia, and Fontaine III and IV grade ischemia were the most common causes of above-the-knee amputations while diabetic foot was the most common cause of transphalangeal and toe amputations. The infection rate was 3.7%, the re-amputation rate was 5.7%, and the overall mortality rate was 6.9%, with intrahospital mortality in patients with above-the-knee amputation of 11.1%. The most significant intrahospital mortality predictors were age >65 years (p<0.001), chronic kidney disease (CKD) (p<0.001), ischemic heart disease (IHD) (p=0.001), previous myocardial revascularization (p=0.017), emergency type of admission (p<0.001), not using aspirin (p=0.041), using previous anticoagulation therapy (p=0.003), and postoperative complications (p<0.001). CONCLUSIONS The main predictors of increased mortality after LEAs from the SerbVasc registry are age >65 years, CKD, IHD, previous myocardial revascularization, emergency type of admission, not using aspirin, using previous anticoagulation therapy, and postoperative complications. Taking into account high mortality rates after LEAs and a small proportion of previous peripheral revascularization, the work should be done on early diagnosis and timely treatment of PAD hopefully leading to decreased number of LEAs and overall mortality. CLINICAL IMPACT Mortality after lower limb amputation from the SerbVasc register is high. A small number of previously revascularized patients is of particular clinical importance, bearing in mind that the main reasons for above-the-knee amputations were irreversible ischemia, Fontaine III and Fontaine IV grade ischemia. Lack of diagnostics procedures and late recognition of patients with PAD, led to subsequent threating limb ischemia and increased amputation rates. The work should be done on early diagnosis and timely treatment of PAD in Serbia, hopefully leading to an increased number of PAD procedures, decreased number of LEAs, and lower overall mortality.

Abstract
Objective: Swallowing difficulties cause patients with amyotrophic lateral sclerosis (ALS) to crush oral medications, falling outside the labeling instructions and entailing some risks. To date, there is no evidence about consequences of crushing riluzole tablets in a home setting. This simulation experiment evaluated the loss of powder and active principle ingredient (API) mimicking the home setting with two alternative crushing methods (A and B). Methods: The tests were carried out by 15 volunteers without experience in the preparation of medication. Each volunteer manually crushed 5 tablets with a meat tenderizer (method A) or two spoons pressed against each other (method B). Riluzole was weighed before (W1) and after crushing (W2). Then, a subsample of crushed tablets was analyzed by HPLC to measure API content. The loss of powder was calculated as a percentage of the intact tablet weight, and the loss of API as a percentage of the labeled API content. Results: The quantitative analysis showed a mean percentage loss of 6.27% corresponding to a mean (SD) loss of powder of 13(±13) mg. The API loss was directly related to the powder loss: overall the mean percentage of API loss was 8.53% (corresponding to a mean API loss of 4.27 ± 4.50 mg). The difference in powder and API loss was highly statistically significant. Conclusion: Crushing riluzole tablets in a simulated home setting determined a significant loss of powder and API. These results support neurologists to evaluate formulations that minimize the need to alter the product and can improve ALS patient journey.

Abstract
Purpose The aim of this study was to use non-invasive impedance cardiography (ICG) to determine the hemodynamic status of patients with grade 1 and grade 2 hypertension in relation to gender and age. Patients and Methods We analyse prospectively collected data of 158 patients with grade 1 or grade 2 arterial hypertension. Patients were grouped according to age: 1) <50 years and 2) ≥50 years. Hemodynamic status of patients was assessed by using non-invasive ICG. For the purpose of this study two hemodynamic parameters were used: a) systemic vascular resistance index (SVRI) and b) left cardiac work index (LCWI). The primary endpoint was the hemodynamic status of patients. The secondary endpoint was hypertension-mediated organ damage. Results Increased SVRI was assessed in 80% of patients, more common in the ≥50 years group than in the <50 years group (88.5% vs 64.8%; p < 0.01). The occurrence of increased systemic vascular resistance correlates hierarchically with increasing age. Elevated LCWI (hypervolemia and/or hyperinotropy) was present in 63% of patients, more often in males than females (70.3% vs 57.1%; p < 0.05) as well in those <50 years than in older patients (70.4% vs 59.6%; p < 0.05). Patients with diabetes were less likely to have hypervolemia/hyperinotropy than those without diabetes (46.7% vs 67.2%; p < 0.01). Hypervolemia/hyperinotropy (46.7%) and hypovolemia/hypoinotropy (43.3%) were present in a similar percentage of diabetic patients. Left ventricular hypertrophy was found in 30 patients (19%). Patients with left ventricular hypertrophy were more commonly male (66.7% vs 42.2%; p = 0.016) and had increased systemic vascular resistance (96.7% vs 77.3%; p = 0.015) compared to the patients without left ventricular hypertrophy. Hypertensive retinopathy grade III was found in 14 patients (8.9%). Elevated daytime systolic pressure, diabetes and increased age are independent predictors of grade III hypertensive retinopathy. Patients with reduced renal function had higher mean systolic blood pressure (p < 0.05), were more commonly male (p < 0.01) and older (p < 0.01) than those without reduced renal function. Conclusion Although there are certain correlations between hemodynamic disorders and age and gender, specific hemodynamic status of an individual patient with hypertension cannot reliably be predicted on the basis of age and gender. The measurement of hemodynamic parameters by ICG can guide the clinician to select appropriate antihypertensive therapy to the patients’ hemodynamic pathophysiologic condition.

Abstract
Background: There is increasing evidence of gender differences in the epidemiology and clinical manifestation of both motor and non-motor symptoms of Parkinson's disease (PD). Nevertheless, few data are available on gender differences in the response to antiparkinsonian drugs. Safinamide is a multimodal drug with positive effects on motor and non-motor fluctuations that might improve patients' care and quality of life. Objective: To analyze gender differences on clinical effects of safinamide in PD patients treated in real-life conditions during the SYNAPSES trial. Methods: SYNAPSES was a multinational, multicenter, observational study. At baseline, patients with PD diagnosis received safinamide as an add-on to levodopa and were followed up for 12 months, with visits performed every 4 months. A new statistical analysis was performed to describe the efficacy of safinamide in men and women on motor complications, motor symptoms, and adverse events. Results: Six hundred and sixteen (38%) out of 1,610 patients enrolled in the SYNAPSES study were women and 994 (62%) men. Safinamide improved motor symptoms and motor complications (fluctuations and dyskinesia) in both genders, with a good safety profile and without requiring any change in the concomitant dopaminergic therapy. Clinically significant improvements, according to the criteria developed by Shulman et al., were seen in 46% of male and female patients for the UPDRS motor score and 43.5% of men vs. 39.1% of women for the UPDRS total score. Conclusions: Safinamide was effective in improving motor fluctuations and dyskinesia and proved to be safe in both male and female patients with PD. Further prospective studies, specifically addressing potential gender differences in response to PD therapies, are needed to develop tailored management strategies.

Abstract
BACKGROUND AND OBJECTIVES The use of immunoglobulin (IG) solutions as an immunomodulatory therapy in certain neurological conditions has become an established modality and represents a significant proportion of total IG use. The estimation of the evidence-based potential demand designated as the latent therapeutic demand (LTD) for IG in these diseases is required for adequate planning of the plasma supply required to manufacture the product. MATERIALS AND METHODS The diseases studied included chronic inflammatory demyelinating polyneuropathy (CIDP), Guillain-Barré syndrome (GBS) and multifocal motor neuropathy (MMN). The LTD for IG was assessed using a decision analysis model, using Microsoft Excel. The model analysed the epidemiological and clinical factors contributing to IG usage. One-way sensitivity analysis and probabilistic sensitivity analysis derived the LTD in grams per 1000 inhabitants. The key variables included the treatment schedule and the prevalence of the disease. RESULTS The model estimates that an average annual IG demand and standard deviation for CIDP, GBS and MMN in the United States is 83.05 ± 24.5, 6.1 ± 3.2 and 36.1 ± 25.5 g/1000 inhabitants, respectively. CONCLUSION Together with previous work on the LTD for IG in immunodeficiencies, these results indicate that current IG usage reflects the estimated LTD for the main indications for IG in the United States The wide range of LTD found in all these studies emphasizes the need for more precise assessment of the underlying variables, particularly disease prevalence and dosage. Further studies on other indications such as secondary immunodeficiencies will augment these results and will assist in guiding demand planning for IG use and plasma collection in the United States and inform blood policy in other countries.

Abstract
Purpose The purpose of the present study was to evaluate the nailfold capillary morphological features in patients with exfoliative glaucoma (XFG) and compare them with those pertaining to primary open-angle glaucoma (POAG), normal controls and subjects with exfoliation syndrome (XFS). The second purpose was to investigate all parameters related to platelet function on the hemogram, including the platelet count (PLT), the mean platelet volume (MPV), platelet distribution width (PDW), and plateletcrit (PCT) in patients with XFG. These parameters were subsequently compared with those belonging to normal controls, POAG and XFS subjects. Methods This case control study involved 152 consecutive patients that were examined at the Glaucoma Department of Clinic for Eye Diseases, Clinical Centre of Serbia, as the referral center for glaucoma in Serbia, between June 2016 and December 2017. Results Regarding capillaroscopic characteristics, statistically significant difference was found in capillary diameter and tortuosity between the XFG and POAG group (p = 0.050 and p = 0.035) and the XFG and NC group (p = 0.003 and p = 0.044), as well as in the distribution of capillary loops and avascular zones between the XFG and NC group (p = 0.014 and p = 0.004). The subjects with XFG had lower PLT values compared to POAG patients (p = 0.022). Conclusions In conclusion, to the best of our knowledge, this study marks the first attempt to evaluate capillary morphology as well as to investigate all parameters related to platelet function on the hemogram, in patients with newly diagnosed XFG. Our findings revealed nailfold capillary morphological vascular changes in XFG patients. The subjects with XFG had lower PLT values and a higher MPV serum parameter compared to normal controls and patients with POAG. Further research in this field should therefore aim to evaluate the consequences of the aforementioned microvascular abnormalities in patients with XFG.

Abstract
Background Chemotherapy-induced peripheral neurotoxicity (CIPN) is a severe adverse effect in patients receiving antitumor agents, and no effective treatment is available. Although the mechanisms responsible for the development of CIPN are poorly understood, recent findings make neuroinflammation an attractive target to be investigated, particularly when neuropathic pain is a prominent feature such as after bortezomib administration. The aim of our study was to evaluate the effect of intravenous immunoglobulins (IVIg) delivery in chronic CIPN. The related neuro-immune aspects were investigated in a well-characterized rat model of bortezomib-induced peripheral neurotoxicity (BIPN). Methods After determination of a suitable schedule based on a preliminary pharmacokinetic pilot study, female Wistar rats were treated with IVIg 1 g/kg every 2 weeks. IVIg treatment was started at the beginning of bortezomib administration (“preventive” schedule), or once BIPN was already ensued after 4 weeks of treatment (“therapeutic” schedule). Neurophysiological and behavioral studies were performed to assess the extent of painful peripheral neurotoxicity induced by bortezomib, and these functional assessments were completed by pathologic examination of peripheral nerves and intraepidermal nerve fiber quantification (IENF). The role of the innate immune response in BIPN was investigated by immunochemistry characterization of macrophage infiltration in peripheral nerves. Results Both schedules of IVIg administration were able to significantly reduce bortezomib-induced heat and mechanical allodynia. Although these changes were not evidenced at the neurophysiological examination of peripheral nerves, they behavioral effects were paralleled in the animals treated with the preventive schedule by reduced axonopathy in peripheral nerves and significant protection from loss of IENF. Moreover, IVIg administration was very effective in reducing infiltration in peripheral nerves of macrophages with the M1, pro-inflammatory phenotype. Conclusion Our results suggest a prominent role of neuroinflammation in BIPN and that IVIg might be considered as a possible safe and effective therapeutic option preventing M1 macrophage infiltration. However, since neuropathic pain is frequent also in other CIPN types, it also indicates the need for further investigation in other forms of CIPN.

Abstract
Multifocal motor neuropathy (MMN) is a rare, chronic, motor neuropathy that progressively impairs physical functioning and quality of life. Randomised controlled trials have shown that high-dose intravenous immunoglobulin (IVIg) is superior to placebo in improving muscle strength and disability, but many patients require periodic infusions to maintain long-term improvement. This observational, multicentre, retrospective study investigated the efficacy and tolerability of human normal immunoglobulin (Ig VENA) at high intravenous infusion rates in 20 MMN patients (14 male, 6 female). Thirty days after the first infusion, there was an improvement of at least 1 point in two muscles compared to baseline on the Medical Research Council (MRC) scale and of 1 point in the ONLS (Overall Neuropathy Limitation Scale) scale in 15 patients (75%) and 10 patients (50%), respectively; 45% improved on both scales. At 6 months, 100% of 12 patients had improved on the MRC and 79% of 14 patients had improved on the ONLS scale; 83% improved on both scales. All reported adverse drug reactions (ADR) were mild, transient and possibly related to the study drug. Four patients (20%) reported ADRs, three reported headache and one fever. There were no serious or unexpected ADRs. By confirming that high-dose Ig VENA is efficacious and well tolerated, this study adds to the evidence base for IVIg in MMN and potentially increases clinicians' and patients' choice of therapy.

Abstract
During the European Life+ project PhotoPAQ (Demonstration of Photocatalytic remediation Processes on Air Quality), photocatalytic remediation of nitrogen oxides (NOx), ozone (O3), volatile organic compounds (VOCs), and airborne particles on photocatalytic cementitious coating materials was studied in an artificial street canyon setup by comparing with a colocated nonactive reference canyon of the same dimension (5 × 5 × 53 m). Although the photocatalytic material showed reasonably high activity in laboratory studies, no significant reduction of NOx, O3, and VOCs and no impact on particle mass, size distribution, and chemical composition were observed in the field campaign. When comparing nighttime and daytime correlation plots of the two canyons, an average upper limit NOx remediation of ≤2% was derived. This result is consistent only with three recent field studies on photocatalytic NOx remediation in the urban atmosphere, whereas much higher reductions were obtained in most other field investigations. Reasons for the controversial results are discussed, and a more consistent picture of the quantitative remediation is obtained after extrapolation of the results from the various field campaigns to realistic main urban street canyon conditions.

Abstract
The aim of this study was to define features of Guillain-Barré syndrome in a large cohort of patients from three Western Balkans countries. Data from adult Guillain-Barré syndrome (GBS) cases from 2009 to 2013 were retrospectively obtained from all tertiary health care centers. During the 5-year period, 327 new cases of GBS were identified with a male to female ratio of 1.7 : 1. The most common GBS variants were demyelinating (65%) and axonal (12%). At nadir 45% of patients were chair-bound, confined to bed, or required assisted ventilation, while 5% died. The crude incidence of GBS in Serbia and Montenegro was 0.93 per 100,000 population, and age-adjusted incidence according to the world standard population was 0.86 per 100,000. Incidence was particularly high in 50- to 80-year-old men. Statistically significant seasonal variations of GBS were not observed. This study of patients with GBS in the Western Balkans allows us to prepare the health system better and to improve the management of patients. This study also opens opportunities for international collaboration and for taking part in the multinational studies on GBS.

Abstract
OBJECTIVES To analyze frequency and type of personality pattern in patients with myotonic dystrophy type 1 (DM1), to correlate these findings with clinical data, and to assess its possible influence on quality of life (QoL). MATERIALS AND METHODS This cross-sectional study comprised 62 patients with DM1. Following measures were used: Muscular Impairment Rating Scale, Raven's Standard Progressive Matrices (RSPM), Millon Multiaxial Clinical Inventory I (MMCI), SF-36, and Individualized Neuromuscular Quality of Life (INQoL) questionnaires. RESULTS The presence of at least one pathological personality trait with score above 85 on MMCI was found in 47 (75.8%) patients. After clinical interview, 36 (58.1%) subjects had significant personality impairment. The most common personality trait in our cohort of patients was dependent found in 51.6% of patients, followed by paranoid (38.7%). Higher score on dependent personality scale correlated with lower education (rho = -0.251, P = 0.049). Dependent personality scores significantly differed between patients with physical and intellectual work (93.1 ± 8.9 vs 66.9 ± 31.7, P = 0.011). Paranoid score was higher in patients with lower education (rho = -0.293, P = 0.021), lower score on RSPM test (rho = -0.398, P = 0.004) and larger number of CTG repeats (rho = 0.254, P = 0.046). Presence of dependent personality was not in association with QoL scores (P > 0.05). On the other hand, patients with paranoid personality trait had worse QoL than those without it (P < 0.05). CONCLUSION Almost 60% of our patients with DM1 had clinically significant personality impairment, with dependent and paranoid personality patterns being the most common. Paranoid personality may decrease QoL in these patients, which gives us new opportunities for symptomatic therapy in DM1.

Abstract
Background/Aim. Diabetic polyneuropathy is defined as the presence of
clinical or subclinical symptoms and/or signs of peripheral nerve damage in
patients with diabetes mellitus in the absence of the other causes of
peripheral neuropathy. The aim of this study was to assess healthrelated
quality of life (HRQoL) in patients with diabetic polyneuropathy and its
correlation with clinical and neurophysiological findings. Methods. This
study comprised 60 patients with distal, symmetric, sensorimotor diabetic
polyneuropathy and type 2 diabetes mellitus. For evaluation of clinical
findings the following scales were used: Medical Research Council strenth
score (MRC sum score), Inflammatory Neuropathy Cause and Treatment (INCAT)
disability scale (arm disability and leg disability scales), INCAT sensory
sum score, Hamilton depression and anxiety rating scales. Nerve conduction
study (NCS) was performed on the motor part of the median and peroneal
nerves, the sensory part of the median nerve and sural nerve. All the
patients completed the Serbian version of the SF-36 questionnaire as a
measure of HRQoL. Results. Our results showed mild to moderate QoL impairment
in the patients with diabetic polyneuropathy with no difference in physical
and mental composite scores (p > 0.05). The age of the patients, mean MRC sum
score, arm disability scale score, leg disability scale score and mean INCAT
sensory sum score correlated with scores in the SF-36 questionnaire (p <
0.01). The patients with higher scores of anxiety and depression had
significantly worse health perception for all QoL domains, for both composite
scores and for the total SF-36 score (p < 0.01). Both motor and sensory NCS
parameters of the median nerve showed significant correlations with QoL
scores (p < 0.05). Conclusion. Our results showed mild to moderate QoL
impairment in the patients with diabetic polyneuropathy. HRQoL significantly
correlated with the age of the patients, muscle strength, disability, sensory
complaints, depressiveness and anxiety of the patients. Electrophysiological
examination of median nerve significantly correlated with QoL in the patients
with diabetic polyneuropathy.

Abstract
BACKGROUND The aim of this study was to analyze the prevalence and incidence of adult-onset myasthenia gravis (MG) in the Belgrade population from 1979 to 2008. METHODS Data on the number of MG patients and their basic demographic and clinical characteristics were collected from hospital records (1979-1992) and the Belgrade MG Registry (1993-2008). Incidence and prevalence were standardized by the direct method (using the world standard population). A time-trend analysis of MG incidence was performed using a linear regression model. RESULTS During the study period 562 cases (316 women, 246 men) were registered. On December 31st, 2008, the standardized prevalence (according to the world standard population) was 188.3/1,000,000 (women: 237.8/1,000,000; men: 139.4/1,000,000). The average annual standardized incidence rate was 13.3/1,000,000 (women: 14.1/1,000,000; men: 12.2/1,000,000). The incidence rates tended to increase significantly in both sexes during the study period (y = 3.299 + 14.363x, p = 0.002). Age-specific incidence rates for women demonstrated a bimodal pattern, with the first peak in the 20- to 29-year age group and the second one in the ≥70-year group. For both genders, an increase in age-specific incidence rates was registered for all age groups, although this was significant (p = 0.001) only for an MG onset of ≥60 years of age. CONCLUSIONS The study confirms an increase in the incidence of MG in the area of Belgrade during the study period, especially for those with MG onset after 60 years of age.

Abstract
A mycotic aneurysm of the thoracic aorta is a rare diagnosis with high mortality. We present two cases of endovascular reconstruction of mycotic descending thoracic aorta. Specific or nonspecific bacterial or other infectious agent in serial samples of blood, urine, cerebrospinal fluid, and pleural puncture was not detected in the first case, but we found in sputum sample Mycobacterium tuberculosis in the second patient. We empirically began by administering broad-spectrum intravenous antibiotics in the first case, with preoperative antibiotic prophylaxis and antituberculotic drugs therapy in the second case, and continued with the same medication for 4 months after endovascular repair. Control computed tomographic scans 6 months after reconstruction showed no endoleak in both patients. Repair of mycotic descending thoracic aortic aneurysms by endoluminal stent graft is reasonable alternative to open surgical intervention. A broad-spectrum antibiotic therapy has a high significance in the treatment of patients with mycotic aneurysm.

Abstract
Most primary aortoduodenal fistulas occur in the presence of an aortic aneurysm, which can be part of immunoglobulin G4 (IgG4)-related sclerosing disease. We present a case who underwent endovascular grafting of an aortoduodenal fistula associated with a high serum IgG4 level. A 56-year-old male underwent urgent endovascular reconstruction of an aortoduodenal fistula. The patient received antibiotics and other supportive therapy, and the postoperative course was uneventful, however, elevated levels of serum IgG, IgG4 and C-reactive protein were noted, which normalized after the introduction of steroid therapy. Control computed tomography angiography showed no endoleaks. The primary aortoduodenal fistula may have been associated with IgG4-related sclerosing disease as a possible complication of IgG4-related inflammatory aortic aneurysm. Endovascular grafting of a primary aortoduodenal fistula is an effective and minimally invasive alternative to standard surgical repair.

Abstract
OBJECTIVE To assess lipid composition of the intrinsic tongue muscles in patients with myasthenia gravis (MG). METHODS This study included 15 MG patients with antibodies against muscle-specific kinase (MuSK), 15 matched MG patients with antibodies against acetylcholine receptor (AChR) and 15 matched healthy subjects. Middle posterior region of the tongue was analyzed by single voxel point-resolved proton magnetic resonance spectroscopy (MRS) using 1.5T MRI scanner. RESULTS MRS obtained from subject with AChR MG showed a broad resonance arising from methylene groups of lipids (PMN) with no observable shoulder attributed to methyl groups (PML). Full-width at half maximum (FWHM) of PMN+PML peak showed higher value in patients with AChR MG in comparison to healthy subjects and MuSK MG patients (p<0.05). In patients with MuSK MG, the shape and FWHM of PMN+PML peak was similar as in healthy subjects (p>0.05), with tendency toward increased ratio between PMN and resonance from vinyl protons of lipids (PV). In both AChR and MuSK MG, total creatine resonance (creatine+phosphocreatine, CP) was almost absent with significant increase of PMN/CP ratio in comparison to healthy subjects (p<0.05). CONCLUSION MRS is useful in revealing muscle lipid composition in MG. In patients with AChR MG, MRS showed increased lipid content in the tongue muscles due to the lipid migration from intra- to extramyocellular space. Finding in patients with MuSK MG might reflect intramyocellular lipid deposition in the tongue. CP decrease in tongue muscles indicated impairment of oxidative metabolism in both AChR MG and MuSK MG.

Abstract
Introduction. The ultrasound diagnostics of the optic nerve includes the analysis of the optic nerve disc (PNO) and measuring of its retrobulbar diameter. With B-scan, by Schraeder's method, it is possible to measure very precisely the optic nerve, the pial diameter, the normal values for the pial diameter being 2.8-4.1 mm. In glaucoma, the disease that is most frequently associated with higher intraocular pressure, there comes the destruction of nerve fibres, which can be visualized as the excavation of the optic nerve disc. Objective. In this paper, we were interested in finding whether in glaucoma, and in what phase of the disease, the optic nerve starts growing thinner. Aware of many forms of this very complex disease, we were interested in knowing if the visualization of excavation on the optic nerve disc is related to diminishing of the pial diameter of the retrobulbar nerve part. Methods. There were treated the patients who had already had the diagnosis of glaucoma and the visualized excavation of the optic disc of various dimensions. Echographically, there was measured the thickness of the retrobulbar part of the optic nerve and the finding compared in relation to the excavation of the optic disc. Results. In all eyes with glaucoma, a normal size of the retrobulbar part of the optic nerve was measured, ranging from 3.01 to 3.91 mm with the median of 3.36 mm. Also, by testing the correlation between the thickness of the optic nerve and the excavation of the PNO, by Pearson test, we found that there was no correlation between these two parameters (r=0.109; p>0.05). Conclusion. In the patients with glaucoma, the retrobulbar part of the optic nerve is not thinner (it has normal values), even not in the cases with a totally excavated optic disc. There is no connection between the size of the PNO excavation and the thickness of the retrobulbar part of the optic nerve.
