RESUMEN

Purpose: To evaluate the efficacy of laser peripheral iridotomy (LPI) in preventing deterioration in eyes with ocular hypertension (OHT) and concave configuration of the iris. Materials and Methods: This was a retrospective study, which was carried out within a period of 3-5 years. Twenty-four patients with OHT and concave irises were treated with LPI and followed up periodically. IOP, central corneal thickness (CCT), anterior chamber depth (ACD), scleral spur angle (SSA), global neuroretinal rim (NRR) thickness, and global retinal nerve fiber layer (RNFL) were examined before and after LPI. Results: The average age of the 24 patients was 14.21 ± 1.41 (13-17.5) years on admission. The initial IOP of the 48 eyes was 23.21 ± 1.56 mmHg in RE and 22.96 ± 2.1 mmHg in LE before LPI. All 48 eyes had concave irises in both eyes. All eyes treated with LPI have shown iris flattening, which has persisted during follow-up (mean 1.54 ± 0.9 years). At the last follow-up visit, the average IOP was 17.58 ± 2.63 (14-21) mmHg in RE and 17.58 ± 2.86 (14-21) mmHg in LE, which was statistically lower than that of the baseline (p < 0.001). There were significant changes in SSA in both eyes and global RNFL in RE after LPI. Conclusions: In the current study, LPI resulted in an IOP-lowering effect and iris flattening in adolescent eyes with a concave configuration of the peripheral iris.

RESUMEN

PURPOSE: The aim of our study was to determine endothelin-1 (ET-1) concentration in chronic idiopathic uveitis in children and adolescents depending on anatomical location and grade of inflammation. METHODS: The cross-sectional study was conducted among 17 patients with chronic idiopathic uveitis and 22 healthy controls. Concentration of ET-1 in serum was determined using a commercially available ELISA kit. The concentration of C reactive protein (CRP) in serum was determined by immunoturbidimetric method using CRP4 reagent kit (Roche Diagnostics GmbH, Mannheim, Germany). RESULTS: Statistically significant difference between ET-1 concentration in patients with chronic idiopathic uveitis and controls was found 1.33 (1.22; 1.48) vs 1.93 (1.1; 3.11), p = 0.008). No correlations were found between ET-1 concentration and age, either in chronic idiopathic uveitis patients or controls. Nine out of 17 patients presented with anterior uveitis, 5 with posterior and 3 with panuveitis. There were no differences in ET-1 concentration between anterior, posterior and panuveitis (p = 0.634), and in terms of grade of inflammation. CONCLUSION: ET-1 expression is disturbed in pediatric chronic idiopathic uveitis irrespective of the anatomical location and grade of inflammation. Lower expression of ET-1 plays a crucial role in disturbed vascular tone control and can result in permanent visual impairment in chronic non-infectious uveitis.

RESUMEN

PURPOSE: To assess the effect of repeated intravitreal ranibizumab injections (RI) and aflibercept injections (AI) on the corneal endothelium and central corneal thickness (CCT) in patients with age-related macular degeneration (AMD). MATERIALS AND METHODS: In the retrospective study, 110 eyes of 106 patients, aged 52 to 93 years, were analyzed. Fifty eyes were treated only with RI (I group), and 60 eyes were treated only with AI (II group). Every patient received one intravitreal injection of 0.5 mg of ranibizumab once a month or 2 mg of aflibercept for 3 subsequent months. Each patient received only 3 injections during the whole observation period. Corneal analysis was obtained with the specular microscope. Examinations were performed before initial treatment, after each injection, and 6 months after the first injection. Analysis included corneal endothelial cell density (ECD), hexagonal cell percentage (% Hex), coefficient of variation (CoV), and CCT. RESULTS: There was a statistically significant ECD loss, regardless of the type of the anti-VEGF agent. The mean ECD value in the I group was 2397 ± 459 cells/mm2 before RI, 2389 ± 459 cells/mm2 after the first RI, 2386 ± 467 cells/mm2 after the second RI, 2378 ± 475 cells/mm2 after the third RI, and 2357 ± 460 cells/mm2 6 months after the first RI. The mean ECD value in the II group was 2448 ± 493 cells/mm2 before treatment, 2456 ± 498 cells/mm2 after the first AI, 2426 ± 496 cells/mm2 after the second AI, 2402 ± 488 cells/mm2 after the third AI, and 2348 ± 473 cells/mm2 6 months after the first AI. In comparison with the group treated with RI, the group treated with AI presented a greater ECD loss at each measuring point. The percentage of hexagonal cells was decreased in both groups. There was a slight increase in polymegathism in both treated groups. Ranibizumab proved to cause a small increase in CCT, while CCT remained unchanged in the aflibercept group. CONCLUSIONS: Repeated intravitreal injections of 0.5 mg of ranibizumab or 2 mg of aflibercept can influence the morphology of the corneal endothelium but not CCT.

RESUMEN

The aim of this study is to evaluate the levels of enothelin-1 (ET-1) in children and adolescents with high myopia and its association with the axial length of the eye and the presence of myopic retinal degeneration. The cross-sectional study was carried out in 57 patients with high myopia and 29 control subjects. Serum concentrations of ET-1 were measured using enzyme-linked immunosorbent assay (ELISA) kit. A significantly lower concentration of ET-1 in highly myopic patients compared to controls was found (1.47 (0.91; 1.87) vs. 1.94 (1.1; 2.69) pg/mL, p = 0.005). In patients with high myopia, a weak negative correlation between ET-1 concentration and the longest axial length out of the two eyes was found (r = -0.255, p = 0.0558). Further analysis revealed statistically significant differences in ET-1 concentration between patients with the axial length of the eye > 26 and ≤ 26 mm (p < 0.041) and patients with the axial length of the eye > 26 mm and controls (p < 0.001). ET-1 expression is disturbed in highly myopic children and adolescents. Lower ET-1 concentration in patients with the axial length of the eye > 26 mm may co-occur with high myopia and should be considered a risk factor in the pathophysiology of high myopia progression.

RESUMEN

The aim of this work was to determine the concentration of trace elements, zinc, copper, selenium, manganese, and Cu/Zn ratio, in scalp hair samples of children and adolescents with myopia. The study included 92 children (mean age 14.5 ± 2.5 years) with myopia and 43 healthy persons (mean age 11.8 ± 4.7 years). Each patient had a complete eye examination. Trace element concentrations in hair were determined by atomic absorption spectrometry. Cu/Zn ratio was also calculated. The zinc level in the hair of myopic patients was significantly higher (260 µg/g) in comparison to the control group (130 µg/g). There was a significantly lower Cu/Zn ratio in myopic patients (0.045) compared with controls (0.07). An insignificant difference was observed in the hair level of copper, selenium, and manganese between patients and controls. The results show that trace elements may play a significant role in the pathogenesis of myopia. Further studies should pay more attention to determine the effect of trace element on children myopia.

RESUMEN

INTRODUCTION: Citrate is an old metabolite which is best known for the role in the Krebs cycle. Citrate is widely used in many branches of medicine. In ophthalmology citrate is considered as a therapeutic agent and an useful diagnostic tool-biomarker. OBJECTIVES: To summarize the published literature on citrate usage in the leading causes of blindness and highlight the new possibilities for this old metabolite. METHODS: We conducted a systematic search of the scientific literature about citrate usage in ophthalmology up to January 2018. The reference lists of identified articles were searched for providing in-depth information. RESULTS: This systematic review included 30 articles. The role of citrate in the leading causes of blindness is presented. CONCLUSIONS: Citrate might help inhibit cataract progression, in case of questions confirm glaucoma diagnosis or improve cornea repair treatment as adjuvant agent (therapy of ulcerating cornea after alkali injury, crosslinking procedure). However, the knowledge about possible citrate usage in ophthalmology is not widely known. Promoting recent scientific knowledge about citrate usage in ophthalmology may not only benefit of medical improvement but may also limit economic costs caused by leading causes of blindness. Further studies on citrate usage in ophthalmology should continuously be the field of scientific interest.

RESUMEN

OBJECTIVES: The main aim of the present study was to examine a possible role of plasma and urine citrate levels as glaucoma indicators in school-aged children with glaucoma diagnosis. PATIENTS: 34 school-aged children with a glaucoma diagnosis (mean age 15.69±1.86 years) were qualified for the study group and 34 patients with no ophthalmological ailments were qualified for the control group (mean age 16.1±1.98 years). Plasma and urine citrate levels in the study and the control group (Kruskal-Wallis test) were compared. RESULTS: Plasma citrate levels in the study (16.33±4.51 mg/L) and the control group (19.11±3.66 mg/L) were different; the statistical significance (p=0.0036). Plasma citrate concentrations were significantly lower in the study group in comparison with the control group. There were no statistically important differences between the study group (291.12±259.13 mg/24 hours; 275.82±217.57 mg/g) and the control group (434.88±357.66 mg/24 hours; 329.81±383.27 mg/g) including urine citrate level (p=0.052) and urine citrate to creatine ratio (p=0.4667). CONCLUSION: Plasma citrate concentration might be considered as glaucoma biomarker in paediatric population.

RESUMEN

The purpose of the present study was the assessment of the serum concentration of antioxidant microelements-zinc, copper, selenium, manganese, and Cu/Zn ratio in children and adolescents with myopia. Eighty-three children were examined (mean age 14.36 ± 2.49 years) with myopia. The control group was 38 persons (mean age 12.89 ± 3.84 years). Each patient had complete eye examination. The serum concentration of zinc, copper, manganese, and selenium was determined by atomic absorption spectrometry. Cu/Zn ratio, which is the indicator of the oxidative stress, was also calculated. The average serum concentration of zinc in myopic patients was significantly lower (0.865 ± 0.221 mg L-1) in comparison to the control group (1.054 ± 0.174 mg L-1). There was significantly higher Cu/Zn ratio in myopic patients (1.196 ± 0.452) in comparison to that in the control group (0.992 ± 0.203). The average serum concentration of selenium in the study group was significantly lower (40.23 ± 12.07 µg L-1) compared with that in the control group (46.00 ± 12.25 µg L-1). There were no essential differences between serum concentration of copper and manganese in the study group and the control group. Low serum concentration of zinc and selenium in myopic children may imply an association between insufficiency of these antioxidant microelements and the development of the myopia and could be the indication for zinc and selenium supplementation in the prevention of myopia. Significantly, higher Cu/Zn ratio in the study group can suggest the relationship between myopia and oxidative stress.

RESUMEN

BACKGROUND: A significant increase in myopia among children and teenagers can be observed all over the world. Yet at the same time, there is still an insignificant number of studies concerning this health problem. The aim of this study was to assess the level of trait anxiety among myopic group of teenagers in comparison to teenagers with emmetropia, and to confirm whether the level of trait anxiety relates to age and gender. METHODS: Two hundred thirty-nine students aged 13-17 years were included in the study. The study group comprised 114 persons with myopia (81 girls and 33 boys), while the control group comprised 125 persons without refractive error (79 girls and 46 boys). Volunteers completed a set of questionnaires including: personal data, State-Trait Anxiety Inventory for Children (STAIC) (13-14 year-olds), or State-Trait Anxiety Inventory (STAI) (15-17 year-olds). The trait anxiety subscales were thus analyzed. RESULTS: Among younger adolescents (13-14 years of age) with myopia there was a significantly higher incidence of pathological intensification of anxiety as a constant trait. After taking into account the distribution of gender, there was a higher level of trait anxiety in the group of boys with myopia than in the control group aged 13-17 years and 13-14 years. There was also a higher level of trait anxiety detected in males than in females. CONCLUSIONS: Myopia may affect the level of trait anxiety among 13-14-year-olds. In both age groups of girls, a higher percentage of patients with high level of anxiety was discovered (≥7 sten), as compared to their peers without vision defects. Our results can contribute to a more accurate analysis of young teenagers' psychological problems, especially among boys diagnosed with myopia.

RESUMEN

PURPOSE: The authors examined macular function in preterm-born children, using multifocal ERG (mfERG). Possible alterations in P1 amplitudes, P1 amplitudes density and P1 implicit time between school-age children with history of prematurity and their peers were researched. The correlations between parameters of mfERG responses and birth weight, gestational age, macular volume and central macular thickness were verified. METHODS: A group of 18 preterm-born school-age children were analyzed (mean age 10.18 ± 1.21 years). The study group was compared to the group of 15 peers born appropriate for gestational age (mean age 10.8 ± 1.52 years). The mfERG was evaluated in all children. RESULTS: There were statistically significant differences for P1 amplitudes from ring 1 (p = 0.0001) and P1 amplitudes density from ring 1 (p = 0.0001). Calculating the correlation coefficients, we receive significant results for P1 amplitudes from ring 1 versus gestational age (r = 0.54; p = 0.026), birth weight (r = 0.54; p = 0.026) and central macular thickness (r = -0.62; p = 0.008), and for P1 amplitudes density from ring 1 versus central macular thickness (r = -0.51; p = 0.034). CONCLUSIONS: The study suggests that P1 amplitudes and P1 amplitudes density vary in preterm-born children in comparison with their peers born appropriate for gestational age, which might suggest discreet macular dysfunction. The correlation between low birth weight, early gestational age, central macular thickness and mFERG components from ring 1 might evidence that decreased bipolar cells density caused by premature birth is the result of altered development of central retina reflecting in structural anomalies of the fovea.

RESUMEN

Objective: To determine possible alterations of P100 and P1 amplitudes and latencies in school-aged children with a history of a central nervous system tumour. Material and methods: The pattern visual evoked potential and flash visual evoked potential testing was performed in 42 school- -aged children: 15 patients with a history of the central nervous system tumour (mean age of 13.44 ± 2.41 years and 13.75 ± 2.29 years, respectively) and 27 healthy subjects as a control group (mean age 11.84 ± 1.44 years, and 14.78 ± 4.26 years, respectively). Results: P100 amplitudes of pattern visual evoked potentials were statistically decreased in the study group as compared to the control group. The only statistically signifcant difference between the study group and the controls was latencies recorded from O1 in 15-minute stimuli. P2 amplitudes of flash visual evoked potentials were decreased and latencies were increased in the study group, however, the differences were not statistically significant. Conclusions: Visual evoked potential alterations can be a sign of functional disturbances of the visual system in patients with any central nervous system tumour. Therefore, a diagnostic process of a central nervous system tumour should include a thorough ocular exam, even in patients with normal visual acuity.

RESUMEN

Purpose: Retrospective analysis of patients with traumatic hyphema, including type of injury, treatment and visual outcome. Material and methods: We analysed a cohort of patients after blunt trauma, who were examined and treated between 2011­ ­2015. In each case, the baseline and ultimate visual acuity was determined, followed by slit lamp examination, intraocular pressure measurement, indirect binocular ophthalmoscopy of the fundus, ultrasound scan and OCT Visante. The type of treatment as well as duration of inpatient treatment and late complications were assessed for each case. Results: 45 patients (45 eyes) with traumatic hyphema due to blunt ocular trauma were enrolled. 42 of them were boys (93.3%), and 3 were girls (6.7%). The age range was 2.5­17.5 years (mean age of 11.92 ± 3.75 years). Upon admission, 10 (22.2%) children had full visual acuity (1.0). The most common injuries concomitant with hyphema included iridodialysis, corneal oedema, mydriasis and corneal erosion. Secondary hemorrhage occurred three days following injury in only one (2.2%) patient. The mean duration of inpatient admission was 4.3 days (ranged from 2 to 8 days). At the last follow-up visit, 36 (80%) patients had a full visual acuity of 1.0. Conclusions: Visual outcomes improve with earlier treatment commencement. Conservative management was sufficient to resolve traumatic hyphema in reported cases

RESUMEN

PURPOSE: The objective of our study was to examine a possible influence of gestational age, birth weight, and Apgar score on amplitudes and latencies of P100 wave in preterm born school-age children. MATERIALS AND METHODS: We examined the following group of school-age children: 28 with history of prematurity (mean age 10.56 ± 1.66 years) and 25 born at term (mean age 11.2 ± 1.94 years). The monocular PVEP was performed in all children. RESULTS: The P100 wave amplitudes and latencies significantly differ between preterm born school-age children and those born at term. There was an essential positive linear correlation of the P100 wave amplitudes with birth weight, gestational age, and Apgar score. There were the negative linear correlations of P100 latencies in 15-minute stimulation from O1 and Oz electrode with Apgar score and O1 and O2 electrode with gestational age. CONCLUSIONS: PVEP responses vary in preterm born children in comparison to term. Low birth weight, early gestational age, and poor baseline output seem to be the predicting factors for the developmental rate of a brain function in children with history of prematurity. Further investigations are necessary to determine perinatal factors that can affect the modified visual system function in preterm born children.

RESUMEN

Purpose. To evaluate the endothelial cell density (ECD) and central corneal thickness (CCT) in adolescents with juvenile open-angle glaucoma (JOAG) and ocular hypertension (OH) and to investigate the influence of topical antiglaucoma medications on ECD and CCT in adolescents with JOAG. Methods. ECD and CCT were investigated in 66 eyes of 33 adolescents with JOAG. Depending on the topical treatment the eyes were classified into 4 groups: (1) topical carbonic anhydrase inhibitor, (2) prostaglandin analogs, (3) beta-blocker, and (4) CAI-beta-blocker combination. ECD and CCT were also checked in 24 adolescents with OH and in control group (33 persons). Results. ECD was significantly lower in eyes with JOAG (2639.5 cells/mm(2)) compared with ECD in eyes with OH (2924.5 cells/mm(2)) and in control group (2955.5 cells/mm(2)). CCT was 0.554 mm in eyes with JOAG, 0.55 mm in eyes with OH, and 0.544 mm in control group. ECD in patients with JOAG was 2730 cells/mm(2) (1 group), 2773.5 cells/mm(2) (2 group), 2539.5 cells/mm(2) (3 group), and 2551 cells/mm(2) (4 group). CCT was 0.556 mm in 1 group, 0.558 mm in 2 group, 0.532 mm in 3 group, and 0.544 mm in 4 group. Conclusions. Our findings indicate that JOAG and OH did not affect CCT, but JOAG has influence on ECD in adolescents. There were no significant differences between ECD and CCT of eyes treated with different kinds of antiglaucoma medications.

RESUMEN

IRU is the most common form of immune reconstitution inflammatory syndrome in HIV-infected patients with cytomegalovirus retinitis who are receiving highly active antiretroviral therapy (HAART). Among patients with CMV in the HAART era, immune recovery may be associated with a greater number of inflammatory complications, including macular edema and epiretinal membrane formation. Given the range of ocular manifestations of HIV, routine ocular examinations and screening for visual loss are recommended in patients with CD4 counts <50 cells/µL. With the increasing longevity of these patients due to the use of HAART, treatment of IRU may become an issue in the future. The aim of this paper is to review the current literature concerning immune recovery uveitis. The definition, epidemiology, pathophysiology, clinical findings, complications, diagnosis, and treatment are presented.

RESUMEN

The diagnosis and treatment of diabetic retinopathy (DR) in young adults have significantly improved in recent years. Research methods have widened significantly, for example, by introducing spectral optical tomography of the eye. Invasive diagnostics, for example, fluorescein angiography, are done less frequently. The early introduction of an insulin pump to improve the administration of insulin is likely to delay the development of diabetic retinopathy, which is particularly important for young patients with type 1 diabetes mellitus (T1DM). The first years of diabetes occurring during childhood and youth are the most appropriate to introduce proper therapeutic intervention before any irreversible changes in the eyes appear. The treatment of DR includes increased metabolic control, laserotherapy, pharmacological treatment (antiangiogenic and anti-inflammatory treatment, enzymatic vitreolysis, and intravitreal injections), and surgery. This paper summarizes the up-to-date developments in the diagnostics and treatment of DR. In the literature search, authors used online databases, PubMed, and clinitrials.gov and browsed through individual ophthalmology journals, books, and leading pharmaceutical company websites.

RESUMEN

PURPOSE: To evaluate the systemic and local factors that contribute to the damage of endothelial cells in diabetic patients and to compare the endothelial structure of the cornea in diabetic and nondiabetic patients. MATERIALS AND METHODS: The endothelial cell density (ECD) and central corneal thickness (CCT) were investigated in 123 eyes of type 1 diabetic patients and in 124 eyes of nondiabetic patients. The mean diabetic patients age was 15.34 ± 3.06 years versus 14.58 ± 2.01 years in the control group. The mean duration of diabetes was 8.02 ± 3.9 years. The corneal endothelium was imaged by the Topcon SP-2000P. RESULTS: The mean ECD in diabetic eyes was 2435.55 ± 443.43 cells/mm(2) and was significantly lower than in control group (2970.75 ± 270.1 cells/mm(2)). The mean CCT was 0.55 ± 0.03 mm in diabetic group versus 0.53 ± 0.033 mm in control group. ECD and CCT significantly correlated only with duration of diabetes. There was no correlation between ECD and CCT and patient age, sex, HbA1C level, and plasma creatinine level. CONCLUSIONS: ECD is decreased and CCT is increased in children and adolescents with diabetes mellitus. Duration of diabetes is the factor that affects ECD and CCT.

RESUMEN

AIM: To evaluate the anterior eye segment in children and adolescents after unilateral ocular trauma, using optical coherence tomography Visante OCT. MATERIAL AND METHODS: 19 patients (17 boys and 2 girls), hospitalized in Department of Pediatric Ophthalmology due to ocular trauma, were examined. Mean age was 12.6 years (6-17 years). 12 patients had blunt ocular trauma, and 7 patients had a penetrating injury. RESULTS: Hyphaema impeded the view in 5 eyes, so Visante OCT was helpful for the right treatment. The anterior chamber shallowing was diagnosed in 9 cases, and anterior chamber deepening in 5 cases. Lens pathology (subluxation, cataract) was recognized in 4 patients. OCT was useful in diagnosis of corneal wound (1 case) and in foreign body removal (1 case). CONCLUSIONS: Visante OCT provides easy visualization and high-resolution documentation. Its ability to image the anterior segment structures despite corneal opacification seems particularly important. This technique can be very useful in children and adolescents with ocular trauma.

RESUMEN

PURPOSE: To evaluate the anterior chamber depth (ACD) measurements in emmetropic, hypermetropic and myopic eyes in children and adolescents using optical coherence tomography (OCT). MATERIAL AND METHODS: 86 patients at the age from 4 to 17 years were examined. 27 patients with mean age 14.0 +/- 2.94 years had myopia with spherical equivalent refraction (RE) from -0.50 to - 19.50 D (mean RE = -8.63 +/- 3.89 D). 29 patients with mean age 8.7 +/- 1.95 years had hypermetropia with RE from +0.50 to +9.00 D (mean RE = +4.49 +/- 2.11 D). 30 patients control group) with mean age 9.8 +/- 1.03 years had emmetropia. The anterior chamber depth was measured by OCT Visante. In myopic eyes measurements of axial length were obtained using ultrasound A scan. RESULTS: 172 eyes (86 subjects) were evaluated. The mean ACD measurement was 3.18 +/- 0.31 mm in myopic eyes, 2.73 +/- 0.2 mm in hypermetropic eyes, and 2.92 +/- 0.11 mm in emmetropic eyes. There were significant differences in ACD between these three groups of eyes (p<0.01). ACD was correlated with spherical equivalent refraction (Spearman correlation, r = -0.688, p<0.001), and axial length (r = 0.388, p = 0.003) in myopic eyes. There were no statistically significant differences in ACD between 30 eyes of 15 patients with anisometropia >3.00 D. CONCLUSIONS: There were significant differences in ACD between emmetropic, hypermetropic and myopic eyes in children and adolescents. ACD was associated with refractive error and axial length in the eyes with myopia. Further observations are necessary on larger number of patients.
