Introduction: Toxoplasmosis is a universally distributed disease caused by toxoplasma gondii. Objective: To describe the epidemiological and clinical characteristics of patients with ocular toxoplasmosis who were treated at the Santiago de Cuba Opthalmological Center Juan Bruno Zayas Alonso. Methods: An observational, cross-sectional study was conducted. The study population consisted of 29 patients of both sexes diagnosed with ocular toxoplasmosis, who were treated at the Santiago de Cuba Opthalmological Center, between December 2020 and December 2022. Variables such as age, sex, sanitary and hygienic conditions of the house, area of residence, affected eye, visual impairment, topography, presentation of the lesion and complications were analyzed. Results: The majority of the population was men (5.2 %) aged 34-49 (44.4 %). According to conditions of the houses, 48 % were regular and 70 % lived in rural areas. The visual impairment was severe (55.5 %) with location in zone I (81.5 %). Recurrent lesions (55.6 %) and one eye affected (92.6 %) predominated. Among the complications, secondary glaucoma (22.2 %). Conclusions: Ocular toxoplasmosis is the most common cause of posterior uveitis. The presence of domestic animals and inappropriate eating habits were identified as key risk factors in this study. [ABSTRACT FROM AUTHOR]

Antiangiogenic drugs are widely used in ophthalmology. They act by inhibiting the vascular endothelial growth factor, reducing the formation of neovessels and their use can cause side effects, such as increased intraocular pressure (IOP), which can lead to the development of glaucoma and irreversible loss of vision. This ocular hypertension can be temporary or require intervention, such as medication or surgery. The aim of this study is to determine whether intravitreal injection of antiangiogenics causes an increase in IOP. A literature search was carried out in the PubMed, Google Scholar and Science Direct databases. After applying the criteria, 9 relevant articles were selected for the literature review. The increase in IOP after anti-VEGF injections is associated with risk factors such as frequency and total number of injections, pre-existing glaucoma and type of retinal disease treated. Although there is variability between studies, it is suggested that repeated injections can destabilize ocular pressure, especially in phakic patients. In addition, the need for monitoring among patients at higher risk was highlighted. Such injections are safe, but increased intraocular pressure has been observed in patients. It is therefore essential to monitor IOP, as this increase can lead to serious complications such as glaucomatous optic neuropathy and irreversible loss of vision. [ABSTRACT FROM AUTHOR]

Introduction: IgG4-associated ocular inflammatory pseudotumor is a rare, non-neoplastic inflammatory process with an incidence of 0.28-1.08 per 100,000 people. The diagnosis of this pathology is one of exclusion, having to meet histopathological criteria, enlargement of a specific organ, and serious concentrations of IgG4. Treatment aims to avoid secondary complications. Clinical case: A 54-year-old woman with no previous reported pathologies, reports that for the past 6 months she has itching at the level of the eyeball and the left eyelid, suddenly and without apparent cause, in addition to decreased visual acuity and retro-ocular pain; this is why she asked for the evaluation. The physical examination revealed normal eye movements, left proptosis, pain on palpation, subconjunctival hyperemia, corneal opacity, absence of red reflex, and the left eye being more resistant to pressure in relation to the contralateral eye. The cranio-thoraco-abdominal tomography reported images at the left ocular level that were suggestive of choroidal melanoma without findings of metastatic activity. Enucleation of the left eye was performed. The specimen was sent to pathology which reported diffuse lymphoplasmacytic infiltrate positive for IgG4. Conclusion: Ocular IgG4 disease is a very rare pathology with non-specific symptoms and complex diagnosis. However, a quick and correct approach is essential to avoid complications.

Introduction: Mucormycosis is a very aggressive infection generated by aerobic fungi that can involve the upper airway and spread to adjacent structures. Objective: To analyze the association between death and ocular exenteration in patients with rhino-orbito-cerebral mucormycosis. Method: The clinical aspects and outcome of patients with rhino-orbito-cerebral mucormycosis were analyzed. Descriptive statistics were used, Chi square was used for association, odd ratio was used for risk, considering a value of p≤0.05 as significant. Results: Of 45, 11 did not meet the inclusion criteria, no associations were found between sex, diabetes with other comorbidities, MROC stages and death, COVID-19 infection, or glycated hemoglobin (HbA1c). However, bone lysis on tomography (p=0.001), type of surgical procedure (p=0.002), and ocular exenteration (p=0.001) were significantly associated with death. Differences were found between C-reactive protein (CRP) levels (p=0.035), erythrocyte sedimentation rate (ESR) (p=0.056), and absolute neutrophil count (p=0.000) with death. Discussion: The decision to undergo ocular exenteration is a complex aspect in patients with MROC. There are authors who point out that the psychological impact is significant in a substantial proportion of patients. Conclusions: The only characteristics associated with death in patients with MROC in the study were the presence of bone lysis on the tomography and ocular exenteration. [ABSTRACT FROM AUTHOR]

Most of the assessment instruments summarize a series of parameters that quantify behavior based on the sense of vision, but do not include physiological measures. The main objective of this research was to record the eye movements of participants by means of an eye tracking device (ET), during the performance of Perception of Differences Test (PDT; CARAS in Spanish) in order to delimit magnitudes such as time or processing speed per item. 44 university students belonging to the Universidad Nacional del Sur in Argentina were evaluated individually, through incidental sampling. A comparative analysis was carried out between the performance in the first 3 minutes and the end of the test, as well as an evaluation of the items grouped by blocks. The results found with the first analysis support the hypothesis that the subjects who need more information to solve the test perform more fixations instead of making longer fixations, and this strategy remains constant throughout the entire task. The second analysis showed an increase in the mean values of resolution times for each item as the resolution of the test progresses, which combined with an increase in the dispersion towards higher values of this characteristic may be an indication of attention fatigue. These findings show that the use of ET in the application of the test provides complementary information that could enhance its evaluation capabilities. [ABSTRACT FROM AUTHOR]

The article "CONCORDANCE BETWEEN RECTAL TEMPERATURE AND OCULAR THERMOGRAPHY IN GUINEA PIGS (Cavia porcellus) ANESTHETIZED WITH ISOFLURANE" published in the journal "Ciencia Veterinaria" addresses the importance of measuring body temperature in guinea pigs during anesthetic procedures. Infrared thermography was used to compare rectal and ocular temperature in guinea pigs anesthetized with isoflurane. The results showed a moderate bias between both measurements, suggesting that thermography may not be clinically acceptable for monitoring body temperature in anesthetized guinea pigs.

Introduction: eye diseases are risk factors that cause accidents in older adults. Objective: to determine the behavior of ocular diseases of the anterior segment and adnexa in the elderly. Methods: an observational, descriptive cross-sectional study was carried out in the Clinic of the Villa Clara Ophthalmology Center from July to December 2022. The universe consisted of 426 patients and the sample was 123. The variables investigated were: age, sex, skin color, history of systemic diseases, history of ocular diseases, ocular symptoms, diseases of the anterior segment and adnexa, municipality of origin and indicated treatment; Absolute and relative percentage frequencies were used. Results: the age of 70 to 79 years (47.2%), the female sex (61.8%) and the white race (52.8%) predominated. High blood pressure (37.4%) and age-related macular degeneration (27.6%) were evident. Decreased visual acuity occurred in 69.1% and cataract was the predominant disease (43.9%). The Municipality of Santa Clara contributed 83 patients. 67.5% received surgical treatment. Conclusions: the elderly are vulnerable to suffering from diseases of the anterior segment and adnexes and there is a predominance of women, ages between 70 and 79 years and a history of high blood pressure and age-related macular degeneration. Cataract is the most common disease, which is why the largest number of patients received surgical treatment. The Municipality of Santa Clara is the one with the greatest origin.

Introduction: Blindness constitutes a health problem worldwide; its main cause is glaucoma. The patient with this clinical entity has a 3 times higher risk of presenting serious bilateral visual disability. Objective: To describe some epidemiologic and clinical aspects of patients with primary closed-angle glaucoma. Method: A descriptive, cross-sectional and prospective study was carried out with 20 people over 40 years with primary closed-angle glaucoma who went to the emergency room of Dr. Juan Bruno Zayas Alfonso Teaching General Hospital in Santiago de Cuba, from September, 2020 to the same period in 2022. Results: In the series there was a prevalence of the 60-69 age group (45.0 %) and females (75 %). Half of the patients (50.0 %) presented visual acuteness in the range lower than 0.1 and papillary excavation higher than 0.7. Conclusions: Primary closed-angle glaucoma is still a health problem; its serious consequences, like the abrupt decrease of vision that can cause irreversible damage to the optic nerve due to the severe ocular hypertension, impose a true challenge for the ophthalmologist in his daily work. The opportune and appropriate treatment of these patients will avoid the deterioration of visual function. [ABSTRACT FROM AUTHOR]

Introduction: This study explores gender differences in the visual processing of images and their relationship with brand love among Generation Z on social media. Methodology: A mixed-method approach combining eye-tracking and surveys was employed. Results: Complex backgrounds divert attention from the product, whereas abstract backgrounds focus the gaze on the product. The presence of human figures, particularly celebrities, reduces attention on the products. Brand elements and identifiers are often overlooked in favor of contextual details. The relationship between visual fixation variables and brand love varies significantly between men and women, although a homogenization of genders is observed in certain variables. Additionally, a higher number of fixations and more dynamic visual exploration are positively correlated with brand love, while longer fixation duration is negatively associated. Discussion: The findings suggest that while gender differences in visual processing persist, these are evolving toward a convergence in cognitive strategies between men and women in Generation Z. Furthermore, the study emphasizes the importance of active visual dynamism in fostering an emotional connection with brands, with nuanced considerations about the effectiveness of prolonged attention. Conclusion: The findings highlight the need to adapt marketing strategies for Generation Z, taking into account the new dynamics of visual processing and their impact on emotional connection with brands.

Introduction: Glaucoma is one of the nosologic entities with more prevalence and constitutes one of the main causes of blindness in the developed world. The intraocular pressure is the only risk factor that can be controlled and is associated with the presence and progression of the disease. Objective: To describe the evolution of patients operated by means of trabeculectomy technique. Methods: An observational descriptive, longitudinal and prospective study of 128 patients with simple chronic glaucoma operated by means of trabeculectomy technique was carried out in the Ophthalmology Center of Santiago de Cuba, from January, 2017 to June, 2019. For this purpose, the following variables were analyzed: age, sex, skin color, preoperative and postoperative visual acuteness, intraocular pressure before and after the operation, as well as postoperative complications. Results: There was a prevalence of male sex (69.5%), 60-69 age group (44.5%) and black skin color (53.1%). Hypertension was the most frequent associated disease and the ocular hypertension was the fundamental risk factor; meanwhile, the main postoperative complication was the hyphema. Conclusions: With trabeculectomy was possible to control ocular tension in most of the patients and the complications that were presented in some of them did not interfere in their clinical course. This technique made it possible to reduce the irreversible damage caused by ocular hypertension of the optic nerve and, consequently, to prevent blindness. [ABSTRACT FROM AUTHOR]

Advances in neuro-technology provide new insights into how individual students learn in educational contexts. However, applying it poses challenges for teachers in natural settings. This paper presents an example of the use and applicability of eye-tracking technology in Higher Education. We worked with a sample of 20 students from three universities (Burgos and Valladolid in Spain and Miño in Portugal). The objectives were: (1) to determine whether there were significant differences in indicators of cognitive effort (FC, FD, SC, PD, VC) found with eye-tracking technology between students with and without prior knowledge; (2) to determine whether there were clusters of learning behavior patterns among students; and (3) to analyze differences in the visualization of behavior patterns. A quasi-experimental design without a control group and a descriptive design were used. The results indicated significant differences in learning outcomes between students with and without prior knowledge. In addition, two clusters were found in indicators of cognitive effort. Finally, a comparative analysis of learning behavior patterns between students in cluster 1 vs. cluster 2 was performed. Eye-tracking technology makes it possible to record large data about the learning process. However, using it in natural educational settings currently requires teachers to have technological and data mining skills. [ABSTRACT FROM AUTHOR]

This article presents the methodological process of creation in the development of the V.S.C.O (Ocular Control Video Synthesizer) software, which is the result of the research-creation project of the same name that gathers evaluation results of its prototype through user-centered design (UCD) tools. The user-software interface is also part of the conceptualization of an artwork that operates in the context of digital art and computational art. The descriptive methodology and mixed approach will allow, through the collection of user data, to delve into the public/player experience that integrates a typology of play in the field of creation and entertainment, thus demonstrating in a perceptual evaluation of the digital artwork how it promotes states of mental relaxation in the audience. The connection between sound and visuals in the V.S.C.O computational system is also appreciated, aligning with the aesthetic and technical purposes of Visual Music, an aesthetic that dates back to the early 20th century and aimed to create a temporal architecture realized in the synesthetic fusion of colors, shapes, and movements. It is expected that the visual and auditory dynamics of the V.S.C.O, through its interaction capabilities with the audience in space, will construct its own temporal architecture, linking it with the technical and poetic aspects of Visual Music.

Introduction and Objective: The aim of our study was to demonstrate the clinical diffe)rences between idiopathic benign paroxysmal positional vertigo (BPPV) and BPPV secondary to acute peripheral vestibular syndrome (APVS). Method: Retrospective case-control study. Data collection was obtained from medical records at our hospital. Demographic and clinical data of patients diagnosed with idiopathic BPPV and BPPV secondary to APVS were collected for analysis. Additionally, in the case group, a correlation was performed between peripheral vestibular deficit, measured through the video head impulse test (vHIT), and the number of maneuvers and time until resolution of BPPV. Results: Seventy-two patients were included, with 64% being women. The control group included 50 patients with idiopathic BPPV and 22 with BPPV secondary to APVS in the case group. In secondary BPPV, the posterior semicircular canal was affected in 100% of cases (OR: 1.2; 95% CI [1.088 - 1.436]). Both groups showed a vertigo resolution rate of 90% and 89%, respectively. The secondary BPPV group had a 4-fold higher recurrence risk (OR: 4.18; 95% CI [1.410 - 12.406]); they required more maneuvers (3.32 ± 2.2 vs. 1.7 ± 1.3, p = 0.004) and more time (61.9 days ± 73.1 vs. 12.9 days ± 9.6, p = 0.007) for BPPV resolution. Significant correlations were found between the difference in mean gain of the vestibulo-ocular reflex (VOR) and the number of maneuvers (r = 0.462, p = 0.030) and the time until resolution (r = 0.577, p = 0.008). Discussion: Clinical differences exist between idiopathic BPPV and BPPV secondary to APVS, primarily in terms of the affected semicircular canal, a higher number of maneuvers, and a longer time in days until BPPV resolution. Furthermore, it was determined that a greater vestibular deficit in a patient with secondary BPPV to APVS requires a higher number of maneuvers and an extended time until BPPV resolution. Conclusions: BPPV secondary to APVS presents a higher risk of recurrence, requires a greater number of maneuvers, and takes longer to resolve compared to idiopathic BPPV. [ABSTRACT FROM AUTHOR]

Diabetic retinopathy (RD) is a complication caused by diabetes. This can cause blindness, becoming a worldwide threat due to the affectation of people at an early age and linked to the labor field. The role of medicine in the diagnosis of this disease is associated to the analysis of pathologies (micro aneurysms, hemorrhages and exudates) presented in fundus images. This task is tedious, time-consuming for medical personnel and it makes delays in diagnosis because of the high demand of RD patients. From the engineering of CAD system designs (Computer-Aided Design) an automated method is proposed for the identification of reference characteristics such as the optical disc, the fovea and the blood vessels. This article presents a methodology for the detection and segmentation of the optical disc and blood vessels. first, a preprocessing stage based on the algorithms of contrast-adaptive histogram equalization (CLAHE) and dynamic diffuse histogram equalization that preserve brightness (BPDFHE) is proposed aiming of improving the fundus image and highlighting the blood vessels for later removal. Next, it is proposed the methodology of segmentation of blood vessels through neural networks that a posteriori, it is going to contribute information for the correct segmentation of the optical disc, which is located through iterative opening and closing morphological operations, demonstrating that it is invariability against pathological lesions of the exudates that coincide in color information with the ocular structure of interest. Once the optic disc is located, the blood vessels inside are removed by inpainting algorithm (Functional Mumford-Shah), which replaces the presence of the blood vessels with statistical information of color discrimination of the optical disc. Finally, the Graph Cut algorithm is implemented for the segmentation of the optical disc. [ABSTRACT FROM AUTHOR]

The Sars-Cov-2 virus, the etiological agent of Covid-19, causes systemic and ocular manifestations in humans. Due to the global repercussion that the pandemic has had, the multisystemic damage it causes and the presence of ocular manifestations, which could be the presentation of the disease, it is decided to carry out the present work to offer a theoretical reference about the ocular manifestations of Covid-19 and some therapeutic guidelines to consider. A bibliographic search was carried out in the Pubmed, Infomed, SciELO and academic Google databases, of articles in Spanish and English, which included new information related to the disease and its impact on eye health. Inflammatory and infectious processes of the visual apparatus, such as conjunctivitis and uveitis, are found with remarkable frequency. In the recovery stage, ocular findings associated with systemic immunosuppression, vasculitic and thromboembolic processes are presented. The indicated therapy does not usually differ from the conventional ones. First-line doctors play an essential role in the timely diagnosis of cases, since ocular manifestations can be the first sign of systemic disease. [ABSTRACT FROM AUTHOR]

Introduction: The ocular neoplasm can affect the eye, annexes and orbit. The effective treatment depends on an early, presumptive and accurate diagnosis. Objective: To characterize patients with eye cancer according to variables of interest. Method: An observational, descriptive and retrospective study of 58 patients with eye malignancy confirmed by means of biopsy was carried out. They were assisted in the Ocular Plastic Surgery Service of the Ophthalmologic Center at Dr. Juan Bruno Zayas Alfonso Teaching General Hospital in Santiago de Cuba, from October, 2015 to the same period in 2020. The mean was used for the quantitative variables. Results: In the series the mean age was of 62.49 years; there was a prevalence of the male sex (51.7 %) and the mixed race color of the skin (53.4 %). The most frequent localization of the tumoral lesions in the annexes was in the lids (53.4 %) and the conjunctive (41.4 %). The predominant histologic types were palpebral basal cell carcinoma (44.8 %) and squamous cell carcinoma of the conjunctive (41.4 %). The estadification of the tumor was established: T1 en 47 patients, T2 and T3 in 4, as well as T4 in 3. Conclusions: The control of the eye cancer is very important, because it allows to trace strategies for the early diagnosis and the appropriate treatment of patients. [ABSTRACT FROM AUTHOR]

The objective of this study was to determine ocular manifestations of toxocariasis in schoolchildren. A study was conducted in two schools in the Anzoátegui state in Venezuela in 2019. The ELISA test was used to determine IgG antibodies against Toxocara spp. The families completed a questionnaire, and the children were clinically evaluated by pediatricians and ophthalmologists. 118 children participated, 18.6% presented anti-Toxocara spp. The clinical manifestations with a statistically significant association were allergic reactions, epiphora, and decreased visual acuity. The ophthalmological evaluation found keratitis, uveitis, iritis, retinal granuloma, endophthalmitis, amaurosis, leukocoria, retinal detachment and endotropia. The findings show a high frequency of eye disease in children with toxocariasis from a state of Venezuela. [ABSTRACT FROM AUTHOR]

Objective: Analyze the results of a new professional service specialized in visual health (PSSVH) for the detection of ocular health problems (OHP) in polymedicated patients and to identify possible factors associated with the appearance and control of these OHP. Methods: Observational and descriptive study. Location: Community pharmacy in Murcia, Spain. Participants: 92 patients suffering at least from a diagnosed or suspected OHP and who used =4 chronic medications were included. Main measurements: Patients were given a protocolised visual health examination (PVHE). The dependent variables were the types of OHP detected in the PVHE and the independent variables were adherence to and knowledge of chronic ophthalmic treatment among others. Results: The total number of OHP was 303 (3.3 OHP/patient), of which 64% were not controlled (OHPNC) and 32.3% were not known to the patient. Most of OHP detected were associated with refraction. 57,1% of the patients undergoing treatment with antiglaucomatous drugs and 100% of those treated for dry eye indicated non-adherence to treatment; 78.6% and 71.4% respectively had no knowledge of this medication. The bivariate analysis showed that age, educational level and profession of the patients are related to the number of OHPNC. Conclusions: The PSSVH allows a large number of OHPNC in polymedicated patients. Main interventions should be aimed at improving adherence to and knowledge of ophthalmic medication, referrals to specialists and advice on ophthalmic correction. [ABSTRACT FROM AUTHOR]

In this paper a 5-year-old Brahman breed bovine is reported, which was submitted by presenting a mass in the third eyelid of the left eye which obstructed vision. Histopathological analysis of the submitted sample shows a well-differentiated squamous cell carcinoma with no evidence of lymphovascular invasion. The therapeutic management consisted of exenteration to avoid recurrences, for which the patient's evolution was satisfactory without causing problems in his productive performance. It has been described that a possible risk factor is related to permanent exposure to sunlight that affects the replication of DNA in cells and induces tumor processes. While it is true; in cattle breeding systems where females spend most of the time grazing and are exposed to ultraviolet radiation, this would explain the reason for the presentation of this neoplasm in this type of patient. In this sense, it is essential to pay attention and monitor abnormalities that may occur in cattle, whether Zebu or Taurine. [ABSTRACT FROM AUTHOR]

Introduction: Ocular prosthesis is an artificial means with functional and cosmetic ends that facilitates the physical, psychic and social rehabilitation of patients with eyes defects. Objective: To describe the evolution of patients with ocular prosthesis according to infection signs in the rehabilitated ocular cavities, associated risk factors, as well as modifications in the form of the cavity and/or in the ocular prosthesis. Methods: An observational, longitudinal and prospective study of 74 patients suffering from eye defects that received prosthetist treatment from 2018 to 2019 in the oral maxillofacial Rehabilitation Clinic was carried out in Santiago de Cuba, who were evaluated through a survey and a clinical exam in three moments during a year of evolution. To establish the association between variables, the Pearson chi-square and Fisher exact tests were used with the fulfillment of suppositions. Results: Of the 222 exams made to the rehabilitated ocular cavities, 31 revealed the presence of secretions in 23 patients, with recurrence in 8 of them; this clinical sign became evident in a similar way to the hypercoloring of the conjunctiva as for the moment of the finding and the age group affected, with higher percentages at the year of evolution and a higher incidence in the patients of 60 years and over. Also, an association statistically significant of the daily hygiene of the cavity and prosthesis variables with the existence of secretions was verified, for a confidence interval of 95 %. Conclusions: The advantage of the ocular cavity and prosthesis weekly personal cleanliness was demonstrated, because with it the frequency of the inflammatory and infectious signs of the mucous is reduced, what should be strictly observed in elderly, who are the most affected.
