RESUMEN

PURPOSE: To describe the epidemiology, clinical features, and classification of uveitis in a large cohort of Colombian patients. METHODS: Data were collected from seven ophthalmological referral centers in the four main cities in Colombia. The study included patients with a confirmed diagnosis of uveitis from January 2010 to December 2022. Information on demographics, ophthalmic examination findings, uveitis classification, and etiology was recorded. RESULTS: The study reviewed 3,404 clinical records of patients with uveitis. The mean age at diagnosis was 41.1 (SD 19.0) years, and 54.2% of the patients were female. Overall, 1,341(39.4%) were infectious, 626 (18.4%) non-infectious, and four masquerade syndromes (0.1%). The most common types of uveitis were unilateral (66.7%), acute (48.3%), and non-granulomatous (83%). Anterior uveitis was the most common anatomical localization (49.5%), followed by posterior uveitis (22.9%), panuveitis (22.3%), and intermediate uveitis (5.2%). A diagnosis was established in 3,252 (95.5%) cases; idiopathic was the most common cause (27.7%), followed by toxoplasmosis (25.3%) and virus-associated uveitis (6.4%). The age group between 30 and 50 exhibited the highest frequency of uveitis. CONCLUSION: This multicenter study comprehensively describes uveitis characteristics in Colombian patients, providing valuable insights into its demographic and clinical features. The study findings emphasize the need to continue updating the changing patterns of uveitis to improve diagnosis and treatment strategies for diseases associated with intraocular inflammation.

RESUMEN

INTRODUCTION: Glaucoma is a neurodegenerative disease characterized by the loss of retinal ganglion cells. Recent research suggests immunological changes such as cytokine imbalance may affect its pathophysiology. This implies that immunomodulation, like that of mesenchymal cells, could be a potential therapeutic avenue for this disease. However, the effects of intravitreal injections of human Wharton's jelly-derived mesenchymal stromal cells (hWJ-MSCs) on intraocular immune response have not been assessed in ocular hypertension (OH) models. METHODS: We explored this by measuring cytokine levels and expression of other markers, such as glial fibrillary acidic protein (GFAP) and T cells, in 15 randomly divided New Zealand rabbits: G1: OH, G2: hWJ-MSCs, and G3: OH+hWJ-MSCs. We analyzed the aqueous humor (IL-6, IL-8, and TNF-α) and vitreous humor (IFN-γ, IL-10, and TGF-ß) using ELISA and flow cytometry (cell populations), as well as TCD3+, TCD3+/TCD4+, and TCD3+/TCD8+ lymphocytes, and GFAP in the retina and optic nerve through immunohistochemistry. RESULTS: We found a decrease in TNF-α, IL-6, IFN-γ, IL-10, and IL-8 in G3 compared to G1 and an increase in TGF-ß in both G2 and G3. TCD3+ retinal infiltration in all groups was primarily TCD8+ rather than TCD4+ cells, and strong GFAP expression was observed in both the retina and optic nerves in all groups. CONCLUSION: Our results suggest that cellular and humoral immune responses may play a role in glaucomatous optic neuropathy and that intravitreal hWJ-MSCs can induce an immunosuppressive environment by inhibiting proinflammatory cytokines and enhancing regulatory cytokines.

RESUMEN

Objective: Visual acuity (VA) testing is crucial for early intervention in cases of visual impairment, especially in rural health care. This study aimed to determine the potential of a web-based VA test (PocDoc) in addressing the unique health care needs of rural areas through the comparison in its effectiveness against the conventional VA test in identifying visual impairment among an Indian rural population. Methods: Prospective comparative study conducted in December 2022 at a tertiary referral eye care center in central India. We evaluated all patients with the PocDoc VA tests using three device types, and the conventional VA test. Bland-Altman plot (BAP) compared PocDoc and conventional VA tests. Fisher's exact tests evaluated associations between categorical parameters. Kruskal-Wallis tests followed by post hoc Dunn's tests identified association between categorical parameters and numerical parameters. Results: We evaluated 428 patients (792 measurements of VA) with mean age 36.7 (±23.3) years. PocDoc resulted in slightly worse VA scores (mean logMAR: 0.345) than conventional (mean logMAR: 0.315). Correlation coefficient between the conventional and PocDoc logMAR VA values was rho = 0.845 and rho2 = 0.7133 (p = 6.617 × 10-215; adjusted p = 2.205 × 10-214). Most data points fell within the interchangeable range of ±0.32 on BAP. Difference between the two methods increased with higher logMAR values, indicating poorer agreement for worse VA scores. Conclusions: Identifying and addressing the unique health care needs of rural populations is critical, including access to appropriate and effective VA testing methods. Validating and improving VA testing methods can ensure early intervention and improve the quality of life for individuals with visual impairment.

RESUMEN

PURPOSE: To describe the distribution patterns and clinical characteristics of patients diagnosed with uveitis at a specialized uveitis center in Bogotá, Colombia, from 2013 to 2021 and compare these patterns with the previously reported between 1996 and 2006. METHODS: We performed an observational descriptive cross-sectional study systematically reviewing clinical records of patients attending between 2013 and 2021. Data were analyzed and compared with previous reports. RESULTS: Of the 489 patients with uveitis, 310 were females (63.4%). The mean age of onset was 38.7, with a range between 1 and 83 years. Bilateral (52.8%), anterior (45.8%), non-granulomatous (90.8%), and recurrent (47.6%) were the most common types of uveitis found in our population sample. The most common cause of uveitis in this study was idiopathic, followed by toxoplasmosis and HLA-B27 + associated uveitis, which differs from the previous Colombian study where ocular toxoplasmosis was the most frequent cause. This highlights a significant shift from infectious etiologies to more immune-mediated processes as the cause of uveitis in Colombia nowadays. CONCLUSION: The results of this study provide a comparison between the clinical patterns of presentation of uveitis from 1996 to 2006 and the patterns observed from 2013 to 2021, enhancing awareness about the changing dynamics of uveitis in Colombia to guide a better understanding of the diagnosis, classification, and correlation with other systemic conditions of the disease.

RESUMEN

BACKGROUND: To describe the ocular features of a cohort of children with Down Syndrome (DS) in Bogotá, Colombia. METHODS: We performed a cross-sectional study, evaluating 67 children with DS. A pediatric ophthalmologist performed a complete optometric and ophthalmological evaluation of each child, including visual acuity, ocular alignment, external eye examination, biomicroscopy, auto-refractometry, retinoscope in cycloplegia, and fundus examination. Results were reported as frequency distribution tables with percentages for categorical variables and means and standard deviation or median and interquartile ranges for continuous variables, according to their distribution. We used the Chi-square test or Fisher's exact test for categorical variables and ANOVA or Kruskal-Wallis for continuous variables when indicated. RESULTS: A total of 134 eyes from 67 children were evaluated. Males represented 50.7%. The children's age ranged from 8-16 years, with a mean of 12.3 (SD 2.30). The most frequent refractive diagnosis per eye was hyperopia (47%), followed by myopia (32.1%) and mixed astigmatism (18.7%). The most frequent ocular manifestations were oblique fissure (89.6%), followed by amblyopia (54.5%) and lens opacity (39.4%). Female sex was associated with strabismus (P = 0.009) and amblyopia (P = 0.048). CONCLUSION: Our cohort had a high prevalence of disregarded ophthalmological manifestations. Some of these manifestations, such as amblyopia, can be irreversible and severely affect the neurodevelopment of DS children. Therefore, ophthalmologists and optometrists should be aware of the visual and ocular affection of children with DS to assess and provide appropriate management. This awareness could improve rehabilitation outcomes for these children.

RESUMEN

PURPOSE: This study aims to describe the clinical characteristics of scleritis in a large cohort of Colombian patients and identify factors associated with the clinical presentation. METHODS: Retrospective case series of patients with scleritis from 2015 to 2020. Clinical records were obtained from seven uveitis referral centers in Colombia. Patients with a diagnosis of episcleritis were excluded. RESULTS: We evaluated 389 patients with scleritis (509 eyes). There was a female predominance (75.6%) with a mean age of 51 ± 15 years. Most cases were noninfectious (94.8%) and unilateral (69.2%). The most frequent type of inflammation was diffuse anterior scleritis (41.7%), followed by nodular scleritis (31.9%) and necrotizing scleritis (12.3%). Systemic autoimmune diseases were found in 41.3% of patients, the most common being rheumatoid arthritis (18.5%) and granulomatosis with polyangiitis (5.9%). Polyautoimmunity was found in 10.4% of those with a systemic autoimmune disease. The most frequent treatment was systemic steroids (50.9%), followed by systemic NSAIDs (32.4%). Steroid-sparing immunosuppression was required in 49.1% of patients. Systemic autoimmune diseases were more common in patients with necrotizing scleritis and those older than 40 years of age. Best-corrected visual acuity of 20/80 or worse at presentation was more common in necrotizing scleritis and subjects with associated uveitis, ocular hypertension, or who were over 40 years of age. CONCLUSIONS: This is the first study in Colombia and the largest in Latin America describing the clinical characteristics and presentation patterns of scleritis. The most common presentation was in females, with unilateral, anterior diffuse noninfectious scleritis. Systemic autoimmune diseases and polyautoimmunity were frequent, as was the need for steroid-sparing immunosuppression. Age over 40 and necrotizing scleritis were associated with higher odds of having a systemic autoimmune disease and worse visual acuity at presentation.

RESUMEN

BACKGROUND: This study aimed to report a case of bilateral anterior non-granulomatous chronic non-infectious uveitis associated with isolated nail psoriasis without articular involvement. CASE PRESENTATION: A 55-year-old man with a history of open-angle glaucoma was referred to our uveitis and ocular immunology center with intraocular inflammation concordant with chronic non-infectious bilateral anterior non-granulomatous uveitis. At presentation, he had moderate inflammation in the anterior chamber bilaterally and lesions characteristic of nail psoriasis. Nail psoriasis was later confirmed by nail ultrasonography performed by a radiologist who specialized in psoriasis. Appropriate clinical and paraclinical assessments were conducted, ruling out all other possible causes of uveitis. The patient required dual systemic immunomodulatory therapy with methotrexate and adalimumab, topical anti-inflammatory drugs (steroidal and non-steroidal), and anti-glaucoma therapy to achieve satisfactory inflammatory and ocular pressure control. DISCUSSION AND CONCLUSIONS: This is the first report of non-infectious uveitis associated with nail compromise in a patient without other manifestations of psoriasis. Despite reports on the relationship between psoriatic disease and uveitis, there is insufficient information on clinical phenotypes associated with uveitis that could lead to later diagnosis and treatment of associated intraocular inflammation. Clinicians should be aware of all subtypes of psoriasis that increases a risk of developing uveitis in these patients.

RESUMEN

INTRODUCTION: Macular diseases are major contributors to visual impairment and blindness worldwide. This study introduces PocDoc, a digital version of the conventional Amsler grid, aimed at enhancing the screening and monitoring of macular diseases. We conducted a comprehensive evaluation to compare the effectiveness of PocDoc against the conventional method. METHODS: Our comparative analysis involved two distinct phases. Initially, we assessed the capability of both PocDoc and the conventional method in detecting central visual field abnormalities. This phase included a cohort of 72 healthy and 155 eyes affected by various conditions such as age-related macular degeneration (AMD), uveitis, polypoidal choroidal vasculopathy (PCV), and macular telangiectasia. We primarily focused on the area of compromise and observed the correlation between the results obtained from both methods, measuring their concordance using a correlation coefficient. In the second phase, we evaluated the accuracy of both methods in diagnosing AMD. This involved a group of 127 eyes, including 70 healthy and 57 AMD-affected eyes. We determined the sensitivity, specificity, and overall accuracy of each method in diagnosing AMD. RESULTS: In the initial phase, both PocDoc and the conventional Amsler grid demonstrated a high correlation in detecting central visual field defects across various macular diseases (correlation coefficient > 0.9). In the second phase, focused on AMD diagnosis, PocDoc showed a sensitivity of 50%, specificity of 100%, and an overall accuracy of 78%. Comparatively, the conventional method exhibited a sensitivity of 49%, specificity of 100%, and accuracy of 77%. CONCLUSION: PocDoc's digital Amsler grid exhibits comparable effectiveness to the conventional method in both detecting visual field abnormalities across a range of macular diseases and specifically in the diagnosis of AMD. The high correlation in results, combined with the digital advantages of PocDoc, such as ease of use and potential for telemedicine applications, suggests its viability as a valuable tool in the screening and monitoring of macular diseases.

RESUMEN

INTRODUCTION: The efficacy of diagnostic and monitoring tools in ophthalmology is significantly influenced by patient engagement levels. This presents a notable challenge, especially in the context of developing tools designed for telemedicine applications. Ensuring consistent patient engagement is therefore crucial for the accurate and reliable utilization of these technologies. This study assesses patient perceptions and experiences after using a purpose-built web application, called PocDoc. METHODS: A cross-sectional questionnaire-based survey was conducted among 440 patients recruited from general and specialist eye clinics between March 2022 and October 2023, both before and after using the PocDoc app. RESULTS: Pre-test findings revealed that 86.8% of patients thought that a remote eye monitoring application would have use, while 70.9% anticipated frequent usage. Only 16.4% found it overly complex, and 55.2% perceived it as easy to use. Additionally, 34.5% foresaw the need for technical support, while 72.5% believed they would quickly grasp its use. In the post-test questionnaire, 63.3% of patients still expressed intent for frequent PocDoc usage. The perception of complexity decreased to 20.4%, with 79.3% finding it easy to use. The belief in the need for technical support decreased to 36.5%, while 89.9% felt confident in mastering the application quickly. Moreover, 77.3% found the application's functions well-integrated, and 64.6% were very confident using PocDoc. CONCLUSIONS: Results suggest patient receptivity to web-based applications, confirming their viability for specific patient groups. Overall, our study contributes to the growing body of evidence indicating that greater exposure to digital health tools can significantly influence patient acceptance and perceived ease of use, an insight that has important implications for the implementation and design of these technologies in clinical settings.

RESUMEN

This retrospective case series aims to describe the ophthalmic manifestations of the Monkeypox virus infection in seven patients evaluated in two countries of South America (Colombia and Brazil). Two had skin lesions in the eyelid, and five had conjunctivitis. None had intraocular involvement. Three of seven patients had a history of Human Immunodeficiency Virus infection, and all patients had lesions in the genital region, suggesting sexual-contact transmission. In 6 of 7 cases, conjunctival RT-PCR was positive for the Monkeypox virus, including one case without conjunctival vesicles. In all cases, lesions resolved without complications, and just two required antiviral treatment. All patients demonstrated improvement without complications. RT-PCR positivity in conjunctiva demonstrated the presence of the Monkeypox virus, suggesting that ocular-mediated transmission could be plausible. Ophthalmologists should be aware of this ophthalmic manifestation.

RESUMEN

PURPOSE: To describe the differences between de novo uveitis in elderly patients (≥60 years of age) and younger patients (< 60 years of age) in Colombia. METHODS: Observational, analytic, cross-sectional study. RESULTS: In the elderly group, idiopathic was the most common type of uveitis, followed by immune-mediated and infectious uveitis.No masquerade syndromes were diagnosed. Elderly patients had worse average visual acuities than young. Significant differences between both groups were observed in corneal edema, macular edema, cataract, glaucoma, and epiretinal membrane. Additionally, there were differences in the drugs used, such as topical hypotensive drugs, ocular lubricants, topical steroids, methotrexate, hydroxychloroquine, and adalimumab. CONCLUSION: The present study demonstrated significant differences between elderly and young Colombian patients with de novo uveitis. The ophthalmologists should be aware of these patterns of presentation, which would help reach an adequate diagnosis and prevent complications based on the characteristics of each group.

RESUMEN

We aimed to compare the concordance of information extracted and the time taken between a large language model (OpenAI's GPT-3.5 Turbo via API) against conventional human extraction methods in retrieving information from scientific articles on diabetic retinopathy (DR). The extraction was done using GPT3.5 Turbo as of October 2023. OpenAI's GPT-3.5 Turbo significantly reduced the time taken for extraction. Concordance was highest at 100% for the extraction of the country of study, 64.7% for significant risk factors of DR, 47.1% for exclusion and inclusion criteria, and lastly 41.2% for odds ratio (OR) and 95% confidence interval (CI). The concordance levels seemed to indicate the complexity associated with each prompt. This suggests that OpenAI's GPT-3.5 Turbo may be adopted to extract simple information that is easily located in the text, leaving more complex information to be extracted by the researcher. It is crucial to note that the foundation model is constantly improving significantly with new versions being released quickly. Subsequent work can focus on retrieval-augmented generation (RAG), embedding, chunking PDF into useful sections, and prompting to improve the accuracy of extraction.

RESUMEN

Infectious uveitis is a major global cause of vision impairment. Despite the eye's immune privilege, afforded by the blood-ocular barrier that restricts microbial entry, several pathogens such as bacteria, viruses, fungi, and parasites can still infiltrate and cause ocular infections and complications. Clinicians often encounter significant challenges in treating infectious uveitis due to limited or ineffective treatment options. Modern molecular techniques and imaging can aid in diagnosing and assessing intraocular infections. Various antimicrobial therapies exist, spanning topical and systemic treatments, but these are constrained by issues like drug concentration, penetration, effective duration, toxicity, and side effects. Treatment approaches also differ based on the infection's etiology. This review provides recent updates on antimicrobial therapies from a clinical perspective, covering topical, systemic, and regional treatments for infectious uveitis.

RESUMEN

OBJECTIVES: To describe the clinical features of patients diagnosed with uveitic glaucoma (UG) and ocular hypertension secondary to uveitis (OHT-SU). METHODS: A multicentric cross-sectional study using medical records of patients with uveitis between 2013 and 2021. Uveitis and glaucoma specialists examined all patients. Variables were analyzed using the chi-square or Fisher's exact test for categorical variables. Additionally, t test, Mann-Whitney, and Kruskal-Wallis variance analysis were used for continuous variables. Finally, a Kaplan-Meier survival analysis for UG and OHT-SU development over time was done. RESULTS: Of the 660 clinical records reviewed of patients with uveitis, 191 (28.9%) had OHT-SU in at least one visit, and 108 (16.4%) of them developed UG. In all ages, females were more affected than males. Anterior uveitis was the main anatomic localisation, and non-granulomatous, recurrent, and inactive uveitis were the most frequent clinical features. The mean final visual acuity was 0.3 (0.0-1.0) LogMAR. Also, 95.8% of the patients had additional sequelae related to uveitis regardless of UG and OHT-SU. Interestingly, males had earlier affection, with statistical significance in OHT for adults (P = 0.036) and UG for children (P = 0.04). Of all patients, 81.1% received topical hypotensive treatment and 29.8% required a surgical procedure. CONCLUSIONS: UG and OHT-SU are common complications of uveitis in the Colombian population. These sight-threatening conditions were more common and appeared sooner in men at any age. Our results suggest that earlier and more aggressive treatment with topical hypotensive agents could positively influence the visual outcomes and the requirement of surgical procedures.

RESUMEN

Assessing anterior chamber inflammation is highly subjective and challenging. Although various grading systems attempt to offer objectivity and standardization, the clinical assessment has high interobserver variability. Traditional techniques, such as laser flare meter and fluorophotometry, are not widely used since they are time-consuming. With the development of optical coherence tomography with high sensitivity, direct imaging offers an excellent alternative to assess objectively inflammation with the potential for automated analysis. We describe various anterior chamber inflammation grading methods and discuss their utility, advantages, and disadvantages.

RESUMEN

PURPOSE: To estimate the prevalence and demographic characteristics of uncorrected refractive errors (URE) in people who attended eye care consultations in Colombia between 2015 and 2019, using the National Health Registry data. METHODS: We identified ICD codes for myopia (H-52.1), degenerative myopia (H-44.2), hyperopia (H-52.0), and astigmatism (H-52.2) from the Integrated Social Protection Information System. Crude prevalence rates by age and sex were calculated for the population attending eye care services during these years. Additionally, we developed a standardized morbidity map across county departments. RESULTS: In Colombia, the prevalence of URE among eye care consultations was 30.26%, increasing from 30.39% in 2015 to 35.14% in 2019. Of the 1,579,778 cases analyzed, 60.9% were females. Astigmatism emerged as the most prevalent URE, predominantly seen in individuals under 40 years old. Myopia showed the highest prevalence in the 10-30 age group, whereas hyperopia was most prevalent in the first decade of life. Geographically, the Andean region recorded most of URE cases, while more remote areas have seen a rising morbidity risk in recent years. CONCLUSIONS: The rising trend of URE in Colombia and its demographic and geographical variations underscores the urgent need for health professionals and government authorities to acknowledge and address this issue. This study provides crucial insights into the refractive error landscape across the country, highlighting the necessity for prevention programs specifically designed to cater to the country's unique needs.

RESUMEN

Background and Aim: Stem cell therapy is considered a promising treatment for several neurodegenerative diseases. However, there are very few studies on the use of this therapy in glaucoma models. By detecting the changes produced by glaucoma early, cell therapy could help prevent the events that lead to blindness. In this study, early changes in the optic nerve head (ONH) as detected by optical coherence tomography (OCT) after the application of human Wharton's jelly-derived mesenchymal stromal cells (hWJ-MSCs) in an experimental model of ocular hypertension (OH) were evaluated. Materials and Methods: Fifteen New Zealand rabbits were randomly divided into the following three groups: G1: OH, G2: hWJ-MSCs, and G3: OH + hWJ-MSCs. An OH model was constructed, and the intraocular pressure (IOP) was measured regularly. At week 7, 105/100 µL hWJ-MSCs were intravitreally injected. Retinography and OCT were used to evaluate structural changes in ONH. Results: IOP increased significantly in G1 and G3 from week 3 onward. Retinography revealed more significant optic nerve changes, that is, papillary asymmetry suggestive of optic nerve excavation, vascular alterations, and irregular hypopigmentation peripheral to the optic disk margin, in G1 compared with G3. OH locates the hWJ-MSCs solution in the vitreous in front of the optic nerve. OCT revealed retinal nerve fiber layer (RNFL) reduction in all groups, reduced optic cup volume in G2 and G3 between weeks 1 and 9, and significant ganglion cell layer thickness reduction in G1 and a slight increase in G3. Conclusion: Intravitreal hWJ-MSCs injection produced changes in optic cup volume, which were detected early on by OCT; however, RNFL could not be restored in this OH model.

RESUMEN

The aim of this perspective is to promote the theory of salutogenesis as a novel approach to addressing ophthalmologic inflammatory conditions, illustrating several concepts in which it is based upon and how they can be applied to medical practice. This theory can better contextualize why patients with similar demographics and exposures are not uniform in their clinical presentations. Stressors in daily life can contribute to a state of ill-health and there are various factors that help alleviate their negative impact. These alleviating factors are significantly impaired in people with poor vision, one of the most common presentations of ophthalmologic conditions. Salutogenic principles can guide the treatment of eye conditions to be more respectful of patient autonomy amidst shifting expectations of the doctor-patient relationship. Being able to take ownership of their health and feeling that their cultural beliefs were considered improves compliance and subsequently gives more optimal outcomes. Population-level policy interventions could also utilize salutogenic principles to identify previously overlooked domains that can be addressed. We identified several papers about salutogenesis in an ophthalmological context and acknowledged the relatively few studies on this topic at present and offer directions in which we can explore further in subsequent studies.

RESUMEN

PURPOSE: To evaluate rural community-based eye care models from the perspective of community ophthalmology experts and suggest sustainable technological solutions for enhancing rural eye care delivery. METHODS: A semi-structured descriptive survey, using close-ended and open-ended questions, was administered to the experts in community ophthalmology sourced through purposive sampling. The survey was self-administered and was facilitated through online platforms or in-person meetings. Uniform questions were presented to all participants, irrespective of their roles. RESULTS: Surveyed participants (n = 22 with 15 from India and 7 from Nepal) in high-volume tertiary eye hospitals faced challenges with resources and rural outreach. Participants had mixed satisfaction with pre-operative screening and theatre resources. Delayed presentations and inexperienced surgeons contributed to the surgery complications. Barriers to rural eye care included resource scarcity, funding disparities, and limited infrastructure. In rural/peri-urban areas 87% of participants agreed with providing primary eye care services, with more than 60% of the experts not in agreement with the makeshift center model of eye care delivery. Key components for an effective eye care model are sustainability, accessibility, affordability, and quality. These can be bolstered through a healthcare management platform and a human-chain supply distribution system. CONCLUSION: Tailored interventions are crucial for rural eye care, emphasizing the need for stronger human resources, optimized funding, and community awareness. Addressing challenges pertinent to delayed presentation and surgical training is vital to minimizing complications, especially with advanced cataracts. Enhancements in rural eye care demand a comprehensive approach prioritizing accessibility, affordability, and consistent quality.
