RESUMEN
PURPOSE: To investigate whether intravitreal antiviral injection (IAI) during vitrectomy reduces the postsurgical retinal detachment (RD) rate and improves the visual prognosis of patients with acute retinal necrosis (ARN). METHODS: This retrospective cohort study included ARN patients treated at a tertiary hospital between January 2013 and December 2020. Patients who underwent pars plana vitrectomy (PPV) alone or combined with intraoperative IAI were classified in PPV-only group and PPV + IAI group, respectively. The incidence of postsurgical RD and the best corrected visual acuity (BCVA) between the groups was compared. A multivariate Cox hazard analysis was employed to explore the risk factors of postsurgical RD. A multivariate logistic regression analysis was applied to assess the impact of intraoperative IAI on preventing severe vision loss (SVL). RESULTS: Fifty-seven eyes with ARN with a median follow-up of 18.5 months were included in the study. There was no significant association between intraoperative IAI during vitrectomy and a reduced risk of postsurgical RD (hazard ratio [HR], 2.65; 95% CI, 0.71-9.89) or SVL at the 6-month follow-up visit (odds ratio [OR], 0.92; 95% confidence interval [CI], 0.25-3.35). Better baseline best-corrected visual acuity (BCVA) was identified to associate with a higher risk of postsurgical RD (HR, 0.33; 95% CI, 0.14-0.81) and a lower risk of SVL at 6 months (OR, 2.28; 95% CI, 1.10-4.89). CONCLUSION: We did not observe a significant effect of intraoperative IAI on the anatomic and visual outcomes of ARN patients in this study. Intraoperative IAI may not be a necessary treatment option for ARN patients who receive vitrectomy.

PURPOSE: To study the clinical features, causative factors and treatment outcomes in patients with infectious scleritis seen in India. METHODS: A retrospective study of all patients examined at a tertiary care center between August 2012 and March 2021. RESULTS: Forty-five patients (45 eyes; mean age 52.7 ± 17.5 years) were included in the study. The mean duration of symptoms was 3.1 ± 4.4 months. Inciting factors were found in 53.3% (injury: 33.3%; ocular surgery: 20.0%). The scleritis was predominantly anterior (97.8%), with multiple lesions in 40.0%, a solitary lesion in 31.1%, and diffuse in 28.9%. Associated features included uveitis (51.1%), keratitis (37.8%), hypopyon (15.6%), and endophthalmitis (6.7%). Causative organisms included bacteria (53.3%), fungi (35.6%), and presumed herpes virus (11.1%). All patients were treated with antimicrobial agents along with systemic corticosteroids where indicated. Surgical treatment included scleral debridement (37.8%), patch grafts (4.4%), and penetrating keratoplasty (2.2%). Complete resolution of scleritis was seen in 86.7%, with a mean duration of therapy of 2.9 ± 2.5 months. The mean follow-up was 8.3 ± 14.3 months. 51.1% of patients lost functional vision (<6/60). Causes of decreased vision included corneal scar, cataract, macular scar, glaucomatous optic atrophy, and phthisis bulbi. On bivariate analysis, poor visual acuity at presentation was associated with a worse visual outcome (p = 0.02). Other risk factors included necrotizing scleritis, multifocal scleritis, the presence of keratitis and uveitis. CONCLUSION: In our study, infectious scleritis resulted from bacterial and fungal infections. The scleritis resolved in most subjects, however, vision loss was frequent due to infection-related complications.
RESUMEN
BACKGROUND: Preoperative prediction of visual outcomes following pituitary adenoma surgery is challenging yet crucial for clinical decision-making. We aimed to develop models using radiomics from multiparametric MRI to predict postoperative visual outcomes. METHODS: A cohort of 152 patients with pituitary adenoma was retrospectively enrolled and divided into recovery and non-recovery groups based on visual examinations performed six months after surgery. Radiomic features of the optic chiasm were extracted from preoperative T1-weighted imaging (T1WI), T2-weighted imaging (T2WI), and contrast-enhanced T1-weighted imaging (T1CE). Predictive models were constructed using the least absolute shrinkage and selection operator wrapped with a support vector machine through five-fold cross-validation in the development cohort and evaluated in an independent test cohort. Model performance was evaluated using the area under the curve (AUC), accuracy, sensitivity, and specificity. RESULTS: Four models were established based on radiomic features selected from individual or combined sequences. The AUC values of the models based on T1WI, T2WI and T1CE were 0.784, 0.724, 0.822 in the development cohort, and 0.767, 0.763, 0.794 in the independent test cohort. The multiparametric model demonstrated superior performance among the four models, with AUC of 0.851, accuracy of 0.832. sensitivity of 0.700, specificity of 0.910 in the development cohort, and AUC of 0.847, accuracy of 0.800, sensitivity of 0.882 and specificity of 0.750 in the independent test cohort. CONCLUSION: The multiparametric model utilizing radiomics of optic chiasm outperformed single-sequence models in predicting postoperative visual recovery in patients with pituitary adenoma, serving as a novel approach for enhancing personalized treatment strategies.
RESUMEN
BACKGROUND: The present study compares the anatomical and functional outcomes (best-corrected visual acuity (BCVA) and central macular thickness (CMT)) among membrane peeling with or without SF6 tamponade in patients with epiretinal membrane. METHODS: We retrospectively reviewed patients diagnosed with macular pucker who underwent pars plana vitrectomy and membrane peeling in a tertiary center in Taiwan from January 2021 to December 2022. Subjects were categorized into with or without SF6 tamponade groups (SF6 group and BSS group). Postoperative intraocular pressure and complications were documented. Logistic regression analyses were performed to identify the prognostic factors during follow-up. RESULTS: A total of 89 eyes were enrolled, including 34 eyes in the BSS group and 55 eyes in the SF6 group. The mean age was 66 years old, and a female predilection was demonstrated. Both groups possessed statistically significant improvement in BCVA and CMT after the operation. There was no significant difference in CMT between the groups at any time of observation, yet we observed significant differences in baseline BCVA and BCVA at last follow-up among the two groups. Both groups yielded an approximate enhancement of LogMAR 0.3 in BCVA postoperatively. There was no significant difference noted in postoperative IOP between the two groups. CONCLUSION: Membrane peeling with or without SF6 tamponade yields comparable outcomes anatomically and functionally. This may indicate that SF6 tamponade for idiopathic macular pucker surgery may not provide extra benefit, and therefore warrants reconsideration as standard procedure.
RESUMEN
Background: The path of rehabilitation of an eye after open globe injury (OGI) may require multiple additional secondary surgeries after the initial repair. Although much has been studied regarding the outcomes of secondary surgeries after open globe repair, it can be challenging to understand the possible implications of the surgical rehabilitative process. This retrospective study considers the benefits of the required additional secondary surgeries for a consecutive series of OGI patients. Methods: OGI patients who had at least one additional surgery after the initial open globe repair (OGR) were studied retrospectively. Additional inclusion criteria included: follow up of at least 12 months since the initial injury and at least 3 months since their most recent surgery, and no additional planned interventions. Preoperative visual acuity was compared to final visual acuity. Additionally, the odds of achieving ambulatory vision (≥20/800) and reading vision (≥20/40) were calculated after each indicated consecutive surgery. Results: A cohort of 74 eyes from 73 patients met our inclusion criteria. These patients underwent a mean of two additional surgeries. The mean logMAR VA improved from 2.3 (HM) at presentation to 1.4 (20/150), or a 9-line Snellen equivalent improvement. Upon reaching their final visit status, 50% of patients had achieved ambulatory vision and 30% of patients had achieved reading vision. The odds of achieving ambulatory vision after completion of all the rehabilitative surgical process compared to the vision prior to the secondary rehabilitative surgery were higher (OR: 19.1, 95% CI: 7.9 - 30.4, p = 0.0008) as were the odds of achieving reading vision (OR: 4.6, 95% CI: 0.2 - 9.0, p = 0.04). With subsequent second, third, and fourth additional surgeries, the odds of achieving either ambulatory or reading vision at the final visit compared to their preoperative visual acuities were not significant (p > 0.05) but the visual acuity continued to trend toward visual improvement. Conclusion: Approximately 50% of individuals who required additional surgery at UMN achieved ambulatory vision and 30% achieved reading vision. The odds of visual improvement through the surgical rehabilitative process were very high, with the greatest gains generally achieved after the first surgery.
RESUMEN
The purpose of this study was to examine how demographics, etiology, and clinical examination findings are related to visual outcomes in subjects with open globe injury (OGI) across a large and generalizable sample. A retrospective cohort analysis was performed using data collected from the electronic medical records of four tertiary university centers for subjects with OGI presenting from 2018 to 2021. Demographic information, injury mechanisms, clinical exam findings, visual acuity (VA) at presentation and most recent follow-up were recorded. In subjects with bilateral OGIs, only right eyes were included. A modified ocular trauma score (OTS) using presenting VA, the presence of perforating injury, OGI, and afferent pupillary defect was calculated. The risk of subjects' demographic characteristics, ocular trauma etiology, clinical findings and modified OTS on the presence of monocular blindness at follow-up were assessed using univariable and multivariable regression models. 1426 eyes were identified. The mean age was 48.3 years (SD: ± 22.4 years) and the majority of subjects were men (N = 1069, 75.0%). Univariable analysis demonstrated that subjects of Black race were 66% (OR: 1.66 [1.25-2.20]; P < 0.001) more likely to have monocular blindness relative to White race at follow-up. OTS Class 1 was the strongest predictor of blindness (OR: 38.35 [21.33-68.93]; P < 0.001). Based on multivariable analysis, lower OTS category (OTS Class 1 OR: 23.88 [16.44-45.85]; P < 0.001) moderately predicted visual outcomes (R2 = 0.275, P < 0.001). OGI has many risks of poor visual outcome across patient groups that vary by demographic category, mechanism of injury, and clinical presentation. Our findings validate that a modified OTS remains a strong predictor of visual prognosis following OGI in a large and generalizable sample.

BACKGROUND: Proliferative diabetic retinopathy is a leading cause of blindness among people with diabetes. The study aimed to assess the clinical characteristics of proliferative diabetic retinopathy and outcome of pars plana vitrectomy in Proliferative diabetic retinopathy. METHODS: A prospective study was conducted from September 2019 to December 2021 among consecutive cases of proliferative diabetic retinopathy who underwent pars plana vitrectomy at a tertiary eye care center. Study was conducted after ethical approval from Institutional Review Committee. Detailed systemic and ocular history, visual acuity, ocular findings under mydriasis, surgical procedures, and outcome following pars plana vitrectomy were recorded. Cases were followed up regularly until one year after the pars plana vitrectomy. RESULTS: Total of 83 cases (89 eyes) of proliferative diabetic retinopathy were enrolled in the study. The mean age was 53 years ±9.7 SD, ranging from 26 years to 72 years. Males comprised of 62.7% cases. Type two diabetes comprised of 94% of cases. Indications for pars plana vitrectomy were; mixed vitreous hemorrhage and tractional retinal detachment (38.2%), non-clearing vitreous hemorrhage (38.1%), and tractional retinal detachment only (24.7%). Pre-operative intra-vitreal anti-vascular endothelial growth factor was given in 78.65% eyes and pan retinal photocoagulation in 58.42% eyes. The anatomical success was achieved in 95.5% eyes, visual improvement in 68.54%, static in 14.6% and worsened in 16.86% of eyes. About 15.7% of eyes had some form of post- operative complications. CONCLUSIONS: Vitreous hemorrhage with tractional retinal detachment, persistent vitreous hemorrhage and tractional retinal detachment involving macula were the common indication of pars plana vitrectomy among cases of Proliferative diabetic retinopathy. Anatomical success and visual acuity improvement can be achieved in majority of the eyes following PPV in Proliferative diabetic retinopathy.

OBJECTIVE: This study compared the effectiveness of the endoscopic endonasal approach (EEA) with the conventional transcranial approach (TCA) for treating tuberculum sellae meningiomas (TSMs), aiming to identify the superior surgical method and the risk factors affecting outcomes. METHODS: Patients treated for TSM from 1998 to 2023 at our institution were retrospectively analyzed, evaluating patient characteristics, tumor features, outcomes, and complications. A novel grading system for preoperative evaluation of TSMs was proposed. RESULTS: Among 49 patients, 26 underwent EEA and 23 underwent TCA. The maximum diameters were comparable between the groups (mean 22 mm vs. 23 mm). Gross total resection rates were 62% for EEA and 70% for TCA, showing no significant difference. However, postsurgical visual improvement was significantly higher in the EEA group compared with the TCA group (77% vs. 44%; P = 0.020), with fewer complications in the EEA group (8% vs. 35%; P = 0.032). CONCLUSIONS: EEA is a safe and effective treatment approach for small to medium TSMs, with outcomes comparable to TCA in terms of resection but superior in visual improvement and fewer complications. Selection of surgical approach should consider patient and tumor characteristics as well as surgeon experience.
RESUMEN
Purpose: To investigate the long-term visual outcome and their determinants after an operation in Thai pituitary adenoma (PA). Patients and Methods: A retrospective cohort study was conducted on PA patients who underwent surgery at Rajavithi Hospital. Baseline characteristics and visual parameters, including visual acuity (VA) and visual field (VF), were analyzed in relation to the visual prognosis outcome. The outcome was defined as VA improvement at 1-year postoperatively. Visual parameters were measured at each follow-up visit and compared. Factors for improved visual prognosis were evaluated using logistic regression analysis. Results: A total cohort of 87 patients (64.37% female), 62.07% showed improvement in visual outcome. Most improvement occurred immediately after surgery, evident at the 1-month visit. The mean follow-up time was 47.45 months (±28.49 SD), mean difference in VA improvement at 1-year was -0.56 logMAR (95% CI -0.73, -0.47). In multivariable logistic regression model, prolonged onset duration was associated with a reduced odds of improved visual outcome, with an odds ratio (OR) of 0.946 (95% CI 0.899-0.996, p = 0.034). Baseline characteristics, tumor volume, Hardy and Knops classification, and surgical approaches were not identified as significant predictors. Conclusion: Both TSS and transcranial approaches are effective for pituitary adenoma. A prompt operation is recommended for patients with prolonged onset duration, with thorough discussion on poor postoperative visual outcomes.
RESUMEN
AIM: The aim of this study was to explore the patterns of pediatric uveitis and the types of ocular complications of uveitis and to determine the possible risk factors associated with visual impairment. METHOD: This was a cross-sectional study conducted at Queen Rania Children's Hospital between June 2020 and June 2023. All children diagnosed with uveitis were enrolled in the study. After collecting data from the patients and reviewing their medical records regarding age, gender, and past ocular and medical history, the patients were subjected to a detailed ophthalmic exam including best-corrected visual acuity (BCVA). Anterior segment exam using the slit lamp, intraocular pressure exam using Goldmann applanation tonometry, and posterior segment exam using 78 and 90 diopter Volk lenses were performed. Patients with other ocular diseases that affected visions not related to uveitis were excluded from the study. RESULTS: A total of 82 children, accounting for 130 eyes, were enrolled in this study, with ages ranging from 2 to 16 years (mean age 10.5±4.3 years). Among them, 27 were males, constituting 32.9% of the participants. Unilateral uveitis was observed in 34 eyes, representing 26.2% of cases. The mean age of uveitis onset was 6.9±1.9 years, and the mean disease duration was 4.8±0.4 years. The majority of cases i.e. 90.8% (n = 74) were non-infectious, with 92.3% (n = 76) classified as non-granulomatous and 79.2% (n = 65) categorized as chronic. Anterior uveitis was the most prevalent site of inflammation in 70.8% of cases (n = 58), followed by panuveitis in 20.0% of cases (n = 16), intermediate uveitis in 6.2% of cases (n = 5), and posterior uveitis in 3.0% of cases (n = 2). The cause of uveitis could not be identified in 40.0% (n = 33) of cases. Juvenile idiopathic uveitis emerged as the most commonly known disorder associated with uveitis in 40.0% (n = 33) of cases. Complications were identified in 52.3% (n = 43) of cases, with posterior synechiae being the most prevalent; 26.9% (n = 22) demonstrated an improvement in BCVA, while 21.5% (n = 18) experienced a decline in BCVA relative to the initial assessment Conclusion: Pediatric uveitis tends to manifest as anterior, chronic, bilateral, and non-granulomatous. Higher frequencies of severe visual impairment are linked to panuveitis, infectious and granulomatous uveitis, early-onset, long-duration cases, and male gender. The use of biologics has a positive effect, significantly improving or preserving visual acuity.
RESUMEN
Purpose: To assess long-term visual and neurodevelopmental outcomes in children with congenital Zika syndrome (CZS) after strabismus surgery. Methods: A consecutive sample of five children with CZS who underwent strabismus surgery was enrolled. All children underwent a standardized pre- and postoperative protocol including binocular best-corrected visual acuity (BCVA) using the Teller Acuity Cards II (TAC II), ocular alignment, functional vision using the functional vision developmental milestones test (FVDMT), and neurodevelopmental milestone evaluation using the Bayley Scales of Infant Development-Third Edition (BSID-III). Scores of the FVDMT outcomes considering the child's developmental age based on the BSID-III score were compared with scores from postoperative assessment. Results: Five children with CZS (3 girls, 2 boys) were enrolled with a mean age at baseline (preoperative) of 35.0 ± 0.7 months (range, 34-36 months) and at final assessment of 64.4 ± 0.5 months (range, 64-65 months). Preoperative BCVA was 1.2 ± 0.5 logMAR and at final assessment 0.7 ± 0.1 logMAR. Successful strabismus surgery outcome was maintained in 4/5 (80.0%) of children at final assessment. The children's BSID-III scores showed significant neurodevelopment delay at the initial assessment (corresponding developmental mean age was 4.7 months) and at their final assessment (corresponding developmental mean age was 5.1 months). There was improvement or stability in 34/46 items evaluated in the FVDMT (73.9%) when comparing baseline with 2-year follow-up. Conclusions: Strabismus surgery resulted in long-term ocular alignment in the majority of children with CZS. All the children showed improvement or stability in more than 70.0% of the functional vision items assessed. Visual and neurodevelopmental dysfunction may be related to complex condition and associated disorders seen in CZS including ocular, neurological, and skeletal abnormalities.

INTRODUCTION: This study was conducted to describe the epidemiology, prognostic factors, and visual outcomes of open globe injuries (OGIs) at a tertiary care centre in Western Rajasthan, India. METHODS: Data of OGI patients treated at the Department of Ophthalmology, All India Institute of Medical Sciences, Jodhpur, Rajasthan, from March 2019 to December 2021 were reviewed retrospectively. Demographic details including age, gender, place of injury, wound characteristics (i.e., cause, mechanism, location, and size), visual acuity (VA), and associated ocular injuries were recorded. The Ocular Trauma Classification System (OTCS) and the Birmingham Eye Trauma Terminology (BETT) were used to categorize OGIs. All the data was entered into a Microsoft Excel sheet (Microsoft Corporation, Redmond, Washington, United States) and analyzed with IBM SPSS Statistics for Windows, Version 23.0 (Released 2015; IBM Corp., Armonk, New York, United States). RESULTS: A total of 40 patients with OGIs were included. OGI was discovered to be four times higher in males and 47.5% of the total cases were observed in patients aged 0-15 years, followed by patients aged 16-30 (27.5%). The rupture injury showed a higher incidence rate (32.5%) than the penetrating injury (62.5%). Of all OGIs, 75% were grade 4 injuries, with zone 1 being the most often affected zone and wood stick injury being the most prevalent aetiology. A significant difference was noted (p<0.001) in comparing presenting VA with final VA with paired sample t-test. A negative Spearman correlation was noted between age and final VA (r = 0.53, p = 0.000), and the grade of injury and final VA (r = 0.51, p = 0.001.) Conclusion: Young males were the most susceptible group to sustain OGIs due to their more physical activities. Health education and safety in the workplace and during sports are crucial to reduce the incidence of OGI.
RESUMEN
PURPOSE: To examine the real-world management and outcomes of uveitic cystoid macular oedema (CME). DESIGN: Retrospective study. METHODS: Patients with uveitic CME were identified from the Inflammatory Eye Disease database. 248 eyes of 218 patients with uveitic CME were identified. Main Outcome Measures: Time to resolution, time to recurrence and vision loss. RESULTS: Median age at time of CME was 51.7 years [IQR 37.3-63.9]. Overall likelihood of resolution was 209/248 eyes (85.3%). Resolution occurred in 34.1% with topical therapy, 69.2% treated with oral prednisone (72.9% if prednisone dose ≥ 60 mg/day), 73.5% treated with orbital floor steroid, and 86.7% treated with intravitreal steroid. On multivariate analysis, ERM was associated with decreased resolution of CME (HR 0.735 p = 0.045). Additionally, infectious aetiology approached significance (HR 0.635 p = 0.059) for CME resolution. Recurrence occurred in 85 eyes (36.5%). Predictors of increased likelihood of recurrence were current smoking status (HR 1.818 p = 0.042) and subretinal fluid at diagnosis (HR 1.577 p = 0.043). Eyes with infectious aetiology had lower chance of CME resolution, but those that did resolve had lower probability of recurrence (HR 0.891 p = 0.019). Moderate vision loss (20/50-20/200) occurred in 24 eyes (9/7%) and severe vision loss (≤20/200) in 17 eyes (6.9%). CONCLUSIONS: Management of CME is challenging given the heterogeneous aetiologies, severity of the macular edema as well as response to the therapy. A high rate of resolution was observed, given sufficient time, but recurrence occurs in one-third. Current smoking status plays an important role in the risk of recurrence of CME and patients should be encouraged to stop smoking.
RESUMEN
AIMS: The aims of this study are to investigate the etiology, microbiological spectrum, and risk factors associated with visual outcomes of fungal endophthalmitis (FE) in a tertiary eye specialty hospital in Shanghai, China. METHODS: This was a retrospective, single-center case series. The clinical characteristics, etiology, microbiological spectrum, and management, as well as the visual outcomes, were analyzed. Logistic regression was used to analyze the factors related to visual outcomes. RESULTS: This study involved 102 eyes of 92 patients with FE, including 63 males (66.3%). The mean age was 44.4 ± 19.8 years. The most common etiology of FE was trauma (56.5%). The predominant fungal species isolated were Aspergillus spp. (31/93, 33.3%). Pars plana vitrectomy (PPV) and intravitreal antifungal agents was performed initially in 86 (84.3%) and 83 (81.4%) eyes, respectively. Only 35 (34.3%) eyes achieved final best corrected visual acuity (BCVA) of 20/400 or better. Ten (9.8%) eyes had a final BCVA of light perception or worse, and five (4.9%) had to be enucleated. The factors determining better visual outcomes included initial visual acuity better than finger-counting (FC) (odds ratio (OR) 5.811, p = 0.036), the absence of corneal infiltrate (OR 10.131, p = 0.002), and Candida species infection (OR 6.325, p = 0.011). CONCLUSIONS: Early diagnosis of FE and a timely vitrectomy, combined with an intravitreal injection of an antifungal drug, can mitigate the devastating results of intraocular fungal infection. Not being infected by Aspergillus spp., an initial BCVA that was no worse than FC, and the absence of corneal involvement were related to better visual prognosis.
RESUMEN
Purpose: To compare and evaluate uncorrected visual acuity (UCVA) from far to near distance for four different optical designs of intraocular lenses (IOLs), developed on the same IOL platform. Patients and Methods: In a cohort of 121 patients, who underwent uncomplicated cataract surgery in Zengyo Suzuki Eye Clinic, Japan, between June 2018 and November 2023, and who received a single-piece TECNIS OptiBlue™ platform series IOL, the following four groups were established based on the IOL implant type: ZCB00V (TE), ZXR00V (SF), DFR00V (SG), and DIB00V (EH). UCVA at 5 m, 1 m, 70 cm, 50 cm, 40 cm, and 30 cm, as well as contrast sensitivity (with and without glare), was compared at one month post-operation. Results: Regarding diffractive IOLs, patients in the SG group demonstrated significantly improved visual acuity at 5 m, 50 cm, 40 cm, and 30 cm, while those in SF group performed significantly better at 1 m. Among non-diffractive IOLs, patients in the EH group demonstrated significantly improved visual acuity scores at 1 m, 70 cm, 40 cm, and 30 cm, compared to individuals in the TE group, with comparable results between the two groups at 5 m and 50 cm. Patients in the SF and EH groups achieved similar results for visual acuity and contrast sensitivity, while those in the SG group exhibited a distinctive decrease in contrast sensitivity (with glare) relative to the other three groups. Conclusion: DFR00V seemingly provides excellent UCVA from near to far distances, aiming for spectacle independence, although at the potential cost of decreased contrast sensitivity compared to the other three IOL types. Furthermore, although ZXR00V and DIB00V differ lens structures, they may nonetheless provide similar visual quality and spectacle independence in daily life.
The study focused on the TECNIS platform, specifically the OptiBlue lens, which is available primarily in Japan. Uncorrected visual acuity (UCVA) from far to near distance was compared and evaluated among four optical designs of intraocular lenses (IOLs), developed on the same IOL platform.
RESUMEN
The prognosis of 11,778 mitochondrial mutations in Leber hereditary optic neuropathy (LHON) is poor. Patients with favorable outcomes (visual acuity better than 20/100) who could be observed for more than 6 months were analyzed. Among 74 patients (57 male, 17 female), 6 (8.1%) showed improvement in visual acuity of 20/100 or higher. The patients with favorable outcomes have better visual acuity at nadir (logMAR 0.98 ± 0.69 in the favorable patients and logMAR 2.32 ± 0.93 in the unfavorable patients, p = .003). Among the favorable group, four patients (36, 32, 19, and 7 years of age at onset) took idebenone within 6 months of onset. However, fifty-one percent of the patients with unfavorable outcomes took idebenone (p = .008). Although the age at onset in the favorable patients is relatively younger than that of the unfavorable patients (20.3 ± 10.8 versus 28.8 ± 12.8 years), a significant difference was not found (p = .138). In conclusion, better visual acuity in nadir and administration of idebenone may affect vision recovery.

The limited accessibility to ophthalmological services in remote regions of developing countries poses a significant challenge in visual healthcare. Cataracts and refractive errors are prominent causes of visual impairment, and surgery, despite being an efficient option, faces barriers in developing countries due to financial and geographical constraints. Humanitarian missions play a vital role in addressing this issue. The improvement in the accuracy of calculating IOL power through techniques such as keratometry and biometry is a fundamental step towards optimizing surgical outcomes and the quality of life for patients in these underserved regions. In this context, the consideration of keratometry and immersion ultrasound biometry as preoperative assessment standards in cataract surgeries in developing countries is presented as a pertinent and advisable strategy.

Objective: Treatment strategies for craniopharyngiomas are still under debate particularly for the young population. We here present tumor control and functional outcome data after surgical treatment focusing on stereotactic and microsurgical procedures for cystic craniopharyngiomas in children and adolescents. Methods: From our prospective institutional database, we identified all consecutive patients less than 18 years of age who were surgically treated for newly-diagnosed cystic craniopharyngioma between, 2000 and, 2022. Treatment decisions in favor of stereotactic treatment (STX) or microsurgery were made interdisciplinary. STX included aspiration and/or implantation of an internal shunt catheter for permanent cyst drainage. Microsurgery aimed for safe maximal tumor resections. Study endpoints were time to tumor recurrence (TTR) and functional outcome including ophthalmological/perimetric, endocrinological, and body-mass index (BMI) data. Results: 29 patients (median age 9.9 yrs, range 4-18 years) were analyzed. According to our interdisciplinary tumor board recommendation, 9 patients underwent stereotactic treatment, 10 patients microsurgical resection, and 10 patients the combination of both. Significant volume reduction was particularly achieved in the stereotactic (p=0.0019) and combined subgroups (p<0.001). Improvement of preoperative visual deficits was always achieved independent of the applied treatment modality. Microsurgery and the combinational treatment were associated with higher rates of postoperative endocrinological dysfunction (p<0.0001) including hypothalamic obesity (median BMI increase from 17.9kg/m2 to 24.1kg/m2, p=0.019). Median follow-up for all patients was 93.9 months (range 3.2-321.5 months). Recurrent tumors were seen in 48.3% and particularly concerned patients after initial combination of surgery and STX (p=0.004). In here, TTR was 35.1 ± 46.9 months. Additional radiation therapy was found indicated in 4 patients to achieve long-lasting tumor control. Conclusion: In children and adolescents suffering from predominantly cystic craniopharyngiomas, stereotactic and microsurgical procedures can improve clinical symptoms at low procedural risk. Microsurgery, however, bears a higher risk of postoperative endocrine dysfunction. A risk-adapted surgical treatment concept may have to be applied repeatedly in order to achieve long-term tumor control even without additional irradiation.
RESUMEN
PURPOSE: To report the first series of Seasonal Hyperacute Pan Uveitis (SHAPU) from Bhutan. METHODS: We retrospectively analyzed the patients with clinically diagnosed SHAPU treated in the referral center in the last 5 years. Data included demographics (age, sex, laterality), region, time of presentation (year, season) and treatment received. RESULTS: The series included 3 males and 2 females. The mean age was 16 years. Three patients had presented in autumn of 2021, and two in autumn of 2019. Four patients presented within 2 weeks of the onset of symptoms. All patients had either exposure or contact with white moths. All patients presented with unilateral sudden painless reduction in vision and low Intraocular pressure. Four patients required vitrectomy. The final visual acuity of 3 patients was >6/36, and one patient was 6/60. CONCLUSIONS AND IMPORTANCE: The time of presentation and early treatment intervention are crucial in achieving good visual prognosis in SHAPU.

INTRODUCTION: The gold standard treatment for indirect traumatic optic neuropathy (ITON) has not yet been conclusively established, and it is essential to gain an understanding of visual prognosis and to counsel patients regarding the predictive risk factors of poor visual outcomes. Currently, there is limited information regarding ITON in Thai populations; therefore, this study aimed to determine the risk factors of poor visual outcome in patients with this condition. METHODS: A retrospective review was conducted of all ITON cases diagnosed at Rajavithi Hospital and Sawanpracharak Hospital between January 2016 and December 2022 in order to determine clinical characteristics and evaluate associated risk factors of poor visual prognosis using binary logistic regression analysis. RESULTS: The mean age of this cohort of 101 patients was 36.17 years, with a male predominance of 73.3 %. Motor vehicle accidents were the most common cause of ITON, with a statistically significant 79.2 % of cases. The patients were categorized into an "improved group" of 29 patients and an "unimproved group" of 72. The unimproved group had a significantly older mean age and poorer initial visual acuity of 20/200 (p-values 0.001 and p < 0.001 respectively). There was no significant difference between Computed Tomography (CT) findings in the two groups. The improved group had significantly better visual acuity (VA) at 1-month and final follow-up visit than the unimproved group (both p < 0.001). Differences between gender, Glasgow coma score, associated underlying diseases, and duration from trauma to intravenous glucocorticoids therapy in the two groups were not statistically significant. Multivariable logistic regression analysis identified patient age of 40 years or more (Odds ratio (OR) 3.447, 95 % CI, 1.085-10.955, p = 0.036) and poor baseline VA (OR 6.628, 95 % Confidence Interval (CI), 2.308-19.036, p < 0.001) as significant risk factors for poor visual outcome in ITON patients. CONCLUSIONS: No clear benefit was found of intravenous glucocorticoids in treatment of ITON. Patients aged 40 years or more and/or with poor baseline visual status should be advised that they are at increased risk of poor final visual outcomes.
