Assessing Agreement and Variability Among Alternative Devices for Intraocular Pressure Measurement: A Comparative Study.

Purpose: Intraocular pressure (IOP) measurement is critical in diagnosing and managing eye conditions. This study aims to assess the comparability of three alternative devices for measuring IOP: Noncontact tonometer, Icare rebound tonometer, and Tono-Pen. Patients and Methods: A cross-sectional study included 172 adult participants (87 males and 85 females) who underwent IOP and central corneal thickness (CCT) assessments. IOP was measured using Noncontact (Canon TX-20), Icare (Icare TA01i), and Tono-Pen (Tonopen XL). CCT was measured with the built-in pachymetry of the Noncontact tonometer. Correlation coefficients and Bland-Altman analyses were conducted to assess the relationships and agreements between these tonometers. Participants were grouped based on IOP and CCT levels. The mean of the standard deviation of the three tonometer results was calculated to evaluate measurement result variability. One-way analysis of variance was conducted for comparing between the groups. Results: IOP measurements among the three devices were not significantly different, indicating their comparability. Correlation analysis revealed strong correlations between the tonometers. Bland-Altman analysis showed good agreement, with the Icare rebound tonometer and Tono-Pen exhibiting narrower limits of agreement. Furthermore, IOP levels influenced measurement result variability, with higher IOP levels associated with greater variance. Conclusion: This study demonstrates that the alternative devices examined can provide reliable IOP measurements. It highlights the potential of these alternative devices for IOP measurement. These findings have implications for clinical practice, offering practitioners additional tools for accurate IOP assessment.

Functional and Anatomical Outcomes of Anti-Vascular Endothelial Growth Factor Treatment for Exudative Age-Related Macular Degeneration with or without Obstructive Sleep Apnea.

(1) To investigate the functional and anatomical outcomes of anti-vascular endothelial growth factor (anti-VEGF) treatment in patients with exudative age-related macular degeneration (AMD) with or without obstructive sleep apnea (OSA); (2) In total, 65 patients with AMD with or without OSA who received three consecutive doses of intravitreal anti-VEGF injections were enrolled. The primary outcomes-best-corrected visual acuity (BCVA) and central macular thickness (CMT)-were assessed at 1 and 3 months. Moreover, morphological changes observed through optical coherence tomography were analyzed; (3) In total, 15 of the 65 patients had OSA and were included in the OSA group; the remaining 50 patients were included in the non-OSA (control) group. At 1 and 3 months after treatment, BCVA and CMT had improved but did not differ significantly between the groups. More patients in the OSA group demonstrated subretinal fluid (SRF) resorption at 3 months after treatment than in the non-OSA group (p = 0.009). Changes in other imaging biomarkers, such as intraretinal cysts, retinal pigment epithelium detachment, hyperreflective dots, and ellipsoid zone disruptions, did not differ significantly between the groups; (4) Our results suggest that the BCVA and CMT outcomes 3 months after anti-VEGF treatment are similar between patients with and without OSA. Moreover, patients with OSA may exhibit superior SRF resorption. A large-scale prospective study is mandatory to evaluate the association between SRF resorption and visual outcomes in AMD patients with OSA.

Using A modified quickert procedure combined with prolapsed fat and preseptal orbicularis muscle removal to correct involutional lower eyelid entropion in Asians.

PURPOSE: To propose a modified Quickert procedure combined with prolapsed fat and preseptal orbicularis muscle removal which corrects involutional lower eyelid entropion, and to validate the procedure as an adequate surgical management according to anatomical deformities and pathogenesis of Asian patients. METHODS: Ninety-five patients (45 men, 50 women; 108 eyelids [55 right eyes, 53 left eyes]) who underwent this modified surgical procedure with a minimum follow-up period of 2 months were examined. All pre- and post-operative evaluations and surgical procedure were performed exclusively from the same oculoplastic surgeon. Postoperative results, recurrence rate, and complications were assessed. RESULTS: The mean follow-up period was 13.33 months (range, 2-67 months). Of the 108 eyelids, 4 developed recurrent entropion with trichiasis, corresponding to an overall recurrence rate of 3.70%. No major complications, such as overcorrection (ectropion), symblepharon, infection, or wound dehiscence, occurred during the follow-up period after surgery. Of these 4 eyelids exhibiting recurrence, 3 occurred within 10 months and 1 occurred 49 months after surgery. Three recurrent patients received secondary surgery for re-correction with successful results. CONCLUSION: The modified Quickert procedure combined with prolapsed fat and preseptal orbicularis muscle removal not only demonstrated safety and effectiveness, but also led to low rate of recurrence and complications. It could be a strategy for correction of involutional entropion in Asian patients.

The clinical presentation and treatment of an invasive conjunctival squamous spindle cell carcinoma.

Ocular surface squamous neoplasia represents neoplastic epithelial abnormalities of conjunctiva and cornea, ranging from squamous dysplasia to invasive squamous cell carcinoma and is both sight- and life-threatening. Squamous spindle cell carcinoma (SSCC) of conjunctiva is a rare variant with distinct behavior which is thought to be more locally aggressive. We describe an 83-year-old woman with a progressively enlarging huge SSCC in her right eye over the past 2 years. The tumor bulged out with local invasion into intraocular and orbital cavities. Wide excision of the tumor with frozen section control was performed. After surgery, topical 0.03% mitomycin C was given as adjuvant therapy. At 40-month follow-up, the lesion site showed no evidence of local recurrence. This case provides a valuable and complete experience of the clinical presentation for the progression and treatment of this rare disease.

Sex-Specific Effect of Obesity on Epiblepharon in Different Age Groups: A Case-Control Study.

Obesity has been regarded as a risk factor for several ocular diseases. This study aims to investigate the age- and sex-specific relationship between epiblepharon and obesity in children. A retrospective case-control study was conducted using the Chang Gung Research Database. Children ≤ 18 years of age with epiblepharon were identified from 1 January 2009 to 31 December 2019. Children were classified into three groups: normal, overweight and obese groups. A total of 513 patients and 1026 controls (57.7% males) aged 1 to 18 matched by sex and age were included in the analysis. The median body mass index (BMI) of children with epiblepharon was significantly higher than that of children without epiblepharon (p < 0.001). In the subgroup analysis, among boys aged 4 to 9 years, the BMI in boys with epiblepharon was significantly higher than that in boys without epiblepharon (p < 0.05) and the risk of epiblepahron in overweight/obese boys was significantly higher than in non-overweight boys (OR = 1.74, 95% CI = 1.07-2.82 for age 4 to 6; OR = 3.06, 95% CI = 1.56-6.03 for age 7 to 9). On the other hand, among girls aged 13 to 18 years, the BMI in adolescent girls with epiblepharon was significantly higher than that in the control group (p < 0.05) and overweight/obese girls had a statistically higher risk of persistent epiblepharon than non-overweight girls (OR = 3.70, 95% CI = 1.38-9.97). The association between obesity and epiblepharon varies in strength according to age in a sex-specific manner.

Trends in Infectious Keratitis in Taiwan: An Update on Predisposing Factors, Microbiological and Antibiotic Susceptibility Patterns.

Infectious keratitis (IK) represents a major cause of corneal blindness. This study aims to investigate the demographics, risk factors, microbiological characteristics and antibiotic susceptibility patterns of IK in Taiwan over the past 15 years. A retrospective population-based study was conducted using the Chang Gung Research Database. Patients with IK were identified by diagnostic codes for corneal ulcer from 2004 to 2019. Of 7807 included subjects, 45.2% of patients had positive corneal cultures. The proportion of contact lens-related IK declined, while that of IK related to systemic diseases grew. The percentage of isolated gram-positive bacteria surpassed that of gram-negative bacteria in the 15-year period. The prevalence of Pseudomonas aeruginosa showed a decreasing trend (p = 0.004), whereas coagulase-negative Staphylococcus (CNS) and Propionibacterium species were increasingly detected (p < 0.001). Overall, the trend of antibiotic susceptibility of both gram-positive and gram-negative bacteria did not change throughout the study period. The susceptibility to the test antibiotics maintained over 90% in gram-negative isolates over 15 years. Vancomycin preserved 100% susceptibility to all gram-positive isolates. Since most tested antibiotics exhibited stable susceptibility over decades, this study reinforced that fluoroquinolones and fortified vancomycin continue to be good empiric therapies for treating bacterial keratitis in Taiwan.

Non-Arteritic Anterior Ischemic Optic Neuropathy Following COVID-19 Vaccination.

People are advised to receive a vaccine booster as the Delta and Omicron variants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) emerge, but various adverse ocular reactions after vaccination have been reported. NAION following COVID-19 vaccination appears extremely rarely. Here, we report a case of a 61-year-old female with sudden painless blurred vision developing NAION after receiving ChAdOx1 nCoV-19 (AstraZeneca) vaccination and provide an in-depth explanation of the possible mechanisms regarding the hypercoagulable state after vaccination. Our report adds to the literature on potential adverse ocular effects after COVID-19 vaccination, and we as ophthalmologists recommend that clinicians should increase awareness of this possible ocular complication when evaluating patients with sudden visual disturbance with a recent history of vaccination.

Collision tumor of sebaceous carcinoma and squamous cell carcinoma of the eyelid: Case report.

BACKGROUND: Collision tumors are rare clinical entities that two heterogeneous neoplasms are concurrently adjacent to each other at the same location. The association of a squamous cell carcinoma and a malignant adnexal tumor is even infrequent. CASE PRESENTATION: The case of a 79-year-old woman having a slow-growing and painless tumor on the left lower eyelid was presented. The lesion, about 15 mm in diameter, was nodular, irregular, and yellow-discolored. Histopathologic and immunohistochemical findings disclosed concurrence of sebaceous carcinoma as well as squamous cell carcinoma in one specimen. Wide excision of the tumor with frozen section control and eyelid reconstruction were performed. Oncologic survey revealed no other lesion. At 6-month follow-up, no evidence of recurrence or metastasis was presented. CONCLUSION: Collision tumor composed of sebaceous carcinoma and squamous cell carcinoma in eyelid may be the first case described in the literature. For increasing accuracy of diagnosis and management, a thorough clinical examination and detailed histopathologic analysis, along with multidisciplinary discussion, are prerequisites.
