Purpose: To characterize ocular surface temperature (OST) in healthy eyes and its association with systemic risk factors of cardiovascular and ischemic heart disease. Methods: This prospective cross-sectional study included consenting subjects who were examined at the Institute for Medical Screening in Sheba Medical Center. A Therm-App™ thermal imaging camera (Opgal LTD, Israel) was used for OST acquisition, and the mean OST of the medial canthal, lateral canthal, and central cornea regions were measured. Room and body temperatures were also recorded. Past medical and ocular history as well as data from various clinical examinations performed at the same visit were obtained. Results: Thermographic images were obtained from 186 subjects, 150 of which were included in the final analysis. OST was significantly higher in the medial canthal, central cornea, and lateral canthal regions in people with a history of ischemic heart disease (p = 0.02, p = 0.02, and p = 0.03, respectively). There were no significant OST differences (ANOVA test) associated with the presence of hypertension, diabetes mellitus, or active smoking status. Conclusions: OST correlated positively with the presence of ischemic heart disease. This correlation, its pathophysiological base, and its clinical application warrants further investigation.

Purpose: To evaluate high-risk histopathological features following primary enucleation of eyes with retinoblastoma and assess the patient outcomes across continents. Methods: A retrospective study of 1,426 primarily enucleated retinoblastoma eyes from five continents. Results: Of all, 923 (65%) were from Asia (AS), 27 (2%) from Australia (AUS), 120 (8%) from Europe (EUR), 162 (11%) from North America (NA), and 194 (14%) from South America (SA). Based on the continent (AS vs. AUS vs. EUR vs. NA vs. SA), the histopathological features included massive choroidal invasion (31% vs. 7% vs. 13% vs. 19% vs. 27%, P = 0.001), postlaminar optic nerve invasion (27% vs. 0% vs. 16% vs. 21% vs. 19%, P = 0.0006), scleral infiltration (5% vs. 0% vs. 4% vs. 2% vs. 7%, P = 0.13), and microscopic extrascleral infiltration (4% vs. 0% vs. <1% vs. <1% vs. 4%, P = 0.68). Adjuvant chemotherapy with/without orbital radiotherapy was given to 761 (53%) patients. Based on Kaplan–Meier estimates in different continents (AS vs. AUS vs. EUR vs. NA vs. SA), the 6-year risk of orbital tumor recurrence was 5% versus 2% versus 0% versus 0% versus 12% (P < 0.001), systemic metastasis was reported in 8% versus 5% versus 2% versus 0% versus 13% (P = 0.001), and death in 10% versus 3% versus 2% versus 0% versus 11% (P < 0.001) patients. Conclusion: There is a wide variation in the infiltrative histopathological features of retinoblastoma across continents, resulting in variable outcomes. SA and AS had a higher risk of orbital tumor recurrence, systemic metastasis, and death compared to AUS, EUR, and NA.

Objective To determine the effect of perinatal and neonatal risk factors on retinopathy of prematurity (ROP) and to examine the association of fertility treatments on the risk for ROP in very low birth weight (VLBW) preterm twins. Methods The population-based observational study consisted of VLBW twins born at 24–29 weeks gestational age (GA). Data from the Israel national database (1995–2020) were applied. Univariate and multivariable logistic regression using the General Estimating Equation were used for assessment of risk factors. Results The study population comprised 4092 infants of whom 2374 (58%) were conceived following fertility treatments. ROP was diagnosed in 851 (20.8%) infants. The odds for ROP approximately doubled with each week decrease in GA: at 24 weeks, Odds Ratio (OR) 58.00 (95% confidence interval (CI) 31.83–105.68); 25 weeks, OR 25.88 (95% CI 16.76–39.96); 26 weeks, OR 12.69 (95% CI 8.84–18.22) compared to 29 weeks GA. Each decrease in one birthweight z-score was associated with 1.82-fold increased risk for ROP (OR, 1.82, 95% CI 1.59–2.08). Infertility treatments were not associated with ROP. Neonatal morbidities significantly associated with ROP were surgical necrotizing enterocolitis (NEC) (OR, 2.04, 95% CI 1.31–3.19); surgically treated patent ductus arteriosus (PDA) (OR, 1.63, 95% CI 1.12–2.37); sepsis (OR, 1.43, 95% CI 1.20–1.71) and bronchopulmonary dysplasia (OR, 1.52, 95% CI 1.22–1.90). Conclusion Among preterm VLBW twins, poor intrauterine growth and surgical interventions for NEC and PDA were associated with high odds for ROP. This study does not support an association of fertility treatments with increased risk for ROP.

Objective: The transnasal endoscopic approach may provide better visualisation and a safer approach to the orbital apex. This study presents a case series of orbital apex lesions managed by this approach.Method: This study was an eight-year retrospective analysis of seven patients who were operated on for orbital apex lesions in two tertiary medical centres.Results: Complete tumour removal was performed in three patients and partial removal was performed in four patients. Visual acuity improved in three patients, remained stable in one patient and decreased in the other two patients. The visual field improved in four patients and did not change in two patients. Complications included worse vision and visual fields in 28.6 per cent of patients and late enophthalmos (of −1.25 ± 4.6 mm) in 2 patients.Conclusion: The transnasal approach to orbital apex lesions in selected cases may provide a rational alternative to transorbital surgery. Complete tumour removal should be weighed against the risk of damage to the optic nerve.

Purpose: The purpose of this study was to investigate the visual results and patient satisfaction after implantation of an extended depth-of-focus (EDOF) intraocular lens (IOL) in the second eye of patients implanted previously with a monofocal IOL in the first eye. Methods: The medical records and self-reported questionnaires from patients who were implanted with monofocal IOLs in the first eye and EDOF IOLs in the second eye (group A) and from patients implanted bilaterally with EDOF IOLs (group B) were compared for visual acuity (VA), spectacle independence, patient satisfaction, and photic phenomena. Results: Group A (23 eyes of 23 patients) had similar distance uncorrected VA and intermediate uncorrected VA compared with group B (72 eyes of 36 patients) (0.03±0.05 vs. 0.04±0.16; P=0.136 and 0.660, respectively). There was a tendency toward a better near uncorrected VA in group A compared with group B (0.15±0.14 vs. 0.23±0.17; P=0.074). Patients’ perception of their VA was similar between groups. Spectacle independence for distance vision was reported by 16/17 (94.1%) and 35/36 (97.2%) patients (P=0.543), 13/17 (76.5%) and 32/36 (88.9%) patients (P=0.252) for intermediate vision, and 4/17 (23.6%) and 22/36 (61.1%) patients for near vision (P=0.011), in groups A and B, respectively. There was no difference in complaints of photic phenomena between groups. Conclusions: Patients previously implanted with a monofocal IOL in 1 eye who are interested in improving their spectacle independence can be considered for an EDOF IOL implantation in the second eye and may have similar results to those implanted bilaterally with EDOF IOLs.
