A variety of daily activities can intentionally or unintentionally cause the Valsalva manoeuvre, which induces a physiological response of elevated peripheral venous pressure. Studies have speculated that it may ultimately affect the choroidal anatomy. This is particularly important from a clinical point-of-view since patients occasionally hold their breath while undergoing macular optical coherence tomography (OCT). In this study, we systematically reviewed the literature to understand the impact of the Valsalva manoeuvre on the choroid and conducted meta-analyses on the changes induced in the subfoveal choroidal thickness (SFCT) and the choroidal vascularity index (CVI). We searched 12 literature databases for studies in healthy participants undergoing Valsalva manoeuvre with choroidal OCT scans before and during the manoeuvre. Seven studies with a total of 444 eyes of 279 individuals were eligible for the review. The Valsalva manoeuvre led to a statistically significant but numerically small increase in the SFCT of 6.5 μm (95% CI: 1.6-11.4 μm; p = 0.01) and a statistically significant increase in the CVI of 1.48 (95% CI: 1.23-1.73; p = 0.0002). Thus, the Valsalva manoeuvre has a measurable impact on the choroid, and we recommend careful observation of how the patient sits and behaves behind the OCT scanner while scanning in order to allow accurate measurements of the choroid for diagnosis and monitoring.

Purpose: To assess the predictive performance of DIGIROP-v1.0 models in identifying treatment-requiring ROP among infants undergoing ROP screening at a tertiary neonatal intensive care unit in Greece.

Methods: Retrospective cohort analysis of 640 consecutive screened preterm infants with gestational age (GA) 24^0/7 to 30^6/7 weeks and known ROP outcome in the 2nd Neonatology Department of Aristotle University of Thessaloniki (2009-2021). The primary outcome was the development of type 1 ROP according to the Early Treatment of ROP criteria or treatment based on the ophthalmologist's judgement. Sensitivity, specificity, area under the curve (AUC) with corresponding 95% confidence intervals (CI) and calibration plots for the DIGIROP-v1.0 models were displayed.

Results: The DIGIROP-Birth-v1.0 model correctly identified 35/43 treated infants (sensitivity 81.4% [95% CI, 66.6%-91.6%], specificity 61.5% [95% CI, 57.4%-65.4%], AUC 0.82 [95% CI, 0.75-0.90]). During the postnatal weeks 6-14 the sensitivity of the DIGIROP-Screen-v1.0 model ranged from 82.6% to 100%. Eleven infants, all with severe comorbidities, that is, congenital malformation(s), syndrome(s), hydrocephalus or history of intestinal surgery, that were treated, were missed by the model, but met criteria for screening according to DIGIROP-v1.0 models' recommendations, and to our unit's routine standards.

Conclusion: The DIGIROP-v1.0 models resulted in lower sensitivity and higher specificity in this Greek cohort compared with the Swedish development group. Despite higher GA and BW, infants in our cohort had higher incidence of treated ROP than in Sweden, resulting in an under-estimation of their risk for treatment-requiring ROP. Further validation of the DIGIROP-v2.0 models and potential adjusting are recommended to maximize generalizability in populations with different characteristics.

Purpose: Glaucoma incidence in patients with endogenous Cushing's syndrome (CS) has never been established. We aim to assess the risk for glaucoma among CS patients compared to controls and determine the age of disease onset.

Methods: A nationwide retrospective matched-cohort study of patients with endogenous CS diagnosed between 2000 and 2023. Patients with CS were matched in a 1:5 ratio, with a control group individually matched for age, sex, socioeconomic status and body mass index. Main outcomes were the incidence of glaucoma and disease onset.

Results: A total of 609 patients [396 women (65%); mean age 48.1 ± 17 years] were included in the CS group and 3018 controls. Follow-up duration was 14.6 years (IQR 9.8-20.2) for the study group. The aetiology of hypercortisolism was divided into pituitary (259, 42.6%), adrenal (206, 33.8%) and unconfirmed aetiology (144, 23.6%) patients. At baseline, 44 (7.2%) CS patients had a diagnosis of glaucoma, compared with 151 (5%) controls. The overall risk for glaucoma was 74% higher in patients with CS compared with matched controls (hazard ratio = 1.74, p = 0.002). Patients with CS who developed glaucoma were younger (mean age of 62 ± 14.7 years) than controls (mean ± SD age, 62 ± 14.7 years), (p = 0.02). The overall risk for glaucoma in CS was high for both patients in remission and patients with persistent hypercortisolism (p = 0.048). Patients with active hypercortisolism experienced an earlier glaucoma onset (82.1 ± 88.0 months).

Conclusions: Endogenous CS is associated with increased risk for glaucoma regardless of remission status and develops at a younger age compared with the general population.

Purpose: The purpose of this study is to investigate 3-year efficacy of orthokeratology lenses (OKL) in controlling axial length progression in myopic Scandinavian children. Through a cross-over design of the control group to compare the treatment efficacy in younger versus older children, with the latter having higher cycloplegic spherical refractive error (cSEQ) at treatment initiation. Further, the study aimed to evaluate the safety of the treatment.

Methods: This was a continuation of the randomized controlled study Clinical study Of Near-sightedness; TReatment with Orthokeratology Lenses (CONTROL study) in which the follow-up period of the original intervention group, that received OKL, was extended from 18 months to 36 months. Meanwhile, the original control group was crossed-over to OKL after the 18-month follow-up visit and treated for 18 months. Biometry was measured using Lenstar LS900, and contact lens complications were graded according to Efron Grading Scale for Contact Lens Complications (Efron score). Mixed models were used for statistical analysis.

Results: Nineteen subjects in the OKL group and 28 in the control group completed the CONTROL study. Hereof, 17 and 24 subjects from the OKL group and control group, respectively, agreed to participate in the CONTROL2 study. In the OKL continue group, the treatment efficacy did not decline during the 3-year study period (p-values for follow-up visits were all ≥0.82). There was no statistically significant difference between treatment efficacy when OKL treatment was initiated in younger versus older children (p-value ≥0.14 for all follow-up visits). Low-grade corneal staining was seen in several subjects at some point during the study, but here were no treatment-requiring or sight-threatening adverse events during the study period.

Conclusion: The efficacy of myopia control by OKL was stable during 3 years of treatment. Similar treatment efficacies were found regardless of the age at treatment initiation. No severe adverse events occurred during the study period.

Purpose: Patients with exudative and nonexudative age-related macular degeneration (AMD) can experience physical, mental, social, administrative or financial burden that are associated with the treatment of this progressive chronic disease. The role of healthcare providers in supporting patients who experience high treatment burden can be important, especially when it comes to effective communication. Despite previous research underlining the need to improve patient-provider communication in AMD care, patient experiences with communication, and how these are related to perceived treatment burden, remain underexplored.

Methods: A survey was distributed among Dutch patients with AMD, which contained questions on several aspects of communication with the patient's ophthalmologist, such as the Quality Of communication Through the patients' Eyes (QUOTE-COMM, including task-, affect- and therapy-oriented communication) questionnaire. Patients were primarily enlisted through a patient association.

Results: A total of 162 patients completed the questionnaire, of which 133 provided fully completed responses. While patients reported positive experiences with affect-oriented communication of their ophthalmologist, they rated task- and therapy-oriented communication as below their expectations. Most patients wished to receive (additional) information on AMD-related costs (71%), future perspectives (71%) and coping with negative emotions pertaining to the disease (68%). Both lower experience scores on task- and affect-oriented communication and lower self-efficacy were associated with higher administrative burden and mental burden among patients.

Conclusion: Our study shows that current communication, information provision and decision-making do not fully meet patients' needs and preferences. Enhancing patient-provider communication seems important, as effective dialogue is likely to diminish patients' perceived treatment burden.

Purpose: To report the results of strabismus surgery in a series of patients with Graves' orbitopathy (GO), using topical anaesthesia with intraoperative suture adjustment.

Methods: All first-time strabismus surgeries in patients with GO in our department during the years 2014-2021 (n = 45) were assessed retrospectively. Among these, 31% came from outside our health region due to increased complexity of the strabismus condition. Orbital decompression surgery had been carried out in 58% of the patients prior to strabismus surgery. Patients with less than 2 months of follow-up were excluded from the study. Median follow-up time was 22 months.

Results: Among the total patient material, 37 (82%) could be operated with topical anaesthesia with intraoperative suture adjustment. There were no cases with triggering of the oculo-cardiac reflex during the procedure. Among the 36 patients operated with topical anaesthesia and follow-up time ≥2 months, 11 (31%) needed further surgery. Late overcorrection after recession of the inferior rectus was seen in 19%. At the last control examination, 32 (89%) were diplopia-free in primary and down-gaze position, either with or without weak prisms.

Conclusion: Strabismus surgery in topical anaesthesia with intraoperative suture adjustment appears to be a suitable and safe procedure in most patients with GO, including difficult and complex cases. The patients should be informed about the possibility of additional surgery and/or post-operative need for prism glasses.

Purpose: To describe clinical characteristics in Finnish patients with X-linked retinoschisis (XLRS) longitudinally with emphasis on retinal morphology and genotype-phenotype correlations.

Methods: A retrospective cohort study reviewed medical records from patients with genetically confirmed XLRS from the Department of Ophthalmology, Helsinki University Hospital. Best-corrected visual acuity (BCVA), refraction, colour fundus photography, spectral-domain optical coherence tomography and genetic information were collected.

Results: Fifty-two males were diagnosed at the median age of 7 years (range 1-57) and followed for a median of 8 years (range, 1-49). Baseline findings included macular retinoschisis in 92 (89%), macular atrophy in 25 (24%) and peripheral retinoschisis in 22 (21%) eyes. Vitreous haemorrhage occurred in 10 (10%) eyes, more frequently with peripheral schisis (p < 0.001). Nearly half of the patients, 22 (42%) were classified as visually impaired according to WHO. Median central retinal thickness was similar between initial (355 μm) and latest visits (360 μm) (p = 0.781). Low BCVA was associated with macular atrophy (p < 0.001), ellipsoid zone disruption (p = 0.007) and peripheral retinoschisis (p = 0.006). The three Finnish founder mutations c.214G >A, c.221G >T, and c.325G >C in exon 4 of retinoschisin 1 (RS1) were identified in 40 patients (77%). No associations were found between the genotypes and phenotypes.

Conclusion: Three-fourths of the patients carried the Finnish founder mutations in RS1, but we did not detect any genotype-phenotype association. Macular atrophy was associated with the poorest visual acuity. Ocular compilations were associated with peripheral retinoschisis, suggesting that these patients should be followed more frequently.

Purpose: To determine whether we could establish evidence-based pass/fail criteria for perimetry in the context of the European visual field standards for driving.

Methods: This two-centre, cross-sectional study included participants with binocular visual field loss that had led to revocation of a group-1 driving licence. The participants underwent cognitive and binocular visual testing, including the European Driving Test (EDT), a perimetry algorithm that adheres to the European visual field standards. We used a high-fidelity driving simulator to compare the driving ability of these participants with healthy controls. Two driving instructors classified each driving test as passed or failed. Receiver operating characteristic (ROC) analysis and area under the curve (AUC) determined the ability of perimetry to discriminate between passed and failed driving tests.

Results: The study included 70 participants with visual field loss and 37 controls. A non-significantly higher proportion of controls passed the driving test (75% vs. 63%; p = 0.22). In ROC analysis, contrast sensitivity performed best (AUC of 0.73), followed by NEI VFQ-25 (AUC of 0.64). Peripheral visual field (AUC of 0.56) and central visual field (AUC of 0.47) performed weaker. Combining the central and peripheral visual field, and their interaction, increased AUC to 0.63.

Conclusion: Perimetry was a poor predictor of simulator-based driving test result, and we could not establish appropriate pass/fail criteria for the European visual field standards. Because perimetry is not an accurate diagnostic tool for fitness to drive, a practical driving assessment should be performed in case of doubt.

Purpose: To test the prognostic role of anterior scleral substantia propria (ASSP) thickness in predicting the 3-month response after half-dose photodynamic therapy (PDT) in central serous chorioretinopathy (CSCR) and to assess its clinical relevance of ASSP in different CSCR phenotypes.

Methods: A prospective, exploratory, multi-centre cohort study conducted at IRCCS San Martino Hospital (Genoa, Italy) and Jules-Gonin Eye Hospital (Lausanne, Switzerland). Demographic and clinical data, and optical coherence tomography (OCT) were collected at baseline and 3 months after PDT. Based on OCT images, we categorized CSCR phenotypes and collected clinically relevant imaging metrics. ASSP thickness was obtained from four different measurements using anterior segment (AS) OCT. Multivariable regression models were performed to evaluate the distribution of ASSP thicknesses among different CSCR phenotypes and to test the prognostic role of ASSP thickness in discriminating between PDT responders (complete subretinal fluid reabsorption) and partial responders.

Results: The study cohort comprised 109 Caucasian patients (82 males, 75.2%) with a total of 142 eyes: 84 eyes simple (59.1%) versus 58 eyes complex (40.9%) CSCR. A linear normal model confirmed a positive association between complex CSCR and higher ASSP thickness (β = 26.1, 95% CL = 12.1/40.1, p < 0.001), with a low prevalence of ciliochoroidal effusion loculations in AS-OCT (1/142 eyes, 0.7%). ASSP thickening was positively linked to the presence of posterior cystoid retinal degeneration (PCRD; p = 0.002), indicating a potential role in the pathogenesis of severe CSCR phenotypes. In the subgroup of treated patients (61 eyes), 63.9% had a complete response after PDT. In these patients a logistic binary model highlighted a significantly higher risk of PDT non-responsiveness (OR = 9.62, 95% CL = 2.44/37.9, p = 0.001) associated with a 60-unit increase in ASSP thickness levels. By contrast, other anatomical parameters (i.e., body surface area, age, gender, axial length) showed no remarkable prognostic roles.

Conclusion: This research highlighted the association of ASSP thickening with complex CSCR phenotype in Caucasian patients and its role in predicting PDT efficacy. These findings enhance our comprehension of the anatomical risk factors in patients affected with CSCR and potentially guide a better understanding of non-responsive cases to PDT treatment.
