    Hintergrund Die Farbsehschwäche ist eine häufige Sehstörung. Hauptursache stellen erbliche Abnormalitäten der retinalen Photopigmente dar. Mit dem weiteren Wachstum der Weltbevölkerung wird auch eine Zunahme Betroffener mit Farbsehschwäche erwartet. Methoden Die Daten männlicher Wehrpflichtiger der Rekrutierungsjahrgänge 2008 bis 2017 wurden retrospektiv analysiert. Das Jahr der Rekrutierung, Geburtsjahr der Militäranwärter, Visus, Refraktion (sphärisches Äquivalent) und Farbsehtüchtigkeit (Pseudoisochromatische Ishihara-Tafeln ja/nein) wurden erhoben. Ergebnisse Das Datenset beinhaltete Angaben von 355 567 männlichen Wehrpflichtigen der Rekrutierungsjahre 2008 bis 2017. Die mittlere Anzahl der Militäranwärter pro Jahr betrug 35 566 (MD = 35 440, SD = 1249) mit einem Minimum von 33 998 Militäranwärtern im Jahr 2017 und einem Maximum von 37 594 Rekruten 2011. Das mittlere Alter der Wehrpflichtigen zum Rekrutierungstermin betrug 19.7 Jahre (MD = 19,0 y, SD = 1,1 y). 337 422 (94,9%) der Wehrpflichtigen bestanden den Ishihara Farbsehtest, während bei 18 235 (5,1%) Wehrpflichtigen eine Farbsehschwäche gefunden wurde. Schlussfolgerung Die Prävalenz der Farbsehschwäche in unserer männlichen Kohorte betrug 5,1%. Diese Schätzung liegt leicht unter der bislang für die europäische kaukasische Bevölkerung beschriebenen Häufigkeit.

  • Vergence-Accommodation Conflict: Increased Presbyopia in Virtual Reality
    Item type: Journal Article
    Huang, Ying-Yin; Menozzi, Marino; Lee, Chia-Yen (2024)
    Klinische Monatsblätter für Augenheilkunde
    Background: Performance and symptoms in completing a visual search task on a PC monitor and using a head-mounted display (HMD) were compared for different viewing conditions and between users of different ages. Patients and Methods: Twenty-three young (M = 30 y, SD = 7 y) and 23 older (M = 52 y, SD = 5 y) participants performed a visual search task presented on a PC monitor. The task was repeated using an HMD for a near and a far virtual viewing distance. Reaction times (RT), detection sensitivity (d′), and symptoms were recorded for the three different viewing conditions. Results: RT and d’ were not affected by the viewing condition (p > 0.05). In contrast, symptoms significantly depended on the viewing condition but were, in part, not significantly affected by age. It is interesting to note that although not significant, young participants reported more ocular symptoms than older participants in the near vision task carried out using the HMD. Discussion: HMD increases visual symptoms. However, HMD could be, in part, a remedy to problems when using visual aids for near work, in particular for presbyopes.

  • Macular Corneal Dystrophy – Molecular Genetics as the Key in Treatment-Refractory Keratopathy
    Item type: Journal Article

    Macular corneal dystrophy (MCD) is a severe and rare form of corneal dystrophy. It usually develops in childhood or adolescence [1], [2] and is a genetic disorder with an autosomal recessive pattern of inheritance. MCD is characterized by the formation of progressive bilateral scattered gray-white punctuate opacities in the corneal stroma and central corneal thinning. It typically starts centrally, which then progressively extends to the periphery and eventually involves the entire corneal thickness. If left untreated, MCD leads to bilateral deterioration of visual acuity. Currently, the most effective treatment is corneal transplantation [1], [2]. Even though recurrence of MCD is rare, it may occur many decades after penetrating keratoplasty (PKP), which remains the gold standard in the cure of MCD for long-term visual rehabilitation.
  • Emergency Vitrectomies for Retinal Detachment Before and During the Coronavirus Pandemic – A Retrospective Single Centre Analysis
    Item type: Journal Article

    Klinische Monatsblätter für Augenheilkunde
    BACKGROUND: While the corona pandemic and the resulting containment measures affect the number of elective surgical procedures, the impact on emergency surgical interventions is less tangible. This analysis quantifies the frequency of emergency vitrectomies for retinal detachment and investigates underlying factors. METHODS: Retrospective identification of patients who underwent primary emergency vitrectomies for retinal detachment at the Cantonal Hospital of Lucerne between 01.01.2018 - 31.12.2020. Parameters were collected, including demographics, date of hospitalisation, reported onset of symptoms, pre-operative best corrected visual acuity (BCVA), involvement of the macula, and canton of residence. RESULTS: Overall, a total of 665 patients with 683 eyes underwent emergency surgery for primary retinal detachment in the time span of 01.01.2018 - 31.12.2020. Median monthly number of surgeries was 20. During the first Swiss national lockdown (16.03.2020 - 19.04.2020), a minimum of 9 vitrectomies was recorded in March 2020. A maximum of 36 vitrectomies was conducted in August 2020. The mean age of patients was 61.5 years. Of the 665 patients, 133 (20.0%) were residents of the canton of Ticino. Median pre-operative BCVA was 0.25 over all three years, and no significant reduction in pre-operative BCVA was observed during or after the lockdown. The proportion of eyes with involvement of the macula was 52.2%. In 2018, this proportion (47.6%) was significantly lower than in 2019 and 2020 (Chi2 test, p < 0.001). However, cases with macular involvement in post lockdown months were not more frequent. Median time in days from reported symptom onset to hospitalisation was 5 days. In April 2020, the proportion of patients with > 14 days symptom duration was significantly higher (Chi2 test, p < 0.001). During the lockdown, there was a significant reduction in cases from Ticino. Also, patients from Ticino showed proportionally longer symptom duration after the lockdown. CONCLUSION: A significant reduction in the number of emergency vitrectomies was observed for the initial period of the coronavirus pandemic. Delayed emergency presentation is not assumed, since there was no increase in severity (i.e. macular involvement) or prolonged symptoms in the months following the lockdown. More protracted symptoms were only observed in patients from Ticino. The initial low numbers were generally made good later in the year.

    Purpose Assessment of diagnostic and therapeutic strategies currently used in routine practice for myopia management in Europe. Methods Online survey study including 11 main questions. The questionnaire was sent to members of the European Paediatric Ophthalmology Society (EPOS). The following items and questions were surveyed: I. Profession and workplace of the survey participants. II. Preventive measures and recommendations for myopia management, a) regarding reading distance and near work, b) optical tools, i.e., application of Defocus Incorporated Multiple Segments (DIMS) glasses, near additions, or contact lenses, and c) the application of atropine eye drops. III. Application of additional diagnostic tools. Results Forty-eight individuals completed the survey. Of the respondents, 88% (n = 42) affirmed that they generally gave advice on strategies for myopia prevention and management strategies. Almost all study participants (n = 41; 85%) recommend outdoor time as a preventive measure. The recommendation on near distance is given less frequently, with 28 (58%) participants confirming that they do recommend a “safe” reading distance, and 15 (31%) negating this. Eight (17%) survey participants recommend using near addition glasses, while 36 (75%) do not. Similarly, 35 (73%) respondents do not apply DIMS glasses and 8 (17%) apply them. Fourteen (29%) participants recommend myopia-reducing contact lenses while 30 (63%) do not, and 29 (60%) confirmed that they applied atropine eye drops to slow myopia progression while 14 (29%) do not prescribe these eye drops. The majority of respondents (n = 25; 86%) who prescribe atropine eye drops use atropine 0.01% eye drops. Conclusions Prevention and therapeutic management of childhood myopia is an essential part in the daily routine of pediatric ophthalmologists. Substantial agreement was found for the protective role of outdoor time (85%). The only common therapeutic approach is the administration of atropine eye drops (60%).
