Abstract

Purpose

The effect of body mass index (BMI) and central fat distribution (CFD) reduction after bariatric surgery on ocular refraction is not well established. We assessed association between anthropometric parameters and refraction errors with other ocular and metabolic parameters 1 year after the surgery.

Materials and Methods

This was a retrospective study with patients underwent bariatric surgery and had at least 1 year follow-up. Data were extracted from the bariatric and ophthalmology outpatient clinic records of the participants. Measurements of metabolic, anthropometric, and ocular parameters including BMI, CFD, refraction status, visual acuity, intraocular pressure (IOP), optic coherence tomography (OCT), and biometry test of the eyes were evaluated.

Results

Seventy-four eyes of 37 patients had a mean follow-up of 14.4 ± 1.7 months after the surgery. Mean BMI and percentage of CFD decreased from 47.5 ± 6.7 to 33.1 ± 5.2 kg/m2 (p < 0.01) and 28.5 ± 5.74 to 17.8 ± 4.64 (p < 0.001) after 1 year, respectively. Mean refractive errors of the right and left eyes changed from − 0.62 ± 1.23 D to − 0.17 ± 1.36 D and from − 0.79 ± 1.39 to − 0.34 ± 1.56 after 1 year of the surgery (p < 0.001). Mean IOP was significantly reduced (p < 0.001). Unlike BMI, reduction in CFD was significantly correlated with refraction change in both eyes (right eyes; r = 0.783, left eyes; r = 0.791, p < 0.001) after 1 year. No significant differences were found in the other parameters.

Conclusion

Bariatric surgery induced significant refractive change in eyes, which is significantly associated with CFD reduction after 1 year. Bariatric surgery should be considered as a risk factor in patients with unexpected refractive error changes.

Nur selten ernste Komplikationen bei endoskopischer Sinuschirurgie

Etwa 3% der Menschen mit einer endoskopischen Nasennebenhöhlenoperation entwickeln ausgeprägtes Nasenbluten. Andere Komplikationen, wie Verletzungen des Nervus opticus oder eine Meningitis, treten nur äußerst selten auf, legt eine Registeranalyse nahe.

Hochrisiko-Spinaliom am besten mit der Mohs-Chirurgie entfernen

Die Mohs-Chirurgie ist zwar mit mehr Aufwand verbunden als die herkömmliche Exzision; für die Versorgung kutaner Hochrisiko-Plattenepithelkarzinome lohnt sich die zeitintensive Technik aber in jedem Fall. Laut einer aktuellen Studie sinkt im Vergleich das Sterberisiko.

Mechanische Herzklappe beschert jüngeren Betroffenen längeres Leben

Patienten und Patientinnen bevorzugen bioprothetische Herzklappen gegenüber mechanischen Klappenprothesen. Diese Wahl könnte sich zumindest für jüngere Patienten nachteilig auswirken: Ihnen bietet eine mechanische Klappe anscheinend einen Überlebensvorteil.

Darmpolyp weg – Peptid-Gel gegen Nachblutungen drauf?

Das Nachblutungsrisiko nach einer endoskopischen Mukosaresektion von flachen kolorektalen und duodenalen Adenomen war in der deutschen PURPLE-Studie mit einem hämostatischen Gel nicht kleiner als ohne Prophylaxe.
