Presentation of Graves' orbitopathy within European Group On Graves' Orbitopathy (EUGOGO) centres from 2012 to 2019 (PREGO III).

BACKGROUND: Graves' orbitopathy (GO) is subject to epidemiological and care-related changes. Aim of the survey was to identify trends in presentation of GO to the European Group On Graves' Orbitopathy (EUGOGO) tertiary referral centres and initial management over time. METHODS: Prospective observational multicentre study. All new referrals with diagnosis of GO within September-December 2019 were included. Clinical and demographic characteristics, referral timelines and initial therapeutic decisions were recorded. Data were compared with a similar EUGOGO survey performed in 2012. RESULTS: Besides age (mean age: 50.5±13 years vs 47.7±14 years; p 0.007), demographic characteristics of 432 patients studied in 2019 were similar to those in 2012. In 2019, there was a decrease of severe cases (9.8% vs 14.9; p<0.001), but no significant change in proportion of active cases (41.3% vs 36.6%; p 0.217). After first diagnosis of GO, median referral time to an EUGOGO tertiary centre was shorter (2 (0-350) vs 6 (0-552) months; p<0.001) in 2019. At the time of first visit, more patients were already on antithyroid medications (80.2% vs 45.0%; p<0.001) or selenium (22.3% vs 3.0%; p<0.001). In 2019, the initial management plans for GO were similar to 2012, except for lid surgery (2.4% vs 13.9%; p<0.001) and prescription of selenium (28.5% vs 21.0%; p 0.027). CONCLUSION: GO patients are referred to tertiary EUGOGO centres in a less severe stage of the disease than before. We speculate that this might be linked to a broader awareness of the disease and faster and adequate delivered treatment.

Dual platelet inhibition in cases of severe retrobulbar hemorrhage following retrobulbar and peribulbar anesthesia.

PURPOSE: To evaluate the prevalence of dual platelet inhibition in cases of severe retrobulbar hemorrhage following retrobulbar and peribulbar anesthesia. SETTING: Department of Ophthalmology, Ludwig-Maximilans Universität, München, Germany. DESIGN: Retrospective study. METHODS: Two groups of patients were screened retrospectively over a 5-year period for the inclusion criterion of severe retrobulbar hematoma after retrobulbar or parabulbar injection. The first group consisted of emergency cases referred to the clinic. A second group of patients had received retrobulbar block at the hospital. All cases were collected and screened for the presence of antiplatelet therapy. RESULTS: Among roughly 160 000 patient records screened, 3 patients with grade IV retrobulbar hematoma were identified. Two of these patients were taking dual antiplatelet medications and 2 were on anticoagulation therapy during the time of retrobulbar or peribulbar anesthesia. None of the cases showed single medication platelet inhibition. The visual acuity of all patients stayed low at the 6-month follow-up (1.2 logMAR in 1 patient and no light perception in 2 patients). CONCLUSIONS: Retrobulbar hematoma is a rare but severe complication of retrobulbar anesthesia. With the high prevalence of dual platelet inhibition found in these cases, a prospective controlled trial seems unethical. In these high-risk patients, surgery should be performed under topical anesthesia if possible or general anesthesia if necessary.
