Purpose:
To investigate the outcomes of brolucizumab reinjection after intraocular inflammation (IOI) development.
Methods:
This retrospective study analyzed patients with brolucizumab injections from April 2021 to January 2024. Patients who developed IOI after brolucizumab were included and categorized into subgroups depending on reinjection, discontinuation, and further IOI development.
Results:
A total of 472 eyes of 432 patients received brolucizumab injections. Thirty-eight cases developed IOI at least once, and 25 continued brolucizumab. Sixteen cases had no more IOI events, and nine experienced a second or more IOI events. Among the nine cases, three maintained brolucizumab injections despite IOI recurrence. The incidence of IOI was 8.1% based on the number of eyes (38 of 472 eyes) and 2.0% based on the number of brolucizumab injections (50 of 2,468 injections). The incidence of occlusive retinal vasculitis was 0.2% (1 of 472 eyes). The recurrence rate was 23.7% (9 of 38 eyes). The average number of injections between the first brolucizumab injection and the injection date on which IOI first developed was 2.15 times in the no-reinjection group, 3.44 times in the no-IOI-recurrence group, and 2.0 times in the second-IOI-episode group. Time to IOI occurrence in cases with first IOI episode was 18.60 ± 16.73 days, with 15 cases developing IOI within 1 week.
Conclusions
This study elucidates the real-world incidence of brolucizumab associated IOIs, with a description of information related to reinjections after the IOI episodes. A comprehensive understanding of brolucizumab reinjection is essential for its optimal utilization.

Background/Aims:
The optimal treatment for acute malignant obstruction of the proximal colon (MOPC, proximal to the splenic flexure) remains challenging. Emergency resection, the traditional modality for MOPC, has shown significantly high mortality and morbidity rates, according to recent studies. This study aimed to investigate the clinical outcomes of stent vs stoma as a bridge to curative surgery for MOPC.
Methods:
This retrospective cohort study included 72 patients who underwent endoscopic placement of a self-expanding metallic stent (SEMS) or loop ileostomy for MOPC at six referral centers between January 2011 and July 2021. Clinical and pathological characteristics, procedure-related complications, and long-term mortality rates after curative surgery were analyzed.
Results:
During a mean follow-up period of 32 months, 30 patients (41.7%) underwent ileostomy preferentially for more proximal cancer, complete obstruction, and advanced tumor stage compared to the SEMS group. No difference was found in procedure-related complications, but five deaths were observed after ileostomy. Survival analysis for 5-year mortality after curative surgery showed no significant difference between the bridge modalities (log-rank p = 0.253).
Conclusions
In this study, SEMS as a bridge to surgery showed relatively safe results in terms of post-procedural mortality. However, these results should be considered when performing ileostomy in patients with more advanced malignant obstruction.

Purpose:
To assess the prevalence and progression of a stage 0 macular hole in the fellow eye of patients with an idiopathic full-thickness macular hole.
Methods:
The fellow eyes of 189 patients who underwent idiopathic full-thickness macular hole surgery were examined by biomicroscopy and spectral domain-optical coherence tomography (SD-OCT). A subset of 21 fellow eyes with a stage 0 macular hole was observed. Changes in the macular hole were evaluated by biomicroscopy and SD-OCT for an average of 29 months.
Results:
Among the 21 eyes, 15 showed no change in perifoveal vitreous detachment (71.4%). Two eyes (9.5%) developed complete vitreofoveal separation, and one of the two developed a separation after progression to stage 1A. Among 21 eyes, 5 (23.8%) developed above stage 1A, and one of the five progressed to stage 1B after five years, which was successfully treated with vitrectomy and gas tamponade.
Conclusions
Perifoveal vitreous detachment in the fellow eye on SD-OCT, defined as a stage 0 macular hole, occurred at an earlier phase than stage 1A macular holes and may progress to an advanced stage. Therefore, patients who undergo macular hole surgery and have a stage 0 macular hole or perifoveal vitreous detachment in the fellow eye should be followed closely.

Journal of the Korean Ophthalmological Society 2020;61(7):746-754
Purpose:
To assess the efficacy and safety of Adalimumab (Humira®, AbbVie, Chicago, IL, USA) for repeated refractory uveitis during systemic steroid or immunosuppressive therapy.
Methods:
We retrospectively reviewed clinical records on 30 eyes of 18 patients with non-infectious refractory uveitis who underwent Adalimumab injection therapy from December 2017 to July 2019. The therapeutic effect was assessed based on intraocular inflammation grade, central macular thickness, and best corrected visual acuity, and the efficacy was assessed based on control of inflammation and macular edema, as well as corticosteroid sparing effects. The safety was assessed based on adverse events.
Results:
The mean duration of uveitis at baseline was 55.4 months (13-121 months) and the mean follow-up was 9.2 months (6-18 months). All 30 eyes of 18 patients stopped using systemic steroids and maintained clinical quiescence. Anterior chamber inflammation, vitreous inflammation, and best corrected visual acuity showed significant improvement, and there was no difference in central macular thickness. Uveitis recurred in 5 eyes, but 4 eyes showed controlled inflammation after single posterior sub-tenon steroid injection. One eye was controlled after methotrexate co-administration. Ulticaria (two patients) and injection- site reaction (one patient) were reported as adverse events.
Conclusions
Adalimumab is an effective treatment for decreasing inflammatory activity and reducing corticosteroid burden in refractory uveitis.

OBJECTIVES:
The purpose of this study was to examine personality traits associated with suicidal symptoms (with history of suicide attempt or suicidal idea) in depressed patients.
METHODS:
A sample 186 patients diagnosed with major depressive disorder was divided into two groups : suicidal group (with history of suicide attempt or suicidal idea, n=70) and non-suicidal group (without history of suicide attempt or suicidal idea, n=116). NEO Personality Assessment System were used to evaluate personality trait.
RESULTS:
Neuroticism was high in suicidal group (p=0.041). In multivariate logistic regression, Neuroticism was also a significant influence on suicidal symptoms (Odds Ratio=1.04, 95% Confidence Interval 1.01–1.07, p=0.0145).
CONCLUSIONS
High Neuroticism is a useful information to identify individuals at high risk of suicide in depressive patients.
