Purpose: We report a case of antineutrophil cytoplasmic antibody (ANCA)-associated optic neuritis with glomerulonephritis.Case summary: A 66-year-old male with a history of acute kidney injury presented with decreased visual acuity in both eyes. His best-corrected visual acuity (BCVA) was 0.15 in the right eye and 0.6 in the left eye. Both eyes showed optic disc swelling and Ishihara’s tests were 1/17. He was treated with intravenous methylprednisolone for 3 days to treat presumed bilateral optic neuritis. In follow-up, anti-myeloperoxidase antibody (anti-MPO antibody, p-ANCA) was positive at 32.0 IU/mL and ANCA-associated chronic sclerosing glomerulonephritis was found in the left kidney biopsy. He is currently being followed-up on oral steroids in the outpatient clinic. Kidney function improved immediately after high-dose steroid therapy. After 3 months of treatment, optic disc swelling resolved. On the other hand, there was minimal improvement in visual acuity. Conclusions In ANCA-associated optic neuritis with glomerulonephritis, both optic disc swelling and kidney function improved with steroid therapy. On the other hand, there was only a small improvement in visual acuity.

Purpose: To investigate clinical factors affecting subfoveal choroidal thickness (SFCT) and choroidal vascularity index (CVI) after cataract surgery. Methods: A retrospective medical record review was performed of 62 patients (95 eyes) who underwent cataract surgery. The SFCT and CVI were calculated based on cross-section measurements obtained from enhanced depth imaging-optical coherence tomography preoperatively and postoperatively at 1 week, 1 month, and 2 months. The changes in SFCT and CVI were analyzed with respect to anesthesia, diabetes mellitus (DM), hypertension (HTN), and phaco power/time. Results: Regardless of anesthesia, DM, or HTN, SFCT had increased at 1 week postoperatively and continued to decrease up to 2 months postoperatively. In the case of topical anesthesia and patients without DM or HTN, the CVI was significantly higher at 1 month postoperatively, but was followed by a steady reduction up to the 2-month follow-up. In the case of retrobulbar anesthesia and patients with DM or HTN, the CVI increased up to 2 months postoperatively. Conclusions In this study, clinical factors had a significant impact on the change in CVI after surgery, but not on the SFCT. This suggests that the presence of DM affects the change in the choroidal vessels after cataract surgery.
