Epstein-Barr viral corneal stromal keratitis occurring during rheumatoid arthritis treatment: a case report.

BACKGROUND: A case of Epstein-Barr viral (EBV) corneal stromal keratitis during rheumatoid arthritis (RA) treatment is presented. CASE PRESENTATION: A 74-year-old female undergoing RA treatment was previously treated for bacterial corneal ulcer and herpetic keratitis and healed with antibiotic eye drops and topical anti-herpes ointment. At the first visit to our hospital, she presented with findings of monocular posterior interstitial keratitis with neovascularization mostly located in the inferior cornea with a corneal epithelial defect. The right eye showed no thinning of the corneal periphery and anterior uveitis. Her RA had subsided with oral steroid treatment, and infectious mononucleosis (IM) had not developed. EBV DNA could be detected in her corneal sample. After an extended but ineffective period to antibiotic treatment the corneal infiltrate responded rapidly to topical corticosteroids. CONCLUSION: EBV can cause stromal keratitis without IM during treatment for RA.

Annular choroidal detachment following intravitreal aflibercept injection in a patient with nivolumab treatment: a case report.

BACKGROUND: To present a novel case that developed annular choroidal detachment after intravitreal anti-vascular endothelial growth factor antibody injection in a patient after immune checkpoint inhibitor treatment. CASE PRESENTATION: A 58-year-old Japanese man presented visual impairment in the right eye. Ophthalmological examination revealed macular edema in the right eye, which suggested the possibility of age-related macular degeneration. Following the intravitreal aflibercept injection, the annular choroidal detachment was observed in the injected eye. As hypotony or thick sclera was not observed, choroidal detachment seemed to have appeared due to enhanced inflammation by intravitreal injection. The patient had a history of stage IV paranasal cavity cancer and was treated with nivolumab, an immune checkpoint inhibitor. The immune response might have been enhanced due to the use of nivolumab so that intravitreal injection triggered inflammation. Three weeks after sub-tenon injection of triamcinolone acetonide, macular edema and choroidal detachment improved. CONCLUSIONS: Intravitreal aflibercept injection caused annular choroidal detachment in our patient, presumably because the immune system was activated after nivolumab treatment. To the best of our knowledge, this is the first case report of annular choroidal detachment that developed after intravitreal injection in a patient with a history of nivolumab therapy. With the increasing use of immune checkpoint inhibitors in patients with various cancers, clinicians should be aware of these potentially associated immune-related adverse events.

Adjustment of intraocular lens tilt during intrascleral fixation assisted by intraoperative OCT.

PURPOSE: To evaluate the efficacy of using intraoperative optical coherence tomography (iOCT) to adjust the tilting of an intraocular lens (IOL) during implantation with intrascleral fixation. SETTING: Kyorin University Hospital, Tokyo, Japan. DESIGN: Retrospective, case-control, single-center study. METHODS: Thirty-seven eyes of 37 patients who had undergone pars plana vitrectomy with intrascleral fixation of an IOL by a single surgeon were retrospectively studied. The length of the externalized haptics was determined when the anterior surface of the IOL was parallel to the plane of the iris as observed by iOCT. The maximal IOL tilt relative to the visual axis and to the iris plane was measured by anterior segment OCT (CASIA2; Tomey Corp.). RESULTS: Intraoperative crosssectional OCT (RESCAN 700: Carl Zeiss Meditec AG) scans were used to adjust the degree of IOL tilt in 23 eyes (iOCT group) and not used in 14 eyes (control group). The maximal angle of IOL tilt relative to the visual axis was significantly smaller in the iOCT group than that in the control group (5.45 ± 2.63 degrees vs 10.38 ± 10.48 degrees, P = .034). The maximal angle of the IOL tilt to the iris plane was also significantly smaller in the iOCT group than that in the control group (4.58 ± 1.86 degrees vs 9.60 ± 10.82 degrees; P = .040). The distance of decentration was greater in the iOCT group (0.56 ± 0.29 mm) than that of the control group (0.41 ± 0.41 mm, P = .005). CONCLUSIONS: Intraoperative OCT can be used to adjust the degree of IOL tilt to reduce the lenticular astigmatism during intrascleral fixation surgery.

Case of peripheral fibrovascular proliferative retinopathy associated with morning glory disc anomaly.

It is known that the retinal detachments (RDs) associated with a morning glory disc anomaly (MGDA) usually appear from around the disc anomaly and complications by peripheral fibrovascular proliferation and tractional RD are very rare. We report our findings in an eye with MGDA that had a tractional RD, massive exudation from a peripheral temporal fibrovascular proliferation and vasculatures stretched by this proliferation and by a contraction of the hyaloidal membrane. The RD was successfully treated by vitrectomy and encircling buckling surgery.
