Immunomodulatory Treatment Versus Systemic Steroids in Inflammatory Choroidal Neovascularization Secondary to Idiopathic Multifocal Choroiditis.

PURPOSE: To evaluate the influence of immunomodulatory therapy (IMT) on visual and treatment outcomes of inflammatory choroidal neovascularization (iCNV) in patients affected by multifocal choroiditis (MFC), and to compare them to patients treated with steroids as needed. DESIGN: Multicenter retrospective matched cohort study. METHODS: Patients affected by MFC with iCNV were divided into a IMT group and a "steroids as needed" group and matched according to the time between diagnosis and beginning of systemic treatment. Visual acuity (VA), number of anti-vascular endothelial growth factor (VEGF) intravitreal injections, and number of iCNV reactivations during 2 years of follow-up after treatment initiation were compared between the 2 groups. RESULTS: A total of 66 eyes of 58 patients were included, equally divided into the 2 groups. Patients in the IMT group had a lower relative risk (RR) of iCNV reactivation (0.64, P = .04) and of anti-VEGF intravitreal injection retreatment (0.59, P = .02). Relapses of MFC-related inflammation were independently associated with a higher RRs of iCNV reactivation (1.22, P = .003). Final VA was higher in the IMT compared to the steroids as needed group (mean [SD], 69.1 [15.1] vs 77.1 [8.9] letters, P = .01), and IMT was associated with greater VA gains over time (+2.5 letters per year, P = .04). CONCLUSIONS: IMT was associated with better visual and treatment outcomes in MFC complicated by iCNV compared to steroids as needed. The better outcomes of the IMT group and the association between MFC-related inflammation and iCNV reactivations highlight the need for tighter control of inflammation to prevent iCNV relapses and visual loss.

Case report: Surgical management of vitreous obstruction following PreserFlo ® MicroShunt implantation.

Purpose: To describe a clinical case of lumen obstruction a few days after implantation of the PreserFlo® Microshunt which has been resolved by anterior vitrectomy. Observation: A 76-year-old patient with advanced and progressing primary open-angle glaucoma (POAG) presented ten days after PreserFlo® Microshunt implantation in his left eye with an intraocular pressure (IOP) of 24 mmHg because of vitreous obstruction. Anterior vitrectomy with 25 Gauge vitrector was performed to remove the vitreous using a bimanual technique with two corneal accesses. The surgery was successful in lowering uncontrolled IOP without device repositioning. A free lumen and a IOP in the low range of tens was observed during follow-up. Conclusions and importance: PreserFlo ® MicroShunt obstruction by vitreous in pseudophakic patient is a possible complication. Anterior vitrectomy without the need of tube repositioning was successful in lowering uncontrolled IOP.

Utility of Anterior Segment OCT in the Management of Uveitic Cataract Surgery: A Fibrinoid Syndrome Case Treated with rtPA.

PURPOSE: To highlight the importance of swept-source anterior segment optical coherence tomography (SS-ASOCT) in the peri-surgical management of cataract in uveitis. To describe a case of fibrinoid syndrome in uveitis treated with recombinant tissue plasminogen activator (rtPA). METHODS: SS-ASOCT was performed at each follow-up before and after cataract surgery to assess anterior chamber inflammation and assist the clinical management of the patient. RESULTS: A patient with idiopathic autoimmune uveitis was scheduled for cataract surgery. SS-ASOCT allowed to correctly plan the surgery timing. The patient developed a severe fibrinoid syndrome. Postsurgical SS-ASOCT allowed to distinguish between anterior chamber cells and fibrin thus guiding the timing for rtPA intracameral injection. Visual acuity improved from 20/400 the day after the surgery to 20/40. CONCLUSION: SS-ASOCT allowed a precise assessment of the inflammatory components (cellular vs fibrinoid) after cataract surgery. Intracameral rtPA was safe and effective in the treatment fibrinoid syndrome in uveitis.
