Purpose: This study aimed to describe the choroidal features of ocular amyloidosis using multimodal imaging, to correlate these findings with systemic involvement, and to propose a choroidal grading system. Methods: Eleven patients with systemic amyloidosis were reviewed retrospectively. Each case was assigned a grade according to the severity of choroidal findings as determined by both enhanced depth imaging optical coherence tomography and indocyanine green angiography. The severity of systemic amyloidosis was then correlated with the choroidal involvement. Results: On indocyanine green angiography, all patients exhibited hyperfluorescent spots in the late stage and were classified according to preexisting criteria. On enhanced depth imaging optical coherence tomography, hyperreflective foci were seen in the choriocapillaris and Sattler's layer in Grade 1, partial loss of Sattler's layer was additionally seen in Grade 2, and a dense hyperreflective Haller's layer was seen in Grade 3. Choroidal grading scores were significantly correlated with the systemic severity score (P = 0.0014, Pearson's correlation coefficient; ρ = 0.83). Conclusion: With ocular amyloidosis, evaluation of choroidal characteristics using multimodal imaging may serve as a biomarker for systemic involvement.

Purpose: We sought to evaluate whether additional topical anesthetic, specifically proparacaine 0.5%, improved patient experience with intravitreal injections without hindering antisepsis. Methods: A prospective, randomized controlled trial was conducted including 36 eyes of 36 patients undergoing intravitreal injections. Patients were randomized to treatment with additional topical proparacaine 0.5% versus control after undergoing informed consent. All patients prior to intravitreal injection underwent conjunctival culture after one drop of topical proparacaine 0.5% was placed. Half of patients then received an additional drop of proparacaine and then underwent a second conjunctival culture. The other half of patients had a drop of povidone iodine and then a second conjunctival culture. Intravitreal injection followed conjunctival cultures. To evaluate their experience, patients were provided with a survey. Results: In total, 36 patients were enrolled in the study. Three of 36 (8.3%) patients had positive conjunctival cultures after proparacaine eye drops alone. One of 17 (5.8%) patients had a positive conjunctival culture after a second drop of proparacaine. One of 19 (5.3%) patients had a positive culture after proparacaine and povidone iodine. By noninferiority analysis, proparacaine was inferior to povidone iodine ( p = .28). Patient experience surveys did not differ between groups. Conclusion: Patient perception did not significantly differ whether or not additional proparacaine drops were used prior to intravitreal injection in a randomized controlled trial. While proparacaine has some antiseptic properties, these were found to be inferior to those of povidone iodine. Therefore, while povidone iodine is essential for antisepsis, additional proparacaine drops should not interfere with antisepsis.

Purpose: We aimed to describe the clinical and histologic findings in a few enucleation cases with intraocular lymphoma. Methods: Retrospective review of pathology files from a 22-year period identified cases with intraocular lymphoma among all enucleation specimens. Patient demographics, clinical findings, laboratory results, radiographic studies, and indication for enucleation were abstracted from electronic health records; slides were reviewed. Results: Four patients (three women and one man; age range, sixth through eighth decades of life) underwent enucleation with a final diagnosis of intraocular lymphoma. Two patients with primary vitreoretinal large B-cell lymphomas had been treated for refractory uveitis. Specimens showed retinal and subretinal infiltrates by atypical large B-lymphocytes and rare neoplastic cells in the vitreous. The remaining two patients had systemic lymphoproliferative disorders. One patient had chronic lymphocytic leukemia and floaters in his eye; vitreoretinal lymphoma developed, consistent with intraocular Richter transformation. The other had diffuse large B-cell lymphoma in remission; however, blurred vision developed, she was treated for panuveitis without improvement, and was later found to have ocular involvement by diffuse large B-cell lymphoma. Conclusion: Our series details the unusual circumstances when an eye is removed for intraocular lymphoma. Different patterns of ocular tissue involvement were observed when we compared primary and secondary lymphomas.

Abstract Introduction. Vitreoretinal lymphoma (VRL) is a rare ocular malignancy. Diagnosis and optimal treatment remain a challenge for clinicians. We present clinical characteristics and outcome of a cohort of 69 patients affected by vitreoretinal diffuse large B-cell (DLBCL) lymphoma treated at Mayo Clinic over a 28-year period. Methods. We accessed the Mayo Clinic Lymphoma Data Base to identify all patients > 18 years old with VRL diagnosed between 01/01/1990 and 01/31/2018. Only patients with DLBCL, confirmed at pathological review, were included. Clinical characteristics, therapies, response, relapse patterns and follow up status were collected and analyzed in the cohort and in the different subgroups: primary (PVRL, localized only in eye at diagnosis) vs concurrent (CVRL) vs secondary VRL (SVRL). Chi-squared test, Fisher's exact test and Wilcoxon's signed-rank test were used for analysis. Failure-free survival (FFS), overall survival (OS), central nervous system (CNS) and eye relapse-free survival were analyzed according to Kaplan Meier method. Differences between subgroups were compared with log-rank test. Since the group of SVRL can be affected by a survivorship selection bias, it was investigated separately for the outcome analysis. Results. A total of 69 patients with vitreoretinal DLBCL were included. At diagnosis, 33 (48%) were PVRL, 18 (26%) CVRL (eye plus CNS (N=17) or systemic (N=1) disease) and 18 (26%) had SVRL (9 primary CNS lymphomas, 9 systemic at diagnosis, among which 4 were primary testicular lymphomas). Unilateral intraocular involvement was observed in 16 (23%) cases. Clinical characteristics are reported in Table I. At diagnosis, patients received a systemic treatment in 35 (50%, including high-dose systemic MTX (HD-MTX, N 14, 20%), MTR (HD-MTX, Temozolomide and Rituximab) (N 7, 10%) and CHOP (Cyclophosphamide, Doxorubicin, Vincristine and Prednisone) with or without Rituximab (N 10, 15%)), combined systemic plus intraocular treatment in 15 (22%), local radiotherapy in 10 (14%) and intraocular therapy (intraocular injections of rituximab or MTX or steroids or a combination of these) in 9 (13%) cases. Systemic Rituximab, autologous stem cell transplantation (ASCT) and therapeutic vitrectomy/enucleation were performed in 36 (53%), 20 (29%) and 5 (7%) patients, respectively. The median number of treatments was 2 (range 0-10). Among PVRL and CVRL (N=51), median FFS, CNS relapse-free survival, eye relapse-free survival and OS were: 1.8 y, 4.9 y, 3.8 y and 4.1 y, respectively (Fig 1). Among PVRL they were: 2.6 y, not reached (NR), 5.2 y and 9.3 y, respectively. No CNS relapse occurred beyond 4 years in the PVRL subgroup. The median OS for patients diagnosed between 1990 and 1999, in contrast to 2000 and 2018 was 1.5 y vs 9.4 y respectively (p= 0.0002). OS was significantly higher in PVRL, as compared to CVRL (p= 0.04). Previous immunosuppression and poor performance status were predictive of worse outcome (p=0.04), while ASCT correlated with higher OS (p= 0.009). In PVRL, a combined systemic + intraocular therapy was associated with higher FFS (p=0.002) and CNS-relapse free survival (p= 0.003), but no difference in OS was observed. Among 18 SVRL, at a median follow-up of 1.1 y after vitreoretinal relapse, median FFS and OS were 0.3 y and 1.3 y, respectively. Systemic toxicities included 8 (11.6%) acute renal failures, 8 (11.6%) infections, and 3 (4.3%) hemorrhages. Intraocular toxicities included cataract in 11, vitreal detachment in 3 , ocular hypertension in 5, retinal vessel occlusion in 3 and keratitis in 2 cases. Of 69 patients, 39 (56.5%) died secondary to lymphoma (N=21, 53.8%), infectious toxicity (N=2, 5.2%), unrelated (N=3, 7.7%) or unknown (N=13, 33.3%) causes. Conclusions. VR DLBCL is a rare disease, which can occur as primary, concurrent with systemic, or in relapsed disease. OS over the decades has significantly improved. In PVRL, no late CNS relapses were observed, while late intraocular relapses can occur. A combined approach with intraocular + systemic HD-MTX based treatment at diagnosis was associated with a higher FFS and CNS-relapse free survival in PVRL and is recommended in bilateral involvement, even though no differences in OS were observed. Treatment consolidation with ASCT can be considered in cases with concurrent systemic disease. Further studies are needed to confirm these results and to better define the role of new drugs in treatment of this uncommon malignancy.

Purpose: To describe two patients with giant cell arteritis who presented with macular lesions mimicking persistent placoid maculopathy. Methods: Retrospective case reports. Patient: Two patients, a 74-year-old man and an 85-year-old woman both were diagnosed with biopsy-confirmed giant cell arteritis with vision loss in one eye due to arteritic ischemic optic neuropathy. Both presented many years later with acute vision loss in the remaining eye. Results: Both patients had bilateral retinal whitening in the parafovea, and the second also had sectoral optic disk swelling. On fluorescein angiography, these areas of retinal whitening in both patients were hypofluorescent early with late hyperfluorescence staining. On indocyanine green angiography, there were areas of foveal hypocyanescence bilaterally in both patients that persisted throughout the imaging and were more apparent late. These findings can be seen in patients with bilateral persistent placoid maculopathy. Conclusion: Giant cell arteritis should be included in the differential diagnosis of persistent placoid maculopathy.

Purpose: To describe a case of choroidal neovascularization (CNV) and chorioretinal scarring in a patient with melanoma-associated retinopathy after ipilimumab/nivolumab combination immune therapy for malignant melanoma. Methods: Retrospective case report with fundus photography, fluorescein angiography, optical coherence tomography, and electroretinography. Results: A 65-year-old woman presented with symptoms of photopsia and visual field loss. She had previously undergone ipilimumab/nivolumab combination chemotherapy treatment for malignant melanoma 14 months earlier coinciding with the onset of her visual symptoms. Fundus photography showed bilateral atrophic chorioretinal lesions and peripheral retinal pigment epithelial changes. Fluorescein angiography revealed retinovascular leakage in both eyes with CNV in the right eye. Optical coherence tomography showed a pigment epithelial detachment with subretinal fluid and subretinal hyperreflective material consistent with occult CNV. Visual field testing showed generalized visual field loss in both eyes. Bloodwork discovered an elevated angiotensin-converting enzyme. Electroretinography revealed abnormal peripheral rod and cone function with impairment of the photoreceptor and inner nuclear layer. Serum Western blot was positive for 60 kDa antiretinal autoantibody. After a single bevacizumab injection in the right eye, CNV resolved and visual acuity improved from 20/50 before the injection to 20/25 3 months after the injection. Visual acuity in the left eye deteriorated for months to counting fingers but then improved to 20/100 on follow-up examinations. Conclusion: Ipilimumab and nivolumab have been associated with immune-related ocular adverse effects. We report a case of combination therapy presenting with chorioretinal scarring and subsequent CNV in a patient with melanoma-associated retinopathy, a rare yet important adverse effect.

Purpose: To describe a novel fluorescein angiographic finding in patients with von Hippel–Lindau disease. Methods: Retrospective case series of patients diagnosed with retinal capillary hemangioblastoma (RCH) in the setting of von Hippel–Lindau. Results: We identified six eyes of three patients with von Hippel–Lindau and leaky retinal vessels. All eyes showed segmental diffuse vascular leakage (SDVL) that was seen in the late phase of the angiogram and that originated from third order and more peripheral retinal veins and adjacent capillaries. These vessels did not drain from the RCHs. Segmental diffuse vascular leakage was mainly seen in the mid and far periphery. In some cases, it was located near the RCHs, while in other cases, it was remote. Segmental diffuse vascular leakage was also seen in one eye without RCHs. On follow-up, the extent and intensity of segmental diffuse vascular leakage did not change after the RCHs were treated with laser or cryotherapy. Conclusion: Diffuse vascular leakage from retinal venules around and away from RCHs in patients with von Hippel–Lindau disease is seen, but the clinical and prognostic importance of this finding is uncertain.

Introduction: Antineutrophil cytoplasm antibody-associated vasculitides encompass a diverse spectrum of autoimmune diseases characterized by necrotizing small vessel vasculitis. Ocular manifestations may be the presenting findings of antineutrophil cytoplasm antibody-associated vasculitides. Methods: Single, retrospective case study. Results: We report the rare case of a 55-year-old woman with a cilioretinal artery occlusion as the presenting feature of perinuclear antineutrophil cytoplasm antibody-associated microscopic polyangiitis. Conclusions: Although rare, antineutrophil cytoplasm antibody-related vasculitis should be considered in any retinal vascular occlusion, particularly in the setting of patients with new vague headaches and a paucity of vasculopathic risk factors.
