Diffuse Unilateral Subacute Neuroretinitis

A 45-year-old woman presented with diminished vision in the left eye. Visual acuity was 6/9 and fundus showed a very large live nematode near the macula along with inflammatory outer retinal lesions in the periphery. We diagnosed the case as diffuse unilateral subacute neuroretinitis and treated with immediate focal photocoagulation of the worm along with oral antihelminthic drugs and corticosteroids. The report highlights the importance of prompt laser and steroids in achieving good structural as well as the functional outcome, and the added significance of advanced imaging techniques in prognosticating such patients.

PurposePeripheral exudative haemorrhagic chorioretinopathy (PEHCR) is a rare disorder that is often misdiagnosed. The aim of this study was to better characterise PEHCR and to assess treatment options.Material and methodsRetrospective multicentric chart review.ResultsOf 84 eyes (69 patients) with PEHCR referred between 2005 and 2017, the most common referral diagnosis was choroidal melanoma (41.3%). Bilateral involvement was found in 21.7% of cases. Haemorrhagic retinal pigment epithelium detachment was the most common peripheral lesion (53.6%). Maculopathy was associated with peripheral lesions in 65.8% of cases. PEHCR lesions were mostly heterogeneous (58.8%) on B-scan ultrasonography. Choroidal neovascularisation was found in 10 eyes (26.3%) out of 38 eyes that underwent fluorescein angiography. Polyps were observed in 14 eyes (58.3%) out of 24 eyes that underwent indocyanine green angiography. Fifty-one eyes were treated (62.2%). Intravitreal injections (IVTI) of antivascular endothelial growth factor (VEGF) were the most used treatment (36.6%) before laser photocoagulation, photodynamic therapy, vitrectomy and cryotherapy. Only vitrectomy improved visual acuity. Most lesions (65.6%) regressed at the last follow-up visit.ConclusionIn case of PEHCR, multimodal imaging is useful to avoid misdiagnosis, to characterise PEHCR lesions and to guide treatment strategies. Regression of PEHCR lesions was observed in two-thirds of the patients. Vitrectomy improved visual acuity. More than a third of patients underwent anti-VEGF IVTI. Further studies are needed to assess IVTI’s efficacy.

Radiologists play a central role in the diagnosis, initial staging, follow-up, and restaging of patients with myeloma. This review article attempts to familiarize the reader with all the various types of myeloma, their imaging appearances and useful imaging strategies. The staging system for myeloma patients has been updated and now includes findings from advanced imaging modalities. Radiologists have a vast array of imaging modalities at their disposal to aid them in diagnosis, staging, and follow-up. Currently, conventional radiographic skeletal surveys, magnetic resonance imaging, and F-18 FDG PET/CT examinations are the most useful instruments.

Purpose: To describe a case of macular telangiectasia type 2 (MacTel) presenting with decreased vision due to intraretinal/sub-internal limiting membrane (ILM) hemorrhage in the absence of neovascularization. Method: Clinical examination and multimodal imaging were performed. Results: A 65-year-old female presented with blurred left vision, recording 20/160 in that eye. There was intraretinal hemorrhage at the left macula centrally, with sub-ILM hemorrhage superiorly and inferiorly. Optical coherence tomography (OCT) showed no evidence of subretinal neovascularization. Imaging of the right macula was consistent with MacTel. The blood spontaneously cleared and the left visual acuity gradually improved to 20/25 by 4 months. Fluorescein angiography confirmed MacTel, and once the hemorrhage resolved, both inner and outer retinal cavitation was identified on OCT of the left macula. The left best-corrected visual acuity remained at 20/25 at 2-year follow-up. Conclusion: Spontaneous resorption of hemorrhage was accompanied by visual improvement.

We report an unprecedented case of a young patient with epilepsy coexisting with acute zonal occult outer retinopathy (AZOOR), a rare white dot syndrome of unknown etiology, associated with damage to the large zones of the outer retina. Recently, it has been established that epileptic episodes contribute to an inflammatory response both in the brain and the retina. A 13-year-old male patient with epilepsy was referred by a neurologist for an ophthalmologic consultation due to a sudden deterioration of visual acuity in the left eye. The examination, with a key role of multimodal imaging including color fundus photography, fluorescein angiography, indocyanine green angiography (ICGA), fundus autofluorescence (FAF), swept-source optical coherence tomography (SS-OCT) with visual field assessment, and electroretinography indicated AZOOR as the underlying entity. Findings at the first admission included enlargement of the blind spot in visual field examination along a typical trizonal pattern, which was revealed by FAF, ICGA, and SS-OCT in the left eye. The right eye exhibited no abnormalities. Seminal follow-up revealed no changes in best corrected visual acuity, and multimodal imaging findings remain unaltered. Thus, no medical intervention is required. Our case and recent laboratory findings suggest a causative link between epilepsy and retinal disorders, although this issue requires further research.

Purpose: To report a case of non-paraneoplastic autoimmune retinopathy (npAIR) treated with intravenous immunoglobulin (IVIG). Case report: A 12-year-old boy presented with progressive visual field loss, nyctalopia, and flashing for three months. He had suffered from common cold two weeks before the onset of these symptoms. On the basis of clinical history and paraclinical findings, he was diagnosed with npAIR, and IVIG without immunosuppressive therapy was started. During the one-year follow-up period after the first course of IVIG, flashing disappeared completely. Visual acuity remained 10/10, but nyctalopia did not improve. Multimodal imaging showed no disease progression. Conclusion: Although established retinal degenerative changes seem irreversible in npAIR, IVIG may be a suitable choice to control the disease progression.

Introduction: Target mismatch (TMM) identifies salvageable penumbra independent of time from stroke onset. Current guidelines do not recommend advanced imaging to select patients for mechanical thrombectomy (MT) within 6 hours after onset but indicate that more research is needed. To address this question, we designed a prospective multicenter cohort study to compare the rate of functional neurological recovery (mRS ≤2 @ 3 months) in patients treated by MT for ICA/M1/M2 occlusions within 6 hours after onset according to the presence of a TMM on baseline imaging. Hypothesis: 60% of patients with TMM vs. 35% of no TMM, would achieve an mRS≤2 at 3 months. Sample size calculation: 200 patients. Methods: Consecutive patients eligible for MT within 6 hrs after onset, who underwent CTP or DWI/PWI imaging before treatment were enrolled. No NIHSS or ASPECTS restrictions were applied. Treating teams were blinded of CTP/DWI/PWI maps. mRS at 3 months was rated by an investigator blinded to clinical/imaging/treatment information. Automatically processed maps by RAPID software were reviewed after the end of follow-up. TMM definition followed EXTEND-IA criteria: MM volume >10mL, MM ratio>1.2, Core volume <70 mL. Mismatch (MM) was defined by MM ratio>1.2 and MM volume>10 mL. Imaging-based subgroups (TMM vs. No TMM) were defined after the end of follow-up. Results: 218 patients were enrolled. Baseline imaging profile distribution was 71% TMM, 29% no TMM, (in the no TMM group, 76% had a core volume > 70 mL); 82% MM and 18% no MM. Reperfusion(TICI 2B-3) was achieved in 86% of the patients after a median delay of 4.4 hrs (95%CI 3.6-5.9). 61% of the patients in the TMM group vs. 35% in the no TMM group had an mRS ≤2 @ 3 months, p<0.001 (adjustment for age, onset to reperfusion, NIHSS, reperfusion and baseline imbalances). Reperfusion vs. no reperfusion was associated with an increased rate of good outcome in the TMM and MM groups (61% vs. 38% p=0.039 and 60% vs. 32%, p=0.016) but not in the no TMM or No MM groups (35% vs. 33%, NS; 35 vs. 45%., NS). Conclusion: Patients with salvageable penumbra on advanced imaging experienced a larger benefit from MT than those without. Patients with no penumbra did not appear to benefit from reperfusion.

Aim.To study predictive factors for functional outcome of aflibercept intravitreal antiangiogenic therapy in patients with neovascular age-related macular degeneration (nAMD). Material and methods.Thirty-six treatment naive nAMD patients (45 eyes, 26 females and 10 males, with a mean age of 74.4 10.9 years) were included in this study. All patients received 3 monthly aflibercept injections followed by 4 bimonthly aflibercept injections. Demographic characteristics, baseline best corrected visual acuity (BCVA), central retinal thickness (CRT), and structural retinal changes on optical coherence tomography (OCT) scans were evaluated for the correlation with BCVA after 10 months follow-up. Results.At the end of the follow-up period, the mean BCVA increased statistically significantly from 31 15 (~0.32) letters at baseline to 37 14 (~0.4) letters (p= 0.003). CRT at baseline and at the end of follow-up was 357 110 and 269 70 m (p 0.001), respectively. Final BCVA correlated statistically significantly with baseline BCVA (r= 0.62,p 0.0001), baseline CRT (r= 0.48,p= 0.001), and disease duration from the appearance of complaints until the therapy start (r= 0.32,p= 0.03). Structural macular changes on the OCT scans were not related to final BCVA (p 0.05) apart from the status of the ellipsoid zone (p 0.001). Final BCVA was statistically significantly lower in males than in females (34.7 14.0 (~0.4) and 45.0 9.2 (~0.63) letters, respectively,p= 0.03). Conclusion.Baseline visual acuity, gender, CRT, disease duration from the appearance of complaints until the therapy start, and status of the ellipsoid zone are predictive for the functional outcome in wet AMD patients.

Purpose: This work reports a case of serpiginous choroiditis (SC) in association with ulcerative colitis and Clostridium difficile infection. Methods: A case report is discussed. Results: A 35-year-old man with a history of ulcerative colitis and recently treated C difficile infection presented with a rapid decline in central visual acuity in both eyes. Examination findings included geographic creamy-white lesions extending from the peripapillary region in both eyes. Multimodal imaging and negative infectious workup results supported the diagnosis of SC. Visual acuity and examination findings improved after initiation of systemic prednisone therapy. Adalimumab was initiated as a steroid-sparing treatment. At the last follow-up, 5 months after the initial presentation, SC and ulcerative colitis both remain in remission. Conclusions: SC has been previously described in patients with systemic disorders, including autoimmune conditions. This patient developed SC following C difficile infection and in the context of active ulcerative colitis. To our knowledge, this is the first report of SC in association with these entities.
