Purpose: This article characterizes widefield fundus autofluorescence (WF-FAF) patterns in retinoschisis (RS), retinal detachment (RD), and combined retinoschisis-detachment (RS/RD), and to correlate them with spectral-domain optical coherence tomography (SD-OCT) findings. Methods: A retrospective case series of 13 eyes with senile RS, RD, or RS/RD is presented. One eye underwent imaging of 2 areas within the retina, resulting in 14 data points. Independent, masked graders classified pathology on SD-OCT as RS, RD, or RS/RD and graded WF-FAF images for either hypoautofluorescent areas or mixed autofluorescence (AF) (hyper-AF, iso-AF, hyper-AF with hypo-AF, hyper-AF with iso-AF, or hypo-AF with iso-AF). Results: There was no statistically significant correlation between the autofluorescence pattern and the type of retinal abnormality ( P = .74). Conclusions: High variability was found in the characterization of WF-FAF in patients with RS and RD. SD-OCT remains the criterion-standard imaging modality in distinguishing RS from RD in clinically ambiguous cases.

Background and Aim. Lung ultrasound (LUS) is a convenient imaging modality in the setting of coronavirus disease-19 (COVID-19) because it is easily available, can be performed bedside and repeated over time. We herein examined LUS patterns in relation to disease severity and disease stage among patients with COVID-19 pneumonia. Methods. We performed a retrospective case series analysis of patients with confirmed SARS-CoV-2 infection who were admitted to the hospital because of pneumonia. We recorded history, clinical parameters and medications. LUS was performed and scored in a standardized fashion by experienced operators, with evaluation of up to 12 lung fields, reporting especially on B-lines and consolidations. Results. We included 96 patients, 58.3% men, with a mean age of 65.9 years. Patients with a high-risk quick COVID-19 severity index (qCSI) were older and had worse outcomes, especially for the need for high-flow oxygen. B-lines and consolidations were located mainly in the lower posterior lung fields. LUS patterns for B-lines and consolidations were significantly worse in all lung fields among patients with high versus low qCSI. B-lines and consolidations were worse in the intermediate disease stage, from day 7 to 13 after onset of symptoms. While consolidations correlated more with inflammatory biomarkers, B-lines correlated more with end-organ damage, including extrapulmonary involvement. Conclusions. LUS patterns provide a comprehensive evaluation of patients with COVID-19 pneumonia that correlated with severity and dynamically reflect disease stage. LUS patterns may reflect different pathophysiological processes related to inflammation or tissue damage; consolidations may represent a more specific sign of localized disease, whereas B-lines seem to be also dependent upon generalized illness due to SARS-CoV-2 infection.

This study is for reporting the outcomes of internal limiting membrane (ILM) peeling on persistent submacular fluid (PSF) after otherwise successful pars plana vitrectomy (PPV) for diabetic tractional retinal detachment (TRD). In this retrospective case series, five consecutive patients (5 eyes) who exhibited PSF following successful repair of diabetic TRD were included. The second operation was performed to remove ILM. The area of ILM peeling was expanded up to the major vascular arcade. Only air tamponade was used. The median interval between the first PPV and the second PPV with ILM peeling was 4.8 months (range: 4–6 months). PSF resolved completely within one (2 eyes) or 2 months after ILM peeling. The median logMAR best-corrected visual acuity (BCVA) was improved from 1.00 (Snellen equivalent 20/200) to 0.70 (Snellen equivalent 20/100). In conclusion, wide ILM peeling is an effective treatment option for PSF subsequent to successful repair of diabetic TRD. ILM peeling might increase the elasticity of retina, thereby allowing the retina to flatten. This procedure can induce faster retinal reattachment in diabetic TRD involving the macula.

Tumor Thrombi

Tumors of adrenal and thyroid glands have been associated with vascular invasions—so-called tumor thrombi, both in humans and dogs. The detection and characterization of venous thrombi is an important diagnostic step in patients with primary tumors for both surgical planning and prognosis. The aim of this study was to describe the use of contrast-enhanced ultrasonography (CEUS) for the characterization of tumor thrombi. Dogs with tumor thrombus who underwent bi-dimensional ultrasound (B-mode US) and CEUS were included. Seven dogs were enrolled in this retrospective case series. On B-mode US, all thrombi were visualized, and vascular distension and thrombus-tumor continuity were seen in three and two cases, respectively. On color Doppler examination, all thrombi were identified, seemed non-occlusive and only two presented vascularity. On CEUS, arterial-phase enhancement and washout in the venous phase were observed in all cases. Non-enhancing areas were identified in the tumor thrombi most likely representing non-vascularized tissue that could potentially be embolized in the lungs after fragmentation of the tumor thrombi. On the basis of these preliminary study, CEUS appeared to be useful for the characterization of malignant intravascular invasion.

Background/AimsA subset of patients with X linked retinoschisis (XLRS) have bullous schisis cavities in the peripheral retina. This study describes the characteristics and prognosis of the bullous form of XLRS.MethodsA retrospective case series was performed of nine patients with molecularly proven bullous XLRS seen at a single tertiary centre.ResultsAll cases of bullous peripheral schisis were bilateral, with one unilateral case at presentation which developed into bilateral bullous schisis over time. The mean age of onset was 1.9 years (range: 1 month–7 years, SD: 2.1 years) and at clinical diagnosis was 5.9 years (range: 1 month–27 years, SD: 9.0 years). Mean follow-up was 11 years (range: 6 months–36 years, SD: 10.8 years). Strabismus was the most common presentation (n=7). Other presenting complaints included decreased vision, floaters and an irregularly shaped pupil. The most frequently associated ocular features were strabismus (100%), vitreous haemorrhage (4/18 eyes, 22%), nystagmus (2/9, 22%) and persistent fetal vasculature (1/18, 6%). Localised tractional detachment was seen in 2/18 (11%) eyes, total detachment that underwent surgical repair in 1/18 (6%) and pigmented demarcation lines in a further 22% of the eyes. There was one eye with exudative retinal detachment.ConclusionIn XLRS, bullous schisis may be congenital or develop soon after birth and most commonly presents with strabismus. Cases may be complicated by some form of retinal detachment, which may be tractional or a Coats-like exudative detachment.

Purpose: Acute annular outer retinopathy (AAOR) is an uncommon disease. We present 2 illustrative cases and demonstrate disease evolution using multimodal imaging. The 18 previously reported cases in the peer-reviewed English literature are also reviewed. Methods: We conducted a case series and literature review. Results: We observed complete structural resolution by spectral-domain optical coherence tomography (SD-OCT) and ultra-widefield fundus autofluorescence in 1 case. In the literature review, 20 cases of AAOR were identified, including the 2 we have presented. Fifteen cases were unilateral and 5 bilateral, resulting in a total of 25 eyes with AAOR. Presenting symptoms included visual field defects (72%), decreased vision (48%), and photopsia (36%). Sixty-eight percent had a final visual acuity better than or equal to 20/40, while a minority (14%) were 20/200 or worse. Clinically, all eyes had a peripapillary annular band of gray-white opacification of the deep retina. Conclusions: We have reviewed and summarized the 18 previously reported cases of AAOR in the English literature and have shown for the first time that AAOR may undergo complete recovery of the external limiting membrane and ellipsoid zone on SD-OCT with resolution of disease. There is still much to be understood regarding the pathogenesis of and optimal management of AAOR.

Objective : To analyse the clinical characteristics of intraocular cysticercosis and the association of neurocysticercosis with intraocular involvement in these patientsMaterials and methods: Retrospective case series of records of patients managed at a Tertiary Care Hospital in South India. Case records of patients managed at a Tertiary Care Hospital in South India over two years (October 2012 – October 2014) were reviewed and cases reported with intraocular cysticercosis were included in the study and results analyzed.Results: Five (5) patients of intraocular cysticercosis were diagnosed in a two year period at our centre, 60% being bilateral. Eight (8) eyes of five (5) patients had intraocular cysts documented by clinical examination and B mode ultrasonography (75% eyes with active cysts, 25% eyes inactive) .Visual acuity at presentation of eyes with active cysts ranged from perception of light to counting finger 4m. The 75% eyes had tractional retinal detachment at presentation. Neurocysticercosis was documented in 80% of the cases oncomputed tomography / magnetic resonance imaging . Six (6) eyes with active cysts underwent parsplanavitrectomy with cyst removal using vitreous cutter with concurrent management of tractional retinal detachment in five (5) eyes. Postoperative visual recovery was poor in eyes with associated tractional retinal detachment while good anatomical outcome was achieved in all six (6) cases.Conclusion: Intraocular cysticercosis can be associated with cysts in other areas. High number of patients with neurocysticercosis (80%) in those with intraocular cysticercosis in our study may indicate positive association between the two which needs further investigation.

Background/AimsTo investigate the presence of short-wave fluorophores within regions of age-related macular degeneration (AMD)-associated macular atrophy (MA) area.MethodsThis is a prospective, observational, cross-sectional case series. 25 eyes (18 patients) with late AMD and clinically identified MA were enrolled. Eyes were imaged using a confocal light-emitting diode blue-light fundus autofluorescence (FAF) device (EIDON, CenterVue, Padua, Italy) with 450 nm excitation wavelength and the capability for ‘colour’ FAF imaging, including both the individual red and green components of the emission spectrum. To produce images with a high contrast for isolating the green component, the red component was subtracted from the total FAF image. The main outcome measure was the presence of green emission fluorescence component (GEFC) within the MA area. Volume spectral domain optical coherence tomography (SD-OCT) scans were obtained through the macula and the OCT was correlated with the MA lesions identified on the FAF images, including regions of increased GEFC.ResultsOf the investigated eyes, 11 out of 25 (44.0 %) showed the absence of GEFC in the MA area, whereas 14 eyes (56.0%) were characterised by GEFC within the MA area. The presence and distribution of GEFC in the MA area correlated with the presence of hyper-reflective material over Bruch’s membrane on the corresponding SD-OCT scans.ConclusionShort-wave fluorophores, which contribute to the GEFC, are present in the MA area and appear to correspond to residual debris or drusenoid material. Short-wavelength fluorophores revealed by colour FAF imaging may warrant further study.

Purpose: To describe the findings of four patients (four eyes) with optic disc melanocytoma (ODM), using multimodal imaging. Methods: Retrospective case series. Results: On ocular ultrasonography ODMs appeared as hyperechogenic lesions with moderate-to-high internal reflectivity. On blue-light fundus autofluorescence, ODMs showed total hypoautofluorescence, while, on infrared reflectance images appeared as bright and well-marginated lesions. MultiColor composite images showed reddish-brown lesions with well-defined margins. Swept-source optical coherence tomography revealed elevated lesions covering the optic disc with an irregular hyperreflective surface, dishomogeneous internal structure with hyperreflective dots, and posterior shadowing. In all cases optical coherence tomography angiography detected intratumoral blood vessels which were not detectable with fluorescein angiography. Conclusion: Multimodal imaging in ODM might be useful both at presentation, increasing the diagnostic accuracy, and at follow-up, providing helpful details, that can help to rule out the possibility of malignant transformation and other ocular complications.

ObjectiveRetinitis pigmentosa-related retinal detachment (RPRD) is rare, and the full spectrum of retinal complications is not well defined. To describe the types of retinal detachment in patients with retinitis pigmentosa and the surgical outcomes of RPRD.MethodsThis is a non-comparative, retrospective case series. An electronic database search was performed using Moorfields OpenEyes electronic health records. We identified 90 patients with RPRD between January 2000 and August 2017. Main outcome and measures are visual acuity (VA), surgical outcomes and classification of RPRD.ResultsOf the 90 patients/detachments, 61 (67.8%) were rhegmatogenous retinal detachment (RRD), 19 (21.1%) were exudative, 3 (3.3%) were tractional retinal detachment (TRD) and 7 (7.8%) had combined. 37.5% (9/24) of patients with exudative retinal detachment were treated with either cryotherapy or laser, and one patient underwent vitrectomy for vitreous haemorrhage. 56/90 patients underwent surgical intervention. Nine patients presented late and were deemed inoperable (two exudative and seven RRD). Of the RRD patients with full operative record, the primary attachment rate was 76.2% (16/21) and final reattachment rate was 85.7% (18/21) over a mean 15.4-year follow-up period. Mean VA for RRD surgery improved from 6/190 (1.51 logMAR) to 6/120 (1.31 logMAR) (p=0.194). In the TRD group, the mean VA was 6/300 (1.66 logMAR) at baseline and improved after surgery to 6/48 (0.90 logMAR) (p=0.421).ConclusionsWe demonstrated a final reattachment rate of 85.7% with a trend toward better vision following intervention for patients with RPRD. However, the final long-term vision may be poor due to the natural progression of retinitis pigmentosa-associated macular degeneration.

Purpose. To investigate the fundus autofluorescence (FAF) spectrum of punctate inner choroidopathy (PIC).Methods. This is a retrospective observational case series of 27 consecutive patients with PIC admitted from October 2013 to March 2015, who underwent short-wavelength- (SW-) and near-infrared- (NIR-) FAF imaging, spectral domain optical coherence tomography (SD-OCT), fluorescein angiography (FA), and indocyanine green angiography (ICGA).Results. There were three primary findings on the FAF imaging of patients with PIC. First, active PIC lesions revealed hypoautofluorescent spots with hyperautofluorescent margin. After the lesions regressed, the hyperautoflurescent margin faded. Second, subclinical and most of the atrophic PIC lesions appeared to be hypoautofluorescent spots. But subclinical PIC lesions were more distinctive on NIR-FAF imaging than on SW-FAF imaging. Third, hypoautofluorescent spots of PIC lesions coexisted with hyperautofluorescent patches on SW-FAF imaging. These hyperautofluorescent patches were demonstrated to be multiple evanescent white dot syndrome (MEWDS) or acute zonal occult outer retinopathy (AZOOR) lesions by subsequent multimodal imaging and faded during follow-up examinations.Conclusion. FAF imaging helps in noninvasively tracking the evolution of PIC lesions and identifying the combined MEWDS or AZOOR lesions, complementary to SD-OCT and angiographic studies.
