Abstract
BACKGROUND Macular edema (ME) results from hyperpermeability of retinal vessels, leading to chronic extravasation of plasma components into the retina and hence potentially severe visual acuity loss. Current standard of care consists in using intravitreal injections (IVI), which results in a significant medical and economic burden. During diabetic retinopathy (DR) or retinal vein occlusion (RVO), it has recently been shown that focal vascular anomalies (capillary macro-aneurysms, also termed TelCaps) for telangiectatic capillaries may play a central role in the onset, early recurrence, and/or persistence of ME. Since targeted photocoagulation of TelCaps may improve vision, identification, and photocoagulation of TelCaps, it may represent a way to improve management of ME. OBJECTIVE The Targeted Laser in (Diabetic) Macular Edema (TalaDME) study aims to evaluate whether ICG-guided targeted laser (IGTL), in association with standard of care by IVI, allows reducing the number of injections during the first year of treatment compared with IVI only, while remaining non-inferior for visual acuity. METHODS TalaDME is a French, multicentric, two-arms, randomized, sham laser-controlled, double-masked trial evaluating the effect of photocoagulation of TelCaps combined to IVI in patients with ME associated with TelCaps. Patients with vision loss related to center involved ME secondary to RVO or DR and presenting TelCaps are eligible. Two hundred and seventy eyes of 270 patients are randomized in a 1:1 ratio to standard care, i.e., IVI of anti-VEGF solely (control group) or combined with IGTL therapy (experimental group). Stratification is done on the cause of ME (i.e., RVO versus diabetes). Anti-VEGF IVI are administered to both groups monthly for 3 months (loading dose) and then with a pro re nata regimen with a monthly follow-up for 12 months. The primary endpoint will be the number of IVI and the change in visual acuity from baseline to 12 months. Secondary endpoints will be the changes in central macular thickness, impact on quality of life, cost of treatment, and incremental cost-utility ratio in each groups. KEY SAFETY Rare but severe AE linked to the use of IVI and laser, and previously described, are expected. In the sham group, rescue laser photocoagulation may be administered by the unmasked investigator if deemed necessary at month 3. DISCUSSION The best management of ME associated with TelCaps is debated, and there have been no randomized study designed to answer this question. Given the fact that TelCaps may affect 30 to 60% of patients with chronic ME due to DR or RVO, a large number of patients could benefit from a specific management of TelCaps. TalaDME aims to establish the clinical and medico-economic benefits of additional targeted laser. The results of TalaDME may raise new recommendations for managing ME and impact healthcare costs.

Abstract
PURPOSE To describe imaging characteristics of severe macular complications occurring in glaucoma and discuss available treatments. METHODS Retrospective case series of glaucomatous patients with macular retinoschisis (MR) and/or serous retinal detachment (SRD). Patients underwent a complete ophthalmological examination and multimodal imaging including retinography, SD-OCT, fluorescein and indocyanine green angiography (FA & ICGA) and adaptive optics (AO). RESULTS Ten eyes (8 patients) were included. Initial BCVA was 1.04 ± 1.12 logMAR and IOP was 24.0 ± 9.3mmHg. All eyes presented with MR while SRD was present in 5 eyes (5 patients), with a central macular thickness of 573 ± 152 μm. FA and ICGA allowed to exclude leakage in all cases. A focal lamina cribrosa defect (LCD) was found in four eyes (4 patients) using OCT, with AO providing en-face visualization of the defect in one eye. Outer retinal hole was present in 3 eyes (3 patients). No visual improvement or resolution of the macular retinoschisis was observed in eyes with medical or surgical IOP control (N = 9). Vitrectomy with internal membrane limiting peeling and gas tamponade was performed in one eye with good visual results. CONCLUSIONS Multimodal high-resolution imaging is essential to diagnose severe macular complications associated with advanced glaucoma.

Abstract
AIM While diabetic retinopathy is the most specific complication of chronic hyperglycaemia, numerous other ocular conditions also can involve the eyes of people with diabetes. Cataract, glaucoma, age-related macular degeneration, retinal vascular occlusion, and acute ischaemic optic neuropathy combine to impair vision in people with diabetes, especially when they are old. This report provides a critical analysis and an overview of the current knowledge of the main ocular disorders (excluding diabetic retinopathy) and their association in patients with diabetes. METHODS A literature search strategy was conducted for all English-language literature with a systematic review of key references until 2021. RESULTS Patients with diabetes have a high-to-moderate increased risk for most of the usual ocular disorders we reviewed with the exception of age-related macular degeneration. Exposure to chronic hyperglycaemia promotes the development of many eye disorders while acute glucose changes are involved in refractive disorders, diabetic papillopathy and acute cataract. CONCLUSION Diabetes, beyond diabetic retinopathy, increases the risk of numerous eye disorders leading to low vision with implications for daily diabetes management. Even in the absence of clearly demonstrated benefit from glucose control in all eye conditions, achieving good glycaemic control and adherence to diabetes treatment will likely help avoid an additional risk of visual impairment in people with diabetes. In perspective, interesting findings suggesting a preventive effect of metformin use on age-related macular degeneration occurrence justify further studies.

Abstract
The purpose of this study was to investigate the effect of high molecular weight hyaluronan (HMWHA) eye drops on subbasal corneal nerves in patients suffering from severe dry eye disease (DED) and to evaluate the damage of subbasal corneal nerves associated with severe DED. Designed as an international, multicenter study, 16 patients with symptoms of at least an Ocular Surface Disease Index (OSDI) score of 33, and corneal fluorescein staining (CFS) of at least Oxford grade 3, were included and randomized into two study arms. The control group continued to use their individual optimum artificial tears over the study period of eight weeks; in the verum group, the artificial tears were substituted by eye drops containing 0.15% HMWHA. At the baseline visit, and after eight weeks, the subbasal nerve plexus of 16 patients were assessed by confocal laser scanning microscopy (CSLM). The images were submitted to a masked reading center for evaluation. Results showed a significant increase of total nerve fiber lengths (CNFL) in the HMWHA group (p = 0.030) when compared to the control group, where the total subbasal CNFL did not significantly change from baseline to week 8. We concluded that in severe DED patients, HMWHA from topically applied eye drops could cross the epithelial barrier and reach the subbasal nerve plexus, where it exercised a trophic effect.

Abstract
AIMS Recent trials provide conflicting results on the association between glucagon-like peptide 1 receptor agonists (GLP-1RA) and diabetic retinopathy (DR). The aim of the AngioSafe type 2 diabetes (T2D) study was to determine the role of GLP-1RA in angiogenesis using clinical and preclinical models. METHODS We performed two studies in humans. In study 1, we investigated the effect of GLP-1RA exposure from T2D diagnosis on the severity of DR, as diagnosed with retinal imaging (fundus photography). In study 2, a randomized 4-week trial, we assessed the effect of liraglutide on circulating hematopoietic progenitor cells (HPCs), and angio-miRNAs.We then studied the experimental effect of Exendin-4, on key steps of angiogenesis: in vitro on human endothelial cell proliferation, survival and three-dimensional vascular morphogenesis; and in vivo on ischemia-induced neovascularization of the retina in mice. RESULTS In the cohort of 3154 T2D patients, 10% displayed severe DR. In multivariate analysis, sex, disease duration, glycated hemoglobin (HbA1c), micro- and macroangiopathy, insulin therapy and hypertension remained strongly associated with severe DR, while no association was found with GLP-1RA exposure (o 1.139 [0.800-1.622], P = .47). We further showed no effect of liraglutide on HPCs, and angio-miRNAs. In vitro, we demonstrated that exendin-4 had no effect on proliferation and survival of human endothelial cells, no effect on total length and number of capillaries. Finally, in vivo, we showed that exendin-4 did not exert any negative effect on retinal neovascularization. CONCLUSIONS The AngioSafe T2D studies provide experimental and clinical data confirming no effect of GLP-1RA on angiogenesis and no association between GLP-1 exposure and severe DR.

Abstract
PURPOSE The aim of this study was to define the role of dystrophin Dp71 in corneal angiogenesis. METHODS Inflammation-induced corneal neovascularization experiments were performed in Dp71-null mice and C57BL/6J wild-type mice. RESULTS The corneal neovascular area covered by neovascularization was larger in the injured corneas of the Dp71-null mice compared to the corneas of the wild-type mice: 40.72% versus 26.33%, respectively (p<0.005). Moreover, increased angiogenesis was associated with a high expression of vascular endothelial growth factor (VEGF). Similarly, aortic ring assays showed a significant enhancement of the neovascular area. CONCLUSIONS These results suggest that dystrophin Dp71 could play an important role as a negative regulator of corneal angiogenesis.

Abstract
Importance Capillary dropout is a hallmark of diabetic retinopathy, but its role in visual loss remains unclear. Objective To examine how macular vessel density is correlated with visual acuity (VA) in patients younger than 40 years who have type 1 diabetes without macular edema but who have diabetic retinopathy requiring panretinal photocoagulation. Design, Settings, and Participants Retrospective cohort study of VA and optical coherence tomography angiography data collected from consecutive patients during a single visit to Lariboisière Hospital, a tertiary referral center in Paris, France. The cohort included 22 eyes of 22 patients with type 1 diabetes without macular edema but with bilateral rapidly progressive diabetic retinopathy that was treated with panretinal photocoagulation between August 15, 2015, and December 30, 2016. Eyes were classified into 2 groups by VA: normal (logMAR, 0; Snellen equivalent, 20/20) and decreased (logMAR, >0; Snellen equivalent, <20/20). The control group included 12 eyes from age-matched healthy participants with normal vision. Main Outcomes and Measures Visual acuity and mean vessel density in 4 retinal vascular plexuses: the superficial vascular plexus and the deep capillary complex, which comprises the intermediate capillary plexus and the deep capillary plexus. Results Of the 22 participants, 11 (50%) were men, mean (SD) age was 30 (6) years, and mean (SD) hemoglobin A1c level was 8.9% (1.6%). Of the 22 eyes with diabetic retinopathy, 13 (59%) had normal VA and 9 (41%) had decreased VA (mean [SD]: logMAR, 0.12 [0.04]; Snellen equivalent, 20/25). Mean [SE] vessel density was lower for eyes with diabetic retinopathy and normal VA compared with the control group in the superficial vascular plexus (44.1% [0.9%] vs 49.1% [0.9%]; difference, -5.0% [1.3%]; 95% CI, -7.5% to -2.4%; P < .001), in the deep capillary complex (44.3% [1.2%] vs 50.6% [1.3%]; difference, -6.3% [1.8%]; 95% CI, -9.9% to -2.7%; P = .001), in the intermediate capillary plexus (43.8% [1.2%] vs 49.3% [1.2%]; difference, -5.5% [1.7%]; 95% CI, -9.0% to -2.0%; P = .003), and in the deep capillary plexus (24.5% [1.0%] vs 30.5% [1.0%]; difference, -6.1% [1.4%]; 95% CI, -8.9% to -3.2%; P < .001). Mean vessel density was lower in eyes with diabetic retinopathy and decreased VA compared with eyes with diabetic retinopathy and normal VA; the mean (SE) loss was more pronounced in the deep capillary complex (34.6% [1.5%] vs 44.3% [1.2%]; difference, -9.6% [1.9%]; 95% CI, -13.6% to -5.7%; P < .001), especially in the deep capillary plexus (15.2% [1.2%] vs 24.5% [1.0%]; difference, -9.3% [1.5%]; 95% CI, -12.4% to -6.1%; P < .001), than in the superficial vascular plexus (39.6% [1.1%] vs 44.1% [0.9%]; difference, -4.5% [1.4%]; 95% CI, -7.3% to -1.7%; P = .002). Conclusions and Relevance These data suggest that in patients with type 1 diabetes without macular edema but with severe nonproliferative or proliferative diabetic retinopathy, decreased VA may be associated with the degree of capillary loss in the deep capillary complex.

Abstract
Purpose: Treatment of persistent ocular discomfort in patients with Cogan's epithelial basement membrane dystrophy (EBMD) is a challenge for ophthalmologists. This study aimed to determine the efficacy of a topical heparan sulfate mimetic polymer (HSMP) in reducing ocular discomfort in EBMD patients. Methods: This retrospective, noninterventional study included 22 consecutive patients in 3 tertiary ophthalmological units with spontaneous, recurrent, acute ocular pain, resistant to various topical lubricants. After EBMD diagnosis, HSMP treatment was initiated while lubricating eye drops were continued. The main study outcome was the change in ocular discomfort assessed using the ocular surface disease index (OSDI) from initiation of treatment to last follow-up visit. Results: The mean OSDI decreased from 46.7 ± 22.3 to 31.6 ± 17.4 (P < 0.001) at first visit and 32.5 ± 17.9 (P < 0.01) at last visit. The rate of patients with severe ocular surface disease (OSDI >33) decreased from 68.2% to 36.4% at first visit and 42.9% at last visit. After a median follow-up of 8.5 months, 7 (31.8%) patients discontinued the HSMP treatment due to a marked improvement in ocular surface comfort and no recurrence of ocular pain, 5 (22.7%) due to lack of efficacy, and 1 (4.5%) due to an ocular adverse event (not treatment related). Eight patients continued treatment after the last visit and 1 patient was lost to follow-up. Globally, HSMP prevented acute painful episodes in 11 (61.1%) of 18 patients followed for ∼4 months. Conclusions: Topical HSMP may be an option for alleviating ocular discomfort in patients with EBMD resistant to standard symptomatic treatments.

Abstract
OBJECTIVE To evaluate the role of a fast track for management of patients with neovascular age- related macular degeneration (nARMD) treated by intravitreal injection of anti-VEGF. PATIENTS The records of 100 patients in the chronic maintenance phase of intravitreal anti-VEGF followed in the fast track and 63 patients followed in the standard protocol for at least 12 months were retrospectively analyzed. METHOD Patients in the fast track underwent visual acuity (VA) testing by ETDRS, optical coherence tomography (OCT) and a physician assessment. The injection was performed the same day whenever possible. The primary endpoint to evaluate patient adherence was the time between the ideal date of visit or injection prescribed by the physician and the actual date of administration. RESULTS The mean time between the ideal date of visit or injection prescribed by the physician and the actual date of administration was 4.1±7.5 days for the patients followed in the fast track and 5.6±18.7 days for the patients followed in the standard protocol. Mean VA remained stable for the patients followed in the fast track: 20/50 (20/800 to 20/20) at baseline vs. 20/50 (20/800 to 20/16) at the conclusion of follow-up. It dropped from 40/50 at baseline to 20/63 at the conclusion of follow-up for the patients followed in the standard protocol. CONCLUSION In the context of a fast track, it was possible to improve the adherence of nARMD patients and maintain their VA gain or stabilization achieved after the induction phase.

Abstract
BACKGROUND AND OBJECTIVE To analyze cone mosaic metrics on adaptive optics (AO) images as a function of retinal eccentricity in two different age groups using a commercial flood illumination AO device. PATIENTS AND METHODS Fifty-three eyes of 28 healthy subjects divided into two age groups were imaged using an AO flood-illumination camera (rtx1; Imagine Eyes, Orsay, France). A 16° × 4° field was obtained horizontally. Cone-packing metrics were determined in five neighboring 50 µm × 50 µm regions. Both retinal (cones/mm2 and µm) and visual (cones/degrees2 and arcmin) units were computed. RESULTS Results for cone mosaic metrics at 2°, 2.5°, 3°, 4°, and 5° eccentricity were compatible with previous AO scanning laser ophthalmoscopy and histology data. No significant difference was observed between the two age groups. CONCLUSIONS The rtx1 camera enabled reproducible measurements of cone-packing metrics across the extrafoveal retina. These findings may contribute to the development of normative data and act as a reference for future research. [Ophthalmic Surg Lasers Imaging Retina. 2017;48:45-50.].

Abstract
Purpose: To demonstrate the involvement of the various renal structures in acute tubular necrosis (ATN). Material and Methods: In 15 rats, using a T1-/T2-weighted sequence, either gadodiamide alone, or gadodiamide in combination with sprodiamide (a susceptibility agent) were used to enhance the various anatomical substrates of the kidney. The results were compared to those of pathological verification. Results: Experimentally induced ATN of the rat kidney causes profound changes in the medulla, leaving the cortex largely intact. The difference between the normal cortex and the partially necrotic outer medulla, on the one hand, and the papillary region, was significantly enhanced with the combination, whereas a larger region composed of the inner and outer medulla was enhanced after the gadolinium chelate alone. Conclusion: The results varied considerably between the two procedures; the double contrast demonstrated a clear difference between the inner and outer medulla, and the gadolinium chelate alone demonstrated a clear difference between the medulla and the cortex. These results demonstrated a clear difference in the compartmentalization between the inner and outer medullary regions, providing complementary information about the pathological condition of the kidney.

Abstract
PURPOSE To study the symmetry in response to bilateral diabetic macular oedema (DME) treated with bilateral intravitreal injections of ranibizumab (IVR). METHODS The charts of 36 eyes of 18 patients treated with a loading dose of three monthly IVR in both eyes were retrospectively reviewed. Favourable anatomical response was defined as a decrease by more than 10% in baseline central macular thickness (CMT), and favourable functional response was defined as an increase in visual acuity (VA) ≥5 letters. A symmetric response was defined as a similar anatomical and/or functional response in the first (FE) and second (SE) treated eyes. RESULTS The VA improved significantly after ranibizumab treatment in both eyes (p < 0.01). A statistically significant positive correlation was found for the functional response to ranibizumab between the FE and the SE (R(2) = 0.26, p = 0.03). The mean CMT decreased significantly in both eyes (p < 0.01). A strong positive correlation was observed between the anatomical response to ranibizumab in the FE and the SE (R(2) = 0.37, p = 0.01). Symmetric favourable anatomical and functional responses were observed in 13 patients (72%). In two additional patients, an asymmetric functional response was observed despite a decrease in retinal thickness in both eyes. CONCLUSION Symmetric anatomical and functional responses were observed in 72% of patients with DME after three initial IVR in each eye. This finding could be of clinical interest in the decision to treat the fellow eye, in a disease where a bilateral involvement is frequent.

Abstract
Purpose To evaluate the efficacy and safety of sustained-delivery fluocinolone acetonide (FAc) intravitreal implant for diabetic macular edema (DME). Patients and methods Prospective study in patients with DME insufficiently responsive to laser and anti-vascular endothelial growth factor (anti-VEGF). Patients with history of rise of intraocular pressure after intravitreal corticosteroids were excluded. Results The macular edema rapidly decreased both in group 1 (prior laser only; n=7 eyes) and group 2 (prior laser and ≥3 monthly anti-VEGF therapy; n=10 eyes) and central subfield thickness was reduced by −299 μm (P=0.008) and −251 μm (P=0.016) at 12 months, respectively. Mean area under the curve from baseline to last value for pseudophakic eyes was +4.2 letters in group 1 and +9.5 letters in group 2. Overall, the FAc implant was well tolerated. Conclusion This prospective study confirms the efficacy of the FAc implant in DME patients insufficiently responsive to laser and anti-VEGF. Moreover, with a careful patient selection, our safety results would support an earlier use of FAc in the DME treatment pathway.

Abstract
PURPOSE To assess the thickness of the ganglion cell-inner plexiform layer (GCIPL) in eyes with resolved diabetic macular edema (DME), using spectral-domain optical coherence tomography (SD-OCT), and its relationship with the visual function. METHODS This retrospective observational case-control cohort study included eyes of diabetic patients with resolved DME (r-DME eyes), that is, normal central macular thickness (CMT) after treatment of DME, and eyes of aged-matched diabetic patients without maculopathy (no-DME eyes). The GCIPL thickness was measured on a macular cube SD-OCT scan using a specific automatic segmentation algorithm. Linear regression analyses were performed to determine the association between the GCIPL thickness and the visual acuity (VA) measured at the time of the OCT measurement. RESULTS Average GCIPL thickness was reduced in r-DME eyes compared with no-DME eyes (74 ± 14 μm versus 83.2 ± 6 μm, P = 0.0189), whereas no significant difference in mean CMT was observed (260.0 ± 34 μm versus 265.7 ± 22 μm, P = 0.847). Visual acuity significantly correlated with the average GCIPL thickness (r = 0.8, P < 0.0001) and minimum GCIPL thickness (r = 0.84, P < 0.0001) in r-DME eyes. CONCLUSIONS Despite favorable anatomic response and restoration of a CMT in the range of normal values after resolution of DME, the GCIPL thickness in r-DME eyes was lower than that in no-DME eyes and correlated with the VA. These results suggest that inner retinal alterations occurring in patients with DME and diabetic retinopathy may lead to visual deficiency persisting after treatment.

Abstract
PURPOSE To analyze optical coherence tomography angiography images of retinal capillary perfusion in incomplete central retinal artery occlusion. METHODS Case report of a 63-year-old male white patient with transient vision loss in the left eye related to central retinal artery occlusion, secondary to left internal carotid thrombosis. Optical coherence tomography angiography images were captured with Angiovue (Optovue, Inc., Freemont, CA). Retinal capillary bed was segmented into the superficial and deep capillary plexus. Each blood flow angiography image was associated with an en face optical coherence tomography image and an optical coherence tomography B-scan showing the level of segmentation. RESULTS In the left eye, visual acuity was 20/20 five days after transient vision loss. Optical coherence tomography angiography showed a normal superficial capillary plexus but the deep capillary plexus was not distinguishable compared with the right eye, although the posterior pole appeared well perfused on fluorescein angiography. Retrobulbar Doppler ultrasound confirmed a reduced blood flow velocity in the left central retinal artery. CONCLUSION In this case of incomplete and transient central retinal artery occlusion, the deep capillary plexus was poorly visible on optical coherence tomography angiography, which could be due to its elective hypoperfusion and explain the ischemic whitening of the inner nuclear layer, previously described as paramacular acute middle maculopathy. However, the reason why the deep capillary plexus is more sensitive to reduced blood flow in the central retinal artery is not fully understood. In a case of partial central retinal artery occlusion, optical coherence tomography angiography allowed showing elective poor perfusion of the retinal deep capillary plexus.

Abstract
PURPOSE To explore the anatomic correlation of the retinal cone mosaic on adaptive optics images. DESIGN Retrospective nonconsecutive observational case series. METHODS A retrospective review of the multimodal imaging charts of 6 patients with focal alteration of the cone mosaic on adaptive optics was performed. Retinal diseases included acute posterior multifocal placoid pigment epitheliopathy (n = 1), hydroxychloroquine retinopathy (n = 1), and macular telangiectasia type 2 (n = 4). High-resolution retinal images were obtained using a flood-illumination adaptive optics camera. Images were recorded using standard imaging modalities: color and red-free fundus camera photography; infrared reflectance scanning laser ophthalmoscopy, fluorescein angiography, indocyanine green angiography, and spectral-domain optical coherence tomography (OCT) images. RESULTS On OCT, in the marginal zone of the lesions, a disappearance of the interdigitation zone was observed, while the ellipsoid zone was preserved. Image recording demonstrated that such attenuation of the interdigitation zone co-localized with the disappearance of the cone mosaic on adaptive optics images. In 1 case, the restoration of the interdigitation zone paralleled that of the cone mosaic after a 2-month follow-up. CONCLUSION Our results suggest that the interdigitation zone could contribute substantially to the reflectance of the cone photoreceptor mosaic. The absence of cones on adaptive optics images does not necessarily mean photoreceptor cell death.

Abstract
PURPOSE To study spontaneous variations of central macular thickness (CMT) and its relation to blood pressure (BP) in patients with diabetic macular oedema (DME). METHODS 23 diabetic patients presenting with DME with a CMT ≥ 260 μm on optical coherence tomography (OCT-3, Carl Zeiss Meditec, CA) were followed every 2 weeks for 3 months. At baseline, ambulatory 24H-BP monitoring (ABPM) was performed, as well as five CMT measurements (9 am, 12 am, 3 pm, 6 pm and 9 am the day after). During follow-up, BP and CMT were simultaneously measured at 9 am. RESULTS Significant spontaneous variations in CMT (at least one change in CMT greater than 11% compared to the median CMT value) were observed over 3 months in 48% of patients. Mean CMT decreased over the day and increased during the night, but not significantly (p = 0.1). During the 6 visits, the CMT at 9 am positively correlated with the pulse pressure (PP) measured at the same time (r = 0.29, p = 0.0008). In addition, the mean 24H-CMT was positively correlated with the mean 24H- PP (r = 0.48, p = 0.02). CONCLUSION Significant spontaneous changes in CMT of patients with DME were observed in nearly half of cases over 3 months. Retinal thickness was correlated to PP levels (patients with higher CMT had higher PP levels). This high variability of macular oedema, and the influence of BP on retinal thickness, should be taken into consideration by practitioners when evaluating the benefit of a therapy in DME.

Abstract
The prognosis for pancreatic cancer is poor, and early diagnosis is essential for surgical management. By comparison with its classic form, the presence of acute or chronic inflammatory signs will hinder its detection and delay its diagnosis. The atypical forms of acute pancreatitis need to be known in order to detect patients who require additional morphological investigations to search for an underlying tumour. In contrast, pseudotumoral forms of inflammation (chronic pancreatitis, cystic dystrophy in heterotopic pancreas, autoimmune pancreatitis) may simulate a cancer, and make up 5-10% of the surgical procedures for suspected cancer. Faced with these pseudotumoral masses, interpretation relies on various differentiating signs and advances in imaging.

Abstract
AIM Spontaneous diurnal variations measured by optical coherence tomography (OCT) have been reported in diabetic macular oedema (DME) together with a daytime decrease in central macular thickness (CMT). For this reason, this study aimed to investigate the influence of acute glucose and blood pressure changes on daytime variations in CMT in patients with DME. METHODS In this prospective observational study of type 1 (n=4) and type 2 (n=18) diabetic patients with DME, OCT scans, capillary blood glucose, and systolic and diastolic blood pressure measurements were performed at 9 a.m., 12 a.m., 3 p.m., 6 p.m. and again at 9 a.m. the day after. At the same time, the study protocol included simultaneous ambulatory blood pressure and glucose monitoring over a 24-h period. Hypoglycaemic episodes, defined as glucose values<60mg/dL, were also recorded. RESULTS CMT decreased consistently between 9 a.m. and 6 p.m. in 10 patients (from 374±82μm to 337±72μm; P=0.01) and increased or remained steady in 12 others (from 383±136μm to 390±149μm; P=0.58), with a significant difference in CMT absolute change between the two groups (P<0.001). In the study population as a whole, the lower the mean diurnal blood glucose, the smaller the decrease in CMT during the day (P=0.027). Also, eight (67%) of the 12 patients with a flat CMT profile experienced a diurnal hypoglycaemic event whereas none of those with a CMT decrease had hypoglycaemia (P=0.002). CONCLUSION Hypoglycaemic events may explain the lack of diurnal CMT decrease in diabetic patients with DME. However, further studies need to be conducted to evaluate whether having no diurnal CMT decrease is associated with a poorer visual prognosis and whether it can be modified by better glucose control.

Abstract
Lymphoma staging systematically includes a CT scan of the cervical, thoracic and abdominopelvic regions. PET is indicated in diffuse large B cell lymphomas (DLBCL) and Hodgkin's disease. Evaluation of the response to treatment is based on Cheson's 1999 morphological criteria, which have been replaced by the 2007 IWC criteria, which combine morphological and metabolic responses. CT and FDG-PET are complementary in characterizing residual masses: if negative, a PET scan indicates the absence of residual disease, if positive; it directs a CT-guided biopsy to obtain the histological evidence. Monitoring clinical features and laboratory values is primordial following treatment. Imaging is performed as a second intention for investigating a relapse, if necessary associated with a PET scan. Multimodal imaging implies multidisciplinary consultation between haematologists, imaging specialists and histopathologists.

Abstract
Positron emission tomography (PET) has a proven role in the assessment diffuse large B-cell lymphoma (DLBCL) and Hodgkin's lymphoma (HL). The clinical impact of PET carried out at the end of the patient's course of treatment is undeniable and recommendations must be followed in the interpretation of these examinations. PET is highly recommended as part of the initial investigations of these diseases because it can be used as a reference for the interpretation at treatment completion and allows disease spread to be assessed with greater sensitivity and specificity than when computed tomography (CT) is used. It seems to be certain that PET is useful for interim examinations too, in terms of assessing prognosis in DLBCL and HL, although its impact in terms of early changes to treatment is still to be determined. The criteria for interpreting the results of these early assessments are still evolving and the annual meetings in Menton, France, of groups of experts are leading towards a uniform interpretation method. In other types of lymphoma, PET can be useful for confirming local disease staging, especially in follicular lymphoma, and for guiding biopsy in patients with low-grade lymphoma that is suspicious for transformation into more aggressive disease. Several studies are in agreement that PET is valuable for assessing prognosis at treatment completion in FL and mantle cell lymphoma, but prospective studies are needed for this new indication to be validated.

Abstract
Multiple myeloma (MM) is a malignant haematological disease characterised by clonal proliferation of malignant plasma cells in the bone marrow. MM is expressed by diffuse infiltration of the bone marrow, focal bone lesions and extra-medullary lesions. Conventional staging follows the Salmon and Durie classification, which was recently revised (Salmon and Durie plus) to include MRI and FDG-PET examinations. FDG-PET is being evaluated for initial staging and therapeutic monitoring and its place still needs to be validated, particularly in comparison with MRI of the pelvis and spine, the reference examination for diagnosis, which is systematically combined with X-rays of the skeleton. Certain recent data in the literature suggest that FDG-PET provides better staging of the disease at the time of diagnosis than MRI, and that the examination has considerable prognostic value when it normalises after the initial courses of chemotherapy and at the end of treatment. As for the evaluation of lymphomas, the interpretation criteria should be standardised.

DESIGN A panel of experts (appointed by the Italian Association of Clinical Endocrinologists (AME)) appraised the methodological quality of the relevant studies, summarized their results, and discussed the evidence reports to find consensus. RADIOLOGICAL ASSESSMENT Unenhanced computed tomography (CT) is recommended as the initial test with the use of an attenuation value of ≤10 Hounsfield units (HU) to differentiate between adenomas and non-adenomas. For tumors with a higher baseline attenuation value, we suggest considering delayed contrast-enhanced CT studies. Positron emission tomography (PET) or PET/CT should be considered when CT is inconclusive, whereas fine needle aspiration biopsy may be used only in selected cases suspicious of metastases (after biochemical exclusion of pheochromocytoma). HORMONAL ASSESSMENT: Pheochromocytoma and excessive overt cortisol should be ruled out in all patients, whereas primary aldosteronism has to be considered in hypertensive and/or hypokalemic patients. The 1 mg overnight dexamethasone suppression test is the test recommended for screening of subclinical Cushing's syndrome (SCS) with a threshold at 138 nmol/l for considering this condition. A value of 50 nmol/l virtually excludes SCS with an area of uncertainty between 50 and 138 nmol/l. MANAGEMENT Surgery is recommended for masses with suspicious radiological aspects and masses causing overt catecholamine or steroid excess. Data are insufficient to make firm recommendations for or against surgery in patients with SCS. However, adrenalectomy may be considered when an adequate medical therapy does not reach the treatment goals of associated diseases potentially linked to hypercortisolism.

Abstract
We describe a novel approach for screening retinal imagery to detect evidence of abnormalities. In this paper, we focus our efforts on age-related macular degeneration (AMD), a pathology that may often go undetected in the early or intermediate stages, and can lead to a neovascular form often resulting in blindness, if untreated. Our strategy for retinal anomaly detection is to employ a single class classifier applied to fundus imagery. We use a multiresolution locally-adaptive scheme that identifies both normal and anomalous regions within the retina. We do this by using a hybrid parametric/non-parametric characterization of the support of the probability distribution of normal retinal tissue in color and intensity feature space. We apply this approach to screen for evidence of AMD on a dataset of 66 healthy and pathological cases and found a detection sensitivity and specificity of 95% and 96%.

Abstract
PURPOSE To compare fluorescein leakage from choroidal neovascularization (CNV) with signs of intraretinal or subretinal fluid on time-domain optical coherence tomography (TD-OCT) and spectral-domain optical coherence tomography (SD-OCT) in patients receiving anti-vascular endothelial growth factor (anti-VEGF) therapy for CNV caused by age-related macular degeneration (AMD). DESIGN Retrospective, consecutive case series. PARTICIPANTS Fifty-nine eyes of 56 patients with neovascular AMD receiving anti-VEGF therapy. METHODS All patients were imaged with fluorescein angiography (FA), TD-OCT (Stratus, Carl Zeiss Meditec, Inc., Dublin, CA), and SD-OCT (Cirrus, Carl Zeiss Meditec, Inc). All images were analyzed by an experienced reading center grader masked to all clinical data. Fluorescein leakage from CNV and OCT abnormalities (presence of interstitial fluid, retinal cystoid abnormalities, and subretinal fluid) were documented for each visit. MAIN OUTCOME MEASURES Agreement of OCT findings with presence or absence of fluorescein leakage from CNV. RESULTS For TD-OCT, the sensitivity, specificity, positive predictive value, and negative predicative value (and 95% confidence intervals) for OCT abnormalities were 59% (46-72), 63% (50-75%), 61% (49-73), and 61% (48-74), respectively. For SD-OCT, the sensitivity, specificity, positive predictive value, and negative predictive value (and 95% confidence intervals) for OCT abnormalities were 90% (82-98), 47% (34-60), 62% (49-75), and 82% (72-92), respectively. CONCLUSIONS Spectral-domain optical coherence tomography seems more likely than TD-OCT to detect abnormalities when fluorescein leakage from CNV is detected after anti-VEGF therapy. However, SD-OCT also seems to detect abnormalities frequently in the absence of fluorescein leakage from CNV. Whether treatment decisions based on any of these modalities result in visual acuity outcomes that are similar or superior to monthly treatments without such evaluations is unknown, but this study provides information that may assist in the design of studies to evaluate the role of OCT and FA in the management of CNV.

Abstract
PURPOSE Heidelberg retina tomograph II (HRTII) examination was performed with cornea module in one patient with Acanthamoeba keratitis (AK) to provide images detailing characteristic findings of the disease. METHODS A 34-year-old woman presented with clinical signs and symptoms of AK. HRTII with cornea module was performed and the patient underwent laboratory investigations. RESULTS HRTII examination with cornea module revealed numerous 20-26-micro m diameter high-contrast round particles within the corneal epithelium and anterior stroma, resembling Acanthamoeba cysts. Stellate cells as well as ovoid irregular objects, possibly inflammatory cells, trophozoites, altered cysts, or activated keratocytes, were also present in the area of stromal infiltrates. Laboratory investigations confirmed the diagnosis of AK. CONCLUSIONS HRTII cornea module can be helpful in the diagnosis of AK by identifying acanthamoeba cyst-like structures in the cornea. This technique also has potential uses in monitoring the efficiency of anti-infective treatment.

Abstract
BACKGROUND AND PURPOSE Lack of cerebral circulation is an important confirmatory test for brain death (BD). Conventional angiography remains the standard imaging method, but CT angiography (CTA) is emerging as an alternative. France accepts BD diagnoses relying on a score based on lack of opacification of 7 intracerebral vessels in CTA images. The purpose of this study was to validate the efficiency of this score and to evaluate the sensitivity of a novel 4-point CTA score in confirming BD. MATERIALS AND METHODS A prospective multicentric study was conducted during 12 months with 105 patients referred for CTA to confirm a clinical diagnosis of BD. Clinical data were recorded. CTA images were interpreted first by local radiologists at the referent center, resulting in a 7-point score based on lack of opacification of the pericallosal and cortical segments of the middle cerebral arteries (MCAs), internal cerebral veins (ICVs), and 1 great cerebral vein per patient and, second, by a consensus panel of 3 expert radiologists, blinded to the initial scores, resulting in novel 4-point scores based on the lack of opacification of the cortical segments of the MCAs and ICVs. RESULTS Injection of contrast medium did not alter renal function. With the initial 7-point score, sensitivity was 62.8%. With the simplified 4-point score, sensitivity was 85.7% and specificity was 100%. Opacification of ICVs was absent in 98.1% of patients. CONCLUSIONS Lack of opacification in the cortical segments of the MCAs and internal veins in CTA is efficient and reliable for confirming BD.
