Combined central serous chorioretinopathy, hypermetropia, short axial length, chorioretinal folds, enlarged/thickened ocular coats, with varying association of scleral changes (CHAFES).

PURPOSE: To describe a condition with the following features: chronic central serous chorioretinopathy (CCSC), chorioretinal folds, scleral changes (including any of the following flattened or 'squared off' posterior pole, 'T sign', or thickened ocular coats), accompanied by a short axial length and hypermetropia in a series of 7 patients. METHODS: The case notes of 7 patients presenting with a combination of CSC, choroidal folds scleral changes and hypermetropia were reviewed as part of a retrospective case series. Corrected visual acuities, serial refraction, colour imaging, fluorescein and indocyanine green angiography findings, together with B-ultrasound scan features were recorded, with axial length measurements as available (< 23.3 mm was defined as short). RESULTS: The study included 14 eyes of 7 subjects (2 females and 5 males) with a primary presentation of central vision disturbance. All patients showed signs of previous or current episodes of the following features in at least one eye: CSC (5/7 bilateral); choroidal folds (6/7 bilateral), thickening of ocular coats in the 5 in whom this was measured, at least one scleral abnormality on ultrasound in at least one eye. A short axial length at final appointment was recorded in 13/14 eyes. CONCLUSIONS AND RELEVANCE: The combination of CCSC with choroidal folds, hypermetropia with apparent shortening of the eyeball associated with one or more scleral abnormalities such as a flattened or 'squared off 'appearance of the B ultrasound may be a specific ocular condition. The aetiology of this particular combination of posterior segment manifestations is unknown; the choroid could be the primary focus of disease with secondary involvement of the sclera. Alternatively, the features observed may result from a chronic inflammatory process affecting the sclera with secondary effects on the choroid, retinal pigment epithelium and retina. In our case series, the final vision was not significantly different from vision at presentation.

Point-of-Care Ultrasound in the Evaluation of the Acutely Painful Red Eye.

BACKGROUND: Visual loss, ocular pain, and red eye are common presentations to front-line physicians in the emergency department, urgent care centers, or the primary care office. In recent decades, point-of-care ultrasound (POCUS) has been used by clinicians at the bedside in the evaluation and management of a vast array of patients, including those with ocular complaints. CASE REPORT: A 33-year-old man presented to the emergency department with left eye pain for 4 weeks' duration. The physical examination revealed visual acuity of 20/400 in the affected eye and diffuse conjunctival injection with perilimbal sparing and scleral edema. Using POCUS, he was noted to have diffuse thickening of the globe wall in the symptomatic eye with a thin layer of fluid posterior to the globe in Tenon's space and mild enlargement of the optic nerve sheath diameter. He was ultimately diagnosed with posterior scleritis. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Posterior scleritis carries the potential for significant visual impairment when the diagnosis is missed or delayed. POCUS findings can aid the front-line physician in making the diagnosis of posterior scleritis allowing earlier initiation of appropriate therapy and follow-up.

Prenatally diagnosed monochorionic diamniotic triplet pregnancy.

We present an extremely rare case of monochorionic diamniotic (MD) triplet pregnancy diagnosed via ultrasonography at the end of the first trimester that resulted in delivery of three healthy newborns. Ultrasonography for a 34-year-old woman at 12 weeks of gestation showed three fetuses and one placenta with a T-sign at the initial segment of the dividing membrane. Color Doppler examination revealed umbilical cord entanglement between two fetuses in one sac in addition to another sac containing one fetus. Therefore, this was diagnosed as MD triplet pregnancy. The triplets were delivered by cesarean section at 35 weeks of gestation and were healthy without neurological morbidities at the age of 28 days. Histopathological examination also revealed an MD triplet placenta. The possibility of MD triplet pregnancy should be recognized, although it is rare.

Posterior Scleritis Associated with Late-Onset Takayasu Arteritis: A Case Report.

PURPOSE: To describe a rare case of posterior scleritis associated with late-onset Takayasu arteritis. METHODS: A case report of a 75-year-old female presenting with posterior scleritis, eventually diagnosed with late-onset Takayasu arteritis was described. Several medical evaluation visits were conducted, including ophthalmological and rheumatological follow-up. Multiple diagnostic tests were carried out, and the cornerstones of the treatment were corticosteroids and the IL-6 inhibitor tocilizumab. RESULTS: The patient was admitted to our hospital's emergency room with right unilateral eyelid edema, chemosis and red eye. She had previously experienced two episodes that were misdiagnosed as preseptal cellulitis. The presence of choroidal folds and the T sign on the ultrasound exam were highly suggestive of posterior scleritis. Later, the patient was diagnosed with Takayasu arteritis, a type of large vessel vasculitis. Treatment with steroids was started, which was later switched to IL-6 inhibitors to achieve better control of the systemic disease. CONCLUSION: Posterior scleritis is often misdiagnosed, necessitating high clinical suspicion. Multimodal diagnosis is important to establish an accurate diagnosis. Up to 34% of cases may be associated with a systemic disease. This is the first case described in the literature of posterior scleritis associated with late-onset Takayasu arteritis.

B-Scan Ultrasonography Findings in Unilateral Posterior Scleritis.

Purpose: To evaluate the B-scan ultrasound findings in unilateral posterior scleritis. Methods: This was a retrospective observational case series at a tertiary uveitis clinic. The study population included patients who had been diagnosed with milder forms of unilateral posterior scleritis since 2010 and had B-scan ultrasonography of that eye. The healthy eye of each patient was considered the control eye for that patient. Results: The average age of patients was 50.2 ± 17.8 (range, 18-67). Posterior scleritis was idiopathic in 6 (66.7%) patients and associated with rheumatoid arthritis in two and HLA-B27 ankylosing spondylitis in one patient. The thickness of the thickest area in the diseased eye was 2.08 ± 0.49 (range, 1.35-3.2) and the control eye was 1.53 ± 0.38 (range, 1.03-2.3). The difference between the symptomatic and control eye was statistically significantly different (P = 0.02). 1.7 mm was the cut-off-point on the receiver operating characteristics curve with the highest combined sensitivity and specificity of 87.5% and 88.9%, respectively. Comparing the thickness of the thickest section of the symptomatic eye of one patient with the same section in the other eye of the same patient, there was a difference of 20% or more in sclero-choroidal complex. Conclusions: In this study, the sclero-choroidal complex thickness higher than 1.7 mm has the highest combined sensitivity and specificity. Comparing the thickest section of the symptomatic eye of one patient with the same section in the other eye can be diagnostic.

T-SIGn tumor reengineering therapy and CAR T cells synergize in combination therapy to clear human lung tumor xenografts and lung metastases in NSG mice.

Although chimeric antigen receptor (CAR) T cells have emerged as highly effective treatments for patients with hematologic malignancies, similar efficacy has not been achieved in the context of solid tumors. There are several reasons for this disparity including a) fewer solid tumor target antigens, b) heterogenous target expression amongst tumor cells, c) poor trafficking of CAR T cells to the solid tumor and d) an immunosuppressive tumor microenvironment (TME). Oncolytic viruses have the potential to change this paradigm by a) directly lysing tumor cells and releasing tumor neoantigens, b) stimulating the local host innate immune response to release cytokines and recruit additional innate and adaptive immune cells, c) carrying virus-encoded transgenes to "re-program" the TME to a pro-inflammatory environment and d) promoting an adaptive immune response to the neoantigens in this newly permissive TME. Here we show that the Tumor-Specific Immuno-Gene (T-SIGn) virus NG-347 which encodes IFNα, MIP1α and CD80 synergizes with anti-EGFR CAR T cells as well as anti-HER-2 CAR T cells to clear A549 human tumor xenografts and their pulmonary metastases at doses which are subtherapeutic when each is used as a sole treatment. We show that NG-347 changes the TME to a pro-inflammatory environment resulting in the recruitment and activation of both CAR T cells and mouse innate immune cells. We also show that the transgenes encoded by the virus are critical as synergy is lost in their absence.

Posterior scleritis and acute posterior multifocal placoid pigment epitheliopathy: A case of painful chorioretinitis and review of the current literature.

PURPOSE: To describe a patient who developed concurrent acute posterior multifocal placoid pigment epitheliopathy (APMPPE) and posterior scleritis. OBSERVATIONS: We describe a middle-aged woman that developed eye pain and photopsia. She was found to have a "T-sign" on ultrasound of the right eye and multiple, nearly confluent, ill-defined subretinal whitish lesions in both eyes. After an extensive laboratory evaluation and neuroimaging, her photopsia, pain with eye movements, and subretinal lesions began to regress on high dose systemic corticosteroids. CONCLUSIONS AND IMPORTANCE: This is the first reported case of bilateral APMPPE and concurrent posterior scleritis. Our case highlights the importance of performing a full review of systems, specifically eliciting neurological changes, and dilated eye examination in all new uveitis cases.

An anomalous foveal OCT-sign after posterior capsule rupture in cataract surgery: Complicated cataract surgery maculopathy.

PURPOSE: To report a series of novel optical coherence tomography (SD-OCT) foveal abnormalities, that we called "T-sign," that were noticed after a complicated cataract surgery with posterior capsule rupture and vitreous loss. METHODS: Retrospective case series of persistent foveal changes that incurred after anteroposterior vitreo-foveal traction secondary to phacoemulsification in presence of posterior capsule rupture. RESULTS: The study included three eyes of three patients that incurred in complicated cataract surgery and intraoperative vitreo-foveal traction. During 8-month follow-up period peculiar abnormalities in fundus examination and in OCT scans were reported in all cases. CONCLUSION: Phacoemulsification in presence of posterior capsule rupture could induce a vitreo-foveal strain that could be transmitted to the cone outer segment tips (COST line) and inner-outer segment (IS/OS) junction. This focal stress is liable for "T-sign," a persistent SD-OCT abnormality that induce a visual impairment and a slight metamorphopsia in the fixation point. SUMMARY STATEMENT: All over the world, more than 9.5 million cataract surgeries are completed each year.1 During surgery, many intraoperative complications could occur, and capsule rupture with vitreous loss is a frequent event. Phacoemulsification in presence of a wide posterior capsule rupture and vitreo-macular adhesion could induce a typical modification of the foveal structure and a permanent visual impairment.

Posterior Scleritis: Analysis of Epidemiology, Clinical Factors, and Risk of Recurrence in a Cohort of 114 Patients.

PURPOSE: To describe the clinical and epidemiological characteristics of patients with posterior scleritis, and to analyze the response to treatment and time to relapse. METHODS: Retrospective study of 114 cases of posterior scleritis from two tertiary care, university-affiliated, referral centers in the United Kingdom and India between 2004 and 2013. Data included sociodemographic factors, medical history, clinical, laboratory and ultrasound findings, therapies, and outcomes. LogMAR visual acuity at presentation and final visit and time to relapse were the main outcome measures. RESULTS: The mean age was 45.9 ± 16.8 years, 71.1% were women, and 18 (15.8%) patients had bilateral disease; 71 (62.3%) cases were idiopathic. Rheumatoid polyarthritis (12.28%), systemic lupus erythematous (4.38%) and pANCA(+) systemic vasculitis (5.26%) were the most frequent systemic associations. VA improved by 0.24 ± 0.36 LogMAR between presentation and last follow up (p < 0.001). The median time to remission was 210 days (95% CI: 184-256 days). Recurrences after remission were observed in 36.63%. The observed incidence rate of posterior scleritis relapse after remission was 15.81% per person-year (95% CI: 11.78-20.77%). Systemic disease was present significantly in patients more than 50 years of age (OR = 2.29; 95% CI: 1.01-5.17; p = 0.044). CONCLUSION: Posterior scleritis is an uncommon disease causing pain and visual loss. In around 40% of the cases, it can be associated with other systemic diseases. Median time to relapse was 210 days. Relapses may occur in around 1 in 3 patients, with an incidence rate of 15.81% per person/year.
