Anterior stromal fibrosis is often seen in advanced cases of Fuchs endothelial dystrophy or secondary endothelial insufficiency. As Descemet membrane endothelial keratoplasty (DMEK) can completely eliminate the corneal edema and the guttae in these patients, anterior stromal fibrosis often remains leading to a reduction in visual function.

In such situations phototherapeutic keratectomy can be an effective tool to remove the opacifications in the anterior corneal stroma and improve the visual function as presented in two clinical cases.

DMEK can be the method of choice even in advanced cases of endothelial insufficiency with clinical significant fibrosis of the anterior corneal stroma.

To describe the findings of long-term follow-up of a case of amyloidosis-associated chorioretinopathy by multimodal imagings, including optical coherence tomography (OCT).

A 47-year-old woman who had been diagnosed as having systemic amyloidosis was found to have a best corrected visual acuity of 20/13 in both eyes at the age of 41, which subsequently decreased to 20/100 in the left eye and 20/20 in the right eye at age 47. Visual field examination demonstrated worsening of the central scotoma during the follow-up period. Funduscopic examination revealed bilateral white deposits along the choroidal vessels, which became more pronounced over time, along with diffuse pigmentary changes. The fluorescein angiography and indocyanine green angiography findings were consistent not only with atrophic lesions, but also with amyloid deposition (i.e., staining of the vessels).At the baseline, macula OCT revealed a thick hyporeflective band at the choriocapillaris, however, at the last follow-up, it revealed an absent ellipsoid zone, and bilateral progressive retinal pigment epithelium irregularities in both eyes.

Patients diagnosed as having amyloidosis-related chorioretinopathy may have maintained visual function at the first detection of retinal amyloid deposition, and a number of years may elapse before the patient manifests visual deterioration.

To describe the multimodal imaging (MMI) findings and clinical course of a case of Multiple Evanescent White Dot Syndrome (MEWDS) following immunization with inactivated intra-dermal influenza virus, and to explore whether similarities exist with other, previously reported cases.

A 34-year-old Caucasian man presented with unilateral onset of para-central scotomata, photopsias, and dyschromatopsia two weeks after administration of an influenza vaccine. Clinical examination and MMI were indicative of MEWDS. PF-562271 nmr The patient's MMI abnormalities and symptoms resolved spontaneously after four weeks.

This is the first reported case of MMI of post-influenza vaccination-associated MEWDS. Comparison with eight previously reported cases of MEWDS following various immunizations revealed that subjects tended to be healthy, young to middle age women with a median time to onset of two weeks. Vision tended to recover spontaneously over one to three months.

The non-arteritic form of anterior ischemic optic neuropathy (AION) is the most common acute optic neuropathy among individuals over the age of fifty, yet little is known about how the disorder affects color vision. We tested the hypothesis that color vision correlates with visual acuity in patients with non-arteritic AION. We also evaluated the patterns of visual field loss in a subgroup of patients who manifested relative sparing of color vision.

Records of forty-five patients with non-arteritic AION who had been evaluated at Duke University over a consecutive four-year period were reviewed retrospectively. Statistical analysis of the relationship between color vision and visual acuity was carried out using a linear regression model. Color vision tended to correlate with acuity with respect to visual acuities between 20/16 and 20/63. However, nine patients were identified in whom color vision was relatively spared in comparison with acuity. Most of the affected eyes in this subgroup had a distinctive pa results of color vision testing in patients with non-arteritic AION help to differentiate this condition from other optic neuropathies such as optic neuritis.Growth literature often uses the Brody, Gompertz, Verhulst, and von Bertalanffy models. Is there a rationale for the preference of these classical named models? The versatile five-parameter Bertalanffy-Pütter (BP) model generalizes these models. We revisited peer-reviewed publications from the years 1970-2019 that fitted growth models to together 122 mass-at-age data of sheep and goats from 19 countries and studied the best-fit BP-models using the least-squares method. None of the named models was ever best-fitting. However, for 70% of the data a single non-sigmoidal model had an acceptable fit (normalized root mean squared error 〈 5% and F-ratio test 〉 5% in comparison to the best-fit) the Brody model. The inherently non-sigmoidal character was further underlined, as there were only 39% of the data, where the best-fitting BP-model had a discernible inflection point. For these data, conclusions of biological interest could be drawn from the sigmoidal best-fit BP-models the maximal weight gain per day was about 55% higher than the natal weight gain per day.Adults with central adiposity and other features of the metabolic syndrome have a markedly elevated risk of developing type 2 diabetes (T2D) and cardiovascular disease (CVD). A Mediterranean-style healthy eating pattern (MED-HEP) and consumption of foods with a lower glycemic index (GI) are potential dietary approaches to curb the T2D and CVD epidemic. However, experimental evidence of the effectiveness of MED-HEP and of the contribution of GI towards improving indices of glucose homeostasis, especially among non-diabetic people, are lacking. Therefore, we developed the MedGI-Carb trial, a multi-center (Italy, Sweden, and United States) intervention in adults with at least two components of the metabolic syndrome (elevated waist circumference + one other component) that aims to improve markers of glucose homeostasis through dietary modification. All participants were randomized to consume an isocaloric high- or low-GI MED-HEP for 12 weeks. We hypothesized that indexes of insulinemia (primary outcome postprandial insulin and glucose after standardized breakfast and lunch; secondary outcomes fasting plasma glucose and insulin, HbA1c, 24-h continuous glucose monitoring) would be improved more with the low-GI versus the high-GI MED-HEP.
