Equine eyelid reconstruction by semi‐circular skin flap blepharoplasty

Equine Veterinary Education, EarlyView.
Summary Reconstructive surgeries of the equine eyelid carry significant challenges for the equine surgeon, due to the poorly mobile and tightly adhered facial skin in this species. Preservation of lid function is an essential surgical consideration in order to maintain protection of the globe and cornea and to provide ocular comfort to the case ...

Age and disease-related structural changes in the retinal pigment epithelium

, 2008
Vera L BonilhaCole Eye Institute, The Cleveland Clinic, Cleveland, OH, USAAbstract: As the retinal pigment epithelium (RPE) ages, a number of structural changes occur, including loss of melanin granules, increase in the density of residual bodies ...

Epidermoid cyst as differential diagnosis for spherical keratoma: What do we know?

Equine Veterinary Education, EarlyView.
Summary This article briefly presents the case of a space‐occupying coronary band mass that raised the question of how one can differentiate between two uncommonly seen but now commonly paired differential diagnoses and prompted a review of the relevant literature.

The positive correlation between the progressive photoreceptor damage and the increased macular leakage indicating the severity of diabetic retinopathy

Journal of Diabetes Investigation, EarlyView.
The dark area of photoreceptor cells, as measured by adaptive optics laser scanning ophthalmoscopy, shows significant enlargement with the progression of diabetic retinopathy (DR). A similar trend is observed for macular vascular leakage assessed by fundus fluorescein angiography. A positive correlation exists between these two parameters, suggesting a

Cyclic GMP in the pig vitreous and retina after experimental retinal detachment

, 2008
Purpose: Earlier studies have revealed a decreased level of cGMP in vitreous fluid obtained from patients with a retinal detachment. To further investigate this phenomenon, we developed an experimental retinal detachment model in pigs.

Ocular Manifestations of Infectious Salmon Anaemia Virus Infection in Atlantic Salmon (Salmo salar)

Journal of Fish Diseases, EarlyView.
ABSTRACT Eyes are essential sensory organs needed by teleost Atlantic salmon for high visual acuity and survival in both the wild and in aquaculture settings. In this work, we assessed the ocular manifestations of Infectious Salmon Anaemia Virus (ISAV) infection in Atlantic salmon by a cohabitation‐mediated infection assay and histological and ...

Molecular characterization of the mouse tyrosinase gene: pigment cell-specific expression in transgenic mice

Tyrosinase is the key enzyme in melanin synthesis, and is expressed in the pigment epithelium of the retina, a cell layer derived from the optic cup; and in neural crest-derived melanocytes of skin, hair follicle, choroid, and iris.

20th Anniversary of human‐induced pluripotent stem cells and the role of microscopy

Journal of Microscopy, EarlyView.
Abstract It has been 20 years since the pioneering work of Shinya Yamanaka and Kazutoshi Takahashi at Kyoto University led to the first successful generation of induced pluripotent stem cells (iPSCs) from mouse embryonic and adult fibroblast cells. iPSCs have the capacity to differentiate into any type of cell in the human body, and as such, they have ...

Neural modulation of ocular immunity: Exploring a sympathetic‐macrophage neuroimmune link in the human ciliary body

Journal of Anatomy, EarlyView.
Using microscopy and 3D confocal imaging on seven cadaveric eyes, we identified sympathetic nerves closely associated with β₂‐adrenergic receptor‐expressing macrophages in the human ciliary body (CB). These findings suggest a sympathetic‐macrophage neuroimmune link in the CB, potentially influencing ocular inflammation and degeneration, warranting ...
