Genetics and Epigenetics of Graves' Orbitopathy

Graves Ophthalmopathy

Graves' orbitopathy (GO) is an autoimmune disease persisting when immunosuppression is achieved. Orbital fibroblasts from GO patients display peculiar phenotypes even if not exposed to autoimmunity, possibly reflecting genetic or epigenetic mechanisms, to be investigated here. Primary cultures of orbital fibroblasts from GO and control patients will be established. Cell proliferation, release of hyaluronic acid (HA) and HA synthases (HAS) will be measured. Next Generation Sequencing and gene expression analysis of the whole genome will be performed, as well as global DNA methylation assay.

Disappearance of Graves' Orbitopathy

Thyroid Eye Disease

There is a general belief among physicians involved with Graves' orbitopathy (GO) that this syndrome is somehow "chronic", namely that the patient's eyes do not return the way they were before GO appeared. The general impression that comes from the available studies is that the eyes of GO patients do not return to normal even after a very long time since the disease appearance under the physician's point of view, although a discrete proportion of patients feel so. However, no studies are available in which the issue was examined with both objective criteria and self-assessment. The present study design was to investigated the disappearance of GO, regardless to treatment, in all consecutive patients with a history of GO of at least 10 years who came for a follow-up visit to our GO clinic over a period of 5 years.

Studies of the Angle Kappa and the Angle Alpha

No Eye Disorder

Anatomical ophthalmological connections and their dynamics are still debated in the scientific community. However, their considering is essential in many surgeries (strabismus, cataract, refractive...) or in clinical practice. The correlation between these biometric values would make it possible to refine the knowledge related to these landmarks and thus offer better ophthalmological management by integrating these variables into the clinical examination. The aim of the study is to analyze the correlation between the angle alpha and the angle kappa in a healthy individual without ophthalmologic disorder.

The Flashing Light-Induced Pupil Response (FLIPR) Glaucoma Study

GlaucomaOpen-Angle1 more

This study is designed to investigate whether the pupil response to slowly flashing colored lights is significantly altered in patients with glaucoma, as compared to a control group of subjects without glaucoma.

TearLab Core Validation Study to Establish Referent Values for Dry Eye Disease

Keratoconjunctivitis Sicca

This is a prospective, observational case series to determine the clinical utility of tear osmolarity and other commonly used objective tests to diagnose dry eye disease, as well as to establish referent values for objective tests of the disease.

Patient Specific Induced Pluripotency Stem Cells (PSiPS)

Hepatic DisordersEye Disorders

Induced pluripotent stem cells (iPSCs) are adult cells that have been genetically reprogrammed to an embryonic stem cell-like state by being forced to express genes and factors important for maintaining the defining properties of embryonic stem cells. The reprogramming of adult cells into embryonic stem (ES) cells enables the generation of patient-specific stem cells and thus has enormous potential for the treatment and analysis of degenerative diseases. In this project the investigators are going to induce pluripotent stem cells from cell cultures from skin biopsies of patients. The iPS cells will be developed for modeling diseases and drug discovery as well as basic research.

Diurnal Variation in Tear Osmolarity

Dry Eye Disease

The purpose of this study is to measure the change in Tear Osmolarity during the course of the day to support clinical diagnosis of aqueous deficiency or meibomian gland disease and differentiate between the two forms of dry eye.
