The IRIS™ Registry (Intelligent Research in Sight) is the nation's first comprehensive eye disease clinical registry. The American Academy of Ophthalmology is developing it as part of the profession's shared goal of continual improvement in the delivery of eye care.The IRIS Registry will be a centralized system for ophthalmology practices to promote practice innovations and achieve clinical excellence.
Background: Research has identified some of the genes involved in inherited eye diseases. But for many of these diseases, the genes are not yet known. Researchers want to try to find these genes. They also hope to learn more about how symptoms differ in people with similar gene changes. Objective: To learn more about genes involved in eye diseases. Eligibility: People who have a known or suspected inherited eye disease, and their relatives. Design: - All participants will have a medical history, physical exam, and eye exam. They may have blood taken. - Participants with an eye disease may have eye cell samples taken using a swab or biopsy procedure. - Participants may have a skin biopsy. A (Omega)-inch piece of skin will be removed. - Participants may have blood drawn and the red blood cells removed. The remaining serum will be made into an eye drop solution for the participant. - Participants may provide samples of tears, urine, saliva, stool, hair, or inner cheek cells. - Participants may have a retina test. They may also have a test that uses light to measure retina thickness. - Participants may have an eye movement test. Electrodes will be placed on the skin next to both eyes. - Participants may have a fluorescein angiography. A dye will be given through an intravenous line in the arm. A camera will take pictures of the dye as it flows through the eyes blood vessels. - Participants may have microperimetry. They will sit at a computer screen and press a button when they see a light. - Participants may have an eye movement test. They will wear contact lenses or goggles and watch a series of spots on a computer screen.
Peribulbar anaesthesia for ocular surgery depends on the spread of local anaesthetic throught the orbit to be successful and has a relatively high failure rate. This study will examine a novel ultrasound guided approach to peribulbar anaesthesia which should extend the depostion of local anaesthetic by using a dual quadrant injection technique. The study will assess the feasibility of this technique, how successful it is and whether any obvious safety issues arise with its use.
The My Retina Tracker® Registry is sponsored by the Foundation Fighting Blindness and is for people affected by one of the rare inherited retinal degenerative diseases studied by the Foundation. It is a patient-initiated registry accessible via a secure on-line portal at www.MyRetinaTracker.org. Affected individuals who register are guided to create a profile that captures their perspective on their retinal disease and its progress; family history; genetic testing results; preventive measures; general health and interest in participation in research studies. The participants may also choose to ask their clinician to add clinical measurements and results at each clinical visit. Participants are urged to update the information regularly to create longitudinal records of their disease, from their own perspective, and their clinical progress. The overall goals of the Registry are: to better understand the diversity within the inherited retinal degenerative diseases; to understand the prevalence of the different diseases and gene variants; to assist in the establishment of genotype-phenotype relationships; to help understand the natural history of the diseases; to help accelerate research and development of clinical trials for treatments; and to provide a tool to investigators that can assist with recruitment for research studies and clinical trials.
ASTED (Antioxidant Supplements for TED) trial is an investigator-initiated, randomized, triple masked, clinical trial of a selected combination of vitamins and minerals versus placebo in patients with moderate to severe thyroid eye disease. The trial has a parallel-arm design.
Millions of people suffer from dry eye disease, causing symptoms such as redness, burning, feeling of sand or grit in the eye and light sensitivity. Dry eye disease occurs when your eyes do not produce enough tears or produce poor quality tears. This can happen for a number of reasons, including aging, hormonal changes in women and side effects of diseases or medications. It is now possible to objectively measure the degree of dry eye disease by collecting a tiny sample of tears from the corner of the eye and then measuring the amount of salt in the tears (termed osmolarity). We aim to establish the overall levels of raised and normal tear osmolarity in people presenting to the eye clinic with complaints of dry eye, and relate this to other factors such as symptoms, topical and nutritional medication and dry eye treatment.
This is a randomized, double masked study designed to evaluate the safety of EBI-005 5 mg/mL topical ophthalmic solution given three times daily (TID) compared to vehicle-control over a one year period in subjects with dry eye disease (DED). Approximately 188 subjects will be enrolled to either EBI-005 or vehicle at up to 15 centers in the United States (US) and Canada.
The dysthyroid orbitopathy (DO) is a chronic disease, evolving during 2 to 3 years, with a hypertrophy and a variable degree of inflammation of the eyelid muscles, the oculomotor muscles and the orbital fat. If the diagnosis of OD is primarily clinical and laboratory, MRI is an additional contribution to the clinic, guiding the therapeutic management by detecting inflammatory lesions not found on clinical examination in 1/3 of cases. The three MRI sequences conventionally practiced ((T2, T2-fat-sat, T1) allow muscles signal analysis oculomotor abnormalities as well as the orbital fat. Compared to these sequences, the main advantage sequences DIXON is a faster acquisition. In addition, DIXON type of imaging overcomes most of these artifacts and to obtain a homogeneous fat removal.
This randomized clinical trial is designed to evaluate the effect of selected antioxidant vitamins and minerals supplement named as ASTED: 1. β- Carotene (30 mg) 2. Vit C (100 mg) 3. Vit E (Alpha-Tocopherol Acetate): 60-200 IU 4. Calcium phosphate dihydrate (40 mg) 5. Zinc oxide (4 mg, elemental) 6. Copper gluconate (3.5 mg) 7. Sodium selenite 23 mg= Selenium 100 µg 8. Nicotinamide (a form of vit.B3) (10 mg) in patients with mild Thyroid eye disease according to EUGOGO classification. To be given twice a day.
