Trial: Effect of Prophylactic Ketorolac on CME After Cataract Surgery
Purpose: The study will evaluate the efficacy of prophylactic administration of the topical nonsteroidal anti-inflammatory drug (NSAID) ketorolac tromethamine 0.5% (Acular; Allergan, Irvine, Calif) on cystoid macular edema (CME) in patients having undergone cataract surgery. CME is the most frequent cause of decreased vision after uncomplicated cataract surgery and can result in irreversible sight reduction. The investigation will involve a comparison arm and a treatment arm with both sets of patient populations being evaluated for CME with ophthalmologic examinations and OCT measurements. The objective is to elucidate the role of NSAID drops in preventing CME after cataract surgery.
Sponsor: Queen’s University
Design: Prevention, randomized, open-label, placebo-control, single-group assignment
Number of patients: 100
Inclusion/exclusion criteria: First cataract surgery (ie, first eye). Exclusion criteria: any preexisting retinal/macular disease, ocular tumours,
uveitis, hypersensitivity to the NSAID drug class, pregnancy or previous intraocular surgery.
Status: This trial is recruiting patients.

Study: Tissue Studies of Human Eye Diseases
Purpose: The purpose of this study is to better understand the processes involved in the development of various eye conditions, such as uveitis, disorders of the conjunctiva, cornea, vitreous and retina, metabolic or genetic eye diseases or eye tumors, in order to develop better methods of diagnosis and treatment. Patients who require eye surgery to treat an eye disease or other disease in which the eye is involved may participate in this study. Samples of eye tissue and fluid that are normally removed and discarded during eye surgery will instead be given to researchers for study. The tissues will be examined under microscope and studied using sophisticated chemical and biological tests. Immune cells from blood samples may also be examined. These studies will help better understand and diagnose the various eye diseases and to develop more attractive therapies.
Sponsor: NEI
Design: Observational, natural history
Number of patients: Not given
Inclusion/exclusion criteria: All specimens either male or female of any age with ocular disease that are collected at the NEI or its collaborating institutes, will be included in the study. Specimens would consist of material obtained from surgical specimens, biopsy specimens, and from post mortem materials. These would include but would not be limited to cases involving uveal, conjunctival, corneal, vitreoretinal, orbital disorders, tumor and metabolic abnormalities.

Trial: Molecular Genetics of Retinal Degenerations
Purpose: This multinational study will investigate the inheritance of genetic retinal degeneration in families of different nationalities and ethnic backgrounds in order to identify the genes that, when altered, cause retinal degeneration. The findings of this study should help improve diagnosis and methods of treatment for these disorders. Participating institutions include: the National Institutes for Health in Bethesda, Maryland; the University of Miami in Florida; the Casey Eye Institute in Portland, Oregon; the Byrd Health Sciences Center in Morgantown, West Virginia; the University of Texas Southwestern Medical School in Dallas, Texas; the University of Tennessee Health Sciences Center in Memphis; the Prasad Eye Institute in Hyderabad, India; National Center of Excellence in Molecular Biology in Lahore, Pakistan; and the Jules Gonin Hospital in Lausanne, Switzerland. Patients with retinitis pigmentosa and closely related diseases such as Usher syndrome, snowflake vitreoretinal dystrophy and Bietti crystalline dystrophy may be eligible for this study.
Participants undergo the following tests and procedures: Medical and surgical history, including family history of vision problems. Examination to clarify the type of retinal degeneration. Eye examination, including tests of color vision, field of vision and ability to see in the dark Electroretinogram to test the function of visual cells. Hearing tests for patients with a personal or family history of deafness. For middle ear function testing, the patient feels a little air pressure change for a moment and hears some tones. Another test requires the patient to sit quietly with electrodes on the head, forehead and earlobes. Balance testing, including walking in a straight line, standing with eyes closed in the dark and other tests of coordination, and caloric testing. For the caloric testing, any ear wax in the ear canal is removed before the test begins. Then, electrodes are placed on the skin near the eyes and on the forehead. A small amount of cool (sometimes cold) or warm water is instilled into each ear canal, first one and then the other. Blood sample collection for genetic testing.
