Color Vision as a Measure for Inherited Retinal Diseases

Background: - The purpose of this study is to find out whether color vision measured with the Cambridge Color Test is a good way to examine the severity of inherited retinal diseases (IRDs). IRDs are a major cause of vision loss worldwide, but very little is known about how the diseases affect color vision over time. This study will tell us if color vision may be used to track changes in inherited retinal diseases over time. Objectives: - To improve understanding...


Chemotherapy Treatment for Children With Intraocular Germ-Line Retinoblastoma

Retinoblastoma is an unusual cancer of early childhood involving tumor is both eyes or, in certain circumstances, one eye only. This condition is the result of an abnormal gene which makes both retinas (the back of the eye) vulnerable to develop multiple tumors. Growths in the eye impair vision temporarily or permanently. These tumors are malignant, which means that they can grow within the eye, spread outside of the eye, and be fatal if untreated. Standard therapy for bilater...

Binocular Vision in Monocular Pseudophakia

Following cataract surgery, an intraocular lens (IOL) is implanted in the eye. The majority of people develop an operable cataract when they are over the age of 50. Occasionally people under 50 years develop a cataract requiring an operation. The visual demands in this age group are very different due to both physiological and lifestyle factors. Traditionally IOLs are focussed for distance vision and additional spectacles are worn for near vision. Under the age of 45 years we h...


Effect of Clemastine Fumarate on Color Vision in Healthy Controls

In a1972 study in the French Annals of Pharmaceuticals, Laroche and Laroche reported that the drug clemastine has a negative effect on patients' color discrimination, which is the ability to distinguish different hues and arrange them in the correct order. In an upcoming clinical trial studying the effect of clemastine on vision outcomes, our lab aims to assess color visual performance adding assessment of color defectiveness as a clinical endpoint. Color defectiveness is the a...

Assessment of Color Vision in Diabetic Patients

Assessment of color vision in diabetic patients before and after the use of anti-vegf in the treatment of diabetic macular edema

Ocular Screening in Children and Young Adults at Risk for Increased Intracranial Pressure

The purpose of this study is to evaluate the vision and posterior segment of eyes in children and young adults less than 22 years of age with risk, suspicion, or past medical history significant for elevated intracranial pressure (ICP). Patients will have visual acuity and color vision tested. Assessment of the posterior segment will involve using a non-invasive (non-contact) imaging technique (i.e. a portable fundus camera in clinic and hospital settings).

Intervening Factors in Tooth Color Assessment

The aim of this study is to evaluate the influence of several factors (light, extrinsic stain removal and operator's experience) in tooth color assessment. Tooth color will be assessed by two different operators with visual shade guides under standardized light conditions and using a light correcting device (Smile Lite) or with a dental spectrophotometer in human subjects. Color measurement will be made before and 1 week after dental prophylaxis.

DRCR.Net Aflibercept vs. Bevacizumab + Deferred Aflibercept for the Treatment of CI-DME

Both aflibercept and bevacizumab have been shown to improve vision in eyes with DME. In eyes with DME and at least moderate vision loss, both aflibercept and bevacizumab were also shown to be successful in many eyes. However, aflibercept was shown to be more effective at improving vision, on average, at 1 year and at 2 years. Due to the large cost difference between the two drugs, many clinicians and patients are choosing to initiate treatment with bevacizumab and then switch t...

Visual Cortex Stimulation in Patients With Amblyopia

This study will examine whether direct current (DC) polarization (electrical stimulation) of the visual cortex can cause a temporary improvement of vision in an amblyopic eye of an adult. Amblyopia (also called lazy eye) is reduced vision in an eye, caused by abnormal brain processing of visual information. In amblyopia, the visual cortex (the part of the brain that processes visual information) favors the other eye and suppresses the image from the amblyopic eye. Amblyo...

Study of Usher Syndromes, Type 1 and Type 2

The purpose of this investigation is to gain additional knowledge about what causes type 1 and type 2 Usher syndrome-inherited diseases that can cause balance problems and impaired hearing and vision-and to develop better diagnostic tests. Patients with type 1 Usher syndrome usually are deaf from birth and have speech and balance problems. Patients with type 2 disease generally are hearing impaired but have no balance problems. All patients develop eye problems that cause di...

Ability of Patients With Low Vision to Properly Instill Eye Drops

The investigators are interested in seeing how people with low vision (decreased visual acuity or restricted visual fields) instill eye drops into their own eyes. The investigators hypothesis is that this population will have more difficulty with self-instillation of drops than a better-seeing population. The investigators aim to explore whatever factors may be involved in preventing this population from getting prescribed eyedrops into their eyes, whether it is more related to...

Test-retest Reliability of Two Measurements of the Visual System

Binocular vision tests are guided by the principle that uniform motion and focus of the eyes may be trained, but exercising the simultaneous movement of the pupils is necessary and important in achieving optimal and lasting results (Horwood & Toor, 2014). These tests have been in use for over 70 years and represent the foundation of therapy for visual deficiencies such as the inability of the eyes to move together. Despite their frequent use, no one has ever formally evaluated ...

Clinical and Genetic Studies of X-Linked Juvenile Retinoschisis

This study will explore the causes and eye problems of X-linked juvenile retinoschisis (XLRS), an inherited disease that causes vision loss primarily in young males. The vision loss, which worsens over time, is a result of schisis, or splitting, of the layers of the retina (tissue that lines the back of the eye). A better understanding of why and how XLRS develops might lead to improved treatments. Patients 9 months of age and older with XLRS and females who are suspected ca...

Amblyopia (Lazy Eye) Treatment Study

The purpose of this study is to compare the results of two standard treatments for amblyopia in order to find out if one is more effective than the other. Amblyopia, which develops in childhood, is also called "lazy eye," because one eye is not being used properly. The brain favors the other eye for some reason, such as crossing or turning out of the eyes, and vision in the weak eye is reduced. Amblyopia is treated by forcing the child to use the weak eye. There are two way...

In Vitro Human Embryo Culture System

The purpose of this study is to compare the development of human embryos grown in a conventional culture dish to those grown in a new embryo culture device known as the SMART System.

Study of Dark Adaptation in Age-Related Macular Degeneration

Background: - Age-related macular degeneration (AMD) is a leading cause of vision loss in individuals over 55 years of age. It can cause permanent loss of central vision, which is important for seeing fine details and long distances. AMD has two forms: wet AMD and dry AMD. Most people with AMD have dry AMD. But dry AMD can progress to wet AMD. Wet AMD is the more serious form and can result in severe vision loss. - A method to identify and moni...

Cysteamine Eye Drops to Treat Corneal Crystals in Cystinosis

This study will continue to evaluate the long term safety and effectiveness of cysteamine eye drops for treating cystine crystals in the corneas of patients with cystinosis. These drops are not sold commercially and are available only through this study. New patients may enroll in the study to obtain them. Cystinosis is an inherited disease that results in poor growth and kidney disease, among other things. The damage to the kidneys and other organs is thought to be due to ...

A Study to Test the Potential of Brillouin Microscopy for Biomechanical Properties Measurements in Human Cornea

The purpose of this research study is to find out if the new Brillouin Ocular Scanner can measure the variation (difference) of the corneal elastic changes involved in the onset of corneal ectasia, induced by LASIK surgery and cornea collagen crosslinking (CXL) treatment. Ectasia refers to the thinning and bulging of the cornea and results in severe vision degradation (loss), which may occur because of a progressive disease (keratoconus) or because of LASIK surgery. It is belie...

In Vivo Assessment of Natural Tooth Color After Orthognathic Surgery. A Pilot Controlled Clinical Trial

In six consecutive patients planned to receive combined orthodontic-orthognathic surgery natural tooth color on 8 incisors was measured before initiation of the combined treatment (Time Point 1- baseline) and after its completion (Time Point 2- after intervention). The statistical interpretation of the results showed that tooth color change in the surgical group was higher in comparison to control groups. Control group I included non treatment subjects, while control group II i...

Low Vision Depression Prevention Trial for Age Related Macular Degeneration

This randomized, controlled clinical trial, the Low Vision Depression Prevention TriAL (VITAL), will test the efficacy of collaborative low vision rehabilitation (LVR) to prevent depressive disorders in Age-Related Macular Degeneration (AMD). In this innovative intervention, a low vision occupational therapist collaborates with a low vision optometrist to develop and implement a care plan based on a subject's vision status, rehabilitation potential, and personal rehabilitation...

Fluocinolone Implant to Treat Macular Degeneration

This study will test the safety and effectiveness of a fluocinolone implant to treat age-related macular degeneration. This eye disease can severely impair central vision, affecting a person's ability to read, drive, and carry out daily activities. It is the leading cause of vision loss in people over age 60. The fluocinolone implant is a tiny plastic rod with a pellet of the steroid fluocinolone on the end. The pellet slowly dissolves and releases the medication into the f...

Pilot Assessment of EyeArt as an Automated Diabetic Retinopathy Screening Tool

More than 29 million people in the US are living with diabetes, many of whom will develop diabetic retinopathy (DR) or diabetic eye disease (DED), the leading cause of vision loss and blindness in working-age adults. Annual eye screening is recommended for all diabetic patients since vision loss can be prevented with laser photocoagulation and anti-VEGF injections if DR is diagnosed in its early stages. Currently, the number of clinical personnel trained for DR screening is ord...
