To study the relationship between visual function and ocular (iris, retina/choroidal) pigmentation in patients with albinism and other hypomelanotic disorders. To identify the carrier state in relatives of patients with ocular albinism.
Oculocutaneous albinism (OCA) is a term used to describe inherited forms of hypopigmentation associated with 1) variable levels of cutaneous hypopigmentation, ocular hypopigmentation, and visual deficits, and 2) involvement of both of the major developmental types of pigmented cells, i.e., melanocytes and retinal pigment epithelium. OCA is considered isolated if it involves only tissues that are normally pigmented. The four known types of isolated oculocutaneous albinism (OCA-1...
The purpose of this study is to determine whether the structure and function of the human retina can be studied with high resolution in patients with inherited retinal degenerations using the Adaptive Optics Scanning Laser Ophthalmoscope (AOSLO).
Hermansky-Pudlak Syndrome (HPS) is an inherited disease which results in decreased pigmentation (oculocutaneous albinism), bleeding problems due to a platelet abnormality (platelet storage pool defect), and storage of an abnormal fat-protein compound (lysosomal accumulation of ceroid lipofuscin). The disease can cause poor functioning of the lungs, intestine, kidneys, or heart. The major complication of the disease is pulmonary fibrosis and typically causes death in pat...
Laser photocoagulation has become the treatment of choice in PDR. Laser photocoagulation has become the treatment of choice in PDR. The aim is to destroy a substantial portion of the peripheral retina in order to reduce the angiogenic stimulus (decrease the difference between oxygen demand and the administration). Their effectiveness is determined by the extent of destruction of the retina (2.4).

The investigators developed an ultra-speed picosecond laser (20ps) with a 20gHz repetition rate that provide very promising results in vitro and in ex vivo skin to remove skin tattoos. The aim of this study is to evaluate the efficacy and tolerance of a new ultra-speed picosecond laser and to compare it to a nanosecond laser for treating black tattoos. In a first phase of the study 10 patients with black tattoos will be treated with increasing fluencies of the picosecond lase...
To develop a database of the peripheral retinal circulation using ultra widefield fluorescein angiography (UWF-FA) imaging for the Optos COE platform. This database will serve as a quantitative reference tool for the comparison of subjects to a database of known normal subjects.
ROP is a preventable cause of blindness in premature infants. It is routinely screened for by using an indirect ophthalmoscope, a scleral depressor, and a condensing lens. This method of screening can cause significant cardiorespiratory distress to infants. A new camera (Optos California) has recently been used to image infants with different severities of ROP. The Optos California is capable of capturing up to 200 degrees of retina in a single image without contact with the ey...
Optical Coherence Tomography (OCT) is an established non-invasive medical imaging technique ophthalmologists use to diagnose and monitor retinal diseases such as age-related macular degeneration (AMD). This study assesses the scanning performance of a newly developed sparse OCT retina scanner that is smaller and more compact than most commercially available medical OCT systems. The prototype device was developed at Artorg Center Bern and Berner Fachhochschule Biel. In t...

In the present study, 60 eyes will be randomized and blinded into 2 groups, one receiving up to two sessions of laser vitreolysis the other scheduled for two sessions of sham treatment. After a maximum of two (sham) treatment sessions ...
Laser therapy is an established method to stabilize and control proliferative diabetic eye disease. Questions on the long-term effect on the retina from these treatments remain to be answered. The purpose of the study was to evaluate changes in the retina following panretinal photocoagulation (PRP) over time, using structural and functional diagnostic tests.
The goal of this clinical research study is to evaluate fluorescence imaging, widefield fluorescence imaging, point spectroscopy imaging methods, and or/ oral brush cytology that may help doctors monitor patients at an increased risk of developing an oral cancer, including those with pre-cancerous lesions in the mouth.
Confocal laser endomicroscopy (CLE) is a newly endoscopic device that enables microscopic view of the digestive tract. The purpose of this study is to determine if confocal laser endomicroscopy can improve detection of digestive disease include inflammation, dysplasia, and early cancer, and if confocal laser endomicroscopy has competitive advantage, compared with other device such as Narrow Band Imaging and Autofluoresecence Imaging.
Recently, three-dimensional scanning of the torso has been proposed as an alternative for two-view chest radiographies and computed tomography to determine the severity of pectus excavatum without exposure to ionizing radiation. The range of three-dimensional scanning systems is broad with even varying systems being used within hospitals. Most of these scanning systems have been validated for accuracy and reproducibility, no comparison between these systems is known. In additio...

Ultrasound imaging (US), a radiation-free imaging modality, is currently used in diagnosis of developmental dysplasia of the hip (DDH) in infants. The current protocol involves manually identifying specific measures that are prone to error, and may give rise to false positives. We aim to use 2-dimensional (2D) and 3-dimensional (3D) ultrasound imaging to create an automatic measurement procedure that we hope will reduce the errors in measurement and increase reliability.
