Clinical, Cellular, and Molecular Investigation Into Oculocutaneous 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...

Clinical and Basic Investigations Into Hermansky-Pudlak Syndrome

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...

Changes in Electroretinogram and Contrast Sensitivity After PASCAL Treatment

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).

Changes in Macular Thickness After Patterns Scan Laser

Laser photocoagulation has become the treatment of choice in PDR. Laser photocoagulation has become the treatment of choice in TMD. 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).

Evaluation of an Ultra-speed Picosecond Laser for Treating Tattoos

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...

ObseRvation of PeripHEral rEtinal Morphology in Normals

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.

Optos Versus Indirect Ophthalmoscopy for ROP Screening Examination (Optos vs BIO Study)

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...

Assessment of Scan Quality of Sparse OCT Retina Scanner (MimoStudy01)

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...

Automatic Characterization of the Neonatal Hip Using Ultrasound Imaging

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.
