NCT ID: NCT05736237 Recruiting - Optic Disk Drusen Clinical Trials

Identification and Verification of Candidate Genes Responsible for Optic Disc Drusen Development

GENODD
Start date: May 1, 2023
Phase:
Study type: Observational

The goal of this observational study is to learn about the genetic background for the development of optic disc drusen. The main question is: • Can one or more candidate genes be found? Participants will have a blood sample taken and answer a questionnaire.

NCT ID: NCT05305079 Recruiting - Clinical trials for Non-arteritic Ischemic Optic Neuropathy

NA-AION Risk Factors: New Perspectives

NARROW
Start date: August 1, 2021
Phase:
Study type: Observational

The purpose of the study is to use new diagnostic methods (OCT and OCT-A) to shed light on risk factors for the development of NA-AION. The risk factors we are focusing on are comorbidities along with anatomical and vascular characteristics of the optic nerve.

NCT ID: NCT03957642 Recruiting - Optic Disk Drusen Clinical Trials

Systematic Imaging Examination in ODD

Start date: May 21, 2019
Phase:
Study type: Observational

To evaluate the diagnostic value of systematic ophthalmologic imaging examination in the diagnosis of embedded optic disc drusen (ODD) in adolescents with mild visual impairment.

NCT ID: NCT02793206 Completed - Optic Disc Drusen Clinical Trials

Spectral Domain OCT Imaging in Patients With Optic Nerve Head Drusen (Tuebingen SD-OCT IN OPTIC NERVE HEAD DRUSEN STUDY)

TODS
Start date: August 1, 2011
Phase: N/A
Study type: Observational

Optic nerve head Drusen are a mostly bilateral change of the optic nerve, eventually causing a slow, but progression loss of the visual fields. Characteristic are the crystalline deposits at the entrance of the optic nerve, the so called optic disc. The material consists of calcium, calcium phosphate, iron, but also amino acids and polysaccharides. The diagnose is made or confirmed by different imaging modalities like ultrasound and auto-fluorescence imaging. By using the high-resolution imaging with spectral-domain optical coherence imaging (SD-OCT) the volume and deposits at the optic disc can be measured and quantified. The purpose of this study whether and how defects in the visual fields are related to the deposits. Multimodal imaging of the optic nerve head is planned within the cross-sectional study, at two different time intervals (2 years). Changes in retinal fibre layer (RNFL) thickness and disc parameters are analyzed. Presence and extent of auto-fluorescent changes are evaluated. The prospective trial wants to clarify whether certain parameters at baseline indicate the further outcome and development.

NCT ID: NCT01673815 Completed - Clinical trials for Other Disorders of Optic Disc, Bilateral

Video Diversion During Fundoscopic Exam in Children

CAFE
Start date: August 2011
Phase: N/A
Study type: Interventional

Fundoscopy is an important aspect of the neurological examination, but can be challenging in uncooperative children. This study explored whether viewing a video (selected by patient or caregiver) during eye examination improves the success, duration and ease of pediatric fundoscopy. Hypothesis: Showing a short video clip during a fundoscopic exam will increase the probability of successfully visualizing the optic disk and reduce the amount of time needed to perform a fundoscopic exam in children between 1-8 years old.
