简要总结

Aim

  • To investigate repeatability and stability of the six OTH-related Bulbicam tests in patients suffering from a) Diabetic retinopathy (DR), b) Age related macular degeneration (AMD) and matched healthy controls (HC).
  • To compare Bulbicam and the Standard Method on measurements of Visual Field and Pupil
  • To contribute to the establishment of normal range for DR and AMD patients with different degree in the disease development related to the Bulbicam tests.
  • To contribute to the establishment of normal range for a normal population without eye-disease related to the Bulbicam tests. Study population The study consists of the following three study populations: 1) Patients suffering from DR of both genders above 18 years of age with different disease degree; 2) Patients suffering from AMD of both genders above 18 years of age with different disease degree; 3) Gender- and age-matched HC without any eye diseases.

Study procedure Participants, who fulfil the inclusion criteria; do not meet any of the exclusion criteria and willing to give informed consent to participate will receive an appointment for starting the study. The Bulbicam examination will be performed twice a day with a rest period of one hour between each registration. This procedure will be repeated the following two days. All demographic data, social factors and history of disease will be recorded at screening. Additionally, the quality of life (QoL) questionnaires EQ-5D-5L developed by EuroQol will be recorded initially as individual baseline values.

The Common Terminology Criteria for Adverse Events (CTCAE) version 4.0 will be used for measuring and classifying the tolerability and toxicity at the end of each day of investigation.

Aim

  • To investigate repeatability and stability of the six OTH-related Bulbicam tests in patients suffering from a) Diabetic retinopathy (DR), b) Age related macular degeneration (AMD) and matched healthy controls (HC).
  • To compare Bulbicam and the Standard Method on measurements of Visual Field and Pupil
  • To contribute to the establishment of normal range for DR and AMD patients with different degree in the disease development related to the Bulbicam tests.
  • To contribute to the establishment of normal range for a normal population without eye-disease related to the Bulbicam tests. Study population The study consists of the following three study populations: 1) Patients suffering from DR of both genders above 18 years of age with different disease degree; 2) Patients suffering from AMD of both genders above 18 years of age with different disease degree; 3) Gender- and age-matched HC without any eye diseases.

Trial equipment Bulbicam will be used in the study and the following six tests will be performed at each investigation: "Neurofield 64", "Ptosis", "Dynamic Acuity", "Dynamic Contrast ", "Dark Adaptation" and "Pupil RAPD". The Standard Method will be used initially for measurements of "Neurofield64", "Visual Field" and "pupil".

Design

The study will be performed as a controlled, open, and non-randomized, stratified observational multicenter study. The stratification factors are the pathology of DR and AMD and the degree of disease. Within each of the four strata, healthy matched controls related to gender- and age (1:1) will be included. The degree of DR is defined as follows:

入选标准

  • Consists of patients diagnosed with either DR or AMD of both gender; passed the age of 18 years without any other eye disease; suffering from other know serious disease.
  • but have a health situation in accordance with expectations related to the age.
  • Gender- and age-matched controls to patients in study population 1 or 2; passed the age of 18 years without any eye diseases; not suffering from other know serious disease and have a health situation in accordance with expectations related to the age.

排除标准

  • Other visual disturbances and blindness
  • Posterior Chamber Intra Ocular Lens (PCIOL)
  • Physical or psychiatric disease, which may disturb the measuring procedure
  • Patients who are not able to perform eye movements, so no full paresis of any ocular muscles.
  • Patients whose visual acuity is less more than 1 logMAR in any eye, as these will not be able to focus on the test stimuli.
  • Patients whose visible part of the eye is abnormal, such as subconjunctival hemorrhages or deformed pupils.
  • Patients whose pupils are not able to respond normally to dilation or contraction due to damaged nerves, mechanical damage of the pupil etc.
  • Participating in another clinical trial with pharmaceuticals the last six weeks before start of this trial treatment.
  • With known alcoholic and drug dependency
  • Not able to understand information.
  • Not willing to give written consent to participate in the study.
