Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The pupilometer determines the alteration of the pupil diameter after a defined light stimulus. In this study data is collected from pupilometer measurements of patients with an acute cerebral disease. The measurements take place during daily neurological routine examinations. The values are compared to outcomes resulting from pupilometer measurements done on patients having not an acute cerebral disease (e.g. cerebral aneurysm without symptoms). The study aims to establish the not invasive method of pupillometry for detecting neurological degradations early.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The pupilometer determines the alteration of the pupil diameter after a defined light stimulus providing information of the autonomic nerve system. The result collecting from pupillometry is objective and more precise than the subjective-visual evaluation of the pupil and its reactivity.

In this observational study data is collected from pupilometer measurements of patients with an acute cerebral disease. The measurements take place during neurological routine examinations. The first measurement is done during the initial diagnosing examination, followed by daily measurements and ending with measurements after 3 and 6 month upon hospital discharge. The values are compared to standard values resulting from pupilometer measurements done on patients having non-acute cerebral disease (e.g. cerebral aneurysm without symptoms). The study aims to establish the not invasive method of pupillometry for detecting neurological degradations early.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Control group

The control group implies patients with non-acute cerebral disease (e.g. cerebral aneurysm without symptoms). The pupilometer data are once collected during ambulant routine examination. The patients do not undergo any further study related examinations.

Pupilometer

Intervention Type DEVICE

Device to measure change in pupil diameter due to a defined light stimulus.

Treatment group

The treatment group implies patients with an acute cerebral disease ensured by CT, MRI or spinal tap. Pupillometry measurements are done during neurological routine examinations. Generally, during the initial diagnosis examination, followed by daily routine measurements and after 3 and 6 month upon hospital discharge.
