Optic Disc Swelling | Antiacne Medications Pseudotumor Cerebri

Optic Disc Swelling research study

What is the primary objective of this study?

The exact incidence of optic disc swelling and idiopathic intracranial hypertension in patients using antiacne medication is not known so far. The investigators hypothesize that swelling of retinal nerve fibre layer measured by optical coherence tomography is more frequent then assumed so far.

Who is eligible to participate?

Inclusion Criteria: - Antiacne medication treatment indicated by dermatologist - age > 18 years - contraception if indicated Exclusion Criteria: - age < 18 years

Which medical condition, disease, disorder, syndrome, illness, or injury is researched?

Optic Disc Swelling

Study Interventions

Interventions can include giving participants drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available or noninvasive approaches such as surveys, education, and interviews.

Other:Retinal nerve fibre layer measurementMeasurement of retinal nerve fibre layer thickness using optic coherence tomography.

Study Arms

Research studies and clinical trials typically have two or more research arms. An arm is a group of people who receive the same treatment in the study.
