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.
Measurement of retinal nerve fibre layer using optical coherence tomography over a period of 6 to 9 months depending on exact antiacne medication.

| Retinal nerve fibre layer | Measurement of retinal nerve fibre layer using optical coherence tomography. Changes over 10 micrometers are considered to be clinically relevant. The Term "retinal nerve fibre layer" describes an automated standardized optical coherence tomography measurement program measuring the sectorial thickness of the peripapillar retinal nerve fibre layer. There exists no other term for that. | 9 months |
