Brief Summary:
The investigators aimed to evaluate the effect of oral contraceptive pills(OCP) on macula, retinal nerve fiber layer and choroid thickness by using Optical Coherence Tomography (OCT). The present clinical study is the first research reported in the literature which is investigating the posterior ocular segment changes in women using OCP by using OCT.

Condition or disease Intervention/treatment Phase
Adverse Effect of Oral Contraceptives, Subsequent Encounter Drug: oral contraceptive pills Phase 4
