Methods: This prospective pilot study included 30 eyes of 30 patients who received oral isotretinoin treatment due to acne. Each patient underwent a general ophthalmological examination.
Objectives: To investigate in detail the exact relationship between Pseudomyopia, also termed accommodative spasm, and psychiatric disorders.
Methods: Twenty-one young people between the ages of 12-18 who were diagnosed with pseudomyopia between March 2019 and July 2020 in the ophthalmology eye clinic of a university hospital, Turkey were included in the study. A difference of at least 2.

Background Methylphenidate (MPH) hydrochloride is used as a first-line treatment for attention deficit hyperactivity disorder (ADHD). However, there is concern that this treatment may be associated with increased risk of refractive disorder. The aim of this study was to investigate the effect of MPH therapy on myopic shifts in refraction in children diagnosed with ADHD.

Methods: The study included a total of 30 patients with SS and dry eye symptoms and a control group of 50 age- and gender-matched healthy subjects. The dryness parameters of all the participants were evaluated.
Purpose: To investigate the effect of oral isotretinoin use on refractive error, axial length, and anteroposterior segment parameters.
Materials And Methods: In this prospective study, 50 eyes of 50 patients using isotretinoin with a diagnosis of acne vulgaris and 50 eyes of 50 healthy control subjects were included. After detailed biomicroscopy, measurements were taken of axial length, lens thickness, central corneal thickness, anterior chamber depth, central retinal thickness, and subfoveal choroidal thickness.

Purpose: To evaluate the dry eye disase and meibomian gland dysfunction with meibography of Seborrheic Dermatit patients.
Methods: A hundred-ten of 50 patients with Seborrheic Dermatitis (group 1) and 100 eyes of 50 healthy individuals (group 2) were enrolled in this prospective study. All subjects were performed a comprehensive ophthalmic examination including lid margin alterations and meibomian gland obstruction assessment, Ocular Surface Disease Index assessment, tear film break-up time test, corneal and conjunctival fluorescein staining assessment, Schirmer test.
Purpose: To report the measurements of central corneal thickness (CCT) in uveitic eyes with Behçet disease (BD) and compare it with age- and sex-matched healthy controls.
Materials And Methods: This study included 69 eyes with ocular BD with no history of corneal disease, glaucoma, or ocular surgery and 50 eyes of healthy controls. Eyes with ocular BD were subdivided into active and inactive groups.
Purpose: To report a combined cilioretinal artery and partial central retinal vein occlusion shortly after delivery in a twin-pregnant woman.
Methods: A 25-year-old woman presented to our clinic with the complaint of blurred vision in the right eye 1 week after delivery. She underwent detailed ophthalmic and systemic investigations.
