Clinical Relevance: Isotretinoin has been the best treatment option for moderate and severe acne vulgaris since the 1980s. Some studies have shown evidence of subclinical anterior segment involvement of the eye in patients treated with isotretinoin.
Background: This study aimed to evaluate lens clarity with the densitometry software of Scheimpflug tomography in patients treated with isotretinoin and to compare with healthy control subjects.
Objectives: This study aimed to evaluate the effect of using an inferior or superior conjunctival autograft in primary pterygium surgery on the postoperative ocular surface.
Materials And Methods: Forty eyes of 40 patients who underwent pterygium surgery with autograft were included in the study. Cytological cell counts were performed on samples taken from the bulbar conjunctiva by impression cytology before and 1 year after the operation.
Purpose: The aim of the study is to evaluate the effect of limbal autograft location on corneal astigmatism in inferior and superior conjunctival autografted pterygium surgery.
Methods: Patients were divided into 2 groups as diagnosed with primary pterygium and planned to receive surgical treatment. Pterygium surgery was performed on 25 patients with superior and 25 patients with inferior limbal autograft who have similar epidemiologic features.
Objectives: This was an assessment of one-snip punctoplasty outcomes in patients for whom adjunctive punctal re-dilatation was performed in-office for early postoperative cicatricial changes.
Methods: A retrospective analysis was conducted of patients who underwent one-snip punctoplasty between March 2019 and February 2020 due to acquired punctal stenosis. Patients were followed up on the first, third, and seventh postoperative day, then weekly for the remainder of the first month, every 2 weeks over the next month, and then monthly.

Significance: Digital device usage among children has increased significantly in recent years. Prolonged screen exposure can have adverse effects on the eye, especially on the ocular surface.
Purpose: We aimed to evaluate the duration of screen exposure and its effect on the ocular surface in healthy children aged 10 to 18 years.
Purpose: To evaluate the prevalence of the obstruction of lacrimal drainage system (LDS) in patients with pseudoexfoliation (PXF) syndrome.
Materials And Methods: This cross-sectional study included 152 eyes of 76 consecutive patients with bilateral PXF syndrome and 170 eyes of 85 age and gender-matched controls. The LDS evaluation was performed based on dye disappearance test, slit-lamp examination, diagnostic probing, and irrigation test.
Purpose: To investigate the pathophysiology of punctal stenosis based on histopathological features, and to assess the correlation between histopathological findings and treatment outcomes in primary punctal stenosis.
Methods: A total of 43 eyes of 34 consecutive patients with primary punctal stenosis were included in this prospective study. Punctum specimens obtained by rectangular three-snip punctoplasty (TSP) were examined based on the multilayered structure of the epithelium and subepithelial histopathology.

Purpose: We investigated corneal endothelial morphology and corneal densitometry in smokers and compared our results with findings observed in non-smokers.
Materials And Methods: This cross-sectional observational study included 100 participants (50 smokers, 50 non-smokers) aged 18-80 years in whom corneal endothelial morphology was analysed using a non-contact Tomey EM-4000 specular microscope (Tomey Corporation, Japan). The Pentacam HR system was used to measure corneal densitometry spatially in three concentric zones (from the centre to the periphery) and at three different corneal depths (from the anterior to the posterior aspects).
Purpose: The aim of this study was to evaluate the potential changes in choroidal vasculature in nodulocystic acne patients under isotretinoin treatment by using choroidal thickness (CT), choroidal vascularity index (CVI), and choriocapillaris (CC) flow area.
Materials And Methods: This prospective study included nodulocystic acne patients under isotretinoin treatment and healthy controls. All patients underwent enhanced depth imaging-optical coherence tomography (EDI-OCT) imaging to assess the subfoveal CT and submacular CVI, and optical coherence tomography angiography (OCTA) imaging to evaluate the CC flow area.
Purpose: The purpose of this study was to evaluate the association between dry eye disease and patients with newly diagnosed obsessive-compulsive disorder (OCD).
Methods: Thirty treatment-naive patients with OCD and 30 healthy controls were included in this prospective study. The Ocular Surface Disease Index, tear breakup time, Schirmer I test, corneal and conjunctival staining grade (Oxford scale), and neutrophil-to-leucocyte ratio values were obtained for all participants.
Objectives: To investigate the prevalence of strabismus in families of a proband with accommodative, partial accommodative, or infantile esotropia, and to evaluate the mode of inheritance and the role of consanguineous marriages in this prevalence.
Materials And Methods: Families of probands with comitant strabismus were invited to participate in the study. The family members of 139 subjects with accommodative, 55 with partial accommodative, and 21 with infantile esotropia agreed to participate.
Purpose: To assess the effect of hemodialysis on retinal and choroidal thicknesses using spectral-domain optical coherence tomography (SD-OCT).
Methods: In this prospective interventional study, 25 hemodialysis patients (17 male, 8 female) were enrolled. All participants underwent high-speed, high-resolution SD-OCT (λ=840 mm; 26.
Aim: To assess choroidal thickness in patients with severe obstructive sleep apnea syndrome (OSAS) and compare them with healthy controls, using spectral domain optical coherence tomography (OCT).
Methods: In this observational, cross-sectional study, choroidal thicknesses of 23 newly severe OSAS patients and 23 body mass index- age- and sex-matched healthy subjects were measured using a high-speed, high-resolution frequency domain-OCT device (λ=840 nm, 26000 A-scans/s, 5 µm axial resolution). All patients underwent a complete ophthalmic examination before the measurements.
