Purpose: To investigate the association of clinical findings and indocyanine green angiography (ICGA) score with inflammatory markers derived from complete blood count (CBC) parameters in patients with Vogt-Koyanagi-Harada (VKH) to determine the diagnostic and predictive role.
Methods: Demographic characteristics, presenting complaints, ocular findings, optical coherence tomography findings, ICGA scores and best corrected visual acuity were recorded in treatment-naive VKH patients at presentation. Patients were divided into two groups as acute stage and chronic recurrent stage.
Purpose: To evaluate the changes in peripapillary microvascularity in idiopathic intracranial hypertension (IIH) and optic disc drusen (ODD) patients, by comparing them with those in healthy individuals, via optical coherence tomography angiography (OCTA).
Methods: Sixty-two eyes of 33 patients with ODD, 58 eyes of 30 patients with IIH, and 70 eyes of 70 healthy people were imaged for 6 × 6-mm optic disc scans on a spectral-domain OCTA. Vascular densities in superficial capillary plexus (SCP), deep capillary plexus (DCP), and choriocapillaris (CC) of ODD, IIH, and healthy eyes were compared with a one-way analysis of variance.
A 42-year-old woman presented with bilateral proptosis, chemosis, leg pain, and vision loss. Orbital, chorioretinal, and multi-organ involvement of Erdheim-Chester disease, a rare non-Langerhans histiocytosis, with a negative BRAF mutation was diagnosed based on clinical, radiological, and pathological findings. Interferon-alpha-2a (IFNα-2a) was started, and her clinical condition improved.

Objectives: The aim of the study was to evaluate the effect of changes in the horizontal and vertical palpebral fissure dimensions on surgical success performed due to entropion and ectropion of the lower eyelid.
Methods: The present research was conducted as a retrospective and interventional case series who had undergone involutional lower eyelid malposition repair with a lateral tarsal strip (LTS) alone, LTS with a medial spindle, and LTS with the advancement of the lower eyelid retractors. The subjects' medical records, including demographic and clinic characteristics, pre-operative assessment of horizontal eyelid laxity, and surgical outcomes, were reviewed.
Background: To compare the changes in anterior chamber laser flare after phacoemulsification and intraocular lens implantation according to phaco parameters in eyes with and without pseudoexfoliation syndrome.
Methods: Patients (39 without pseudoexfoliation (PEX), 28 with pseudoexfoliation) who underwent the surgery with the same device (Centurion System, Alcon Laboratories, USA) and same experienced surgeon were divided according to the presence of PEX. Anterior chamber laser flare was assessed using a laser flare meter (Kowa-FM700, Kowa Company, Japan) by the same blinded researcher.
Objectives: This study evaluated anterior segment surgeries performed during the coronavirus 2019 (COVID-19) pandemic. Prevention of virus transmission is a critical consideration for surgeons, and includes assessment of etiology, the referral region, demographic characteristics, and the surgery to be performed.
Methods: The data of 144 patients who underwent anterior segment surgery between March 19, 2020 and June 1, 2020 were retrospectively reviewed.
Objectives: Gold weight implantation in the upper eyelid is a frequently performed treatment for paralytic lagophthalmos to prevent corneal exposure. A margin reflex distance of -1 and -2 (MRD1, MRD2), the palpebral fissure height (PFH), and the vertical lagophthalmos (LV) are 1-dimensional (1D) measurements used in follow-up. Because the exposure area is 2-dimensional (2D), this study was designed to investigate the results using both 1D and 2D analysis.

Methods: The patients who underwent unilateral MMCR (group1, = 25) and ELA (group2, = 25) were reviewed retrospectively. With the written algorithm, margin reflex distance-1 (MRD1), localization of the contour peak, and the percentage of overlapping curvatures (POC) of both upper eyelid curves were calculated.

Botulinum toxin A was injected transconjunctivally, just above the superior tarsal border of the upper eyelid in doses between 2-15 units according to an algorithm, depending on the amount of retraction.
