Purpose: To evaluate complete blood count (CBC)-derived inflammatory indices in central retinal artery occlusion (CRAO).

Methods: A total of 42 patients with CRAO (CRAO group) and 42 age- and sex-matched subjects without CRAO (Control group) were included. CBC parameters including red cell distribution width (RDW) levels were assayed.

Evaluation of systemic immune-inflammation index level as a novel marker for severity of noninfectious uveitis.

Purpose: To evaluate the association of systemic immune-inflammation index (SII) levels, neutrophil/lymphocyte ratio (NLR), and platelet/lymphocyte ratio (PLR) with severity of noninfectious uveitis.

Methods: This retrospective study included 46 patients with noninfectious uveitis (uveitis group) and 46 age- and sex-matched healthy subjects (control group). The demographic and ocular findings, localization, and activity of uveitis were recorded at the time of onset evaluation.

Corneal biomechanical parameters in systemic autoimmune diseases.

Clinical Relevance: The relationship between the cornea and systemic autoimmune diseases has been demonstrated in prior studies. Corneal Visualisation Scheimpflug Technology (Corvis ST) provides a specific and detailed assessment of corneal biomechanical features, such as stiffness and elasticity.

Background: This study aims to evaluate corneal biomechanical changes in patients with systemic autoimmune diseases using Corvis ST.

Efficacy of two silicone-hydrogel bandage contact lenses after corneal crosslinking.

Silicone-hydrogel (SiH) contact lenses are frequently used as a bandage after anterior segment surgical procedures. Several types of lenses may exhibit clinical performances with different characteristics. This study aims to evaluate the efficacy of two SiH contact lenses following corneal crosslinking (CXL).

Assessment of platelet-to-lymphocyte ratio in patients with retinal vein occlusion.

Purpose: To investigate platelet-to-lymphocyte ratio (PLR) in retinal vein occlusion (RVO) patients.

Methods: In this study, we retrospectively reviewed data of 32 patients with RVO (RVO group) and 32 age- and sex-matched participants without RVO (control group) between January 2017 and March 2019. The PLR was determined by dividing the platelet count by the lymphocyte count.

Increased Systemic Immune-Inflammation Index Levels in Patients with Dry Eye Disease.

Purpose: To evaluate the systemic immune-inflammation index (SII) levels, neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio (PLR) in patients with dry eye disease (DED) and to compare with control subjects.

Methods: This prospective study included 47 DED patients and 47 age- and sex-matched healthy controls. Ophthalmological examination, diagnostic DED tests, and routine complete blood cell count parameters were analyzed.

Schnyder Corneal Dystrophy: A Rare Case Report.

Introduction: Schnyder corneal dystrophy (SCD) is a rare, autosomal dominant, anterior stromal dystrophy described as progressive bilateral corneal opacification due to abnormal accumulation of cholesterol and phospholipids in the cornea. The clinical signs can change as the patient ages. SCD with different presentations may actually be misdiagnosed.

Evaluation of microvascular changes in optic disc and retina by optical coherence tomography angiography during Valsalva maneuver.

Purpose: Optical coherence tomography angiography (OCTA) is an increasingly widespread imaging tool that allows the visualization of the microvascular structures of the eye. It should be kept in mind in clinical practice, Valsalva maneuver (VM) may have an effect on OCTA findings. We aimed to evaluate the effect of VM on the optic nerve and retinal blood flow parameters measured by OCTA.

Traumatic superior orbital fissure syndrome.

Traumatic superior orbital fissure syndrome is a rare complication that occurs in association with craniofacial trauma. In the present case, there were no associated orbital fractures or other lesions to explain. We present a-16-year-old patient with total ophthalmoplegia, ptosis, and anesthesia of the upper eyelid and forehead 6 hours after a reported trauma to the left eye.
