The Influence of Topical Cyclopentolate Instillation on Peripapillary and Macular Microvasculature Measured by Optical Coherence Tomography Angiography in Healthy Individuals.

Purpose: To investigate the influence of topical cyclopentolate 1%, as an anti-muscarinic mydriatic agent, on the peripapillary and macular microvasculature by optical coherence tomography angiography (OCT-A) in healthy adults.

Methods: A total of 41 healthy adults without any systemic or ocular disease were enrolled for this prospective consecutive study. All patients underwent OCT-A measurements (OptoVue Inc.

The diagnostic value of systemic immune-inflammation index in diabetic macular oedema.

Clinical Relevance: Diabetic macular oedema (DME) is a significant cause of visual impairment and inflammation plays an important role in its pathophysiology.

Background: This study evaluates the diagnostic value of systemic immune-inflammation index (SII) in the occurrence of DME in patients with non-proliferative diabetic retinopathy.

Methods: In this prospective study, the SII was applied to 150 consecutive patients with non-proliferative diabetic retinopathy.

Investigation of the Retinal and Optic Disc Microvascularization in Polycystic Ovary Syndrome: An Optical Coherence Tomography Angiography Study.

Purpose: To investigate retinal and optic disc microvascular alterations using optical coherence tomography angiography (OCTA) in women with polycystic ovary syndrome (PCOS).

Methods: Forty-six eyes of 23 patients with PCOS (PCOS group), and 50 eyes of 25 sex and age-matched healthy controls (control group) were included in this cross-sectional study. Foveal retinal thickness, peripapillary retinal nerve fiber layer (RNFL) thickness, vessel density in different sections of the retina and optic disc were analyzed by OCTA.

Assessment of Red Cell Distribution Width, Platelet/lymphocyte Ratio, Systemic Immune-inflammation Index, and Neutrophil/lymphocyte Ratio Values in Patients with Central Retinal Artery Occlusion.

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.
