Update on Dry Eye Disease Treatment: Evidence From Randomized Controlled Trials.

Although the ultimate goal of dry eye disease (DED) management is to restore the ocular surface and tear film homeostasis and address any accompanying symptoms, addressing this is not an easy task. Despite the wide range of current treatment modalities targeting multiple aspects of DED, the available DED management literature is quite heterogeneous, rendering evaluation or comparison of treatment outcomes hard or almost impossible. There is still a shortage of well-designed, large-scale, nonsponsored, randomized, controlled trials (RCTs) evaluating long-term safety and efficacy of many targeted therapies individually or used in combination, in the treatment of identified subgroups of patients with DED.

Long-term visual, refractive, tomographic and aberrometric outcomes of corneal collagen crosslinking (CXL) with or without hypoosmolar riboflavin solution in the treatment of progressive keratoconus patients with thin corneas.

Purpose: To evaluate the long-term visual, refractive, tomographic, and aberrometric outcomes of corneal collagen crosslinking (CXL) with or without hypoosmolar riboflavin solution in the treatment of progressive keratoconus patients with thin corneas.

Methods: Charts of consecutive progressive keratoconus patients with thinnest corneal thickness less than 470 µm who underwent corneal collagen CXL with or without hypoosmolar riboflavin solution and using a standardized protocol for treatment and examinations were analyzed retrospectively. The indication for hypoosmolar riboflavin use was a central corneal thickness less than 400 µm as measured by ultrasound pachymetry after epithelial debridement and before exposure to ultraviolet A (UVA) light.

Diplopia After Migraine Surgery.

A 46-year-old man with refractory migraine headache was treated with decompressive migraine surgery of the supraorbital and supratrochlear nerves. Postoperatively, he reported diplopia that got better on left head tilt. After ophthalmological examination, a diagnosis of right superior oblique palsy was made.

Ocular Findings of Pediatric Dry Eye Related to Graft-Versus-Host Disease.

Objectives: To evaluate the frequency and findings of dry eye associated with ocular graft-versus-host disease (GVHD) in pediatric hematopoietic stem cell transplantation (HSCT) patients.

Materials And Methods: Retrospectively the records of pediatric patients with ocular GVHD were evaluated and ophthalmologic examination findings as well as Schirmer test results, tear film break-up time, and corneal staining grades were recorded. In severe dry eye patients topical cyclosporine-A was prescribed and the results were evaluated.

The Correlation of Inflammation and Microvascular Changes with Diabetic Retinal Neurodegeneration.

: To evaluate the effect of aqueous flare intensity as a measurement of inflammation and microvascular changes on retinal neurodegeneration in diabetic eyes.: In cross-sectional study diabetic patients were assigned into 2 groups according to the presence of retinopathy: patients with nonproliferative diabetic retinopathy (group 1) and diabetic patients without clinically overt retinopathy (group 2). As a control group (group 3), age-matched healthy controls were included in the study.

Cytomegalovirus Endotheliitis After Penetrating Keratoplasty.

Cytomegalovirus (CMV)-related corneal endotheliitis is an inflammation of the corneal endothelium caused by CMV. It may occur de novo or after ocular surgery in otherwise healthy individuals. In patients who have undergone keratoplasty, the differential diagnosis of viral endotheliitis and immune-related graft rejection is challenging due to the similar clinical findings.

Direct and transsynaptic retrograde degeneration and optic nerve head microvascular changes in patients with hemianopia.

Purpose: To investigate optic nerve head (ONH) microvascular changes secondary to transsynaptic retrograde degeneration (TRD), comperatively with direct retrograde degeneration and healthy controls.

Methods: Patients with hemianopia due to intracranial lesion included in the study. Intracranial lesion was categorized by location: postgeniculate (causing TRD), chiasmal (causing direct retrograde degeneration).

Pediatric versus Adult Corneal Collagen Crosslinking: Long-term Visual, Refractive, Tomographic and Aberrometric Outcomes.

Purpose: To comparatively evaluate the long-term visual, refractive, topographic and aberrometric outcomes of conventional corneal collagen crosslinking (CXL) in the management of pediatric versus adult progressive keratoconus patients.

Materials And Methods: Retrospective, cross-sectional review of consecutive progressive keratoconus cases of corneal standard CXL using a standardized protocol for treatment and examinations was performed. Best spectacle-corrected distance visual acuity (CDVA), manifest refraction, slit lamp biomicroscopy, corneal tomography, corneal aberrometry and endothelial cell counts were evaluated at baseline and yearly at all postoperative follow-up examinations after month-12.

Role of Inflammation in Retinal Microcirculation in Diabetic Eyes: Correlation between Aqueous Flare and Microvascular Findings.

Purpose: To investigate the correlation between aqueous flare and macular microvascular status assessed by optic coherence tomography angiography (OCTA) in diabetes mellitus.

Methods: A cross-sectional study was conducted on 52 diabetic patients with nonproliferative retinopathy, 44 diabetic patients without retinopathy, and 20 nondiabetic age-matched controls. Spectral domain OCT, OCTA, and laser flare-cell meter were performed.

Ocular vascular changes during pregnancy: an optical coherence tomography angiography study.

Background: Pregnancy is a period presenting with many physiological adaptation mechanisms. One of the structures in which these mechanisms are observed is ocular tissues. The cornea, lacrimal and meibomian glands, and chorioretinal complex are all among the structures affected by changes during pregnancy.
