Age-Related Changes in Corneal Epithelial Thickness Measured with an Ultrasound Pachymeter.

Background: There is increasing research on the aging process of the cornea and its effect on the corneal parameters measured objectively. Nevertheless, the association of corneal epithelial thickness (CET) with age has yet to be fully illustrated.

Purpose: We aimed to measure CET in healthy subjects to determine its age-related variation by using an ultrasound device.

Correlation between corneal thickness, keratometry, age, and differential pressure difference in healthy eyes.

To determine the use of differential pressure difference (DPD), in air-puff differential tonometry, as a potential biomechanical measure of the cornea and elucidate its relationship with the intraocular pressure (IOP), central corneal thickness, corneal curvature, and age. This study comprised 396 eyes from 198 patients and was conducted at Acibadem University, School of Medicine, Department of Ophthalmology, Istanbul, Turkey. The central corneal curvature and refraction of the eyes were measured using an Auto Kerato-Refractometer (KR-1; Topcon Corporation, Tokyo, Japan).

Potential role of Müller cells in the pathogenesis of macropsia associated with epiretinal membrane: a hypothesis revisited.

Pathophysiological explanations for metamorphopsia associated with retinal pathologies generally focus on photoreceptor organization disruption. However, the retinal microarchitecture is complicated, and we hypothesize that other retinal cells may also be involved. Metamorphopsia has been widely studied in eyes with epiretinal membranes and we revisit the idea that Müller cell displacement causes retinal macropsia.

Shallow Anterior Chamber in a Severe Case of Unilateral Acute Central Serous Retinal Detachment.

Background: Atypical serous chorioretinopathy can present with symptoms similar to those of other pachychoroid diseases; however, a proper differential diagnosis will prevent unnecessary intensive treatments. To this end, we report on the shallowness of anterior chamber and transitory anterior vitreous cells in a patient with atypical severe serous retinal detachment.

Case Presentation: A 42-year-old woman presented with unilateral visual loss accompanied by mild, vague eye pain for 4 days.
