Automatic Quantitative Assessment of Lens Opacities Using Two Anterior Segment Imaging Techniques: Correlation with Functional and Surgical Metrics

Diagnostics, 2022
The purpose of this study is to quantitatively assess lens opacity, using a swept-source optical coherence tomography (SS-OCT) device for anterior segment assessment, and establish the correlation with Scheimpflug imaging, corrected distance visual ...

Keratoconus Detection Based on a Single Scheimpflug Image

Translational Vision Science & Technology, 2020
To introduce a new approach for keratoconus detection based on corneal microstructure observed in vivo derived from a single Scheimpflug image.Scheimpflug single-image snapshots from 25 control subjects and 25 keratoconus eyes were analyzed; from each group, five subjects were randomly selected to provide out-of-sample data.

Objective Scheimpflug imaging of the healing cascade and repair process of striate keratopathy with the concept of optical blooming

Indian Journal of Ophthalmology. Case Reports, 2022
To our knowledge, assessment of striate keratopathy (SK) is subjectively done with slit-lamp bio-microscopic examination, which is the most common practice.

Scheimpflug imaging in anterior megalophthalmos

Indian Journal of Ophthalmology, 2013
We report an anterior megalophthalmos case with decreased corneal thickness and show the findings using Scheimpflug imaging. A 25-year-old male was diagnosed with anterior megalophthalmos. In both eyes, enlarged corneal length was measured. Beside a comparatively good visual acuity, a thin but clear cornea, a fairly deep anterior chamber, and central ...

Role of epithelial mapping in the differentiation between early keratoconus and high regular astigmatism using spectral-domain optical coherence tomography

Journal of the Egyptian Ophthalmological Society, 2023
Pur6pose To detect epithelial thickness-based diagnostic variables to detect early keratoconus (KC) and differentiate cases of early KC from high regular astigmatism, especially if abnormal topographic changes are present.

Role of scheimpflug imaging in the diagnosis and management of keratitis caused by caterpillar seta

Oman Journal of Ophthalmology, 2010
A 16-year-old boy presented with a history of an accidental hit to the left eye by a butterfly (Lepidoptera). One seta fragment was found to be embedded into the cornea and inflammation secondary to penetration of caterpillar seta was seen around the ...
