Applications of corneal topography and tomography: a review [PDF]
Clinical & Experimental Ophthalmology, 2018 AbstractCorneal imaging is essential for diagnosing and management of a wide variety of ocular diseases. Corneal topography is used to characterize the shape of the cornea, specifically, the anterior surface of the cornea. Most corneal topographical systems are based on Placido disc that analyse rings that are reflected off the corneal surface.

Enhancement of Corneal Visibility in Optical Coherence Tomography Images with Corneal Opacification
Translational Vision Science & Technology, 2016 To establish and to rank the performance of a corneal adaptive compensation (CAC) algorithm in enhancing corneal images with scars acquired from three commercially available anterior segment optical coherence tomography (ASOCT) devices.Horizontal B-scans of the cornea were acquired from 10 patients using three ASOCT devices (Spectralis, RTVue, and ...

Corneal tomography in osteogenesis imperfecta [PDF]
, 2020 Osteogenesis Imperfecta (OI) is a rare genetic disorder with musculoskeletal manifestations and some ocular features, such as the presence of blue sclerae, corneal thinning, altered corneal biomechanics, and rare reports of keratoconus (KC). Corneal tomography is essential for KC screening and a BAD_D score over 1,6 and 2,6 is highly sensitive and ...

Advanced Surface Ablation in Mild (Fruste) Keratoconus: A Case Report
Ophthalmology and Therapy, 2020 Corneal ectasia is a complication of refractive surgery, and keratoconus is a contraindication to this type of procedure. Surface ablation may be an option for selected cases of mild keratoconus, with patient education being fundamental to this treatment
