OCT in microtropia

The aim of this study was to assess whether OCT could be useful in detecting and documenting fixation in children with microtropia. The study used spectral domain OCT (Cirrus) in 15 patients (10 female, five male) and 10 control eyes....

25 years of OCT

David Huang first described optical coherence tomography (OCT) in 1991, in his seminal paper on the subject in Science. This method developed the work of others on ophthalmic interferometry, which essentially showed that measuring reflected light could be used to...

Essentials of OCT in Ocular Disease

Sir Isaac Newton was the first to establish the technique of low coherence white light interferometry. Following on from this, the principle of laser interferometry as an imaging modality for retina was applied by David Huang and his associates in...

OCT use with macular retinoblastoma

The authors explore the use of portable hand-held spectral domain OCT (SD-OCT) in three eyes of three infants and young children with macular retinoblastoma. All were treated with chemotherapy and all had SD-OCT before and after treatment. The children were...

Handbook of Retinal OCT

This is not a large colour atlas for optical coherence tomography (OCT) with comprehensive reference lists offering an in-depth description of this popular technology, but an up-to-date pocket or handbag-sized, soft-backed textbook that is likely to become a well-thumbed primer...

OCT imaging of occluded puncta

This is a description of the use of enhanced depth optical coherence tomography (OCT) to see whether a patent ampulla or canaliculus is detectable in patients with absent or occluded puncta. Nine occluded puncta of six patients with epiphora were...

OCT in peripheral corneal thinning

This small retrospective study used high resolution optical coherence tomography (OCT) Heidelberg Spectralis to identify features which could determine the underlying aetiology of peripheral corneal thinning. Ten patients were included; five with diagnoses of degenerative peripheral thinning; Terrien’s marginal degeneration...

Extraocular muscle OCT

The goal was to evaluate the use of the Heidelberg anterior segment optical coherence tomography (AS-OCT) to image extraocular rectus muscle insertions and to expand the use of the AS-OCT to also image vertical rectus muscles. The authors evaluated inter...

OCT angiography metrics in children

This prospective study aimed to quantify the vessel density of both the macular and optic nerve and foveal avascular zone (FAZ) values in 92 normal eyes of 92 children (42 boys, 50 girls) aged 13.4 ±2.65 years (seven to 18)....

Amblyopia OCT results

The authors compared the macular and peripapillary retinal nerve fibre layer (RNFL) thicknesses of amblyopic and fellow eyes using Stratus optical coherence tomography (OCT) to reveal any differences. They sought to determine the anatomical differences between these subtypes of strabismic...

OCT in proliferative diabetic retinopathy

This report set out to describe the anatomical relationships between retinal neovascular complexes (NVC), the posterior vitreous, and the vitreoretinal interface in patients with proliferative diabetic retinopathy using spectral domain OCT. The following was recorded for each NVC 1) posterior...

Comparison of SS-OCT and SD-OCT in polypoidal choroidal vasculopathy

Swept source OCT (SS-OCT) is known to have a longer wavelength than spectral domain OCT (SD-OCT), allowing deeper penetration into retinal and choroidal layers. The aim of this study was to investigate whether SS-OCT is superior to SD-OCT in imaging...
