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...
Choroidal thickness in ocular sarcoidosis by OCT measurement
This is the first study to evaluate the choroidal thickness in patients with ocular sarcoidosis during the quiescent phase using enhanced depth imaging optical coherence tomography (EDI-OCT) and comparing with normal subjects. Ocular sarcoidosis may affect the choroidal circulation (occlusive...
Fluorescein angiography and OCT in myopic CNV
Fluorescein angiography (FA) and spectral-domain optical coherence tomography (OCT) are the most common examinations used in the management of anti-VEGF therapy in choroidal neovascularisation (CNV). In comparison to FA, OCT provides a noninvasive evaluation of the macula. Myopic CNV are...
Visual fields and OCT in hydroxychloroquine retinopathy
It has been recommended that patients on hydroxychloroquine be monitored regularly for retinopathy. However, there has not been an agreement as to the best screening test for hydroxychloroquine toxicity, which may include visual fields (VF), fundus autofluorescence, spectral domain optical...
Spectral domain OCT vs. confocal scanning laser ophthalmoscope in measuring RNFL thickness
The aim of this prospective study was to compare the retinal nerve fibre layer thickness (RNFL) measurements obtained from the Cirrus optical coherence tomography (spectral domain OCT) with the Heidelberg Retinal Tomograph 3 (HRT3, confocal scanning laser ophthalmoscope). Eighty-eight normal...
Clinical course of vitreomacular adhesion managed by initial observation
The purpose of this study was to investigate the clinical course of patients with idiopathic vitreomacular adhesion (VMA) with a noncomparative case series of patients who had clinical symptoms and spectral-domain optical coherence tomography findings consistent with VMA. The VMA...
Scheimpflug vs. OCT in measuring corneal thickness
The authors report on the reproducibility and repeatability of corneal thickness measurements using three different Scheimpflug imaging cameras (Pentacam, Sirius and Galilei) and one Fourier-domain optical coherence tomography (OCT) system (RTvue-100). The rationale for this study is that corneal thickness...
Macular pigment and dark adaptation in older population with normal maculas
Macular pigment (MP) such as lutein, zeaxanthin and meso-zeaxanthin are highly concentrated in the fovea. They protect the retina from damage of ambient blue light via antioxidant properties. In older eyes with normal healthy retina, macular pigment optical density (MPOD)...
Optical coherence tomography angiography usability in measuring iris vasculature in strabismus surgery
The purpose of this study was to investigate the use of optical coherence tomography angiography (OCTA) as a screening tool for anterior segment ischemia (ASI) in strabismus surgery. Optical coherence tomography angiography measurements were taken in 18 subjects. Twelve were...Andy Biart joins Carleton Optical as Surgical Business Manager, South
Carleton are pleased to welcome Andy Biart to their surgical team.
Review of chalazion treatment
Even though chalazion is a common eyelid lesion, there is lack of consensus on a treatment algorithm. Conservative management includes lid hygiene and warm compresses and, in some cases, steroid ointments for two to three weeks. More invasive options for...
