Comparison of bleb grading and IOPs

The purpose of this study was to compare a novel anterior segment optical coherence tomography (AS-OCT) bleb grading system with a clinical bleb grading system (Moorfields) and both with intraocular pressure (IOP) levels following trabeculectomy surgery. The authors developed a...

Retinopathy of prematurity

This review article describes the pathophysiology of retinopathy of prematurity (ROP). The authors start by introducing the condition and its incidence. There is extensive information on the pathophysiology mechanisms involved in the condition to include normal and pathological retinal development....

Optical coherence tomography – reinventing the eye examination

It has been 25 years since Huang et al. presented the first optical coherence tomography (OCT) images in Science [1]. With vast improvements in OCT technology over the years, it is now possible to acquire high-resolution cross-sectional images of the...

Hot debates in medical retina and imaging: Perspectives from the Controversies in Ophthalmology 2020 virtual conference

Controversies in medical retina and imaging were debated during the Controversies in Ophthalmology 2020 virtual conference held during two mid-day scientific sessions on 27 and 28 March 2020. The author recounts key perspectives and presents viewpoint recommendations from the Vision...

Sense Medical and Canon: Getting ready for the OCT Pathway in Diabetic Eye Screening Surveillance Pathway webinar

Are you ready for the OCT pathway in DESP? OCT is set to be integrated into the English National Diabetic Eye Screening Surveillance Pathway, significantly enhancing the management of patients with mild diabetic maculopathy. This advancement allows patients to remain within a surveillance pathway overseen by retinal screening rather than being immediately referred to the Hospital Eye Service (HES). The webinar will be hosted by Professor Tunde Peto and Mrs Samantha Mann and will discuss the new OCT pathway, how OCT will change diabetic screening, how to interpret OCT images and how programmes can get ready for the change. Starts at 6pm UK time for 90 minutes

Diagnostic accuracy of enhanced depth imaging OCT in children

The authors present the findings of a retrospective cross-sectional case series. Cases were identified using a treatment register having been evaluated in a set one-year period. Two ophthalmologists acted as masked image examiners for enhanced depth imaging optical coherence tomography...

Accuracy of AS-OCT muscle insertion measurements

Anterior segment - optical coherence tomography (AS-OCT) is a non-contact imaging method that can provide accurate measures of extraocular muscles to limbus insertion distances. The authors evaluated the accuracy of AS-OCT for locating horizontal extraocular muscle insertions after strabismus surgery...

CSD-OCT detection of minimally visible retinoblastoma

This paper reports minimally visible tumour recurrence that was detectable on spectral domain OCT (SD-OCT) in a two-month-old infant who had a diagnosis of bilateral familial retinoblastoma. The infant was treated with IVC for six cycles with vincristine, etoposide and...

SD-OCT detection of minimally visible retinoblastoma

This paper reports minimally visible tumour recurrence that was detectable on spectral domain OCT (SD-OCT) in a two-month old infant who had a diagnosis of bilateral familial retinoblastoma. The infant was treated with IVC for six cycles with vincristine, etoposide...

OCT changes in chronic optic neuropathy

The authors evaluated optical coherence tomography (OCT) angiography in 10 patients who suffered various types of chronic optic neuropathies. Glaucoma is known to cause a decrease in peripapillary perfused capillary density on OCT angiography. However, other optic neuropathies have not...

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...

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...
