Incremental nature of anterior eye grading scales determined by objective image analysis

Contact Lens Ant Wcales ; J Allergy Clin Immunology ; These image analysis techniques have been used to try to determine how clinicians grade bulbar hyperaemia, with one study suggesting that the number of vessels and the gradign of the image occupied by vessels are more important than relative colouration 15 whereas another indicated both these factors were integral to grading. Image analysis of a particular feature may require the assessment of a number of characteristics to provide a more simplistic condition grade, comparable with although having better repeatability and sensitivity than subjective techniques.

A modern grading scale adapted for smartphone use. Clinical grading and the effects of scaling. Vistakon-Synoptik palpebral conjunctivitis images were analysed selecting the palpebral hyperaemia and the area with reflections separately to distinguish between scalfs and roughness. J Br Contact Lens Assoc ; Edge detection techniques are local rather than global in nature and examine the surrounding pixels to determine the presence of edges vessels or areas of staining.

A novel grading method for superficial punctate keratopathy magnitude and its correlation with corneal epithelial permeability. Open in a separate window. The app enables levels of severity to be compared side-by-side in 0. The average time taken to record anterior eye health was 6. Social media and SEO success. Communication at the heart of it all. Grading gradibg such as palpebral hyperaemia, palpebral roughness, and corneal staining is complex and there is a compromise between the simplicity scalds a single scale and the ability to fully describe and monitor changes in the feature.


Please review our privacy policy. Practitioners must record the grading scale used, and ideally standardise this within an individual practice or corporate groups.

Fight for Gradibg retinoblastoma Fight for Sight launches retinoblastoma research campaign. In order to improve and standardise anterior eye evaluations between practitioners, subjective grading scales were first popularised back in the mids. Clinical grading scales also offer practitioners the most effective way of monitoring the health of an eye wearing a contact lens.

This results in the lower end of the scale being more sensitive a smaller change between grades than the upper end of the scale. Therefore this study aimed to determine, by objective image analysis, whether commonly used clinical pictorial and photographic subjective grading scales are incremental in nature.

Highlighting the scaless with fluorescein would appear a more appropriate method for determining palpebral scalee as previously described, 25, 26 causing an increase in edges detected and a decrease in the fluorescein coverage, despite an apparent decrease in severity with the highest CCLRU scale grade.

Edge detection filled symbols and relative red colouration open symbols with grading scale images of palpebral hyperaemia. Am J Optom Physiol Opt ; The repeatability of discrete and continuous anterior segment grading scales.

Included in the improved version will be high definition images and compatibility with iPads as well as iPhones. Sign up for our free e-newsletters Get all the latest jobs and product news emailed to you every week Click here to register.


Practitioners often sfales this limitation by adopting half-point scales, or by assigning plus and minus symbols next to an integer scale.

To examine the incremental nature of the Annunziato, 29 Efron Millennium Edition9 and Vistakon-Synoptik 4 grading scales, the printed images of clcru hyperaemia, palpebral hyperaemia also referred to as papillary conjunctivitisand corneal staining extent were scanned at dpi stored in tagged image format TIFF and analysed. Tarsal conjunctival scalez of Asymptomatic soft contact lens wearers and non-wearers. Increments of scales used. A report can then be exported for practice records without collecting patient personal data.

Int Contact Lens Clinics ; Conclusions of this second study were that optometrists grade a diverse array of anterior eye conditions, the three ocular conditions that were found to be the most frequently graded were corneal staining, papillary conjunctivitis and conjunctival redness.

Finer scales have the advantage wcales being capable of recording clinical change more sensitively.

Incremental nature of anterior eye grading scales determined by objective image analysis

Both techniques were strongly correlated with increasing bulbar hyperaemia scale grades, although for higher grades the Annunziato and Vistakon-Synoptik scales rely on an increase in red colouration in isolation, rather than in combination with an increased number of blood vessels. The increments of the gradimg scales were best described by a quadratic rather than a linear function.

Variability of clinical researchers in contact lens research. Objective measurement of contact-lens induced conjunctival redness.
