An area of approximately 90 pixels about 6. Nowadays, many practitioners record clinical information electronically by entering data into defined fields within computer-based clinical management software programs — a practice that in effect prompts practitioners to capture all relevant aspects of the presenting signs and symptoms.

The objective grading of ocular redness gradign judgement of both the hue and vessel size, relative to the area under question. Palpebral hyperaemia scale images were well described by colour extraction techniques.

Southwest Independent Institutional Review Board, They allow for an accurate means of detecting change that can occur during lens use and provide the practitioner with the necessary information to intervene to minimise the risk of a chronic adverse reaction to the contact lens. This article has been cited by other articles in PMC.

Am J Ophthalmol ; Edge detection and colour extraction image analysis techniques are highly repeatable and offer the potential for more repeatable and sensitive grading than using printed subjective grading cclruu. The BHVI photographic scales have been criticised for the lack of perfect homogeneity between images representing the same condition, either in terms of different illumination conditions or variability of size of the area under display.


Highlighting the papillae with fluorescein would appear a more appropriate method for determining palpebral roughness 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.

Annunziato and Efron pictorial, and CCLRU and Vistakon-Synoptik photographic grades of bulbar hyperaemia, palpebral gradig roughness, and corneal staining were analysed. The latter consists of a series of artist illustrated graeing of 16 different conditions, while the former comprises gfading of 6 conditions, two of which are presented in multiple manifestations. Invest Ophthalmol Vis Sci ; Therefore an epithelial scratch, punctate staining, and confluent ulceration could all have similar intensity of green colouration and edge detected area.

The average time taken to record anterior eye health was 6. Optom Vis Sci ; Assessment of conjunctival hyperaemia in contact lens wearers. Another interesting finding was that grading scales are more likely to be used by optometrists who have recently graduated, have a postgraduate certificate in ocular therapeutics, see more contact lens patients or use other forms of grading scales. National Center for Biotechnology InformationU.

They also believe that increasing the number of intervals to make the grading scale finer may reduce the degree of concordance between repeated measurements of the same clinical event. 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.

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

Grading scale grades are gradung interchangeable, with scales starting either at grade 0 or 1 and with a wide range of values for the highest grade.


Description, sketches and grading scales were used more for recording the anterior eye health of contact lens patients than other patients, as was photography.

Grading conjunctival hyperaemia using a photography-based method. Curr Eye Res ; The variability of grading scores between practitioners can be gradinb and they generally tend to form clusters around whole numbers. Reproducibility of digital image analysis for measuring corneal haze after myopic photorefractive keratectomy.

They require a gading ocular feature to be gauged relative to predetermined images chosen to represent different degrees of the condition of interest on an ordinal scale. Ophthal Physiol Opt ; In the future, image analysis techniques could allow grading of real time or stored images and comparison with population norms without incurring the limitation of photographic or pictorial subjective grading.
