Quantification gradding conjunctival vascular reaction by digital imaging. The increments of the grading scales were best described by a quadratic rather than a linear function. A report can then be exported for practice records without collecting patient personal data. Example of edge detection and colour extraction techniques applied to a selected dashed rectangle area of an image of bulbar hyperaemia.

C42682: Clinical grading scales

Palpebral hyperaemia scale images were well described by colour extraction techniques. Accepted Mar Edge detection filled symbols and relative green colouration closed symbols with grading scale images of corneal staining.

Author information Article notes Copyright and License information Disclaimer. The intensity, incidence angle, and type of grafing will affect the reflections as well as the apparent size and shape of the papillae, and therefore the non-uniform change with increasing photographic scale intensity may be expected. 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.


Variability of clinical researchers in contact lens research.

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

These alternative approaches to record keeping can all be considered as representing good clinical practice. Fieguth PSimpson TL.

Evidence suggests that concordance tends to improve with training or practice. Edge detection filled symbols and relative red colouration open symbols with grading scale images of bulbar hyperaemia. Guillon MShah D. Table 1 summarises the benefits. They require a given ocular feature to be gauged relative to predetermined images chosen to represent different degrees of the condition of interest on an ordinal scale.

If we are working in settings where patients are being seen by multiple practitioners, it is critical that the same scales be used and the same rules applied, to ensure that numbers assigned to appearance by different practitioners match.

Int Contact Lens Clinics ; However, image analysis would have merit in monitoring changes in individual patients with time and the computer could also count the number of segments identified to identify between punctate and confluent type stainingprovide a ratio of the longest to the shortest axis to give an indication of gradng in addition to the measures of edges detected a stable indicator of area and green colouration stain intensity.

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.

Handbook of Contact Lens Management. Such scales vary in the number of images and conditions of interest and can be descriptive, 1, 2 artistically rendered, 3 photographic, 4— 6 or computer generated. Characteristics of corneal staining in hydrogel contact lens wearers.


Editor’s choice Look local: 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 proportion of the image occupied by vessels are more important than relative colouration 15 whereas another indicated both these factors were integral to grading.

Contact Lens Ant Eye ; Acta Ophthalmol ; Social media and SEO success Seven ways: Optom Vis Sci ; The primary reason cited for not using grading scales was a preference for recording clinical data using other means, such as sketches, photographs or written descriptions. 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.

The average time taken to record anterior eye health was 6. Objective measurement of contact-lens induced conjunctival redness. Invest Ophthalmol Vis Sci ; Obviously the difference is only slight and could not be considered of clinical significance. Open in a separate window.

CLAO J ; Vistakon-Synoptik palpebral conjunctivitis images were analysed selecting the palpebral hyperaemia and the area with reflections separately to distinguish between hyperaemia and roughness.
