Uveitis

Brief summary

Optical Coherence Tomography (OCT) machines are non-contact instruments that can provide micrometer scale imaging of biological tissue. Applying the image processing allows us to automatically measure the choroidal thickness with good interclass correlation coefficient to the manual measurements.

Design outcomes

Primary

MeasureTime frameDescription
Submacular choroidal thickness in different stages of the disease5 yearsOCT EDI recordings processed with developed by researchers methodology for image processing

Secondary

MeasureTime frameDescription
The SUN working group grading system for anterior chamber cells1 yearAt each visit anterior chamber will be examined to assess anterior chamber cells (1mm x 1mm slit beam in height and width, when thrown at an angle of 45-60°). The recorded number of cells will be used to determine the grade according to the SUN criteria.
The SUN working group grading system for anterior chamber flare1 yearAt each visit anterior chamber will be examined to assess anterior chamber flare (1mm x 1mm slit beam in height and width, when thrown at an angle of 45-60°). The observed changes will be used to determine the grade according to the SUN criteria.
ETDRS Visual Acuity1 yearVisual Acuity will be performed with ETDRS charts different for right and left eye
NIH grading system for vitreous cells1 yearAt each visit vitreous will be examined to assess vitreous cells (1mm x 3mm slit beam in anterior vitreous). The recorded number of cells will be used to determine the grade according to the NIH criteria.
NIH grading system for vitreous haze1 yearAt each visit vitreous will be examined to assess vitreous haze. The recorded of clarity of posterior pole funduscopy will be used to determine the grade according to the NIH criteria.
AREDS 2008 Clinical Lens Opacity Grading Procedure1 yearUsing AREDS system for classifying cataracts from photographs: AREDS Report No. 4 the lens opacity will be graded
