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.

Time frame: 1 year
The SUN working group grading system for anterior chamber cells
At 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.
Time frame: 1 year
The SUN working group grading system for anterior chamber flare
At 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.
Time frame: 1 year
AREDS 2008 Clinical Lens Opacity Grading Procedure
Using AREDS system for classifying cataracts from photographs: AREDS Report No. 4 the lens opacity will be graded
Time frame: 1 year
NIH grading system for vitreous cells
At 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.
Time frame: 1 year
