If significant glaucomatous loss is present, false negatives should not deem a test unreliable if it otherwise appears reliable.9. Visual field testing is also very difficult for younger children, patients with mental disabilities or developmental delay, or anyone with slowed reflexes or poor attention span. This is testing visual fields with fingers only. During this test, you will sit in front of a bowl-shaped device, called a perimeter. Determining if the rate of progression will affect visual function and quality of life is important when making the decision to proceed with escalating therapy that carries increased risk of side effect. Trauma, systemic disease like connective tissue disorders or thyroid eye disease, idiopathic inflammation of the eyelids known as blepharochalasis, or previous surgery can potentiate these changes. This finding has been show to have 94% specificity.11 GHT borderline is displayed when the p value is between 1% and 3%. Genetic predisposition and familial inheritance are the strongest predisposing factors to dermatochalasis. The patients current prescription and age are necessary data that the machines needs to calculate the trial lenses. The software uses the data to map out the patient's visual field.
