In screening fields, you are testing whether the retina is on or off, while in threshold testing you are testing how dim a light you can perceive? 0000049511 00000 n However, a recent review of 141 medical records of patients with dermatochalasis found that nearly 87% of patients with keratoconjunctivitis sicca (KCS) had subjective improvement of symptoms after upper lid (UL) blepharoplasty.3 This suggests that UL blepharoplasty may be a useful element in the treatment of patients with both dermatochalasis and dry eye. Most often, as long as everything else is stable (IOP, ONH appearance), we just reorder these fields in a few months time. We aim to use this new assessment tool to demonstrate the functional disability associated with these conditions and the effectiveness of surgery in improving the superior visual field. As a very, very general guideline, you can look at the density / size of the field defect, the pattern standard deviation, and the mean deviation (MD) to see if it is worsening. It is essential to differentiate dermatochalasis from the less common blepharochalasis, which is the expansion of the orbital septum and preseptal muscles secondary to repeated angioneurotic edema and is seen less commonly in younger patients.
