21 sty 2011 · We therefore designed a modified visual field test specifically to assess ptosis and dermatochalasis. We aim to use this new assessment tool to demonstrate the functional disability associated...
Leicester Peripheral Field Test (LPFT) • Modified Humphrey Visual Field Test; automated, operator-independent, static perimetry test evaluating a 48° superior field, using a 35-point grid (14-point grid in inferior field used as reference) • Shifted centre of fixation allows for more natural eyelid positioning and reduction of compensatory ...
29 kwi 2021 · The HVF Test is an automated static perimetry test using an HVF analyser, in which static illuminated targets briefly appear in the field and patients indicate when a target is seen.
Our modified visual field assessment is a quick and easy way to assess patient disability associated with ptosis and dermatochalasis. Surgery improves the demonstrated defect, confirming that ptosis and dermatochalasis can be considered a functional rather than cosmetic issue.
21 sty 2011 · This study was designed to test the ability of a portable computer driven, head mounted visual field testing system to perform automated perimetry on patients at their bedside and to...
This modified test has a sensitivity of 98.8% of detecting ptosis. For patients who underwent ptosis surgery with or without blepharoplasty, 84.2% recorded an improvement in points seen with the test and 81% recorded an improvement in visual field height.
We present here a modified visual field test (Leicester Peripheral Field Test), which is valid, quick and easy to perform. It demonstrates the visual field defects associated with both ptosis and dermatochalasis, and illustrates the improvement in visual function after corrective surgery.
