Modified visual field test for ptosis surgery (Leicester Peripheral Field Test).
BACKGROUND
There is lack of consensus among Primary Health Care Trusts (PCTs) and health insurers on how to reimburse ptosis surgery and upper lid blepharoplasty, as these procedures can be regarded as cosmetic. Standardised photographs are expensive and difficult to achieve, whilst the routine 24-2 visual field lacks the range to detect visually significant superior field defects.AimTo introduce a modified visual field designed to assess the functional disability associated with ptosis and dermatochalasis and to demonstrate the effectiveness of surgery in improving the visual field.


METHODS
Patients who had surgery for ptosis or dermatochalasis between January 2006 and December 2009 were prospectively invited to perform a modified visual field test pre- and post-operatively.


RESULTS
In total, 97 patients amounting to 194 eyes were included in the study. Ninety five eyes had aponeurotic repair with or without blepharoplasty and 77 eyes had blepharoplasty alone. 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. For those who had blepharoplasty alone, 90.9% recorded an improvement in points seen in the modified visual field test and 80.6% had improvement in visual field height.


CONCLUSIONS
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.
