The purpose of this study to is to determine the incidence of post-operative ptosis in
patients undergoing vitreoretinal surgery. An additional purpose is to identify
pre-operative and intra-operative factors which correlate to the development of
post-operative ptosis in vitreoretinal surgery cases.
patients undergoing vitreoretinal surgery. An additional purpose is to identify
pre-operative and intra-operative factors which correlate to the development of
post-operative ptosis in vitreoretinal surgery cases.
This study will evaluate patients who will undergo vitreoretinal surgery at UCSF Medical
Center and San Francisco General Hospital. After informed consent has been obtained, the
measurement of eyelid parameters such as levator function, palpebral fissure height, upper
eyelid crease height, MRD1 and MRD2 will be collected at pre-operative and post-operative
follow up visits. External eye photographs taken at each visit will be evaluated by a masked
reader who will calculate the eyelid parameters. Dermographic data and intraoperative
factors such as operative time and type of procedure will be collected. For statistical
analysis, Repeated ANOVA, Paired t-test, Wilcoxon signed rank test, Chi-square test and
Pearson's correlation analysis will be calculated with SPSS software.
