Study population: Patient who undergo vitreoretinal surgery at the University of California, San Francisco, and San Francisco General Hospital.

Brief summary: 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.

Detailed description: 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.

Eligibility criteria: Inclusion Criteria:

* Patients who have vitreoretinal surgery from January 2013

Exclusion Criteria:

* Minors, younger than age 18.
* Patients who have pre-existing ptosis at baseline in the operative eye.
* Patients who are not able to cooperate with eyelid ptosis measurements
