An objective assessment of that part of the spectrum of ophthalmic eyelid surgeries thatfocuses on correcting the position of entropy (e.g. ectropion, ptosis surgery) is verydifficult - although it is possible to use different measuring parameters (distance ofpupillary reflexes from the edges of the eyelid), comparing different distances on theface, exophthalmometry or the lid laxity test - the so-called snap-back test, but allthese methods are based either on the subjective assessment of the examiner or on thecorrectness of the attached ruler, and their objectivity is therefore very low.
The goal of the project is to develop a methodology for evaluating the results of
operations using a stereo photographic system, to objectively evaluate the functionality
and results of various eyelid operations, and subsequently to expand the use of the
device in other ophthalmological indications.
Different files will be created where the effect of different operations will be
monitored in parallel.
Lateral canthal hinge surgery will be evaluated in the pilot group, and ptosis surgery
through an anterior approach will be evaluated in the second group.
In all patients, the position of the eyelids, their change before and after surgery, the
periorbital volume, and the relation of the eyelids to the periorbital landscape will be
assessed metrically.
The Vectra M3 device will be used for the measurement.
The expected cohort size is 40 patients in each group.
Other: Vectra M3 imaging
Study subjects from both arms will undergo Vectra M3 imaging to evaluate the result of
the surgery.
