The Severity level of Ptosis is divided by determining the
portion of upper limbus covered by the lid margin. Ptosis level is mild if its
2mm, moderate if its 3mm and severe if its 4+ mm. In second step we determine
the peripheral vision affected by upper eyelid. An instrument known by
Perimeter is used to measure the peripheral vision in upper half of eyelid
vision. They check each eye independently. Lights are flashed on screen on
different location for a short duration of time and person is instructed to see
at a central target. If the person is able to see the light, he will push the
buzzer. If no response is made by the person it means the droopy eyelid made
him incapable to see the light. By following this procedure the extent of
visual loss is determined. Photographs are also taken to determine the resting
position of eyelid. Normally the photography session is instructed by Insurance
company if surgery is insured to determine whether its medical reason or
cosmetic reason of performing the Ptosis blepharoplasty.
Some of the patients take some type
medicine which make the blood thinner ,this will increase the flow of blood
during Ptosis surgery which may result in adverse effect .So some type of
medicine must be avoided if you are thinking about performing surgery. Like
Coumadin, Plavix, aspirin or any product containing anticoagulant (blood thinner)
must be stopped 10 to 12 days prior to
surgery. Other things like Chinese black fungus or supplements containing
vitamin E are must be discontinued one week prior the Ptosis blepharoplasty
surgery. There may be other supplements which effect the blood clotting will be
discussed at the time of consultation by the physician.
These are
some of the testing which must be taken in care before performing the Ptosis
blepharoplasty surgery.
