If the drop floats, the test concludes there is no evil eye involved. If the drop sinks, then it is asserted that the evil eye is cast indeed. Another form of the test is to place two drops of olive oil into a glass of water. If the drops remain separated, the test concludes there is no evil eye, but if they merge, there is. There is also a third form where in a plate full of water the "healer" places three or nine drops of oil. If the oil drops become larger and eventually dissolve in the water there is an evil eye. If the drops remain separated from water in a form of a small circle there isnt. The first drops are the most important and the number of drops that dissolve in water indicates the strength of the evil eye. Note that a secret chant is spoken when these tests are conducted. The words of the chant are closed practiced and can only be passed from man to woman, or woman to man.There is another form of the "test" where the "healer" prepares a few cloves by piercing each one with a pin. Then she lights a candle and grabs a pinned clove with a pair of scissors. She then uses it to do the sign of the cross over the afflicted whilst the afflicted is asked to think of a person who may have given him the evil eye. Then the healer holds the clove over the flame.
The following are specific characteristics:
Malformed or absent (aplasia) thumb
A thumb that looks more like a finger
Partial or complete absence of a radius
Shortening and radial deviation of the forearms
Triphalangeal thumb
Duplication of the thumb (preaxial polydactyly)

Other Various Symptoms
People with the combination of Duane anomaly and radial ray malformations may have a variety of other signs and symptoms. These features include:
Unusually shaped ears
Hearing loss
Heart and kidney defects
A distinctive facial appearance
An inward- and downward-turning foot (a clubfoot)
Fused vertebrae. Causes
Genetics
Duane-radial ray syndrome is caused by mutations in the SALL4 gene which is a part of a group of genes called the SALL family. This gene plays an important role in embryonic development by providing instructions to make proteins that are involved in the formation of tissues and organs. SALL proteins act as transcription factors in that they attach themselves to certain regions in DNA in order to help control certain gene activities. Due to the mutations in the SALL4 gene, proteins can not be made because one copy of the gene in each cell is stopped from performing its duty. These mutations are heterozygous and can be nonsense, short duplications, or deletions. At this time, there is no clear reason as to why a reduced amount of the SALL4 protein causes the symptoms of Duane-radial ray syndrome and similar conditions.Duane-radial ray syndrome is inherited through autosomal dominance meaning that a mutation in one copy of the SALL 4 gene is all it takes to cause this syndrome.
