Differential diagnosisTriple-A syndrome

Alacrima refers to an abnormality in tear production that could mean reduced tear production or absent tear production. Because a lack of tears presents in only in a few rare disorders, it aids in diagnosis of these disorders, including Triple-A syndrome and NGLY1 deficiency.[1][2][3]

Alacrima can be formally diagnosed through a Schirmer's test.
