The extensive differential diagnosis of PCG is presented in Table 11-8. PCG should be considered in the differential diagnosis of epiphora in children. PCG is a relatively rare disease and may go undetected or be misdiagnosed by primary care doctors and general ophthalmologists. Mild cases may be misdiagnosed as nasolacrimal duct obstruction, resulting in a delayed PCG diagnosis and irreversible damage. Physicians must be vigilant in their examination and urgently refer infants presenting with the classic triad of epiphora, photophobia, and blepharospasm to a specialist. Left untreated, almost all cases of PCG will progress to blindness.
