Double puncta canaliculi may exhibit different clinical presentations.

In this paper, we describe two adult patients who presented with double lacrimal puncta: one of them was asymptomatic and incidentally diagnosed, and the other complained of epiphora. In both patients, unilaterality, preference for the lower lid, and location medial to the normal punctum were common features of the accessory punctum. In the asymptomatic patient, irrigation revealed no obstruction in the punctum or the nasolacrimal drainage system. By contrast, the other patient's nasolacrimal drainage system exhibited obstruction. Therefore, dacryocystorhinostomy surgery and silicone tube intubation were successfully performed. Double lacrimal puncta may be associated with epiphora or dry eye. These manifestations can easily be missed in a routine examination. This report was written to emphasize that unilateral epiphora of dry eye symptoms may be related to supernumerary punctum or canalicular systems and can easily be diagnosed with lid eversion.

RESUMO Neste artigo, descrevemos dois pacientes adultos que apresentaram punção lacrimal dupla: um deles assintomático e diagnosticado incidentalmente, e o outro queixava-se de epífora. Nos dois pacientes, unilateralidade, preferência pela pálpebra inferior e posição medial pelo ponto normal foram características comuns do ponto acessório. No paciente assintomático, a irrigação não revelou obstrução no ponto ou no sistema de drenagem nasolacrimal. No entanto, o sistema de drenagem nasolacrimal do outro paciente exibiu obstrução. Portanto, a cirurgia de dacriocistorrinostomia e a intubação com tubo de silicone foram realizadas com sucesso. O ponto lacrimal duplo pode ser associado à epífora ou ao olho seco. Essas manifestações podem ser facilmente esquecidas em um exame de rotina. Queremos enfatizar que a epífora unilateral dos sintomas de olho seco pode estar relacionada ao sistema de ponto ou canalicular supranumerário e pode ser facilmente diagnosticada com eversão de pálpebra.
