At times, a proboscis may also be noted with this condition. Herein, we present a case of a 13-year-old boy who presented to us with heminasal agenesis with concomitant microphthalmos, leucomatous corneal opacity, blepharoptosis, dacryocystocoele and maxillary hypoplasia. The child underwent a modified transeptal external dacryocystorhinostomy with placement of a lacrimal stent. There was significant improvement of epiphora and discharged following surgery. Heminasal aplasia with dacryocystocoele is surgical challenge; however, a well thought out surgical approach can yield satisfactory outcomes. %U https://casereports.bmj.com/content/bmjcr/15/1/e245424.full.pdf
