Amblyopia due a dentigerous cyst. Case report and literature review.

PURPOSE: The goal of this article is to present an infrequent clinical case and to review the available literatura, with an emphasis on ophthalmological symptoms. METHODS: We present the case of a 4-year-old girl with a large dentigerous cyst on the maxillary bone, who had long-standing unilateral epiphora associated with progressive ocular dystopia, facial asymmetry and ipsilateral amblyopia. A multidisciplinary approach was taken by the maxillofacial surgery, ophthalmology and optometry teams. This included systemic antibiotic administration, surgical cyst drainage and amblyopia treatment. The literature review was carried out in the MEDLINE database through the free electronic access to PubMed in March 2020. RESULTS: At the 6-month follow-up, the patient was asymptomatic. The most common symptoms of dentigerous cysts are epiphora 36.8%, ocular dystopia 31.2%, diplopia 21.1%, proptosis, nasolacrimal duct obstruction and blurred vision at 10.5%. Amblyopia has not been reported. CONCLUSIONS: Dentigerous cysts are benign odontogenic cysts, which can be found in the jaw and less frequently on the maxillary bone. They are usually asymptomatic, and the occurrence of ophthalmic complications is very infrequent. Multidisciplinary management is essential to avoiding long-term morbidity of maxillary dentigerous cysts and should include an ophthalmologist.

Lacrimal Puncta Agenesis in Kabuki Syndrome.

Kabuki syndrome (KS) is a rare congenital disorder characterized by multiple systemic anomalies and facial characteristics. Here, the authors present the first case, to the best of the authors' knowledge, of bilateral lacrimal puncta agenesis in a patient with KS.#8232;The proband patient was a 29-year-old woman diagnosed with this syndrome, brought to our office due to recurrent conjunctivitis where agenesia of lacrimal puncta was observed. Therapeutic options were exposed but, as the concomitant medication (topiramate) produced ocular dryness, conservative treatment was decided. Diagnosis of KS is challenging because it is a complex syndrome with many associated findings. The authors recommend taking into account the agenesis of lacrimal points in the differential diagnosis of KS if it is associated with other phenotypic alterations as well as including lacrimal examination in patients with KS diagnosis. The authors emphasize the importance of individualizing treatment since drugs used for the systematic management of these patients can influence tear symptoms.
