RESUMO
Dry eye can initially cause mild symptoms of irritation and may rapidly progress to corneal scarring and blindness. Tear substitutes can only help for mild cases. With the advancement in microsurgical techniques, an option of transferring vascularized salivary glands has shown positive results. We present a case of a 5-year-old boy with congenital alacrimia with ocular surface damage. Vascularized autologous submandibular gland transfer was considered as a viable option for this patient. We performed the gland transfer in two separate stages for the two eyes (1 year 5 months apart). The patient was evaluated for up to 2 years for the right eye and for 7 months for the left eye. Dry eye workup showed drastic improvement (right > left). Biochemical analysis showed gradual transition to resemble that of natural tears. This procedure can result in significant symptomatic improvement and can be a promising treatment option for cases of severe dry eye.
