Bilateral Type-I Duane's Retraction Syndrome with bilateral Crocodile Tears: A Case Report.

BACKGROUND: Duane's retraction Syndrome is a congenital form of strabismus characterized by horizontal eye movement limitation and globe retraction with palpebral fissure narrowing in attempted adduction. It may be associated with co-existing ocular and systemic pathologies. Crocodile tears, or a paradoxical gustatory lacrimal reflex can be either congenital or acquired. The congenital cases typically are associated with Duane's syndrome in most of the cases. CASE: We present in our case report, uncommon case of bilateral Duane's syndrome with bilateral crocodile tears - both of which can be assumed to be of probably central origin. Though several cases have been reported, there are very few from the Indian subcontinent. Here, we also review the literature of the syndrome with crocodile tears. CONCLUSION: All cases of Duane's retraction syndrome warrant a thorough screening for coexisting ocular and systemic abnormalities. Ours is a classic report of bilateral Duane's syndrome with bilateral congenital crocodile tears, the coexistence of these two anomalies emphasising the aetiology to be anomalous innervation occurring at central level i.e. is brain stem.

Botulinum toxin in the treatment of muscle specific Oro-facial pain: a literature review.

Facial pain associated with temporomandibular joint (TMJ) and surrounding structures has been a challenge to clinicians as far as diagnosis and management is concerned. Complexity of anatomical structures within a small area, function of teeth and surrounding periodontal ligament, action of muscles, pathologies, lack of diagnostic investigations, all these complicate specific diagnosis of TMJ disorders. Various classifications have been designed and studied to help diagnose and treat TMJ related disorders, of which the simplest one is pain from TMJ proper and surrounding muscles. Many treatment modalities to treat pain arising from muscles around TMJ like splints, mouth restriction exercises, injection of sclerosing agents etc. have been used with various degrees of success. Botulinum toxin has been shown to be effective in the treatment of oro-facial pain due to muscular disorders and the same is discussed in detail in this review literature.
