Use of hyaluronic acid gel in the treatment of lagophthalmos in sunken superior sulcus syndrome.

Purpose: To evaluate the use of hyaluronic acid gel in the management of lagophthalmos in sunken superior sulcus syndrome.

Introduction: Lagophthalmos associated with orbital fat atrophy and deep superior sulcus is a known entity described previously. Orbital fat atrophy results in deep superior sulcus where skin, orbicularis muscle, and orbital septum retract posteriorly in the deep superior sulcus, leading to lagophthalmos from suboptimal orbicularis function and effective skin shortening.

Modulating neuromuscular junction density changes in botulinum toxin-treated orbicularis oculi muscle.

Purpose: Botulinum toxin A is the most commonly used treatment for blepharospasm, hemifacial spasm, and other focal dystonias. Its main drawback is its relatively short duration of effect. The goal of this study was to examine the ability of corticotropin releasing factor (CRF) or antibody to insulin growth factor I-receptor (anti-IGFIR) to reduce the up-regulation of neuromuscular junctions that are associated with return of muscle function after botulinum toxin treatment.

A caruncular choristoma presenting as an eyelid mass in an infant.

A 7-week-old patient presented for evaluation of a congenital eyelid mass. Following surgical excision of the lesion, histopathologic diagnosis of caruncular choristoma was made. To the authors' knowledge, this is the first report of caruncular tissue presenting as an external eyelid mass.

Update on botulinum toxin and dermal fillers.

Purpose Of Review: The art and science of facial rejuvenation is an ever-evolving field of medicine, as evidenced by the continual development of new surgical and nonsurgical treatment modalities. Over the past 10 years, the use of botulinum toxin and dermal fillers for aesthetic purposes has risen sharply. Herein, we discuss properties of several commonly used injectable products and provide basic instruction for their use toward the goal of achieving facial rejuvenation.

Use of DermaMatrix graft in oculoplastic surgery.

Purpose: The use of acellular human dermal allografts has become widely accepted in oculoplastic surgery. However, the literature only describes the use of AlloDerm as the only source of acellular human dermis. The authors describe our experience using DermaMatrix in oculoplastic surgery.

Intravascular lymphoma presenting as an orbital mass lesion: a case report.

We describe a case of intravascular lymphoma that presented as an orbital mass lesion. A 77-year-old female presented with longstanding fatigue and one-month of diplopia. Magnetic resonance imaging (MRI) revealed a frontal lobe brain lesion and a right orbital mass.
