Review
BACKGROUND
Botulinum toxin A (BoNT-A) has grown tremendously in aesthetic dermatology since 2002 when the United States Food and Drug Administration (FDA) first approved its use for treating moderate-to-severe glabellar lines. Blepharoptosis, due to local spread of toxin, is a reported side effect of BoNT-A which, although rare, more frequently occurs among inexperienced practitioners.
OBJECTIVES
The purpose of this review is to highlight the causes and management of eyelid ptosis secondary to BoNT-A administration including new anatomic pathways for BoNT-A spread from the brow area to the levator palpebrae superioris muscle.
METHODS
A literature search was conducted using electronic databases (PubMed, Science Direct, MEDLINE, Embase, CINAHL, EBSCO) regarding eyelid anatomy and the underlying pathogenesis, presentation, prevention, and treatment of eyelid ptosis secondary to BoNT-A. Anatomic dissection has been performed to assess the role of neurovascular pedicles and supraorbital foramen anatomic variations.
RESULTS
Blepharoptosis occurs due to weakness of the levator palpebrae superioris muscle. Mean onset is 3-14 days after injection and eventually self-resolves after the paralytic effect of BoNT-A wanes. Administration of medications, such as oxymetazoline hydrochloride or apraclonidine hydrochloride eye drops, anticholinesterase agents, or transdermal BoNT-A injections to the pre-tarsal orbicularis, can at least partially reverse eyelid ptosis. Anatomic study shows that a supraorbital foramen may be present in some patients and constitutes a shortcut from the brow area directly into the orbital roof, following the supraorbital neurovascular pedicle.
CONCLUSION
Providers should understand the anatomy and be aware of the causes and treatment for blepharoptosis when injecting BoNT-A for the reduction of facial wrinkles. Thorough anatomic knowledge of the supraorbital area and orbital roof is paramount to preventing incorrect injection into "danger zones," which increase the risk of eyelid ptosis.

Review
INTRODUCTION
Myasthenia gravis is characterized by skeletal muscle weakness, the most common initial presentation includes ocular weakness with asymmetric ptosis and binocular diplopia. Around 19-50% of pregnant women with myasthenia gravis will experience a worsening of the disease. The objective of this article was to review the current information regarding the interrelation between MG and pregnancy; as well as its approach.
DEVELOPMENT
Bibliographic search in databases such as PubMed, ScienceDirect, SciELO, Google Scholar and medRxiv. Original articles, reviews, series and case reports between 2013 and 2022 are included.
CONCLUSIONS
Myasthenia gravis would not significantly effects on pregnancy; however, pregnancy can exacerbate the disease, especially during the first trimester or after delivery. The approach to pregnant women with myasthenia gravis must be multidisciplinary and involves the adjustment of pharmacological treatment and constant monitoring.

Review
Blepharoptosis (ptosis) is among the most common disorders of the upper eyelid encountered in both optometric and ophthalmic practice. The unilateral or bilateral drooping of the upper eyelid that characterises ptosis can affect appearance and impair visual function, both of which can negatively impact quality of life. While there are several known forms of congenital ptosis, acquired ptosis (appearing later in life, due to a variety of causes) is the predominant form of the condition. This review summarises the prevalence, causes, identification, differential diagnosis, and treatment of acquired ptosis. Particular attention is paid to the differential diagnosis of acquired ptosis and emerging treatment options, including surgical and pharmacologic approaches.

Review
Of the two common techniques of lower blepharoplasty, the transconjunctival approach is limited to young patients with prominent herniation of lower fat pad without skin excess and the transcutaneous approach to patients requiring skin excision. However, the current trends not only highlight the traditional sculpting of the three orbital fat pads in lower lid blepharoplasty but also additional relocation of the intraorbital fats for correcting the inferior orbital hollowing. The purpose of this review is to analyze the published literature on common types, techniques, indications, and outcomes of the multiple surgical variants of lower lid blepharoplasty often aimed at treating the redundant skin, steatoblepharon, tear trough deformity, lid laxity, and dermatochalasis, thereby to correct the negative vector and inferior orbital hollowing along with effacement of the lid cheek junction. An extensive survey of peer-reviewed literature published in English in electronic databases, as well as bibliographies from cited articles, was conducted. Databases such as MEDLINE PubMed, the Cochrane Library, and Embase were scanned using relevant medical subject heading (MeSH) terms. Clinical studies with a minimum of five study cases were included. Level III evidence, case reports, letters, editorials, and case series with fewer than five eyes were excluded. This article provides a concise overview of available literature and as such no meta-analysis was done due to the narrowed scope of the involved studies and the variety in surgical approaches and techniques of lower lid blepharoplasty.

Review
Congenital blepharoptosis, caused by levator muscle dysgenesis, presents at birth and may lead to disturbed visual development and function. Other causes of ptosis in pediatric patients can be myogenic, neurogenic, mechanical, or traumatic. Timely correction is, therefore, critical, and careful preoperative planning and intraoperative considerations are crucial to achieve optimal outcomes and minimize potential complications. The various surgical techniques, including the frontalis suspension or sling, levator resection and advancement, Müller's muscle conjunctival resection (the Putterman procedure), and modified Fasanella-Servat procedure are each associated with distinct indications, benefits, and drawbacks, necessitating a unique tailored approach to each surgical candidate.

BACKGROUND
Dermoid cyst, a developmental benign choristoma, is the most common orbital tumor of childhood, arising from ectodermal sequestration along the lines of embryonic fusion of mesodermal processes, lined by keratinized stratified squamous epithelium and expanding slowly due to constant desquamation and dermal glandular elements. Approximately 80% are found in the head and neck region and comprise 3-9% all orbital masses.
PURPOSE
It is mandatory to know about the variable presentations of orbital dermoids and the surgical techniques that can be adopted based on the site, extent, age and aesthetic needs, presence of inflammation and possibility of intraoperative rupture.
SYNOPSIS
Orbital dermoids can be classified as juxta-sutural, sutural or soft tissue cysts; superficial or deep; intraosseous or extraosseous, and intraorbital or extraorbital. These smooth, painless, mobile or partially mobile lesions mostly present at the fronto-zygomatic suture with proptosis, displacement, ptosis or diplopia, depending on depth and extent. Therefore, it is important to understand the various presentations and the appropriate surgical techniques.
HIGHLIGHTS
We describe the embryological origin, types and clinical features of dermoids in this video and demonstrate the surgical and minimally invasive techniques for their management.

Review
Ophthalmoparesis and ptosis can be caused by a wide range of rare or more prevalent diseases, several of which can be successfully treated. In this review, we provide clues to aid in the diagnosis of these diseases, based on the clinical symptoms, the involvement pattern and imaging features of extra-ocular muscles (EOM). Dysfunction of EOM including the levator palpebrae can be due to muscle weakness, anatomical restrictions or pathology affecting the innervation. A comprehensive literature review was performed to find clinical and imaging clues for the diagnosis and follow-up of ptosis and ophthalmoparesis. We used five patterns as a framework for differential diagnostic reasoning and for pattern recognition in symptomatology, EOM involvement and imaging results of individual patients. The five patterns were characterized by the presence of combination of ptosis, ophthalmoparesis, diplopia, pain, proptosis, nystagmus, extra-orbital symptoms, symmetry or fluctuations in symptoms. Each pattern was linked to anatomical locations and either hereditary or acquired diseases. Hereditary muscle diseases often lead to ophthalmoparesis without diplopia as a predominant feature, while in acquired eye muscle diseases ophthalmoparesis is often asymmetrical and can be accompanied by proptosis and pain. Fluctuation is a hallmark of an acquired synaptic disease like myasthenia gravis. Nystagmus is indicative of a central nervous system lesion. Second, specific EOM involvement patterns can also provide valuable diagnostic clues. In hereditary muscle diseases like chronic progressive external ophthalmoplegia (CPEO) and oculo-pharyngeal muscular dystrophy (OPMD) the superior rectus is often involved. In neuropathic disease, the pattern of involvement of the EOM can be linked to specific cranial nerves. In myasthenia gravis this pattern is variable within patients over time. Lastly, orbital imaging can aid in the diagnosis. Fat replacement of the EOM is commonly observed in hereditary myopathic diseases, such as CPEO. In contrast, inflammation and volume increases are often observed in acquired muscle diseases such as Graves' orbitopathy. In diseases with ophthalmoparesis and ptosis specific patterns of clinical symptoms, the EOM involvement pattern and orbital imaging provide valuable information for diagnosis and could prove valuable in the follow-up of disease progression and the understanding of disease pathophysiology.
