“…On the orbital surface of the optic canal and the medial aspect of the superior orbital fissure, the periorbita thickens, forming tendinous attachments of the four rectus muscles, the levator palpebrae superioris (LPS), and the SO, creating a tendinous ring (the annulus of Zinn). This dense connective tissue membrane serves not only as an attachment site for muscles, tendons, and ligaments, it is also a support structure for the blood supply to the orbital bones [44].…”

Human prenatal development is divided into an embryonic period and a fetal period. Intense organogenetic activity occurs in the embryonic period of prenatal life, while the fetal period is marked by less intense changes. Knowledge of the embryology of the orbit not only allows insights into how normal variations in the orbital structure arise but also provides an understanding of how congenital deformities occur when normal orbital development goes awry. In order to explore our understanding of the developmental anatomy of the orbit during the fetal period of prenatal life, the authors have summarized the major milestones in orbital morphogenesis, a temporally precise and morphogenetically intricate process. This process can be considered as an anatomic series of complex, well-orchestrated changes in morphology as well as a series of complex biochemical and molecular events that coordinate and control the anatomic development. Identifying and linking signaling pathways and regulatory genes linked with normal orbital morphogenesis is a crucial step to offer patients with chronic or incurable orbital diseases effective treatment options in the future.

“…This pumping function is compromised in patients with facial nerve palsy, which is in part responsible for tearing in those patients. 3 The lacrimal sac drains into the nasolacrimal duct, which is lined by mucosa and enters the nose through the valve of Hasner beneath the inferior turbinate in the inferior meatus. Dacryocystorhinostomy (DCR) surgery bypasses obstruction in the nasolacrimal duct by creating a new orifice into the nose at the level of the lacrimal sac.…”

Background: The lacrimal system includes the tear film of the eye and the tear drainage system. Endoscopic dacryocystorhinostomy (DCR) is a safe and effective method of surgical treatment of nasolacrimal duct obstruction. The anatomy of the nasal cavity is better visualized endoscopically and sac is approached under vision and hence the results are decided at the time of surgery. Methods: Present clinical study was conducted in tertiary medical centre from July 2015 to July 2016. Total 50 patients with epiphora as evidenced by nasolacrimal duct blockage on sac syringing were included in the study. Children less than 10 years and revision cases were excluded. These patients underwent DCR without stenting. Results: Out of the 50 patients, 60% were males and 40% were females. Surgical success was deﬁned as anatomical patency and symptomatic relief at the end of the follow up period which was observed in 45 of 50 (90%) patients. Incidence of complications was as low as only 5 patients. These patients were followed up for 6 months with no complaints of epiphora. Conclusions: Endoscopic DCR is a safe and effective method of surgical treatment of nasolacrimal duct obstruction. It gives equivalent symptomatic relief from epiphora when compared to external method. Thus, we can minimize complications, discomfort, cost of stenting and follow up visits after endonasal surgery. Due to higher success rate, minimal invasiveness and high patient satisfaction as compared to other procedures, it has gained more popularity.
