“…The most common cause of tearing was nasolacrimal duct obstruction in the study of Williams et al [4]. In fact nasolacrimal duct obstruction is the most frequent etiology of epiphora in infants [5,6]. Sometimes dry eye was not thought as the cause of tearing.…”

Aim: To determine the importance of Schirmer test in elderly patients with epiphora. Material and Method: A prospective study on the consecutive patients whose ages are 50 or more with a chief complaint of tearing. The cause of tearing was determined on the basis of the clinical examination including slit lamp examination, Schirmer test, dye disappearance test and irrigation test. The patients having eyelid and conjunctival abnormalities other than pinguecula and pterygium were not recruited in the study. Results: This study included 132 patients with a mean age of 68.7 years. Nasolacrimal system abnormalities were detected in 16 eyes (6.1%). The number of eyes with a Schirmer value of 9 mm or lower was 95 (36.0%). The study population was divided into two groups in respect to the mean age. The patients under the mean age formed group 1 and the elderly patients formed group 2. The statistical analyses were performed between two groups and between two sexes. The only significant difference was detected in the comparison of the groups in respect to Schirmer test results (p<0.01). Lower Schirmer test results were obtained in the group 2 including the patients over the age of 68 years. Conclusion: Epiphora in a normally appearing eye of an elderly patient should first bring the dry eye into mind. So the testing for the dry eye is more important than the dye disappearance test and the irrigation test in patients with a complaint of tearing.

“…In cross-section, the smallest units of secretory lacrimal glands, known as acini, appear as ring-like structures. Acini comprise approximately 80 % of the total mass of the lacrimal gland and are essentially composed of serous secretory cells that resemble grape-like structures on a platform of basal myoepithelial cells [236]. Acinar cells are polarised secretory cells that only secrete in one direction; this is achieved by a ring-like tight junction that surrounds the cells, with a lumen at the centre [237].…”

Contact Lens and Anterior Eye

View full text Add to dashboard Cite

A key element of contact lens practice involves clinical evaluation of anterior eye health, including the cornea and limbus, conjunctiva and sclera, eyelids and eyelashes, lacrimal system and tear film. This report reviews the fundamental anatomy and physiology of these structures, including the vascular supply, venous drainage, lymphatic drainage, sensory innervation, physiology and function. This is the foundation for considering the potential interactions with, and effects of, contact lens wear on the anterior eye. This information is not consistently published as academic research and this report provides a synthesis from all available sources. With respect to terminology, the report aims to promote the consistent use of nomenclature in the field, and generally adopts anatomical terms recommended by the Federative Committee for Anatomical Terminology. Techniques for the examination of the ocular surface are also discussed.

“…Nasolacrimal duct obstruction (NLDO) is a congenital or acquired occlusion of the lacrimal drainage system, resulting in chronic epiphora, mucus discharge, or dacryocystitis. 1,2 Congenital NLDO is caused by membranous obstruction or anatomic stenosis within the lacrimal duct and frequently resolves with conservative management within the first year of life. 1 Acquired cases occur later in life, and may arise idiopathically or secondary to precipitants such as infection, trauma, or prior sinonasal or orbital surgery.…”

Purpose: Piezosurgical tools utilize high-frequency ultrasonic oscillations to selectively cut mineralized bone and minimize damage to soft tissue and mucosa. The purpose of this study was to directly compare outcomes in external dacryocystorhinostomy (DCR) using a piezoelectric ultrasonic bone aspirator (UBA) versus a high-speed electric drill with a diamond burr. Methods: A retrospective chart review was conducted on 145 consecutive patients who underwent external DCR by a single oculoplastic surgeon between 2012 and 2017. Collected data included baseline patient characteristics, presenting symptoms, operative details and complications, and postoperative symptoms. Results: One hundred and seventy-three primary external DCRs performed on 145 patients were included in this study. In total, 61.3% of cases were performed with the UBA and 38.7% with the high-speed drill. Most patients were white (92.4%) and female (67.6%), with a mean age of 57.6 years (range 1-93). Surgical success was achieved in 94.3% of patients in the UBA group and 94.0% in the drill group, with no significant differences between the two arms (p=0.36). Patients who experienced persistent nasolacrimal duct obstruction after surgery underwent endoscopic revision. Operative time was shortened for cases utilizing the UBA (38.9 mins) instead of the high-speed drill (44.7 mins; p=0.01). No significant intraoperative complications occurred in either group. Conclusion: The UBA offers comparable outcomes and complication rates to more conventional surgical tools for external DCR. Excellent outcomes, ease of adoption, and potential surgical time savings make the UBA an appealing option for both novice and experienced surgeons.
