Punctal stenosis is an important etiological factor that should be considered when assessing patients with epiphora. Anatomically, acquired punctal stenosis is a condition in which the external opening of the lacrimal canaliculus is narrowed or occluded and also can be accompanied by canalicular ductal stenosis.1,2. Defining an anatomical clear cut-off value for punctal stenosis is difficult due to wide variations in patients' demographics. Clinically, punctal stenosis is defined as a punctum size restricting tear drainage in the absence of distal tear drainage abnormalities.2 Acquired punctal stenosis can be involutional, inflammatory, infectious or idiopathic.3,4 Inflammatory endogenous causes include chronic blepharitis, dry eye disease and ocular cicatricial pemphigoid.3 Exogenous noxious stimuli may be chemical such as topical or systemic medications, or physical as irradiation or mechanical. The harmful effect of topical medications such as antiglaucomatous drops, dexamesathone, mitomycin-C and the systemic medications such 5-Fluorouracil or paclitaxel may be related to the medication themselves, the preservatives as benzalkonium chloride in the commercial preparations, or duration of treatment with those medications.3,5-9 The basic ultra-structure response to those various noxious stimuli is early punctal occlusion by edema which is followed by conjunctival overgrowth, keratinization of punctal walls and cicatricial punctal stenosis. Although spectral-domain OCT is still being widely used on the retina, its anterior segment module is considered a new modality for imaging of proximal lacrimal excretory passage and tears meniscus height (TMH). Recent studies showed the ability of using AS-OCT to differentiate between various punctal causes of epiphora and improve the understanding of the lacrimal punctal structure in vivo.10-12 The aim of this work is to evaluate the role of AS-OCT in evaluation the punctal changes after treatment by antibiotics and steroids.
The objective of this study is to evaluate the efficacy of a novel oral supplement (gummy bear) with blueberry powder on reducing dry eye signs and symptoms and assess its safety.
Video display terminals (VDTs) are ubiquitous, and engagement in digital screens has grown substantially across all age groups worldwide. Prolonged exposure to VDTs is associated with the development of various health problems. By now, it is unclear whether transient exposure to VDTs leads to ocular surface changes, especially regarding lipid layer thickness (LLT). This study aim to determine if short-term exposure to light-emitting diodes (LEDs) leads to ocular parameter changes. This is a prospective, cross-sectional study. Patients were recruited at the National Cheng-Kung University Hospital, a tertiary referral center in southern Taiwan, for examination, including best-corrected visual acuity (BCVA), intraocular pressure (IOP), lipid layer thickness (LLT), and blink rates and patterns before and after watching an LED display for 15 minutes. The estimated result is that the LLT and blink rates will decrease after VDT watching.
Cataract surgery is one of the main causes of Dry Eye Disease (DED). This paper aimed at evaluating the prevalence of iatrogenic DED on a population of patients without DED receiving cataract surgery, and the impact of an eyedrop containing hyaluronic acid and gingko biloba (HA-GB, Trium free eyedrops, Sooft srl, Italy). In this phase-IV trial we enrolled 40 patients with no DED. Patients were seen at baseline, day 1, week 1 and week 4. At each visit patients received Ocular Surface Disease Index (OSDI) questionnaire, Anterior segment ophthalmoscopy with grading of conjunctival hyperemia, fluorescein tear break-up time (TBUT), grading of fluorescein corneal staining (epithelial damage); adherence and tolerability using a visual analogue scale were checked at week 1 and 4. At day 0 patients underwent cataract surgery (2.4 mm temporal incision) and were randomized to standard postoperative care (control group) or standard postoperative care + HA-GB given three times a day for 4 weeks (HA-GB group).
AMD (age-related macular degeneration), is the leading cause of blindness in individuals over the age of 55. There is no cure for wet-AMD but anti-VEGF treatments significantly minimize the vision loss over time. To study the correlation between anti-VEGF injection bevacizumab (Lucentis), visual acuity, macular thickness and last but not least reading speed in wet-AMD patients. The study was conducted on 50 eyes of 50 wet-AMD patients. Subjects were monthly treated with an intra-vitreal Lucentis injection for 3 months; further injections were given when a loss of 5 or more letters of visual acuity was observed and/or when the retinal thickness in the affected macular area increased by 100 µm. In addition to a full ophthalmological examination reading speed was investigated via the Radner reading chart before and 3 months after treatment. The collected data was analyzed using paired t-tests.
To compare the efficacy of local injections of two different types of steroid (betamethasone suspension versus triamcinolone acetate) in management of patients with thyroid-related upper lid retraction either isolated or associated with proptosis.
