Filter by:135 eyes of 135 patients treated between 2005 and 2017 will be included in this study. The diagnosis of functional epiphora was made based on a patent lacrimal system with a delay in the fluorescein dye disappearance test (FDDT) or dacryoscintigraphy (DSG) without any ocular surface or eyelid abnormalities. The absence of epiphora and normalization of FDDT postoperatively was defined as success. The study's hypothesis is that external DCR with a suitable technique will have better results compared to endonasal and transcanalicular DCR
to investigate the clinical outcomes and tolerances of Cyclosporine A (CsA) in treating epiphora in eyes with acquired punctum stenosis
This is a clinical trial study that was conducted on patients with punctal stenosis.We studied the diameter of stenosed puncta before and after treatment with preserved free steroid eye drops using AS-OCT.
Patients with lacrimal dacryocystocele were chosen for the study. Dacryocystorhinostomy were done for them after their evaluation.
Detect anatomical level of acquired lacrimal passage obstructions among patients with epiphora. They were evaluated and divided into four groups Punctal, Canalicular, Nasolacrimal duct and Mixed groups according to level of obstruction
a prospective non-randomized study conducted upon 24 patients with severe lower punctual stenosis (grade 0 according to Kashkouli scale) attending at Menoufia University hospitals. The upper punctum and canaliculus were patent. All patients were complaining of epiphora and had a thorough ophthalmological examination including dye disappearance test, and slit-lamp examination. Pigtail probe was used from patent upper punctum to detect the lower stenosed punctum which was opened with a scalpel. Syringing of the lower lacrimal passages was done to confirm its patency and self retaining silicone bicanalicular stent was inserted. The silicone tube was left in place for 6 months before it was removed. Patients were then followed up for 1 year after the surgery.
Cross-over comparison of lipid layer thickness and dry eye symptoms with two artificial tear formulations.
Assessing efficacy of punctal dilatation with insertion of perforated punctal plugs for the management of acquired punctal stenosis due to allergic conjunctivitis in otherwise healthy patients.
In vivo confocal microscopy (IVCM) used in tertiary care ophthalmology centers is performed with two reflectance microscopes attached on a mounting with limited movement along the XYZ axes. Consequently, ocular diseases in the central area have been described (mostly cornea and adjacent conjunctiva). Two dermatology IVCM (an handheld small IVCM and a multifluorescent one) present significant innovations that the investigators want to assess in ophthalmology for the diagnosis of conjunctiva, cornea, eyelid and lachrymal tract diseases. The handheld IVCM have unlimited degrees of freedom and a small diameter objective. It could dramatically increase the area accessible to IVCM (whole conjunctiva, eyelids, proximal lachrymal tract) (part 1 of the present study). The fluorescent IVCM allows the use of a wide range of fluorescent markers liable to increase the specificity of the diagnosis by revealing staining patterns corresponding to a specific disease and not to others (part 2 of the study)
Background Because dacryoliths occur at low frequency, few studies have focused on their composition. The investigators aimed to present findings from morphological, chemical, and mineralogic analysis of 86 dacryoliths. Methods The team studied 86 dacryoliths obtained during 832 dacryocystorhinostomies (DCR) performed for postsaccal obstruction. The samples were analyzed with atomic infrared spectrometry (80 samples), amino acid analysis (17 samples), scanning electron microscopy, and an electron microprobe with an energy dispersive detector (7 samples).
