Filter by:The aim of the study is to compare the efficacy and effectiveness of Endoscopic Endonasal DCR with narrow fenstrum approach and Endoscopic Endonasal DCR with wide fenstrum approach .
a prospective randomized study conducted upon 40 eyes of 24 patients with lower punctual stenosis (grade 1 or 2 according to Kashkouli scale) attending at Menoufia University hospitals and Kafr Elsheikh ophthalmic eye center. 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. A Nettelship dilator is used to enlarge the stenotic lacrimal punctum. A single blade of a small Westcott spring scissor or Vannus scissor is placed within the ampulla of the lacrimal canaliculus, with the remaining blade placed on the conjunctival surface of the posterior aspect of the eyelid. The first vertical snip is made at the vertical canaliculus. The second vertical snip is made from the edge of the first snip to create a flap. The final horizontal snip was made at the base. The triangular flap is removed and three sutures are placed, in an interrupted manner, at the posterior wall of the ampulla using 10-0 nylon. The sutures are removed 1 week after the surgery. Topical moxifloxacin 0.5% eye drops and fluorometholone 0.1% eye drops were used four times daily for one week.Patients were then followed up for 6 months after the surgery.
The primary aim of the study is to investigate whether optical coherence tomography (OCT) may be a useful tool for investigating the in-vivo histology of ocular structures in patients with tear film pathology. In epiphora the investigators will image the proximal lacrimal system. In dry eye syndrome the investigators will image the lacrimal gland and also the buccal mucosa. The secondary aim of the study is to investigate the appearance of the normal cornea and conjunctiva under OCT imaging.
