PURPOSE OF STUDY To determine the efficacy of Nd:YAG vitreolysis and pars plana vitrectomy in the treatment of vitreous floaters. METHODS This is a single centre retrospective study of 31 patients (42 eyes) who underwent 54 procedures, Nd:YAG vitreolysis or pars plana vitrectomy, for the treatment of vitreous floaters between January 1992 and December(More)
During the last decade, the presumed etiology of glaucoma has moved from a pure pressure concept to a combined mechanical and vascular theory. Evidence of a localized vascular insufficiency leading to perfusion deficits of ocular structures, including the optic nerve head, the retina, the choroid, and the retrobulbar vessels, is now clear.

Software Engineering graduates are expected to enter the workforce with both technical and soft skills. In addition, software quality is a topic that is becoming increasingly important both because of educational and industry requirements. Software engineering lecturers need to bring their research into the classroom. Bringing all of these together can pose(More)
PURPOSE To determine the relation between the fluorescein transit test time and postoperative relief of epiphora in patent dacryocystorhinostomies. METHODS A retrospective study of 40 patients who underwent 42 external dacryocystorhinostomies between January 1994 and January 2000 was performed. Postoperative symptomatic success was assessed by a(More)
AIM To determine the long term success of external dacryocystorhinostomy (DCR) in adults with acquired partial nasolacrimal obstruction. METHODS A retrospective study of 50 external dacryocystorhinostomies with silicone intubation performed for partial nasolacrimal obstruction, was undertaken. Preoperative lacrimal scintigraphy divided drainage(More)
We describe a 1-stage surgical technique to treat vitreous floaters. Phacoemulsification is combined with a deep anterior vitrectomy through a posterior curvilinear capsulorhexis followed by implantation of a posterior chamber intraocular lens. The technique was used in 10 eyes of 6 patients. Six months postoperatively, 8 eyes had a best corrected visual(More)
Software engineering lecturers are faced with the teaching of concepts which sometimes are not easy for inexperienced students to understand.  Therefore, it can be useful to consider and use non-traditional teaching methods which can improve students’ learning.  In this paper, we discuss problem-based learning and how its use(More)
AIM To report periorbital dermatitis as a late side effect of topical dorzolamide hydrochloride (Trusopt), a drug used to reduce intraocular pressure. METHODS A retrospective study of 14 patients who developed periorbital dermatitis while using topical dorzolamide hydrochloride was undertaken. Six patients underwent patch testing for sensitivity to(More)
