In patients with rheumatoid arthritis (RA), necrotizing scleritis, an ocular manifestation of a systemic vasculitic process, is associated with significant ocular morbidity and high mortality. We present a 60-year-old man with RA who developed necrotizing scleritis and peripheral ulcerative keratitis. The scleritis was refractory to local measures, systemic(More)
We retrospectively evaluated a consecutive series of 45 patients (45 eyes) who underwent trabeculectomy augmented with a single intra-operative 5 minute application of 5-fluorouracil (5-FU; 25 mg/ml). All patients were at an increased risk of subconjunctival fibrosis and surgical failure. The mean follow-up period was 24 months (range 12-42, SD 6.9). The(More)
The accuracy of referral to the glaucoma clinic in Edinburgh was evaluated retrospectively by case note analysis. Two hundred and ninety-five patients suspected of having glaucoma were referred during a 6 month period. Optometrists accounted for 96% of referrals with the remainder being referred directly by the GP. The highest overall detection rates(More)
Let B n be the braid group on n 4 strands. We prove that B n modulo its center is co-Hoppan. We then show that any injective endomorphism of B n is geometric in the sense that it is induced by a homeomorphism of a punctured disk. We further prove that any injection from B n to B n+1 is geometric for n 7. Additionally, we obtain analogous results for mapping(More)
At 130 days of age, 31 female rats that had been subjected in infancy to handling, mother-separation, both, or neither, were injected with d-amphetamine (100 mg/kg, 50 mg/ml, i.p.). The subjects from handled, mother-present litters were the only group that showed increased latency to death. This finding indicated that the maternal behavior elicited by early(More)
AIMS To test if the simple technique of warming lignocaine reduces the pain of injection during local anaesthetic cataract surgery. METHODS Sixty patients undergoing peribulbar local anaesthesia for cataract surgery were allocated randomly to receive either warm (37 degrees C) or cold (room temperature) plain 2% lignocaine for the injection. Pain was(More)
OBJECTIVE To characterize the clinical and pathologic features of cadaveric keratolimbal allograft (KLAL) rejection. DESIGN The study design is descriptive. PARTICIPANTS Four patients (five eyes) with KLAL rejection are reported. INTERVENTION All patients were subjected to slit-lamp biomicroscopy, treatment of rejection, and ultimately required repeat(More)
Twenty-four yearling Quarter Horse fillies were divided into three groups (I) very limited handling, (II) intermediate handling and (III) extensive handling. At about 14 months of age, each horse was preconditioned for 2 weeks and then run in a simple place-learning T-maze test in which it had to locate its feed. Thirty trials were run daily for 20 days,(More)
AIMS To study the efficacy of laser suture lysis in the promotion of filtration and bleb formation during the early postoperative period after trabeculectomy. METHODS This was a prospective study of 20 eyes from 20 patients undergoing trabeculectomy. Patients were entered into the study if, after a trial period of ocular massage, the intraocular pressure(More)
