ABSTRACT
This study was to determine whether general anaesthesia plus retrobulbar block would be a better anaesthetic technique than general anaesthesia alone in retinal detachment surgery. Twenty-eight patients were allocated randomly to either general anaesthesia with retrobulbar block or general anaesthesia alone. The anaesthetist involved was blinded as to whether a retrobulbar block was performed or not. Significantly fewer patients in the general anaesthesia plus block group complained of postoperative pain than patients in the general anaesthesia group (21.4% as compared with 64.3%, p less than 0.05). Those who received general anaesthesia plus block recovered significantly more rapidly than those receiving general anaesthesia alone. The time to opening of eyes on command (p less than 0.05), telling the correct date of birth (p less than 0.01), reaching a full recovery score (p less than 0.005) and performing a simple motor task (p less than 0.025) was shorter in patients with general anaesthesia plus block. Thus general anaesthesia plus retrobulbar block was superior to general anaesthesia alone in terms of pain and recovery after operation.

The occurrence of ocular complications among 62 recipients of functioning renal transplants was reviewed 6 months to 7 1/2 years after transplantation. Posterior subcapsular cataracts were found in 29 (46.7%). A positive correlation was found between the development of cataracts and the total dose of corticosteroid, the number of days on which the dose exceeded 100 mg, and the number of rejection episodes treated with high doses of corticosteroid. Identification of specific high-risk periods in regard to cataract formation could lead to use of preventive therapy, as yet undetermined, during these periods. Lower doses of corticosteroids should be used to treat rejection episodes.

Twelve diabetics with terminal renal failure were maintained on chronic peritoneal dialysis (PD) for 2-28 months (average 10 months). 7/12 survived more than 1 year. Blood glucose levels were well controlled by the use of supplemental, intradialysis, intraperitoneal insulin. The incidence of dialysis-related complications, including peritonitis was not significantly higher than in controls. Neurophysiological studies revealed a high incidence of neuropathy initially with progression in most patients. Radiological studies revealed initial vascular calcifications in 7 out of 12 patients with progression in 4. Retinopathy did not progress significantly. PD is a suitable alternative to hemodialysis in the management of end-stage diabetic nephropathy.

Increasing public concern led the Canadian Ophthalmological Society, in January 1974, to form a committee to study the incidence, types and causes of hockey eye injuries and to devise means of reducing such injuries. Retrospective and current studies were undertaken, and face protectors were tested. In both pilot studies, sticks were the commonest cause and the highest number of eye injuries was in players 11-15 years old. An average of 15% of all injured eyes were rendered legally blind. Cooperation with hockey authorities has resulted in changed rules and their sticter enforcement, and formulation of standards for face protection approved by the Canadian Standards Association. In this interim report the committee recommends that all amateur hockey players wear eye protectors and urges ophthalmologists to participate in efforts to improve the design of protective equipment.
