BACKGROUND Amblyopia results in deficits in a number of visual functions in both the amblyopic and dominant eye. The present work describes oscillatory movement displacement thresholds (OMDT) in childhood amblyopia. METHODS The OMDT from the dominant and amblyopic eyes of 50 orthoptic patients (aged 74 (SD 16) months) were compared with those from a group of 24 controls (79 (21) months). OMDT...

RED filter treatment was devised by Brinker and Katz (1963) to overcome some of the disadvantages inherent in conventional pleoptic methods-the necessity for regular attendance at hospital, lengthy sessions with the ophthalmologist, expensive equipment, and the difficulty of obtaining full co-operation and attention from the younger patients. The principle of the red filter is related to the fa...

OBJECTIVES A comparison of parent initiated preschool surveillance, using personal child health records, with the then current system of child health surveillance using child health records. DESIGN Prospective, controlled trial with randomisation of five general practices into two groups. SETTING Five general practices, a well baby clinic, and an orthoptic clinic at Yeovil District Hospital...

JOHANNESBURG IN ophthalmology there are two schools of thought, the physiological and the physical or mechanical school. Thus Williamson-Noble', dealing with my method of treating eyestrain, states: "curiously enough, Stutterheim designates the condition which his exercises are designed to improve as " involuntary convergence," whereas, as you will shortly see, it is the ability to perform the ...

AIM To determine whether changes in orthoptic status take place during withdrawal from heroin and/or methadone. METHOD A prospective study of patients, using a repeated measures design, attending a 5 day naltrexone compressed opiate detoxification programme. RESULTS 83 patients were seen before detoxification (mean age 27.1 (SD 4.6) years) and 69 after detoxification. The horizontal angle o...

PURPOSE OF REVIEW Considerable uncertainty and controversy has existed concerning the management of convergence insufficiency. Only recently there have been significant scientific studies published that compare the effectiveness of the commonly prescribed treatments. This paper reviews the most recent research and literature on convergence insufficiency and its treatment. RECENT FINDINGS The ...

OBJECTIVE To identify and assess strategies for evaluating the impact of mobile eye health units on health outcomes. DESIGN Systematic literature review. SETTING Worldwide. PARTICIPANTS Peer-reviewed journal articles that included the use of a mobile eye health unit. MAIN OUTCOME MEASURE(S) Journal articles were included if outcome measures reflected an assessment of the impact of a mob...

MANY people are aware that the old idea in the treatment of squinting children was to prescribe glasses as required, and then, if the appearance of the eyes did not improve, wait until at least fifteen or sixteen years of age before operating. This postponement of operation until early adult life was considered essential, so that it could be performed without general ana-sthesia, and with the c...

BACKGROUND Surgical success rate of strabismus is variable. OBJECTIVE To evaluate the outcome of monocular strabismus surgery for adults with large angle deviation. SUBJECTS AND METHODS This study was that of a retrospective interventional case series. A total of 48 consecutive adult patients with large-angle socially-noticeable strabismus underwent clinical evaluation for squint surgery. T...

of Bruch'-s membrane at the optic n-erve. Three cases of partial cross ruptures of the optic nerve are reported histologically. All three are discovered at the very insertion of the lamina elastica chorioideae. The tear was caused in all cases (traumatic, expulsive haemorrhage and haemorrhagic glaucoma) by an instantaneous, probably arterial, subiretinal bleeding. Traumatic retropulsion of the ...
