The role of an optician in the eye protection activities.

To describe the role of an ophthalmic optician in the eye protection activities of occupational health care this paper concerns the basic training of the opticians in Finland, the optoergonomics courses, the importance of eye protection activities, and the role of an optician in the protection of eyes and vision at work. It is concluded that it is important to correct the refraction of the employees, because the workers with poor vision have more industrial accidents than those with normal vision. A programme created to increase the use of eye protectors indicates the role of the optician in eye protection activities.

Practical principles of the prevention of occupational eye injuries.

The prevention of eye accidents is one part in the whole field of occupational safety which can be carried out in the most clear-cut manner. Solution patterns are easily mapped out and applied to use. Eye accidents occur mostly in the metal industry but are spreading through the whole field of industry from year to year. The principles of the prevention of eye accidents can be applied as an example for many other branches of occupational safety and thus models of functions created by the enterprise for sight protection can be projected to other prevention points.

Contact lenses and the work environment.

Controversial opinions have been presented about the use of contact lenses in industrial environments. Work environments contain few obstacles to the use of contact lenses, but many occupations are associated with the risk of excessive difficulties, spoilation , irritation, or complications. From the radiant energy the shorter (280 nm) ultraviolet (UV) wavelengths and the longer (1300 nm) infra-red (IR) wavelengths are absorbed by contact lenses, the absorption increases their temperature and may cause corneal complications. Protective glasses, however, absorb more than 99.5% of the UV and IR energy and thus provide sufficient protection for contact lens wearers exposed to UV or IR radiation. The advantages and risks of contact lenses in industrial work are discussed.

Permanent results of pleoptic treatment.

The value of pleoptic treatment was assessed by a long-term follow-up of patients treated 15-22 years ago, employing a questionnaire sent to 232 patients and a clinical examination of a sample of 44 of these. Answers were received from 157 persons with different occupations and educational levels who were fairly representative of the population of Northern Finland as a whole. The treatment was considered beneficial by 62% of these. The primary improvement in the mean visual acuity (VA) from 0.33 to 0.86 among the 44 persons examined proved to be partly transitory, the final mean value being 0.61. The poorest results were found in the combined strabismic and anisometropic amblyopia group. The final VA correlated positively with the initial VA and negatively with age at the time of treatment. Binocular single vision improved the prognosis. Altogether 1/4 of the patients achieved a VA of 1.0 or better, about one half experienced no permanent increase in VA and the remainder were distributed evenly between these two extremes.

Work-related penetrating eye injuries.

A review of all penetrating eye injuries treated at the Manchester Royal Eye Hospital over 5 years (January 1st 1982 to December 31st 1986) was undertaken. There were 258 penetrating eye injuries of which 69 (26.7%) were due to work-related accidents. All were men and 52 (75.4%) of them were under the age of 40 years. Hammering and chiselling were the commonest activities at the time of the injury and accounted for 25 cases (36.2%). Thirty-six patient (52.1%) had intraocular foreign bodies. Thirty-six patients (52.1%) achieved a good visual result (6/12 or better) and 9 had no perception of light, 7 of whom had enucleations. The period of inpatient treatment ranged from 1 to 26 days. From the analysis of the activities at the time of the injury, 61 injuries (88.4%) may be considered to be preventable with appropriate eye protection.

Filter goggles imitating dark adaptation for measurement of visual readaptation after flash exposure.

The effect of red pass goggles (cut off wavelength = 650 nm) imitating dark adaptation on measurement of visual readaptation after flash exposure was investigated in humans. The results showed that there is no statistically significant difference between visual readaptation time measured with ordinary dark adaptation and that with goggles for adaptation. No statistically significant difference was found between females and males. It is suggested that red pass goggles can be practicably used to simulate dark adaptation in measuring visual readaptation time. Visual readaptation time was measured as the interval between the triggering of a green flash and the reappearance of optokinetic nystagmus. Optokinetic nystagmus was induced by a moving vertical grating and recorded by DC EOG.

Eye injuries and the dentist.

The risk of damage to the eyes of the patient, the dentist and his assistant should be recognized. Protection can be achieved by the wearing of specially designed spectacles using CR 39 plastic tinted lenses. Contact lenses should be removed by patients who are to undergo general anaesthesia.

Utilization of personal protective equipment in general dental practice.

The principles of universal precautions are central to infection control. These principles form the basis or current guidelines for the use of personal protective equipment (PPE) in dental practice. This study, which examined the patterns of use of PPE in general dental practice, was based on a postal survey of 250 dentists in Brisbane (41 per cent of the total private general practitioners in the region). Routine use of PPE was commonplace (gloves, 84-6 per cent; masks, 55.7 per cent; eyewear, 77.6 per cent), but complete compliance with current acommendations for glove handling and hand care had not been achieved. Potential problem areas in terms of attitudes to PPE were identified, as were inconsistencies in the use of PPE in both clinical and non-clinical settings. These findings emphasize the need for further educational campaigns in practical infection control measures.

Utilisation of personal protective equipment in dental practice.

OBJECTIVE: To investigate personal protective equipment such as gloves, mask and protective eye wear used in dental practice in Turkey. DESIGN: An e-mail based self-report questionnaire was sent to dentists during 2002. PARTICIPANTS: Dentists in Turkey. RESULTS: 574 dentists aged 22-69 years responded. Thirty-six questionnaires were not included in the results. The results of the present study indicate that a high proportion of younger dentist respondents are using personal protective equipment in accordance with guidelines. More dentists use personal protective equipment for high-risk patients. The percentage of dentists using protective eyewear was low considering the general recommendations. CONCLUSION: The present study indicated that gloves and masks are used by a high proportion of the respondents. Further education may be appropriate in protective eyewear.

Basic infection control procedures in dental practice in Khartoum-Sudan.

OBJECTIVES: To survey the infection control procedures used by dental practitioners in Khartoum, Sudan. METHODS: Questionnaires were distributed to150 randomly sampled dentists practising in Khartoum state. Each questionnaire comprised 17 questions about basic infection control procedures. RESULTS: A 100% response rate to the questionnaire showed that 92% of dentists routinely wore gloves when treating patients, 50% face masks, 61% a gown and 14.7% protective eye wear. Furthermore 52% of the practitioners had been immunised against Hepatitis B. The majority of practitioners (72%) used dry heat as their method of instrument sterilisation, 22% used an autoclave, 2% used boiling water and the remainder used chemical sterilisation. Safe disposal of clinical waste was undertaken by only 23% of dentists although 47% of practitioners stored sharp items in closed containers. All respondents used disposable dental needles, but only a few used other disposable items. There was a significant difference in the implementation of cross infection control procedures between salaried and private dental practitioners, especially with regard to handpiece sterilisation, use of disposables, the wearing of face masks and the availability of additional sets of instruments. CONCLUSION: There is a clear need to improve the existing situation particularly with regard to immunisation of dentists against Hepatitis B, the safe disposal of clinical waste and instrument sterilisation in Khartoum.

Physical factors determining the utility of radiation safety glasses.

Ten types of lenses were tested for their radiation protection properties in three experimental circumstances: (a) Their good geometry (scatter free) attenuation was determined as a function of HVL in a direct x-ray beam. (b) Their dose reducing properties were determined under simulated clinical fluoroscopic conditions, using both ion chambers and thermoluminescent dosimeters (TLD's) while the lenses, mounted in frames, were worn by a head phantom. The head was oriented in four different directions to simulate clinical conditions in a fluoroscopic room. (c) Their dose reducing properties were measured with TLD's while the glasses were worn by radiologists during clinical fluoroscopic procedures. Although several of the lenses could attenuate a direct x-ray beam several thousand times, none of the glasses offer more than a factor of 8 reduction in eye exposure when the glasses are worn during fluoroscopy. This is attributed to backscatter from the fluoroscopist's head and deficient lateral shielding. Some of the glasses may even be causing an increase in eye exposure when the TV monitor is located 90 degrees or more from the patient.

Why is compliance with occlusion therapy for amblyopia so hard? A qualitative study.

OBJECTIVE: To explore parents' perceptions and experiences of occlusion (patching) therapy for treatment of amblyopia in children. METHODS: Qualitative study involving semistructured interviews with 25 families of a child with amblyopia being treated at a specialist clinic. Interviews were tape recorded and transcribed verbatim. Data analysis was based on the constant comparative method, assisted by qualitative analysis software. RESULTS: Parents of children prescribed patching treatment found themselves obliged to manage the treatment. This involved dilemmas and tensions, with many parents describing children's distress, particularly in the early stages of patching treatment. Parents were highly sensitive to the credibility of the treatment, but were sometimes confused by information given in the clinic or did not see clinic staff as authoritative. There was evidence that parents were likely to abandon or modify treatment if no improvement could be detected or if the child continued to suffer socially or educationally. Parents described a range of strategies for facilitating patching, including explanation; normalisation; rewards; customising the patch; establishing a routine; and enlisting the help of others. Whatever their practices in relation to patching, parents were keen to defend their behaviour as that of a "good parent". CONCLUSIONS: Interventions that aim to improve compliance should take account of the difficulties and tensions experienced by parents, rather than simply treating non-compliance as resulting from information deficits. Practical support that builds on strategies described by parents is likely to be of benefit.

Light transmission of phototherapy eyeshields.

Twelve types of phototherapy eyeshields showed peak light transmission of less than 0.1%, and none transmitted greater than 0.04% light in the 460 nm spectral region. Commercial eyeshields offered no advantage over locally made ones. The choice of shield may be less important than how it is secured over the infant's eyes.

Light transmission measurements and phototherapy eyepatches.

The transmission characteristics of phototherapy eyeshields have been measured under conditions that mimic the clinical situation. Peak transmission (less than 10%) was detected at 700 nm for the poorest patch tested and less than 2% for either of the other patches examined. The optics of measurement systems are considered with reference both to this and previous studies of light transmission through eyepatches. The simplicity and effectiveness with which eyepatches can be secured may be as important as their transmission characteristics.
