    Visual field defects in prematurely born patients with white matter damage of immaturity: a multiple-case study.2006In: Acta Ophthalmologica Scandinavica, ISSN 1395-3907, E-ISSN 1600-0420, Vol. 84, no 3, p. 357-362Article in journal (Refereed)
    Abstract [en]

    PURPOSE: White matter damage of immaturity may affect visual, motor and cognitive functions. This multiple-case study presents standardized perimetry results in six teenagers and young adults born prematurely with visual dysfunction due to white matter damage of immaturity of pre- or perinatal origin. METHODS: Six subjects, aged 13-25 years, born at a gestational age of 28-34 weeks, with white matter damage of immaturity documented by MRI, and optic disc appearances documented by fundus photography, were examined with manual and computerized quantitative perimetry. RESULTS: All subjects had subnormal visual field (VF) function, although the depth and extension of the VF defects differed between subjects. The inferior VF function was more deviant than the superior in all cases. The concordance between the VF defects detected with the different techniques was good, although the static computerized techniques revealed slightly more abnormality. CONCLUSION: White matter damage of immaturity may affect the VF. The lower VF is often more affected than the upper. The abnormalities can be demonstrated by both manual and computerized perimetry.

    Working with glaucoma patients - prospects for "shared care".1999In: Acta Ophthalmologica Scandinavica, ISSN 1395-3907, E-ISSN 1600-0420, Vol. 77, no 1, p. 103-106Article in journal (Refereed)
    Abstract [en]

    PURPOSE: To investigate the prospects for "shared care" by evaluating to what extent ophthalmic nurses are involved in ophthalmic care decision tasks in the management of glaucoma patients, how well prepared the nurses feel they are for these tasks and their level of satisfaction in those tasks they actually are performing. METHODS: A questionnaire was sent to the ophthalmic nurses at 13 eye clinics in Sweden. The clinics were selected to represent different parts of Sweden as well as university clinics and smaller rural clinics. RESULTS: A difference was found between clinics regarding the number of tasks independently performed by the ophthalmic nurses and a significant correlation was found between level of participation and satisfaction (p=0.008). The nurses felt prepared for (61/62) and satisfied (58/62) when performing the glaucoma management tasks, and a high and very significant correlation (r=0.96, p= 0.0001) was found between the mean preparedness and satisfaction scores for each of the 14 tasks. CONCLUSIONS: The findings in the study show that the ophthalmic nurses feel prepared for their tasks and regard their involvement in glaucoma care as subjectively satisfactory. These observations support the idea of "shared care" in glaucoma management.

    Cataract and high-pass resolution perimetry.1997In: Acta Ophthalmologica Scandinavica, ISSN 1395-3907, E-ISSN 1600-0420, Vol. 75, no 2, p. 174-7Article in journal (Refereed)
    Abstract [en]

    The present study describes the influence of cataract on high-pass resolution perimetry results. Twenty-five otherwise healthy patients were examined before and after cataract surgery. Their preoperative visual acuities ranged from 0.1 to 0.8 and their mean resolution thresholds from 3.9 to 12.3 dB. Both elevated mean thresholds and local visual fields defects were observed. In patients with low-grade cataract, i.e. preoperative visual acuity 0.3 to 0.65, the mean improvement in perimetric results after operation was approximately 1 dB. In patients with higher degrees of lens opacity, visual acuity 0.1 to 0.25, the difference between pre- and postoperative perimetry results showed a wide range, 1.4-6.2 dB. In conclusion, cataract induced different types of visual field defects. The general threshold increase due to low-grade cataract (VA > or = 0.3) could be compensated for by subtracting 1 dB from the measured value.

    Clinical experience with Latanoprost: a retrospective study of 153 patients1999In: Acta Ophthalmologica Scandinavica, ISSN 1395-3907, E-ISSN 1600-0420, Vol. 77, no 3, p. 336-339Article in journal (Refereed)
    Abstract [en]

    Purpose: To evaluate the pressure-reducing effect of latanoprost in a clinical setting. Patients and methods: Data from 153 consecutive patients with open angle glaucoma receiving latanoprost were recorded at baseline (=153), 2 weeks (n=151) and 8 to 12 months (n=89) after starting latanoprost treatment, In 82 patients (54%) latanoprost was added to ongoing treatment, Two patients terminated treatment because of side effects before the first follow-up examination, Results: 56% (84/151) of the patients showed an intraocular pressure reduction of 20% or more after 2 weeks, regardless of baseline therapy. The difference between intraocular pressure before (24.4+/-5.8 mm Hg) and after 2 weeks of latanoprost treatment (19.9+/-6.9 mm Hg) in the total group (n=151) was highly significant (p<0.0001). The pressure reduction was significantly correlated,vith the pretreatment intraocular pressure level (r=0.48, p<0.0001). In the 89 patients who could be followed for 8 to 12 months no significant upward drift in mean intraocular pressure was observed, but in fourteen patients intraocular pressure increased with 5 mm Hg or more. Thirteen patients reported side effects, five of these discontinued the treatment. Conclusion: Latanoprost is obviously an efficient pressure reducing drug which can be used in glaucoma patients as an adjunct to any ongoing therapy with the expectation of clinically relevant intraocular pressure reduction in 45-71% of the patients.

    Rarebit and frequency-doubling technology perimetry in children and young adults2005In: Acta Ophthalmologica Scandinavica, ISSN 1395-3907, E-ISSN 1600-0420, Vol. 83, no 6, p. 670-677Article in journal (Refereed)
    Abstract [en]

    PURPOSE: To describe the outcome of visual field examinations performed with rarebit (RB) and frequency-doubling technology perimetry (FDT) in children and young adults. METHODS: Twenty-one children (aged 6.5-12 years) and 30 teenagers and young adults (aged 14-20 years), participated in the study. RESULTS: Reliable RB examinations were carried out in 76% of the younger group and 90% of the older group. Corresponding values for FDT were 57% and 90-95%, respectively. The RB results were very similar to those previously obtained in adult subjects, while some subjects showed borderline values in FDT, depending on the criteria used. The RB perimetry was preferred by 88% of the examined subjects. CONCLUSIONS: Rarebit perimetry seems useful for visual field examination in children aged 7 years and over, if age-corrected normative data are established; this test was also preferred by the tested subjects. No adaptation or special instructions were needed and the children found it rather amusing.

    High-pass resolution perimetry in uncomplicated myopia1991In: Acta Ophthalmologica Scandinavica, ISSN 1395-3907, E-ISSN 1600-0420, Vol. 69, no 4, p. 516-520Article in journal (Refereed)
    Abstract [en]

    Fifteen subjects (28 eyes) with uncomplicated myopia (3-9 D) were examined using high-pass resolution and Goldmann perimetry. In the central 30 degree field a slight increase was observed in mean resolution threshold significantly correlated to the degree of myopia. In the Goldmann visual fields threshold increase was observed in the area around the blind spot in eight subjects (10 eyes). In the resolution fields only one subject (one eye) showed a corresponding abnormality.

    The effect of treatment on the results of high-pass resolution perimetry in glaucoma1994In: Acta Ophthalmologica Scandinavica, ISSN 1395-3907, E-ISSN 1600-0420, Vol. 72, p. 423-428Article in journal (Refereed)
    Abstract [en]

    In order to find out to which extent high-pass resolution perimetry would detect any changes in patients treated for glaucoma, resolution perimetry resultswere evaluated from 56 glaucoma patients and 15 untreated ocular hypertensive patients followed for 2 to 3 years. Fifty-nine of the 71 examined patients showed lower resolution thresholds, i.e. increased sensitivity after 2 years, compared to initial values. The threshold decrease was significantly larger inthe treated glaucoma patients (median 1.22 dB) than in the untreated ocular hypertensive patients (0.48 dB). The threshold decrease in the untreated ocular hypertensive group corresponds to the previously described learning effect. In 35 of the 56 treated glaucoma patients the thresholds improved more than 0.84 dB, the upper confidence limit in the untreated group, which may indicate a beneficial effect of antiglaucoma therapy in these patients.The threshold change was unrelated to initial resolution threshold and cannot be explained by a 'sorting' effect. The observations in the current study using resolution perimetry indicate that improved visual function can be demonstrated in many patients treated for early glaucoma, at least during thefirst 2 years of treatment.

    Management of ocular hypertension and open-angle glaucoma: clinical practice and computer-assisted decision-making1997In: Acta Ophthalmologica Scandinavica, ISSN 1395-3907, E-ISSN 1600-0420, Vol. 75, no 6, p. 700-704Article in journal (Refereed)
    Abstract [en]

    Purpose: To evaluate the feasibility of computerized decision support in the management of patients with open angle glaucoma or ocularhypertension. Method: Based on a Swedish consensus document a computer program was developed, which provided one of 25 different recommendations for appropriate action. In 373 patient visits to seven different eye clinics, the program's recommendations were compared to the actual decisions made by the responsible ophthalmologists. Results: Notable differences were observed between the clinics' managementstrategies, especially regarding follow-up frequency and start or increase of antiglaucoma treatment. The program's recommendations conformed with the clinical decisions in 23 to 92% of the cases when a standard management strategy was simulated. The concordance increased to 93 to 100%, when policy differences between the clinics were taken into account. Conclusion: Clinical decision-making in the management of patients with ocular hypertension or open angle glaucoma can be implemented in a computer program. The optimum management protocol remains to be defined.
