A retrospective analysis of adults with strabismus was done to examine the potential risks and the possible benefits of surgical treatment and to describe the types of adult strabismus.
Eight hundred ninety-two patients were analyzed. Age at time of surgery ranged from 9 years to 89 years. The average follow up was 34 months. Major types of strabismus were grouped by their original diagnoses. The group of patients with horizontal strabismus, which usually had an onset before 9, was termed the before visual maturity (BVM) group. The group of patients with paretic or restrictive strabismus usually had the onset of strabismus after age 9 and was termed the after visual maturity (AVM) group.
Patients with adult strabismus can gain restoration of alignment, as well as binocular function. At the last postoperative visit, 74% of the BVM group were aligned within 15 prism diopters. Not only was restoration of alignment accomplished, many of them gained some degree of sensory fusion as measured by the Worth 4-Dot (W4D) or Titmus stereoacuity. Twenty-nine percent of patients with congenital esotropia had some sensory fusion. The other subtypes in the BVM group had even higher percentages of patients with postoperative stereoacuity. In the AVM group, 92% had fusion at the last postoperative visit.
The outcomes of adult strabismics in our study show that certain benefits can be gained from correction of ocular alignment. Restoration of alignment, elimination of diplopia and sensory fusion are functional benefits that can be obtained through strabismus surgery in the adult patient. It is clear that adult strabismus is more than just a cosmetic problem and treatment is worthwhile.
To evaluate and compare the preferences and attitudes of Ontario ophthalmologists and ophthalmology residents toward screencasting as an educational tool with potential use for continuing medical education (CME) events.
Eighty of 256 participants completed the survey.
The surveys were sent to participants by email, with follow-up via telephone. Study participants were urban and rural Ontario ophthalmologists, registered with the Canadian Ophthalmological Society, and University of Toronto ophthalmology residents. Pre-recorded online presentations-screencasts-were used as the main intervention. Online surveys were used to measure multiple variables evaluating the attitudes of the participants toward screencasting. This data was then used for further quantitative and qualitative analysis.
Over 95% of participants replied favourably to the introduction and future utilization of screencasting for educational purposes. Rural ophthalmologists were the most enthusiastic about future events. Practising in rural Ontario was associated with a higher interest in live broadcasts than practising in urban centres (p
This is my personal memories concerning the Nordic periodical Acta Ophthalmologica in the period 1970-88. Poul Braendstrup was scientific secretary for Acta 1950-70 and chief editor 1970-75. His many important scientific works and enormous work for Acta is described, but also personal topics are mentioned. Acta meetings in the Danish Ophthalmol Society (DOS) and in the Nordic ophtalmol. Congresses are discussed. A referee-system is established from 1976, but with political contra scientific motives. Only a few papers arrived to Acta. A catastrophe in 1978 is mentioned. The new secretary Ingelise Truberg did an enormous work for the next ten years. Erik Jørgensen (1928-90) was our printer, and from 1975 our idealistic publisher after Munksgaard. The economy became better and the number of papers of high quality increased. The relationship to the new Nordic periodical Oftalmolog was discussed in 1982.
To determine inter- and intraobserver agreement among Canadian retina specialists in their angiographic classification of choroidal neovascularization and their decision to treat with photodynamic therapy. Agreement was also determined between retina specialists and a Reading Center.
Forty retina specialists graded 24 cases of exudative age-related macular degeneration on two occasions separated by 6 months. Participants were asked to categorize the choroidal neovascularization and indicate if they would treat with photodynamic therapy. Agreement was determined for decision to treat and for interpretation of the fluorescein angiogram. Angiographic interpretation by participants was compared with that of the Reading Center.
The kappas among the 40 participants for lesion categorization and treatment decision were 0.43 (95% confidence interval: 0.36-0.52) and 0.29 (95% confidence interval: 0.18-0.42), respectively. The kappa for intraobserver agreement was 0.57 (95% confidence interval: 0.50-0.64) for lesion categorization and 0.58 (95% confidence interval: 0.43-0.74) for treatment decision. The mean percent agreement with the Reading Center for lesion categorization was 65.4%.
There was moderate interobserver agreement for choroidal neovascularization categorization and poor agreement among Canadian retina specialists for decision to treat with photodynamic therapy. There was moderate intraobserver agreement for both treatment decision and lesion categorization. There was moderate agreement between observers and the Reading Center for angiographic choroidal neovascularization categorization.
