Prescribing practices for treating amblyopia with occlusion therapy varied considerably among orthoptists, an objective survey in Europe found.
Prof. Dr. Huibert J. Simonsz and colleagues conducted the survey, which was completed by 177 Dutch and 227 German orthoptists.
Respondents were presented with five case examples of amblyopic children and asked to give their prescriptions for hours or days of occlusion. Responses were then classified into five regimens ranging from full-time occlusion to no occlusion. Respondents were ranked according to how their prescription compared against the average.
The authors found that the number of hours of occlusion varied widely per case and per occlusion regimen. Treatments were neither consistently strict nor consistently lenient, the authors said.
The study is published in Graefe’s Archives for Clinical and Experimental Ophthalmology.
