A 15 years old girl presented to us with diminution of vision within 4 days of onset. The child underwent relevant investigations and a diagnosis of optic disc pit maculopathy (OPD-M) was made. The parents refused surgical intervention and so we started the child on oral acetazolamide. She was kept under repeated and close follow-ups. We noticed rapid resolution of optic disc pit maculopathy within 2 months of presentation with complete visual recovery. Oral acetazolamide was tapered during the course of 2 months. We conclude that although numerous treatment modalities have been described for optic disc pit maculopathy, a trial of oral acetazolamide can be offered in cases of optic disc pit maculopathy in paediatric patients.

Being handicapped cycle dependent may cause limitations in functioning, i.e. impede functions of daily living and/or participation. To improve ambulation, the Foot Steered user combination can be optimized at three levels. On the level of the user one can optimize physical capacity and technique by training. The second level focuses on the Foot steered tricycle user interface, i.e. the interaction between the human system and the geometry of both the seating orientation and steering mechanism, aiming for a higher efficiency. This operation gives us a better ratio of internal power from the user to the external power required for drive. Finally, at the level of the Tricycle the focus lies on minimizing power loss of the Tricycle-User by reducing frictional forces and optimizing the vehicle mechanics. To advance handicapped cycle design, better insight in the working mechanisms of our biological system in combination with a mechanical extension, such as the handicapped cycle is necessary.
