Rhabdomyosarcoma (RMS) is a highly malignant tumor and is one of the few life-threatening diseases that present first to the ophthalmologist. It is the most common soft-tissue sarcoma of the head and neck in childhood with 10% of all cases occurring in the orbit. RMS has been reported from birth to the seventh decade, with the majority of cases presenting in early childhood. Survival has changed drastically over the years, from 30% in the 1960's to 90% presently, with the advent of new diagnostic and therapeutic modalities. The purpose of this review is to provide a general overview of primary orbital RMS derived from a literature search of material published over the last 10 years, as well as to present two representative cases of patients that have been managed at our institute.

Objective: To evaluate the influence of strabismus surgery on quality of life (QoL) in Graves' orbitopathy (GO) patients. Design: Prospective study of case series. Methods: Consecutive GO-patients who were scheduled for their first strabismus surgery were included in the study. The patients completed the GO-QoL questionnaire within 3 months before the surgery and 2-4 months after the surgery. A complete orthoptic examination, including the field of binocular single vision (BSV), was performed. Clinically relevant response (CRR) in the QoL was also evaluated. Results: In this study, 28 patients were included. The GO-QoL score for visual functioning was 46.3G24.2 before surgery and 65.7G30.5 after surgery (PZ0.009). The GO-QoL score for appearance changed from 60.6G25.9 to 69.5G24.2 (PZ0.005). After surgery, the field of BSV increased from 24.3G34.8 to 68.5G36.0 points (PZ0.000). A weak correlation was found between the field of BSV and the visual functioning score after surgery (rZ0.417; PZ0.034). CRR was found in 20 (71%) patients. Those with a CRR showed a larger field of BSV (PZ0.002) and better GO-QoL scores (PZ0.008). Conclusions: GO-QoL score increases significantly for both visual functioning and appearance after the first strabismus surgery in GO-patients, showing the highest improvement for the visual functioning questions. Both the GO-QoL and field of BSV outcomes correlate well with the CRR.

PurposeTo investigate the current practice of enucleation with or without orbital implant for retinoblastoma in countries across the world.MethodsA digital survey identifying operation techniques and material used for orbital implants after enucleation in patients with retinoblastoma.ResultsWe received a response of 58 surgeons in 32 different countries. A primary artificial implant is routinely inserted by 42 (72.4%) surgeons. Ten (17.2%) surgeons leave the socket empty, three (5.2%) decide per case. Other surgeons insert a dermis fat graft as a standard primary implant (n=1), or fill the socket in a standard secondary procedure (n=2; one uses dermis fat grafts and one artificial implants). The choice for porous implants was more frequent than for non-porous implants: 27 (58.7%) and 15 (32.6%), respectively. Both porous and non-porous implant types are used by 4 (8.7%) surgeons. Twenty-five surgeons (54.3%) insert bare implants, 11 (23.9%) use separate wrappings, eight (17.4%) use implants with prefab wrapping and two insert implants with and without wrapping depending on type of implant. Attachment of the muscles to the wrapping or implant (at various locations) is done by 31 (53.4%) surgeons. Eleven (19.0%) use a myoconjunctival technique, nine (15.5%) suture the muscles to each other and seven (12.1%) do not reattach the muscles. Measures to improve volume are implant exchange at an older age (n=4), the use of Restylane SQ (n=1) and osmotic expanders (n=1). Pegging is done by two surgeons.ConclusionNo (worldwide) consensus exists about the use of material and techniques for enucleation for the treatment of retinoblastoma. Considerations for the use of different techniques are discussed.

This meter appears to be a reliable instrument for exophthalmometry. It is the first instrument that allows for a complete parallax-free measurement.
