We reviewed records from 428 consecutive patients with severe Graves' ophthalmopathy to determine early and late results after transantral orbital decompression. Optic neuropathy was present in 217 (50.7%) patients. Post-operatively, 402 (89%) of 453 eyes with preoperative visual acuity worse than 20/20 improved or remained the same. Visual field scotomas improved or resolved in 245 (91%) of 269 eyes tested pre- and postoperatively. Preoperative papilledema resolved or improved in 99 (94%) of 105 eyes, and preoperative exposure keratitis improved or resolved in 178 (92%) of 195 eyes. Average proptosis reduction was 4.7 mm. Postoperatively, new diplopia developed in 74 (64%) of 116 patients who had no diplopia before orbital decompression, although 300 patients ultimately had strabismus surgery. At late follow-up (N = 293 patients), 226 (77%) had single vision and 44 (15%) had correction with prism. Complications included sinusitis (18 patients), lower eyelid entropion (38 patients), numb lip (23 patients), cerebrospinal fluid leaks (15 patients), and one frontal lobe hematoma (one patient). The average duration of follow-up was 8.7 years. Transantral orbital decompression effectively reduces proptosis and usually corrects optic neuropathy. In other circumstances, the benefits achieved and the side effects incurred must be carefully balanced for each patient before transantral orbital decompression is considered.

Optic neuropathy affects a small proportion of patients with Graves' eye disease. It is due to optic nerve compression by enlarged extraocular muscles and can be treated by corticosteroids, irradiation or surgical orbital decompression. The current report evaluates the effectiveness of extracranial orbital decompression performed by one surgeon for optic neuropathy in Graves' eye disease. The records of 21 patients (33 orbits) undergoing extracranial orbital decompression for Graves' optic neuropathy were analysed for changes in visual acuity and colour vision and reduction in proptosis. Visual acuity and colour vision improved in all 33 eyes in the short-term postoperatively (4 weeks), but later deteriorated in 5 eyes (6.6%) of 4 patients (19%). The remainder maintained improved vision for the duration of the follow-up period (mean 22, range 3-54 months). Proptosis decreased by a mean 5.0 mm (range 1-8). Extraocular muscle imbalance and diplopia worsened in 9 21 patients (43%) and improved in 2 21 (9.5%). The patients having medial wall and floor decompressed all had worse diplopia (5 5 ), those with medial and lateral wall worsened in 4 10 cases and improved in 1 10 , and those having all three walls decompressed had no cases of worsening diplopia and 1 6 improved. All patients with symptomatic diplopia achieved binocular single vision in a useful range after one and sometimes two squint procedures. No patient lost vision as a result of the extracranial orbital decompression, but one lost vision in one eye after transfrontal decompression following failed extracranial decompression. Extracranial orbital decompression is effective in improving vision and reducing proptosis in most patients with optic neuropathy in Graves' eye disease, but induces or worsens diplopia in a high proportion of patients. The diplopia is readily correctable, and the change to decompressions that include the lateral wall may reduce the risk of postoperative diplopia.

Craniosynostosis is the premature fusion of one or more cranial sutures that may be isolated or syndromic. These children can have multiple developmental issues including speech, hearing, and vision, in addition to the aesthetic issue of an abnormally shaped skull and midfacial hypoplasia. As the aesthetic outcomes of craniofacial surgery have improved, attention has turned on the functional outcomes and visual loss is a well-known problem with these patients. In the past 15 years, a greater understanding of the causes of visual loss has developed. Factors such as amblyopia, corneal exposure, and optic neuropathy are all now looked for to prevent or reduce visual loss. Optic neuropathy is caused by craniocerebral disproportion (though to a lesser extent than originally thought), cerebral hypo perfusion, hydrocephalus, and obstructive sleep apnea. Amblyopia is due to increased incidence of strabismus, anisometropia, astigmatism, and ametropia in these cases. A comprehensive approach to managing these children's visual function allows the clinician to reduce potential visual loss in children with craniosynostoses especially the syndromic variety.

Orbital decompression is a surgical procedure aimed at increasing the orbital volume and/or decreasing the volume of the orbital fat. The indications for orbital decompression are determined in the course of thorough eye examination. An important objective of examination of a patient with thyroid eye disease (TED) is determination of inflammation activity and severity. Orbital decompression is a surgical procedure that can be performed in both the active and nonactive stages of the disease. However, the indications for the surgery in these cases are different. Optic neuropathy and severe corneal disease are threatening complications that may lead to permanent visual loss and generally occur in the presence of active orbital inflammation. If treatment with high-dose corticosteroids has proven ineffective, an urgent surgical procedure consisting of orbital decompression and, in case of involvement of the cornea, eyelid and corneal surgery has to be performed. Owing to significant progress in technology, improvement of methods and accumulated experience over the past decade, the indications for bone orbital decompression have extended compared to the time when this procedure was used only in patients with extremely severe TED. The most common complication of the orbital decompression is the development or deterioration of previously existing binocular diplopia and strabismus. In addition, other parameters may change as well, including the position of the globe, the eyelids, the angle of deviation of the eye, and intraocular pressure. Thus, bone orbital decompression is a major step of a comprehensive, often multistage, system of rehabilitation of patients with severe refractory TED.
