Scleral necrosis and infection are serious late complications of pterygium treatment and are difficult to manage. We describe a 70-year-old Chinese male who presented with scleral necrosis and Pseudomonas aeruginosa infection 15 years after the excision of a pterygium. The infection was treated early and aggressively with intensive topical and intravenous antibiotics and the thin necrotic sclera was reinforced with a donor scleral patch graft when the scleral infection was clinically controlled. The integrity of the globe was maintained by a thin layer of sclera anterior to the graft after the graft gradually shrunk in size and retracted posteriorly. The eye was saved from possible scleral perforation and endophthalmitis. This case is reported to highlight the importance of early aggressive treatment of infection and the value of prophylactic repair of scleral necrosis in the management of these late complications of pterygium treatment.

Permanent visual loss is a well established major sequela of idiopathic intracranial hypertension (IIH). It is often insidious and frequently unnoticed by patients with IIH. It is vital to monitor these patients with serial perimetric and visual acuity tests because visual loss can be halted and occasionally reversed if treatment is begun early. We report a case of IIH with an empty sella turcica and polycystic ovary syndrome who developed visual field loss over ten years. This report illustrates the importance of close ophthalmic monitoring and detailed neurological and endocrinological evaluation to prevent complications in such patients.

<p>INTRODUCTIONThe use of adjuvant temozolomide (TMZ) in patients managed with surgery and adjuvant radiation therapy (RT) for glioblastoma multiforme (GBM) has been demonstrated to improve median and 2-year survival in a recent large international multicentre study. To confirm this result in routine clinical practice, an audit of the management and outcome of patients with GBM at The Cancer Institute Radiation Oncology was performed.p><p>MATERIALS AND METHODSAll patients with GBM managed radically at The Cancer Institute Radiation Oncology from May 2002 to 2006 were entered into a prospective database. Patient, tumour and treatment factors were analysed for association with the outcome of median survival (MS). Survival was calculated using the Kaplan-Meier technique and correlation was assessed using Cox proportional hazards regression.p><p>RESULTSForty-one patients with GBM were managed with radical intent over the 4- year period. The median age was 54 years and 66% were Eastern Cooperative Oncology Group (ECOG) 0-1 performance status. Macroscopic, subtotal and biopsy alone procedures were performed in 61%, 29% and 10% of patients, respectively. The median time from surgery to RT was 26 days. Adjuvant TMZ was used in 44% of patients (n = 18). The MS of the total group was 13.6 months, with a 24% 2-year overall survival. The use of TMZ was associated with improved MS (19.6 versus 12.8 months; P = 0.035) and improved 2-year survival (43% versus 0%). A requirement of dexamethasone dose greater than 4 mg at the end of RT (P = 0.012) was associated with worse survival, but there was no association of MS with age, ECOG, tumour size or extent of surgery.p><p>CONCLUSIONThe median and 2-year survival outcomes are comparable to the results of the European Multicentre Study and justify the continued use of TMZ in routine clinical practice.p>
