ABSTRACT
BACKGROUND: To propose that possible alteration or damage to the ciliary zonules during uncomplicated endoscopic cyclophotocoagulation (ECP) can cause complications in subsequent filtration surgery. CASE PRESENTATION: We present two cases with uncomplicated primary combined phacoemulsification and ECP that underwent subsequent trabeculectomy. Both cases were complicated with vitreous prolapse during the trabeculectomy procedure. We review the anatomy of the ciliary zonules and their spatial relationship with the ciliary processes targeted during ECP and propose an association between ECP, zonular damage and complications in subsequent trabeculectomy such as vitreous prolapse. CONCLUSIONS: Damage to ciliary zonules during ECP may not manifest until subsequent glaucoma filtration surgery. In patients who received prior ECP, we may consider taking preventative measures to avoid associated complications such as vitreous prolapse. Patients with known risk factors for weak zonules may consider choosing alternative intraocular pressure-lowering means.

A 11-year-old boy presented with refractory fever and dyspnoea after Nuss procedure. Massive pericardial effusion was detected on computer tomography scan performed under corticosteroid cover for his asthmatic history. With rapid clinical improvement following corticosteroids, a clinical diagnosis of post-pericardiotomy syndrome (PPS) was made. Following a course of oral prednisolone, serial blood test and echocardiogram showed gradual resolution of inflammation and pericardial effusion. This rarely-reported case serves as a poignant reminder to PPS after Nuss procedure as a cause of febrile massive pericardial effusion. Early therapeutic trial of corticosteroids may prevent clinical deterioration, and have invasive pericardial drainage avoided.
