[Superior versus inferior Ahmed glaucoma valve implantation]

To compare the efficacy and safety of Ahmed Glaucoma Valve [AGV] implantation in the superior versus inferior quadrants. This prospective parallel cohort study was performed on 106 eyes of 106 patients with refractory glaucoma. Main outcome measures included intraocular pressure [IOP] and rate of complications. Other outcome measures included best-corrected visual acuity [BCVA], number of glaucoma medications and success rate [defined as at least 30% IOP reduction and 5

[Orbital echinococcosis with two different features; hydatid and alveolar cysts]

To present two patients with hydatid and alveolar cysts of the orbit and to present their clinical, imaging, pathologic and therapeutic features. Two young children from rural areas were referred for progressive proptosis. Imaging showed intraorbital cysts. They were operated on with a clinical suspicion of hydatid and alveolar cysts. Pathologic evaluation confirmed the diagnoses in both instances. Clinical findings and imaging before the operation help the diagnosis of orbital echinococcosis. Knowing the nature of these lesions can prevent surgical complications. Alveolar cysts are much more invasive than hydatid cysts and their treatment is more difficult
