purpose: to compare visual and refractive outcomes as well as graft survival after penetrating keratoplasty (pk) in keratoconic patients with or without acute hydrops. methods: in this comparative interventional case series, 14 eyes of 14 keratoconic patients with acute hydrops (group 1) and 37 eyes of 37 keratoconic patients with no history of acute hydrops (group 2) underwent pk. visual acuit...

purpose: to present two patients with acute corneal hydrops, superimposed with infectious keratitis using topical steroids. patients and findings: the first case was a 44-year-old man with acute corneal hydrops in his left eye which was on topical steroids for one week. visual acuity was hand motion at presentation and there was a large epithelial defect with stromal infiltration and corneal ed...

PURPOSE To summarize the current concepts and recent literature regarding the epidemiology, pathogenesis, imaging modalities, and treatment of acute hydrops in keratoconus. DESIGN Perspective. METHODS Review and synthesis of selected literature, with interpretation and perspective. RESULTS Acute corneal hydrops is an incompletely understood complication of keratoconus, characterized by ma...

purpose : to report a case with history of penetrating keratoplasty (pk) for keratoconus that developed acute hydrops in the recipient and donor cornea methods : a 46-year-old man, with history of bilateral keratoconus, who had undergone corneal transplantation in his left eye, presented with complaints of sudden visual reduction, photophobia, redness and pain of the left eye. results : review ...

AIM To investigate the clinical and diagnostic findings of a patient with acute hydrops using anterior segment optical coherence tomography (AS-OCT). METHODS The AS-OCT findings of a 43-year-old patient with acute hydrops associated with keratoconus were examined. At the initial examination and during follow-up, evaluation of the anterior segment was performed. RESULTS The patient presented...

a 53 year-old woman presented with corneal edema 25 years after uneventful penetrating keratoplasty for keratoconus. she was initially misdiagnosed with acute endothelial rejection; however by observation of descemet’s membrane detachment, a diagnosis of late onset corneal hydrops following corneal transplantation was made. this is a rare complication which may occur many years after penetratin...

This case series describes acute corneal hydrops in three young horses. Due to similarities the clinical appearance and progression of disease with that which is reported humans cats hydrops, traumatic Descemet’s membrane rupture was suspected be underlying aetiology these equine cases. The horses presented severe oedema intrastromal bullae formation anterior bulging contour. Focal posterior ch...

The classical guinea pig model for Meniere's disease, in which endolymphatic hydrops was achieved by destruction of the endolymphatic sac and obliteration of the endolymphatic duct, is a non-physiological profound model with shortcomings in relation to Meniere's disease as seen in patients. We developed a more subtle animal model; the two-phase endolymphatic hydrops. This model is based on a co...
