The condition is more common in males in their 2nd to 5th decades of life. It is very important to rule out any thinning and ectatic disorders like keratoconus and PMCD before refractive surgery as upon being missed, they can lead to unwanted complications post-operatively. "Pellucid," meaning clear, signifies the clarity of the cornea despite the presence of ectasia. The term pellucid marginal degeneration was coined first by Schalaeppi in 1957 as "la dystrophie marginale inferieure pellucide de la cornee". The ectatic zone, which is 1-2 mm from the limbus, lies above the point of the maximum corneal thinning. It is characterized by a peripheral crescentic band of thinning, usually in the inferior cornea. Pellucid marginal corneal degeneration (PMCD) is a bilateral, noninflammatory, peripheral corneal thinning disease. Summarize the importance of collaboration and communication amongst the interprofessional team to enhance the care for patients with pellucid marginal corneal degeneration.Outline the treatment modalities for patients with pellucid marginal corneal degeneration.
Describe the appropriate evaluation of pellucid marginal corneal degeneration.Explain the etiology of pellucid marginal corneal degeneration.This activity reviews the evaluation and treatment of pellucid marginal corneal degeneration and highlights the role of the interprofessional team in the care of patients with this condition. To avoid ocular morbidity and permanent visual loss associated with this condition, it must be promptly diagnosed and treated. It is a relatively rare ocular condition and usually occurs in males in the 2nd to 5th decades.

Intraoperative Interface Fluid Dynamics and Clinical Outcomes for Intraoperative Optical Coherence Tomography-Assisted Descemet Stripping Automated Endothelial Keratoplasty From the Intraoperative optical coherence tomography guided corneal sweeping for removal of remnant Interface fluid during ultra-thin Descemet stripping automated endothelial keratoplasty. Rüdigerstraße 14, 70469 Stuttgart, GermanyĪn Overview of Intraoperative OCT-Assisted Lamellar Corneal Transplants: A Game Changer?. He was successfully treated with iOCT-assisted DSAEK tamponade. Hereby we report on a 49-year-old patient with pellucid marginal degeneration, who presented with spontaneous corneal perforation and secondary bleb formation due to internal fistulaįormation. The iOCT allows recognition of the corneal graft orientation and further observation of the unfolding process of the graft without the need for (DMEK), a marker was previously required. Moreover, for the correct corneal graft positioning in Descemet membrane endothelial keratoplasty
For example, the iOCT can be used for defining the cuttingĭepth of deep anterior lamellar keratoplasty (DALK) or for visualization of potential fluid in the interface in Descemet stripping automated endothelial keratoplasty (DSAEK) , , . In lamellar keratoplasty, the successful application of iOCT has already been described. Intraoperative optical coherence tomography (iOCT) is used extensively in complex anterior segment surgery, providing increased precision and thereby more safety and improved clinical Buy Article Permissions and Reprints Background
