The blue circle denotes the area of edema within and non-edematous cornea outside Yellow arrows point to the hydrops and pink arrows to the thinnest area. įigure 1: Composite picture showing (a) Superior DM rupture and hydrops, (b) Anterior segment optical coherence tomography (AS-OCT) image of the same, (c) AS-OCT showing the thinnest area in the inferior cornea, (d) Slit section showing DM rupture and hydrops away from the thinnest area. The possible explanation is a combination of PMD and keratoconus, as the fellow eye showed central Vogt's striae as well as features of PMD on tomography. (82.5 degrees) were opposite the axis in the control group (253.7 degrees). Also, it was away from the discretely thinnest, perilimbal non-edematous area, located inferiorly. aberrations in patients with pellucid marginal corneal degeneration. As shown in, the DM rupture and hydrops occurred unusually in the superior cornea. Our patient, an eye rubber, had these findings reversed on two counts. This could be in the central or inferotemporal cornea in keratoconus and inferior in PMD. Available from: Īcute hydrops in keratoconus or pellucid marginal degeneration (PMD) occurs due to Descemet's membrane (DM) rupture in the area of maximum thinning. To report a case of long-standing atopic dermatitis and atopic keratoconjunctivitis (AKC) with associated pellucid marginal corneal degeneration (PMCD). Unusual hydrops - Superiorly located and Descemet's membrane tear away from thin area.

If you have been diagnosed with keratoconus or pellucid marginal degeneration and would like to schedule a consultation, please use our online appointment request or call 33. Have you been diagnosed with Keratoconus or PMD? In addition, he uses only the best equipment on the market to successfully treat these eye conditions.
Jon Scott is an expert in diagnosing and treating Keratoconus and PMD. Once again, highly specialized contact lenses can be used to treat these disorders.ĭr. While some of these patients actually had undiagnosed keratoconus or pellucid marginal degeneration prior to surgery, many cases are thought to be caused by the biomechanical effects of the surgery. While the majority of patients can be treated with contact lenses, in severe cases, both disorders can lead to the need for a corneal transplant.Įven in the hands of the most skilled physicians, ectasia can be induced by refractive surgery (LASIK, PRK, RK, etc.). Pellucid marginal degeneration (PMD) is a non-inflammatory progressive ectatic disorder of the cornea.
While this doesn’t correct or reverse the condition it has been shown to significantly strengthen the cornea to keep it from getting worse. Clinical finding and treatment of a reverse PMD case of 60 years-old male with bilateral low vision, who had bilateral high astigmatism and PMD in superior quadrant of the corneas of the both eyes is presented. It involves placing vitamin-A drops in the eye and exposing it to a certain wavelength of ultraviolet light. FDA trials are currently underway for a procedure called corneal cross-linking.
