SUPERIORITY OF SCLERAL CONTACT LENS IN PELLUCID MARGINAL DEGENERATION(CLINICAL CASE)

This article aims to highlight the advantages of using scleral contact lenses as a therapeutic approach for Pellucid Marginal Degeneration (PMD). PMD is a rare non-inflammatory corneal ectatic disorder. Due to its similar features to Keratoconus, it is harder to correctly diagnose and use effective therapeutic approaches for PMD. After a definitive diagnosis of PMD using corneal topography, we have evaluated the change in best corrected visual acuity (BCVA) both after the use of scleral contact lens and in hybrid lens. It is vital to remember that various cases of misdiagnosis may not only delay the management and treatment modalities, but also these could further result in complications, especially when the therapeutic approach between two diseases may differ.
