Corneal Hydrops in Pellucid Marginal Degeneration: A Case Series.

Purpose: To report an unusual presentation of pellucid marginal degeneration (PMD) and its management by using air injection and tension sutures.

Case Report: We report 2 cases with a history of acute pain and loss of vision. Examination revealed hydrops at the 6-9 o'clock meridian with Descemet's membrane detachment and tear at the same area and advanced PMD in the other eye.

Discussion: Air injection with suturing to treat the hydrops in PMD and crescentic excision with lamellar grafting instead of lamellar keratoplasty lead to better results than conservative management.

Conclusion: Corneal hydrops and perforation in patients with PMD is a rare presentation and can be managed by tension sutures and air injection.
