Corneal hysteresis and corneal resistance factor in pellucid marginal degeneration
Purpose To evaluate and compare corneal hysteresis (CH) and corneal resistance factor (CRF) in pellucid marginal degeneration (PMD), keratoconus (KCN), and normal eyes using the Ocular Response Analyzer (ORA). Methods In this retrospective study, corneal biomechanical parameters were measured in patients with PMD (n = 102) and KCN (n = 202) and normal subjects (n = 208) using the ORA. Data, i...

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 ...
متن کاملCombined wedge resection and beveled penetrating relaxing incisions for the treatment of pellucid marginal corneal degeneration.
PURPOSE To evaluate a new surgical approach for the treatment of pellucid marginal corneal degeneration (PMCD). METHODS Prospective, noncomparative, interventional case series. Ten eyes of 10 consecutive patients were included in the series. Inclusion criteria were a clinical diagnosis of PMCD, topographic astigmatism >10 D, and contact lens intolerance. The patients underwent an inferior arc...
متن کاملManagement of pellucid marginal corneal degeneration with simultaneous customized photorefractive keratectomy and collagen crosslinking.
A 34-year-old woman had simultaneous photorefractive keratectomy and corneal collagen crosslinking with riboflavin-ultraviolet-A irradiation for the treatment of progressive pellucid marginal corneal degeneration in both eyes. No intraoperative or early postoperative complications occurred. Twelve months postoperatively, the uncorrected visual acuity was assessed at 20/40 in both eyes compared ...
متن کاملRefractive and corneal aberrometric changes after intracorneal ring implantation in corneas with pellucid marginal degeneration.
PURPOSE To evaluate refractive, visual, and aberrometric changes in corneas with pellucid marginal degeneration (PMD) implanted with intracorneal ring segments (ICRS) during a 6-month follow-up. DESIGN Retrospective, consecutive case series. PARTICIPANTS We included 21 consecutive eyes of 15 patients ranging in age from 21 to 73 years old and with a diagnosis of PMD. This diagnosis was made...
