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...
متن کاملCorneal 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 ...
متن کاملIntacs for early pellucid marginal degeneration.
A 42-year-old man had Intacs (Addition Technology Inc.) implantation for early pellucid marginal degeneration (PMD). Two Intacs segments (0.45 mm thickness) were inserted uneventfully in the fashion typically used for low myopia correction (nasal-temporal). Eleven months after the procedure, the uncorrected visual acuity was 20/200, compared with counting fingers preoperatively, while the best ...
متن کاملcollagen cross - linking for Pellucid Marginal degeneration
Pellucid marginal degeneration (PMD) is a rare progressive condition resulting in inferior corneal thinning and astigmatism. Alongside keratoconus and keratoglobus, it is considered one of noninflammatory corneal ectasias. The focus of corneal thinning is greatest inferiorly resulting in diminished visual acuity and overall reduction in visual quality. Traditional methods of treatment or diseas...

PURPOSE To determine the efficacy of simultaneous peripheral crescentic lamellar keratoplasty (LK) and central penetrating keratoplasty (PK) for advanced pellucid marginal degeneration (PMD). DESIGN Retrospective, noncomparative, interventional case series. PARTICIPANTS Five patients with advanced PMD. METHOD Simultaneous peripheral crescentic LK and central PK followed by selective sutur...
