ABSTRACT
PURPOSE:
This study was designed to determine how patients with pellucid marginal corneal degeneration (PMCD) are managed in a tertiary corneal practice.METHODS:
A retrospective chart review of 45 patients with PMCD from a corneal referral practice was performed. Information collected from the medical records included demographic data, best-corrected visual acuity, videokeratography, contact lens use, and surgical procedures.RESULTS:
Forty-five patients (85 eyes; 30 males, 15 females) with PMCD were included in this study. They were followed-up for an average of 4.7 years (standard deviation (SD), +/-8.7). Seventy-five eyes (88.2%) were managed nonsurgically with spectacles in 31 eyes (36.4%) or contact lenses in 44 eyes (51.8%). Contact lens management was initially attempted in 51 eyes (60%); however, 7 eyes failed contact lenses. Visual acuity of 0.5 (20/40) or better was noted in 34 eyes (75.5%) after contact lens fit. Ten eyes (11.8%) underwent penetrating keratoplasty with an average postoperative follow-up of 9 years (SD, +/-8.2; 1.5-20.5). Clear grafts were present in all 10 eyes at the end of the study (average, 9 years; SD, +/-82).CONCLUSIONS:
Nonsurgical management of PMCD continues to play a predominant role in the management of this disorder. Poor best-corrected visual acuity at presentation of 0.2 (20/100) or worse and long follow-up (8 years or more) were significantly associated with surgery.
