Screening of forme fruste keratoconus with the ocular response analyzer.
PURPOSE To evaluate the performance of the Ocular Response Analyzer (ORA) in the screening of forme fruste keratoconus (FFKc). METHODS A retrospective comparative study was conducted involving 180 eyes. ORA preoperative data were analyzed for 125 normal control eyes (64 patients) undergoing laser in situ keratomileusis (LASIK) without corneal ectasia after 24 months of follow-up and 55 case e...
متن کاملTopographic and tomographic properties of forme fruste keratoconus corneas.
PURPOSE To investigate the efficacy of topography and tomography indices combined in discriminant functions to detect mild ectatic corneas. METHODS The authors retrospectively reviewed the data of 143 eyes separated into three groups by the Corneal Navigator OPD scanning system (Nidek, Gamagori, Japan): normal (N; LASIK surgery with a 2-year follow-up; n = 72), forme fruste keratoconus (N top...
متن کاملEye Rubbing as a Possible Cause of Clinical Progressive Keratoconus in a Forme Fruste Keratoconic Family
We report a case of a 21-year-old male patient who underwent corneal cross-linking (CXL) due to bilateral progressive keratoconus. Topographical screening of his family members was performed for the detection of possible familial keratoconus and showed abnormal topographical patterns resembling to Forme Fruste Keratoconus (FFK) in all the members of his family. The reported keratoconic patient ...
متن کاملEvaluation of total and corneal wavefront high order aberrations for the detection of forme fruste keratoconus.
PURPOSE To investigate the application of anterior corneal and ocular aberrations in detecting mildly ectatic corneas. METHODS This study retrospectively reviewed the data of 220 eyes separated into three groups by the NIDEK Corneal Navigator System automated corneal classification software: normal (N) (n = 123); forme fruste keratoconus (N topography with contralateral KC) (n = 34); and KC (...
متن کاملForme Fruste Keratoconus Imaging and Validation via Novel Multi-Spot Reflection Topography
BACKGROUND/AIMS This case report aims to evaluate safety, efficacy and applicability of anterior surface imaging in a patient with forme fruste keratoconus (FFKC) based on a novel multi-spot, multicolor light-emitting-diode (LED) tear film-reflection imaging technology. CASE DESCRIPTION A 45-year-old male patient, clinically diagnosed with FFKC, with highly asymmetric manifestation between hi...
