The keratoconus incidence was found to be 11% in first-degree relatives of patients with keratoconus as opposed to a reported incidence of keratoconus of 0.05% in the general population. In first-degree relatives of patients with keratoconus who did not have a topographic keratoconus pattern, abnormal corneal topographic values were detected. The asymptomatic relatives of patients with keratoconus should undergo a thorough preoperative analysis for subtle topographic abnormalities before any keratorefractive surgery.

Pingueculae display hyperautofluorescence in AF imaging. The real size of pingueculae may be estimated by its AF characteristics, which is mostly larger than the visible lesion.

Analysis of RNFL thickness in eyes with focal glaucomatous visual field defects showed good structural and functional correlation with OCT. OCT contributes to the identification of focal defects in the RNFL of glaucoma patients.

A 31-year-old woman who presented with photophobia was found to have bilateral corneal and conjunctival crystal deposition. Ocular cystinosis was diagnosed upon observation of typical crystals and lack of systemic involvement. In vivo confocal microscopy confirmed crystal deposition of the corneas and conjunctivae bilaterally. Optical coherence tomography showed stromal hyper-reflectivity due to crystals within the corneal stroma. Transmission electron microscopy of the conjunctiva demonstrated pathognomonic intralysosomal cystine crystals inside fibroblasts and macrophages. Clinicopathological characteristics of ocular cystinosis are well described by this exceptional case.

A patient with anterior chamber gas bubbles after LASIK flap formation with femtosecond laser is presented. A 33-year-old male patient had LASIK for myopia with corneal flap formation with IntraLase FS30 femtosecond laser. In the right eye, air bubbles were observed in anterior chamber after successful flap formation. Laser correction was completed successfully, by Wavelight Allegretto Wave Eye-Q excimer laser, without eye-tracker. Visante anterior segment optical coherence tomography imaging displayed that the pocket extended to limbal area, with stromal bed thickness of >600 microm at that area. We propose as possible causes of the air bubbles scattering of femtosecond laser beam producing direct photodissociation of aqueous humor, or direct cavitation effect in aqueous humor due to rapid pressure changes in corneal lamellar interface during the femtosecond laser procedure. Other causes such as migration of intrastromal bubbles through peripheral corneal stroma and trabecular meshwork, or through posterior stroma and endothelium, seem to be unlikely.
