Data from the Collaborative Longitudinal Evaluation of Keratoconus (CLEK) Study are a useful resource for providing evidence-based information to patients with keratoconus.

Clinical evaluation of the optic nerve head and retinal nerve fiber layer is essential for diagnosing glaucomatous damage and progression. A set of five rules outlines a systematic approach to the examination.

Acanthamoeba keratitis can be challenging to diagnose, but early detection is critical to prevent severe vision loss. High index of suspicion and use of confocal microscopy are important tools for evaluating patients with keratitis of unexplained origin.

Dry eye can compromise comfort of contact lens wear. Maintaining patients in their lenses requires management of the dry eye disease and proper lens fitting. Good selection of lens materials and care solutions are important, as is patient compliance with recommendations on lens wear and care.

New spectral-domain optical coherence tomography technology allows visualization of the junction of the inner and outer segments of the photoreceptors. Assessment of the photoreceptor integrity line in eyes with and without disorders of the outer retina indicates it is a useful biomarker for photoreceptor impairment.
