2024年9月25日 · Corneal staining isn’t a disease, it’s a sign of abrasions to your cornea, the outer surface tissue of your eyes. Abrasions can have different causes, including wearing contact lenses or if...

2000年2月1日 · Corneal staining is the most frequently observed contact lens related tissue complication. Its prevalence in rigid gas permeable (RGP) and soft contact lens wearers is about 60 percent. The most common etiologic categories for contact lens related staining are drying, mechanical, toxic or allergic, physiologic and infectious.

2011年4月18日 · Conjunctival staining is useful for evaluating both dry eye patients and contact lens wearers. In contact lens patients, circumlimbal staining observed with lissamine green may be an indicator of contact lens induced conjunctival staining (CLICS)—indicating that the lens is too tight or has a sharp edge design.

2010年3月1日 · A superior epithelial arcuate lesion (SEAL) is a soft contact lens phenomenon that may cause affected contact lens patients to complain of irritation or foreign body sensation. The typical presentation is an arcuate area of corneal staining that can run from the 10 o'clock to the 2 o'clock position within 1mm of the limbus.

2023年10月30日 · The extent and pattern of staining provide valuable insights into the underlying causes, such as dry eye syndrome, contact lens-related problems, or ocular allergies. Moreover, corneal staining can manifest as discomfort, redness, or visual disturbances for the affected individual, making it a significant concern both diagnostically and in ...

Our three diverse areas of clinical research, biosciences and education work together in support of our mission to improve global eye health and vision.

2012年3月8日 · There are a large number of reasons for corneal staining caused by lens wear including hypoxia, deposits, care products, lens fit, lens surface or edge irregularities, foreign bodies, and tear film disruption. The integrity of the epithelium should be assessed carefully at each contact lens aftercare visit. Attention should be paid to the ...

2007年9月1日 · It's critical, therefore, to understand how contact lens solution products interact with all of the different silicone hydrogel materials and that practitioners receive scientifically valid guidance on which combinations are the most efficacious and benign.

1. What slit lamp technique would you use to examine this patient for corneal staining? A. Narrow beam. B. Low illumination. C. White light. D. Fluorescein and cobalt blue light. 2. What is the best time of day to examine patients for solution-induced corneal staining? A. Immediately after lens insertion. B. 2-4 hours after insertion. C. 6-8 ...
