Cornea and ocular surface conditions
Ocular surface care includes the cornea, conjunctiva, eyelids, tear film, and meibomian glands. Problems in these structures can overlap, so the examination looks for infection, inflammation, tear film instability, eyelid disease, allergy, contact lens complications, and corneal surface irregularity.
Red eye, keratitis and irritation
Keratitis means inflammation of the cornea. It can be related to dryness, infection, contact lens wear, trauma, exposure, allergy, or inflammatory disease. Eye pain, light sensitivity, reduced vision, discharge, or contact lens-related redness should be assessed promptly.
Dry eye and tear film instability
Dry eye symptoms may come from tear evaporation, aqueous deficiency, meibomian gland dysfunction, inflammation, or a mixed pattern. Evaluation may include tear film assessment, eyelid margin review, gland assessment, and ocular surface staining.
Blepharitis and meibomian gland dysfunction
Inflammation around the eyelids and blocked oil glands can cause burning, crusting, redness, unstable vision, and recurrent irritation. Treatment planning depends on whether lid inflammation, gland blockage, tear instability, or associated dry eye is driving symptoms.
Corneal shape and surface irregularity
Corneal topography can help map the front surface of the eye when symptoms or examination suggest irregular astigmatism, corneal surface change, keratoconus screening needs, or visually significant tear film instability.
Contact lens-related symptoms
Contact lens discomfort, redness, pain, or light sensitivity needs careful assessment of the cornea and ocular surface. In some cases lenses should be stopped until the eye has been examined and the cause is clear.
