Common corneal diseases and ocular surface conditions include

• Allergic eye conditions include allergic keratoconjunctivitis and vernal keratoconjunctivtis (VKC). VKC typically affects children, often whom suffer from atopic conditions such as asthma and eczema. Appropriate management is important in these patients to prevent development of corneal scarring or keratoconus.
• Keratoconus results in an abnormally steep cornea with subsequent visual deterioration. Corneal cross-linking is a treatment that prevents the progression of keratoconus by increasing bonds between the collagen fibres in the eye. Visual rehabilitation in keratoconus also includes contact lenses and occasionally surgery.
• Dry eye occurs due to inadequate secretion or poor quality of tears. Treatments for dry eye include medical management with various eyedrops and punctal plugs, as well as surgery in advanced cases.
• Pterygia are fleshy growths on the ocular surface that are common in the Southern Hemisphere, likely due to our sun exposure. They cause itchy, irritable eyes and induce astigmatism, causing a decreased quality of vision. It is important to differentiate them from conjunctival malignancies, and management includes eyedrops and surgical removal.

Corneal conditions treatment

Treatment for corneal conditions varies based on the specific disease and its severity. Common treatment options include medications, surgical procedures, and non-surgical interventions. Prescription eye drops or oral medications are often used to reduce inflammation, treat infections, or manage symptoms. When surgical intervention is necessary, procedures like phototherapeutic keratectomy (PTK) can reshape the cornea and remove scar tissue.

In more severe cases, a corneal transplant may be required to restore vision; this involves replacing the damaged cornea with healthy tissue from a donor. If donor tissue is unavailable, an artificial cornea, known as a keratoprosthesis, may be implanted. Non-surgical interventions can also play a crucial role, particularly in cases like keratoconus, where specialized contact lenses are designed to improve vision and comfort. Each treatment plan is tailored to the individual's condition and needs, highlighting the importance of consulting with an ophthalmic surgeon for personalized care. Regular eye examinations are essential for monitoring corneal health and detecting any changes early on.
