Ocular Surface Services
A 'dry eye' is a condition where patients suffer from irritation and discomfort in the eye because of the decreased quantity of tears or increased evaporation of tears from the eye. The symptoms are non-specific and can range from a tired or itching eye to diminished vision in severe cases. A clinical examination can help diagnose a condition of 'dry eyes' but, to be more definitive, diagnostic tests are required.
As part of our ocular surface service, patients with dry eyes undergo a detailed examination to assess the severity of the problem and other complications. Some patients may have extensive ocular surface damage. The treatment includes use of preservative-free artificial tears, autologous serum and topical immunosuppresive treatment.
Dry eyes can also be a manifestation of systemic diseases like rheumatoid arthiritis. A blood examination could help identify the disease, which can then be jointly treated by the ophthalmologist and rheumatologist. Patients who have such symptoms are advised procedures to preserve tears through implantation of silicone punctal plugs or cauterising the puncta (tear glands).
Patients suffering from ocular discomfort and dysfunction, or damaged stem cells in the eye, resulting in scarring and new blood vessel formation, have a very unstable ocular surface. For some cases, stem cell transplantation can provide a solution. Doctors at LVPEI were among the first in the world to perform this procedure, in cases of chemical injury and deep scleral ulcers.
