Pinguecula and pterygium are two eye conditions which are often referred to as “the callous on the eye”. They appear as white-yellowish patch next to the cornea. The blood vessels of the eyes are irritated. Prolonged exposure to infrared and ultraviolet radiation from sunlight is one of the main causes of these lesions.
Certain environmental factors like wind and dust may also cause these eye lesions. People who engage in outdoor activities such as gardening and golfing are more susceptible. Even individuals who work outside such as fishermen and farmers are prone to these eye growths.
Symptoms of Pinguecula and Pterygium
Most of the time a bump appears without exhibiting any other symptoms. Most people may feel that cancer is growing or a foreign body is trapped in the eye. Therefore, you should consult an ophthalmologist.
Treatment of Pinguecula and Pterygium
Generally, for most people, a conservative approach is recommended. To relieve the sensation of a foreign particle, artificial tears may provide relief. Sometimes a mild optical decongestant is prescribed when a lesion becomes mildly inflamed.
If you want to remove a pinguecula or pterygium, surgery is the only option. But sometimes the results can be disappointing. The rate of recurrence is somewhere around 50-60 %. Surgery is recommended only when the pinguecula or pterygium is causing a major problem. Usually, the surgery is performed as an outpatient procedure.
Mostly, it typically takes around a few weeks for complete healing. The patients are asked to regularly apply topical ointments or eye drops. The eye may appear bloodshot and slightly swollen in the early phase of healing. Gradually, the surgical site improves in appearance and comfort.
