Most of my patients are farmworkers exposed to high levels of pesticides, sun, and dust. A large proportion (>40%) have conjunctival injection and bilateral pterygium in each eye. What low-cost strategies are available to medically manage these eye problems? I tell patients to wear dark lenses and use lubricating eyedrops while working and recommend lavage with a sterile eye wash (e.g., Collyrium) b.i.d.
