Four cases of corneal striae that developed in patients wearing PMMA contact lenses are reported. All had posterior corneal striae that had occurred in eyes with low intraocular pressures (10 mmHg), as measured by the applanation tonometer. Ocular rigidity was normal. This association of low intraocular pressure, independent of ocular rigidity, and corneal striae has not been previously emphasized. It is recommended that all patients considered for contact lenses have an applanation pressure measurement, which if found to be low (10 mmHg), the patient should be strongly advised to have follow-up examinations for as long as contact lenses are used.
