    Editor,—We present an unusual corneal oedema which was observed following scleral indentation during a buckling procedure in a patient who had undergone successful photorefractive keratectomy (PRK), and in a second patient who presented with steroid induced high intraocular pressure following PRK.

    CASE REPORTS

    Patient 1

    A 33-year-old man underwent bilateral PRK by the Visx 20/20 excimer laser, with a 6 mm ablation zone. The refraction before the procedure was −6.00/−2.00 × 177° in the right eye and −5.00/−1.75 × 180° in the left. The corrected visual acuity was 20/20. Five months after PRK the patient’s uncorrected vision was 6/9 in both eyes. With correction of plano/−0.75 × 175° in the right eye and −0.50 in the left, his vision was 20/20 in each eye. The steroid drops were stopped a month previously.

    Six months after PRK, he noticed a shadow on the nasal field of his right eye and deterioration of vision. On admission the visual acuity in the right eye was 6/60 and the IOP 15 mm Hg. The cornea showed no pathology and there was no noticeable haze. The anterior chamber was deep and clear. Funduscopy revealed detachment …
