Abstract

After ocular contusion the ocular tension is unstable and may show considerable variation, sometimes being raised, sometimes lowered. But ocular contusion is one of the commonest causes of ocular hypotension, which may be dramatic and indeed, may be the dominant factor in determining the fate of the eye. The lowering ocular tension is slowly attaining its normal height after some variation, that this instability is frequently shared by the uninjured fellow eye. We had experienced a fall in tension-ocular hypotension as 0 mm.Hg. lasting for 13 day by ocular contusion, which was associated with mild anterior uveitis, Descemet's membrane tear, localized angle recession and hypotonic retinal changes, and shared lower ocular tension by the uninjured eye, as l4.6 mmHg. All these acute ocular hypotensive symptoms and signs were recovered 27 days after contusion, but mild Descemet's scar and angle recession with peripheral anterior synechia were remained. The final IOP in both eyes was 18.3 mmHg, and the visual acuity was 20/20.
