Do All People With High IOP Get Glaucoma?
Ocular hypertension is a condition where the IOP is consistently over 21 mmHg but there is no other evidence of glaucoma. In other words, although the IOP is high, the optic disc shows no features of glaucoma and there is no glaucoma related vision damage in the visual field test.
People with ocular hypertension are at increased risk of developing glaucoma and this risk will increase according to the presence of other risk factors:
• Positive family history of glaucoma (having a parent or sibling with glaucoma)
• 'Suspicious' optic disc appearance
• Thin central corneal thickness
• IOP greater than 30 mmHg
