Investigations of Acute Closed Angle Glaucoma:
- Gonioscopy (angle between iris and cornea)
- Tonometry (IOP)
- eye exam
Investigations of Herpes Simplex Keratitis:
- clinical diagnosis
- GOLD= slit lamp with fluorescein
- viral culture, PCR, immunofluorescence assay
Investigations of Uveitis:
- slit lamp testing

- FBC, CRP
- MC&S
- CT ORBIT GOLD to help distinguish between each
Investigations of Corneal Abrasion:
- Defect seen with fluorescin staining
Investigations of Corneal Foreign Body:
- Fluorescein stain to show vertical corneal abrasions ‘ice rink’
Investigations of Globe Rupture:
- CT orbit = rule out FB
- Seidel test
Investigations of Retrobulbar Haemorrhage:
- clinical diagnosis
- CT
