Depending on the patient’s need, it is necessary to:

• evaluate the patient’s visual acuity

• evaluate the functionality of extraocular muscles

• evaluate lacrimal production (Schirmer’s test, BUT)

• measure ocular pressure

• evaluate the objective anatomical integrity of patient’s eyes

• evaluate functional abilities and anatomical features with instrumental examinations

• general patient history (medications and interventions)

• opthalmological anamnesis (lenses, familiarity, interventions)

• evaluation of visual acuity

• evaluation of ocular motility

• ocular pressure measurement (possible tonometric curve)

• evaluation of the anterior segment

• valuation of the ocular fundus in mydriasis (drops are placed to dilate the pupil)

• instrumental examinations

• drops of local anesthetic are instilled and then the tear film is stained with fluorescein for eye pressure measurement

• to evaluate ocular fundus midriatic drops are instilled to achieve pupil dilatation, after 2 hours the dilation regresses
• cyclopygic eye drops are instilled in children to be able to evaluate refraction as precisely as possible. The cycloplegia lasts about 24 hours
