Retinal Detachment

Which best describes retinal detachment?

• Separation of the neurosensory layer of the retina from the epithelium

• Thinning of the retina

• Optic nerve damage due to increased IOP

• Separation of the vitreous body from the retina

Which of these is a risk factor for retinal detachment?

• High myopia

• Previous eye surgery

• Diabetic retinopathy

• All of the above

Which of the following is NOT a symptom of retinal detachment?

• Peripheral vision loss

• Headache

• Blurred vision

• Floaters

Which management option aims to reattach the retina?

• Vitrectomy

• Scleral buckling

• Pneumatic retinopexy

• All of the above

Answer explanation

• - Scleral buckling involves using a silicone 'buckle' to put external pressure on the sclera and move the eye inwards, which reconnects the retinal layers

• - Pneumatic retinopexy involves injecting a gas bubble into the eye and positioning the patient so that the gas pushes the retinal layer back into place

Reorder the following stages of vitrectomy:

• Keyhole incisions

• Insert gas or oil into the eye

• Remove the vitreous fluid

• Repair the retinal tear

Which technique is typically used to diagnose retinal detachment?

• Fundoscopy

• Fluorescein angiography

• Ultrasound

• Magnetic resonance imaging (MRI)

What is the main cause of retinal detachment?

• Age-related degeneration

• Eye trauma

• Genetic factors

• Excessive eye strain

Retinal detachment is bilateral in what % of cases?

• 2%

• 52%

• 32%

• 12%

What is the approximate lifetime risk of having retinal detachment?

• 0.01%

• 0.1%

• 1%

• 10%
