Why Is an Eyelid Speculum Used During an ROP Exam?

Seeing a small metal tool used on your baby’s delicate eyes can be one of the most distressing parts of a retinopathy of prematurity (ROP) exam. This tool is called a lid speculum. Because babies cannot follow instructions to keep their eyes open and look in specific directions, the speculum safely holds the eyelids apart ^[1]. This ensures the eye doctor gets a clear, quick view of the retina—the light-sensitive layer of tissue at the back of the eye—which is vital for an accurate diagnosis ^[1].

Why the Speculum Is Necessary

To properly screen for ROP, the ophthalmologist uses a specialized light and magnifying lens (a technique known as binocular indirect ophthalmoscopy) to look deep into the back of your baby’s eye ^[1].

• Overcoming Natural Reflexes: Babies naturally squeeze their eyes shut when a bright light shines in them. The speculum gently prevents blinking so the doctor can examine the eye as efficiently as possible ^[2].
• Protecting the Eye: By resting on the eyelids, the speculum is designed to hold the lids open without pressing down directly on the eyeball itself ^[1].
• Complete Visibility: It helps the ophthalmologist examine as much of the retina as possible to decide what follow-up or treatment, if any, is needed ^[2].

Note: The doctor may also use a small tool called a scleral depressor, which gently presses on the outside wall of the eye to help them see the very edges of the retina.

What to Expect Before and During the Exam

The ROP exam follows a careful process to ensure your baby is safe and as comfortable as possible:

1. Dilating Drops: About an hour before the exam, drops are placed in your baby’s eyes to widen the pupils. These drops can sometimes sting briefly.
2. Comfort Measures & Numbing Drops: Right before the exam, the care team will use anesthetic drops to numb the surface of the eye ^[3]. While these drops significantly reduce discomfort, they cannot make the exam completely painless, as the baby may still dislike the bright light or being held still.
3. Placement and Monitoring: The doctor places the speculum to hold the lids open. Because the exam can cause temporary stress, crying, or changes in heart rate and oxygen levels, the NICU team will continuously monitor your baby’s vital signs and can pause if the baby becomes too unsettled ^[2].

Depending on your baby’s medical status and NICU policy, the team may also provide a small amount of oral sucrose (a sweetened solution given by the clinical team) on a pacifier, use supportive swaddling, or allow you to provide a comforting touch ^[3].

After the Exam

While the use of a speculum is a standard, routine part of ROP screening, it is normal for your baby’s eyes to be slightly red, puffy, or teary for a few hours afterward ^[2]. Rare complications, such as small temporary spots of bleeding in the back of the eye, typically resolve on their own without lasting damage ^[4]. However, you should always notify the NICU team if you notice persistent swelling, marked redness, thick discharge, or if your baby seems to be in ongoing pain.
