Comfortable and Stabilizing Chin & Forehead Rest Attachment for Slit Lamp Configurations

October 10, 2024 updated by: NYU Langone Health

A Single-Center Proof Of Concept Study of a Novel Comfortable and Stabilizing Chin & Forehead Rest Attachment for Slit Lamp Configuration Devices

In this study, participants will be imaged using two Optical Coherence Tomography (OCT) devices: device N, a standard conventional OCT device with an invention (comfortable chin and forehead rest that can be adjusted to fit each individual's size) attached to the device; and device C, the standard conventional OCT device with no invention attached. The investigators will assess whether the chin and forehead rest attachment (invention) provides a more comfortable experience for patients.

Eligibility Criteria

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

Description

Inclusion Criteria:

  • Healthy volunteers; OR,
  • AMD, diabetic retinopathy, central serous chorioretinopathy, and/or glaucoma or glaucoma suspects or any other suspected eye disease

Group-Specific Inclusion Criteria:

-- There are no group-specific inclusion criteria for patients with AMD, diabetic retinopathy, and central serous chorioretinopathy.

Healthy Volunteers

  • A normal clinical ophthalmic examination.
  • Reliable VF, reproducible glaucoma hemifield tests labeled within normal limits on at least one test.
  • Good quality (adequate signal strength ≥ 6/10, without segmentation algorithm failure and motion artifacts > 1 vessel diameter) RNFL and Ganglion Cell Inner Plexiform Layer (GCIPL) OCT, within normal limits.

Primary Open Angle Glaucoma (POAG)

  • Clinical characteristics of glaucoma: optic nerve head (ONH) abnormalities: global rim thinning, rim notch, or disc hemorrhage; retinal nerve fiber layer (RNFL) defect.
  • Typical glaucomatous field loss in reliable VF, reproducible glaucoma hemifield tests labeled outside normal limits on at least two consecutive tests.
  • Good quality (adequate signal strength ≥ 6/10, without segmentation algorithm failure and motion artifacts > 1 vessel diameter) RNFL and GCIPL OCT, labeled outside normal limits with typical glaucomatous RNFL and GCIL thinning.

Normal Tension Glaucoma (NTG)

  • Identical to POAG criteria with IOP recorded at ≤ 21 mmHg at any time point.

Exclusion Criteria:

An individual who meets any of the following criteria will be excluded from participation in this study:

- Any medical treatment (e.g., chronic corticosteroid, hydroxychloroquine, chloroquine, thioridazine, canthaxanthine) or conditions that affect VF (e.g., stroke) and retinal thickness other than glaucoma.

  • Interventional Model: Crossover Assignment
  • Masking: Double

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Device C (OD-OS), then Device N (OD-OS)

Participants will be randomized to receive 1 macular scan on each eye and 1 optic nerve head (ONH) scan on each eye from two devices: device C, a standard conventional device with no attachment; and device N, the standard conventional device with the invention (comfortable chin and forehead rest that can be adjusted to fit each individual's size) attached to the device.

Participants will first be imaged using device C starting with the right eye (OD), then left eye (OS). They will then be imaged using device N, starting with OD, then OS.

Participants will first be imaged using device C starting with the left eye (OS), then right eye (OD). They will then be imaged using device N, starting with OS, then OD.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Comfort Level Rating of Device N on 0-5 Scale
Time Frame: Post-Imaging Session (Day 1)
Participants will be asked to rate how comfortable Device N was, on a scale of 0-5. Higher scores indicate higher levels of comfort.
Post-Imaging Session (Day 1)
Comfort Level Rating of Device C on 0-5 Scale
Time Frame: Post-Imaging Session (Day 1)
Participants will be asked to rate how comfortable Device C was, on a scale of 0-5. Higher scores indicate higher levels of comfort.
Post-Imaging Session (Day 1)
Percentage of Participants Who Indicate Device N Provided a More Comfortable Experience, Compared With Device C
Time Frame: Post-Imaging Session (Day 1)
Participants will be asked which device provided a more comfortable experience: Device C or Device N.
Post-Imaging Session (Day 1)

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Time Duration to Adjust for Number of Motion Artifacts Present With Device N Imaging
Time Frame: Imaging Session (Day 1)
The OCT imaging device includes an "eye tracking" feature that selects a specific location within the eye and constantly adjusts, i.e. tracks, for fine fixation adjustments that occur when a patient's eye is moving very slightly during imaging. The time to adjust for the number of motion artifacts present will be defined as the duration it takes from the moment the imager clicks "Acquire" on the device to when the progress bar is "Full."
