Indications for Use

This device is intended to assist in the detection and management of aniseikonia.

Device Story

The Aniseikonia Inspector is a diagnostic tool for detecting and quantifying aniseikonia. It utilizes 'direct comparison eikonometry,' where a patient views two different images—one for each eye—separated by red and green filters. The images are displayed on a computer screen. The patient determines if a size imbalance exists between the two images. Using a computer peripheral (keyboard), the patient adjusts the size of one image until both are perceived as equal. The magnitude of the adjustment required to achieve perceived equality serves as the measure of the patient's aniseikonia. The device is intended for use by clinicians to inform the prescription of corrective lenses. It benefits patients by providing a quantitative basis for managing binocular vision size differences.

Clinical Evidence

No clinical data provided; bench testing only.

Technological Characteristics

The device consists of software running on a computer system, utilizing a display screen and red/green filters for binocular image separation. It operates via manual user input (keyboard) to adjust image size parameters. No specific materials or connectivity standards are detailed.

Indications for Use

Indicated for patients requiring detection and quantification of aniseikonia, a binocular vision condition characterized by a relative difference in the size and/or shape of the ocular images of the two eyes, to facilitate the calculation of corrective prescriptions (glasses or contact lenses).

Regulatory Classification

Identification

A haploscope is an AC-powered device that consists of two movable viewing tubes, each containing a slide carrier, a low-intensity light source for the illumination of the slides, and a high-intensity light source for creating afterimages. The device is intended to measure strabismus (eye muscle imbalance), to assess binocular vision (use of both eyes to see), and to treat suppression and amblyopia (dimness of vision without any apparent disease of the eye).

### 2. Device name The Aniseikonia Inspector

#### 3. Substantial equivalence

Substantial Cquirvationer aniseikonia.

#### 4. Description of the device

The device is based on an old technique called 'direct comparison eikonometry'. I.e. the two eyes are offered a different image and the subject needs to determine if there is a size imbalance between the two images. If there is an imbalance in size, the size 16 a one of the images is changed until the subject perceives the two images as equal in size. The extent in which one of the images needed to be changed in size is a measure for the amount of aniseikonia of the subject.

In The Aniseikonia Inspector the separation between the two eyes is accomplished by holding a red and a green filter in front of the eyes. The images are created on a computer screen and they can be altered by using a computer periheral such as the keyboard.

#### 5. Intended use

The device is designed to detect and quantify the amount of aniseikonia of a patient. Aniseikonia is defined as a condition of binocular vision where there is a relative difference in the size and/or shape of the ocular image of the two eyes. If a significant amount of aniseikonia is detected in a patient, a new prescription (contact lenses and/or glasses) can be calculated to reduce the amount of aniseikonia.
