## What is polaHelp?

**1.** As an optometrist or ophthalmologist, you often encounter situations where the patient cannot clearly express how they perceive the Polatest images. This application makes the examination easier: the patient can adjust on the screen what they see during the Polatest, while the app helps you calculate how many prism diopters may be required.

**Polatest images:**

* Cross
* Cross with fusion stimulus
* Horizontal/vertical clip
* Horizontal/vertical clock
* Double clock

---

**2.** The near Maddox-cross feature presents the well-known examination in a modernized form. Place a Maddox lens in front of one of the patient’s eyes, and the central dot will turn into a line, allowing you to detect deviations at reading distance.

---

**3.** When examining children, it can sometimes be difficult to keep their attention during the procedure. The app helps maintain their focus by showing random figures designed for children.

---

**4.** For patients suffering from central visual field loss (e.g., AMD), you can teach them to use the extrafoveal areas of the retina for reading. Using the red circle, you can guide their fixation while they attempt to read the text. You may support this with yoked prisms, and you can adjust the size and position of both the circle and the text to help them find the most effective gaze positions.

---

**5.** Once you have determined the necessary prism values, the built-in calculator helps you work out how to prescribe or order the glasses. You can use the commonly applied horizontal and vertical axes, but in special situations, you can also calculate with oblique prisms.

---

**Note:**
Under **Settings → Apps → polaHelp**, set the distance between the patient and the Polatest screen!
Since any application may contain errors, always double-check the prism diopter values. I cannot take responsibility for incorrectly manufactured glasses based on the app’s results.
The application is primarily designed for iPad.

polaHelp Pro – In-App Purchase
By purchasing polaHelp Pro, the application is expanded with the following additional tools:

PD / Exophthalmometer
Using the iPhone’s TrueDepth camera, the module performs a face scan to estimate interpupillary distance. After saving the measurement, manual fine adjustment is available.
Exophthalmus values are estimated based on the principles of the Hertel method. The results do not replace measurements obtained with a clinically validated Hertel exophthalmometer and are intended for informational and follow-up purposes only.
The measured values do not qualify as official medical data, and the application does not automatically store measurement data.

OKN Drum
A visual stimulus tool designed to elicit and observe optokinetic nystagmus, supporting the assessment of visual function in newborns and patients with limited cooperation (e.g. dementia).
During the examination, video recording can be performed to allow later review of the optokinetic response.

Camera Module
Utilizes the iPhone camera for anterior segment examinations, as well as for fundus assessment using 20–30 diopter lenses with a dilated pupil.
Both photo and video recording are supported.
