BROAD H TEST

The Broad H test is used in ophthalmology to assess eye movements.

What it’s for:

The Broad H test is used to assess eye movements in all cardinal positions of gaze.

How it’s done:

  1. The patient is asked to follow a target (like a pen or light) with their eyes.
  2. The target is moved in a broad H shape.
  3. The examiner observes the patient’s eye movements for any limitations or abnormalities as the patient looks up and down, left and right.

What it shows:

The test helps identify:

  1. Limitations in eye movement that can indicate problems with the extraocular muscles or nerves supplying them.
  2. Cranial nerve palsies like III, IV, or VI nerve palsies.
  3. Internuclear ophthalmoplegia (a disorder of eye movements).
  4. Nystagmus (involuntary eye movements) or other abnormal eye movements.

The Broad H test is useful for detecting issues like strabismus or cranial nerve problems. It’s an important part of a comprehensive eye exam.

HORIZONTAL COINCIDENCE TEST

The horizontal coincidence test, also known as the cover-uncover test or Hirschberg’s test, assesses binocular alignment and detects strabismus (misaligned eyes).

How it’s done:

  1. Patient fixates: The patient looks at a target, usually a light or object.
  2. Covering one eye: One eye is covered, and the movement of the uncovered eye is observed.
  3. Uncovering the eye: The covered eye is uncovered, and the movement of both eyes is observed.

Purpose:

The test helps detect:

  1. Strabismus: Misalignment of the eyes (esotropia, exotropia, hypertropia, etc.).
  2. Binocular vision problems: Issues with how the eyes work together.

The test provides valuable information about binocular alignment and helps diagnose and manage strabismus and other binocular vision problems.

WORTH 4 DOT TEST

The Worth 4-Dot test is a clinical test used in ophthalmology and orthoptics to assess binocular vision and detect suppression or anomalies in binocular vision.

Key Features:

  1. Four dots: The test involves four dots or lights, typically arranged in a square or diamond pattern.
  2. Color filters: The patient wears red-green glasses or filters, with one eye seeing two dots (or lights) and the other eye seeing the other two.
  3. Binocular fusion: The test assesses the patient’s ability to fuse the images from both eyes.

Purpose:

The Worth 4-Dot test is used to:

  1. Assess binocular vision: Evaluate the patient’s ability to combine images from both eyes.
  2. Detect suppression: Identify suppression or anomalies in binocular vision, which can indicate conditions like strabismus or amblyopia.
  3. Monitor treatment: Track changes in binocular vision during treatment or therapy.

How it works:

  1. Patient views the dots: The patient looks at the four dots or lights through the red-green glasses.
  2. Response evaluation: The practitioner evaluates the patient’s response, noting whether they see four dots (indicating binocular fusion), two dots (indicating suppression), or some other pattern.

The Worth 4-Dot test provides valuable information about binocular vision and can help diagnose and manage various vision disorders.

SIMPLE EYE EXERCISES FOR STRONGER EYE MUSCLES.

Just like various parts of the body, the eyes are packed with muscles that help them perform better.

Over time these muscles can becoming weak. Thereby leading to several binocularity and refractive anomalies.

To ensure that these muscles are always power packed and ready for actions, the following exercises are necessary:

  1. Pushup: here you hold a pen at arms length while your two eyes are focused on the tip of the pen, you push the pen slowly towards your nose while ensuring that the tip of the pen does not break into two. When you cannot sustain that single image, you push the pen back again till the double image fuses into one. Do it back and forth again and again.
  2. Motility exercise: here you move your eyes in different direction of gaze repeatedly, up/down/left/right.
  3. For the third exercise, hold a pen close to your nose. Look at tip of the pen, then look at an object far away and then look back at the tip of the pen again. Do this repeatedly.
