Maskin Probing for Meibomian Gland Obstruction

Advanced Treatment for Refractory Dry Eye

Bellevue, Washington

Chronic dry eye is frequently driven by meibomian gland dysfunction (MGD).

In some patients, gland obstruction becomes fibrotic and resistant to conventional therapies such as warm compresses, IPL, or gland expression.

For selected cases, Maskin Meibomian Gland Probing may be considered.

What Is Maskin Probing?

Meibomian gland probing (commonly referred to as Maskin probing) is a procedure designed to mechanically relieve intraductal obstruction within the meibomian glands.
Using specialized sterile micro-instruments, the gland ducts are carefully dilated to relieve fixed obstruction and restore flow.
The technique was developed and described in peer-reviewed literature by Dr. Steven Maskin.

Why Probing May Be Necessary

In advanced MGD, chronic inflammation may lead to:

• Ductal fibrosis

• Fixed obstruction

• Elevated intraductal pressure

• Gland atrophy over time

When obstruction becomes structural and fibrotic, heat-based therapies alone may not fully relieve blockage.

Probing directly addresses fixed ductal resistance.

Who May Be a Candidate

Maskin probing is not first-line therapy.

It may be considered in patients who demonstrate:

• Meibomian gland obstruction on imaging

• Persistent symptoms despite IPL or thermal therapy

• Gland tenderness or elevated intraductal pressure

• Dropout progression

• Chronic, refractory evaporative dry eye

Objective meibography imaging is used to guide decision-making.

How It Fits Within Our Treatment Model

Dry eye care in our clinic is structured across three domains:

1. Structural

2. Inflammatory

3. Neurosensory

Maskin probing addresses the structural component when fixed obstruction is present.

It may be combined with:

• Intense Pulsed Light (IPL)

• Radiofrequency therapy

• Anti-inflammatory strategies

• Nutritional optimization

• Blink and neurosensory evaluation

• Neurolens when binocular strain contributes

• ExoMind when stress regulation is relevant

Treatment sequencing is individualized.

What to Expect

The procedure is performed in-office using sterile technique.

Topical anesthetic is applied.

Micro-probes are inserted into the gland orifices to relieve obstruction.

Post-procedure care may include:

• Anti-inflammatory therapy

• Lubrication

• Ongoing gland support

Individual experiences vary.

A detailed consultation is required before determining candidacy.

Is There Evidence Supporting Probing?

Peer-reviewed publications have described improvements in:

• Gland obstruction

• Symptom relief

• Lid tenderness

However, probing remains a specialized procedure and is typically reserved for refractory cases.

It is not appropriate for all dry eye patients.

Important Considerations

Maskin probing:

• Does not regenerate lost glands

• Does not replace inflammatory management

• Is not necessary for early MGD

• Should be guided by imaging and clinical findings

Proper patient selection is essential.

Frequently Asked Questions

Is Maskin probing painful?
Topical anesthetic is used. Sensation varies by individual.

How long does improvement last?
Results vary depending on gland condition and ongoing inflammatory control.

Is this better than IPL?
They address different aspects of MGD. Probing addresses fixed obstruction; IPL targets inflammatory vascular changes.

Schedule a Structural Evaluation

If you have persistent evaporative dry eye despite standard therapy, a structural evaluation may determine whether probing is appropriate.
