Patterns of Dry Eye: The Chart Tells the Story Before the Exam Ever Starts

By Cheryl Chapman, OD, Dry Eye Specialist

One of the most underrated tools in dry eye care isn’t the slit lamp or the meibography—it’s the intake form. Before I ever examine a patient, I can usually tell who deserves a closer look simply by reviewing their symptom survey, particularly the OSDI-6 or similar dry eye questionnaires.

Dry eye rarely announces itself with one dramatic complaint. Instead, it shows up as a pattern—and certain responses immediately raise my index of suspicion.

Fluctuating Vision Is a Big Red Flag

When a patient reports blurry or fluctuating vision that improves with blinking, I slow down. Vision that comes and goes throughout the day, especially worsening with screen time or driving, often points to tear film instability rather than a refractive problem.

These are the patients who say: “My vision is fine in the morning but terrible by afternoon.” or  “I blink and it clears… for a second.”

Burning, Stinging, or Grittiness = Inflammation Until Proven Otherwise

Any mention of burning, stinging, or a sandy, gritty sensation immediately moves dry eye higher on my differential. These symptoms often correlate with ocular surface inflammation, lid margin disease, or evaporative dry eye, even if the patient doesn’t label it as “dryness.”

Many patients normalize these sensations because they’ve lived with them for years. The intake interview helps surface what they’ve stopped questioning.

Contact Lens Intolerance Is a Clue

If a patient notes discomfort with contact lenses, reduced wearing time, or needing to remove lenses earlier than expected, I pay attention. Contact lens intolerance often exposes dry eye.

Patients who “used to love their contacts” but now avoid them are often telling us that the ocular surface has changed.

Excessive Tearing Can Still Mean Dry Eye

Paradoxically, watery eyes make me think about dry eye more - not less. Reflex tearing is a common response to surface irritation and meibomian gland dysfunction.

When a patient checks boxes for both tearing and dryness, that combination is particularly telling.

Environmental Triggers Seal the Deal

Symptoms that worsen with:

• Screen use
  

• Wind or air conditioning
  

• Driving
  

• Reading
  

…are classic for evaporative dry eye. These responses tell me the tear film isn’t holding up under stress, which often means lipid layer deficiency or poor blink mechanics.

Why This Matters

Dry eye doesn’t live in isolation. It affects vision quality, comfort, contact lens success, and long-term ocular health. And often, the first warning signs are already written down before the patient ever sits in the exam chair.
