Differential Diagnosis for Ms. V. M.

Single Most Likely Diagnosis

  • Dry Eye Syndrome: The patient's symptoms of eye irritation, gritty sensation, burning, and increased light sensitivity, particularly in the afternoon, are classic for dry eye syndrome. The presence of punctate epithelial erosions, reduced tear break-up time, and abnormal Schirmer's test results further support this diagnosis. The patient's history of prolonged screen use and decreased tear production also contribute to this condition.

Other Likely Diagnoses

  • Blepharitis: The patient's symptoms of eye irritation and the presence of pouting Meibomian glands that secrete turbid material when the lids are massaged suggest blepharitis. This condition often coexists with dry eye syndrome and can exacerbate its symptoms.
  • Meibomian Gland Dysfunction: The patient's symptoms and the presence of turbid secretions from the Meibomian glands suggest Meibomian gland dysfunction, which is a common cause of dry eye syndrome.
  • Computer Vision Syndrome: The patient's prolonged screen use and symptoms of eye irritation, blurring of vision, and eye strain are consistent with computer vision syndrome.

Do Not Miss Diagnoses

  • Sjögren's Syndrome: Although less likely, Sjögren's syndrome is an autoimmune disorder that can cause dry eye syndrome and should be considered, especially given the patient's history of Graves' disease (an autoimmune disorder). Missing this diagnosis could lead to delayed treatment and potentially severe complications.
  • Thyroid-Associated Orbitopathy: The patient's history of Graves' disease increases the risk of thyroid-associated orbitopathy, which can cause eye irritation, redness, and vision changes. Although the patient's symptoms are not typical for this condition, it should be considered to avoid missing a potentially serious diagnosis.

Rare Diagnoses

  • Keratoconjunctivitis Sicca: This is a rare condition characterized by severe dry eye syndrome, often associated with autoimmune disorders. Although the patient's symptoms are consistent with dry eye syndrome, the severity and presence of other systemic symptoms would be necessary to consider this diagnosis.
  • Lacrimal Gland Dysfunction: This is a rare condition that can cause dry eye syndrome due to abnormal lacrimal gland function. Further testing would be necessary to consider this diagnosis.
