  • The pupil may be fixed and mid-dilated in acute angle closure glaucoma

Blepharitis

  • Inflammation of the eyelid and eyelid margin
  • Usually bilateral and symmetrical
  • Subdivided into anterior and posterior blepharitis

Anterior Blepharitis

Blepharitis Complications

  • Tear film instability: Imbalance between aqueous and lipid components of the tear film, leading to increased evaporation.
  • Cutaneous: Acne rosacea (MGD) and Seborrhoeic dermatitis (seborrhoeic blepharitis) >90%
  • Lid: External hordeolum (stye) or internal hordeolum (painful, tender, red nodular masses near the eyelid margin), Chalazion formation
  • Cornea: Bacterial or marginal keratitis, recurrent epithelial erosion
  • Conjunctivae: Phlyctenulosis (rounded, elevated, gray or yellow, hyperemic, focal inflammatory nodules accompanied by a zone of engorged hyperemic vessels)
  • Contact lens intolerance
  • Inhibition of lid movement

Blepharitis Treatment

  • Lid hygiene: Gentle cleansing of the eyelid margins

Subconjunctival Haemorrhage

  • Blood beneath the conjunctiva causing a bright maroon red appearance.
  • May be idiopathic or caused by:
    • Hypertension
    • Valsalva maneuver (coughing, constipation, heavy lifting)
    • Bleeding diathesis
    • Anticoagulants
    • Trauma
  • Haemorrhage without a posterior margin may be associated with an intracranial bleed.
  • Check BP and IOP.
  • If recurrent, request coagulation screen and FBC.
  • Treatment is usually not required as the haemorrhage will fade over 2 weeks.
  • Refer to a haematologist if a bleeding diathesis is detected or a general practitioner if hypertensive.

Episcleritis

  • Inflammation of the episclera, the thin layer of tissue between the sclera and conjunctiva.
  • Redness that can be sectoral, diffuse, or nodular
  • Interpalpebral distribution
  • Usually peaks within 12 hours and then gradually fades over a few days

Episcleritis Treatment

  • Cool artificial tears may be sufficient in some cases
  • A weak topical steroid q.i.d. for 1–2 weeks is usually sufficient

Differentiation from Episcleritis

  • Instillation of 2.5% phenylephrine drops will constrict the conjunctival and superficial episcleral vasculature (episcleritis) but not the deep plexus (scleritis).

Keratitis/Ulcer

  • Inflammation or ulceration of the cornea.
  • Can be caused by:
    • Infection (bacterial, viral, fungal, protozoal)
    • Mechanical or trauma (foreign body)
    • Chemical (alkali injuries are worse than acid)

Classification of Scleritis

  • Diffuse scleritis: Generalized oedema with vascular congestion and dilatation.
  • Nodular scleritis: Single or multiple nodules, usually developing in the interpalpebral region. These have a deeper blue-red colour than episcleral nodules and are immobile.
