  1. How to Handle Common Eye Problemsin Your Practice Shuan Dai, FRANZCO Eye Doctors Ascot Hospital shuandai@eyedoctors.co.nz

  2. The Red Eye • A “Red Eye” may be due to an abnormality of the ocular structures including: • Adnexa • Lid Disorders • Lacrimal System • Orbital Disease • Globe • Conjunctival / Scleral Disorders • Corneal Disease • Uveitis • Glaucoma

  3. Adnexal Redness • Lids • Blepharitis • Stye • Chalazion • Topical Allergic • Lacrimal System • Dacryocystitis • Canaliculitis • Dacryoadenitis • Orbit • Cellulitis • Preseptal • Orbital

  4. Blepharitis • Symptoms & signs • Crusting • Oil droplets • Grittiness • Treatment • Lid hygiene • Doxycycline 100mg daily 4-6 weeks

  5. Stye& Chalazion

  6. Dacryocystitis • Recurrent watering eye • Mucous/purulent discharge • Abscess /lump over lacrimal sac • Blocked tear duct

  7. Ophthalmia Neonatorum • Infantile purulent conjunctivitis • Chemical from antibiotic drops/silver nitrate • Chlamydia • Gonorrhea • An ocular emergency as GC can invade the intact cornea and perforate the globe

  8. Lacrimal sac mucocele • An uncommon variant • Look for an elevated mass extending medially • Life threatening if infected – refer for intravenous antibiotics

  9. Dacryoadenitis • Acute painful • Swelling lateral upper lid • Viral/bacteria infection • Oral/iv antibiotics

  10. OrbitalCellulitis • Proptosis • Limited eye movement • Reduced vision

  11. Redness Confined to the Globe • Conjunctiva / Sclera • Subconjunctival hemorrhage • Ocular injection – conjunctivitis • Pingueculum / Pterygium • Episcleritis • Scleritis • Cornea • Keratitis • Corneal abrasion • Corneal ulcer • Anterior chamber • Iritis • Endophthalmitis

  12. Conjunctivitis • Bacterial • Purulent discharge • Papillary reaction • Associated blepharitis • Viral • Mucoid discharge • Follicular reaction • Associated URTI, epidemic • Allergic • Seasonal • Papillary reaction • Associated rhinitis, itching

  13. Bacterial Conjunctivitis • Symptoms: discharge, irritation • Signs: papillary conjunctivitis, perilimbal injection if associated keratitis • Treatment: chloramphenicol/fucithalmic • Danger: if hyperpurulent (gonococcal) or recent intraocular surgery REFER!

  14. Viral Conjunctivitis • Highly contagious, epidemics • Symptoms: previous URTI, previous contacts, mucoid discharge, often photophobia • Signs: preauricular node, pseudoptosis, follicular conjunctivitis ,conjunctival injection, punctate keratitis • Treatment: cool compresses, ocular lubricants. Referal • Warning: extreme infectivity, second eye at one week, lasts 10 – 14 days

  15. Allergy -Papillary conjunctival reaction

  16. Allergic Conjunctivitis • Symptoms: itching, seasonal, atopic history, rhinitis • Signs: papillary reaction, mucus • Treatment: cool compresses, ocular lubricants, anti-histamines - topical (Vasocon A) or systemic, Opticrom (Na chromoglycate) prophylaxis • Possible history of contact lens wear with giant papillary conjunctivitis • Treatment: • Lomide • Patanol • Steroid, i.e. FML

  17. Pingueculum & Pterygium Pingueculum is degenerative collagen within the interpalbebral fissure Pterygium extends onto the cornea

  18. Episcleritis & Scleritis Diffuse Scleritis Extremely painful Elderly, RA, systemic vasculitis Episcleritis Less painful Younger age No systemic association

  19. Herpes Simplex Keratitis • Viral replication in cornea • Symptoms: irritation, photophobia • Signs: • red eye involving limbus, • dendrite with terminal bulbs • seen best with staining • ulcer formation • Treatment: refer, antivirals, BEWARE STEROIDS!

  20. Herpes Zoster • Herpes Zoster Ophthalmicus • Suspect ocular involvement if the tip of the nose is involved (Hutchinson’s sign) • Oral acyclovir & topical acyclovir

  21. Iritis • Etiology • 50% idiopathic, unknown • Ocular disease • Large abrasion • HSV, HZV • Primary disease in young patients • Systemic disease • JRA – pauciarticular disease • Ankylosing spondylitis • Symptoms • Extreme photophobia • Reduced vision • Signs • Miosis • Red eye to limbus • Flare with cell • Treatment • Cycloplegia • Topical steroidsREFER

  22. Acute iritis • Light sensitivity • Deep dull ache • Smaller/ irregular pupil • Often idiopathic

  23. Angle Closure Glaucoma

  24. Subconjunctival Hemorrhage • Can occur secondary to blunt trauma or can be spontaneous • Lubrication if foreign body sensation • Warm compression

  25. Corneal Abrasion • Management • Non-contact lens wearer • Antibiotic ointment and patch • Follow-up one day • Contact lens wearer • DO NOT PATCH • Antibiotic ointment or drops • Follow up daily until healed • Treat abrasions created with organic material in this manner

  26. Corneal Ulcer • Risk of corneal ulcer when epithelium compromised, especially in contact lens wearers • Contact lens wearers have a higher rate of colonization with Pseudomonas

  27. Abrasion versus Ulcer

  28. Superficial Corneal Foreign Body • Removed under topical anesthetic • With burr or 25 gauge needle • Manage same as corneal erosion • Encourage safety glasses • Polycarbonate lenses

  29. Anterior Segment • Linear epithelial defects is suggestive of a foreign body under the eye lid

  30. Ultraviolet Radiation(arc eye) • Sources • Sunlamps, welding arcs • Management • Cycloplegics, antibiotic ointment, patch • Avoid long term topical anaethetic drop !!!

  31. Chemical Injury • Acid precipitates quickly • Alkali continues to penetrate • Therefore can progress over an extended period of time • Management • Continuous irrigation with saline until neutral pH • Test fornices with Litmus paper • Sweep fornices to remove retain debris • Antibiotic ointment, cycloplegics

  32. Chemical Injury Thorough irrigation before referral !!!

  33. Blunt Trauma • Hyphema • Indicates damage to angle and/or to the iris • Management • Vertical position • No anti-coagulants • Cycloplegics

  34. Blunt Trauma • Damage to Iris and Lens • Iridodialysis, cataract • Dislocation

  35. Blunt Trauma - Sequelae • Angle damage which can lead to glaucoma: can develop days to years after injury

  36. Blunt Trauma - Sequelae • A retinal tear which can progress to a retinal detachment

  37. Open Globe Injuries • Blunt trauma – rupture • Sharp trauma – laceration • Projectile trauma • Penetrating – in and out • Perforating ± intra ocular foreign body – just in

  38. Blunt Trauma • Severe trauma that resulted in a scleral rupture with delivery of the lens

  39. Sharp Trauma • Corneal laceration and traumatic cataract from a thrown beer bottle

  40. Penetrating Eye Injuries • Intraocular foreign bodies generally have to be removed, unlike orbital (extraocular) foreign bodies

  41. Perforating Trauma • Patient was hammering and noticed a spark fly up to his eye.
