Common Eye Problems In General Practice Steven B. Siepser, MD, FACS Attending Surgeon: Wills Eye C. A. Gunderson, M.D. Macro Approach ocular diagnosis Slit lamp for ophthalmologist History for Family Physician Gross appearance and clues Diagnosis confirmation Risk Management Anatomy Demonstration External Chemosis Lacrimal system and eye musculature American Academy of Ophthalmology Common Eye Disorders: Front to back anatomical Approach Ocular Movement Lids Orbit Lacrimal System Conjunctiva Cornea Globe Diagnostic steps to evaluate any eye patient # 1 Visual Acuity Short history and observation Eye versions Pupils tested Conjunctival discharge? Inspect cornea for opacities or irregularities Stain cornea with fluorescein Straight Eyes? Strabismus Thyroid Disease Exophthalmous Isolated lateral rectus paralysis Diabetes Isolated 3rd Intracranial 6th Nerve palsy Cardinal Signs Third Nerve Palsy Third Nerve Diabetes Advanced testing Glucose tolerance Hypertension Uncontrolled Neuro-consultation Diagnostic Tools Diagnostic steps Anterior chamber Depth Side Light Irregularities in pupil Look for proptosis Lid position Eye movement Anterior Chamber Depth Estimation American Academy of Ophthalmology Dilation “Lite” Mydriacyl .5% Pupillary check Make sure they return to normal in 8 hours. Checking Vision Available methods: Snellen letters Finger counting Simple approach flinch Proptosis Forward displacement of the globe Orbital or cavernous sinus disease Children, orbital infection or tumor Increasing severity Conjunctival hyperemia Limitation of ocular movement Proptotic eye Larger than the normal eye White sclera showing Lid Disorders Hordeolum/Chalazion Blepharitis Chalazion Starts as diffuse, tender, swelling localization of a nodule to the lid Hordeolum staphylococcal infection Glands of Zeis Lid margin Chalazion meibomian gland obstruction Chalazion Animation Hordeolum/Chalazion Treatment Treatment Warm compresses 5 minutes,4 times/day Zymar or Vigamox Zylet (steroid-antibiotic) Bacitracin ointment at night Prophylaxis Hordeolum/Chalazion Treatment Contd Lesions present for more than a month Refer to an ophthalmologist Incision and drainage is often needed Systemic antibiotics Hordeolum or chalazion with extension Periorbital Cellulitis Masquerading Lesions Chalazion. Blepharitis Chronic lid margin inflammation Types: staphylococcal or seborrheic Symptoms Foreign-body sensation Burning, debris Predispose Chalazia, blepharoconjunctivitis Lash loss Blepharitis Crusting in the lashes Thickened lid margin Blepharitis Treatment Warm compresses Lid scrubs Johnson and Johnson’s baby shampoo Thera-scrubs Bacitracin ointment Bedtime Restasis Doxycycline Preseptal Cellulitis - Symptoms Severe lid edema Eyelid erythema Normal ocular motility Normal pupil exam Fever Preauricular and submandibular adenopathy Orbital Cellulitis Posterior to the orbital septum Affects orbital contents Medical emergency Emergent consultations Infectious Disease Ophthalmologist Otolaryngologist Orbital Cellulitis Causes Ethmoid Sinusitis Paranasal Sinusitis Dacryocysitis Untreated Younger patients Orbital Cellulitis: Lid swelling Erythema Nasolacrimal Duct (NLD) Obstruction: Congenital and acquired 90% resolve without treatment Intermittent Infections Tears overflow Treatment Lacrimal sac Probe and irrigation Pattern of Redness Ciliary flush – iritis acute glaucoma American Academy of Ophthalmology Conjunctival hyperemia: American Academy of Ophthalmology Corneal epithelial disruption Observe reflection from the cornea Disruptions cause distortion and irregularity Fluorescein Breaks in the epithelium Stain bright yellow Cobalt blue light • Bright Green Symptoms can help determine the diagnosis Symptom Cause Itching , sandy feeling Allergy Scratchiness/ burning Trichiasis, dry eye Sharp ocular pain Foreign body, Abrasion Localized tenderness Dacryocystitis , Chalazion Symptoms Symptom Cause Deep, intense pain Episcleritis, Iritis, acute glaucoma, sinusitis Photophobia Corneal abrasions, iritis, acute glaucoma Corneal edema, acute glaucoma, contact lens over wear Halo Vision Common Eye Findings in conjunctivitis Eyemaginations Pupillary abnormalities Pupil smaller Iritis Inflammatory adhesions Pupil fixed and mid-dilated Acute angle closure glaucoma Marcus Gunn Optic Nerve Damage Conjunctivitis Inflammation Erythema Several causes: Bacterial Viral Allergic Chemical Conjunctivitis Key History Recent contact with red eye Spread Crusting or discharge? Any changes in vision? Does it itch? Conjunctivitis - Discharge Discharge Purulent Cause Bacteria Clear Viral White, stringy mucous Allergies Bacterial Conjunctivitis Erythema Purulent discharge May be monocular Morning crusted shut Bacterial conjunctivitis Purulent discharge Conjunctival hyperemia American Academy of Ophthalmology Bacterial Conjunctivitis Treatment Broad spectrum topical antibiotics Polytrim, Ocuflox, Ciloxan Warm compresses, remove crusts School once on antibiotics Refer 4 day rule Any vision change Viral Conjunctivitis Adenovirus Systemic viral infections Painful Herpetic Discordant lack of pain Viral Conjunctivitis (non-herpetic) HIGHLY CONTAGIOUS One eye to the second eye Often recent contact “pink eye” Children must be kept out of school Wash your hands and everything touched Viral conjunctivitis - symptoms Often bilateral Often with diffuse, marked hyperemia Watery discharge Chemosis ( swelling of conjunctiva) Some itching and foreign body sensation Preauricular adenopathy URI, sore throat, fever common Viral conjunctivitis Diffuse redness Watery discharge Viral conjunctivitis - treatment Cold compresses Good hygiene – wash hands, do not share Topical treatment for symptom relief Patanol, Acular No role for topical antibiotics Refer Decrease in Vision No resolution Viral Conjunctivitis - Herpetic Profuse watery discharge Eyelid ulcers and vesicles Permanent scarring and visual loss Refer Herpetic diagnosis made Decreased vision History of recurrence Herpetic corneal lesion Dendritic pattern. American Academy of Ophthalmology Rose Bengal Stain Allergic Conjunctivitis Hay fever, asthma, eczema Bilateral, seasonal Mild conjunctival hyperemia Chemosis prominent Itching and sandy feeling Not contagious Conjunctivitis-Allergic Erythema No watery discharge Allergic conjunctivitis - treatment Cold compresses Topical antihistamines (Livostin) Topical non-steroidals (Acular) Topical mast cell stabilizers (Alomide) Not effective until after one week of use Restasis Pataday Subconjunctival hemorrhage Bleeding Potential space: conjunctiva and sclera Resolve without sequelae No treatment Trauma,coughing, sneezing, coumadin No need for referral Subconjunctival hemorrhage Dry Eyes Associated with: Aging Females Rheumatoid arthritis Systemic medications Topical medications Dry eyes - treatment Artificial tear drops Systane Refresh Restasis Refer Punctal plugs Punctal occlusion Cornea Corneal Abrasions Corneal Ulcers Herpetic Keratitis Chemical Burns Corneal Abrasions Trauma Contact lens wear Symptoms: Pain, photophobia, redness Tearing, blurred vision Usually monocular Corneal Abrasions - Diagnosis Fluorescien dye Cobalt – blue light Abrasion will appear green. Topical anesthetic Alcaine Proparacaine Corneal Abrasions - treatment Heal within 24 hours Topical antibiotic drop Acular (Ibuprofen for the eye) Patient followed daily Refer to ophthalmologist Bandage contact lens Debridement Failure to heal in 24 hours Patching technique Antibiotic drop into the eye Proparacaine Close both eyes Place two eye pads over the affected eye Tape firmly start on Cheek for tension The patch should be removed in 24 hours Pressure patch applied to left eye Picture taken from Basic Ophthalmology for Medical Students and Primary Care Residents published by the American Academy of Ophthalmology Corneal Ulcer A localized, penetrating, infection Bacterial Fungal or protozoan (ameoba) Corneal Ulcer: Signs/Symptoms Pain Photophobia, Fixed pupil Foreign body sensation Conjunctival hyperemia White opacity on the cornea Anterior chamber inflammation (iritis) Hypopyon (pus in the anterior chamber) Corneal Ulcer Finger trauma Contact lens wear Tree=Fungus Corneal Ulcer: white lesion on the central cornea hypopyon conjunctival hyperemia American Academy of Ophthalmology Herpetic Keratitis Herpes simplex virus Follow up Place Patient on Acyclovir Refer Dendritic lesion of herpetic keratitis Herpetic Keratitis Complications and prognosis Recurrent process Corneal scarring Leads to visual loss Acid Injuries Acid burns Damage limited to area of contamination Sulfuric and Nitric acids most common Industrial Automobile battery explosions Alkaline Injuries Penetrate rapidly Produce intense ocular reactions Damage widespread, progressive Corneal opacification Scarring, severe dry eye Glaucoma and blindness Chemical Injury: Treatment Proparicaine Complete and copious irrigation of the eye Eye irrigation solutions or saline IV drip Irrigate under the lids Chemical Injury: Treatment Check the pH Place litmus paper Resume irrigation until pH neutralized Recheck pH in 30 minutes pH can rise after irrigation stopped Iritis – signs/symptoms Ciliary flush Photophobia (light sensitivity) Miotic pupil Keratic precipitates Hyphema Blood in the anterior chamber Usually associated with trauma Requires emergent referral Hyphema – Layer of blood American Academy of Ophthalmology Laceration Document Vision No direct Pressure Pupil points to opening Can be disguised with blood and mucous Place shield NPO, refer Laceration Thank You.
