Ophthalmology for the Internist Robert F. Nash D.O. November 2006
2
Ophthalmology for the Internist Physical Exam Red Eye Acute Loss of Vision Complications of Systemic Diseases
3
Physical Exam Visual Acuity Confrontation visual field External Inspection Conjunctiva and sclera inspection Extraocular Muscles Pupillary Reactions Cornea and iris inspection Anterior chamber exam Lens clarity Ophthalmoscopic Exam
4
Red Eye Ophthalmology for the Internist Part I
5
Red Eye Conjuctivitis Corneal Injury Subconjunctival Hemorrhage IritisEpiscleritisScleritisTrauma Acute angle-closure glaucoma
6
Conjunctivitis Chemical conjunctivitis- Emergency –FLUSH-FLUSH-and FLUSH –Then, do your H&P –Acid v. Base Viral v. Bacterial conjunctivitis –Difficult to distinguish Purulent discharge- more common with bacterial etiology Pre-auricular lymphadenapathy- more common with viral etiology Sexually active
7
Conjunctivitis Allergic –Treatments Blepheritis –Seborrhea –Bacterial
8
Corneal Injury Sharp pain, improves with Topical anesthetic, worse with blinking Foreign body sensation Foreign Body v Keratitis Fluorescein to locate pathology
9
Keratitis Inflamed cornea –Contact misuse –UV damage –Dry eyes –Viral causes Treatment
10
Subconjunctival Hemorrhage Solitary red spot usually unilateral and always painless Causes: –Cough –Anticoagulation –Hypertension –Vomiting
11
Iritis Inflammation or iris and/or cilary bodies Predisposing Factors: –HLA B27 –Ankylosing spondylitis, –Reactive arteritis (Reiters syndrome), –psoriatic arteritis, –irritable Bowel disease –Crohn's disease –Multiple Sclerosis (HLA B15), –Sarcoidosis, –systemic Lupus Erythematosus –Lyme disease –Juvenile Idiopathic arteritis –Sexually transmitted diseases –Cat Scratch disease –Toxoplasmosis, toxocardia –Presumed Ocular Histoplasmosis syndrome –Lyme disease –whipples disease –valley fever –Tuberculosis –Leptospirosis –Rocky Mountain Spotted fever.
12
Iritis HPI: Pain, blurry vision, Photophobia PE: Sluggish, smaller pupil, “Cilary Flush”, Vessels do not blanch or move with swab Inflammatory cells seen with slit lamp Treatment: Corticosteroids Consult : Ophthalmology
13
Episcleritis Inflammation of superficial layer of sclera HPI: Red eye, sudden onset, without any known cause, minimal discharge with some discomfort PE Treatment: NSAIDS
14
Scleritis Strong association with system diseases –Rheumatoid arteritis –Chronic infections –Connective tissue disease Pain Treatment: systemic steroids Consult: Ophthalmology
15
Acute angle closure Glaucoma 5% of all Glaucoma Precipitated by dilation of pupil HPI: Eye pain, blurry vision, Haloes, Nausea and vomiting, Headache PE –Shallow anterior chamber –Pupil fixed –Cornea haziness –Eye feels firm
16
Acute angle closure Glaucoma Treatment –Pilocarpine – Miotic –Laser surgery - Iridectomy Consult - Ophthalmology
18
Acute Vision Loss Ophthalmology for the Internist Part II
19
Acute Vision Loss GlaucomaIritis Corneal Ulcer HyphemaHypopion Vitreous Hemorrhage Retinal detachment Retinal vascular occlusion Optic Neuritis Optic Neuropathy PapilledemaCVA
20
All require Ophthalmologic Consult
21
See above… GlaucomaIritis
22
Corneal Ulcer Bacteria v. Fungal Severe eye pain Can be seen on cornea as a white spot Topical Broad spectrum antibiotics
23
Hyphema Blood in anterior chamber Easily seen: red air-fluid level Traumatic cause most common Usually self limited Eye pressure must be monitored
24
Hypopion Leukocytes in anterior chamber Penetrating trauma to eye Antibiotics Consult Ophthalmologist
25
Vitreous Hemorrhage Extravasation of blood into potentional spaces in and around the vitreous body Blood blocks red reflex
26
Vitreous Hemorrhage Causes: –Proliferative Diabetic retinopathy (31.5-54%) –Retinal tears (11.4-44%) –Trauma (12-18.8%) –Neovascularization (3.5-16%) –Posterior vitreous Detachment with retinal vascular tears (3.7-11.7%) –Proliferative sickle cell retinopathy –Macroaneurysm (0.6-4.3%) Subarachnoid Hemorrhage
27
Vitreous Hemorrhage May cause retinal damage, floaters, and glaucoma Treat the underlying cause May require surgical removal of blood
28
Retinal Detachment Lifetime risk: 1 in 300 Causes: –Sarcoid iritis –Severe hypertension –Neoplasm –Fibrosis Retinopathy (DM) Trauma –Posterior Vitreous detachment
29
Retinal Detachment HPI: painless, curtain sensation, flashes of light Treatment: –Laser surgery –Scleral buckling –Posterior vitrectomy –Pneumatic retinopexy Prognosis: Good, if macula is not involved
30
Retinal Arterial Occlusion Causes –Emboli –TIA –Vasculitis –Must check Carotid circulation SuddenPainless Curtain sensation Cherry red spot – Fovea against the white retina Hollenhorst Plaques –Glistening yellow flakes Permanent or temporary (Amaurosis Fugax)
31
Retinal Arterial Occlusion Treatment –Ballot eye 10 sec cycles –Paracentesis of anterior chamber
32
Optic Neuritis Inflamed nerve MS May have pain behind eye PE: –May have optic nerve pallor –Pupil light reflex abnormality –Tenderness with ROM MRI Treatment: IV Glucocorticoids Note: 30-50% will develop MS within 15 years of diagnosis
33
Optic Neuropathy Giant Cell arteritis –Jaw Claudication –Over 60 –Malaise –Headache –Fever –Scalp tenderness –Weight loss –Polymyalgia Rheumatica Trauma –Disruption of vascular supply to optic nerve –Nerve impingement
34
Giant Cell arteritis 8-15% of all Temporal arteritis patients develop acute loss of vision If suspected –Sed rate >50 –Steroids –Temporal artery biopsy
35
Traumatic Optic Neuropathy Poor prognosis May try steroids, surgery
36
CVA May cause acute vision loss due to optic nerve infarct or cerebral infarct May cause partial vision loss unilaterally or bilaterally
37
Ophthalmologic Complications of Systemic Disease Ophthalmology for the Internist Part III
38
Ophthalmologic Complications of Systemic Disease Hypertension: A-V nicking Diabetes Mellitus: Diabetic Retinopathy Syphilis: Marcus-Gunn pupil Intracranial Edema: Papillary Edema Hyperthyroidism: Exophthalmos Herpes Zoster: Vesicles CMV Infection: Cotton wool spots
