fit with disposable contact lenses to address the anisome-tropia, but he was unable to tolerate insertion and removal.By manipulating the shape and power factor of the spectaclemagnification equation, a new spectacle lens was designedO.D. to increase magnification and reduce aniseikonia.Using a high-index, aspheric lens with a 3.0 mm safetythickness in the more myopic eye, the vertex distance wassignificantly reduced and the lens thickness increased, re-sulting in a favorable increase in magnification. With theaddition of 2PD base down O.D., the patient maintainedsingle, comfortable binocular vision with his full manifestrefraction.Conclusion: By manipulating the spectacle magnificationequation, the practitioner can utilize spectacle lenses toreduce aniseikonia secondary to anisometropia in postsur-gical patients. Prism can then be added to solve issues withocular misalignment.

Successful Prism Treatment in Two Cases of IsolatedOculomotor Nerve PalsyDiane Galbrecht, O.D., Linda Marks, O.D., andAaron Franzel, O.D., University of Missouri-St. LouisCollege of Optometry, One University Boulevard, St.Louis, Missouri 63121-4400
Background: An oculomotor (third cranial nerve) palsyresults from damage to the oculomotor nerve anywherealong its course in the brain. Both congenital and acquiredforms can be total or partial, causing variances of pupil,eyelid, and extraocular muscle abnormalities. Ocular motil-ity is drastically affected by oculomotor nerve palsies withlimitation of elevation, depression, and adduction.Case Reports: We compared diagnosis and treatment of 2adult females with long-standing oculomotor nerve palsies;1 acquired and 1 congenital. The acquired-onset patient hadbeen in a motor vehicle accident 41 years prior. She wassuffering from diplopia that was reduced by tilting her head.The head tilt led to torticollis and eventually caused grad-ually worsening neck pain. The patient with congenitaloculomotor palsy did not experience diplopia but had ratherunusual episodes of visual disturbance accompanying eyepain and headaches. She had cyclical spasms, whereby themagnitudes of her ptosis and eye turn were variablethroughout the day. Gradual worsening of her symptomshad prompted her to seek treatment.Conclusion: Although these patients exhibited vastly differ-ent symptoms, both experienced relief by incorporatingyoked prism into their spectacles. Moderate amounts ofyoked prism were used to eliminate diplopia and lessen thehead tilt in the case of the acquired third nerve palsy. Smallamounts of yoked prism and limited vision therapy re-established an appropriate visual-spatial projection in thecase of the congenital third nerve palsy. The patient expe-rienced considerable relief from her visual disturbances andocular pain.

Shedding Light on the Herpes Simplex Virus: ShouldUV Transmission Characteristics be Considered WhenPrescribing Contact Lenses for Patients With HerpeticEye Disease?Elizabeth Sanders, O.D., Arnie Patrick, O.D., andAndrea Janoff, O.D., Nova Southeastern University,College of Optometry, 3200 South University Drive, Ft.Lauderdale, Florida 33328
Background: Herpes simplex virus (HSV) is a leading causeof infectious visual loss in developed countries. Systemicinfection is nearly universal, although usually asymptomaticand self-limited. After initial infection, the virus spreads toregional ganglia where it remains latent until reactivation.Recurrent herpetic ocular disease has several known andsuspected reactivation factors. These include fever, UVlight exposure, menstruation, stress, and trauma.Case Report: A 16-year-old black male presented with C/Oof an intermittent red eye O.D. that started 2 months earlierafter being refit with CLs. He had successfully worn Acuvue2 for 5 years, but was refit with O2 Optix for improvedocular health. SLE O.D. revealed 2� conjunctival folliclesand injection, a dendritic corneal ulcer, and 1� cells andflare in the AC. The patient was diagnosed with HSVkeratoconjunctivitis with a secondary uveitis. After success-ful treatment with Viroptic, he was refit with Acuvue Oasys.Conclusion: Relatively little is known about the factors thatcause recurrent ocular HSV infection. Although the Her-petic Eye Disease Study Group attempted to quantify them,it left questions unanswered, including the complete role ofUV light exposure. Our patient experienced his first ocularHSV outbreak shortly after being refit from UV-protectivecontact lenses to lenses without UV protection. While it cannever be known if this change triggered the outbreak, thetiming suggests that it could have. Although clinicians havelong recommended spectacle UV protection to their pa-tients, we believe that it would also be prudent to suggestUV attenuating contact lenses to ocular HSV patients.Anterior segment photographs, information about herpeticeye disease, and differential diagnoses will be included.
