Case Report: A 48-year-old woman came in for a glaucoma work-up evaluation secondary to large, symmetric C/D ratios and a positive family history of glaucoma. The patient reported no ocular or visual symptoms. Medical history was positive for systemic hypertension, well-controlled with oral medication, and seasonal allergies, also well-controlled with medication.

Indirect ophthalmoscopy revealed C/D ratio of 0.75 round with healthy rim tissue, and no retinal pathol- ogy noted O.D.; C/D ratio of 0.65 round with healthy rim tissue, and a focal area of retinal edema with circinate exudation adjacent to the nasal optic disk margin O.S. No additional retinal pathology was noted O.S. Conclusion: A diagnosis of idiopathic juxtapapillary cho- roidal neovascular membrane O.S. was confirmed with fluorescein angiography and OCT.

Poster 82 Visudyne Photodynamic Therapy in Ocular Histoplasmosis John Sharpe, O.D., Southern College of Optometry, 1245 Madsion Avenue, Memphis, Tennessee 38104 Background: Presumed ocular histoplasmosis syndrome (POHS) is a well-documented eye disease, believed to be caused by the fungus Histoplasma capsulatum. It manifests clinically with a disseminated choroidopathy (histo spots), peripapillary choroiditis (peripapillary atrophy), and sub- retinal neovascular maculopathy (CNV). Until recently, treatment options were limited to laser photocoagulation, surgical CNV excision, and perhaps high-dose corticoste- roid therapy. With the FDA approval of Visudyne, photo- dynamic therapy (PDT) has now become a popular alterna- tive to treating subfoveal choroidal neovascular membranes associated with POHS. This case chronicles POHS with active maculopathy and the retinal healing process follow- ing multiple PDT applications over a 2-year period. Case Report: A 34-year-old woman came in for an evalu- ation of blurry, distorted vision in the right eye. The patient reported a “hard to describe” distortion of vision O.D., slowly worsening over the previous 3 to 4 months. Medical history was unremarkable. Best visual acuity measured 20/20 – O.D. and 20/20 O.S. Biomicroscopy was unremark- able O.D. and O.S. Intraocular pressure by applanation tonometry measured 18 mmHg O.D. and O.S. Indirect ophthalmoscopy revealed: C/D ratio of 0.50 round with peripapillary atrophy; multiple mid-peripheral, white, punched-out, retinal lesions; and a focal, pigmented retinal elevation with edema and hemorrhage 2 mm inferior tem- poral to the fovea O.D.; C/D ratio of 0.55 round with peripapillary atrophy and multiple mid-peripheral, white, punched-out, retinal lesions O.S. Conclusions: A diagnosis of presumed ocular histoplasmo- sis syndrome OU and juxtafoveal choroidal neovascular membrane O.D. was made.

Vitreomacular Traction Syndrome: The Usefulness ofOCT in Management and TreatmentSusannah Marcus-Freeman, O.D., andJoseph Convertino, O.D., Malcom Randall VA MedicalCenter, 2038 SW 102nd Terrace, Gainesville, Florida32607

Background: Patients with vitreomacular traction (VMT)syndrome may report metamorphopsia, reduced visual acu-ity (VA), or photopsias. VA may range from mildly reducedto the 20/400 level. On examination, partial PVD is presentwith persistent macular attachment. Macular signs may besubtle, and include CME and/or thickened epiretinal tissue.OCT reveals a tented foveal appearance, making the diag-nosis of VMT obvious.Case Report: A 61-year-old man came in with a chiefsymptom of floating spots and “sparkly things” in his righteye central vision for the previous month. His ocular historywas remarkable for blunt trauma to the left eye 1 yearearlier. His medical history included hypertension and aor-tic bifemoral bypass. His best-corrected VA was 20/150O.D. and 20/20 O.S. Slit lamp examination, pupils, andintraocular pressures were all unremarkable. Dilated fundusexamination revealed an incomplete posterior vitreous sep-aration and a subtle area of thickened hyaloid overlying themacula O.D. Optical Coherence Tomography (OCT) re-vealed a tuft of vitreoretinal tissue causing traction anddramatically disrupting the foveal architecture in a tent-likefashion. The diagnosis of VMT syndrome was made. Sur-gical intervention was recommended by the retinal special-ist, and pars plana vitrectomy with membrane peel wassubsequently performed. Postoperative OCT revealed a sig-nificant decrease in the macular thickness and release of thetraction on the fovea.Conclusion: Historically, it has been sometimes difficult todifferentiate between early macular hole, epiretinal mem-brane, and VMT syndrome. Because the prognosis, man-agement, and treatment differ among them, it is very im-portant the correct diagnosis be made. With the use of newimaging technologies—particularly OCT—such diagnosishas been considerably simplified, as each entity can beeasily distinguished from the others.

Azoor: Proper Testing and DiagnosisSimi Bhardwaj, O.D., PCO/Seidenberg Protzko EyeAssociates, 103 Remington Circle, Havre De Grace,Maryland 21078

Background: White dot syndromes are often acute condi-tions that occur with or without visual loss. Acute zonal

occult outer retinopathy (AZOOR) is a white dot syndrome,presumed to be an inflammatory disorder, damaging broadzones of the outer retina in one or both eyes. AZOOR isusually seen in young women with an acute onset ofphotopsia. Diagnosis of AZOOR is often missed withoutaccurate diagnostic tests. An accurate diagnosis is made bycombining results from the fundus evaluation, visual-fieldtesting, fluorescein angiograms, and an electoretinogram(ERG).Case Report: A 16-year-old girl was brought to the officereporting flashing lights for 3 days. The patient’s medicalhistory is unremarkable presently, but she stated she had acold the week before. Anterior and posterior segment eval-uation of left eye was found unremarkable; however, pos-terior segment of the right eye showed white dot-like lesionsin the nasal periphery. Trace vitreous cells were seen pos-teriorly in the right eye. No retinal detachment was noted ineither eye. Fundus photographs were taken and a diagnosisof white dot syndrome was made. The patient was referredto a retinal specialist for further evaluation, where a floures-cein angiogram, visual fields, and an ERG were called for.Based on the characteristic findings, the patient was diag-nosed as having AZOOR.Conclusion: AZOOR is a condition in which inflammationcauses the eye to malfunction. Seeing flashing lights andhaving an enlarged blind spot are symptoms of AZOOR.The area of visual loss may increase for a period of time andthen stabilize. In the majority of patients, the retina recoversits function and sight returns over 1 to 3 years. Flouresceinangiography shows retinal and optic nerve head capillaryleakage. Visual-field testing may show a scotoma, whereasan ERG would be markedly reduced. Although an ERG isnot commonly performed, an understanding of the diseaseand proper testing become imperative toward diagnosis ofAZOOR.

Optic Nerve Head DrusenRobert Carter, O.D., and Sherah Eavey, O.D., MichiganCollege of Optometry at Ferris State University, 1310Cramer Circle, Big Rapids, Michigan 49307

Background: Optic nerve head drusen, thought to be theresult of abnormal axonal metabolism, are typically bilat-eral, present in 0.4% to 3.7% of the population, and slowlyprogressive. The most notable complication is progressiveperipheral vision loss.Case Report: A 15-year-old girl had lost her glasses andpresented with a symptom of blurred vision. Cycloplegicrefraction results were �2.50 DS O.D. and �4.75 DS O.S.,with visual acuities of 20/20 O.D. and 20/30� O.S. Oph-thalmoscopy revealed disc elevation and surface drusenOU. All other findings were normal.
