17 Temporal Artery Biopsy Outcomes in Patients with Suspected Giant Cell Arteritis Lillian Yang, MD, Resident, Class of 2016 Primary Supervisor: Jason Sokol, MD Giant cell arteritis (GCA) is a systemic disease that can have devastating ophthalmic consequences. The diagnosis is based on clinical characteristics and established by the presence of inflammatory markers. However, the only specific diagnostic test is a temporal artery biopsy (TAB). Although uncommon, complications related to TAB, such as postoperative hematoma, scalp necrosis, wound infection, damage to facial nerve, and drooping of eyebrow, can occur. Additionally, TAB as a diagnostic tool for GCA is not perfectly sensitive, with reported rates of 70 90%. This presentation is intended to review results from temporal artery biopsies performed at the University of Kansas Hospital and to determine their utility in diagnosing GCA.
18 Bilateral Orbital Myeloid Sarcoma in an Adult Patient with Recurrent Acute Myeloid Leukemia (AML) Reid Mollman, MD, Resident Class of 2018 Primary Supervisor: Jason Sokol, MD Objective: Here, we discuss a single case of Myeloid Sarcoma, also previously referred to as chloroma or granulocytic sarcoma, which manifested as bilateral orbital masses in an adult with recurrent AML. Method: Presentation of a single case of bilateral orbital Myeloid Sarcoma in an adult with recurrent AML. Results: The patient in this case presented with substantial proptosis and ophthalmoplegia secondary to large bilateral Myeloid Sarcoma orbital masses in the setting of recurrent AML. Six weeks after treatment with intrathecal chemotherapy, as well as radiation, the patient had virtually complete resolution of the orbital masses. Conclusion: This is an interesting and rare case, where an adult patient presented with bilateral orbital Myeloid Sarcoma. It is very rare for myeloid sarcoma to present in the orbit, and, making this case even rarer, is the presentation in an adult. Upon literature review, it appears that only approximately 20 cases of this nature have been described in the past two decades.
19 Recurrent Squamous Cell Carcinoma with Orbital Invasion (some requiring exenteration) in the Setting of Immunosuppression Following Organ Transplants Case Series Joshua Jones, MD, Resident Class of 2018 Primary Supervisor: Jason Sokol, MD Purpose: Review current literature on anti graft medication pharmacology and discuss the increased risk of squamous cell carcinoma in transplant patients, along with retrospectively reviewing cases in which transplant patients were treated by an interdisciplinary team, including Oculoplastics and Otolaryngology for squamous cell carcinoma with orbital involvement. Design: Charts were analyzed from four patients who underwent surgical resection, some radical, for treatment of squamous cell carcinoma following immunosuppressive therapy for transplants between 2011 and 2016, recording the association with the type of immunosuppressive medication and blood levels, extent of invasion of the tumors and type of procedure required for effective treatment. Setting: Ophthalmology Department at a university hospital setting Patients: Among the 4 patients included, average age was 62 years old; 2 were male and 2 were female. One patient was deceased at the time of retrospective review, due to metastatic disease. Each patient had a different type of transplant, such as heart, liver, kidney or bone marrow. The average time at initial diagnosis of squamous cell carcinoma was 6.3 years following initiation of anti graft medication. Conclusions: Squamous cell carcinoma is a significant cause of morbidity and mortality for patients on long term immunosuppression following otherwise successful transplants. In our series of 4 patients, 50% required lifesaving radical surgical resection, including exenteration. Even with a successful surgery, the rate of mortality is high, given the extent of invasion. Our findings confirm what other studies have shown: that these patients need to be monitored closely for signs of peri orbital malignancy and treatment should not be delayed, given the high rates of recurrence and tissue invasion.
20 Retrospective Review of Indications of Evisceration, Enucleation or Exenteration at one Academic Institution Derek Horkey, MD, Resident Class of 2017 Primary Supervisor: Jason Sokol, MD Purpose: At times in ophthalmology, instead of vision enhancing or vision preserving procedures, it is necessary to perform eye destructive procedures, including evisceration, enucleation, and exenteration. The purpose of this study was to analyze, over a five year period, the number of eye destructive procedures and investigate the most common indication for said procedures. Methods: After obtaining IRB approval, all medical records from August of 2010 February of 2015 from patients having eye destructive procedures performed by one surgeon at one academic tertiary care facility were reviewed, investigating clinical indication for the procedure. Results: There were 103 eye destructive procedures performed on 101 patients at one institution over the roughly 5 year period. Of these 103, 69% of the procedures were enucleations, 27% were exenterations and 4% were eviscerations. The two most common indications for procedure were trauma (40%) and malignancy (34%). The other noted indications were blind painful eye (15%), infection (10%) and ruptured cornea (1%). Discussion: As one might imagine, more complicated cases were very common indications for eye destructive procedures at a tertiary care center. The hospital is a level I trauma center, which would account for a high volume of trauma cases. Also, given that there is a large cancer center, the high incidence of malignancy is accounted for as well. There were also five exenterations performed because of invasive mucormycosis. In these five patients, four had known malignancies and one had immunodeficiency, secondary to unknown reason, which was being worked up at the patient s time of death. These numbers suggest that often complicated orbital trauma and malignancies are transferred or referred to tertiary care centers for definitive management and treatment. Our institution has a large cancer center, which contributes to our significant number of procedures secondary to those malignancy, as well as malignancy related infections. References: 1.

55 Risk Factors for Intraocular Pressure Elevation After Dexamethasone Intravitreal Implant Julie Quick, MD, Resident Class of 2017 Primary Supervisor: Paul Munden, MD Purpose: Intravitreal steroids are a recognized cause of increased intraocular pressure (IOP). The goal of this study was to analyze what risk factors are associated with the dexamethasone intravitreal implant 0.7 mg (DEX implant) and what medical and surgical interventions were necessary to control the IOP. Methods: A retrospective, descriptive, chart review was performed after IRB approval. All patients who received a DEX implant by a single retinal surgeon in our department between 2014 and 2016 were identified. In each case, gender and age of the patients, diagnosis, number of reinterventions and laterality were registered. Results: Out of 48 patients (60 eyes) who received the DEX implant, 13 eyes (22%) had an IOP elevation > 5mmHg from baseline. On average, peak IOP was 6 weeks after injection. Eight eyes (62%) with IOP elevation were adequately controlled with an average of two IOP lowering drops; 4 eyes (30%) required filtering surgery and 1 eye (8%) did not require intervention, as the IOP was < 21mmHg. The most common diagnosis associated with elevated IOP was posterior uveitis (30%) followed by DME (27%), BRVO (18.8%) and CRVO (12.5%). Nine patients had a history of primary open angle glaucoma (POAG). Of these patients, 3 had an IOP elevation > 5mmHg. Two of these patients were not taking IOP lowering medications at the time of their injection. The 6 patients who did not have an IOP elevation were already on either an IOP lowering drop or had a history of glaucoma surgery. All 4 patients with a known history of increased IOP after topical steroids had an IOP elevation after DEX implant. Conclusions: The majority of patients who had an elevated IOP after DEX implant were controlled with IOP lowering medications. A history of glaucoma that is untreated, posterior uveitis, DME, and history of steroid response are potential risk factors for IOP elevation and should be monitored closely.
56 Pattern Dystrophy: Case Series Luke Dolezal, MD, Resident, Class of 2018 Primary Supervisor: Ajay Singh, MD Pattern dystrophies are a group of macular diseases characterized by various patterns of pigment deposition and lipofuscin accumulation within the macula due to RPE dysfunction. Patterns may fluctuate in individual patients over time and may differ between eyes. Disease onset is typically in the 5 th 6 th decade. They have a relatively good visual prognosis, although slow progressive central vision loss may occur, including severe vision loss in up to 50% of patients after age 70, due to chorioretinal atrophy and/or CNV. Patients diagnosed at an older age may be misdiagnosed as having age related macular degeneration, due to a similar fundus appearance. Accurate diagnosis is important to avoid unnecessary treatment and patient anxiety. This presentation will review cases of Pattern Dystrophy seen at KU Eye Clinic. We will discuss clinical features and multimodal imaging used in the diagnosis and monitoring of these patients.

61 Tear Osmolarity in Diabetic Patients Michelle Boyce, MD, Resident, Class of 2016 Primary Supervisor: Ajay Singh, MD Diabetes Mellitus is a prevalent condition in the United States with many associated ophthalmic complications, including diabetic retinopathy and ocular surface disease. Studies have shown ocular surface disease is more common in the diabetic population than the general population. 1,2 Diabetic patients have been shown to have a multitude of ocular surface irregularities that lead to the morbidity associated with ocular surface disease. Studies of diabetic patients have demonstrated changes in tear osmolarity, 3 tear film instability, 2,4 decreased reflex tearing, 5 decreased corneal sensation, 6,7 and loss of goblet cells. 4,5 Deceased corneal sensation and the resultant decrease in sensory input to the autonomic nerves of the lacrimal gland may lead to reduced basal and reflex tear secretion Additionally, studies have shown that panretinal photocoagulation (PRP) used in the treatment of proliferative diabetic retinopathy may alter the corneal subbasal nerve plexus 11,12 and corneal sensitivity. 6,13,14 Prior studies have shown variable results when assessing if diabetes disease severity markers can be correlated to the presence and severity of ocular surface disease. 3,15,16 Common clinical testing for diagnosis and management of ocular surface disease includes tear break-up time (TBUT), Schirmer testing for tear production, staining of the cornea and conjunctiva, and tear osmolarity. Tear osmolarity is regarded as a hallmark of dry eye and has been shown to be the single best marker for diagnosis and classification of dry eye. 17,18 Our study objectives were to determine if tear osmolarity in diabetic patients could be correlated to markers of diabetes severity, such as duration of disease, severity of diabetic retinopathy, history of requiring treatment by PRP, and history of nephropathy or neuropathy. Additionally, we examined the effects that PRP had on symptoms of ocular surface disease and tear osmolarity. Results of the research provides insight into the course of ocular surface disease in diabetics, particularly those patients with proliferative diabetic retinopathy requiring PRP, and allows us to better treat the morbidity associated with these conditions.

78 Effects of Simulated Afferent Pupillary Defect on Automated Perimetry Robert Null, MD, Resident, Class of 2017 Primary Supervisor: Paul Munden, MD Glaucoma is a progressive optic neuropathy characterized by known patterns of vision loss. Functional testing of visual fields through automated perimetry allows the clinician to monitor for glaucoma progression. Predictive threshold models, most notably the Swedish Interactive Thresholding Algorithm (SITA) have been developed to speed testing time, and judicious statistical analysis of field data can provide insights into rate of disease progression and efficacy of treatment. However, it is less well understood how these statistical models behave when other etiologies of vision loss are introduced. To further investigate the behavior of these models, otherwise healthy subjects participated in at 24-2 SITA fast automated visual field in the dominant eye. Fields were tested with and without the presence of 0.9 neutral density (ND) filter to simulate a non-specific, quantifiable, generalized visual depression. Statistical parameters commonly utilized to assess glaucoma severity and progression, including mean deviation, pattern deviation, and visual field index (VFI), were compared between filtered and non-filtered fields, with significant trends reported in detail in the accompanying presentation. Vision loss from glaucoma does not occur in a clinical vacuum and better understanding of commonly used statistical metrics under non-ideal conditions will aid the clinician in the assessment and management of this complex disease.

GPA cannot determine if deviation at that point statistically significant Usually in areas where defect already very deep or absolute GPA Alert Alerts to deterioration in consecutive tests Applies to the whole field, not individual points
84 Detecting Functional Change in Progressing Glaucoma: Visual Field Guided Progression Analysis (GPA), continued: No Progression Detected Possible Progression statistically significant deterioration in 3 or more points on two consecutive tests Likely Progression statistically significant deterioration in 3 or more points on three consecutive tests VFI Plot Graphs VFI values of included exams as a function of patient s age Clinical Interpretation Linear regression analysis of VFI over time At least 5 exams over 2 years Not drawn when slope positive (learning effect) Not drawn when 95% confidence level on slope is greater than 5% VFI Bar histogram indicates current VFI value and will graphically indicate the 2 to 5 year projection of the linear progression line. GPA Software is a statistical analysis software not a replacement for clinical observation and physician interpretation Aid in analysis of data - does not make clinical judgment How does it compare to the experts when calling progression? Level of agreement between majority expert consensus of subjective determination of visual field progression and GPA is fair. In cases of disagreement with GPA, the expert consensus was usually progression. Access to GPA results after initial classification changed expert consensus in 11 of 100 cases.
