Non-Traumatic Open Globe Injuries: Presenting Characteristics And Visual Outcomes, Andrew W Gross, James Z Fan, Margaret L Pfeiffer, Alice Z Chuang, Karina Richani, Eric L Crowell

Faculty, Staff and Student Publications

Purpose: To describe clinical characteristics and visual outcomes of non-traumatic open globe injuries.

Setting: A level 1 trauma centre in a large urban medical centre.

Design: Retrospective study.

Methods: Charts of non-traumatic open globe patients admitted to MHH-TMC from 1/2010 to 3/2015 were reviewed for demographics, cause, clinical characteristics, visual acuity (VA) and enucleation.

Results: Thirty eyes were included: 15 (50%) were males with a mean age of 47 (±28) years. All presented with zone 1 injury. Twenty-five (83%) had a perforated corneal ulcer. Presenting VA was count fingers (n = 3, 10%) to NLP (n = 6, 20%). Twenty-four …

Wide Range Of Phenotypic Severity In Individuals With Late Truncations Unique To The Predominant Cdkl5 Transcript In The Brain, Laura Keehan, Isabel Haviland, Yoel Gofin, Lindsay C Swanson, Christelle Moufawad El Achkar, John Schreiber, Grace E Vannoy, Emily O'Heir, Anne O'Donnell-Luria, Richard Alan Lewis, Pilar Magoulas, Alyssa Tran, Mahshid S Azamian, Hsiao-Tuan Chao, Lisa Pham, Rodney C Samaco, Sarah Elsea, Erin Thorpe, Akanchha Kesari, Denise Perry, Brendan Lee, Seema R Lalani, Jill A Rosenfeld, Heather E Olson, Lindsay C Burrage

Cyclin-dependent kinase-like 5 (CDKL5) deficiency disorder (CDD) is caused by heterozygous or hemizygous variants in CDKL5 and is characterized by refractory epilepsy, cognitive and motor impairments, and cerebral visual impairment. CDKL5 has multiple transcripts, of which the longest transcripts, NM_003159 and NM_001037343, have been used historically in clinical laboratory testing. However, the transcript NM_001323289 is the most highly expressed in brain and contains 170 nucleotides at the 3' end of its last exon that are noncoding in other transcripts. Two truncating variants in this region have been reported in association with a CDD phenotype. To clarify the significance and range …

Bilateral, Full-Thickness Macular Holes While Undergoing Chemotherapy, Sarah Dieter Od, Brett Garee Od Ms, Susan Zacatelco Od, Julie Henry Od

Optometric Clinical Practice

Background: Bilateral, full-thickness macular holes are a rare condition that can substantially affect quality of life. Macular hole diagnosis and treatment is key for these patients.

Case Report: A 71 year old Caucasian male presented with a chief complaint of distance blur in both eyes, worsening over the past 1-2 weeks. He had no diagnosis of diabetes. He added that his prostate cancer had spread and that his last treatment ended 9 days ago. He was ultimately diagnosed with bilateral, full-thickness macular holes. Referral to a retinal specialist for surgical management yielded good results.

Conclusion: This is …

Isolated Optic Neuropathy As The Presenting Sign Of Neurosyphilis, Kasey Zann Od, Molly Johnson Od, James Fabian Od

Optometric Clinical Practice

Background: Detection and treatment of syphilitic ocular disease without a known history of syphilis is often difficult due to its varied presentations. Early diagnosis and treatment are the key to reducing risk of permanent vision loss, particularly with optic nerve and retinal manifestations.

Case Report: This case report describes a 44 year-old male who was diagnosed with neurosyphilis through his work-up for unilateral optic neuropathy.

Conclusion: This report illustrates the importance of including syphilis lab testing in the setting of optic nerve edema. Syphilis should be considered in any inflammatory ocular disease, especially in patients with atypical presentations and high-risk …

Selectively Targeting Disease-Restricted Secretogranin Iii To Alleviate Choroidal Neovascularization, Liyang Ji, Prabuddha Waduge, Lili Hao, Avinash Kaur, Wencui Wan, Yan Wu, Hong Tian, Jinsong Zhang, Keith A Webster, Wei Li

Choroidal neovascularization (CNV), a leading cause of blindness in the elderly, is routinely treated with vascular endothelial growth factor (VEGF) inhibitors that have limited efficacy and potentially adverse side effects. An unmet clinical need is to develop novel therapies against other angiogenic factors for alternative or combination treatment to improve efficacy and safety. We recently described secretogranin III (Scg3) as a disease-selective angiogenic factor, causally linked to diabetic retinopathy and acting independently of the VEGF pathway. An important question is whether such a disease-selective Scg3 pathway contributes to other states of pathological angiogenesis beyond diabetic retinopathy. By applying a novel …
