ABSTRACT

PURPOSE: To report a rare case of an intraretinal tuberculoma and associated neuroretinitis. METHODS: The patient was evaluated with various imaging modalities including fundus photography, fluorescein angiography, magnetic resonance imaging, and optical coherence tomography; her extensive laboratory workup returned positive for tuberculosis. RESULTS: After initially presenting with no light perception, 13 weeks of antitubercular therapy allowed for visual acuity recovery to 20/30. CONCLUSION: We demonstrate the spectral domain optical coherence tomography characteristics of an intraretinal tuberculoma.

ABSTRACT

PURPOSE: To examine how indications, patient characteristics, and outcomes differ between anterior and posterior approaches of endoscopic cyclophotocoagulation (ECP) in the treatment of glaucoma. METHODS: This is a retrospective chart review of 9 anterior and 20 posterior ECP cases (n = 29). RESULTS: Posterior ECP cases were typically associated with a dramatic increase in intraocular pressure (IOP), whereas the anterior ECP was associated with chronically elevated pressures. The initial IOPs in mm Hg of posterior ECP cases (26.8 non-NVG; 35.2 NVG) were much greater than anterior ECP cases (17.8), and a greater overall reduction in IOP was observed in the posterior versus anterior ECP cases (10.3 posterior non-NVG; 21.3 posterior NVG; 3.6 anterior, P < .001). With procedural success defined as 6-month post-operative IOP falling within normal ranges and a decrease in either IOP or number of prescribed glaucoma medications, the success rate of ECP was 92% for posterior NVG, 89% for anterior and 75% for posterior non-NVG cases (P = .34), similar to the previous literature. Of the four unsuccessful cases, two resulted in a normal IOP but lacked a drop in pressure or reduction in medication burden, one resulted in a 6-point drop in IOP but remained at 23 mm Hg, and one resulted in phthisis bulbi (3%) from an initial pressure above 40 mm Hg. CONCLUSION: Endoscopic cyclophotocoagulation is an effective and safe procedure for severe glaucoma cases from both an anterior and posterior approach. Ophthalmologists should consider this procedure as part of their glaucoma treatment arsenal.

ABSTRACT

We describe clinical applications and surgical techniques for a new type of capsular tension segment (CTS) for use during cataract surgery. The Ambati CTS is distinguished from other CTS devices by having 2 eyelets close to each other, which allows it to distribute tension to 2 points, avoiding too much stress at a single point on the anterior capsulotomy, which prevents peaking of the capsulorhexis, and potentially reducing the risk for anterior capsule tear. Two of these CTS devices could possibly be used to provide 4-point fixation of a capsular bag in eyes with near-complete zonular instability. We describe 4 cases and 2 surgical techniques for implanting the new CTS, 1 technique in an adult patient with zonular weakness secondary to trauma and the other in 3 children with subluxated lenses due to Marfan syndrome.

ABSTRACT

PURPOSE: To determine whether intraocular lens (IOL) type affects patient driving habits 6 months to 5 years after cataract surgery, and to determine whether there were differences in self-reported driving habits between patients who received 1 of 2 IOLs. SETTING: John A. Moran Eye Center, University of Utah, Salt Lake City, Utah, USA. DESIGN: Retrospective case series. METHODS: Patients completed a telephone-administered Driving Habits Questionnaire (DHQ) 6 months to 5 years after having bilateral cataract surgery with a single-piece hydrophobic acrylic IOL, SN60WF (Group 1) or ZCB00 IOL (Group 2), in both eyes. RESULTS: The study comprised 260 patients (130 in each IOL group). Of these, 117 in Group 1 and 114 in Group 2 were still active drivers. The DHQ response differences for each IOL group did not reach statistical significance, except for self-rated quality of driving and difficulties with driving at night. For these significant differences, contradictory results were found. CONCLUSIONS: Patients with either of the monofocal IOLs had similar self-reported driving habits after bilateral cataract surgery. The choice of IOL did not affect patients' postoperative driving habits.

ABSTRACT

A biomarker can be a substance or structure measured in body parts, fluids or products that can affect or predict disease incidence. As age-related macular degeneration (AMD) is the leading cause of blindness in the developed world, much research and effort has been invested in the identification of different biomarkers to predict disease incidence, identify at risk individuals, elucidate causative pathophysiological etiologies, guide screening, monitoring and treatment parameters, and predict disease outcomes. To date, a host of genetic, environmental, proteomic, and cellular targets have been identified as both risk factors and potential biomarkers for AMD. Despite this, their use has been confined to research settings and has not yet crossed into the clinical arena. A greater understanding of these factors and their use as potential biomarkers for AMD can guide future research and clinical practice. This article will discuss known risk factors and novel, potential biomarkers of AMD in addition to their application in both academic and clinical settings.
