[Diagnostic Precision of the Confocal Scanning Laser Ophthalmoscopy in the Large Optic Disc with Physiological Excavation - a Long-Term Study]. / Diagnostische Zuverlässigkeit der konfokalen Scanning-Laser-Ophthalmoskopie bei großen Papillen mit physiologischer Exkavation ­ eine Langzeitstudie.

We repeatedly examined 17 subjects with presumed bilateral physiological excavation labeled as pathological and/or borderline via HRT to verify the diagnosis of physiological cupping or to monitor the long-term progression into normal tension glaucoma. PATIENTS AND METHODS: 17 Subjects with presumed bilateral physiological cupping and large optic discs were included in this long-term follow-up study. All subjects underwent regular detailed ophthalmologic examinations, including intraocular pressure measurement via Goldmann applanation tonometry (GAT), retinal nerve fiber layer imaging via optical coherence tonometry (OCT) and visual field testing and optic disc imaging using the HRT. Glaucomatous progression was identified using the HRT's tools (stereometric trend analysis [STA] and topographic change analysis [TCA]). RESULTS: In the initial examination, all 17 subjects were classified as "pathological", by the HRT's Moorfield's Regression Analysis (MRA). Over the observation period of 9.2 ± 5 years, only 1 of the 17 subjects showed an ensured conversion to normal tension glaucoma with glaucomatous visual field defects. The remaining 16 subjects show no visual field defects to date. STA showed significant changes in 3 subjects alone, in 1 subject TCA showed a significant change alone, and in 1 subject both analyses showed a progressive change. CONCLUSION: After 9 years of regular examinations, 16 of the 17 subjects that were classified as "pathological" using MRA showed no glaucomatous visual field defects. In 5 out of these 16 subjects, progressive changes of the optic disc could be recorded via HRT. Therefore, the diagnostic precision of the HRT measurements seems to be limited in patients with large discs and physiological cupping.

Three-Year Follow-Up of Trabeculectomy with 5-Fluorouracil.

PURPOSE: To evaluate the long-term outcome of trabeculectomy with intra- and postoperative 5-fluorouracil (5-FU) application in glaucoma. METHODS: Eighty-six patients with glaucoma planned for primary trabeculectomy with 5-FU and a minimum follow-up of 3 years were retrospectively analyzed. Success rates, postsurgical 5-FU injections, needling procedures, and complications were analyzed. RESULTS: Mean intraocular pressure (IOP) decreased from 27.2 ± 6.7 to 13.2 ± 4.2 mm Hg at 1 year and 13.8 ± 3.7 mm Hg at the 3-year follow-up. The complete success rates (no IOP-lowering medication) were 83, 79, 73, and 45% at 1 year for IOP ≤21, ≤18, ≤16, and ≤12 mm Hg, respectively, and 64, 59, 56, and 20% for these criteria at 3 years. The average number of medications decreased from preoperatively 2.9 ± 1.4 to 0.2 ± 0.5 at 1 year and 0.7 ± 1.1 at 3 years. During the first 6 months, subconjunctival 5-FU injections were performed in 49 cases. Eleven patients underwent bleb needling during the first 6 months and 13 patients underwent the procedure between the 6th month and the 3rd year. Malignant glaucoma and bleb-related endophthalmitis occurred in 1 patient each. CONCLUSIONS: Trabeculectomy with 5-FU is an efficient surgical procedure for glaucoma treatment when combined with intensified postsurgical care.

Worldwide Argus II implantation: recommendations to optimize patient outcomes.

BACKGROUND: A position paper based on the collective experiences of Argus II Retinal Prosthesis System investigators to review strategies to optimize outcomes in patients with retinitis pigmentosa undergoing retinal prosthesis implantation. METHODS: Retinal surgeons, device programmers, and rehabilitation specialists from Europe, Canada, Middle East, and the United States were convened to the first international Argus II Investigator Meeting held in Ann Arbor, MI in March 2015. The recommendations from the collective experiences were collected. Factors associated with successful outcomes were determined. RESULTS: Factors leading to successful outcomes begin with appropriate patient selection, expectation counseling, and preoperative retinal assessment. Challenges to surgical implantation include presence of staphyloma and inadequate Tenon's capsule or conjunctiva. Modified surgical technique may reduce risks of complications such as hypotony and conjunctival erosion. Rehabilitation efforts and correlation with validated outcome measures following implantation are critical. CONCLUSIONS: Bringing together Argus II investigators allowed the identification of strategies to optimize patient outcomes. Establishing an on-line collaborative network will foster coordinated research efforts to advance outcome assessment and rehabilitation strategies.
