Experience with netarsudil 0.02% and latanoprostene bunod 0.024% as adjunctive therapy for glaucoma.

PURPOSE: To assess the effectiveness and safety of adjunctive topical netarsudil 0.02% and latanoprostene bunod 0.024% in patients with glaucoma. METHODS: A retrospective, multi-center, cohort study of patients with glaucoma treated with netarsudil 0.02% or latanoprostene bunod from five tertiary care centers. Inclusion criteria included patients with glaucoma treated with either medication as adjunctive therapy. Outcomes included mean absolute intraocular pressure (IOP) reduction and relative IOP reduction from baseline. Adverse reactions and reasons for discontinuation were reported. One-way analysis of variance, Kruskal-Wallis rank sum test, and Mann Whitney U test compared the outcomes. RESULTS: A total of 95 eyes (95 patients) on netarsudil and 41 eyes (41 patients) on latanoprostene bunod were analyzed. Mean duration of use was 54.3 ± 28 days for netarsudil and 82.9 ± 51.2 days for latanoprostene bunod. At the final visit, mean IOP reduction was 3.9 ± 4.6 mmHg (17.5 ± 6.0%) (p < 0.0001) with netarsudil and 2.9 ± 3.7 mmHg (13.6 ± 16.3%) (p < 0.0001) with latanoprostene bunod. IOP lowering did not depend on baseline number of IOP-lowering medications. The most common reason for discontinuation was non-effectiveness in both groups. CONCLUSION: Similar to monotherapy, netarsudil and latanoprostene bunod demonstrated efficacy in lowering IOP when used as adjunctive therapy.

Angle-closure glaucoma in teenagers.

OBJECTIVE: To report the occurrence of angle-closure glaucoma in 2 teenagers. DESIGN: Observational case reports, review of literature. METHODS: Review of case histories, examinations, biometries, visual fields, and ultrasound biomicroscopy findings in 2 teenagers with angle-closure glaucoma. MAIN OUTCOME MEASURES: Intraocular pressure, gonioscopy, Humphrey 24-2 visual field (SITA Standard), and ultrasound biomicroscopy. RESULTS: The first case involved a 15-year-old white male who presented with an intraocular pressure of 60 mm Hg in the right eye and 24 mm Hg in the left eye and 360-degree appositional closure in both eyes. Ultrasound biomicroscopy revealed prominent bilateral ciliary pigment epithelial cysts pushing the iris anteriorly towards the angle. The second case involved a 14-year-old white male with a strong family history of primary angle-closure glaucoma. The patient had pupillary block and an intraocular pressure of 24 mm Hg in the right eye and 40 mm Hg in the left eye on routine eye examination. Gonioscopy and ultrasound biomicroscopy revealed appositional closure of the angle in all 4 quadrants bilaterally. CONCLUSION: Primary angle-closure glaucoma is uncommon in younger individuals. Therefore, the finding of angle-closure glaucoma in a young individual should alert the physician to the possibility of a secondary cause of angle closure, such as iris pigment epithelial cysts. In addition, special attention to family history is important as the configuration of an occludable anterior chamber angle may, in some instances, be inherited.

Comparison of contrast sensitivity, visual acuity, and Humphrey visual field testing in patients with glaucoma.

BACKGROUND: Despite their normal or near-normal Snellen visual acuity, patients with glaucoma often complain of "poor" vision. OBJECTIVE: To investigate the relationship between large-letter contrast sensitivity, high-contrast visual acuity, and visual field defects in patients with glaucoma who have 20/40 or better visual acuity. DESIGN: Prospective, cross-sectional case series. PATIENTS AND METHODS: We evaluated 250 eyes of 144 subjects from the Glaucoma Service at the University of Illinois at Chicago College of Medicine. Subjects with a diagnosis of glaucoma, suspected glaucoma, or ocular hypertension who met the 20/40 or better vision requirement were recruited. Visual acuity was measured using the rear-illuminated Lighthouse Visual Acuity Chart at 4 m. Contrast sensitivity was measured using the Pelli-Robson Chart in a front-illuminated box with even luminance across the chart. Visual fields of the patients were measured using the 24-2 full-threshold program on the Humphrey Visual Field Analyzer. RESULTS: A significant correlation (r = 0.57, P < 0.001, n = 127) was found between the visual field mean deviations and the contrast sensitivity scores. The correlation (r = -0.322, P < 0.001, n = 127) was less between the visual field mean deviation and the log MAR visual acuity values, as was the correlation between the contrast sensitivity scores and log MAR visual acuity values (r = -0.370, P < 0.001, n = 127). In the subgroup of patients with chronic open-angle glaucoma, the correlation between the mean visual field deviation and the contrast sensitivity score was higher at 0.689 (P < or = 0.001, n = 62). CONCLUSIONS: Reduced contrast sensitivity is significantly correlated with visual field losses in patients with glaucoma and a visual acuity of 20/40 or better. The study data support the conclusion that, compared with visual acuity, the disease process preferentially affects contrast sensitivity. In our previous work, contrast sensitivity was shown to be more related than visual acuity to real-world function in patients with early glaucomatous changes.

Predictors for success of needle revision of failing filtration blebs.

OBJECTIVE: To assess the factors that can predict the success of external needle revision of failing blebs. DESIGN: Retrospective, nonrandomized, comparative case series. PARTICIPANTS: Forty-nine eyes of 43 patients who underwent a needle revision of a filtration bleb with 5-fluourouracil (5-FU) by one physician (SVLB) between August 1993 and December 1994. INTERVENTION: Needle revision of a failing filtration bleb using 5-FU. MAIN OUTCOMES: The intraocular pressure, glaucoma medications, and any complications. RESULTS: The risk ratio of fornix-based trabeculectomies compared with limbus-based trabeculectomies was 3.781; P = 0.047. The risk ratios for gender, race, type of glaucoma, lens status, previous surgery, antimetabolite used for the initial trabeculectomy, and preoperative bleb characteristics were not statistically different for any one group. CONCLUSIONS: Fornix-based trabeculectomies were more likely to fail the needle revisions compared with limbus-based trabeculectomies. None of the five preneedling bleb characteristics showed a propensity toward success or failure. Other demographics such as gender, race, type of glaucoma, previous surgery, antimetabolite used for the initial trabeculectomy, and lens status were also not predictive for success.
