RESUMO

BACKGROUND: Complete removal of the cortex has been advocated to prevent posterior capsular opacification but carries the risk of zonular dehiscence, hence there is a need for a safe maximal cortical cleanup technique in eyes with severe diffuse zonulopathy in subjects above age 90. METHODS: We used bimanual central cortical cleaning by elevating central fibers and aspirating them toward the periphery. Peripheral cortical fibers were removed passively only when they became loose due to copious irrigation. A one-piece foldable implant was inserted without a capsular tension ring. Postoperative corticosteroid drops were used. RESULTS: This technique was safely performed in a dozen eyes with severe pseudo-exfoliation or brunescent cataract with weak zonules. Posterior capsular rupture, iritis, vitreous loss, and lens subluxation were not observed. Moderate capsular phimosis occurred but with maintained central vision. CONCLUSION: The dogma of "complete cortical cleanup" in severe zonulopathy needs to be revisited in favor of a clear visual axis with maximal preservation of the damaged zonules. This technique is ideal in patients above age 90 where posterior capsular opacification and late dislocation of intraocular lens-capsule bag complex are unlikely to occur until several years postoperatively.

RESUMO

PURPOSE: In vitro and in vivo studies did not detect toxicity to the retinal pigment epithelium cells using intravitreal ziv-aflibercept. Our purpose is to ascertain the 3-month safety and efficacy in wet age-related macular degeneration (AMD) treated with intravitreal ziv-aflibercept. METHODS: Prospectively, consecutive patients with wet AMD underwent ziv-aflibercept intravitreal injection (1.25 mg/0.05 mL) from March 2015 to November 2015. Monitoring of best-corrected visual acuity, intraocular inflammation, cataract progression and by spectral domain optical coherence tomography were carried out at baseline day 1, 1 week, 1 month, 2 months and 3 months after injections. RESULTS: 30 eyes were treated (22 Caucasians, 8 Indians; 16 men, 14 women; 14 right eyes and 16 left eyes) with mean age of 74.3 years with 11 treatment-naïve cases and 19 having had treatment-non-naïve. Best-corrected visual acuity improved from baseline logMAR 1.08-0.74 at 1 week, 0.72 at 1 month, 0.67 at 2 months and 0.71 at 3 months (p<0.001 for all time periods). Central macular thickness in microns decreased from 332.8 to 302.0 at 1 week, 244.8 at 1 month, 229.0 at 2 months and 208.2 at 3 months (p<0.001 for all time periods). There were no signs of intraocular inflammation, or change in lens status or increase in intraocular pressure throughout the study. CONCLUSIONS: Off label use of ziv-aflibercept improves visual acuity, without detectable ocular toxicity and offers a cheaper alternative to the same molecule aflibercept, especially in low/middle-income countries and in countries where aflibercept (Eylea) is not available. TRIAL REGISTRATION NUMBER: NCT02486484.

RESUMO

PURPOSE: To evaluate the short-term efficacy of intravitreal adalimumab (IVA) for the treatment of eyes with active noninfectious uveitis. METHODS: Consecutive eyes with active noninfectious uveitis were injected with IVA at 0, 2, then every 4 weeks for total of 26 weeks. RESULTS: Six out of 7 patients (12 of 13 eyes) completed 26 weeks of treatment. One patient (1 eye) failed treatment. Seven out of 12 eyes had improvement of ≥2 ETDRS lines. Three out of three eyes had resolution of anterior chamber cells. And 9 of 10 eyes with vitreous haze had zero haze at 26 weeks. Five out of 8 eyes with macular edema had complete resolution. Median fluorescein angiography score improved from 14 to 4 on last follow-up. CONCLUSIONS: IVA was effective in controlling the inflammation, decreasing the macular edema, and improving the best corrected visual acuity in the majority of eyes in this series.

RESUMO

A 20-year-old woman, a registered nurse, presented with best-corrected visual acuity of 6/15 (20/50) due to bilateral extensive persistent pupillary membrane. Sequential argon laser photocoagulation of the iris strands at the pupillary membrane iris collarette followed by neodymium:YAG laser lysis resulted in partial clearing of the central visual axis without bleeding. Best-corrected visual acuity improved to 6/9 (20/30) bilaterally without complications noted 1 year after combined laser therapy.

RESUMO

BACKGROUND AND OBJECTIVE: Nonmydriatic fundus photography (FP) has been a suboptimal tool for detecting age-related macular degeneration (AMD) changes. This study sought to enhance the detection of AMD changes by combining nonmydriatic FP with nonmydriatic spectral-domain optical coherence tomography (SD-OCT). PATIENTS AND METHODS: The study population included 249 patients aged 65 years and older who were assessed for AMD changes using standard mydriatic biomicroscopic fundus examination. Each eye then underwent nonmydriatic FP in one session followed 1 week later with nonmydriatic FP coupled with nonmydriatic SD-OCT. Images were interpreted for detection of AMD changes, and findings were compared to the original mydriatic biomicroscopic examination. RESULTS: Nonmydriatic FP had 64% sensitivity, 97% specificity, and a kappa value of 0.67 in detecting AMD changes compared with the traditional mydriatic biomicroscopic examination. Combined nonmydriatic FP and nonmydriatic SD-OCT increased sensitivity to 91.5%, specificity to 98.6%, and kappa to 0.91. CONCLUSION: The addition of nonmydriatic SD-OCT to nonmydriatic FP enhances the detection of AMD changes.
