RESUMO
Purpose: Glaucoma is the second leading cause of blindness worldwide, affecting more than 64 million people aged 40–80. The best way to manage primary open?angle glaucoma (POAG) is by lowering the intraocular pressure (IOP). Netarsudil is a Rho kinase inhibitor, the only class of antiglaucoma medications that reorganizes the extracellular matrix to improve the aqueous outflow through the trabecular pathway. Methods: An open?label, real?world, multicentric, observation?based 3?month study was performed for assessing the safety and ocular hypotensive efficacy of netarsudil ophthalmic solution (0.02% w/v) in patients with elevated IOP. Patients were given netarsudil ophthalmic solution (0.02% w/v) as a first?line therapy. Diurnal IOP measurements, best?corrected visual acuity, and adverse event assessments were recorded at each of the five visits (Day?1: screening day and first dosing day; subsequent observations were taken at 2 weeks, 4 weeks, 6 weeks, and 3 months). Results: Four hundred and sixty?nine patients from 39 centers throughout India completed the study. The mean IOP at baseline of the affected eyes was 24.84 ± 6.39 mmHg (mean ± standard deviation). After the first dose, the IOP was measured after 2, 4, and 6 weeks, with the final measurement taken at 3 months. The percentage reduction in IOP in glaucoma patients after 3 months of once?daily netarsudil 0.02% w/v solution use was 33.34%. The adverse effects experienced by patients were not severe in the majority of cases. Some adverse effects observed were redness, irritation, itching, and others, but only a small number of patients experienced severe reactions, as reported in a decreasing order: redness > irritation > watering > itching > stinging > blurring. Conclusion: We found that netarsudil 0.02% w/v solution monotherapy when used as the first?line treatment in primary open?angle glaucoma and ocular hypertension was both safe and effective.
RESUMO
Purpose: To determine the stabilization of refraction at 2 weeks following MSICS by comparing the difference in spherical, cylindrical component and also spherical equivalent of refraction of 2 weeks follow-up with that of 6 weeks following surgery. Methods: The difference of spherical, cylindrical component and also spherical equivalent of refraction at 2 weeks and 6 weeks follow-up of 194 eyes that underwent uncomplicated MSICS with implantation of PMMA IOL conducted by a single experienced surgeon were compared to find out the amount of change and its significance was statistically tested by Wilcoxon-Signed Rank Test. Results: The difference in spherical power (0.04 � 0.30), cylinder power (0.03 � 0.40), and spherical equivalent (0.06 � 0.34) were very small and not significant statistically (P-value ?0.05). Conclusion: Necessary spectacle correction can safely be prescribed after 2 weeks following MSICS as subjective refraction stabilizes by that time without undergoing significant change. However, our observation was applicable in patients who had an uneventful cataract surgery without any risk factor, which can delay wound healing or cause poor visual outcome.
RESUMO
Purpose: To determine the effect of depth of scleral tunnel incision measured by anterior segment OCT on postoperative corneal astigmatism by comparing the change of magnitude of corneal astigmatism between superficial and deep sclerocorneal tunnel incision in manual small?incision cataract surgery (SICS). Methods: Depths of sclerocorneal incision of 72 eyes of patients undergoing uncomplicated manual SICS and attending regular follow?up schedule were assessed with anterior segment OCT at 6?week post?op follow?up. Results: The overall mean ± standard deviation (SD) change of astigmatism for superficial incision, that is, ?399 ?m, was 0.44 ± 0.30 and that for deeper, that is, ?400 ?m, was 0.13 ± 0.48 and the change was significantly higher in ?399 ?m group than in ?400 ?m group (P = 0.003). In both superior and temporal incision locations, the mean ± SD change of astigmatism for ?399 ?m incision was 0.48 ± 0.29 and 0.40 ± 0.30, respectively, and that for ?400 ?m was 0.03 ± 0.34 and 0.23 ± 0.57, respectively. The change of astigmatism was significantly higher in ?399 ?m incision group overall (P = 0.003) and also higher in both superior and temporal incision location groups (P = 0.001 and P = 0.479, respectively). Conclusion: The depth of sclerocorneal incision had a statistically significant effect on the change of astigmatism following manual SICS, with superficial incision (?399 ?m) causing a higher change than deeper incision (? 400 ?m).
