Comparative evaluation of Latanoprostene Bunod, Timolol Maleate, and latanoprost Ophthalmic Solutions to assess their safety and efficacy in lowering intraocular pressure for the management of Open-Angle Glaucoma

OBJECTIVES: Timolol maleate has been reported to be a safer intraocular pressure (IOP) lowering treatment than latanoprost. The United States Food and Drug Administration approved latanoprostene bunod, a nitric oxide-donating prodrug of latanoprost, for lowering IOP. This study compared the safety and efficacy of latanoprost, latanoprostene bunod, and timolol maleate in patients with open-angle glaucoma. METHODS: Patients who received latanoprost eye drops once daily in the evening were included in the latanoprost Ophthalmic Solutions (LP) cohort (n=104). Those who received latanoprostene bunod eye drops once daily in the evening were included in the Latanoprostene Bunod (LB) cohort (n=94). Those who received timolol eye drops twice daily were included in the Timolol Maleate (TM) cohort (n=115). All treatments were administered to the affected eye(s) for 3 months. Informed Consent has been taken from each participant before the trial. RESULTS: At the end of 3 months of treatment, latanoprost, latanoprostene bunod, and timolol were all successful in reducing IOP. The LB cohort had the highest reduction in IOP, compared to the LP and TM cohorts. All treatments had some common adverse ocular effects. CONCLUSION: Latanoprostene bunod was superior to latanoprost and timolol for the treatment of open-angle glaucoma.

Application of "tennis racket" flap with fascial pedicle on the healthy chest for the radiation ulcer after surgical treatment of breast carcinoma / 中华整形外科杂志

<p><b>OBJECTIVE</b>To introduce the application of "tennis racket" flap with fascial pedicle on the healthy chest for radiation ulcer after surgical treatment of breast cancer.</p><p><b>METHODS</b>The " tennis racket" flap was designed on the healthy chest along the cartilage with fascia pedicle near the sternum. 9 cases were treated. The flaps size ranged from 5.0 cm x 3.5 cm to 13 cm x 11 cm with pedicle size of 2-8 cm in length and 2.0-3.0 cm in width.</p><p><b>RESULTS</b>All the 9 flaps survived completely with satisfactory appearance. The patients were followed up for 2 months to 3 years without ulcer reoccurrence.</p><p><b>CONCLUSIONS</b>The "tennis racket" flap has a slender fascial pedicle without major blood vessel. It has the advantages of good flexibility for rotation and large flap size for the reconstruction of the radiation ulcer after surgical treatment of breast cancer.</p>

Effect of Laser in situ Keratomileusis on Accommodation / 华中科技大学学报（医学）（英德文版）

Summary: The accommodative function before and after laser in situ keratomileusis (LASIK) was observed, and the effect of LAS IK on accommodation was investigated. In a prospective clinical trial,48 myopic patients (96 eyes) subject to bilateral LASIK in Refractive Surgery Center, Tongji Hospital, Tongii Medical College, Huazhong University of Science and Technology (China) from March 2006 to June 2006 were selected and studied. Refractions, accommodative range, amplitude of accommodative response and high frequency component (HFC) of accommodative microfluctuations were measured with NEDIK-730A before and one week and 30 days after operation. Dominant and non-dominant eyes were determined by hole-in-card method. It was found that all of the operative eyes showed an uncorrected visual acuity of 0.8 or better one week postoperatively, and 1.0 or better 30 days postoperatively. Compared with those preoperatively, accommodative range and HFC had no significant difference at first week and 30th day after operation in both dominant eyes and non-dominant eyes (P0.05), but there was a significant difference in the amplitude of accommodative response/accommodative stimulus ratio (A/S) after operation (P<0.01), and no significant difference was found in' accommodation between one week and 30 days postoperation. No ocular dominance's change was noted. There was no significant difference in accommodative function between dominant eyes and non-dominant eyes. It was suggested that LASIK produced no significant effect on accommodation.
