Purpose/Objective. To evaluate the effectiveness of combined phacoemulsification, viscogoniosynechialysis (VGSL), and endocyclophotocoagulation (ECP) in patients with moderate chronic angle-closure glaucoma (CACG) with peripheral anterior synechia (PAS) ≥90 not controlled with glaucoma medications and previous iridotomy yag laser. Materials and Methods. We retrospectively reviewed records from patients with cataract and uncontrolled chronic angle-closure glaucoma despite maximal tolerated medical therapy and iridotomy yag laser who received combined treatment with phacoemulsification with posterior capsular lens implantation, VGSL, and ECP 360°. We evaluated intraocular pressure (IOP), glaucoma medications, and best corrected visual acuity (BCVA) preoperatively and during follow-up.Results. A total of 29 eyes from 22 patients received surgical intervention. Mean follow-up was 6 months. Mean preoperative IOP was 18.2 mmHg, and postoperatively, IOP was 13.5, 12.2, and 12.8 mmHg at 1, 3, and 6 months, respectively. Complete success was 37.9%, and relative success was 72.4%. Mean BCVA was 0.4 logMAR preoperative and 0.3 logMAR 6 months after surgery. Glaucoma medication fell significantly from 2.34 ± 1.66 preoperatively to 1.31 ± 2.6 postoperatively p<0.001. Overall, 44.8% of the patients did not require glaucoma medications at 6 months. There were no visual significant complications. Conclusion. Combined treatment with phacoemulsification with posterior capsular lens implantation, VGSL, and ECP is effective and safe in reducing IOP and number of glaucoma medications with stable BCVA at 6 months.

Invention of the Q-switch advanced laser method is the most effective methods of tattoo removal compared to other methods of i.e. chemical, mechanical and surgical. In this study, we are reporting black pigment tattoo removal by comparing two wavelengths 532 nm and 1064 nm of Q-switched Nd-YAG laser. Using a single-pulse laser at 1064 nm wavelength, the maximum laser fluence for skin damage is 3.04 J/cm2 with pulse energy 0.55 J. While, at 532 nm wavelength, maximum laser fluence is 0.5 J/cm2 with pulse energy 0.42 J at 8-10 ns for tattooed skins. Moreover, after 1064 nm and 532 nm laser irradiations, skin biopsy of black tattooed rat’s skin demonstrates the ink granules local redistribution. Microscopic study indicates that black ink particles become smaller and vanished from the skins after 1064 nm laser treatment. The findings of this study indicate that 1064 nm wavelengths of Q-switched Nd-YAG laser treatment with 0.55 J pulse energy, is one of the significant methods of black tattoo removal with remarkable differences.

Introduction: Melasma is one of the most common skin pigmentation disorders, which mostly affects the facial skin and has a considerable psychological impact on the patients. Melasma management has been one of the controversial issues in dermatology. We aimed to compare the combined treatment of the Er: YAG (erbium: yttrium–aluminum–garnet) laser plus hydroquinone (HQ) 4% with HQ 4% alone in the treatment of melasma. Methods: Twenty-nine patients were treated with the combined Er: YAG laser and HQ 4% on one side of the face with HQ 4% alone on the other side. Three sessions of the laser rat 4-week intervals. The outcome was calculated using the Melasma Area Severity Index (MASI). Results: The side that received the combined treatment (laser + HQ 4%) showed a statistically significant reduction in MASI compared to the side treated with HQ 4% alone. Conclusion: Our study suggests the superiority of the combination of the Er: YAG laser and HQ 4% in the treatment of melasma compared to HQ 4% alone.

Case Note Review

Purpose. The purpose of this study was to assess the efficacy and safety of intraocular direct cyclophotocoagulation (IDCP) using a 532 nm laser with combination treatment in reducing intraocular pressure (IOP) for patients with advanced neovascular glaucoma (NVG) with angle closure. In addition, we sought to determine the success rate and frequency of complications and explore an optimized solution to reduce the number of topical medications and the pain of patients. Methods. A retrospective case note review of all patients undergoing combined treatment including IVR, phaco, PPV, PRP, and IDCP from January 2017 to June 2018. Results. In total, 24 consecutive patients (25 eyes) were reviewed. The mean IOP was significantly decreased from 42.2 ± 8.5 mmHg preoperatively to 15.56 ± 2.0 mmHg ( P < 0.0001 ), and no neovascularization of the iris (NVI) reoccurred at month 18. The number of medications used was reduced from 2.72 ± 0.45 preoperatively to 0.87 ± 0.40 at month 18 ( P < 0.0001 ). Conclusions. During 18 months of follow-up, the combined treatments were safe and had a significant IOP-lowering effect. This study provides a new method of performing IDCP with a 532 nm laser, allowing for the use of internal cyclophotocoagulation without extra equipment.
