The Right

A 55-year-old man presented with sudden deterioration of vision in the right eye. His visual acuity was reduced to hand motion because of a large multilevel premacular hemorrhage. Nd:YAG laser was performed to drain the entrapped hemorrhage under the internal limiting membrane (ILM) and posterior hyaloid face in the macula into the vitreous. Immediately after laser treatment, streaming of red blood cells into the vitreous gel through the perforation site was observed. At the first-month follow-up, BCVA improved to 20/25 and ILM wrinkling was observed at the macula where the preretinal hemorrhage cleared. Fluorescein angiography revealed an isolated retinal venous macroaneurysm located on the macular branch of the superotemporal vein at the bifurcation site. In contrast to retinal arterial macroaneurysms, retinal venous macroaneurysms are quite rare. To the best of our knowledge, this is the first case reported with multilevel premacular hemorrhage caused by an isolated retinal venous macroaneurysm.

— Pseudomembranous trigonitis is a syndrome characterized by urgency, frequency, dysuria, bearing down and dyspareunia, with a typical endoscopic appearance and repeatedly negative urine culture examinations. Cystoscopically it appears as a white patch on the mucosal surface, usually well demarcated and often irregular in shape. The lesion may be finely granular in appearance and extend upward toward the ureteral orifices. Histologically it is a squamous not keratinizing metaplasia. Fifty-four female patients were treated with Nd:YAG laser photocoagulation at our Urologic Department from January 1994 to June 1995. Cystoscopic follow-up showed uniform riepithelization, with linear healing, undoubtedly contributing to the relief of symptoms. In our experience, laser treatment gave good and lasting relief of symptoms like no other therapies; so, high patient compliance, easy technique and good results make Nd:YAG laser photocoagulation highly effective in PMT management.

Final Treatment

Background: Infantile Café-Au-Lait Spot (CALS) is a benign hyperpigmentary skin disorder that ranges in color from light brown to dark brown. Using traditional laser therapies including 532nm potassium titanyl phosphate(KTP) laser, 694nm ruby laser and 755nm alexandrite laser for infantile CALS treatment may provoke harmful side effects such as purpurae, crusts,Post-Inflammatory Hyperpigmentation (PIH), mottled hypopigmentation and scarring. Unfortunately, there is no clear standard for the laser treatment of infantile CALS because an infant is too young to receive laser treatment. Objectives: This study was performed to investigate the efficacy and safety of Dr. Hoon Hur’s Golden Parameter Therapy (GPT) with a high fluence 1064nm Q-switched Nd:YAG laser laser (QSNL) for infantile CALS treatment. Methods: Nineteen Korean patients with infantile CALS were enrolled in this study and treated with a 1064nm QSNL on a weekly basis for 20-50 treatment sessions of Dr. Hoon Hur’s GPT. The parameters were a spot size of 7 mm, a fluence of 2.2 J/cm2 and a pulse rate of 10Hz with one pass by a sliding-stacking technique over the infantile CALS. Results: After the final treatment, all of the 19 patients with infantile CALS were achieved the complete removal of pigmented lesions without any side effects such as purpurae, crusts, PIH, mottled hypopigmentation or scarring. No recurrences were observed in any of the patients after a follow- up of 6-14 months. Conclusion: We suggest that Dr. Hoon Hur’s GPT with a high fluence 1064nm QSNL is a safe and effective treatment for infantile CALS without causing side effects and recurrences.

Purpose. The purpose of this report is to present a case who had spontaneous macular hole closure after Nd:YAG laser membranotomy applied to premacular haemorrhage associated with Valsalva retinopathy. Methods. Case report. Results. A 19-year-old young male patient presented to our clinic with sudden vision loss in his right eye, which had occurred 2 weeks before, following push-up and sit-up exercise. The patient was found to have premacular haemorrhage associated with Valsalva retinopathy. Nd:YAG laser membranotomy was performed. During his follow-up at week 1, full-thickness MH was observed and he was put under observation. At month 6, his vision acuity improved, laser coagulation sites in the fundus disappeared, and macular hole closed spontaneously. Conclusion. Macular hole that develops after Nd:YAG laser treatment of Valsalva retinopathy may spontaneously be closed like in our case. However, there is a need for further research to understand the mechanism of closure.

AbstractThere is a lack of treatment aimed at the regression of reticular pseudodrusen (RPD) secondary to age-related macular degeneration (AMD). The aim of this prospective, pilot study is to evaluate the safety and short-term efficacy of subthreshold laser treatment (SLT) in patients affected by RPD secondary to dry AMD (dAMD). Twenty eyes of 20 patients (mean age 78.4 ± 6.8 years) with RPD secondary to dAMD were prospectively enrolled. All patients were treated in an extrafoveal area of 1.27 mm2 using end-point management yellow subthreshold laser and followed for 3 months. Best-corrected visual acuity was 0.140 ± 0.09 LogMAR at the baseline and no changes were observed during the follow-up (p = 0.232). No significant worsening was disclosed before and after the treatment analyzing the macular sensitivity of the treated area (p = 0.152). No topical and/or systemic side effects were disclosed during the 3-month follow-up. The distribution among the RPD stages changed after the treatment (p < 0.001). In detail, in the treated area, we observed a significant increase in the number of Stage 1 RPD during the follow-up (p = 0.002), associated with a significant decrease of Stage 3 RPD (p = 0.020). Outer nuclear layer (ONL) thickness analysis showed a significant increase after the treatment associated with RPD regression (p = 0.001). End-point management SLT appears a safe treatment for RPD secondary to dAMD, showing short-term safety outcomes. Our results suggest that SLT could be effective in inducing a RPD regression in terms of RPD stage and ONL thickening.
