To report a single case of improvement on choroidal metastasis of breast cancer after laser photocoagulation. A 52-year-old female patient who complained of visual disturbance of the right eye with multiple states of metastasis of breast carcinoma. On initial examination, the right best-corrected visual acuity was 0.63. Right fundoscopy revealed an elevated mass-like lesion temporal to the macule with serous retinal detachment. The mass had a 3.5-disc diameter. A right fluorescein angiogram revealed hypofluorescence during the prearterial and arteriovenous phase and hyperfluorescence during the venous phase. The venous phase showed almost total masking of background choroidal fluorescence at the elevated lesion because of leakage and neovascularization. The patient was treated 4 times by diode laser photocoagulation in addition to chemotherapy. Fifty days after the diode laser treatments, the funduscopy examination and fluorescein angiogram revealed that the serous retinal detachment had been absorbed, the choroid had become flat, the lesion had been reduced in size and hyperfluorescence. The right best-corrected visual acuity was improved to 0.8. Laser photocoagulation appears not to cause any problems for the patient and may be an efficient treatment for patients with choroidal breast carcinoma.

OBJECTIVETo evaluate the curative effects of diode laser coagulation on grade III internal hemorrhoids.
METHODSFrom March 2004 to December 2004, 86 patients with grade III internal hemorrhoids were divided into two groups, received laser coagulation (laser group, n=46) or received hemorrhoidectomy (control group, n=40). Complications, symptom relief, pain scores and satisfaction scores were compared between the two groups six months after operation.
RESULTSPain scores were lower in laser group than that of the control group on the first day and seventh day after operation. Small amount of bleeding occurred in the laser group (12 cases) and control group (35 cases), however, non of them required special hemostasis. Laser coagulation and closed hemorrhoidectomy were equally effective in controlling symptomatic prolapse. There was no difference in terms of continence scores and patients satisfaction between the two groups (P> 0.05).
CONCLUSIONSDiode laser coagulation can be considered as a safe and effective procedure for the treatment of grade III hemorrhoids.

PURPOSE: This pilot study aimed to evaluate the efficacy and safety of subthreshold micropulse yellow (577-nm) laser photocoagulation (SMYLP) in the treatment of diabetic macular edema (DME). METHODS: We reviewed 14 eyes of 12 patients with DME who underwent SMYLP with a 15% duty cycle at an energy level immediately below that of the test burn. The laser exposure time was 20 ms and the spot diameter was 100 microm. Laser pulses were administered in a confluent, repetitive manner with a 3 x 3 pattern mode. RESULTS: The mean follow-up time was 7.9 ± 1.6 months. The baseline-corrected visual acuity was 0.51 ± 0.42 logarithm of the minimum angle of resolution (logMAR), which was improved to 0.40 ± 0.35 logMAR (p = 0.025) at the final follow-up. The central macular thickness at baseline was 385.0 ± 111.0 microm; this value changed to 327.0 ± 87.7 microm (p = 0.055) at the final follow-up. CONCLUSIONS: SMYLP showed short-term efficacy in the treatment of DME and did not result in retinal damage. However, prospective, comparative studies are needed to better evaluate the efficacy and safety of this treatment.

Objective:
To compare the clinical effect of diode laser enucleation of the prostate (DIOD) with that of transurethral resection of the prostate (TURP) on benign prostate hyperplasia (BPH) with different prostate volumes.
METHODS:
This retrospective study included 256 BPH patients treated by DIOD (n = 141) or TURP (n = 115) from March 2012 to August 2015. According to the prostate volume, we divided the patients into three groups: <60 ml (42 for DIOD and 31 for TURP), 60-80 ml (51 for DIOD and 45 for TURP), and >80 ml (48 for DIOD and 39 for TURP). We obtained the relevant data from the patients before, during and at 6 months after surgery, and compared the two surgical strategies in operation time, perioperative levels of hemoglobin and sodium ion, post-operative urethral catheterization time and bladder irrigation time, pre- and post-operative serum PSA levels, International Prostate Symptoms Score (IPSS), post-void residual urine (PVR) volume and maximum urinary flow rate (Qmax), and incidence of post-operative complications among different groups.
RESULTS:
In the <60 ml group, there were no remarkable differences in the peri- and post-operative parameters between the two surgical strategies. In the 60-80 ml group, DIOD exhibited a significant superiority over TURP in the perioperative levels of hemoglobin ([3.25 ± 1.53] g/L vs [4.77 ± 1.67] g/L, P <0.05) and Na+ ([3.58 ± 1.27]mmol/L vs [9.67 ± 2.67] mmol/L, P <0.01), bladder irrigation time ([30.06 ± 6.22]h vs [58.32 ± 10.25] h, P <0.01), and urethral catheterization time ([47.61 ± 13.55] h vs [68.01 ± 9.69] h, P <0.01), but a more significant decline than the latter in the postoperative PSA level ([2.34 ± 1.29] ng/ml vs [1.09 ± 0.72] ng/ml, P <0.05), and similar decline was also seen in the >80 ml group ([3.35 ± 1.39] ng/ml vs [1.76 ± 0.91] ng/ml, P <0.05). No blood transfusion was necessitated and nor postoperative transurethral resection syndrome or urethral stricture observed in DIOD. However, the incidence rate of postoperative pseudo-urinary incontinence was significantly higher in the DIOD (22.7%, 32/141) than in the TURP group (7.83%, 9/115) (P <0.05).
CONCLUSIONS
DIOD, with its obvious advantages of less blood loss, higher safety, faster recovery, and more definite short-term effectiveness, is better than TURP in the treatment of BPH with medium or large prostate volume and similar to the latter with small prostate volume.
