Recently, we have experienced case of juxtapapillary retinal angioma. This patient was a 32-year-old Korean woman who visited our hospital because of blurred vision in her left eye for about 20 days. At the time of examination, the visual acuity of this eye was 0.3. Ophthalmoscopic examination revealed a sherical, highly vascularized tumor at the temporal margin of the optic papilla and peripapillary retinal exudates. This case was presented with a brief review of the literature.

PURPOSE: To evaluate the effect of age on the efficacy and safety of holmium laser enucleation of the prostate (HoLEP) for the treatment of symptomatic benign prostatic hyperplasia (BPH). METHODS: A total of 579 patients underwent HoLEP procedure performed by a single surgeon (SJO) between December 2009 and May 2013. The perioperative and functional outcomes of patients in the age groups of 50-59 (group A, n=44), 60-69 (group B, n=253), 70-79 (group C, n=244), and ≥80 years (group D, n=38) were compared. The Clavien-Dindo system was used to evaluate clinical outcomes. The International Prostate Symptom Score (IPSS), maximum urinary flow rate (Qmax), postvoid residual (PVR) urine volume, and urinary continence were used to assess functional outcomes. RESULTS: In this study, the patients ≥80 years had significantly higher presence of hypertension (P=0.007), total prostate volumes (P=0.024), transitional zone volume (P=0.002), American Society of Anesthesiologists scores (P=0.006), urinary retention (P=0.032), and anticoagulation use (P=0.008) at preoperative period. Moreover, the mean values of operation time, enucleation time, morcellation time, and enucleation weight were higher in group D compared with other group patients (P=0.002, P=0.010, P<0.01, and P=0.009, respectively). Patients aged ≥80 years had a longer hospital stay time (2.9±1.8 days) than other groups (group A, 2.3±0.7 days; group B, 2.3±0.7 days vs. group C, 2.4±0.7 days; P=0.001). All groups were similar in regard to the incidence of complications (Clavien-Dindo grade) post operatively (P>0.05). All the patients in the present study showed improvement in functional outcomes after HoLEP. By the sixth month, there were no significant differences in IPSS, quality of life, Qmax, and PVR among the groups (P>0.05). CONCLUSIONS: Compared with younger patients, the patients aged ≥80 years had a similar overall morbidity and 6-month functional outcomes of HoLEP. HoLEP is a safe and effective treatment for BPH among the elderly.

This study was performed to investigate histopathologically the effect of amniotic membrane graft (AMG)on haze in deep stromal wound of cornea. The excimer laser phototherapeutic keratectomy (PTK)was used to create the wound model of 150 micrometerdepth, 6.0 mmdiameter area in 72 white rabbitsbilaterally.Each eye was randomized to three groups: control (topical antibiotic alone), contact lens application and AMG. Corneal haze,the number of anterior stromal keratocytes and thickness of the regenerated stroma were evaluated after treatments in corneal wound, and also the morphological changes of anterior stroma connected with corneal haze were analyzed. The score of corneal haze in AMG group was significantly lower than those in the others at postoperative 3 days, 2, 4, 6 and 8 weeks. The anterior stromal keratocytes in AMG group significantly remained more than those in the others at postoperative 3 days. The number of keratocytes and thickness of regenerated stromal tissue in wound area of AMG group were statistically lower as compared with those of the other groups at postoperative 4 weeks. The architecture of stromal lamella was most reg-ular in AMG group. Transmission electron microscopic observation demonstrated that the cells in anterior stroma were the active fibroblastic cells with prominent rough endoplasmic reticulum at postoperative 8 weeks. These findings indicate that corneal haze is closely connected with proliferation of corneal stroma , suggesting that AMG on deep corneal stromal wound reduces corneal haze by preventing proliferation of abnormal collagen and fibroblasts at the anterior stroma of the wound area.
