Telangiectasia is characterized by permanently dilated small vessels usually arising from the suprapapillary plexus of venule capillaries, or arterioles. It may be etvlogically divided into the primary and secondary types. Rosacea, varicose vein, prolonged sun xvsure, radiation, and physical trauma may be the causes of secondary telangiectasia. We report herein a case of secondary telangiectasia associated which operation for a femur fracture.

Phthisis bulbi, resulting from repeated ocular inflammation and infection or ocular trauma, causes various degeneration of ocular tissue as well as changes in ocular external shape. It shows the impression of scleral thickening with calcification of ocular tissue and an unusual ossification as well. Having observed 31-year-old patients of phthisis bulbi and band keratopathy caused by repeated operation after ocular trauma years ago, we extracted the tan brown colored shell-like firm tissue in posterior segment and report sclerotic impression of some of ocular tissue and histopathologic finding of the typical ossificationof ocular tissue during the course evisceration.

4.The Effect of Retinoic Acid on Experimentally-Induced Proliferative Vitreoretinopathy in the Rabbit.
Journal of the Korean Ophthalmological Society 1997;38(10):1755-1763
The proliferative vitreoretinopathy was a complication followed by operation of rhegmatogenous retinal detachment. It was the mot, comon cause of a failure of retinal detachment surgery. It was characterized by the growth of cellular fibrous membrance in detached both retinal side and vitreous and also developed by giant retinal dialysis, posterior segmental trauma, excessive cryotherapy, endophthalmitis, retianl vascular disease. In order to prevent and treat of proliferative vitreoretinopathy, various methods of operation and drugs have been researched. We executed the experiment using the rabbit to observe the effect of retinoic acid that is known by inhibition of migration and proliferation of retinal pigment epithelial cell and fibroblast in vitro. With 121 eyes of rabbit, we induced the proliferative vitreoretinopathy by injecting of human retinal pigment epithelial cell, human fibroblast, and rabbit fibroblast into eyeball of rabbits. The extent of proliferative vitreoretinopathy was compaired by injecting those cells with the group that was injected by retinoic acid and control. The result was that in those cell groups, the extent of proliferative vitreoretinopathy was significantly higher in the rabbit fibroblast group than the other two groups(P<0.05). And in the groups that were injected retinoic acid, when subconjuctivaly injected(0.3mg/0.3ml), proliferative vitreoretinopathy was effectively suppressed and when intravitrealy injected (0.05mg/0.1ml), vitreoretinopathy was more increased than the control group. This result was probably caused by high concentration of retinoic acid in vitreous and further evaluation with various concentration of retinoic acid is needed. In conclusion, we recommend a rabbit fibroblast and subconjunctival injection of retinoic acid for the study on the suppressive effect of proliferative vitreoretinopathy.

BACKGROUND: Acne is a relatively common disorder, especially in the adolescent. The condition is characterizecl by comedones, papules and pusi:ules. Acne patients frequently wash their face. Cleansing with an effective agent is therapeutic and preventive for patients suffering from acne vulgaris. OBJECTIVE: The study was designed to compare thc efficacy and safety of a facial clemser consisting of 1% triclosan and 0.5% Ku Shen and a in in the treatment of facial acne vulgaris. METHODS: The study was camed out on two groups of people: a treatment and a control group. Efficacy and safety were assessed at baseline and at weeks 1, 2, 3, 4, 6, 8, 10 and 12. Efficacy was determined by investigating counts of non-inflamatory open and closed comedones, and inflamatory papules and pustules. Global improvement was also assessed. RESULTS: At week 12, the mean counts in the differe,nt lesions were as follows; 11.2 versus 17.2 for total lesions (p<0.05); 9.4 versus 11.3 for non-inflammatory lesions (p<0.05); 1.8 versus 5.9 for inflammatory lesions (p<0.05) in the treatment and control group, respectively. A Statistically significant difference was observed in patients overall self-assessment (p<0.05). The Group applying the facial cleanser with 1% triclosan and 0.5% Ku Shen felt significantly better than the one applying the control facial cleanser. Some patients developed mild and transient local side effects. CONCLUSION: Cleansing three times a day with a facial cleanser consisting of l% triclosan and 0.5% Ku Shen was found to be effective ancl safe for patients suffering from acne vulgaris.

Skin tags are very common skin tumors in middle age. In spite of their frequent occurrence, there was no reported cases of verruca vulgaris developing on the soft fibroma. We report a case of verruca vulgaris developing on the bag-like skin tag. We think that the incidence of HPV infection on the large skin tags may be higher than on normal skin due to their protrusion and repetitive irritation.

Secondary eyeball injury can be caused by head injury as well as direct injury of the eyeball or the orbit. Authors of this report have researched on 117 patients who were applied for ophthalmic examination which in care of the neurosurgical department and have researched frequency of secondary eyeball injury, association between the eyeball injury and the head injury, and favourable frequency of the eyeball injury which were developed without direct injury of the eyeball. There were 21 eyes(9.0%) with external ocular abnormality in 18 patients which included lagophthalmos, ptosis, paralytic strabismus, and there were 14 eyes(6.0 %) with posterior segment abnormality which were vitreoretinal hemorrhage, option. injury and papilledema in 11 patients. In association between the head injury and the eyeball injury, there were many external paralytic injury in basal skull injury and many posterior segment injury in cerebral parenchymal injury. After their injury, follow-up was executed in 3 month interval for 12 month. 15 eyes with external ocular abnormality and 8 eyes with posterior segment abnormality showed favourable progression. Posterior segment abnormality improved statistically significant at 3 month after injury(p<0.05). Secondary ophthalmic injury can be caused by various head injuries. Based on periodic observation, external ocular abnormality improved frequently at more than 9 months after injury. In cases of posterior segment abnormality, there was statistically significant improvement at 3 month after injury(p<0.05). Thus careful observation and treatment should be made in its early stage.

Nevus flammeus is a benign but cosmetically devascating congenital inalformation involving mature capillaries. The copper vapor laser is a therapeutic device which had been newly applied to this. Yellow copper vapor light is absorbed by the intraluminal oxyhemoglobulin mo ecules, leading to the destruction of blood vessels. This study was undertaken to evaluate the histobigic findings in a patient with nevus flammeus according to the sequential time after copper vapor laser therapy. The results were as followed, One hour after treatment, nonspecific damages to the epidermis and upper part of the dermis were observed. The specific damage to the vessels which showed thrombi formations and partial disruption of the vessel walls was prominent. One cay after treatment, degeneration of the epidermis and sepaiation of the dermoepidermal junction were apparent. Three days after treatment, extravasations of a small amount of erythrocytes and inflanimatory cell infiltrations were present, especially around the vessels. Seven days after treatment, the capillaries showed a deposition of fiorinoid material around themselves. Partial disappearance of the vessel walls was seen. There was hisi ologic evidence of the replacement of abnormal ectatic vessels by normal appearing vessels with small uminal diameters, surrounded by endothelial cells.
