We experienced a case of arteriovenous hemangioma showing Dariers sign on the forehead of a 43-year-old man. He presented with a single, 1 * 1.5cm sized, violaceous, asymptomatic nodule with a history of an intermittent wheal at the lesional site. This skin lesion showed Dariers sign clinically and proliferation of mast cells histopathologically with the punch biopsy specirnen suggesting urticaria pig- mentosa. Howerer, we could diagnose it as a arteriovenous hemangioma on complete excision, as the specimen showed arteriovenous proliferation with increased mast cells in a perivascular pattern. This case showed confusing clinical signs and showed the importance of complete excision for the diagnosis of a small skin tumor especially when a vascular proliferating tumor is suspected.

Trichoadenoma is a rare cutaneous tumor that was first described by Nikolowski in 1958. It usually occurs as a single tumor on the face and its size varies from 3 to 50mm in diameter. It may arise any time during adult life. This tumor is less mature than trichofolliculoma and more differentiated than trichoepithelioma, and it is considered as a benign tumor with differentiation toward the infundibular portion of the pilosebaceous canal. In this report, we describe a 61-year-old women who developed trichoadenoma on the left shoulder of 3 years duration. The lesion was asymptomatic and had grown slowly. Histopathological findings showed numurous horn cysts with central keratinous material and solid tumor islands reaching to the deep dermis. Immunohistochemical studies showed negative findings for eccrine differentiation.

Keratoconus (conical cornea) is a condition, beginning about puberty and developing mainly in females, in which the apex of the cornea thins gradually and usually bilaterally. The etiology is unknown. The presenting symptom is a reduction of the patient's vision owing to the development of a high degree of irregular myopic astigmatism. Early in the course of the disease the cornea does not look conical. The diagnosis of Keratoconus is confirmed by the distorted reflex observed with a Placido's disc and abnormal keratometer readings. In more advanced stages, signs include the obvious cone-shaped cornea and indentation of the lower lid by the cornea. By slit lamp biomicroscopy, vertical lines are noted in the deep layers of the stroma: the corneal nerve fibers are increasingly visible; and in about 50% of cases a yellow or green line is present around the base of the corn (Fleischer's ring). In advanced cases Bowman's membrane and Descemet's membrane rupture. Microscopically there is thinning of the tissue spaces between the corneal lamellae, fragmentation of the basement membrane of the comeal epithelium, fibrillation of Bowman's membrane, and folds or ruptures in Descemet's membrane. Acute hydrops may occur when Descemet's membrane ruptures. This is characterized by sudden cloudiness of vision due to imbibition of aqueous in the corneal stroma. However, as Descemet's membrane regenerates, the edema subsides. Permanent scarring may result if Bowman's membrane ruptures. Acute hydrops of the cornea was developed respectively in left eye on Oct, 1976 and in right eye on Dec, 1976 in a 13 year old Korean girl with Keratoconus O.U.

Purpose: To investigate the influence of intraocular pressure (IOP)-lowering eye drops on myopic retinoschisis. Methods: We investigated myopic retinoschisis patients with high myopia (defined as a myopic refractive error more than -8.0 dioptersor an axial length longer than 26.5 mm), who were suspected of having glaucomatous optic neuropathy, using IOP-loweringeye drops between April 2014 and December 2018. We retrospectively analyzed the changes in optical coherence tomographyfindings after 6 months using IOP-lowering eye drops. The progression of retinoschisis was assessed by analyzing retinalvolume changes. A decrease in the total retina volume and a decrease in volume more than 10% in one section out of five withoutmore than a 10% volume increase in any other section was defined as resolution of myopic retinoschisis. The opposite casewas defined as an aggravation. Results: We analyzed 17 eyes of 15 patients with high myopia. Six of 17 eyes (35.3%) showed a resolution of myopic retinoschisisat 6 months after using IOP-lowering eye drops. Of the 17 eyes, two (11.8%) experienced progression of myopicretinoschisis. Seven out of 14 eyes (50.0%) who were followed-up over 1 year showed resolution of myopic retinoschisis, andtwo eyes (14.3%) experienced progression of myopic retinoschisis. There was no macular hole development or posterior vitreousdetachment during the follow-up period in the seven eyes, and there was no significant correlation between the absolute valueof the initial IOP, axial length, IOP change, and degree of improvement of myopic retinoschisis. Conclusions The use of IOP-lowering eye drops on highly myopic eyes with retinoschisis showed a significant improvement ofmyopic retinoschisis, when compared to previous studies. These findings suggest the possibility of IOP-lowering eye drops delayingor improving the natural course of myopic retinoschisis.

Purpose: To evaluate the short-term ophthalmic side effects of bilateral same-day intravitreal bevacizumab injections. Methods: We retrospectively analyzed patients who underwent intravitreal bevacizumab injection in both eyes on the same day from January 2015 to June 2019. The patients were followed up at 1 day, 1 week, and 1 month after the injection. Results: A total of 281 patients (153 males and 128 females) and 562 eyes were included in the study, and 950 bilateral same-day intravitreal bevacizumab injections were performed. The mean age of patients was 58.87 ± 13.44 years. The most common cause of bilateral injection was that of complications due to diabetic retinopathy, which accounted for 66.3%, followed by age-related macular degeneration at 22.2%, retinal vein occlusion at 5.1%, and central serious chorioretinopathy at 2.1%. There were 0 cases of endophthalmitis after 950 injections, 13 cases of subconjunctival hemorrhage, and 17 patients with a temporary elevation of intraocular pressure. There were 11 patients with acute intraocular inflammation after bilateral injection, but none in both eyes. Patients with acute intraocular inflammation were followed up at short-term intervals until they improved. All patients showed complete improvement within 2 weeks after injection. Comparing the patients’ condition before and after injection, visual acuity improved (p < 0.001). Conclusions In terms of the frequency of short-term ophthalmic adverse events, bilateral same-day intravitreal bevacizumab injection is a safe procedure with fewer side effects and is more convenient for both the patient and the doctor.
