RESUMO
Purpose@#To report a case of bilateral calcific band keratopathy treated with dipotassium edetic acid (EDTA) in a blood collection tube, an approach that has not been used previously in the Republic of Korea.Case summary: A 77-year-old male patient, with a history of diabetes and hypertension, presented with decreased vision in both eyes that had begun 1 year prior. Five years prior, the patient had undergone cataract surgery in the right eye and had received a diagnosis of prostate cancer for which he was currently under observation without surgical treatment. At the initial eye examination, his best-corrected visual acuity was 0.15 in the right eye and 0.1 in the left eye. Calcium deposition was observed in the center of the cornea by slit-lamp examination, resulting in a diagnosis of band keratopathy. We proceeded to dissolve the dipotassium EDTA coated on a blood collection tube with distilled water. Using the dissolved dipotassium EDTA, we peeled off the corneal epithelium under local anesthesia to remove the calcium deposition. One week after surgery, the visual acuity of both eyes improved to 0.6, and no recurrence or complications occurred for 7 months. @*Conclusions@#As a new treatment for band keratopathy, we discovered that dipotassium EDTA is more convenient to obtain than the conventional disodium EDTA. We expect that dipotassium EDTA will be widely used in the treatment of band keratopathy.

RESUMO
Purpose@#The purpose of this study is to evaluate the change in eyebrow position and three parts of brow according to frontalis muscle (FM) function after upper lid blepharoplasty. @*Methods@#We subdivided 45 patients who had undergone upper eyelid blepharoplasty into three groups according to FM function: Group 1 (Poor, <4 mm), Group 2 (Good, ≥4 mm and <8 mm), and Group 3 (Excellent, ≥8 mm). Photographs of patients were taken before and three months after surgery. We analyzed brow descent and brow-to-pupil (BPD), brow-to-medial canthus distance (BMCD), brow-to-lateral canthus distance (BLCD) of each group. @*Results@#Mean FM function was measured as follows: Group 1 (2.11 ± 0.94 mm), Group 2 (6.2 ± 1.24 mm), Group 3 (10.25 ± 1.25 mm). There was no significant difference in the degree of eyebrow height change between Group 2 and 3, but Group 1 showed significant eyebrow height descent compared Group 2 and 3 (p < 0.05). In all three groups, the lateral brow position was significantly lowered compared to middle or medial brow position after blepharoplasty (p < 0.04). After blepharoplasty, 3 eyebrow ptosis occurred in Group 1, not in Group 2 and 3. @*Conclusions@#Patients with poor FM function less than 4 mm (Group 1) and BLCD of all group showed significant eyebrow descent after blepharoplasty. Since the weaker FM function and FM connection with eyebrow, the more lowered eyebrow after blepharoplasty, the evaluation of FM function may help predict the lowering of eyebrow height after blepharoplasty and decide whether to perform brow lift at the same time.
RESUMO
PURPOSE: A case of bilateral lacrimal caruncle steatocystoma simplex and sebaceous gland hyperplasia, which rarely occurs in the periocular area, is reported. CASE SUMMARY: A 42-year-old female presented with a bilateral caruncular mass, which had been growing for a few months. A physical examination revealed soft, non-tender, rounded masses and no other ophthalmic findings. Under local anesthesia, the masses were completely excised. In the histopathological examination, a cystic mass containing a sebaceous gland in the stratified squamous epithelium cyst wall was found. A hyperplastic sebaceous gland and a dilated sebaceous gland duct were also found. Steatocystoma simplex and sebaceous gland hyperplasia, respectively, were diagnosed. There was no recurrence or complication after excision. CONCLUSIONS: Steatocystoma simplex and sebaceous gland hyperplasia are benign tumors that rarely occur in the lacrimal caruncle. They can be diagnosed and treated by complete excision. Steatocystoma simplex and sebaceous gland hyperplasia should therefore be considered as differential diagnoses of a lacrimal caruncle mass.
