Assessment of Scleral Contour Changes in High Myopia by Optical Coherence Tomography

Purpose@#This study aimed to establish and validate optical coherence tomography (OCT) based diagnostic criteria of high myopia. @*Methods@#This was a cross-sectional study including 100 eyes of high myopia with axial length larger than 26.5 mm and 100 control eyes, which were examined by spectral-domain OCT. Vertical and horizontal OCT of 9 mm scanning across fovea were analyzed. OCT characteristics including mirror artifact, scleral sink due to steep inclination of posterior sclera, scleral visibility, abnormality of outer retinal layer, foveoschisis, and dome-shaped macula were assessed in each group. @*Results@#The mean axial length was 28.65 ± 2.07 mm (range, 26.51–34.59 mm) in high myopia group and 23.79 ± 0.99 mm (range, 21.26–25.94 mm) in control group. Among the OCT characteristics noted at high frequency in the eyes with high myopia, three criteria achieving high sensitivity and specificity were determined: scleral sink over 500 μm, scleral visibility over 100 μm, and dome-shaped macula. Under conditions of presence of any of three criteria in either horizontal or vertical OCT scanning, the diagnostic sensitivity, specificity, positive predictive value, and negative predictive value for high myopia were found to be 95.0%, 98.0%, 98.0%, and 95.1%, respectively. In a new set of OCT images from 50 eyes with high myopia and 50 eyes of nonhigh myopia cases, the OCT-based criteria also proved similar level of diagnostic validity. @*Conclusions@#The OCT-based criteria, which directly addressed posterior scleral contour changes, may lead to an intuitive and accurate diagnosis of high myopia. Also, the criteria may contribute to early detection and monitoring of eyes that cannot be defined as high myopia but can progress. OCT may be useful for monitoring high myopia patients as OCT can detect myopia-associated retinal pathologies as well as scleral contour changes.

Novel Adjuvant Method to Assist Localisation of a Cyclodialysis Cleft

PURPOSE: To introduce a novel adjuvant technique to locate cyclodialysis cleft using a laser pointer in a gonioscopic view. CASE SUMMARY: A 36-year-old man complaining of blurred vision in his left eye after blunt trauma 2 weeks prior was referred to our hospital. Gonioscopy showed a cyclodialysis cleft from 3 to 4 o'clock and fundus revealed hypotonic maculopathy. After the failure of medical treatment, we tried various interventions such as injection of viscoelastic agent into the anterior chamber and intravitreal gas tamponade with transconjunctival cryotherapy. Since those were not successful, we decided to treat the patient with direct cyclopexy. For the preoperative localization of the cleft, we tried a new technique that uses a laser pointer. On gonioscopic examination, an assistant shot the laser toward the limbal area where the suspicious cleft was located. We were able to precisely locate the cyclodialysis cleft if the laser pointer light was seen through the cleft in the gonioscopic view. With the aid of a laser a pointer, the cleft was successfully closed. CONCLUSIONS: Localization with a laser pointer is simple, safe, rapid, and helpful for planning surgical repair of a cyclodialysis cleft without expensive equipment.

Comparison of Patient Characteristics in Thyroid-Associated Ophthalmopathy with and without Strabismus

PURPOSE: To determine immunochemical and clinical differences in thyroid-associated ophthalmopathy (TAO) patients with restrictive strabismus and without strabismus. METHODS: A retrospective chart review of 15 TAO patients with strabismus (25 eyes) and 24 TAO patients without strabismus (39 eyes) who presented to the Ophthalmology Clinic between August 2011 and December 2013 was performed. Visual acuity, intraocular pressure (IOP), Hertel exophthalmometry, soft tissue score, and enlargement of extraocular muscles on computed tomography (CT) were obtained and compared in each group. Thyroid related autoantibody (thyroid-stimulating hormone receptor antibody, TRAb; thyroid peroxidase antibody, TPOAb; anti-thyroglobulin antibody, TgAb) titers and positive rates were obtained at the time of diagnosis or before treatment and analyzed. RESULTS: The gender and smoking proportion were not significantly different between the 2 groups. The mean age of TAO patients with strabismus was 52.53 years and of TAO patients without strabismus 40.33 years (p = 0.004). The differences in visual acuity and IOP between the 2 groups were not significant. Hertel exophthalmometry showed less proptotis in the TAO with strabismus group than the TAO without strabismus group (16.84 mm versus 18.67 mm). The soft tissue score was not significantly different. The extraocular muscle enlargement rate of TAO with strabismus was significantly higher than in TAO without strabismus group. In the TAO with strabismus group, TRAb level was higher than in the TAO without strabismus group (p = 0.021). CONCLUSIONS: The TAO with strabismus group was older and had higher positive rate, level of TRAb, and extraocular muscle enlargement rate on CT than the TAO without strabismus group. Furthermore, proptosis was less definite in the TAO with strabismus group.

A Case of Intratarsal Keratinous Cyst of the Meibomian Gland

PURPOSE: To report a patient presenting with an intratarsal keratinous cyst of the Meibomian gland in the upper eyelid and a review of the relevant literature. CASE SUMMARY: A 65-year-old male presented with a right upper eyelid mass which started 5 months prior. The patient reported that the mass recurred several weeks prior even after incision and curettage procedure. The mass was 9 x 5 mm in size and located in the center of the right upper eyelid at the level of lid crease, fixed to the tarsus and a whitish elevated focus was observed at the palpebral conjunctival surface. The mass was excised under local anesthesia and originated from the tarsus. The histopathological examinations revealed an intratarsal keratinous cyst composed of stratified squamous epithelium without keratohyalin granules and filled with keratin. The immunohistochemical studies showed positive staining results for cytokeratin 5/6, epithelial membrane antigen, and carcinoembryonic antigen. CONCLUSIONS: Intratarsal keratinous cyst of the Meibomian gland should be considered as a differential diagnosis of a recurrent tarsal mass.

The 2 Cases of the Sacrospinous Ligament Fixation for the Massive Eversions of the Vagina after Total Abdominal Hysterectomy / 대한산부인과학회잡지

Massive eversion of the vagina is one of the most disturbing disorders confronting a woman. It is a complex disorder that always surgical, and all defects. The managements is always surgical, and all defects must be repaired concomitantly. Current surgical practice relies primarily on the strength of the endopelvic fascia and certain ligaments. Massive eversion of the vagina can be treated by a variety of transvaginal and transamdominal surgical technique. In most instances a transvaginal approach is useful. If strong cadinal and uteroscral support in not available fiocation of the vginal vault to the sacrospinous ligment is useful. In 1987, Miyazaki introduced his Miya Hook ligature carrier. With this instrume nt, introduction of the needle became safer and easier than with the Deschamp aneurysm needle. We had experienced two cases of massive eversion of vagina after the total abdominl hyst erectomy who were treated succesfully with sacrospinous ligement fixation by using Miya Hook. We report above two cases and review briefly.

A Clinical Study of Ifosfamide/Mesna and Cisplatin in Recurrent Epithelial Ovarian Cancer / 대한산부인과학회잡지

This study was planned to evaluate the efficacy and toxicity of fosfamide/mesna plus cisplatin combined regimen in patients with recurrent and initial therapy-resistant epithelial ovarian cancer. Controversy still remains over the efficacy of cisplatin containing combined chemotherapy as the treatment of recurrent ovarian cancer and refractory to first line chemotherapy. Ifosfamide(isophosphamide) is an analog of cyclophosphamide. It has shown evidences of activity in ovarian cancer and lack of cross-resistance with cyclophosphamide. This study was undertaken for the clinical analysis and evaluation on 16 patients, who were admitted and treated with advanced or recurrent ovarian cancer at the Sooncheunhyang University Chunan Hospital from January 1994 to July 1996. The results were as follows: 1. The mean age of patients was 62 year old with range from 44 to 72. 2. The most frequent side effect was nausea and vomiting(75%), followed by leukocytopenia(68%), alopecia(44%), nephrotoxicity(37%), neurotoxicity(25%), and hepatotoxicity(12%). 3. The mean survival period was 24 months in clinical response cases ranged from 11 months to 36 months, 5 months in progressive cases ranged from 1 month to 14 months. 4. In clinical stages, stage II was 6 cases(37.5%), III was 6 cases(37.5%) and IV was 4 cases(25%). 5. Previously all patients were received debulking surgery and PAC hemotherapy. 6. Overall respons rate was 44%(7/16).
