Purpose: To investigate changes in eye movement amplitude after conjunctival recession and conjunctivo-limbal autograft for treating recurrent pterygium with ocular motility restriction. Methods: We retrospectively analyzed 18 eyes of 16 patients who had recurrent pterygium with ocular motility restriction, who had received conjuntivo-limbal autografts from January 2011 to December 2019 and who had been followed-up for more than 6 months. We evaluated changes in eye movement amplitude, best corrected visual acuity, uncorrected visual acuity, corneal astigmatism and keratometry, and recurrence and complication rates before and after surgery. Results: The mean age of the patients was 63.9 ± 9.7 years. Eye movement amplitude increased significantly from 5.80 ± 1.70 mm preoperatively to 7.02 ± 1.37 mm postoperatively (p < 0.001). The mean UCVA increased from 0.67 ± 0.46 preoperatively to 0.36 ± 0.35 postoperatively (p < 0.001). The mean corneal astigmatism decreased from 3.51 diopters (D) preoperatively to 1.22 D postoperatively (p = 0.001). According to the power vector analysis, M and B were significantly reduced after the surgery, but the changes in J0 and J45 were not significant. No recurrence of pterygium was observed. Conclusions Eye movement amplitude for severe recurrent pterygium with symblepharon or ocular motility restriction quantitatively measured the range of ocular movement clinically and was applied to determine the severity of recurrent pterygium and predict the surgical outcome. Conjunctivo-limbal autograft for severe recurrent pterygium is thought to be a safe and effective surgical method because it solves the ocular motility restriction caused by adhesions and has low recurrence rates, although it requires the skilled experience and techniques of the operator and a long operation time.

We experinced a case of 4p+ syndrome in male infant. He had multiple anomalies such as flat occiput, hypertelorism, low set malformed ear, lower anterior hair line, depressed nose, broad nasal bridge, bilateral complete cleft lip and palate, short neck, unusual position of fingers, ventricular septal defect and umblical hernia. He menifested growth and developmental retardation. Karyotype with banding revealed an extra short arm of chromosome 4. The mother's karyotype was normal. His father and father's sister had a translocation between the short arm of chromosome 4 and the short arm of chromosome 9; their karyotypes were 46, XY, t(4;9) and 46, XX, t(4;9), respectively. In this case, trisomy 4p was the result of parental balanced translocatiom. As this is the first case in Korea, it is worthwhile to report with reviewing literature.

PURPOSE: It has been reported that neovascularization of the optic disc (NVD) occurs in ocular ischemic syndrome, sickle cell hemoglobinopathy, ocular sarcoidosis, Eales' disease, and central retinal artery occlusion. However, NVD in acute ophthalmic artery occlusion had not been reported. Therefore, we report one unusual case of NVD in acute ophthalmic artery obstruction. METHODS: A 56 year-old man with complaint of abrupt decrease of visual acuity and periorbital discomfort underwent medical history taking, periorbital examination, fundus examination, and fluorescein angiography. He was followed up for 5 months RESULTS: Fundus examination showed segmentation of blood flow and diffuse retinal whitish opacity on the posterior pole around the center of the macula, without any cherry red spots in the perifoveal area. Fluorescein angiography showed a marked filling delay in the nasal retinal and choroidal circulations with a definite watershed zone involving the peripapillary choroid and macula. The retinal arteries filling and arteriovenous transit time were delayed. There was no light-perception vision and low intraocular pressure. Diabetes was found on systemic examination. Five weeks later, NVD and choroidal atrophy around the optic disc were detected. Panretinal photocoagulation was performed for the regression of NVD. NVD was regressed, but recurred.

BACKGROUND: To investigate how many rookie pitchers suffered from injuries while playing in the amateur league without guidelines for prevention of excessive pitching, we analyzed their amateur pitching patterns based on the pitch count, use of breaking balls, and pitches during winter camp. METHODS: Forty-one rookie pitchers who graduated from high school or university in 2013 and joined professional baseball teams. Participants were interviewed by a trainer using our questionnaire. Injury inclusion criteria were 1) history of shoulder surgery, 2) history of elbow surgery, 3) shoulder pain requiring treatment, and 4) elbow pain requiring treatment. RESULTS: Mean number of pitches per game and warm-up pitches for practice was 84.5 pitches (range, 15 to 130 pitches) and 16.4 pitches (range, 2 to 210 pitches), respectively. Mean number of pitches during the last year was 906.9 (range, 80 to 2,000). Mean number of maximal pitches was 127 pitches (range, 50 to 210 pitches). Fourteen pitchers had pitched over 150 pitches. Twenty-seven pitchers (65.9%) had pitched in spite of enduring pain. During winter training (mean 1.8 months), mean number of pitches per day was 162.5 pitches, and 20 pitchers (48.8%) had practiced pitching excessively despite the cold weather. Twenty-six rookies (63.4%) had shoulder pain or history of shoulder surgery, and 31 pitchers (75.6%) had elbow pain or history of elbow surgery. Only four participants (9.8%) did not have pain and history of surgery. CONCLUSIONS: For young baseball pitchers, guidelines for prevention of excessive pitching and for regulating the winter training program may be needed.

PURPOSE: This study was performed to evaluate the correlation between the change of the manifest refraction and change of the Orbscan-derived total refractive and axial power after laser in situ keratomileusis (LASIK). METHODS: A total of 34 consecutive eyes of 19 patients who were followed up for at least6 months after LASIK were included in study. The manifest refraction and Orbscan topography analysis of the 2, 3, 4, and 5 mm diameter zones of total refractive power and axial power maps were measured preoperatively and at least 6 month postoperatively. RESULTS: There were statistically significant correlations between all Orbscan-derived corneal power changes and changes of manifest refraction. Especially the total refractive power map in the central 4.0 mm zone gave the best statistically significant correlation with manifest refractive change (r2=0.790, p<0.01). CONCLUSIONS: These results indicate that the change of the manifest refraction in LASIK is best correlated with the change of the total refractive power map in the central 4.0 mm zone.

Fetal echocardiography is used by means of decleration of fetal cardiac anaztomy, to estabilish the diagnosis of congenital heart disease in utero. We attemped fetal echocardiography to ninty three pregnant women after intra uterine period 24 weeks, and estimated cardiac circumference, cardiac axis, pulmonary atery root diameter, arortic root diameter, diameter of inferior vena cava, diameter of superior ve studied how these estimates associate with following gestational na cava, and fractional shortening of ventricles. We ages. Cardiac axis was on the average 37.28 degree and cardiac apex was located in anterior left side of chest area. Aortic root diameter was 0.227 GA-0.043mm (GA=gestational age) at systolic phase, 0.203 GA+0.421mm at diastolic phase. Pulmonaly root diameter was 0.271 GA-0.029mm at systolic phase, 0.251 GA-0.067mm at diastolic phase. Thoracic aorta diameter was 0.195 GA+0.109mm at systolic phase, 0.198 GA+0.794mm at diastolic phase. Fractional shortening was 0.24 (1 Standard Deviation=0.11) in right ventricle, 0.23(1 SD=0.154) at left ventricle, and so ratio of right and left ventricle was 1.04(1 SD=0.51). Once normal fetal cardiac anatomy is understood, structural defects and/or alternation of function can be evaluated antenatally.
