Majority of the eyes with subfoveal neovascular membrane loss the central vision. We observed two patients who regained significant central vision as the result of the involution of subfoveal neovascularization. On follow-up fundus examination, the subretinal lesions revealed grayish neovascular membranes stained with fluorescein, but did not show the fluid leakage. And subretinal hemorrhage and subretinal fluid were gradually resolved. We assumed that functioning retinal pigment epithelium within the macula and young age were the important factors of the spontaneous improvement of visual outcome.

6.The Growth Hormone Levels and the Effect of Growth Hormone in the Children with Chronic Renal Failure.
Journal of Korean Society of Pediatric Endocrinology 1998;3(1):28-36
PURPOSE:Growth retardation is a serious clinical problem in children with chronic renal failure(CRF). Dialysis and renal transplantation do not provide an improvement in growth velocity. Possible causes of growth retardation are nutritional deficiency, electrolyte imbalance, uremia, renal asteodystrophy and chronic anemia. However, catch-up growth cannot be achieved after correcting these factors. There is no concordance about disturbances of growth hormone(GH)-insulin-like growth factor-I (IGF-I) axis. in CRF. This study was designed to evaluate the growth status, IGF-I, GH and the effect of GH in CRF. METHODS:Twelve children with CRF(five were treated conservative, seven were transplanted) were included. IGF-I, stimulated GH, 24 hour integrated concentration of GH (IC-GH)were measured. Six were given rhGH(0.1U/kg/day) for average one year. RESULTS: 1)Growth velocity(GV) was 3.2+/-0.8cm/yr(conservative therapy:3.3+/-0.7, transplanted:2.9+/-0.8). Height standard deveation score(SDS) was -2.4+/-1.3cm/yr(conservative therapy group:-3.3+/-1.4, transplanted group:-1.3+/-0.4). Bone age lagged 2.1+/-13yr behind chronological age. 2) IGF-I concentrations were normal. 3)Stimulated GH levels were normal(16.6+/-3.3ng/ml) except one patient. Twenty- four hour IC-GH were less than 3.2ng/ml in 4 patients. 4)After GH therapy, GV increased 3.3+/-0.7cm/yr to 5.4+/-0.8cm/yr and Ht SDS increased -3.3+/-1.4 to -2.9+/-1.5 in the conservatively treated group. GV increased 2.9+/-0.8cm/yr to 5.5+/-1.8cm/yr and Ht SDS increased -1.3+/-0.4 to -0.8+/-0.5 in the transplanted group. CONCLUSION: Stimulated GH was normal but spontaneous secretion of GH was decreased in some patients with CRF. This neurosecretory dysfunction may be one causative factor in CRF. For these patients GH replacement therapy will be effective in promoting growth.

Even though phototherapy is an effective means of treating hyperbilirubinemia, adequate binocular shields are essential to prevent light hazard of retina during phototherapy. The phototherapy to young albino rabbits was performed under various conditions; exposured for 12, 24, and 48 hours, continuity or intermittence of irradiation, and use of shields. Although there was no definite pathologic change in indirect ophthalmoscopic examination, severe damage was seen at electron microscopic level. In all experimental groups, swelling and edema of photoreceptor were seen. at right after phototherapy. Futhermore, more severe damage was seen in case of intermittent irradiated group and prolong exposed group. In mydriatic eyes, severity of damage was similiar to non mydi iatic eyes, but area of retinal damage was more extensive than non-mydriatic eves.. In control group which was protected by binocular shields during phototherapy, no significant abnormality was found.

Currarino triadis a unique malformation complex of congenital caudal anormalies, including anorectal malformatio (anal stenosis, anal ectopis, imperforated anus), sacral bony abnormality (scimitar or crescentic bony defect, malsegmentation) and presacral mass (meningocele, teratoma, enteric cyst or any combination of these). This triad is familial in at least half of cases and the usual symptomatology is constipation due to anorectal stenosis. The embryogenesis is presumably due to abnormal separation of the neuroectoderm from the endoderm, so this triad is in the spectrum of the split notochord syndrome. We report a case of Currarino triad in 5-month-old female patient who had chronic constipation and abdominal distention with brief review of the related literatures.
