PURPOSE: To evaluate the relationship between foveal thickness and axial length and refractive power in healthy Koreans. METHODS: Ninety-eight healthy eyes were studied. The axial length was measured using A-scan (Paradigm mode p45, Kent, U.K.) and refractive power using automatic refractor Automatic refractor(HARK-599, Carl Zeiss, USA). The subjects were divided into 2 groups based on axial length (>or=25 mm and <25 mm) and refractive power (-6.0D). The foveal thickness was measured using OCT 3000 (Optical Coherence Tomography, Carl Zeiss, USA) and the statistical relationship between the 2 groups was analyzed by independent t-test. RESULTS: There was no statistically significant difference found in foveal thickness according to axial length between the two groups (p>0.05) nor according to refractive power (p>0.05). CONCLUSIONS: When eyes with pathologic myopia were excluded, The axial length and refractive power of the eyes had no relation to foveal thickness measured by OCT.
Myopia

Stickler syndrome is an autosomal dominant disorder of connective tissue with a wide range of expressivity and incomplete penetrance which is called hereditary progressive arthro-ophthalmopathy. Affected neohates may present with the Pierre-Robin syndrome, progressive myopia, retinal detachment, flat face, hypertelorism, progressive arthritis. Early recognition of the syndrome is important, not only for genetic counselling but also to offer a more precise prognosis and proper treatment of many serious disorders that may occur in affected children. We experienced a case of Stickler syndrome with large eyeballs in a 3-day-old female baby who showed Pierre-Robin anomaly, flat face, hypertelorism, epicanthal folds, long philtrum, micrognathia, deft palate, high congenital myopia, chorioretinal degeneration, thin habitus and hyperextensible joints.

High myopia, often called malignant, pathologic or degenerative myopia, involves a progressive elongation of globe, accompanied by degenerative changes of the retina and choroid. Continued stretching and degeneration of the choroid causes eyes with severe myopia to develop breaks in Bruch's membrane which, called lacquer cracks, and permits neovascular proliferation from the choriocapillaris into the subretinal pigment epithelial space. Neovascularization associated with severe myopia deteriorates central visual acuity due to exudation and/or hemorrhage. Laser photocoagulation therapy is useful in treating neovascular membrane outside the foveal avascular zone or extending to the edge of the perifoveal capillary network. We have evaluated three patients with macular hemorrhage which associated with high myopic choroidal degeneration. Subretinal neovascular membrane was detected by fluorecein angiography and was treated with monochromatic Argon green laser photocoagulation in two patients indicated. The visual acuities were improved. But one patient who had macular hemorrhage involving both foveas could not be treated with laser photocoagulation. Then his visual acuity severly decreased. We give our experiences with the review of other papers in this report.

PURPOSE: To evaluate visual acuity changes over 3 years following surgical reattachment of macular hole retinal detachment (MHRD) developed in high myopia.METHODS: A retrospective analysis was performed using the medical records of patients with highly myopic eyes who underwent pars plana vitrectomy with internal limiting membrane peeling or the internal limiting membrane flap technique for MHRD. Changes in best-corrected visual acuity (BCVA) were measured at baseline, 6 months, 1 year, 2 years, and 3 years.RESULTS: Of the 22 eyes analyzed, macular hole was closed in 13 and unclosed in nine. BCVA significantly improved from 1.61 ± 0.39 logarithm of the minimum angle of resolution (logMAR) at baseline to 1.17 ± 0.43 logMAR at 6 months and 1.33 ± 0.48 logMAR at 2 years after MHRD surgery. At 3 years, BCVA significantly decreased compared with that at 6 months, and visual improvement from baseline was not significant. BCVA and proportion of vision loss ≥0.3 logMAR were not different between the closed and unclosed macular hole groups.CONCLUSIONS: Visual improvement after surgical reattachment of MHRD in high myopia was not maintained, and favorable macular hole closure effects were not observed at 3-year follow-up.

To investigate general misconception on the eye problems, we have reported the misconception of students of middle school, high school and college for the first report. For its etiological study, we studied the false descriptions on the eye problems in the textbooks of primary school, middle school and high school. We found the false descriptions in terminology, causes of the myopia, contact lens and conjunctivitis(Trachoma). The result suggests that the main causes of misconception on the eye problems of students are the false descriptions on the textbooks of primary school, middle school and high school.

A survey on the myopia in 579 pupils of 2 primary schools o Tan Mai and Van Noi in Ha Noi was carried out. Results showed that: light intensity was at the hygienic standard, but in some sitting places the ligh intensity was too high. The height of the desks were not compatible with the height of the pupils. The poor vision was 17%, the refraction problem was 24%, hypermetropic myopic astigmatism were 11%, some influence factors to vision disorder of the pupils were found out initially. The vision disorder of the pupils at Tan Mai school was significant higher than this in Van Noi school.

Studies on 5,050 pupils at 3 levels of primary education in Ha Noi, Nam Dinh and Thai Nguyen during 1999-2001 showed that: the myopia of pupils had increased by the learning grade. The myopia rate of pupils in urban areas is higher than that in suburb areas. Some factors were related closely to the rate of myopia including the lighting level inside classes, the dimensions of tables and desks, the sitting position of pupils in classes

To investigate general misconception on the eye problems, we have reported the misconception of students of middle school, high school and college for the first report and the false descriptions on the eye problems in the textbooks of primary school, middle school and high school. As the third report, we have investigated the errors on the ophthalmic problems which were found on the health related books sold on the bookstore. We found the errors in 27 books among about 50 books. The errors about the myopia were the most prevalent(in 10 books) among them.

Objective: This small case series demonstrated pars plana vitrectomy and silicone tamponade without internal limiting membrane (ILM) peeling to be a simple, safe, and effective surgical technique for the treatment of myopic traction maculopathy (MTM). Methods: This is a small case series consisting of 3 eyes with MTM. In all eyes, pars plana vitrectomy with silicone oil tamponade was performed by a single vitreoretinal surgeon. Functional and anatomic outcomes are reported. Results: All 3 eyes had improved visual acuity with no noted short-term complications such as iatrogenic macular hole and retinal detachment. Although foveoschisis was only partly anatomically resolved in 2 out of the 3 cases, functional outcome, in terms of visual acuity at last visit, was satisfactory. Conclusion Vitrectomy with silicone oil tamponade without ILM peeling is a simple, effective, and safe optional surgical technique to treat MTM.
