A middle-aged gentleman with history of left penetrating keratoplatsy presented with left eye perforated corneal graft secondary to infective keratitis. The affected eye was blind from absolute steroid-induced glaucoma. In view of expected poor graft survival in a blind eye, globe removal was offered. However, the patient refused the treatment and request for another corneal graft. This case highlights both the possibility of good outcome of cornea graft in such a case, and also illustrates that patient’s autonomy to refuse treatment option outweighs beneficence.

PURPOSE: To report on the classification of congenital stationary night blindness (CSNB) and multifocal ERG findings. METHODS: We studied three patients (case 1-3) with night blindness but normal fundus and one patient (case 4) with decreased vision after trauma with respect to the patients' medical history, familial history, refraction, slit lamp examination, fundus examination, FAG, ERG, and multifocal ERG. RESULTS: The ERG in case 1 showed a decreased rod response, and this patient was diagnosed with Riggs-type CSNB. The typical "negative ERG" was found in all three cases of ERG (except case 1), and these cases were diagnosed with Schubert-Bornschein-type CSNB. Based on Miyake's classification, case 2 was incomplete, and cases 3 and 4 were complete. The mfERG of the cases with complete Schubert-Bornschein type had delayed implicit times of the first-order kernel and decreased amplitudes of the second-order kernel. The delayed implicit times and the decreased amplitudes of the first- and second-order kernels were found in the cases of Riggs- type and incomplete Schubert-Bornschein-type.

The congenital cataract is the relatively common cause of the blindness in childhood, and its etiology is multiple but most of etiology is unknown. The inheritance is the largest single category of cause of congenital cataract. The modes of the inheritance are autosomal dominant, autosomal recessive and X-linked. The autosomal dominant inheritance is the most common type. We experienced hereditary congenital cataract, which transmitted with autosomal dominant inheritance. So we reported this patients with review of literatures.

An analysis of four patients with congenital stationary night blindness showed that all had essentially normal fundi. We studied electro physiologic examinations including electroretinogram(ERG), electrooculogram(EOG) and pattern visual evoked potential(VEP). We classified these patients into two groups, one case as Schubert-Bornschein type and three cases as Riggs type based on the evaluation of scotopic and single bright flash ERG. The oscillatory potentials were absent in one case of Schubert-Bornschein type and reduced in two cases of Riggs type. The hereditary mode of three patients in one family was autosomal dominant.

With the support of the World Vision, in June 2004, the district Chi Linh Health Centre (Hai Duong province) co-operated with Institute of Ophthalmology to survey on blindness and some eye diseases in 3,370 people. Objectives: identify the situation of blindness and some eye diseases in Chi Linh in the year 2004; identify the trachoma prevalence after 4 years implementing the project of trachoma control in Chi Linh. Methods: cross sectional study; Target population: all people. Results of survey has shown the prevalences of blindness and some eye diseases are so high compared with the figures of country survey, the leading causes of blindness are cataract, glaucoma, corneal opacity and pterigium. Conclusion: Thank to project of trachoma control supported by WV conducted in Chi Linh from 1999, the prevalence of active trachoma now has dropped to level under the criteria of WHO on active trachoma elimination. However, the rate of trichiasis is very far from criteria of WHO. Results of survey has shown also the serious situation of blindness. That is the big challenge for health workers and ophthalmologists in Hai Duong province and Chi Linh district in order to reduce the blindness prevalence in the next years.

Blindness prevalence and its causes are necessary for planning of the Blindness Prevention activities. Objectives: to evaluate blindness prevalence and causes, the output and outcome of cataract surgical services in the community. Methods: Cross-sectional prescriptive study was conducted on 1,729 persons of 50 years old and over. Results: Bilateral blindness prevalence is 3.41%, monocular blindness prevalence is 7.63% in the group of 50 years old and over. Main causes of blindness are cataract (47.5%), pathology of posterior segment (22.0%), glaucoma (16.9%), trachoma (3.4%). Bilateral and monocular cataract-related blindness rates are 1.50% and 3.76%, respectively. Prevalence of TT in one eye is 4.22%, in both eyes is 2.66%, prevalence of Pterigyum in one eye is 19.56% and in both eyes is 7.99%. The bilateral aphakia rate is 1.39%, monocular aphakia rate is 2.37%. The cataract surgical coverages are 63.89% of patients and 43.20% of eyes. The successful surgical rate is 67.42%. Main barriers for cataract management service are poverty (23.1%), unawareness (18.2%), and no accompaniers (9.1%). Conclusions: Main cause of blindness in Hanam is still cataract. The CSSR is good but the successful surgical rate is not high. In the next 10 years promotion of cataract surgery output and surgical quality should be done in order to reduce blindness prevalence.

Purposes of the prevention of blindness are considered in manifold. In view of the increasing number of the blind in this community, activities for the prevention of blindness would be placed on the higher position in health problem. Modern concepts of application of prevention in ophthalmology are introduced and the importance of preventive research in ophthalmology is emphasized. A plan of organization for the prevention of blindness (to-be) in Korea under the auspices of the Korean Ophthalmological Society is suggested.
