2.Electroretinogram in Experimental Ocular Siderosis.
Journal of the Korean Ophthalmological Society 1968;9(2):7-12
Experimental ocular siderosis was induced in fourteen albino rabbits by the insertion of iron fragments through the scleral incision made at equatorial region. ERGs were recorded up to 30 days after the insertion of iron, both in scotopic and photopic conditions. Light stimulus used was electronic photoflash of 2 msec duration. The changes in the scotopic b-wave were classified into 3 types. The first type (4 eyes) showed gradual decrease finally attaining 54.6% of the original amplitude. The second type (3 eyes) showed supernormal b-wave during whole period of study, the increase reached 43.0% after 30 days. In the third type (6 eyes) the b-potential remained almost stationary. The scotopic a-wave changed in a similar way as the b-wave. Sometimes negative (-) type ERGs were recorded, especially during the falling stage of the b-potential. The photopic a- and b-waves changed almost parallel to the scotopic components. By slitlamp biomicroscopy and ophthalmoscopy, fibrous connective tissue proliferated around the iron fragments, never extending deep into the vitreous body. Fundi were well visible except the insertion site. Histological section revealed moderate scar tissue formation around the insertion site of iron, and mild visual cell and ganglion cell destructions.

3.Experimental Studies on Vitreous Implantation.
Journal of the Korean Ophthalmological Society 1970;11(1):1-5
Effects of implantation of fresh and stored vitreous were studied on albino rabbits. Auto-and bomo- implantations of fresh vitreous were performed in sixty eyes, and course was followed up to one month after implantation operation. Of these, thirteen eyes were discarded because of bleeding into vitreous cavities and contamination of vitreous by blood. In remaining forty-seven eyes, vitreous became clear after ten days. Intraocular pressure which had been low daring the first few days, normalized within this period of time. No complication was observed. Implantation of homologous vitreous which had been stored in frozen state for one to three months, resulted in clear vitreous in eight out of ten eyes operated. Bleeding and blood contamination occurred in two eyes. From the results, it can be concluded that vitreous implantation is relatively safe and effective procedure.

A case of bilateral absence of vas deference with sterility is reported. By new 15O cases of congenital absence of the vas deference, rather a rare congenital anomaly, were reported.

Vitreous hemorrhages of white rabbit eyes were obtained by the following three methods and their ultrasonographies were checked several times for four weeks. 1 st group: fresh human blood was injected into the vitreous cavity through the sclera, 2 nd group: oxalated human blood was injected into the vitreous cavity in the same way, 3 rd group: a 26 gauge needle was inserted into the vitreous cavity and retinal vessels were mechanically ruptured to cause vitreous hemorrhage. Ultrasonography of the above groups revealed no definite differences between groups, but a high echo from the vitreous hemorrhages in initial stage changed to several low echoes in later stage. This fact was well matched with funduscopic observation for gradual absorption of the vitreous hemorrhage.

9.Experimental Vitreous Hemorrhage.
Journal of the Korean Ophthalmological Society 1977;18(4):323-326
Experimental vitreous hemorrhage was induced in rabbit eye by rupturing the choroidal vessels mechanically with a 26 gauge needle introduced into the eye through the supero-nasal quadrant of the sclera, 10mm posterior to the limbus. Absorption of vitreous hemorrhage was evaluated by indirect ophthalmoscopy in the following groups and pathological specimens were obtained three months after vitreous hemorrhage. Group I: after vitreous hemorrhage, no additional management was done for control(4 eyes). Group II: vitreous gel was disrupted mechanically with 26 gauge needle to liquefy the vitreous(4 eyes). Group III: 1cc of vitreous waS replaced with the same amount of normal saline prior to vitreous hemorrhage (4 eyes). Group IV: 0.3cc of hyaluronidase (75 units) was injected into the posterior vitreous prior to vitreous hemorrhage (4 eyes). In groups I, II, and IV, vitreous hemorrhages were completely absorbed in 8 to 10 weeks. whereas absorption time was shortened in group m to 6 to 8 weeks. Pathological specimen revealed no infiltrations of inflammatory cells, but only glial proliferations.
