Fluorographic Findings of Normal Optic Disc

One hundred normal optic discs were analysed by fluorographic fundus pictures. Horizontal diameter of optic disc was set as 10. The following results were obtained. 1) The vertical diameter of optic disc was larger than the horizontal one. (10.77 : 10). 2) The ratio of diameters of cenitral retinal vein(CRV) was 1 : 1.51 before and 1 : 1.47 after fluorescein injection. 3) The central retinal artery(CRA) located nasal to the CRV in most cases. 4) In nearly half of cases, physiologic cups located at the nasal portion of optic discs. 5) The average size of physologic cup was 2.90. 6) The cilioretinal artery was detected in 58% of cases in which one cilioretinal artery was found in 42%, two was found in 16%. 7) The CRA made branchings more than retinal veins (7.74 : 5.48) and total sum of diameters of retinal artery was larger than that of retinal vein at the disc margin.

Fluorescein Angiographic Studies on the Central Serous Chorioretinopathy

Fluorescein fundus angiography is a valuable method in diagnosis and treatment of central serous chorioretinopathy. We observed 136 eyes of central serous corioretinopathy by fluorescein fundus angiography, between March, 1973 and September, 1974. Leakings are analysed by pictures and the following results were obtained. 1. The cases were classified by leaking patterns as following: Type I, leaking is unremarkable, Type II, leaking point appears at early arterial phase and fades out gradually. Type III. leaking point appears at early arterial phase and increases in density gradually, but the size of the leaking area is not enlarged. Type IVa, leaking point appears at early arterial phase and increases concentrically in the density and size. Type IVb. leaking point appears at early arterial phase and increases vertically (mushroom shape) in its size and density. 2. In large serous detachment of the macula, the leaking tend to be single and located at peripheral area. 3. In type IVa and IVb, the leaking tend to be located superiorly and nasally in midperiphery. 4. Photocoagulation can be applied more easily in type IVa and IVb for the location of the leaking points.

One Case of Intra-Orbital Hemangio-endothelioma

Here, we report one case of intra-orbital hemangio-endothelioma. The patient was a Korean male aged 37. The most outstanding complaint was exophthalmos of the left eye. His left eye began to protrude insidiously without pain since 4 years ago. A soft movable mass was palpated on the medial portion of the upper orbital margin and the ocular motility was limited to upward, but ocular deviation was not present. Pathologic diagnosis was intra-orbital hemangio-endothelioma, sclerotic, borderline malignancy. This tumor was well encapsulated and any evidence of involving bone and soft tissue was not found. The size of was 2cm X 2.5cm X 3.5cm. Extirpation was performed by means of superior orbital approach. Tumor mass was removed entirely with finger dissection. The vision was not changed but the cosmetic result was satisfactory.

The Effect of Mydriatics and Miotics Using Soft Contact Lenses

The therapeutic applications of Soft Contact Lenses including its optical use are most popular, devices in Ophthalmological field. The presoaked soft contact lenses (Bionite Lens) by 1% pilocarpine,10% phenylnephrine. 1% homatropine, and 1% atropine for 4 minutes are inserted into the albino rabbit and the size of pupil was measured using mm. caliper under the dim red light in the dark room. Hourly measurements were carried out and were stopped in each subject when the pupil size of both eyes had returned to normal. The pupil size of control group, which only the above drug were instilled into the conjunctival cuI de sac, was also measured as the same method. As conclusion using soft contact lens in the therapeutic purpose, it potentiate the effect of medication and prolong the time of drug effect compared with the control groups.
