ABSTRACT
The purpose of this study was to estimate average lacrimal gland size on computed tomography in korean. The subjects were 137 Koreans who were checked orbital CT in Department of Ophthalmology, Soonchunhyang University School of Medicine from June 1990 to August 1994. The average width of lacrimal gland was 17.15 +/- 1.75mm, A-P length was 9.81 +/- 1.65mm and thickness was 4.57 +/- 0.99mm. The average width, A-P length and thickness of lacrimal gland were not statistically different between males and females(p>0.05).

The lymphangioma is a benign vascular tumor and, like hemangioma, represents a hamartomatous growths. The site of predilection include the head, neck. and axillae. Lymphangiomas tend to involve the bulbar conjunctiva as well as the eyelid and orbit. Histopathologieally three types of lymphangioma are encountered: demal, cavernous and cystit types. The clinical signs are proptosis, diffuse hematoma of eyelid and subconjunctival hemorrhage. Asymptomatic cases can be observed. The authors experienced a case of multiple lymphangiomas on the right supraorbital area in a 14-year-old man and reported light microscopic and electron microscopic findings of the lymphangioma.

The familial exudative vitreoretinopathy is an autosomal dominantly inherited disease and shows abnormalities of the retina and vitreous. It affects both eyes in most cases, but the involvement is often asymmetric. Thus it is important to screen familial members carefully, since they may have only mild, nonprogressive changes in the retinal periphery. It is important to know family history of the disorder and history of prematurity or oxygen supplementation, since the clinical features are most similar to retinopathy of prematurity. The authors experienced three cases of familial exudative vitreoretinopathy in a 2-year-old girl with cryotherapy and her father and her brother with asymptomatic familial exudative vitreoretinopathy that has retinal vascular avascular zone of peripheral retina.

Chronic progressive external ophthalmoplegia(CPEO) is rare syndrome, which is characterized by slowly progressive blepharoptosis, paralysis of extraocular muscle and has involvement of other organs, particularly the retina, heart, endocrine gland, and bony skeleton. Histological examination of muscle showes characteristic ragged red fibers. Electron microscopy reveals a number of abnormal mitochondria which contain paracrystalline inclusion bodies. We experienced a 50-year-old female with CPEO, that was pathologically proven by electron microscopy and bilateral levator levator advancements were given for ptosis.
