The near point of accommodation of 500 normal Koreans aged 8 to 70 was measured for the monocular and binocular states. Push-up method with Slataper's one-two line card was used. Calculation for the near:point was measured by Prince rule with AD phoropter. The results were divided into 15 age groups as follows; 1.

The age group of 56 to 59 ; The range of monocular accomIllodative power was 1.8D. to 0.7D. The mean value was 1.0D. The range of binocular accommodative power was 2.8D. to 0.7D. The mean value was 1.5D. The excess of binocular accommodative power was 0.5D. 14. The age group of 60 to 63 ; The range of monocular accommodative power was 1.2D. to 0.4D. The mean value was 0.7D. The range of binocular accommodative power was 1.8D. to 0.5D. The mean value was 1.0D. The excess of binocular accommodative power was 0.3D. 15. The age group of 64 to 70 ; The range of monocular accommodative power was 1.0D. to 0.2D. The mean value was 0.6D. The range of binocular accommodative power was 1.6D. to 0.4D. The mean value was 0.8D. The excess of binocular accommodative power was 0.2D. The human ocular occommodative power was decreased according to the increasing age. The binocular accommodative power was larger than the monocular accommodative power. The excess between binocular and monocular accommodative power was also decreased according to the increasing age. In all age group, the mean excess between binocular and monocular accommodative power was about 1.0 diopter that was more or less larger than the Duane's. In the age group of 50 years below, these values were larger than the Duane's. In the age group of 50 years above, these values were similar to the Duane's.

Two kinds or intraprostatic stent (Prostakath and Nissenkorn catheter) were inserted under local anesthesia in 17 patients for 20 times who had benign prostatic hyperplasia. Within 1 month after insertion of the stents. the results are good in 10 of 17 patients. fair in 4 and poor in 3 from the view points of improvements in urine flow and voiding symptoms. Of 9 patients in whom the stents have been inserted longer than 6 months. 4 are good. 2 are fair and 3 are poor in the results of long term insertion. It seems that this method is applicable as s definitive method for benign prostatic hyperplasia if there is a few progressions in the location where this stent is inserted. in the quality or stent material and in the easy way to change the stent.

The aims of the our study are investigation of the average value of the refraction, anterior chamber depth(ACD), axial length(AL), and the interrelationship of refraction, ACD, AL, weight and height of normal newborn infant. Objects of this study are 236 eyes of 118 normal newborn infants that have been examined with retinoscope under the cycloplegia and the axial length and anterior chamber depth have been measured by ultrasonogram. And so we gained following results. The average value of refraction(+1.85 +/- 1.86D), the average value of the AL(17.5 +/- 0.68mm) and the average value of ACD(2.62 +/- 0.21mm) did not show significant difference between male and female newborn infants. The correlation coefficient between AL and ACD. refraction and AL, weight and AL, and height and AL were 0.326(P<0.001), -0.305(0.0010.1).

Tunica albuginea cyst is a rare disease and the most of which are benign lesion unlike most testicular mass. We report a 65-year-old man was admitted with testicular pain, tenderness and palpable mass. Preoperative ultrasonography demonstrated well marginated, cystic lesion in right testis, about 2.0 x 2.8 x 3.3 cm in size with partially thin walls. Orchiectomy was done and diagnosis was made by patho-histologic findings.

Optic pits are congenital craterlike holes or indentation in the surface of the optic disc. They are oval in shape and located in the inferior temporal quadrant of the optic disc. The authors experienced a case of congenital optic pit of the left eye of 18 year old male-patient. Fluorescein angiography showed hypofluorescence of the pit in early arteriovenous phase, becomming hyperfluorescence in the late phase. Ophthalmoscopic view of the diseased eye showed no abnormality of macular area. There was no visual field defect except the enlarged physiologic blind spot. Here we briefly report a case of congenital optic pit. referring the literature relating to the optic pit.

Sympathetic ophthalmia is a rare, diffuse, granulomatous inflammation of the entire uvea, usually bilateral, which occurs days, months, or years after penetrating ocular injury or intraocular surgery. This presented case was a 34 years old male patient injured his left eye suspecting a scleral laceration. The exciting eye(left) was eviscerated 8 days after injury and sympathetic eye(right) was developed sympathetic ophthalmia 8 weeks after injury. A brief review of the related literatures is presented.

Photorefraction was performed in 96 cases(191 eyes) after instillation of tropicamide and cyclopentolate for the purpose of screening procedure. And then refraction was also carried out by retinoscope. From this comparison study, phtorefraction provided data which were very close to those obtained from the conventional retinoscopy.

A 45-years-old woman complained mild right flank pain and easy fatigability. Right abdominal bruit was heard by auscultation. CT and angiography revealed a huge venous dilatation in renal sinus measuring 10.2cm in diameter. And similar findings were shown in MRI. We performed nephrectomy and confirmed arteriovenous fistula in main renal artery and vein.

The vitreoretinopathy with familial tendency was first described by V.G.Criswick and C.L. Schepens in 1969. The disease is slowly progressive and can be clinically grouped into 3 stages according to the severity of ocular manifestation. The etiology of this disease which is similar to the other vitreoretinopathy without the history of prematurity and oxygen supply is unknown. Two sibling patients suggesting to have the familial exudative vitreoretinopathy were reported and reviewed herein with their clinical features.
