Timolol malate, a potent beta-adrenergic antagonist, reduced intraocular pressure. The use of timolol malate ophthalmic solution was reduced intraocular pressure without pupillary alteration, alteration of anterior chamber and fluctuating myopia and hyperemia compaired with other reducing agents. We compair the effects of timolol maleate ophthalmic solution with pilocarpine and epinephirine solution in the view of the changes in intraocular pressure. We divided 30 white rabbits randomly into 3 groups, group 1 was 0.5% timolol malate, group 2 was 2% pilocarpine, and group 3 was 0.5% epinephrine. Each solution was instilled one drop on right eyes daily. and cheeked intraocular pressure after 15 minitues, 1 hour, 3 hours, 8 hours and 24 hours for 1 week duration. We evaluated the statistical significance of all changes according to the T-test and P-value. The results of observation as follow; In group I, the mean intraocular pressures was reduced 1 hour, 3 hours, 8 hours after instillation and the effect lasted 24 hours after dropping(p<0.05). In group 2, the similar result as group 1, but lasting effect was shorter than group 1 (p<0.05). In group 3, the mean intr.a.ocular pressure was reduced 8 hours after instillation (p<0.05). And compair with group 1 and group 2 we no statistical significance (p>0.05).

Global orbital infarction is a rare disorder resulting from ischemia of the intraocular and intraorbital structures due to hypoperfusion of the ophthalmic artery and its branches. The syndrome can occur with common carotid artery occlusion, orbital mucormycosis, giant cell arteritis and complications of surgery and manifests protosis, ophthalmoplegia, and blindness. Protrusion of the eyeball(proptosis) is the result of expansion of tissue within orbital cavity and is the hallmark of orbital diseases. Expansion lesions may be benign or malignant and may arise from bone, muscle, nerve, blood vessel, or connective tissue. We report a case of combined ophthalmic artery occlusion, optic neuropathy, and third nerve palsy involving pupil in a 32-year-old patient with unilateral idiopathic proptosis following anterior choroidal aneurysm operation, and discuss possible mechanism with literature review.

Real-time ultrasound-guided fine-needle aspiration biopsy in 137 solid breast masses was performed. Sonographic findings were categorized into three group and aspirates were categorized into three cytologic groups. The cytologic result was reported benign masses (cytologic group 1) in 71 cases (52%), malignant masses (cytologic group 2 and 3) in 44 cases (32%) and insufficient specimens in 22 cases (16%). Insufficient specimens were treated as benign masses. Excisional biopsy in 44 malignant masses and 3 benigh masses according to cytologic results, clinical findings and follow up study was performed. The result was reported 41 malignant masses and 6 benign masses. Based on cytologic criteria, sensitivity for detection of malignancy was 93% and specificity was 94%. In conclusion, the high specificity provided by ultrasound-guided fine-needle aspiration biopsy could markedly reduce unnecessary surgical excisions for benign masses and it should be routinely performed, since it can give physical and emotional benefits to patients and lead to earlier and cost effective diagnosis of breast cancer.

PURPOSE: We evaluated both the patients and the normal volunteers to determine the diagnostic criteria of subacromial impingement syndrome. MATERIALS AND METHODS: We analyzed the radiologic finding of Thirty degree of caudal tilt view (TCTV) and Supraspinatus outlet view (SOV) of 100 shoulders from 85 patients with clinically proved subacromial impingement syndrome and normal 100 shoulders from 60 volunteers. RESULT: In TCTV, the protrusion of acromion below the line of extension from inferior surface of clavicle was shown in 94% of the patient group and 48% in normal group. Sharp tip of acromial protrusion was detectable in 55.3% of the patient group and 10.4% in normal group. In SOV, curved type of acromion was seen in 53% of the normal and 50% in patient group. Hooked type of acromion was detected in 3% and 31% of the normal and patient group, respectively. CONCLUSION: Protrusion of acromion at TCTV itself was not a criteria of subacromial impingement syndrome, but more than 7 mm below the line of extension from inferior surface of clavicle was meanigful. In SOV, hooked type of acromion was a criteria of subacromial impingement syndrome but curved type is was not a finding of diagnostic significence. Acromial spur formation on TCTV and SOV was important criteria of subacromial impingement syndrome.
