The Measurement of the Apparent Accommodation with AA-2000 Accommodometer

We compared the apparent accommodative power of 35 pseudophakic patients(43eyes) receiving posterior chamber lens in the bag with 34 normal persons(34eyes) by using AA-2000 accommodometer and evaluated the correlation between apparent accommodation and various factors like age, corrected visual acuity, refractive error, pupillary diameter, anterior chamber depth, or change of the anterior chamber depth in pseudophakic eyes. The mean apparent accommodative power was 1.41 +/- 0.62 diopter(D) in pseudophakic eyes and 1.58 +/- 1.71 D in phakic eyes and there was no stastistically significant difference between two groups. However, in cases younger than 55 years old, the apparent accommodative power was 1.34 +/- 0.48 D in 17 pseudophakic eyes and 2.51 +/- 2.31 D in 14 phakic eyes and there was statistically significant(p<0.05). Among the various factors, pupillary diameter appeared to be correlative to the apparent accommodative power in pseudophakic eyes. The smaller pupillary diameter, the greater accommodative power. Otherwise, another factors were not correlative to the apparent accommodative power.

The Clinical Aspects of Blow-Out Fracture and Lyodura as an Orbital Floor Implants

From April 1989 to April 1993, 85 patients with orbital fractures were analysed. Among them, 10 patients were repaired surgically. Orbital fractures occured most frequently between the aga of 11 and 40 years. The main causes of injury were violence(41%), traffic accident (27%) and falldown injury (19%). Medial wall fractures were most common, followed by fractures of inferior wall, superior wall in order. In combined wall fracture, medial and inferior wall fracture was most frequent. The associated symptoms and signs of orbital fracture were lid laceration (32%), diplopia (29%). orbital edema(27%). traumatic iridocyclitis(22%). The subciliary approach was used for repair of the fracture. Early surgical intervention was done within 10 days in all cases. The insertion of Lyodura was performed in 9 patients. and calvarian bone graft was fashioned and placed over the defect in 1 patient. Insufficient correction of enophthalmos in 1 patient, lower eye lid retraction in 1 patient, residual diplopia in far upgaze in 2 patients were encountered as postoperative complications.

A Cytologic Diagnosis of Bilateral Orbital Malignant Lymphoma

Malignant lymphoma is a malignant tumor involving the lymphoid cells in lymph node, which also involve the gastrointestineal tract, skin, respiratory system and orbit etc. Malignant lymphoma rarely involves the orbit, furthermore, both orbital involvememt is very rare, whether it is primary or systemic. We experienced a case of systemic malignant lymphoma involving both orbits in a 66-year-old female which was diagnosed with needle aspiration cytology and improved with systemic anticancer drugs. We report this unusual case with literature review.
