Comparison of Sugical Outcome between Early and Delayed Repair of Orbital Wall Fracture

PURPOSE: We analyzed the preoperative and postoperative clinical findings of orbital wall fracture patients between the group operated within 2 weeks (early group) and the group operated 3 weeks or later (delayed group). METHODS: Eighty three patients who had been operated from January 1997 to December 2001 were included, 68 patients were early group and 15 patients were delayed group. We analyzed retrospectively the degree of diplopia, limitation of extraocular motility and enophthalmos for more than 6 months following surgery. RESULTS: Orbital wall fracture predominantly occurred in male than in female (p>0.05), and mostly between 21 and 40 years old. The main cause was from violence and traffic accidents. The major coexisting diseases were head trauma and fractures of low extremities, especially in the group of delayed operation. The common locations of fracture were either inferior wall or combined inferior and medial walls. The early group showed less severe preoperative clinical states and better outcomes of postoperative improvement than the delayed group. However, there was no statistically significant difference between two groups in the degree of postoperative limitation of extraocular motility and enophthalmos. CONCLUSIONS: The early group tended to be less severe preoperatively and showed better postoperative outcome than the delayed group. However, the repair of orbital wall fracture was be indicated to improve clinical states even after 3 weeks following injury.

The Effect on Early Visual Outcome of Corneal Cap Attachment with Brushing after LASIK

PURPOSE: This study was to investigate the effect on early visual outcome of corneal cap attachment with brushing after LASIK. METHOD: We studied 40 eyes of 20 patients who received LASIK from April, 1998 to March, 1999. Early visual acuity was measured in the first, second and third day after LASIK between the group that received brushing procedure and the group that didn't. RESULT: The consecutive group that received brushing procedure showed considerable increase in recovery rate of visual acuity compared to the control group that did not receive brushing procedure on the first day (P0.05) after LASIK. CONCLUSION: We think that corneal cap attatchment with brushing helps early visual recovery and further investigation in this study is needed.

Effectiveness of Washing Nasolacrimal Duct as an Additional Therapy after Dacryocystorhinostomy

The surgical methods for the obstruction of nasolacrimal duct include conventional dacryocystorhinostomy and nasal endoscopic dacryocystorhinostomy.The authors followed 52 eyes of 54 patients who had undergone conventional or endoscopic dacryocystorhinostomy to compare the surgical success rate, between the group whose nasolacrimal duct was washed with normal saline and the control group without irrigation. Nasal cavity of all patients were examined for the abnormalities such asnasal septal deviation, hypertropy of middle concha, ethmoid sinusitis and nasal polyp.The patients with those abnormalities were excluded. There was significant difference between the two groups, showing better outcome in the group with nasal irrigation. These results suggest that washing NLD after the dacryocystorhinostomy may be effective as an additional therapy to enhance the success rate of operation.

Bilateral Complicated Microphthalmia in a Family

Complicated microphthalmos can be diagnosed when a reduction in global dimension is combined with other structural anomalies. These include corneal opacity or staphyloma, cataract, aniridia, corectopia, persistence of pupillary membrane or the tunica vasculosa lentis and hyaloid vessel, thickening or ossification of the choroid and various retinal anomalies. Complicated microphthalmos is frequently hereditary and the transmission may be either as an autosomal dominant or recessive or as a sex linked recessive trait. Four cases of bilateral complicated microphthalmos with cataract were found in a family.

Clinical Results of 125 Eyes of Posterior Chamber Lens Implantation

From February 1986 to October 1988, 125 cases of planned ECCE with posterior chamber lens implantation were performed in Chosun University Hospital, and they had been followed up for more than 6 months. The results were as follows: 1. In the 125 cases of posterior chamber lens implantation, the number of patients were 87 male and 38 female. The most prevalent age groups were age 50s to 60s for both men and women. 2. Posterior chamber lens power ranged from +17.0D to +22.5D and the most frequently used posterior chamber lens power was from +19.0D to +20.0D(83 eyes, 66.4% of 125 cases) in both male and female. 3. Postoperative corrected vision with posterior chamber lens was improved up to 0.6 or better in 87.5%. 4. The mean spherical equivalent o final postoperative refractive state was observed in - 0.75 +/- 1.54D. 5. Postoperative complications were pupil distortion(12.8%), increased intraocular pressure(4.0%), tilted chamber lens(4.0%), cystoid macular edema(2.4%) and after-cataract(1.6%).

A Case of Cysticercosis in the Anterior Chamber of the Eye

We investigated a case of cyst icercosis in the anterior chamber of right eye in a 45 year-old Korean man. Surgical intervention was performed through the superior limbal incision and cyst, about 5 mm diameter of size. was extracted from the anterior chamber. The microscopic studies revealed a cysticercus cellulosae. Three months after operation, visual acuity improved from 0.4 to 0.9 and the ocular functions are satisfactory. We report here a case of cysticercosis with a brief review of literature.

Clinical Studies on Hyphema in The Complications of Cataract Extraction

The history of surgical treatment of cataract extends back at least Before Christ. In 1748 Jacques Daviel, French ophthalmic surgeon, was attempted to cataract extraction with modern operating techniques and since then development of operation methods, techniques and instruments were contributed to recovery of the loss of vision. Although the occurrence of during and postoperative complications of cataract extraction diminish, cataract complications still remain troublesome in the minds of cataract operators. The authors reported the result of hyphema in the many complications of cataract extraction for the 7 of the 47 eyes(42 cases), which were operated from January 1976 to August 1977, using the sex, types of cataract, age, methods of operation, onset and procedure.

3 Cases of Orbital Tumor

3 cases of orbital tumors were presented, which were confined respectively as papillary adenocarcinoma, pseudotumor and mixed tumor in the histopathological findings. CASE 1: Papillary adenocarcinoma had been noticed in the left eye of a 66-year-old woman from about 4 months previously. Visual acuity was 0(O.D.), 0.3(1.2)(O.S.) and left eye ball was almost protruded out of the orbit. There was a coin-lesion, which was considered metastatic lesion from the eye, in the right upper lung field. Evisceration of the orbit which was almostly destroyed was performed successfully. No incidence of recurrence can be disclosed untill now, 16 months after surgery, and lost in follow up. CASE 2: Pseudotumor was developed in the left eye of a 33-year-old male. Visual acuity was 0.06(O.S), 1.2(O.D.). Severe choked disc and optic nerve atrophy were showed. Exophthalmometry: 24mm(0.5.), 18mm(0.D.). It was necessitated evisceration of the orbit because of the tumor was placed in the almost entire orbital space. Follow up study were impossibJe. CASE 3: In the left eye of a 51-year-old woman, mixed tumor had been developed from about 8 years previously. Visual acuity was 1.0(O.S.) and F.L.P.(O.D.), exophthalmometry: 13mm(O.U.). Surgical removal was successful and lost in follow up.

The Clinical Survey of the Ocular Injuries by Traffic Accidents

Authors analysed clinically 44 patients (57 eyes) of the ocular injuries by traffic accidents among 333 In-patients who admitted to Han Gang Sacred Heart Hospital from Jan. 1972 to June 1974. 1. The incidence of ocular injuries by traffic accidens was 13.2% of all admitted patients. 2. Male (64%) was two times as much as female among the patients and they were m03tly belong to 2nd and 3rd decade. 3. The incidence of site was 41% in left eye. 4. The seasonal distribution showed that 48% of traffic accidents occurred in spring. 5. External ocular injuries; laceration or ecchymosis of lid, subconjunctival hemorrhage, and corneal laceration, were predominant (52%). 6. Ocular injuries which were combined with head trauma or facial laceration were 64% and 19% in single ocular injury. 7. The visual acuity of lower than 0.1 was 29.5% of all injured eyes.
