The intraocular pressure (IOP) in 115 cases of extracapsular cataract extraction (ECCE) and ciliary sulcus fixation of posterior chamber lens implantation was measured more than 2 months postoperatively. These results were compared to the unoperated fellow eyes, as well as to a group of 14 patients who had ECCE and implantation of an anterior chamber lens. The posterior chamber lens implanted eyes demonstrated a significant IOP reduction after surgery compared to the unoperated fellow eyes and the anterior chamber lens implanted eyes. In the posterior chamber lens implanted eyes, there was a significant IOP reduction after surgery in all age groups and there was a significant IOP reduction in the eyes with a 2 to 6 months and a 7 to 12 months follow-up after surgery, but no IOP change in the eyes with more than 1 year follow-up after surgery. We concluded that in the case of ECCE and ciliary sulcus fixation of posterior chamber lens implantation, IOP was initially reduced after surgery, but approarhed the preoperative level over a period of time.

The safety and success rate of trabeculectomy using fornix-based conjunctival flaps were investigated. Patients with chronic angle-closure glaucoma(22 eyes), primary open-angle glaucoma(10 eyes), secondary glaucoma(4 eyes) and ocular hypertension(1 eye) had a trabeculectomy with a fornix-based conjunctival flap. We analyzed the results of these 37 eyes and compared them witih those of trabeculectomy using a lmbus-based codjunctival flap Trabeculectomy was equally successful(intraocular pressure, Humans ; Trabeculectomy*

Posterior lip sclerectomies were performed in rabbits and cytosine arabinoside (Ara-C) was applied by topical instillation or subconjunctival injection. In both groups, the mean intraocular pressure (IOP) of the treated eyes was significantly lowered at postoperative week 1 and 2, but there was no significant difference between the mean IOP of the control eyes and that of the treated eyes at postoperative week 3 and 4. In both groups, at postoperative week 2, the sclerectomy sites of the control eyes were totally occluded by granulation tissue, but those of the treated eyes were partially replaced by granulation tissue. At postoperative week 4, the sclerectomy sites of the treated eyes were totally occluded by the granulation tissue ultimately in both groups. There were no differences in the mean IOP and the histologic finding of the treated eyes between the topical instillation group and the subconjunctival injection group. We concluded that either topical instillation or subconjunctival injection of Ara-C can delay wound healing at the surgical site after glaucoma filtering surgery in rabbits.

115 cases of extracapsular cataract extraction(ECCE) and ciliary sulcus fixation of posterior chamber lens implantation had intraocular pressure(IOP) measurements recorded more than 2 months postoperatively. These results were compared to the unoperated fellow eyes, as well as to a group of 14 patients who had ECCE and implantation of an anterior chamber lens. The posterior chamber lens implanted eyes demonstrated a significant IOP reduction after surgery compared to the unoperated fellow eyes and the anterior chamber lens implanted eyes. In the posterior chamber lens implanted eyes, there was a significant IOP reduction after surgery in all age groups and there was a significant IOP reduction in the eyes with from 2 to 6 months and from 7 to 12 months follow-up after surgery, but no IOP change in the eyes with more than 1 year follow-up after surgery. We concluded that in the cases of ECCE and ciliary sulcus fixation of posterior chamber lens implantation, IOP was reduced a while after surgery, but approached to preoperative level as time went on.

PURPOSE: To assess the proper differential diagnosis and treatment of scleritis with scleral melt following pterygium excision. METHODS: A retrospective study through a review of medical records of 5 patients diagnosed with surgically induced necrotizing scleritis (SINS) after pterygium excision and treated with systemic immunosuppressant and steroid. RESULTS: All the patients responded to the treatment and showed significant improvement. CONCLUSIONS: Immunosuppressive treatment without surgical intervention is effective in resolution of SINS after pterygium excision.

Posterior lip sclerectomies were performed in rabbits and cytosine arabinoside (Ara-C) was applied by topical instillation or subconjunctival injection. In both groups, the mean intraocular pressure (lOP) of the treated eyes was significantly lower at postoperative week 1 and 2, but there was no significant difference between the mean lOP of the control eyes and that of the treated eyes at postoperative week 3 and 4. In both groups, at postoperative week 2, the sclerectomy sites of the control eyes were totally occluded by granulation tissue, but those of the treated eyes partially replaced by granulation tissue At postoperative week 4, the sclerectomy sites of the treated eyes were totally occluded by the granulation tissue ultimately in both groups. There were no differences in the mean lOP and the histologic finding of the treated eyes between the topical instillation group and the subconjuctival injection gorup. We concluded that either topical instillation or subconjunctival injection of Ara-C can delay wound healing at the surgical site after glaucoma filtering surgery in rabbits.

We used the fluorophotometry to investigate the corneal epithelial barrier function after excimer laser photorefractive keratectomy (PRK). Twenty-five eyes of 21 subjects (13 women, 8 men) underwent PRK to correct rnyopia. Corneal epithelial healing time was measured and corneal epithelial permeability to sodiurn fluorescein was evaluated by fluorophotoinetry at I, 2, and 3 weeks after surgery. The corneal epithelial permeability increased significantly 1 week after surgery and returned to preoperative level 2 weeks after surgery. The permeability differences according to epithelial healing days and corrected diopters were not statistically significant(p>0. 05). These results suggest that PRK delays complete reconstruction of corneal epithelial barrier function. The corneal epithelium regained its functional barrier 2 weeks after PRK in patients, so, at least, during the first 2 weeks, care should be taken to miniinize further epithelial trauma from topical inedication or surgical manipulation.

The visual, refractive, and keratometric results of radial keratotomies (RK) in 10 high myopic eyes of over 10 diopters(D) were evaluated. The mean follow-up period was 6.7 months with a range of 3 to 12 months. Before surgery, the mean spherical equivalent(SE) was -16.8 D and the postoperative mean change in SE was 7.9 D. In all cases postoperative uncorrected visual acuity and corrected visual acuity with tolerable glasses were improved. In 4 of the cases, best-corrected visual acuity was improved as well. RK appears to be a safe and effective procedure for eyes with high myopia of over 10 D to achieve better corrected visual acuity than with corrective lenses as well as for eyes with moderate myopia to be closer to emmetropia.
