We report a case of ciliary body melanocytoma in a Korean patient, which presented as an intermittently painful pigmented iris mass and was successfully managed by iridocyclectomy. A 52-year-old healthy man presented with an irregularly-shaped and heavily-pigmented mass at the iris root of his right eye. Visual acuity of the right eye was 20/20 with normal intraocular pressure. Ultrasound biomicroscopy showed a 1.5x1.3-mm ciliary-body mass with extension into the iris root. Iridocyclectomy with scleral resection under a lamellar scleral flap was performed, and the histopathologic features of the resected tissue were consistent with melanocytoma of the ciliary body. The patient's visual acuity remained 20/20 with good postoperative cosmesis. During one year of follow-up, no signs of tumor recurrence were seen, and the patient reported resolution of the intermittent ocular pain in the involved eye.

PURPOSE: To evaluate the characteristics of peripheral anterior synechiae (PAS) in primary angle-closure glaucoma (PACG). METHODS: We reviewed the charts of 155 patients (244 eyes) with PACG. We divided these patients into one of four clinical subtypes: acute angle-closure glaucoma (ACG), chronic ACG, angle-closure hypertension, and ACG suspect. The prevalence, extent, and location of PAS were evaluated according to PACG subtypes. Correlation analysis was used to evaluate relationships between the highest IOP level without treatment and the extent of PAS. RESULT: The average degree of angle-closure with PAS was 14.6+/-9.1 in eyes that were classified as ACG suspect, 83.8+/-48.3 in angle-closure hypertension, 140.5+/-31.3 in acute ACG, and 180.3+/-31.9 in chronic ACG (ANOVA test, P<0.05). PAS was most frequently found in the superior part of the eye, especially from 12 to 1 o'clock. The incidence of broad PAS (PAS over 30 degrees in width) was highest in superior part, but the medium and narrow PAS (PAS limited to within 30 degrees in width) was distributed throughout all 12 sectors relatively equally. Prior to a laser iridotomy (LI) and other medical treatments, a positive correlation was found between the highest IOP (intraocular pressure) levels and the extent of PAS in chronic ACG (r=0.423, P<0.0001). However, statistically significant relationships were not found between the highest IOP levels before treatment and the extent of PAS in any of the other clinical subtypes. CONCLUSIONS: Our results suggest that acute and chronic ACG patients are most likely to have a greater extent of PAS than patients in the angle-closure hypertension or ACG suspect subtypes. PAS may be narrower in earlier stages and broader in later stages. PAS was also found most frequently in the superior part of the eye. The extent of synechial closure of the angle may play a role in raising IOP levels in later stages of the disease rather than early on.

PURPOSE: To compare conventional laser peripheral iridotomy (LPI) and LPI combined with laser peripheral iridoplasty in eyes with primary angle closure suspect (PACS) by assessment of anterior chamber dimensional changes using a Pentacam. METHODS: Forty-eight eyes of 24 subjects with bilateral PACS were recruited consecutively. Each eye was randomly allocated to treatment with conventional LPI, argon LPI only, or LPI plus iridoplasty, which consisted of simultaneous argon LPI and peripheral iridoplasty. Anterior chamber measurements were performed on each eye using a Pentacam, both before and after treatment. Mean anterior chamber depth (ACD), anterior chamber volume (ACV), and anterior chamber angle were measured, and topographic ACD analysis was performed. Results were compared between the two treatment groups. RESULTS: After treatment with either conventional LPI or LPI plus iridoplasty, the mean ACD and ACV increased significantly. Topographic ACD analysis revealed that the mid-to-peripheral ACD increase was significantly greater in the LPI plus iridoplasty group than in eyes treated with conventional LPI. Intraocular pressure changes and post-LPI complications did not differ between the groups. CONCLUSIONS: Compared with conventional LPI, our study showed that LPI plus iridoplasty improved the mid-to-peripheral ACD increase. This procedure may have a role as an adjunct for reducing angle closure by simultaneously eliminating pupillary and non-pupillary block components.
