PURPOSE: To assess whether a 4 mg/0.05 ml intravitreal triamcinolone acetonide injection can reduce the IOP elevation compared to conventional 4 mg/0.1 ml injection. METHODS: A retrospective case study was performed in 48 patients (48 eyes) who received intravitreal triamcinolone acetonide injection and who had a minimum follow-up time of six months. Patients were randomly assigned to receive 4 mg/0.1 ml or 4 mg/0.05 ml (24 patients in each group). RESULTS: Before injection, mean IOP was 13.8+/-2.2 mmHg and 13.9+/-2.4 mmHg in the 0.1 ml and 0.05 ml group. The difference in IOP elevation between the two groups was statistically significant immediately after injection (P=0.000), one hour after injection (P=0.001), and one day after injection (P=0.000). After injection, the central macular thickness decreased significantly the of two groups. The difference of the central macular thickness decrease between both groups was not statistically significant. CONCLUSIONS: An intravitreal triamcinolone acetonide 4 mg/0.05 ml injection will more quickly reduce the IOP elevation in the early phase compared to 4 mg/0.1 ml injection, while providing a similar effect on the change of central macular thickness.

PURPOSE: To evaluate long-term effects and usefulness of combined intravitreal injection of bevacizumab and panretinal photocoagulation (PRP) in patients with high-risk proliferative diabetic retinopathy. METHODS: The authors retrospectively reviewed the records of 40 patients (40 eyes) with high-risk proliferative diabetic retinopathy who had been treated with PRP alone (laser treatment group, n=20) or intravitreal bevacizumab before PRP (combined treatment group, n=20). Changes in best corrected visual acuity (BCVA), central macular thickness (CMT) and the total area of leakage from active new vessels (NVs) were compared between the groups at one, three, and six months and at one year post-treatment. RESULTS: In the combined treatment group, CMT decreased significantly at one month (p=0.021), and the areas of active NVs decreased significantly at one month (p=0.001) and three months (p=0.014) compared to those of the laser treatment group. However, there were no differences between the two groups after three months. In the combined treatment group, elevated intraocular pressures were found in three cases after one month, and there were vitreous hemorrhages in two cases after three months. CONCLUSIONS: The combined treatment showed significant early improvements in BCVA, CMT, and NVs regression for up to three months. However, long-term follow-up and additional treatment was necessary in the patients with persistent or recurred NVs and macular edema after three months.

PURPOSE: To report a rare case of choroidal metastasis from renal cell carcinoma. CASE SUMMARY: A 61-year-old man visited our clinic with the chief complaint of decreased vision in the right eye. Three years earlier, he underwent right nephrectomy due to renal cell carcinoma. Best corrected visual acuity was 0.2 in the right eye and 1.0 in the left eye. Fundoscopic examination of the right eye revealed a yellowish, dome-shaped elevated choroidal mass with serous retinal detachment, measuring 5.0 x 4.0 disc diameter and located lateral to the macular area. Systemic evaluations showed multiple lung and brain metastases. A diagnosis of choroidal metastasis from renal cell carcinoma was made for the right eye, and the patient received local treatments with oral sorafenib therapy, composed of subtenon triamcinolone injection and intravitreal ranibizumab injection. Tumor progression continued, and visual acuity declined to hand motion. Enucleation was recommended, but the patient refused and is on a regular follow-up after transpupillary thermotherapy. CONCLUSIONS: Ocular manifestation may be the initial presenting sign of a recurrent tumor, and an extensive systemic evaluation for metastatic malignancy should be performed. The present example showed a rare case of choroidal metastasis from renal cell carcinoma.

PURPOSE: To report a case of hemorrhagic lymphangiectasia treated with surgical excision and confirmed by pathologic examination. CASE SUMMARY: A 21-year-old man presented with spontaneous hyperemia of his right eye of 1 week duration. The patient had a history of tuberculous retinal vasculitis and uveitis 1 year prior, but there was no active lesion during regular follow-up. There was no history of trauma, visual disturbance, diplopia, ocular pain, or any sign of systemic disease. Slit lamp examination showed tortuous dilatation of blood-filled lymphatic vessels on temporal conjunctiva of the right eye. The lesion did not change during the 4 weeks of follow-up and local excision biopsy was made for final diagnosis and treatment. Pathologic examinations revealed thin-walled lymphatic vessels with localized dilatation which contained blood in the lumen consistent with hemorrhagic lymphangiectasia. There was no sign of recurrence until 2 months after the operation. CONCLUSIONS: Hemorrhagic lymphangiectasia should be considered in patients with recurrent or longstanding localized tortuous subconjunctival hemorrhage.

PURPOSE: To report a patient with non-arteritic anterior ischemic optic neuropathy with submacular fluid and peripapillary swelling. CASE SUMMARY: A 53-year-old patient visited our clinic complaining of acute visual loss in the right eye which began two days previously. The patient had no clinical history of ocular pain on eye movement. A relative afferent pupillary defect was observed in the right eye. Fundoscopic examination showed optic disc edema and an elevated macular lesion (1 disc diameter). Fluorescein angiography (FAG) revealed blocking by serous detachment in the peripapillary area in the early phase and peripapillary leakage in the late phase. Spectral domain optical coherence tomography (SD-OCT) showed submacular fluid and peripapillary swelling. Intravenous steroid injection was administrated. After five days of treatment, visual acuity improved to 0.2; one month later, visual acuity was 0.5. subretinal fluid absorption was observed with remaining lipid deposits. CONCLUSIONS: In non-arteritic anterior ischemic optic neuropathy, submacular fluid accumulation can occur due to destruction of retinal glial cells. Accumulation of submacular fluid can induce sudden visual loss and may predict visual prognosis. The macular area requires careful evaluation in non-arteritic anterior ischemic optic neuropathy patients.

PURPOSE: To compare the effect and complications of treatments for diabetic macular edema. METHODS: Literature review using the Korean medical database and the Korean Ophthalmological Society database was performed. Studies used consisted of patients with diabetic macular edema, comparing intravitreal triamcinolone acetonide (IVTA) injection with posterior subtenon triamcinolone acetonide (STTA) injection or intravitreal bevacizumab (IVB) injection, according to visual acuity (VA) outcomes, central macular thickness (CMT), and intraocular pressure (IOP) at 1, 3, and 6 months. RESULTS: In the three studies comparing IVTA injection with STTA injection, IVTA injection demonstrated greater improvement in VA at 1 month and CMT at 6 months. The patients who received IVTA injection had significantly higher IOP at 3 months. In the three studies comparing IVTA injection with IVB injection, IVTA injection demonstrated greater improvement in VA at 3 months and CMT at 6 months. CONCLUSIONS: The functional and anatomical improvements are achieved by IVTA injection, STTA injection, and IVB injection for diabetic macular edema, and the effect of IVTA injection is more prominent than other injection types with longer duration.
