PURPOSE: To report a case of keratoconjunctivitis induced by Dieffenbachia plant sap. CASE SUMMARY: A 44-year-old woman presented with severe ocular pain and decreased visual acuity which developed after she accidentally got Dieffenbachia plant sap in her left eye. During her initial evaluation, visual acuity was 0.4 in her left eye. On slit lamp examination, we found that she had moderate injection of the conjunctiva, an epithelial defect, and fine needle-like blue crystals in the stromal layer of the cornea. The patient was treated with topical steroids and antibiotics. We checked the treatment response using a regular slit lamp examination. Six days after the injury, all of the findings which were observed on the first day had resolved except the needle-like blue crystals in the stromal layer of the cornea. These gradually disappeared from the cornea 11 days after the accident. After six weeks, the crystals in the stromal layer had completely resolved. She maintained good visual acuity during this time. There was no opacity noted in her cornea. CONCLUSIONS: We experienced a case of keratoconjunctivitis induced by Dieffenbachia plant sap. This sap caused severe ocular pain and a reversible decrease in visual acuity when in contact with the eye.

Journal of the Korean Ophthalmological Society 2014;55(7):984-990
PURPOSE: To investigate clinical availability of AL-Scan(TM) (Nidek, Gamagori, Japan) by comparing corneal refractive power with AL-Scan(TM), Autokeratometer(TM) (Topcon KR-1, Tokyo, Japan) and Pentacam(TM) (Oculus, Wetzlar, Germany) devices. METHODS: Seventy-one patients (142 eyes) who visited our hospital for refractive surgery were tested using AL-Scan(R), Autokeratometer and Pentacam(R) and corneal refractive power was compared among devices. RESULTS: When comparing measurements with AL-Scan(R), Autokeratometer and Pentacam(R), the mean corneal refractive power was 43.37 +/- 1.32 D (2.4 mm zone), 43.35 +/- 1.32 D (3.3 mm zone), 43.36 +/- 1.35 D, and 43.35 +/- 1.36 D respectively and showed no significant differences. Corneal refractive power had strongly positive linear correlation (p < 0.001) and Bland-Altman plots showed high degree of agreement among AL-Scan(R), Autokeratometer and Pentacam(R) devices. CONCLUSIONS: Because measuring ocular biometry with AL-Scan(R) including axial length, intraocular lens power calculation and topography simultaneously is possible, clinical use is convenient. Corneal refractive power was not different when compared with autokeratometer and Pentacam(R) devices, thus, AL-Scan(R) can be used in the clinical environment.

Korean Journal of Ophthalmology 2014;28(6):444-450
PURPOSE: To compare the refractive results of cataract surgery measured by applanation ultrasound and the new partial coherence interferometer, AL-scan. METHODS: Medical records of 76 patients and 104 eyes who underwent cataract surgery from January 2013 to June 2013 were retrospectively reviewed. Biometries were measured using ultrasound and AL-scan and intraocular lens power was calculated using the SRK-T formula. Automatic refraction examination was done 1 month after the operation, and differences between the ultrasound group and AL-scan group were compared and analyzed by mean absolute error. RESULTS: Mean axial length measured preoperatively by the ultrasound method was 23.53 +/- 1.17 mm while the lengths measured using the AL-scan were 0.03 mm longer than that of the ultrasound group (23.56 +/- 1.15 mm). However, there was not a significant difference in this finding (p = 0.638). Mean absolute error was 0.34 +/- 0.27 diopters in the ultrasound group and 0.36 +/- 0.31 diopters in AL-scan group, which showed no significant difference (p = 0.946) in precision of predicting postoperative refraction. CONCLUSIONS: Although the difference was not statistically significant, intraocular lens calculations done by the AL-scan were nearly similar in predicting postoperative refraction compared to those of applanation ultrasound, however more precise measurements may be obtained if the axial length is longer than 24.4 mm. Except in the case of opacity in the media, which makes obtaining measurements with the AL-scan difficult, AL-scan could be a useful biometry in cataract surgery.

Wilms' tumor is malignant renal tumor, originated from undifferentiated mesonephric blastema. Adult Wilms' tumor, unlike that of childhood, is a rare disease and a total of l67 cases have been reported in the world medical literature until 1980. Diagnosis of adut Wilms` tumor is very difficult preoperatively and the pathologic hallmark is the presence of abortive or embryonal glomerulotubular structure with an immature spindle cell stroma. The therapeutic guidelines and surgical principles that govern childhood Wilms' tumor should be applied to adult Wilms' tumor. We reported a case of Wilms' tumor developed in 34 year-old male patient complaining of right flank pain with gross hematuria for 2 months.

The renal oncocytoma is a rare benign tumor arising from the proximal tubular cells and has recently become a recognized clinical and pathologic entity. The feature of this tumor includes the tendency to (1) be incidental finding, (2) be large in size, (3) have well defined borders, (4) exhibit benign clinical behaviors. Here, we report a case of renal oncocytoma which was found incidentally due to pelvic inflammatory disease of a 37-years-old woman, who was treated with the radical nephrectomy.

PURPOSE: We report a case of dexamethasone intravitreal implant (Ozurdex(R); Allergan, Inc.) fragmentation during the injection procedure in macular edema due to central retinal vein occlusion. CASE SUMMARY: A 57-year-old man visited our hospital for visual disturbance in his right eye. The patient's best-corrected visual acuity was 0.02 in the right eye and 1.2 in the left eye. After fundus examination, the patient was diagnosed with central retinal vein occlusion with macular edema, thus bevacizumab was injected in the right eye. However, the macular edema did not improve, and a dexamethasone intravitreal implant was injected in the right eye. Immediately after the dexamethasone intravitreal implant injection, on fundus exam, the drug was observed to be fragmented into 3 pieces without any additional treatment. After 2 months, the patient's best-corrected visual acuity was 0.4 in the right eye and 1.2 in the left eye. Macular edema decreased according to optical coherence tomography. CONCLUSIONS: A case of dexamethasone intravitreal implant fragmentation during an injection procedure has not been previously reported in Korea. Although the drug fragmented, the treatment was effective without complications.

PURPOSE: To investigate the clinical availability of AL-Scan(R) (Nidek, GAMAGORI, Japan) by comparing anterior segment parameters measured with AL-Scan(R) and Pentacam(R) (Oculus, Wetzlar, Germany). METHODS: Seventy-three patients (117 eyes) who received refractive surgery at our hospital were tested with AL-Scan(R) and Pentacam(R). We compared measurements including anterior chamber depth, central corneal thickness, white-to-white, and corneal curvature. RESULTS: When comparing measurements obtained with AL-Scan(R) and Pentacam(R), the anterior chamber depth (p < 0.001), central corneal thickness (p < 0.001) and 2.4 mm zone K value (p = 0.038) showed significant differences; the white-to-white (p = 0.348) and 3.3 mm zone K value (p = 0.429) showed no significant differences. All AL-Scan(R) and Pentacam(R) parameters had a strong positive linear correlation (p < 0.001). The Bland-Altman plots showed a high degree of agreement between AL-Scan(R) and Pentacam(R) in all parameters except for anterior chamber depth. CONCLUSIONS: AL-Scan(R) is convenient to use clinically because simultaneous measurements of ocular biometry including axial length, intraocular lens power, and topography are possible. However, because differences in some anterior segment parameters exist when compared with Pentacam(R), measurements with AL-Scan(R) may require comparisons with other instruments.

PURPOSE: To report a patient diagnosed with adult-onset vitelliform dystrophy (AOVD) who received an intravitreal injection of bevacizumab in both eyes. CASE SUMMARY: A 47-year-old female presented with blurred vision and metamorphopsia in both eyes. On color fundus photograph, small, round, yellowish dots on the foveola and subreitnal fluid were observed. Optical coherence tomography (OCT) showed thick hyperreflective structures in the retinal pigment epithelium (RPE) layer with serous retinal detachment and subretinal fluid. Despite an intravitreal injection of bevacizumab on both eyes, anatomical improvement was not observed on fundus photography and OCT.
