We report a case of intraocular gnathostomiasis diagnosed by western blot assay in a patient with subretinal tracks. A 15-year-old male patient complained of blurred vision in the right eye, lasting for 2 weeks. Eight months earlier, he had traveled to Vietnam for 1 week and ate raw wild boar meat and lobster. His best-corrected visual acuity was 20/20 in both eyes and anterior chamber examination revealed no abnormalities. Fundus examination showed subretinal tracks in the right eye. Fluorescein angiography and indocyanine green angiography showed linear hyperfluorescence of the subretinal lesion observed on fundus in the right eye. Ultrasound examination revealed no abnormalities. Blood tests indicated mild eosinophilia (7.5%), and there was no abnormality found by systemic examinations. Two years later, the patient visited our department again for ophthalmologic evaluation. Visual acuity remained 20/20 in both eyes and the subretinal tracks in the right eye had not changed since the previous examination. Serologic examination was performed to provide a more accurate diagnosis, and the patient's serum reacted strongly to the $Gnathostoma$ $nipponicum$ antigen by western blot assay, which led to a diagnosis of intraocular gnathostomiasis. This is the first reported case of intraocular gnathostomiasis with subretinal tracks confirmed serologically using western blot in Korea.

We present a case of ocular toxocariasis treated successfully with oral albendazole in combination with steroids. A 26-year-old male visited the authors' clinic with the chief complaint of flying flies in his right eye. The fundus photograph showed a whitish epiretinal scar, and the fluorescein angiography revealed a hypofluorescein lesion of the scar and late leakage at the margin. An elevated retinal surface and posterior acoustic shadowing of the scar were observed in the optical coherence tomography, and Toxocara IgG was positive. The patient was diagnosed with toxocariasis, and the condition was treated with albendazole (400 mg twice a day) for a month and oral triamcinolone (16 mg for 2 weeks, once a day, and then 8 mg for 1 week, once a day) from day 13 of the albendazole treatment. The lesions decreased after the treatment. Based on this study, oral albendazole combined with steroids can be a simple and effective regimen for treating ocular toxocariasis.

Purpose: To report a case of a 60-year-old female with rhegmatogenous retinal detachment, presenting with suprachoroidal hemorrhage after vitrectomy. Case summary: A 60-year-old woman visited our clinic complaining of floaters, flashing, and blurred vision. Best-corrected visual acuity was 0.1 in her left eye, and fundus examination of her left eye revealed macula-involved retinal detachment with a retinal break at the superotemporal quadrant. She underwent cataract surgery, 23-gauge transconjunctival sutureless vitrectomy, and 14% C3F8 gas tamponade under general anesthesia. One hour after anesthesia recovery, she suddenly complained of severe pain in her left eye. The intraocular pressure measured after removal of the pressure patch from her left eye was as high as 58 mmHg. Her ocular pain improved spontaneously within 10 minutes, and the intraocular pressure decreased to 8 mmHg. Fundus examination of her left eye revealed a reddish-brown raised lesion, suggesting suprachoroidal hemorrhage. She was placed in a prone position with a pressure patch over her left eye. Bleeding through the sclerotomy site was observed 1 day after surgery. Subsequently, hemorrhagic choroidal detachment of her left eye continued to decrease without deterioration. Three weeks after surgery, the patient received an intravitreal injection of 100% C3F8 gas into her left eye. At 3 months after surgery, best-corrected visual acuity had improved to 0.8 in her left eye, and the retina was stable. Conclusions: Suprachoroidal hemorrhage may be suspected in a patient complaining of severe ocular pain after vitrectomy.

Image correction of the fluorescein angiogram with the low contrast and geometrically distorted is studied. The procedure is divided into two steps : A template matching step and a geometrical transformation step. Based on the sequential similiarity detection algorithm, more Improved matching results are obtained with edge enhanced image. For the reference points and the corresponding matchimg points, the geometrical transformationss by the use of the average value of the X, Y translational shifts and a pair of these points, respectively are described. Then the corrected images are obtained using bilinear interpolation. It is proven that the usefullness of this study for the image correction of the ocular fundus fluoresceln angiogram with low contrast and geometrically distorted mainly due to the eye movements.

A 6-year-old intact male Maltese dog presented with a history of blindness and ataxia. Neuro-ophthalmic examination revealed dilated pupils with absent pupillary light reflexes and menace response in both eyes. Mild peripapillary edema was noted in the fundus of the right eye. After magnetic resonance imaging, the dog was provisionally diagnosed with meningoencephalitis of unknown etiology. Follow-up funduscopy was performed to monitor the condition of the optic discs for three years. Despite of the treatment with prednisolone, the optic nerve progressed to atrophy and the dog couldn't restore vision.

Solar retinopathy is a rare but well-recognized clinical entity of macular damage, caused by viewing a solar eclipse or direct sun gazing. A 21-year-old man gazed at the sun for approximately thirty seconds at noon using a monocular telescope with his left eye. Forty-eight hours after sun gazing, the patient experienced symptoms of blurred vision and central scotoma in the left eye. Eight months after sun gazing, the visual acuity decreased from 1.0 to 0.1 in the left eye and the fundus examination showed a round, yellowish-white discoid lesion at the left fovea. Fluorescein angiography showed an early window defect in the fovea of the left eye, that persisted without size change during the late phase resulting from atrophy of the retinal pigment epithelium. A small, central scotoma of the left eye was also found in the visual field test. The visual acuity was unchanged at the end of a one-year follow-up period.

Purpose: We report a case of unilateral, focal, pigmented paravenous retinochoroidal atrophy (PPRCA). Case summary: A 46-year-old female visited our clinic in complaint of a vague problem with her right eye identified during a general medical examination. The visual acuity (without correction) of both eyes was 1.0. Slit-lamp examination of both eyes revealed no specific signs. Fundus examination of the right eye revealed focal, bony-spicule-shaped retinochoroidal atrophy with pigmentation along the course of the superior retinal vein. A fundus autofluorescence examination revealed principally hypofluorescence with some hyperfluorescence at the margin of the atrophic retinochoroidal lesion. Optical coherence tomography revealed mixed clumping and atrophy of the retinal pigment epithelium (RPE) layer and thinning of the choriocapillaris layer. Fluorescence angiography revealed a window defect and blockage at the site of the lesion (the fluorescent material did not enter the lesion). The site of the window defect was in correlation with the atrophic RPE region. The site of the blockage at lesion also matched with the site of the regional pigment clumping. No definite leakage was observed. Conclusions: To the best of our knowledge, this is the first case of unilateral focal PPRCA reported from Korea.

In the field of ophthalmology, many diagnostic instruments based on optical technology have been developed, such as refractometer, keratometer, corneal mapper, tonometer, fundus camera, slit lamp, laser scan ophthalmoscope and optical coherence tomography. Among them, the refractometer that is used for measuring the refractive power of the human eye has the long research history and various types have been developed. However the efforts to realize more accurate and precise measurement are still in progress. The wavefront analyzer commercialized in recent years is an excellent outcome of such efforts. In this paper, a brief account of the developmental history of various refractometers including the wavefront analyzer is summarized, and the underlying measurement principle is introduced in the view of optics. Finally, the technical issues that should be solved for getting better performance are discussed.
