Ocular ischemic syndrome is a chronic ischemic eye disease including a series of ischemic ocular and brain syndromes caused by carotid artery occlusion or stenosis. Because of the different degrees of ischemia, clinical manifestations of ocular ischemic syndrome are diverse, and it is difficult to diagnose in the initial stage. The main strategy to treat ocular ischemic syndrome is elimination of carotid stenosis. We presented a patient who recovered dramatically after carotid artery stenting. The pre-stenting arm-retinal circulation time of the patient’s left eye was prolonged, and a large amount of microaneurysm appeared at the posterior polar and mid-peripheral aspects of the left retina. The post-stenting arm-retinal circulation time of the left eye decreased to 16.3 seconds, and the microaneurysm almost disappeared.

2.Cryotherapy for retinopathy of incontinentia pigmenti.
Korean Journal of Ophthalmology 1991;5(1):47-50
A case with typical skin lesions of incontinentia pigmeti showed progressing retinal vascular abnormalities. So cryotherapy was done on avascular peripheral retina, and retinal vascular changes ceased. We propose that cryotherapy may be a good treatment method for progressing retinal vascular lesions of incontinentia pigmenti.

4.Early surgical management in bilateral acute retinal necrosis.
Korean Journal of Ophthalmology 1990;4(1):46-49
One patient with bilateral acute retinal necrosis underwent encircling scleral buckle, vitrectomy, and intravitreal acyclovir on both eyes. This procedure was performed on the right eye while the retina was attached. The retina of the right eye was reattached by performing fluid-gas exchange and modified panretinal photocoagulation when the retina subsequently detached. Soon after the development of retinal detachment in the left eye, the above surgical procedures were performed on the left eye, and the retina was successfully reattached.Bilateral acute retinal necrosis with significant vitreous opacification, which is a devastating ocular disease causing possible blindness in both eyes, requires more aggressive, early surgical management.

In the process of closing scleral wounds caused by various conditions, incarceration of conjunctiva, Tenon's capsule, or vitreous in the wound can occur unexpectedly. We created such conditions experimentally in order to discover their intraocular complications. The experimental materials consisted of 12 albino rabbits (24 eyes) divided into two groups (Groups I & II). Vitrectomy was performed in the Group I rabbits (12 eyes) but not in the Group II rabbits (12 eyes). Flaps of conjunctiva and Tenon's capsule were made and inserted into the vitreous cavity through the sclerotomy site, which was soon closed. Fundal examination of the rabbits was carried out using an indirect ophthalmoscope at intervals after the procedure; first at 3 days, then at 1, 3, and 6 weeks, and then at 3 months and 6 months, respectively. Enucleation of the rabbits' eyes 4 from two different rabbits at each of these intervals was carried out, and the extracted eyes were examined under a light microscope at each interval. The results are summarized as follows: 1. All rabbit eyes studied showed intraocular fibrovascular proliferation. 2. The extent of tissue proliferation, which was proportional to the amount of vitreous hemorrhage, was greater in Group II than in Group I. 3. The proliferated tissue developed to "band" by three weeks postexperiment, after which it gradually regressed. 4. The fibrovascular band was made of fibroblasts, stromal matrix, and capillaries.

OBJECTIVETo explore the diagnosis, classification, and management of uveal effusion syndrome (UES).
METHODSThe clinical data of 10 patients diagnosed with UES in our hospital between 1990-2010 were extracted from hospital records and analyzed, including ophthalmologic examination, ophthalmologic ultrasonography, ultrasound biomicroscopy (UBM), fundus fluorescence angiography (FFA), indocyanine green (ICG) angiography, surgical procedures, and outcomes.
RESULTSThe fundus examination of all impacted eyes showed bullous retinal detachment shifting with head position, confirmed by ultrasonography revealing retinal and choroidal detachment. UBM showed annular peripheral ciliochoroidal detachment in all cases. FFA was performed in 5 patients and revealed leopard spots without leakage from choroid into subretinal space. ICG angiograpy was performed in 3 patients and demonstrated diffused granular marked hyperfluorescence in the choroidal fluorescence in the very early phase, which increased with time and persisted until the late phase. Four eyes of 2 patients underwent full-thickness sclerectomies and 1 eye of 1 patient underwent subscleral sclerectomy, all of whom achieved reattachment of the retina without recurrence during 1-year follow-up.
CONCLUSIONSComprehensive preoperative evaluation, including ophthalmologic ultrasonography, computed tomography, and magnetic resonance imaging, is crucial for accurate classification of UES and selection of proper management strategy. Surgical treatment can achieve optimal clinical outcomes for type 1 and type 2 UES.

INTRODUCTIONThe aim of this review was to describe the use of optical coherence tomography (OCT) in the diagnosis and management of retinal angiomatous proliferation (RAP) in patients with age-related macular degeneration (AMD).
MATERIALS AND METHODSWe reviewed the tomographic characteristics of the eyes affected by RAP seen at our institution and imaged by OCT. Some eyes with RAP were also studied with OCT prior to and after laser treatment to determine the tomographic changes following laser photocoagulation.
RESULTSIn this preliminary report, OCT showed a typical pattern of structural changes in RAP: increased foveal thickness, cystoid macular oedema (CME) consisting of large central cysts and smaller cystoid spaces located mainly in the outer retinal layers, serous retinal detachment and a highly reflective intraretinal mass overlying a highly or moderately elevated retinal pigment epithelium (RPE). This mass corresponded to the hot spot observed on ICG angiography. After successful laser photocoagulation, significant decrease in foveal thickness, complete resolution of CME and retinal detachment with thinning of the neurosensory retina overlying the treated area could be observed.
CONCLUSIONSOCT appears to be useful in evaluating and documenting RAP in AMD patients both before and after laser photocoagulation. Longitudinal studies are required to determine its exact place and utility in clinical practice.

Examination of a 36-year-old man with naked visual acuity of 20/20 revealed a floating, conspicuous cyst of Cysticercus cellulosae in the vitreous cavity of the right eye. A vitreous traction band from the vitreous base and the optic disc was connected to the lodging bulb of the cyst. In the superonasal area, an ovoid retinal break surrounded by a white retinal lesion with two elliptical retinal hemorrhages was found, and this seems to be the previous lodging site of the cyst. A pars plana vitrectomy was performed to remove the parasite, and laser photocoagulation was carried out around the retinal break. Four months after the operation, the patient was satisfied with naked visual acuity of 25/20 without any complication in the affected eye.

10.Results of vitreous surgery for posterior complications of chronic uveitis.
Korean Journal of Ophthalmology 1994;8(1):20-25
To determine surgical results and predictive factors of final visual acuity, a total of 30 eyes in 30 uveitis patients who underwent vitreous surgery including pars plana vitrectomy were followed for at least 6 months and various preoperative factors and postoperative results were analyzed. Our surgical indications were vitreous opacity, traction retinal detachment, combined rhegmatogenous-traction detachment. Preoperatively detached retina was finally reattached in 15 (83.3%) of 18 eyes. Final visual acuity improved in 19 (63.3%) of 30 eyes, but decreased in 3 eyes compared with the initial acuity. Cystoid macular edema was the main cause of poor visual acuity after surgery. Eyes with good final visual acuity showed relatively normal electroretinograms before surgery, but the relationship between them was not statistically significant. Duration of postoperative inflammation affected final visual acuity significantly. These results suggest that chronic uveitis patients with vitreoretinal complications can be managed by vitreous surgery with good anatomic and functional results.
