We report four cases in which a pericardium (Tutoplast(R)) plug was used to repair a corneoscleral fistula after Ahmed Glaucoma Valve (AGV) explantation. In four cases in which the AGV tube had been exposed, AGV explantation was performed using a pericardium (Tutoplast(R)) plug to seal the defect previously occupied by the tube. After debridement of the fistula, a piece of processed pericardium (Tutoplast(R)), measured 1 mm in width, was plugged into the fistula and secured with two interrupted 10-0 nylon sutures. To control intraocular pressure, a new AGV was implanted elsewhere in case 1, phaco-trabeculectomy was performed concurrently in case 2, cyclophotocoagulation was performed postoperatively in case 3 and anti-glaucomatous medication was added in case 4. No complication related to the fistula developed at the latest follow-up (range: 12~26 months). The pericardium (Tutoplast(R)) plug seems to be an effective method in the repair of corneoscleral fistulas resulting from explantation of glaucoma drainage implants.

3.Neovascular Glaucoma Due to Branch Retinal Vein Occlusion Combined with Branch Retinal Artery Occlusion.
Korean Journal of Ophthalmology 2013;27(1):64-67
Branch retinal artery occlusion (BRAO) and branch retinal vein occlusion (BRVO) rarely cause neovascular glaucoma (NVG). A 58-year-old woman with hypertension and type 2 diabetic mellitus complained of progressive visual loss in her right eye for the previous 3 months. At initial examination, visual acuity was 20 / 63 in the right eye. Angle neovascularization was observed and the intraocular pressure (IOP) was 30 mmHg in her right eye. Fundus examination and fluorescein angiography showed BRAO combined with BRVO. We immediately injected intravitreal and intracameral bevacizumab in her right eye. The next day, we performed scatter photocoagulation in the nonperfusion area. One month later, visual acuity was 20 / 20 in her right eye and the IOP was 17 mmHg with one topical antiglaucoma agent. The neovascularization had regressed completely. We report a case of unilateral NVG which was caused by BRAO with concomitant BRVO and advise close ophthalmic examination of the iris and angle in BRVO with BRAO.

A 60-year-old diabetic patient transferred to our retina clinic for a regular follow-up for diabetic retinopathy. He had uneventful cataract surgery at the time of pars plana vitrectomy in the right eye due to diabetic retinopathy at a private ophthalmologic hospital. Six months after the surgery, neovascular glaucoma with hyphema developed in the right eye and an Ahmed valve was implanted at our hospital. Ten months after cataract surgery, we found opacification of the intraocular lens (IOL) which was causing significant visual disturbance. At the time, the best corrected visual acuity (BCVA) in the right eye was hand motion. The IOL was explanted 45 months after the operation. Five months after explantation, the BCVA was 0.06. Unfortunately, pathologic analysis was not performed. Patient-related factors such as an anterior chamber reaction caused by hyphema might have been responsible for the opacification. To our knowledge, there are no previous reports of opacification of the Akreos Adapt IOL.

We report on a case of cholesterosis bulbi concurrent with secondary glaucoma. A 36-year-old man, with a history of long-standing retinal detachment in his right eye after the irrigation and aspiration of a congenital cataract, presented with a clinical picture of elevated intraocular pressure and ocular pain. Upon slit-lamp examination, we found a ciliary injection and a pseudohypopyon of polychromatic crystals. Gonioscopic examination revealed a large amount of crystals deposited on the trabecular meshwork and mild rubeosis iridis, but the neovascularization of the angle could not be clearly confirmed due to the presence of so many crystals. Pars plana vitrectomy was performed to remove clusters of crystals and bevacizumab was injected intravitreally to treat iris neovascularization. Aqueous aspirate was examined by light microscopy and the typical highly refringent cholesterol crystals were identified. Intraocular pressure returned to a normal level after the bevacizumab injection, although severe cholesterosis was still evident in the anterior chamber. To our knowledge, this would be the first Korean case of cholesterosis bulbi combined with chronic retinal detachment and presumed neovascular glaucoma, which was treated by pars plana vitrectomy and intravitreal bevacizumab injection.

6.Neovascular Glaucoma Following Stereotactic Radiosurgery for an Optic Nerve Glioma: A Case Report.

Korean Journal of Ophthalmology 2010;24(4):252-255
A 13-year-old girl with a right intraorbital optic nerve glioma (ONG) was referred to our glaucoma clinic because of uncontrolled intraocular pressure (IOP) in her right eye. The IOP reached as high as 80 mmHg. Several months earlier, she had undergone stereotactic image-guided robotic radiosurgery using the CyberKnife for her ONG; the mass had become smaller after treatment. Her visual acuity was no light perception. Slit lamp examination revealed rubeosis iridis, a swollen pale optic disc, and vitreous hemorrhage. After medical treatment, the IOP decreased to 34 mmHg, and no pain was reported. Although the mass effect of an ONG can cause neovascular glaucoma (NVG), this case shows that stereotactic radiosurgery may also cause NVG, even after reducing the mass of the tumor. Patients who undergo radiosurgery targeting the periocular area should be followed carefully for complications.

We report three cases of neovascular glaucoma secondary to central retinal artery occlusion (CRAO) which were effectively managed with intravitreal bevacizumab (IVB) followed by panretinal photocoagulation (PRP). Neovascular glaucoma without peripheral anterior synechiae developed between one and five weeks following CRAO onset. All patients received 0.75 mg (0.03 ml) IVB. In all patients, complete regression of the iris and anterior chamber angle neovascularization was confirmed within one week. PRP was applied two weeks after the injection. The follow-up period was four to seven months (average, five months). Intraocular pressure was controlled in all patients using topical antiglaucoma medications alone. However, one patient experienced a recurrence of neovascularization three months after the initial combination treatment. This patient received another IVB injection and additional PRP, and the recurrent neovascularization resolved. There were no local or systemic adverse events in any patients. Therefore, intravitreal bevacizumab may be an effective adjunct in the treatment of neovascular glaucoma associated with CRAO.

This prospective observational case series study included 6 eyes of 6 consecutive glaucomatous patients. Each patient underwent trabeculectomy with mitomycin C, and received a 1.25 mg of subconjunctival bevacizumab injection at completion of the trabeculectomy. Study eyes included two with neovascular glaucoma, three with uveitic glaucoma, and one with secondary glaucoma following vitrectomy. All eyes had undergone failed glaucoma laser/surgical treatment or an intraocular surgical procedure. Intraocular pressure (IOP) at the following postoperative visits: preoperative, 1 week, 1 month, 2 months, 3 months, and 6 months, was measured. We also evaluated postoperative bleb findings and complications. IOP measured at each visit was 37.5+/-14.4 mmHg, 6.2+/-3.4 mmHg, 8.3+/-7.2 mmHg, 12.0+/-4.4 mmHg, 10.8+/-3.1 mmHg, and 12.2+/-3.3 mmHg, respectively, for each visit. All eyes had functioning blebs with normal IOP at postoperative 6 months with no additional IOP-lowering medication.

9.Progression of Impending Central Retinal Vein Occlusion to the Ischemic Variant Following Intravitreal Bevacizumab.
Korean Journal of Ophthalmology 2010;24(3):179-181
A 60-year-old woman who had experienced two episodes of amaurosis fugax in her right eye presented with vision loss. Two weeks earlier, at a private clinic, she was diagnosed with impending central retinal vein occlusion (CRVO) of the right eye and received an intravitreal injection of bevacizumab. Two weeks after this injection she was diagnosed with ischemic CRVO. At 11-weeks post-presentation, extremely ischemic features were observed with fluorescein angiographic findings of severe vascular attenuation and extensive retinal capillary obliteration. At 22-weeks post-presentation she was diagnosed with neovascular glaucoma; she experienced no visual improvement over the following several months.

We report a case of ocular ischemic syndrome accompanied by neovascular glaucoma that was successfully treated with Bevacizumab. A 70-year-old male patient diagnosed with neovascular glaucoma of the left eye 3-4 years prior complained of continuous left eye pain and declining visual acuity despite receiving the latest treatment methods. At the time of admission the patient had no light perception in the left eye and his intraocular pressure was 30 mmHg. Anterior segment and fundus examinations revealed neovascularization of the iris and stenosis of the retinal vessel. Hypofluorescence of the choroid and retinal vessels was observed on fluorescence fundus angiography. Left internal carotid artery stenosis was observed on a brain MRI. Despite being treated with eye solution and oral medication, intraocular pressure was not controlled. After 7 days, we performed an intravitreal Bevacizumab 1.25 mg/0.05mL injection. One day after the intravitreal Bevacizumab injection, the neovascularization had nearly regressed and intraocular pressure was 30 mmHg. Intravitreal Bevacizumab injection produced regression of neovascularization and proved effective for treatment of neovascular glaucoma in this case of ocular ischemic syndrome.
