An 18-year-old Japanese boy with optic disk drusen associated with left central retinal artery occlusion was reported. Transient central blurred vision, possibly caused by central retinal artery spasm, was noticed as an initial symptom of optic disk drusen in the left eye. Prolonged and repeated spasm might have given rise to a central retinal artery occlusion followed by neovascular glaucoma. The relationship between drusen in the disk and intrapapillary circulation disturbances was discussed.

Clinical picture of isolated retinal vasculitis (IRV) in 43 patients (25 men and 18 women) aged 22-42 years is analyzed. IRV was bilateral in 88.4% cases and involved the veins. Two forms of disease were distinguished: peripheral (in 75%) and central-peripheral (25%). Both forms were characterized by a high hemorrhagic activity, occlusion of vessels, ischemic zones and neovascularization of the retina and optic disk, but these signs were more frequent in central peripheral form of IRV. IRV is a grave disease leading to poor vision or blindness in 18% cases. The onset is poorly manifest with floating spots and blurred vision; the main symptom is vitreous hemorrhage. Visual acuity was significantly decreased in patients with occlusive IRV in comparison with those without occlusions (0.32 +/- 0.37 vs. 0.77 +/- 0.28). The earliest changes can be detected mainly in the peripheral parts of the retina. This necessitates special attention of ophthalmologist to seemingly negligible complaints of patients and thorough examination of the fundus oculi, particularly of its peripheral sections, which can be performed only on condition of adequate mydriasis. Only timely diagnosis and early pathogenetic therapy can decrease the probability of such complications as hemophthalmos, retinal neovascularization, detachment of retina, and neovascular glaucoma, and prevent disability.

Reported herein is a case of 62-year-old man who complained of blurred vision and ocular pain in his right eye. The patient was diagnosed with choroidal melanoma complicated by neovascular glaucoma (NVG) and total retinal detachment, and he underwent enucleation of the eye. The isolated tumor was 2.5 x 2.5 cm in size. It was accompanied by intratumoral calcification, and consisted of epithelioid and spindle melanoma cells. There were a variety of microvessels in the stroma of the iris. The expression of thymidine phosphorylase (dThdPase), an angiogenic factor, was examined immunohistochemically. Cytoplasmic immunoreactivity for dThdPase was more prominent in the epithelioid cells than in spindle tumor cells. Another case of choroidal melanoma without NVG had less marked immunoreactivity. These results suggest that the production of dThdPase by melanoma cells correlates with the pathogenesis of NVG.

A 12-year-old girl with neurofibromatosis type 1 was referred for pain and blurred vision in her right eye for the past 2 weeks. Neovascular glaucoma associated with peripheral retinal ischemia was diagnosed and she was treated with retinal photocoagulation after intravitreal bevacizumab injection and trabeculectomy.

We report the case of a 66-year-old Japanese man who developed neovascular glaucoma secondary to Purtscher's retinopathy following a head injury. The patient presented at our hospital with blurred vision and a visual field abnormality in his left eye 1 month after suffering from a head injury. Upon initial presentation, his best-corrected visual acuity on a decimal chart was 1.5 oculus dexter and 0.6 oculus sinister. The intraocular pressure (IOP) was 12 mmHg in both eyes. Fundus examination of the left eye revealed multiple white lesions in the posterior pole. Optical coherence tomography demonstrated retinal edema, particularly in the inner retina. On the basis of these findings, a diagnosis of Purtscher's retinopathy was made. One month after the initial examination, the visual acuity in the left eye deteriorated to 0.01 in decimal chart, and the IOP increased to 37 mmHg. Gonioscopy showed angle neovascularization. The patient received an intravitreal bevacizumab injection and panretinal photocoagulation. Subsequently, the IOP normalized and the angle neovascularization regressed.

A 79-year-old man who had been diagnosed with small cell lung carcinoma (SCLC) complained of right ocular pain and blurred vision. His right intraocular pressure (IOP) was 30 mm Hg, and anterior chamber cells and multiple grayish white iris masses associated with peripheral anterior synechia (PAS) and neovascularization of the right iris were observed. We presumed that the iris masses were iris metastasis of SCLC. Despite therapy with topical eye drops and oral acetazolamide, the IOP was poorly controlled, so we injected intravitreal bevacizumab into his right eye for neovascular glaucoma. Neovascular glaucoma disappeared rapidly, but the IOP did not improve because of total PAS. To our knowledge, there is only one report of the use of intravitreal bevacizumab for SCLC metastasis in that eye and they reported that intravitreal injection resulted in successful short-term regression of presumed iris metastasis and improved control of secondary neovascular glaucoma, and the case had over one-half PAS. The previous report and our results suggest that secondary neovascular glaucoma with iris metastasis may be controlled by early intravitreal bevacizumab injection.
