A case of potassium iodate toxicity in a 22-year-old man was reported. After taking a solution of highly concentrated potassium iodate, the patient developed nausea, vomiting, diarrhea and blurred vision. The visual acuity was hand motion in both eyes. The funduscopic examination showed retinal edema with subsequent pigmentary change at the macula and retinal pigment clumping resembling retinitis pigmentosa. The fundus fluorescein angiography and electrophysiologic studies showed degenerative changes of the retinal pigment epithelium and photoreceptor cells.

The Laurence-Moon-Biedl syndrome is characterized by features of familial occurrence, retinitis pigmentosa, obesity, polydactyly, hypogenitalism and mental retardation. Recently, several reports have suggested renal abnormalities as an additional cardinal feature of the syndrome. We present two cases of this syndrome from two different families. The first case was an obese eight-year-old girl with poor vision and signs of mental retardation beginning at four months of age. An intravenous urogram showed dilatation of the minor calyces of both kidneys. Genital agenesis and typical retinitis pigmentosa on fundal examination all supported the diagnosis of Laurence-Moon-Biedl syndrome. The patient's father and grandmother also had symptoms of poor vision, mental retardation and obesity. The second case was an obese 14-year-old girl with blurred vision and severe mental retardation noticed at two to three months of age. Fundi showed typical retinitis pigmentosa. She also had genital agenesis but no significant family history.

A 57-year-old man with retinitis pigmentosa and subcapsular cataract had phacoemulsification with a continuous curvilinear capsulorhexis and implantation of a poly(methyl methacrylate) intraocular lens. Six months later, the patient presented with blurred vision and severe anterior capsule fibrosis which led to complete posterior chamber lens encapsulation.

There have been no reports describing polypoidal choroidal vasculopathy (PCV) in eyes with retinitis pigmentosa (RP). A 63-year-old woman who had been diagnosed as having RP was referred to us because of sudden onset of blurred vision in her right eye. Funduscopic examination revealed retinal findings typical of RP in both eyes. The macular area of the right fundus showed polypoidal lesions with massive hemorrhages. Fluorescein angiography and indocyanine green angiography showed multiple polypoidal lesions. Optical coherence tomography showed a large hemorrhagic retinal pigment epithelial (RPE) detachment and polypoidal lesions. The PCV subsided after three applications of anti-vascular endothelial growth factor (VEGF) therapy and a single application of photodynamic therapy, but "mottled lesions" with hyper- and hypofluorescence appeared temporal to the macula after disappearance of hemorrhage. We present a case of PCV in an eye with RP. Further studies are necessary to clarify whether anti-VEGF therapies could affect RPE status in eyes with RP.

Choroidal neovascularization secondary to retinitis pigmentosa is rarely observed in clinical practice. The present study describes a case of atypical retinitis pigmentosa, crystalline retinal pigmentary degeneration, complicated by choroidal neovascularization (CNV) in a 26-year-old man presenting with blurred vision in the right eye. Heidelberg multimodality imaging was performed to achieve a confirmed diagnosis. Bevacizumab was injected once intravitreally. The 3-month follow-up included visualization of the lesion's regression with spectral domain optical coherence tomography (SD-OCT). However, at 3 months after the injection, the CNV reoccurred. To the best of our knowledge, this is the first time that a case of CNV secondary to retinitis pigmentosa, in which the diagnosis was confirmed via multimodality imaging and the therapeutic efficacy was evaluated by SD-OCT, has been reported in China.
