Retinosis pigmentaria sine pigmento. Inicio con edema macular / Retinitis pigmentosa sine pigmenti. Debut with macular oedema

CASO CLÍNICO: Mujer de 25 años que presenta metamorfopsia y disminución de agudeza visual en ojo izquierdo de un año de evolución. A la exploración se aprecia un edema macular quístico (EMQ) y atenuación vascular bilateral. Se describen las pruebas diagnósticas, así como el diagnóstico diferencial y la respuesta al tratamiento con inhibidores de anhidrasa carbónica. DISCUSIÓN: La retinosis pigmentaria sine pigmento es un subtipo de retinosis pigmentaria atípica, caracterizada por la ausencia de depósitos pigmentarios. La hemeralopía es más leve y la afectación campimétrica y electrorretinográfica es menor. El EMQ constituye una causa importante de pérdida de visión central, y responde al tratamiento con inhibidores de anhidrasa carbónica

CASE REPORT: A 25-year-old woman, with metamorphopsia in her left eye of one year onset. The examination revealed a bilateral cystoid macular oedema (CME) and vascular attenuation. We describe the diagnostic tests, as well as differential diagnosis and treatment response with carbonic anhydrase inhibitors. DISCUSSION: The retinitis pigmentosa sine pigment is a subtype of atypical retinitis pigmentosa characterised by the absence of pigment deposits. The night blindness is milder, and perimetric and electroretinographic impairment is lower. CME is an important cause of central vision loss, and responds to anhydrase carbonic inhibitors

[Retinal angiomatous proliferation not associated with age-related macular degeneration. Favourable outcome after photodynamic therapy]. / Proliferación angiomatosa retiniana no relacionada con degeneración macular asociada a la edad. Buena respuesta al tratamiento con terapia fotodinámica.

CASE: A 55-year-old male was diagnosed with exudative-hemorrhagic maculopathy, with no signs observed of drusen or pigmentary epithelium defects suggestive of age-related macular degeneration (ARMD). Fluorescein angiography (FA) and indocyanine green choroidal angiography (ICGA) showed retinal angiomatous proliferation (RAP). Afferent arteriole and retinal drainage venule connection was also observed. Treatment with a single Photodynamic Therapy provided an optimal outcome. DISCUSSION: RAP is a form of neovascular ARMD described in recent years; it consists of an angiomatous proliferation that originates from the retinal capillary system and extends posteriorly into the subretinal space. Our patient showed typical RAP findings without any sign of ARMD

[Optical coherence tomography of retinal pigment epithelial tears]. / Optical coherence tomography en desgarro del epitelio pigmentario retiniano.

CASE REPORTS: Three cases of pigmentary epithelial tears are described in this study. One of them was related to previous extrafoveal photocoagulation, whereas the other two were idiopathic. Fluorescein angiography (FA) and optical coherence tomography (OCT) were performed to confirm the clinical diagnosis. DISCUSSION: Few studies using OCT to assess pigmentary retinal epithelial (RPE) tears have been published in the world literature. The main findings of our study included hyper-reflectant line breaks, choroidal hyper-reflectance due to the lack of RPE and RPE double layering where it was folded. Images were frequently associated with RPE tears and neurosensorial retinal detachment.

[Pseudophakic cystoid macular edema. Assessment with optical coherence tomography]. / Edema macular quístico pseudofáquico. Detección mediante "optical coherence tomography".

PURPOSE: To determine the incidence of cystoid macular edema (CME) by means of clinical evaluation and subclinical assessment by means of ocular coherence tomography (OCT), and to compare the incidence between diabetic and non-diabetic groups of patients. METHODS: Prospective study of 260 consecutive cataract surgeries operated from September 2004 to March 2005. The procedures were performed by means of phacoemulsification plus intraocular acrylic lens implantation. Group A: 208 eyes of non-diabetic patients; Group B: 42 eyes of patients with diabetes and Group C: 10 eyes of diabetic patients with macular edema that received an intravitreal injection of triamcinolone at the end of surgery. Postoperative follow-up visits were performed 6 days (basal visit), 5 weeks and 12 weeks after surgery. Each visit included posterior pole biomicroscopy and OCT. RESULTS: Central macular thickness measured by OCT was significantly increased in group B compared with group A (241.6 versus 204.6 microm; p<0.001). No clinical evidence of CME was found in group A, although 4 eyes (1.92%) showed macular thickness equal to or greater than 43.74 microm (2 standard deviations of the basal value for group A). In group B, clinical evidence of CME was found in 6 eyes, with decreased visual acuities (14.2%). The differences between these groups were statistically significant (p<0.001). The 10 eyes that received an intravitreal injection of triamcinolone after the surgical procedure showed a mean decrease in central retinal thickness of 77 microm after 12 weeks postoperative. CONCLUSIONS: This study has shown a low incidence of clinical CME. OCT showed increased macular thickness in both groups of patients in a small percentage of cases, and significantly increased macular thickness in diabetic patients.

Terapia fotodinámica en neovascularización coroidea / Photodynamic therapy for treatment of choroidal neovaoscularization

Objetivo: Valorar la eficacia de la terapia fotodinámica (TFD) en el tratamiento de neovascularización subretiniana (NVSR) causada por DMAE (degeneración macular asociada a la edad) y miopía. Material y método: Se estudiaron 102 pacientes con neovascularización coroidea yuxta o subfoveolar tratados con TFD en los que se valoró: Agudeza visual (AV), examen oftalmoscópico y angiografía fluoresceínica. El retratamiento se realizó cuando fue necesario cada tres meses. Resultados: La etiología de la neovascularización coroidea fue: 75,5% por DMAE y 24,5% miópica. El tiempo de seguimiento medio fue de 15,94 meses (9-33). Un 88% de las NVSR eran angiográficamente clásicas en los miopes y un 40% en las DMAE. La supervivencia de la membrana resultó significativa en función del tipo de NVSR, presentando una mejor evolución en los pacientes miopes (p=0,0018). La AV mejoró en 48% de los pacientes miopes y en 28,6% de las DMAE. No se objetivaron complicaciones severas atribuibles al tratamiento. Conclusiones: La TFD es un tratamiento moderadamente efectivo y sin complicaciones para el tratamiento de la NVSR sub/yuxta foveolar(AU)

Purpose: To evaluate the efficacy of photodynamic therapy with photodynamic therapy (PDT) in the management of choroidal neovascularization (CNV) in age-related macular degeneration (AMD) and myopia. Methods: 102 eyes with subfoveal or yuxtafoveal CNV underwent visual acuity (VA) testing, ophthalmic examination, and fluorescein angiography. Retreatment of persistent CNV was done after three months. Results: CNV was caused by AMD in 75.5% of patients, pathologic myopia in 24.5%. Follow up ranged from 9 to 33 months (mean: 15.94 months). 88% of CNV caused by pathologic myopia was classic and 40% was in lesions caused by AMD. CNV survival was shorter in lesions caused by pathologic myopia with a significant difference (p=0.0018). VA improved in 48% of lesions caused by pathologic myopia and in 28.6% of lesions caused by AMD. We did not observe any severe complication caused by PDT. Conclusion: PDT is a moderately effective treatment without complications in treating subfoveal CNV(AU)

[Idiopathic polypoidal choroidal vasculopathy]. / Vasculopatía coroidea polipoidal idiopática.

PURPOSE: To evaluate the incidence, clinical features and evolution of polypoidal choroidal vasculopathy (PCV) in our population. METHODS: Retrospective study of patients diagnosed with exudative and/or hemorrhagic maculopathy including age-related macular degeneration in the last two years and who have undergone a complete ophthalmologic exploration and videoangiography with fluorescein and indocyanine green. RESULTS: 250 patients were included in the study, 8 patients (3.2%) had clinical and angiographic criteria of PCV. The mean age was 68 years-old, 62.5% were men and 85.7% were caucasian. Ninety percent of cases presented clinically as a predominantly hemorrhagic macular detachment. The initial clinical diagnosis before indocyanine green angiography was exudative age-related macular degeneration in 90% of cases. The mean visual acuity was 0.2 at baseline and after follow-up. Laser treatment was performed in 4 eyes, achieving good anatomic and visual acuity results in 2 of them; both eyes of one patient were treated by photodynamic therapy with poor angiographic and functional outcome. CONCLUSIONS: Polypoidal choroidal vasculopathy is a clinical entity which is relatively frequent among patients previously diagnosed with exudative maculopathy. Indocyanine green angiography increases the number of correct diagnoses. Treatment must be individualized depending on the location of the lesions and the severity of the disease.

[Serpiginous choroiditis: clinical course and treatment]. / Coroiditis serpiginosa: evolución clínica y tratamiento.

PURPOSE: To evaluate the clinical evolution and treatment of serpiginous choroiditis in 11 diagnosed patients. METHODS: Retrospective study of 11 cases diagnosed with serpiginous choroiditis in our area, from 1980 to the present. We analyzed age at onset of symptoms, systemic diseases, ophthalmological symptoms at presentation, the location of lesions, initial and final visual acuity, recurrences, treatment régime and development of subretinal neovascularization. A complete ophthalmological examination and fluorescein angiograms were performed in all of them. RESULTS: The mean period of follow-up was 4 years. Average age was 56 years, predominantly in men (10/1). Five patients had known ischemic cardiopathy and systemic hypertension, one patient underwent a kidney transplant. All of them were treated with oral prednisone (1-1.5 mg/kg/daily) in the active stages. Three patients received triple therapy (prednisone, cyclosporine and azathioprine) that did not prevent the recurrences. Five patients developed a subretinal neovascularization, bilateral in three of them. CONCLUSIONS: The serpiginous choroiditis is a rare entity and the visual outcome prognosis is determined by the macular involvement. Men are predominantly affected in our series and corticosteroid treatment is effective in acute inflammatory episodes. Recurrences could not be prevented by triple therapy with immunosuppressive agents in our three patients.

PURPOSE: To evaluate the efficacy of photodynamic therapy with photodynamic therapy (PDT) in the management of choroidal neovascularization (CNV) in age-related macular degeneration (AMD) and myopia. METHODS: 102 eyes with subfoveal or yuxtafoveal CNV underwent visual acuity (VA) testing, ophthalmic examination, and fluorescein angiography. Retreatment of persistent CNV was done after three months. RESULTS: CNV was caused by AMD in 75.5% of patients, pathologic myopia in 24.5%. Follow up ranged from 9 to 33 months (mean: 15.94 months). 88% of CNV caused by pathologic myopia was classic and 40% was in lesions caused by AMD. CNV survival was shorter in lesions caused by pathologic myopia with a significant difference (p=0.0018). VA improved in 48% of lesions caused by pathologic myopia and in 28.6% of lesions caused by AMD. We did not observe any severe complication caused by PDT. CONCLUSION: PDT is a moderately effective treatment without complications in treating subfoveal CNV.

[Photodynamic therapy for choroidal neovascularization not caused by age related macular degeneration or pathologic myopia]. / Terapia fotodinámica en membrana neovascular subretiniana no relacionada con degeneración macular asociada a la edad o miopía patológica.

PURPOSE: To assess the effects of photodynamic therapy (PDT) with verteporfin on visual acuity (VA) and fluorescein angiography, in patients with subfoveal choroidal neovascularization (CNV) not secondary to age related macular degeneration (AMD) or pathologic myopia. METHODS: 113 eyes from 104 patients underwent PDT due to subfoveal CNV from July 2001 to June 2002. In this study only those patients with CNV not related to AMD or pathologic myopia were included. Fluorescein angiography and visual acuity were evaluated. RESULTS: 9 eyes from 8 patients (8.03%) showed distinct causes of CNV: 3 were idiopathic cases, 1 suffered angioid streaks, 1 was secondary to laser photocoagulation due to diabetic retinopathy, 2 had polypoidal choroidal vasculopathy and 2 central serous choroiditis. Regarding VA results, 77.7% improved or mantained the previous VA. Angiography resolution was observed in 55.5% of the cases (80% with just one PDT session). Average follow up was 10.5 months. Systemic or local complications were not observed. CONCLUSION: PDT may be useful in the treatment of different types of CNV due to causes other than AMD or high myopia.

[Dynamic angiography in age related macular degeneration]. / Angiografía dinámica: diagnóstico y tratamiento en la degeneración macular asociada a la edad.

PURPOSE: To evaluate the utility of dynamic angiography with fluorescein and indocyanine green with scanning laser ophthalmoscope (SLO) in exudative age-related macular degeneration. METHOD: We retrospectively studied 95 patients with exudative age-related macular degeneration (ARMD) between April 98 and April 01. RESULTS: We studied 102 eyes of 95 patients with ARMD. Mean age was 75.3 years with a mean follow-up time of 16.8 months. We found an occult or mixed angiographic membrane pattern with fluorescein angiography in 85 eyes (83.3%). Angiography with indocyanine green showed choroidal neovascular membranes in 94 of 102 eyes (92.1%). The most frequent location found was sub-foveal (53.2%). Laser photocoagulation was used in 55 eyes and photodynamic therapy in 5 eyes. In 17 eyes laser treatment failed to close the membrane. CONCLUSION: Dynamic angiography with fluorescein or indocyanine green allowed neovascular membrane identification in more than 90% of the cases of ARMD. Successful treatment was achieved in 42% of cases.

UNLABELLED: PURPOSE/MATERIAL AND METHOD: Cyanoacrylate tissue adhesive is indicated when a small corneal perforation is present. We report the case of a 23 year-old man who was attacked being thrown cyanoacrylate to both of his eyes. RESULTS/CONCLUSION: Wound healing has been laborious, however performed with low morbidity. This case is reported for being a bilateral injury and after finding no precedented cases in the literature.

Agresión con cianocrilato / Ocular cyanoacrylate injury

Objetivo/Método: El cianocrilato se utiliza en oftalmología para el tratamiento de pequeñas perforaciones corneales. Presentamos el caso de un varón de 23 años que fue agredido con el lanzamiento sobre ambos ojos de un pegamento cuyo componente fundamental es el cianocrilato. Resultados/Conclusiones: A pesar de la aparatosidad de la situación y la laboriosidad de la extracción de las placas, la morbilidad fue baja. Sin embargo, ya que las referencias bibliográficas en oftalmología sólo se refieren a las instilaciones accidentales y a la rareza de bilateralidad del caso, aportamos este caso clínico junto con una revisión de la bibliografía (AU)
