Concordancia inter e intraobservador en la medida de los agujeros maculares por tomografía de coherencia óptica / Inter- and intra-observer agreement in the measurement of macular holes by optical coherence tomography

Antecedentes y objetivo El agujero macular de espesor completo (AMEC) es una lesión foveal causada por un defecto del espesor completo de la retina neurosensorial. En su diagnóstico y en la indicación de tratamiento quirúrgico se tiene en cuenta la medida del agujero según la herramienta proporcionada por la OCT. Dicha medida puede ser realizada por varios oftalmólogos a lo largo del seguimiento de un paciente. El objetivo de este estudio es averiguar si existe variabilidad intraindividual e interindividual en dichas mediciones. Material y métodos Revisión retrospectiva de imágenes de b-scans de OCT con diagnóstico de AMEC. Se realizaron mediciones del diámetro mínimo del AMEC mediante la herramienta manual disponible en el DRI-Triton (Topcon, Japón) en las escalas 1:1 y 1:2, en días diferentes, por 2 especialistas en retina y 2 residentes. Se compararon dichas mediciones para valorar la correspondencia interobservador e intraobservador Resultados Se analizan 34 imágenes. Para la variabilidad intraobservador se obtuvo un índice de correlación superior a 0,98 en todos los casos. Para la variabilidad interobservador, el coeficiente de correlación intraclase fue de 0,94 (IC del 95%, 0,91-0,97) para la escala 1:1, y de 0,94 (IC del 95%, 0.91-0,97) para la escala 1:2. Conclusiones Los valores del tamaño de los AMEC medidos por OCT son reproducibles entre oftalmólogos especialistas y residentes y son independientes de la escala de la imagen en la que se realice dicha medición (AU)

Background and objective A full-thickness macular hole (FTMH) is a foveal lesion caused by a defect in the full thickness of the neurosensory retina. Its diagnosis and the indication for surgical treatment take into account the measurement of the hole according to the tool provided by the OCT. This measurement can be performed by several ophthalmologists during the follow-up of a patient. The aim of this study is to find out whether there is intra-individual and inter-individual variability in these measurements. Material and methods Retrospective review of OCT b-scan images with a diagnosis of FTMH. Measurements of the minimum diameter of the FTMH were performed using the hand-held tool available on the DRI-Triton (Topcon, Japan) at 1:1 and 1:2 scales, on different days, by 2retina specialists and 2residents. These measurements were compared to assess inter-observer and intra-observer correspondence. Results Thirty-four images were analysed. For intra-observer variability, a correlation index higher than 0.98 was obtained in all cases. For inter-observer variability, the intra-class correlation coefficient was 0.94 (95% CI: 0.91-0.97) for the 1:1 scale, and 0.94 (95% CI: 0.91-0.97) for the 1:2 scale. Conclusions OCT-measured AMEC size values are reproducible between ophthalmic specialists and residents and are independent of the imaging scale at which the measurement is made (AU)

Reportar la formación de agujero macular durante la inyección intravítrea de perfluorocarbono líquido en la cirugía programada de desprendimiento de retina. Caso clínico Varón de 73 años con desprendimiento de retina regmatógeno superotemporal. Durante la inyección de perfluorocarbono líquido se produce un agujero macular de espesor completo con acumulación del perfluorocarbono en el espacio subretiniano. El líquido se extrajo a través del agujero macular. La tomografía de coherencia óptica confirmó un agujero macular de espesor total en el examen postoperatorio. Un mes después se repara con técnica de colgajo invertido de membrana limitante interna con resultado funcional satisfactorio. La inyección de perflurocarbono líquido intravítreo es electiva, facilita el drenaje del fluido subretiniano en los desprendimientos de retina. Algunas complicaciones han sido asociadas a su empleo, intraoperatorias y postoperatorias. Hasta el momento no ha sido reportado ningún caso de agujero macular completo producido durante la inyección intravítrea de perfluorocarbono (AU)

To describe a macular hole development during intravitreal injection of perfluorocarbon liquid used to repair a rhegmatogenous retinal detachment. Clinical case A 73-year-old man presented with superotemporal rhegmatogenous retinal detachment. During surgery, along the perflorocarbon liquid injection, a full thickness macular developed and perfluorocarbon was accumulated in subretinal space. Perfluorocarbon liquid was then extracted through the macular hole. Postoperatively, ocular coherence tomography confirmed the existence of a full-thickness macular hole. One month later, this macular hole was successfully treated with the use of an inverted internal limiting membrane flap.

Membrana de plasma rica en factores de crecimiento como tratamiento de agujero macular en una paciente vitrectomizada por desprendimiento de retina regmatógeno / Plasma rich in growth factors membrane as a macular hole treatment in a vitrectomized patient due to rhegmatogenous retinal detachment

La formación de un agujero macular tras una vitrectomía por desprendimiento de retina regmatógeno es una complicación rara. Aunque existen diferentes opciones quirúrgicas en el tratamiento de estos agujeros maculares con buenos resultados, se ha demostrado que el antecedente de un desprendimiento de retina con compromiso macular es el factor de riesgo más importante relacionado con la necesidad de múltiples intervenciones para el cierre de estos agujeros, por lo que debe prestarse especial atención al manejo de estos pacientes. Presentamos el caso de una paciente con desprendimiento de retina regmatógeno con compromiso macular que requirió tratamiento con cirugía de catarata, implante de lente intraocular y vitrectomía vía pars plana. Cuatro años después de la cirugía primaria presentó un agujero macular grande y fue tratada con membrana de plasma rica en factores de crecimiento con cierre del agujero macular y mejoría visual sin recidiva 12 meses después de la cirugía (AU)

The formation of a macular hole after vitrectomy due to rhegmatogenous retinal detachment is a rare complication. Although there are different surgical options in the treatment of these macular holes with favorable outcomes, it has been shown that the history of macula-off retinal detachment is the most important risk factor related to the need for multiple interventions to close these macular holes, therefore special attention should be paid in the management of these patients. We present the case of a patient with macula-off rhegmatogenous retinal detachment who required treatment with cataract surgery with intraocular lens implant and pars plana vitrectomy. Four years after the primary surgery, she presented a large macular hole, and was treated with membrane of plasm rich in growth factors with closure of the macular hole and visual improvement without recurrence 12 months after surgery (AU)

Técnica modificada del flap invertido superior con vitrectomía versus vitrectomía con pelado de membrana limitante interna para el desprendimiento de retina con agujero macular miópico / Modified superior inverted internal limiting membrane flap technique with vitrectomy versus vitrectomy with internal limiting membrane peeling for retinal detachment with myopic macular hole

Objetivo Evaluar la eficacia de la técnica del flap invertido superior de membrana limitante interna (MLI) modificada para el tratamiento del desprendimiento de retina (DR) por agujero macular (AM), comparada con el pelado clásico de la MLI. Materiales y métodos Análisis retrospectivo de 10 pacientes que requirieron vitrectomía pars plana por DR con AM. Se dividieron en dos grupos, según la técnica quirúrgica realizada: grupo del flap (5 pacientes) y de pelado de MLI (5 pacientes). Se comparó la agudeza visual mejor corregida (AVMC) pre y posquirúrgica, la resolución del DR, la tasa de cierre del AM y la restauración de las capas externas de la retina entre los grupos. Resultado La AVMC poscirugía mejoró en ambos grupos, sin diferencias significativas (p=0,9). La tasa de cierre del AM fue del 100% en el grupo del flap y del 80% del grupo de pelado de la MLI, sin diferencias significativas entre los grupos. La retina se reaplicó en el 100% de los casos en ambos grupos. Solo se restauraron las capas externas de la retina en 2 pacientes del grupo del flap invertido (40%) y en ninguno del grupo de pelado de la MLI (p=0,62). Conclusiones Las técnicas de pelado de MLI y del flap invertido superior modificada son útiles para el tratamiento del DR con agujero macular en ojos miopes (AU)

Purpose To evaluate the efficacy of the modified superior inverted internal limiting (ILM) membrane flap technique in retinal reattachment, macular hole closure and external retinal layers restoration in macular hole associated retinal detachment compared to ILM peeling. Methods Retrospective case series of 10 patients that required pars plana vitrectomy for retinal detachment with macular hole followed for more than 12months. Data from medical records were retrospectively collected and patients were divided into the superior inverted flap (5 patients) and ILM peeling group (5 patients). We compared best corrected visual acuity (BCVA) before and after surgery, retinal attachment, macular hole closure rate and external retinal layer restoration between groups. Results There were significant improvements in BCVA in both groups before and after surgery, with no differences between the two groups at 12months after surgery (P=.9). The macular hole closed in 100% of cases in the inverted flap group and 80% of the ILM peeling group with no significant differences between groups. The retina was reattached in 100% of cases in both groups. Only 2 patients in the inverted flap group (40%) had external retinal layer restoration and none in ILM peeling group (P=.62). Conclusions ILM peeling and superior inverted flap techniques are useful for treating retinal detachment with macular hole in myopic eyes (AU)

Resultados de la cirugía de agujero macular grande empleando distintas técnicas de interposición macular. Serie de 9 casos / Results of large macular hole surgery using different interposition techniques. A report on 9 cases

Objetivo Describir la restauración anatómica y funcional observada a largo plazo en pacientes intervenidos por agujero macular (AM) grande empleando distintas técnicas de interposición macular. Método Análisis retrospectivo de los resultados obtenidos en una serie de 9 pacientes sometidos a cirugía de AM grande (≥450μm) realizando 4 técnicas de interposición macular distintas: flap invertido de membrana limitante interna en 4 casos, plegado de membrana limitante interna en 2, injerto de membrana amniótica en 2 e injerto autógeno de cápsula anterior en uno. El tiempo de seguimiento medio fue de 11 meses. Anatómicamente las medidas de resultados exploradas fueron la restauración de las capas externas de la retina y el patrón de cierre macular. Funcionalmente se valoró la agudeza visual final y la calidad visual. Resultados La restauración de las capas externas fue parcial en 6 casos. La tasa de cierre macular fue del 100%, apreciándose un patrón incompleto en 4 casos. La agudeza visual mejoró en 7 pacientes, manteniéndose estable en 2. Tres casos mostraron un patrón de fijación excéntrico y/o metamorfopsias. Conclusiones El desarrollo de nuevas técnicas quirúrgicas ha incrementado la tasa de cierre macular en AM grandes. Sin embargo, la restauración anatómica y funcional sigue siendo impredecible. En este trabajo se logró el cierre macular en todos los pacientes y una mayor tasa de cierre completo empleando flap invertido de membrana limitante interna. La restauración de las capas externas fue más favorable en los grupos en los que se había empleado membrana limitante interna. La recuperación funcional fue independiente de la técnica empleada (AU)

Objective To describe the long-term anatomical and functional restoration observed in patients operated on for a large macular hole (MH) using different macular interposition techniques. Method Retrospective analysis of the results obtained in a series of 9 patients undergoing large MH surgery (≥450μm) performing 4 different macular interposition techniques: inverted internal limiting membrane flap in 4 cases, autotransplantation of internal limiting membrane in 2, amniotic membrane graft in 2, and autologous anterior capsule graft in one. The mean follow-up time was 11 months. Anatomically, the outcome measures explored were the restoration of the outer layers of the retina and the pattern of MH closure. The final visual acuity and visual quality were functionally assessed. Results The restoration of the outer layers was partial in 6 cases. The macular closure rate was 100%, showing an incomplete pattern in 4 cases. Visual acuity improved in 7 patients, remaining stable in 2. Three cases showed an eccentric fixation pattern and/or metamorphopsia. Conclusion The development of new surgical techniques has increased the rate of macular closure in large MHs. However, the anatomical and functional restoration remains unpredictable. In this work, macular closure was achieved in all patients and a higher rate of complete closure using inverted internal limiting membrane flap. The restoration of the outer layers was more favorable in the groups in which internal limiting membrane had been used. Functional recovery was independent of the technique used (AU)

Modified superior inverted internal limiting membrane flap technique with vitrectomy versus vitrectomy with internal limiting membrane peeling for retinal detachment with myopic macular hole.

PURPOSE: To evaluate the efficacy of the modified superior inverted internal limiting (ILM) membrane flap technique in retinal reattachment, macular hole closure and external retinal layers restoration in macular hole associated retinal detachment compared to ILM peeling. METHODS: Retrospective case series of 10 patients that required pars plana vitrectomy for retinal detachment with macular hole followed for more than 12 months. Data from medical records were retrospectively collected and patients were divided into the superior inverted flap (5 patients) and ILM peeling group (5 patients). We compared best corrected visual acuity (BCVA) before and after surgery, retinal attachment, macular hole closure rate and external retinal layer restoration between groups. RESULTS: There were significant improvements in BCVA in both groups before and after surgery, with no differences between the two groups at 12 months after surgery (p=0.9). The macular hole closed in 100% of cases in the inverted flap group and 80% of the ILM peeling group with no significant differences between groups. The retina was reattached in 100% of cases in both groups. Only 2 patients in the inverted flap group (40%) had external retinal layer restoration and none in ILM peeling group (p=0.62). CONCLUSIONS: ILM peeling and superior inverted flap techniques are useful for treating retinal detachment with macular hole in myopic eyes.

Atypical macular hole formation after Anti-VEGF therapy for neovascular age-related macular degeneration: Coincidence or consequence?

INTRODUCTION AND OBJECTIVES: Age-related macular degeneration (AMD) is the primary cause of blindness in developed countries, particularly in older adults. Anti-vascular endothelial growth factor (anti-VEGF) intravitreal injection is the current standard treatment for neovascular form of AMD. Studies reporting macular hole (MH) formation following anti-VEGF treatment are limited, and the exact pathogenesis is still under discussion. With the present study, we aim to analyse the clinical features of eyes developing MH after anti-VEGF therapy for neovascular AMD. MATERIALS AND METHODS: Patients were treated with intravitreal anti-VEGF agents for at least one year and stable for at least six months. Best-corrected visual acuity (BCVA) and optical coherence tomography findings were evaluated. RESULTS: Nineteen eyes of 18 patients were included in this study. Patients had an average age of 77.7 years at first visit and eight were female. The average number of injections before the MH formation was four. MH developed after a mean follow-up of 5.1 months after the last injection. Sixteen eyes had (84.2%) had choroidal neovascular membrane without any abnormal vitreomacular traction. Eleven eyes (57.8%) had retinal pigment epithelium detachment (PED), two (10.5%) had an epiretinal membrane (ERM), and one (5.2%) had retinal pigment epithelium (RPE) tear. The mean first and last BCVA was 1.07±0.48 LogMAR (0.3-1.8) and 1.16±0.38 logMAR (0.4-1.8), respectively. CONCLUSIONS: A macular hole can be observed in AMD patients receiving anti-VEGF therapy. Increased fibrovascular scar tissue due to subretinal fluid resolution, neovascular membrane contraction, and the presence of PED, RPE tear, and ERM may contribute to MH formation.

Formación atípica de agujero macular después de terapia Anti-VEGF para la degeneración macular asociada a la edad: ¿coincidencia o consecuencia? / Atypical macular hole formation after Anti-VEGF therapy for neovascular age-related macular degeneration: Coincidence or consequence?

Introducción y objetivos La degeneración macular asociada con la edad (DMAE) es la causa primaria de ceguera en los países desarrollados, especialmente en adultos mayores. Actualmente, la inyección intravítrea del factor de crecimiento endotelial vascular (VEGF) es el tratamiento estándar para la forma neovascular de la DMAE. Existen pocos estudios que informen sobre la creación de un agujero macular (AM) después de un tratamiento anti-VEGF, y la patogénesis exacta de AM permanece en debate. El presente estudio tiene por objetivo analizar las características clínicas de los ojos que desarrollan AM después de recibir terapia anti-VEGF para la DMAE neovascular. Materiales y métodos Los pacientes fueron tratados con agentes anti-VEGF intravítreos durante al menos un año, permaneciendo estables por, al menos, seis meses. Se evaluaron la mejor agudeza visual corregida (MAVC) y los hallazgos de tomografía de coherencia óptica. Resultado Se incluyeron en el estudio 19 ojos de 18 pacientes. La edad media de los mismos fue de 77,7 años en la primera visita. Ocho eran de sexo femenino. El número medio de inyecciones antes de la formación de un AM fue de cuatro. El AM se desarrolló después de un seguimiento medio de 5,1 meses desde la última inyección. Dieciséis ojos (84,2%) exhibieron membrana coroidal neovascular sin tracción vitreomacular anormal. Once ojos (57,8%) mostraron desprendimiento del epitelio pigmentario (DEP) de la retina, dos (10,5%) tuvieron membrana epirretinal (MER) y uno (5,2%) presentó desgarro del epitelio pigmentario de la retina (PER). La media de la MAVC fue de 1,07 ± 0,48 LogMAR (0,3 a 1,8) y 1,16 ± 0,38 logMAR (0,4 a 1,8), respectivamente (AU)

Hallazgos por tomografía de coherencia óptica en un caso de agujero macular tratado con trasplante autógeno de retina / Optical coherence tomography findings in a case of macular hole treated with an autologous retinal transplant

Se presenta un caso de una mujer de 56 años de edad con un agujero macular grande, de larga evolución, a quien se le realizó una cirugía de trasplante autógeno de retina neurosensorial. En el seguimiento con retinografías y tomografía de coherencia óptica de dominio espectral, destacó la presencia de edema del injerto con hiperreflectividad de las capas retinianas internas, en las primeras semanas. Después, se observaron puntos hiperreflectivos, predominantemente en las capas internas de la retina, manteniendo la continuidad de las capas externas y la presencia de un material de aspecto lanudo en la superficie del injerto. Al final del seguimiento hubo una integración completa del injerto en la zona receptora del agujero, con la correspondiente mejoría funcional (AU)

A case is presented of a 56-year-old female patient with a long-standing large macular hole who underwent autologous retina transplant surgery. Fundus images and spectral-domain optical coherence tomography images showed the presence of graft oedema with its corresponding hyper-reflectivity of the inner retinal layers in the first weeks of follow-up. Hyper-reflective dots later appeared mainly in the inner retinal layers. The integrity of the outer retinal layers and a woolly-looking material on the surface of the graft were observed. At the end of follow-up, the graft had integrated with the recipient tissue with functional improvement (AU)

A case is presented of a 56-year-old female patient with a long-standing large macular hole who underwent autologous retina transplant surgery. Fundus images and spectral-domain optical coherence tomography images showed the presence of graft oedema with its corresponding hyper-reflectivity of the inner retinal layers in the first weeks of follow-up. Hyper-reflective dots later appeared mainly in the inner retinal layers. The integrity of the outer retinal layers and a woolly-looking material on the surface of the graft were observed. At the end of follow-up, the graft had integrated with the recipient tissue with functional improvement.
