Uso de implantes intravitreos de dexametasona en el tratamiento del edema macular secundario a oclusiones venosas retinianas
257 p.Presentamos una tesis por compendio en la que resumimos las publicaciones realizadas desde diciembre de 2012 hasta junio de 2021 en relación con el uso de los implantes intravítreos de dexametasona para el tratamiento del edema macular secundario a oclusiones venosas de la retina (OVR) en pacientes de la Organización Sanitaria Integrada Araba de Vitoria-Gasteiz. Los objetivos generales de la tesis se centran en cuatro aspectos: determinar las características epidemiológicas de los pacientes con edema macular secundario a OVR tratados con inyecciones intravítreas de dexametasona en nuestra Unidad, evaluar la efectividad funcional y anatómica a corto plazo del fármaco, analizando la variación en la agudeza visual y la variación en el grosor y volumen macular centrales, analizar la seguridad a corto plazo del fármaco y describir la eficacia y seguridad a largo plazo. Los resultados han sido expuestos en siete trabajos publicados en revistas de oftalmología del cuartil 1 y 2. Las conclusiones de estos estudios demuestran la efectividad del implante intravítreo de dexametasona a corto y largo plazo, su seguridad a corto y largo plazo pese a que describimos efectos adversos nuevos y se describen nuevos factores de riesgo asociados a la variación de la agudeza visual y grosor y volumen macular centrales
Dabrafenib for cutaneous melanoma infiltrating the vitreous: regression of metastasis and occurrence of uveitis as a secondary effect
Intraocular metastasis of cutaneous melanoma is extremely infrequent. This typically occurs in advanced metastatic disease and has a poor survival prognosis. The most frequent reported treatment is radiotherapy. BRAF inhibitors are new, orally administered and very effective drugs used for metastatic cutaneous melanoma. Herein, we report a case of a 58-year-old patient with a recent diagnosis of cutaneous melanoma who consulted for floaters and presented vitreous opacities in both eyes. A diagnostic vitrectomy of his left eye was performed and pathologic analysis disclosed infiltrating melanoma cells in the vitreous. Treatment with dabrafenib (a type of BRAF inhibitor) achieved the regression of the intraocular metastasis in the right eye. Moreover, the patient presented a severe anterior uveitis due to dabrafenib, a well-known secondary effect of this drug
Prediction Error Stabilization and Long-Term Standard Results with a Monofocal Intraocular Lens
The aim of this study was to assess the stability and differences between objective (O-Rx) and subjective (S-Rx) refraction for the assessment of the prediction error (PE). A secondary aim was to report the results of a monofocal intraocular lens (IOL). 100 subjects were included for whom S-Rx and O-Rx were obtained for all visits, and for visual performance, posterior capsular opacification incidence and Nd:YAG rates at 12 months. Either S-Rx and O-Rx showed a hyperopic shift from 1 to 6 months (p < 0.05) and stabilization after 6 months. S-Rx was related with the axial length (rho = −0.29, p = 0.007), obtaining a major tendency towards hyperopia in short eyes implanted with high-power IOLs. O-Rx showed a myopic shift in comparison to S-Rx (p < 0.05). This resulted in a decrease of the number of eyes in ±0.50 D and ±1.00 D from 79 to 67% and from 94 to 90%, respectively. The median (interquartile range) uncorrected and corrected visual acuities were 0.1 (0.29) and 0 (0.12) logMAR, respectively, and seven eyes required Nd:YAG capsulotomy at 12 months. Some caution should be taken in PE studies in which O-Rx is used or S-Rx is measured in a 1-month follow-up. Constant optimization should be conducted for this IOL after S-Rx stabilization.This work has received financial support from the Medtech Initiative, promoted by the Department of Health and Lehendakaritza through the Basque Government’s Innovation Fund
Creation of a neovascular age-related macular degeneration national database using a web-based platform: Fight Retinal Blindness Spain. Report 1: Visual outcomes
Background: To study the visual outcomes of neovascular AMD (nAMD) treated with anti-vascular endothelial growth factor (VEGF) drugs at national level. Methods: Multicenter national database of nAMD eyes treated with anti-VEGF intravitreal injections (ranibizumab, aflibercept, bevacizumab) in fixed bimonthly (FB) or treat-and-extend (TAE) regimens. Demographics, visual acuity (VA) in logarithm of the minimum angle of resolution (logMAR) ETDRS letters at baseline and subsequent visits, number of injections and visits data were collected using a validated web-based tool (Fight Retinal Blindness!). Results: 1273 eyes (1014 patients) were included, 971 treatment naïve (TN) and 302 previously treated (PT). Baseline VA (mean ± SD) was 57.5 (±19.5) and 62.2 (±17) (p > 0.001), and 24 months final VA was 60.4 (±21.2) and 58.8 (±21.1) (p = 0.326), respectively. Mean VA change at 12/24 months was +4.2/+2.9 letters in TN eyes and +0.1/-3.4 letters in PT eyes (p < 0.001/p < 0.001). The percentage of ≥15 letters gainers/losers at 24 months was 24.8%/14.5% in TN, and 10.3%/15.7% in PT eyes. The median number of injections/visits at 12 months was 7/9 in TN and 6/8 in PT (p = 0.002/p < 0.001) and at 24 months was 11/16 in TN and 11/14 in PT (p = 0.329/p < 0.001). Study drugs included ranibizumab (39.5%), aflibercept (41.2%) and bevacizumab (19.3%). Conclusion: Independent, large-scale national audits are feasible if committed health care professionals are provided with efficient information technology systems to do them. The results described here represent an adequate measurement of the quality of care delivered nationwide and benchmark the clinical management of nAMD at a country level compared to other real-world international cohorts.

Three-Year Outcomes of Neovascular Age-Related Macular Degeneration in Eyes That Do Not Develop Macular Atrophy or Subretinal Fibrosis
Purpose: To report the 36-month treatment outcomes of eyes with neovascular age-related macular degeneration (nAMD) receiving vascular endothelial growth factor (VEGF) inhibitors in daily practice who did not develop either subretinal fibrosis (SRFi) or macular atrophy (MA).
Methods: This is a retrospective analysis of data from the Fight Retinal Blindness registry. Treatment-naïve eyes starting intravitreal injection of VEGF inhibitors for nAMD from January 1, 2010, to September 1, 2017, and did not have SRFI and MA at baseline were tracked.
Results: We identified 2478 eligible eyes, of which 1712 eyes did not develop SRFi or MA, 291 developed extrafoveal SRFI or MA, and 475 developed subfoveal SRFi or MA over 36 months. The estimated visual acuity stabilized from 6 months to 36 months in eyes that did not develop SRFI or MA with a mean (95% confidence interval [CI]) change in VA of -1 (-2, 0) letters, whereas eyes that developed extrafoveal (-3 [-5, -2] letters) or subfoveal (-10 [-11, -8] letters) SRFi or MA declined in vision in the same period. Eyes with no or extrafoveal SRFi or MA over 36 months were more likely to maintain their visual improvement from six months to 36 months (odds ratio [OR; 95% CI] = 2.3 [1.5, 3.3] for absence vs. subfoveal SRFi or MA, P ≤ 0.01 and OR = 2.0 [1.2, 3.4] for extrafoveal vs. subfoveal MA or SRFi, P = 0.01).
Conclusions: Treatment-naïve nAMD eyes receiving VEGF inhibitors maintain their initial six-month visual improvement over three years if they do not develop SRFI or MA.
Translational relevance: The nAMD is still a major cause of blindness despite antiangiogenic treatments. We found that eyes that did not develop subretinal fibrosis or macular atrophy maintained their initial vision improvement for at least three years, suggesting that identifying treatments for these complications is the final barrier to achieving excellent outcomes in nAMD

Recommendations for ophthalmologic practice during the easing of COVID-19 control measures
In the context of the COVID-19 pandemic, this paper provides recommendations for medical eye care during the easing of control measures after lockdown. The guidelines presented are based on a literature review and consensus among all Spanish Ophthalmology Societies regarding protection measures recommended for the ophthalmologic care of patients with or without confirmed COVID-19 in outpatient, inpatient, emergency and surgery settings. We recommend that all measures be adapted to the circumstances and availability of personal protective equipment at each centre and also highlight the need to periodically update recommendations as we may need to readopt more restrictive measures depending on the local epidemiology of the virus. These guidelines are designed to avoid the transmission of SARS-CoV-2 among both patients and healthcare staff as we gradually return to normal medical practice, to prevent postoperative complications and try to reduce possible deficiencies in the diagnosis, treatment and follow-up of the ophthalmic diseases. With this update (5th) the Spanish Society of Ophthalmology is placed as one of the major ophthalmology societies providing periodic and systematized recommendations for ophthalmic care during the COVID-19 pandemic
