Aim To explore associations between artificial intelligence (AI)-based fluid compartment quantifications and 12 months visual outcomes in OCT images from a real-world, multicentre, national cohort of naïve neovascular age-related macular degeneration (nAMD) treated eyes. Methods Demographics, visual acuity (VA), drug and number of injections data were collected using a validated web-based tool. Fluid compartment quantifications including intraretinal fluid (IRF), subretinal fluid (SRF) and pigment epithelial detachment (PED) in the fovea (1 mm), parafovea (3 mm) and perifovea (6 mm) were measured in nanoliters (nL) using a validated AI-tool. Results 452 naïve nAMD eyes presented a mean VA gain of +5.5 letters with a median of 7 injections over 12 months. Baseline foveal IRF associated poorer baseline (44.7 vs 63.4 letters) and final VA (52.1 vs 69.1), SRF better final VA (67.1 vs 59.0) and greater VA gains (+7.1 vs +1.9), and PED poorer baseline (48.8 vs 57.3) and final VA (55.1 vs 64.1). Predicted VA gains were greater for foveal SRF (+6.2 vs +0.6), parafoveal SRF (+6.9 vs +1.3), perifoveal SRF (+6.2 vs −0.1) and parafoveal IRF (+7.4 vs +3.6, all p<0.05). Fluid dynamics analysis revealed the greatest relative volume reduction for foveal SRF (−16.4 nL, −86.8%), followed by IRF (−17.2 nL, −84.7%) and PED (−19.1 nL, −28.6%). Subgroup analysis showed greater reductions in eyes with higher number of injections. Conclusion This real-world study describes an AI-based analysis of fluid dynamics and defines baseline OCT-based patient profiles that associate 12-month visual outcomes in a large cohort of treated naïve nAMD eyes nationwide.

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.

To estimate the economic impact for the society, generated as a consequence of the onset of loss of vision and irreversible legal blindness, for the main ophthalmologic diseases in Spain: glaucoma, diabetic retinopathy (DR), diabetic macular edema (DME), age-related macular degeneration (AMD) and high myopia (HM). A cost analysis model was developed to estimate the economic burden of glaucoma, DR, DME, AMD and HM over a 10-year time horizon (2021-2030), from a societal perspective in Spain. The epidemiological and economic parameters used in the model were obtained through a literature review. Prevalence, incidence, and progression stages were used to establish the epidemiological flows. Annual costs per patient from publications were included and classified into direct healthcare, direct non-healthcare and indirect costs. Costs from other countries were converted based on purchasing-power-parity (€EUR, PPP). Epidemiological parameters about population and cost results were validated by a panel of experts. All costs were adjusted to euros, 2021 (€, 2021), and using the Consumer Price Index (CPI) of the last 10 years, extrapolated to 2030 euros (€, 2030). It was estimated that the total population of patients with the main diseases pathologies (glaucoma, DR, DME, AMD and HM) will increase to 7.99 million patients by 2030, representing an increase of 103%. The total cost by 2030 of all pathologies would amount to 99.8 billion euros. Direct non-healthcare costs account for the largest item (44%), followed by loss of productivity costs (38%), and direct healthcare costs (18%). The pathologies with the highest cumulative costs will be glaucoma (€33.6 billion) and DME (€19.8 billion).The greatest increment costs compared to 2021 will likely be generated by pathologies related to diabetes mellitus, such as DR (703%) and DME (317%). Knowing the costs associated with the pathologies that generate loss of vision and irreversible legal blindness is essential to understand the socioeconomic impact associated with these pathologies. Furthermore, the high cost of treating these diseases makes necessary to coordinate efforts between administrations, together with the support of patient associations, to meet their needs.

Purpose: To evaluate the long-term effects of intravitreal dexamethasone implants (IDIs) in eyes with macular edema (ME) due to retinal vein occlusion (RVO). Methods: We reviewed the records of 10 patients followed for 5 years after they received their first IDI. The main outcome measures included changes in best corrected visual acuity (BCVA), central macular thickness (CMT), and central macular volume (CMV), and the incidence of side effects. Results: Ten patients were included in the study with a mean follow-up of 65.51 months. Forty IDI injections were performed. An improvement in BCVA was observed after 92.5% of the IDI injections (P < 0.05), while the CMT and the CMV decreased significantly (P < 0.05) after 97.5% of the injections. After 27.5% of the injections, the intraocular pressure rose more than 10 mmHg and 3 of the 7 phakic patients required phacoemulsification surgery. Conclusion: IDI is an effective therapy for the treatment of ME secondary to RVO with a favorable long-term safety profile.

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.

Aim To evaluate the impact of fluid volume fluctuations quantified with artificial intelligence in optical coherence tomography scans during the maintenance phase and visual outcomes at 12 and 24 months in a real-world, multicentre, national cohort of treatment-naïve neovascular age-related macular degeneration (nAMD) eyes. Methods Demographics, visual acuity (VA) and number of injections were collected using the Fight Retinal Blindness tool. Intraretinal fluid (IRF), subretinal fluid (SRF), pigment epithelial detachment (PED), total fluid (TF) and central subfield thickness (CST) were quantified using the RetinAI Discovery tool. Fluctuations were defined as the SD of within-eye quantified values, and eyes were distributed according to SD quartiles for each biomarker. Results A total of 452 naïve nAMD eyes were included. Eyes with highest (Q4) versus lowest (Q1) fluid fluctuations showed significantly worse VA change (months 3–12) in IRF −3.91 versus 3.50 letters, PED −4.66 versus 3.29, TF −2.07 versus 2.97 and CST −1.85 versus 2.96 (all p<0.05), but not for SRF 0.66 versus 0.93 (p=0.91). Similar VA outcomes were observed at month 24 for PED −8.41 versus 4.98 (p<0.05), TF −7.38 versus 1.89 (p=0.07) and CST −10.58 versus 3.60 (p<0.05). The median number of injections (months 3–24) was significantly higher in Q4 versus Q1 eyes in IRF 9 versus 8, SRF 10 versus 8 and TF 10 versus 8 (all p<0.05). Conclusion This multicentre study reports a negative effect in VA outcomes of fluid volume fluctuations during the maintenance phase in specific fluid compartments, suggesting that anatomical and functional treatment response patterns may be fluid-specific.
