ABSTRACT
This retrospective study aimed to investigate the progression of central retinal vein occlusion (CVO) prior to treatment initiation and its impact on prognosis. Of the 54 studied eyes with acute CVO, the average logMAR visual acuity (VA) at the initial visit was 0.65 ± 0.49 with an average time to treatment of 14.9 ± 14.5 days. VA at the initial treatment was identified as a stronger predictor of VA at the final visit compared to VA at the first visit or other factors. Patients who received treatment more than 28 days after the initial visit experienced a significant decline in VA compared to those treated within 28 days (0.21 ± 0.35 vs. 0.04 ± 0.13, p = 0.006). Additionally, patients who were treated between 15 and 28 days showed a greater decrease in VA compared to those treated within 14 days (0.12 ± 0.46 vs. 0.018 ± 0.02, p = 0.026). These findings from the current retrospective analysis suggesting that there is a possibility of VA decline at the initial treatment associating with worse prognosis even when treatment is administered within a month should be further investigated in the prospective study. Also, it may be crucial to consider frequent monitoring of acute CVO patients for initiating treatment at the optimal timing.

OBJECTIVE: To investigate the association between serum soluble fms-like tyrosine kinase-1 (sFlt-1) and the choroidal structure during the pregnancy. METHODS AND ANALYSIS: This prospective study enrolled 24 eyes of 12 consecutive healthy pregnant women. Each participant was evaluated during the first, second and third trimester of pregnancy and the postpartum period. The central choroidal thickness (CCT) and Choroidal Vascular Index (CVI) were measured using enhanced depth-imaging optical coherence tomography. Moreover, serum sFlt-1 and vascular endothelial growth factor (VEGF) concentrations were measured manually using ELISA. The association between choroidal structural parameters and serum sFlt-1/VEGF was analysed using a linear mixed model. RESULTS: The CCT was significantly thicker in the second and third trimester than the postpartum period (p<0.05). In contrast, there was no significant difference in the CVI throughout pregnancy or the postpartum period. Serum sFlt-1 levels were significantly higher during pregnancy than the postpartum period (p<0.05), whereas the serum VEGF levels were significantly lower during pregnancy than the postpartum period (p<0.05). Furthermore, serum sFlt-1 levels were significantly associated with CCT throughout pregnancy (p=0.011, linear mixed model). On the contrary, sFlt-1 levels was not associated with the CVI during the pregnancy. CONCLUSION: Our results suggest that serum sFlt-1 might have an influence on the choroidal thickness during the pregnancy.
ABSTRACT
We report a case of bilateral iridoschisis with corneal oedema and a quantitative evaluation of the changes in iridotrabecular and iridocorneal contact before and after cataract surgery and after Descemet stripping automated endothelial keratoplasty (DSAEK). A 76-year-old woman with iridoschisis and cataracts, previously managed with laser iridotomy, experienced progressive vision loss. The preoperative iridotrabecular contact (ITC) index measured by anterior segment optical coherence tomography was 23.6% in the right eye and 24.4% in the left eye. Preoperative corneal oedema in the right eye was more severe than that in the left eye. Cataract surgery, followed by DSAEK, was performed in the right eye and subsequently in the left eye. Her visual acuity improved postoperatively, and the corneal oedema of both eyes was treated successfully. Moreover, the ITC index improved in both eyes, to 4.7 and 6.9% after cataract surgery and to 0 and 0% after DSAEK in the right and left eyes, respectively. Staged cataract surgery and DSAEK were effective for endothelial decompensation caused by iridoschisis. Additionally, we confirm that iridotrabecular and iridocorneal contacts improved after both surgical procedures not only after cataract surgery but also after DSAEK. This case report showed the clinical usefulness of the ITC index in the detection of changes after different surgical procedures.
ABSTRACT
We report a case of rapidly changing serous retinal detachment (SRD) during melanoma therapy with a combination of encorafenib, a serine/threonine-protein kinase B-Raf (BRAF) inhibitor, and binimetinib, a mitogen-activated protein kinase (MEK) inhibitor. A 50-year-old woman with metastatic melanoma presented with a sudden visual blur. She had been treated with encorafenib (450 mg every morning) and binimetinib (45 mg every 12 hours) after surgery for four months. Ophthalmological examination revealed bilateral SRD, but it was completely resolved after two hours. Visual acuity was normal in each eye. Encorafenib and binimetinib were continued. Shallow SRD appeared again five months later, but it resolved in two months. MEKAR typically occurs shortly after the start of an administration, and its development after several months was very little known. Continued examination for ophthalmic events should be considered.
