Methods Prospective, interventional case series of eyes that were diagnosed with active neovascular AMD. Spectral-domain optical coherence tomography (SD-OCT) and OCTA were done at baseline after intravitreal antivascular endothelial growth factor (anti-VEGF) treatment to determine OCTA sensitivity in the detection of activity in relation to SD-OCT findings and its specificity following intervention. Results Twenty-five eyes were included, of which 20 eyes were imaged successfully by OCTA. The diagnostic sensitivity of OCTA in those eyes was found to be 75%, and its sensitivity in the assessment of neovascular activity was 80 and 60%, before and after anti-VEGF therapy, respectively, whereas its specificity after anti-VEGFs therapy was 100%. Conclusion Although SD-OCT continues to be the gold-standard for noninvasively diagnosing and tracking neovascular AMD treatment response, OCTA may offer a noninvasive option that can support treatment selection throughout follow-up and guide efficient therapeutic approaches.

Patients and methods This single-center prospective randomized study included patients who were planned to receive an IVI of anti-vascular endothelial growth factor ranibizumab 0.05 ml for macular edema for diabetic macular edema, branch retinal vein occlusion, or choroidal neovascular membrane. Patients were randomized into five groups: no intervention (group 1), pre-injection topical brimonidine (group 2), pre-injection oral acetazolamide (Diamox) (group 3), pre-injection topical brimonidine and oral Diamox (group 4), and pre-injection paracentesis (group 5). The primary outcomes were the occurrence and degree of reflux following IVI. In addition, the evaluation of conjunctival bleb estimated the degree of reflux. Patient self-rated pain and early complications were secondary outcome measures. Results A total of 150 eyes of 150 patients were included. Vitreous reflux occurred in 13 (43%), 14 (46.7%), 19 (63.3%), six (20.0%), and four (13.3%) eyes in groups 1–5, respectively (P<0.001). Additionally, higher degrees of reflux were observed in group 1 compared with other groups. Discussion In our study, we raised the question of whether the intraocular pressure (IOP) before injection affects vitreous reflux. Therefore, we compared the effect of different antiglaucomatous medications on lowering the pre-injection IOP, and so decrease the vitreous reflux. We found that in both the paracentesis group and group of combined topical brimonidine and oral Diamox group, vitreous reflux rate is reduced significantly (P<0.001) because in these two groups, the IOP just before the injection was the lowest. Unfortunately, we could not measure the IOP after paracentesis and before the injection to avoid any risk of endophthalmitis, but we consider the paracentesis as a gold standard group for lowering IOP, although it is an invasive procedure. Interestingly, the self-rated pain rate was the same in all groups. Conclusion Pre-injection topical brimonidine combined with oral Diamox may be an effective and noninvasive method to prevent/reduce vitreous reflux following IVI.","PeriodicalId":31572,"journal":{"name":"Journal of the Egyptian Ophthalmological Society","volume":"116 1","pages":"24 - 27"},"PeriodicalIF":0.2,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42591194","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Human leukocyte antigen (HLA) typing helps in understanding the pathogenesis of several diseases. Limited knowledge is known regarding the association of HLA with idiopathic uveitis. Aim This was a cross-sectional observational case–control study evaluating HLA-A and HLA-B allelic and phenotypic frequencies in patients with idiopathic uveitis. Patients and methods HLA-A and HLA-B molecular typing by PCR-sequence-specific oligonucleotide probes and LIRAS interpretation software was performed for 60 patients with idiopathic uveitis and 60 controls recruited from Kasr Al-Ainy Hospitals, Cairo University. Results Anterior uveitis pattern was the most common (55%), followed by pan-uveitis (35%) and posterior uveitis (10%). Overall, 40% of patients had bilateral uveitis, whereas 60% had unilateral uveitis. A total of 23 HLA-A and 43 HLA-B variant alleles were detected. HLA-AFNx0109 and HLA-AFNx0110 allele and phenotype frequencies were significantly higher in the patient group (P=0.023 and 0.034, and P=0.013 and 0.029, respectively). HLA-BFNx0107 allele and phenotype frequencies were significantly higher in the control group (P=0.007 and 0.006, respectively). HLA-BFNx0127 and HLA-BFNx0105 were detected in 8.3 and 26.7%, respectively, with no significant difference. Conclusion HLA-AFNx0109 and HLA-AFNx0110 alleles were statistically significantly higher in patients with idiopathic uveitis. HLA-BFNx0107 might be a protective allele against disease development. Larger cohort needs to be tested to validate these findings. Routine HLA typing and proper follow-up for primarily diagnosed idiopathic uveitis is recommended as it might reveal secondary causes for uveitis, especially in patients with positive HLA-BFNx0127 and HLA-BFNx0105.","PeriodicalId":31572,"journal":{"name":"Journal of the Egyptian Ophthalmological Society","volume":"116 1","pages":"42 - 49"},"PeriodicalIF":0.2,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41431702","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Patients and methods The study was conducted on 100 eyes of 50 (37 females) patients seeking refractive surgery at a private eye center in Alexandria, Egypt. Following detailed history taking, all study participants were subjected to a thorough ophthalmic examination including assessment of uncorrected and best-corrected visual acuity, manifest and cycloplegic refraction, slit-lamp examination, measurement of intraocular pressure (IOP) using Goldmann applanation tonometry, and fundus examination using a high plus auxiliary lens. Optical coherence tomography and corneal biomechanical properties were then studied using the Reichert ocular response analyzer. Results The mean±SD age of the study patients was 25.27±4.9 years and of contact lens wear (24% of study patients) was 2.5±0.9 years. The mean±SD of the manifest refractive error was −5.6±5.2 D sphere and −1.6±1.2 D cylinder and of the best-corrected visual acuity was 0.9±0.2.
