The ab externo method utilized conventional sutured techniques, while the trocar-cannula-based sutureless method was adapted from the \"Yamane\" technique, employing a wide-angle fundus lens to facilitate IOL manipulation in the vitreous cavity. The four-point fixation method involved a double-armed polypropylene suture and two 26-gauge needles to secure the four IOL haptics at four distinct sites. One-way analysis of variance (ANOVA) was used for statistical comparison between the groups.Results: The four-point fixation group exhibited superior best-corrected visual acuity compared to the sutureless and ab externo groups at 1 and 3 months postoperatively (P = 0.004 and P = 0.002, respectively), along with significantly less surgically induced astigmatism (P < 0.001). The sutureless group had the shortest operative time, while the ab externo group had the longest (P < 0.001). No instances of IOL iris capture occurred in the four-point group, while three cases (10.0%) were noted in the sutureless group.Conclusion: The four-point fixation technique provides significant benefits, including faster visual recovery, enhanced IOL stability, and lower surgically induced astigmatism (SIA) values. The sutureless technique provides the benefit of shorter operative times but does pose a risk of IOL capture in a limited number of cases.","PeriodicalId":13329,"journal":{"name":"Indian Journal of Ophthalmology","volume":"73 3","pages":"422-428"},"PeriodicalIF":2.1,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143500678","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Rescan 700 SD-OCT system was used for intraoperative imaging. These patients were imaged using intraoperative SD-OCT after implantation of the IOL and before and after implantation of appropriate size of CTR. The vertical height between posterior surface of the lens capsule and the posterior surface of the IOL was measured and compared across 3 CTR sizes.Results: The vertical height between the posterior surface of the lens capsule and the posterior surface of the IOL reduced significantly post CTR implantation (P value < 0.001) in all three groups. The change in height after CTR implantation was seen highest with the CTR size 13 mm and lowest with CTR size 11 mm.Conclusion: Significant improvement of contact between the IOL and the posterior capsule was shown after implantation of the CTR. Larger the size CTR, more the contact of the IOL with the bag was shown.","PeriodicalId":13329,"journal":{"name":"Indian Journal of Ophthalmology","volume":"73 3","pages":"341-345"},"PeriodicalIF":2.1,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143500686","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

All patients underwent both systemic and ocular assessments, regardless of their presenting symptoms. Ocular complications, particularly ACG, were managed with topical and systemic treatments. Data collected included demographic information, type of snakebite, systemic symptoms, treatment outcomes, and ocular findings.Results: Of the 126 patients admitted with venomous snakebites, 84 presented with neurotoxic bites and 42 with hematotoxic bites. Nine patients developed bilateral ACG, all of whom had sustained hematotoxic bites. Visual acuity (VA) ranged from hand motion to 6/9, with elevated intraocular pressure (IOP) ranging between 12 and 54 mm of Hg. Systemic complications included acute renal failure in 16 hematotoxic cases, with four patients requiring hemodialysis and subsequently succumbing to renal failure and multiorgan dysfunction. After treatment with antisnake venom, topical IOP-lowering agents, corticosteroids, and systemic therapies, five patients demonstrated full recovery, with normalized IOP and improved VA.Conclusion: ACG is a significant but underreported complication of hematotoxic snakebites. Early detection and intervention, including routine ocular screening, are crucial to prevent visual impairment. Ocular involvement may also serve as a prognostic indicator of severe systemic envenomation.","PeriodicalId":13329,"journal":{"name":"Indian Journal of Ophthalmology","volume":"73 Suppl 2","pages":"S298-S302"},"PeriodicalIF":2.1,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143467913","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The average thickness of mGCIPL and pRNFL on spectral domain-OCT and macular vessel density (VD), optic nerve head (ONH) perfusion, and ONH flux index (FI) on OCTA were evaluated for early diagnosis of glaucoma.Results: Macular VD, ONH perfusion, and ONH FI were significantly reduced in early POAG eyes compared to normal. The best correlation was observed between ONH FI and the average RNFL in both glaucoma suspects ( r = 0.47, P < 0.01) and early POAG patients ( r = 0.53, P < 0.01). Out of all the measured OCTA parameters, only ONH perfusion was significantly lower in glaucomatous eyes compared to glaucoma suspects ( P < 0.001). Average GCIPL (0.82) and macular VD (0.76) had the highest area under the receiver operating characteristic (AUROC) curve value among all the OCT and OCTA parameters, respectively, for differentiating glaucoma suspects from controls. Rim area (0.92) and ONH FI (0.81) had the highest AUROC value among all the OCT and OCTA parameters for differentiating early POAG patients from controls.Conclusion: OCTA vascular parameters had a good correlation with structural damage both at the disc and the macula. OCT parameters were superior to OCTA parameters for diagnosis of glaucoma, although OCTA parameters are deranged very early in the disease.","PeriodicalId":13329,"journal":{"name":"Indian Journal of Ophthalmology","volume":" ","pages":"S260-S266"},"PeriodicalIF":2.1,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142499470","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
