For the left eye, the diagnosis was made: Irregular post-keratoplastic astigmatism of a high degree, condition after penetrating keratoplasty, posterior capsular cataract. To correct the irregular post-keratoplastic astigmatism, the patient underwent the MyoRing implantation into the corneal graft. Then, 1 year later, the patient underwent cataract phacoemulsification with a toric intraocular lens implantation for the simultaneous correction of residual corneal astigmatism. The follow-up period after phacoemulsification was 1 year. One year after the MyoRing implantation into the corneal graft, uncorrected visual acuity and corrected visual acuity increased from 0.02 to 0.05, corneal astigmatism decreased by 4.46 D and became significantly more regular. 1 month after phacoemulsification with toric intraocular lens implantation, uncorrected visual acuity increased from 0.05 to 0.8, corrected visual acuity from 0.05 to 1.0; spherical and cylindrical components of refraction amounted to 0.5 D each and did not change anymore. \u0000The combined method of irregular post-keratoplastic astigmatism correction in a patient with cataract showed a high refractive result, stability and safety in the late postoperative period.","PeriodicalId":10836,"journal":{"name":"Current Ophthalmology Reports","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2023-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84561733","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}

All subjects underwent Maklakov applanation tonometry (10 g) and pachymetry (Topcon SP-3000P). In 48 patients (94 eyes) of the 1st group, pneumotonometry (TONOREF II Nidek) was performed, and 27 patients of the 2nd group (52 eyes) underwent rebound tonometry (iCare IC-100). \u0000RESULTS: The mean difference in intraocular pressure level in the 1st group was 4.81 (p 0.001), and in the 2nd 0.98 mmHg (p = 0.399). Both methods pneumo- and rebound tonometry showed underestimated results with intraocular pressure less than 23.0 and 22.5 mmHg (respectively) relative to applanation tonometry and, conversely, overestimated intraocular pressure when these values were exceeded. A significant (p 0.001) strong (R2 = 0.86) relationship between applanation and rebound tonometry was obtained, which made it possible, using regression analysis, to develop a formula for recalculating results of iCare tonometry into those of Maklakov tonometry: PMaklakov = 0.40 PiCare + 13.44. \u0000CONCLUSIONS: Both pneumo- and rebound tonometry demonstrate adequate results of P0 with intraocular pressure below 23.0 and 22.5 mmHg (respectively) and overestimate the results when these values are exceeded. The developed formula allows converting the results of iCare tonometry into the values of the Maklakovs tonometry.","PeriodicalId":10836,"journal":{"name":"Current Ophthalmology Reports","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2023-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79417706","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}

Zharov","doi":"10.17816/ov173174","DOIUrl":"https://doi.org/10.17816/ov173174","url":null,"abstract":"BACKGROUND: Optical coherence tomography angiography (OCTA) is a noninvasive method of eye microcirculation evaluation. Few reports are published on the use of OCTA for anterior segment (AS) vessels analysis in healthy eyes and in conjunctival tumors, and their vascular characteristics are still not thoroughly investigated. These questions are of importance, as it is known that tumors vasculature is indicative of the patients vital prognosis. \u0000AIM: The aim of our study was to investigate the potential of AS-OCTA in evaluation of normal conjunctival vessels architecture as well as that in melanocytic neoplasms. \u0000MATERIALS AND METHODS: 20 healthy volunteers (20 eyes) and 20 patients (20 eyes) with conjunctival nevi and melanomas were examined. AS optical coherence tomography (OCT) and AS-OCTA were performed. Scan analysis included qualitative assessment (vessels pattern, lumen, tortuosity) and quantitative assessment [perfusion density (PD, %) index]. Mean (MPD), maximum (MaxPD) and perifocal PD (PPD) were determined. \u0000RESULTS: In normal group, predominantly radial pattern of the vessels was revealed, their caliber remaining the same along their entire length; larger vessels were more often discovered in deep conjunctival layers. The lowest PD value (29.9%) was registered in the inferior conjunctival segment, and the highest (36.7%) in the nasal one. In the conjunctival tumors area tortuosity of the vessels, uneven vessels caliber along their length, and increase in the PD value were observed. Melanomas were characterized by an increase in the lace-like pattern and by presence of confluent pattern zones; MaxPD value was more than 50%. Significant difference was found between MPD values of normal conjunctiva and MPD values in conjunctival melanoma. \u0000CONCLUSIONS: AS-OCTA is an informative method for the visualization of vessels in normal conjunctiva and in conjunctival tumors. If the tumors vessels are unevenly distributed, MaxPD should be measured.","PeriodicalId":10836,"journal":{"name":"Current Ophthalmology Reports","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2023-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73846899","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}
