They are widely used chemotherapeutic agents that have been shown to be effective for various types of solid malignancies. Docetaxel-related bilateral toxic cystoid macular edema (T-CME) has been reported as a rare and unusual adverse reaction. We report a case of 43-year women treated for breast cancer with docetaxel and developed T-CME. She was treated with two cycles of Docetaxel 150 mg, Pertuzumab 420 mg and Trastuzumab 360mg. Three days after 2nd cycle she complained of diminution of vision. Her both eye visual acuity was 20/200. Fundus examination showed macular edema which was confirmed with SD-OCT and fluorescein angiography. After fourth cycle Docetaxel was stopped by treating physician. CME was completely resolved by three months. Several studies suggest that a cumulative dose seems necessary for the onset of the toxic effect of this drug. To our knowledge, we report the first case of Docetaxel-induced T-CME occurring within less than 1 month, with a very low cumulative dose. This suggests that no cumulative dose is needed for macular edema to appear.","PeriodicalId":287685,"journal":{"name":"Ophthalmology Research: An International Journal","volume":"146 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139258537","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}

Its mechanism is probably immuno-allergic. Patients and Methods: We report the first three cases of nummular keratitis related to a post-streptococcal infectious disease and we describe its clinical and tomographic aspect. Results: This is a new clinical entity, characterized by multiple rounded, whitish lesions 0.5 to 3 mm in diameter, located in the stroma. These plaques are made of small infiltrates arranged radially giving a “spoke wheel” appearance. With time, these infiltrates having a greater tendency to confluence and the plaques take on a “currency” appearance resembling those described by “Demmer”. Corneal sensitivity is preserved. Corneal optical coherence tomography (OCT) shows hyper-reflective lesions occupying the entire thickness of the stroma, with a \"flying saucer\" appearance respecting the corneal epithelium and endothelium with a tendency to confluence, particularly in the anterior stroma. Discussion: This keratitis can be unilateral or bilateral and associated with an inflammatory syndrome, a high titer of ASLO, and a streptococcal infection. Conclusion: Ophthalmologists faced with idiopathic nummular keratitis should consider post-streptococcal syndrome as a possible cause. A search for an increasing titer of ASLO and streptococcal infectious evidence establishes this association.","PeriodicalId":287685,"journal":{"name":"Ophthalmology Research: An International Journal","volume":"16 1-2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139256938","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}

We fixated 4 of these eyelashes with classical immersion oil and covered them with a coverslip. We wetted 4 of them with Proparacaine Hydrochloride 5 mg (0.5%) and painted them with Na-fluorescein, and covered them with a coverslip. \u0000Results: When we examined the eyelashes that were wetted with Proparacaine Hydrochloride under the light microscope there was no difference in mobility in the Demodex of the eyelashes at first 15 minutes.

True mono-canalicular intubation, using a flexible mono-canalicular probe with self-stabilizing meatic fixation, has several advantages over other lacrimal intubation techniques. The placement of this probe is essential, to ensure the correct alignment of the anastomosis and the lacrimal lumen during the healing phase, to prevent fibrosis and stenosis after canalicular repair and thus to maintain permeability.","PeriodicalId":287685,"journal":{"name":"Ophthalmology Research: An International Journal","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117149032","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}

Achieving sustained intraocular pressure that will retard the progression of the disease is the principal objective of its management. Many a times, this requires a combination of antiglaucoma medications, Lasers and surgery. No doubt, medical therapy is usually the mainstay of glaucoma management but in some cases, it fails to adequately control the intraocular pressure. The very effective surgical interventions for glaucoma depend on the health of the conjunctiva to achieve their success. So, meticulous evaluation of the conjunctiva is one of the indispensable preoperative considerations before deciding on any conjunctiva-dependent surgery. In addition, in managing any patient with ocular problem who also has glaucoma, it is imperative that the possibility of future surgery involving the conjunctiva must be considered. Therefore, the conjunctiva of all glaucoma patients must be handled with care.","PeriodicalId":287685,"journal":{"name":"Ophthalmology Research: An International Journal","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131308417","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}

Socio-demographic data and surgical history were obtained from patients and their surgical records. The PVA and BCVA were assessed and categorized based on World Health Organization guidelines.  \u0000Results: A total of 87 patients were examined within the study period. Post-operative PVA was good (≥6/18) in 32 (36.8%), borderline (<6/18-6/60) in 41 (47.1%) and poor (<6/60) in 14 (16.1%) participants. After refraction, the proportion of good outcomes increased to 78.2% with only 8.1% of outcomes remaining poor. Biometry-calculated IOL power and available IOL power use did not significantly influence visual outcome (P=.645 and P=.146 for PVA and BCVA respectively). \u0000Conclusion: Majority of participants had post-operative PVA in the borderline category with residual uncorrected refractive error as the principal cause. Regardless of the IOL power implanted, surgery for age-related cataract enhanced patients’ vision. This study has shown that the presence of biometry is a guarantee of refractive success. Hence, refractive outcome audits are essential.","PeriodicalId":287685,"journal":{"name":"Ophthalmology Research: An International Journal","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121845977","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}
