The longer eye axis is caused by strike of high energy photon. Blue light and X-ray from screen are two kinds of high-frequency electromagnetic radiation which can shot hole in eye and cause myopia. Healing the shot hole can cure myopia.","PeriodicalId":91939,"journal":{"name":"Open access journal of ophthalmology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84095353","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}

Methods: A double blind randomized controlled trial was conducted on 50 subjects (75 eyes). The randomization divided the subjects into two groups, the 1000 mg group and the 500 mg group. The evaluations were performed after 30 days and 60 days intervention by assessing Mean Deviation (MD) and Pattern Standard Deviation (PSD) of Humphrey Visual field as well as retinal nerve fiber layer (RNFL) and Ganglion Cell-Inner Plexiform Layer (GCIPL) on ocular imaging. Results: After 60 days, there was no significant difference between both groups in the MD, PSD, RNFL, and GCIPL values. The median MD increased in the 1000 mg group from -9.96 dB at baseline to -5.0 dB after 60 days and from the intragroup analysis, there was a significant difference (p=0.008). Based on subgroup analysis, there was also significant difference before and after the intervention in the mild glaucoma receiving 500 mg citicoline and in moderate-severe glaucoma receiving 1000 mg citicoline. RNFL and GCIPL thickness in both groups were tended to be stable. A side effect of nausea was found in two subjects who each received a dose of 500 mg and 1000 mg citicoline. Conclusion: There was an improvement in the MD and PSD values in both groups after 60 days of oral citicoline administration, but a significant difference was found in mild glaucoma group receiving 500 mg citicoline and in moderate-severe glaucoma receiving 1000 mg citicoline. The thickness of RNFL and GCIPL in both groups did not decrease after 60 days of citicoline administration.","PeriodicalId":91939,"journal":{"name":"Open access journal of ophthalmology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83809961","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}

A placoid-like presentation of this condition is unusual and it can mimic other causes, such as syphilis. Complete evaluation and early treatment might improve visual outcome and decrease number of recurrent episodes. Case Presentation: We report a case of a 21 year-old female patient with progressive low visual acuity in both eyes and a placoid-like lesion associated with serous retinal detachment in the fundus exam. Optical coherence tomography showed a highly reflective subretinal membranous structure and subretinal fluid. Fluorescein angiography showed multiple areas of pinpoint leakage and optic disk staining. Other ancillary exams, such as serology and head/orbit computerized tomography were all normal. Cerebrospinal fluid revealed pleocytosis. The diagnosis of Vogt-Koyanagi-Harada was made and prompt treatment with high-dose systemic corticosteroid was started. The patient had a complete recovery of her visual acuity and has had no recurrence of inflammation so far. Conclusion: This article describes an unusual presentation of Vogt-Koyanagi-Harada disease evaluated with multimodal imaging and also highlights the benefits of the early diagnosis and prompt management.","PeriodicalId":91939,"journal":{"name":"Open access journal of ophthalmology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79440586","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}

This positioning was to answer the question whether the asymmetry of the lens structure in combination with the asymmetry of the position and the size of the pupil will have an impact on the obtained visual acuity to far and near distances. In the first variant, the part of the lens responsible for vision to far distances was more exposed in the pupil, while in the second - the part responsible for vision to near distances was positioned in this way. Taking into account the size of angle kappa, not exceeding the value of 0.640 mm, moderate, statistically significant correlations were found between the size of the pupil and the visual acuity to near distances in one position and to far distances in the other position.

On general examination, he was of normal built and height for his age. Upon ocular examination, his BCVA was 6/9 in both eyes. Slit-lamp microscopic examination showed clear cornea in both eyes. Pupils of both eyes were round, regular and reacting. Lens was clear in both eyes. Fundus examination revealed discrete yellow lesions at the fovea of both eyes. Optical coherence tomography scanning showed corresponding retinal pigment epithelial defects in both eyes.

Methods: A cross sectional study was done of all patients with PCR from June to November 2021 in a Tertiary eye care Hospital. In this study, distribution of the respondents by age, the morphology of cataract, risk factors for PCR, Surgeon’s experience, percentage of Phaco and SICS, in which steps of surgery PCR occurred, implantation of IOL following PCR were analyzed. The final visual outcome of cases with PCR was measured. Results: Among 7650 patients, who underwent cataract surgery during the study period, 142 had eventful cataract surgery with various per operative complications, and PCR was the most common (n = 94). Most of the study population was in the age group 61-70 years (37.2%). About 45% were male, and 55% were female. Among 94 cases, PCR occurred in 65 patients (69.1%) during Phaco and 29 (30.8%) cases during SICS. There was no statistically significant difference between Phaco and SICS for PCR (> 0.05). In most patients (26.1%), PCR occurred during cataract surgeries irrigation and aspiration step. The most common risk factors for developing PCR were small pupil (10.6%) and corneal opacity (9.5%). PCR was higher by trainee surgeons rather than by senior surgeons. There was a statistically significant improvement in postoperative visual acuity even when PCR occurred during surgery (P< 0.001). Conclusions: PCR occurs in all cataract surgeries and is the main intraoperative complication. This study identified the incidence rate and risk factors of occurring PCR during cataract surgery in a tertiary eye hospital of Bangladesh, which may assist in the application of preventive measures to decrease rates of PCR. Eyes having posterior capsule rupture at the time of cataract surgery have a significant risk of reduced visual acuity.","PeriodicalId":91939,"journal":{"name":"Open access journal of ophthalmology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83126138","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}

In the eye, ROCKs are involved in the development of glaucoma, Fuchs corneal dystrophy, diabetic retinopathy and age-related macular degeneration.
