Methods: A case series review was done among the patients who visited Chittagong Eye Infirmary and Training Complex from January 2015 to December 2018. Demographic data, clinical presentations, management and outcome were recorded and analysed. Results: 30 phacomorphic cases and 20 phacolytic glaucoma patients were included in our study. The mean age at presentation was 60 years. Female to male ratio was 2:1. The reason for late presentation was distance which was 60% in phacomorphic glaucoma and 50% in phacolytic glaucoma. The main symptoms were reduced vision followed by ocular pain and redness of eye. Visual acuity was either HM or just PL in all eyes before surgery. All patients underwent SICS with posterior chamber lens implantation. IOP reduced tremendously upon discharge and vision kept improving up to a month after surgery. Conclusion: Reduced vision, ocular pain and redness are the main clinical presentations of lens induced glaucoma. Cataract surgery proves to be effective in lowering IOP and visual recovery in patients with lens induced glaucoma.","PeriodicalId":91939,"journal":{"name":"Open access journal of ophthalmology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-01-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90528168","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}

C","doi":"10.23880/oajo-16000228","DOIUrl":"https://doi.org/10.23880/oajo-16000228","url":null,"abstract":"Clinical Relevance: Optometrists often are the first to examine previously underdiagnosed diabetic patients because of its ocular manifestations such as a change in refractive status. This study is relevant to help optometrists identify patients with diabetes using changes in pupil mydriasis as a marker. Background: This study compared the pupillary dilatation in subjects with diabetes mellitus and those without diabetes mellitus. The purpose of the study was to use this difference as a diagnostic marker for identification of diabetes in previously undiagnosed subjects who present for eye examination. Methods: An experimental study was conducted involving 40 non-diabetic and 80 diabetic subjects with or without diabetic retinopathy. Baseline pupil diameter was measured using Orbscan and Aberrometer. Mydriasis was elicited using a combination eye drop (0.8% Tropicamide and 5% Phenylephrine). Pupil diameter was measured at 15, 30, 45 and 60 minutes after the instillation of the eye drops. The difference in pupil diameter amongst the three groups was determined using factorial ANOVA to account for the effect of age. Results: There was no significant difference between the mean pupil diameter among the three groups at baseline when measured with Orbscan (p=0.187) and Aberrometer (p=0.146). There was a significant difference in the mean and mean change in pupil diameter among the three groups with either Orbscan or Aberrometer at 30, 45 and 60 minutes after the instillation of mydriatic drops. The non-diabetics have larger pupil diameter while the diabetics with retinopathy have the least pupil diameter. Conclusion: The study showed that there was a significant difference in pupil diameter between non-diabetics, diabetics without retinopathy and diabetics with retinopathy during mydriasis. Alongside a history of symptoms of diabetes, this difference could be explored as an ocular biomarker to identify previously undiagnosed diabetes in individuals who present for routine eye examination.","PeriodicalId":91939,"journal":{"name":"Open access journal of ophthalmology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72975898","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}

Some reports of ocular infections along with respiratory infection in the patients of COVID-19 were also reported during this pandemic. The ocular manifestation of this virus has not completely been established yet; hence more research is needed to confirm the association of SARS-CoV-2 with ocular infections. However few reports have already been published about the association of corona virus infections in various animals. Clinical symptoms such as conjunctivitis, retinitis, and anterior uveitis are documented in feline and murine models, which on diagnosis were proved due to the corona virus infections. In this review article, some evidences of the association of SARS-CoV-2 with ophthalmic infections in the current pandemic and some published reports of corona virus infections in some animals has been briefly highlighted. Simultaneously we have tried to explain briefly about some research ideas that may establish the ocular association of this virus. We have also tried to suggest some new visitor’s policies in ophthalmic settings and some preventive measures those can be obeyed by an Ophthalmologist and other associated staffs during consultation to prevent themselves and to break spread of infections. We hope that, this article will inspire some researchers and Ophthalmologists to establish the exact pathophysiology behind the SARS-CoV-2 infections in ocular system.","PeriodicalId":91939,"journal":{"name":"Open access journal of ophthalmology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81041544","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}

Study of this issue by multifocal electroretinogram (mf-ERG) revealed significant improvement in macular function associated with decreased retinal thickness using optical coherence tomography (OCT) and improvement of best corrected visual acuity (BCVA). Purpose: To study the role of multifocal Electroretinogram in the follow up of diabetic macular edema after intravitreal injection Ranibizumab and study its correlation to visual acuity and optical coherence tomography changes. Methods: A non-randomized prospective study was carried out from February 2018 to August 2018 on 32 eyes of patients with diffuse or focal DME without macular ischemia. The patients were selected from the outpatient ophthalmology clinic of Al-Hussein University hospital. The patients were injected intravitreally by Ranibizumab 0.5mg/0.05mL at baseline, 1 and 3 months. In this study we assessed pre and post-injection BCVA, IOP measurement by applanation tonometer, OCT and multifocal ERG changes over 3 months. Results: log MAR BCVA improved from (0.88±0.12) preoperatively to (0.53±0.18) at the end of the 3rd month, with P-value <0.001. Central subfield thickness 1 mm improved from (408.73±79.40µm) preoperatively to (224.33±32.49µm) at the end of the 3rd month, while para and peri-foveal thickness improved from (402±46.52µm) preoperatively to (286.30±32.67µm) at the end of the 3rd month, with P-value <0.001. P1 amplitude in ring 1 using MF-ERG improved from (33.08±10.59 nv/deg2) preoperatively to (58.30±32.67 nv/deg2) at the end of the 3rd month, with P-value<0.001. P1 amplitude in ring 2 using MFERG improved from (18.82±5.01 nv/deg2) preoperatively to (26.36±3.006 nv/deg2) at the end of the 3rd month, with P-value in the 1st month <0.05, while in the 3rd month <0.001. P1 implicit time in ring 1 using MF-ERG improved from (78.65±12.37 ms) preoperatively to (63.78±15.73 ms) at the end of the 3rd month, with P-value in the 1st month <0.05, while in the 3rd month <0.001. P1 implicit time in ring 2 using MF-ERG improved from (48.81±6.44 ms) to (44.39±4.06 ms) at the end of the 3rd month, with P-value in the 1st and 3rd months <0.05. Complications during follow up of patients especially 1week after injection were relatively uncommon, including mild subconjunctival haemorrhage in 1 eye (3.3%) and transient increase of IOP in 4 eyes (13.33%). Conclusion: Intravitreal injection of Ranibizumab resulted in improvement of macular function in study patients with diabetic macular edema.

The analysis of the mental process of perception with the help of perceptual influences on an object of variable form is carried out. For the study, experimental equipment in the form of a tablet was developed and a special program was created to record hand movements when applying perceptual influences. The subjects were students in grades 1-4. The idea is substantiated that a person with the help of a tactile and visual analyzer is able to accurately reveal the properties of softness, elasticity, and viscosity of objects. It was revealed that vision is a necessary component in their study. Based on the study of the problem, it has been established that vision \"prompts\" the hand to the correct trajectory for applying perceptual influence on the studied soft object.

Respiratory droplets transmit the virus; various body fluids and secretions such as nasopharyngeal swabs, stool, digestive tract, urine, saliva; few anecdotal reports indicate that the virus may be present in ocular secretions and possibilities of transmission by the lacrimal-pump mechanism through tears, thus posing a transmission risk. An exposed ocular surface acts as a gateway for various respiratory viruses. Looking at the nasolacrimal system anatomical and physiological aspects, it bridges the eye and respiratory tissues. Moreover, it can also share some common viral binding receptors. The eye is less frequently involved in SARS-CoV, and conjunctivitis is the only reported complication so far. The positivity of CoV RNA in conjunctival swabs tested by RT-PCR assay in confirmed SARS-CoV patients is low. The ocular route of coronavirus transmission and its detection in the ocular secretions is still controversial. In this narrative analysis, we reviewed the latest literature and explored an in-depth understanding of the ocular consequences of coronaviruses recorded up to now. The search took place for the corresponding journal through the use of the PubMed, PubMed Central (PMC), Daily situations reports, IPC (Invention Prevention Control) guidelines, WHO (World health organization), and from other Internet Sources. To avoid community transmission risk, the general public must also take precautionary measures in relation to the pandemic COVID-19.","PeriodicalId":91939,"journal":{"name":"Open access journal of ophthalmology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78317435","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}
