Abstract
Introduction: Diabetic retinopathy is a leading cause of nontraumatic blindness. Preventive measures and early detection will reduce the impact.

Objective: To investigate the attitudes and practical knowledge diabetics on diabetic retinopathy in 03 hospitals in Parakou in 2019

Methods: The study was conducted in 03 hospitals the CHUD / BA, The HIA / Parakou, Benin Diabetes Center. It was a prospective cross-sectional study descriptive and analytical type which covered a period of 03 months from 15 May to 20 August 2019; from a non-probability sampling with exhaustive survey of diabetics who have agreed, aged at least 18 years, residing in Parakou and followed in one of the centers. It has identified 150 patients who were subjected to a questionnaire.

Results: 59.33% were male. The average age was 55.07 ± 11.62 years. Subjects were predominantly married (87.33%); 62% of patients were educated. 48% of patients said that diabetes mellitus has ocular complications. 52% and 12% respectively of patients reported that glycemic control and normalizing blood pressure are factors in prevention. 27.33% of patients reported the need for regular review of the fundus. 12.67% of patients regularly receive an annual fundus examination and 56.67% of patients had never benefited of it. The education and sex were associated with the level of knowledge; education and low income were associated with the level of practice.

Conclusion: The reduction of the impact of diabetic retinopathy goes through greater involvement of the diabetic patient to the ophthalmologist, endocrinologist and the ministry of health authorities.

Keywords: Knowledge, attitude, practice, diabetic retinopathy, Parakou.

Abstract

Visual Evoked Potential (VEP) measures the electrical activity in the entire vision system.  When light enters the eye it is converted to electrical energy at the retina and travels through the optic nerve to the visual cortex which processes vision.  The Diopsys VEP test measures the strength and speed of the retinal signal all the way to the visual cortex. VEP technology uniquely helps determine the communication between the eye and the brain.  Electroretinography (ERG) measures retinal function.  When light enters the eye it is converted into electrical energy by cones and rods, visual cells.  ERG tests record the activity of the visual cells and thereby reflecting cell health and integrity. These two modalities are useful in diagnosing  cellular pathology such as Age Related Maculopathy(AMD), glaucoma,Diabetic Macula Edema(DME) ,amblyopia,brain injury, stroke and other vision related issues.  VEP is especially useful in Enfant and Pediatric exams to diagnose pathology.

Maha M Alanazi has her bachelor degree in optometry Doctor and visual science in 2018 King Saud University, Riyadh SA. She has Certificate of thanks and appreciation to participate in the Research day of the Optometry Department in the Collage. She Participated in Saudi Ophthalmology symposium April, 2018 as speaker of research title Testing the Validity of the Arabic Version of the Impact Vision Impairment (IVI-C) Questionnaire on Saudi Children with visual impairment.

Abstract:

BACKGROUND:

 Vision Related Quality of Life (VRQoL) in visual impairment children was accessed in The IVI-C questionnaire was translated to many languages and validated in many countries such as China(1) , Germany(2) , India(3) and Australia(4) using different translation of the Impact Vision Impairment of Children (IVI_C) questionnaire. However, VRQoL in visual impairment children in Saudi Arabia (SA) was not accessed. This is because there is no Arabic valid tool in the literature that can be used to access VRQoL. Therefore, there is a need for Arabic valid and reliable instrument that can be used to assess VRQoL in children with visual impairment.

AIM: The aim of this study was to test the validity and reliability of the Arabic version of the 23-item of IVI_C questionnaire on school-aged children with visual impairment in SA.

METHODS: This is a cross sectional study conducted in many low vision clinics in Riyadh, SA. The questionnaire was administered face-to-face to seventy-seven children with visual impairment who aged was ranged between 8 to 18 years old. Visual examinations include distance and near visual acuity were measured for all the participants. Rasch analysis was used to test the reliability and validity of the translated questionnaire.

RESULTS: The 23-item IVI-C questionnaire fit the Rasch analysis(5), person separation was 2.21, person reliability was 0.83 and the Cronbach alpha was 0.87. However, misfitted items were present. After deleting the misfitted items, the 14-item questionnaire had good validity and reliability as demonstrated by person separation and reliability (2.43,

0.86 respectively). The Cronbach alpha was 0.88. Person-item map of the 14-item showed good matching between children’s abilities and item difficulties.

CONCLUSION: The 14-item of the Arabic version of IVI-C questionnaire is valid and reliable tool on school aged children with vision impairment in SA, which can be used to assess VRQOL in children with visual impairment in Arabian countries. These items include several VRQoL domains such as accessed school/specialist instruction, social interaction, family, community and vision impairment peer interaction.

Keywords: low vision, children, questionnaire, vision-related quality of life, Rasch analysis.

Paul H Hughes is a renowned refractive surgeon in Australia gaining his BSc and MBBS from the University of NSW in Sydney, Australia. He introduced the early refractive procedures into Australia and was one of the first ophthalmologists to have his own private refractive suites, an ophthalmic centre of excellence (Southline eye centre).

He has made the journey from Refractive Keratectomy (RK) through Automated Lamellar Keratoplasy (ALK) to Photorefractive Keratectomy (PRK) then to laser in situ keratomileusis (LASIK) with the excimer laser and is now using the femtosecond laser (Visumax) to perform 3rd generation refractive surgery Small incision lenticule extraction (SMILE). Hughes has published many peer reviewed papers and spoken regularly at international ophthalmic meetings over the years. As a refractive surgeon he is very aware of the importance of Ocular Surface Disease (OSD) and its effect on excellent surgical outcomes

Abstract:

Abstract

 

Ocular surface disease is a common and often chronic condition that can have a lasting negative effect on quality of life and visual outcomes. The condition is extremely prevalent and environmental and lifestyle factors are partially responsible.

It is grossly under diagnosed and is exacerbated by surgical procedures and it affects refractivediagnostic techniques with poor keratometry affecting IOL calculations.

The literature describes several definitions, classifications and treatment methods and will be discussed in the paper.

The cause, differential diagnosis, masquerade syndrome and the various approaches to take in the treatment of OSD will be highlighted.Classification of dry eye disease will be discussed in detail compared to normal tear film physiology. The role of Meibomian gland dysfunction in the disease will be discussed.

Ocular surface disease data from the ESCRS 2018 Clinical Trends Survey Results will be mentioned.

OSD is a complex disease where treatment is dependent on the cause. There is no quick fixand it is essential to work together with the patient in developing a treatment plan to optimize the ocular surface prior to surgical procedures especially refractive.

Abstract:

Although there is no mention of acute glaucoma on the list of side effects of citalopram in some patient information leaflets, here have been previous published case reports on association of citalopram and other ssr is (selective serotonin reuptake inhibitirs) with acute glaucoma. It is the most severe ssr is related ocular complication.

Risk factor: race-asianorigin, hyper metropia, family history, female gender, age and shallow anterior chamber. Mechanism of ssri induced acute glaucoma is not clear.

An elderly lady with no previous history of glaucoma presented with acute headaches, bilateral ocular pain, photophobia ,worsening vision and fixed dilated pupils. With bilateral raised intra ocular pressures she was initially treated with systemic acetazolamide, ocular hypotensives  then bilateral yag iridotomy. Subsequently  stopped acetazolamide and pilocarpine.she returned with worsening vision and significantly raised iops this time. Her ultrasound b-scans remained unremarkable (though sometimes they can show typical findings).she was discussed with glaucoma specialist (rs) who asked for a full drug history and who stopped the oral citalopram subsequently. Her IPOS normalized improving her symptoms and vision markedly .

This patient had been seen a few times earlier , however, a comprehensive drug history was not obtained earlier. A low threshold for drug induced causes of bilateral acute glaucoma, including this as side effect in pils (patient information leaflet) and detailed ophthalmic examination including gonios copy should be carried out even in the presence of patent iridotomies in high risk patients. Warning advice and counselling to the patients should be given.

Abstract:

Objective: To evaluate the effects of virtual reality (VR) trainingon visual function.

 

Methods: Individuals with healthy eyes admitted to the First Affiliated Hospital of Zhejiang University and Shulan Hospital from November 2018 to June 2019 were divided into the short-term group (n = 40) and the long-term group (n = 20). They were given specially designed VR training devices only oncefor 15 minutes or 3–4 times a day for 15 minutes each time for one month. The changes in visual acuity, diopter, accommodative range, accommodative facility, pupil size, and visual fatigue were assessed before and after the test.

 

Results: After the use of the VR device for 15 minutes, the distant vision improved by-0.09 (95% CI, -0.12–-0.06,P< 0.001), the corrected visual acuity improved by-0.04 (95% CI, -0.06–-0.02, P< 0.001), the accommodation range increased by 0.41 (95% CI, 0.11–0.71, P = 0.008), the accommodative facility increased by 1.29 (95% CI, 0.84–1.74, P< 0.001), and the pupil contracted by -0.34(95%CI, -0.46–-0.22, P< 0.001). No changes were observed in the spherical equivalent diopter and the visual fatigue scale between the groups. The changes in distant vision (r = 0.361, P< 0.01) and corrected visual acuity (r = 0.516, P< 0.01) were positively correlated with the changes in the pupil size, but not with the changes in the spherical equivalent diopter (P> 0.05).After the use of the VR device for one month, the accommodative range improvedby0.69 (95% CI, 0.26–1.11, P< 0.01) and the accommodative facility improvedby 0.90 (95% CI, 0.45–1.35, P< 0.01); both parameters were markedly improved compared with before use. There were no significant changes in the distant vision, corrected vision, spherical equivalent diopter, pupil size, and visual fatigue (P> 0.05).

 

Conclusion: VR training can improve the accommodative range and facility. Although short-term VR training can transiently improve vision, due to pupil contraction caused by light adaptation, there is no evidence that it can improve myopia.

Abstract:

Aim:  To describe a case report of a patient with tectonic corneal grafts in both eyes who was unable to achieve functional vision with spectacles or soft contact lenses. The patient was with fit with Atlantis scleral lens in the left eye, and was able to have comfort and reasonably good vision.

Case summary: A 67 years old male diabetic patient with keratoconus who underwent tectonic grafts in both eyes for bilateral spontaneous corneal perforations. He visited our cornea clinic complaining of extremely poor vision; he couldn’t drive and was unable to find his way independently.

Examination showed: vision in the right eye counting fingers at 3 meters and left eye vision was 0.1. Slit lamp examination showed bilateral patch grafts inferiorly that were bulging forward. He was pseudophakic in both eyes. Dilated fundus examination with high resolution-retinal OCT scan showed vitero-macular traction and epiretinal membrane in the right eye. He had normal foveal contour in left eye. The patient underwent right eye pars plana vitrectomy with membrane peeling, endolaser and silicone oil. Few weeks later he had penetrating keratoplasty in the same eye. Post operatively his vision with multiple pin-holes in the right eye was fluctuating at 0.05. The patient was referred the contact lens clinic. Atlantis scleral contact lens fitting was done to the left eye. (Boston, XO materials). The patient’s vision with this contact lens reached up to (0.5). This is considered a reasonable good vision that is suitable for driving according to international standards.

Conclusion:  This patient had tectonic grafts and was initially considered legally blind. After his contact lens fitting in the left eye he was able to drive and to lead normal life. This case report shed the light on the importance of scleral contact lenses in management of severe corneal distortions. It also demonstrates that scleral contact lenses can provide reasonable vision even in patients with tectonic corneal grafts.

Abstract

This report describes the case of a young 7-year-old child who presented with a four-month history of raised superior conjunctival lesions in both eyes and subsequently underwent a conjunctival biopsy in the right eye.

 

He was not known to have either of the congenital disorders and subsequent biopsy revealed an epithelium consisting of irregular, ectatic thin-walled channels lined by a bland single layered epithelium which expressed both CD31 and D2-40.

 

No cytokeratin (Cam 5.2) or EMA was expressed in the report. It was concluded that the features highlighted were likely due to an underlying conjunctival haemangioma or lymphangioma.

Romana Fazal, Periocular steroids for macular edema associated with retinal arterio-venous malformation, 29th International Conference on Insights in Ophthalmology; Webinars- June 17-18, 2020

Abstract:

Abstract Retinal racemose hemangiomas are vascular malformations comprising of direct arteriovenous communications in the retina which may sometimes present with defective vision. Exudation and neurosensory detachment are some of the complications which may be responsible for decreased visual acuity. We describe a case of a 38-year-old male presenting with unilateral group II retinal racemose hemangioma complicated with macular edema. Intravitreal bevacizumab was injected after which an increase in edema was noted at one month follow up. He was subsequently treated with posterior sub tenon injection of triamcinolone following which there was a prompt decrease in the intra retinal and subretinal fluid with simultaneous improvement in vision. The visual acuity was maintained and no recurrence was seen till six months after successful treatment.
