Background: Visual impairments and age-related eye diseases need to be detected and treated in a timely manner. However, this is often hampered by lack of appropriate medical equipment. We have invented a portable, recordable, and smartphone-attachable slit-lamp device, called the Smart Eye Camera (SEC). The aim of this study was to compare evaluating nuclear cataract (NUC) between the SEC and the conventional, non-portable slit-lamp microscope. Methods: A total of 128 eyes of 64 Japanese patients (mean age: 73.95 ± 9.28 years; range: 51‒92 years; female: 34) were enrolled. The NUC was classified into four grades (grade 0 to 3) based on three standard photographs of nuclear opacities according to the WHO classification by ophthalmologists. An ophthalmic healthcare assistant (non-ophthalmologist) filmed the eyes in video mode by the SEC and an ophthalmologist graded the NUC. Grade correlation and inter-rater reproducibility were determined. Results: NUC grading by the two approaches correlated significantly (both eyes: r = 0.871 [95%CI: 0.821 to 0.907; p < 0.001]). Inter-rater agreement was high (weighted κ = 0.807 [95%CI: 0.798 to 0.816; p < 0.001]). Conclusions: This study suggests that the SEC is as reliable as the conventional non-portable slit-lamp microscope for evaluating NUC.

Background: To review cases of posterior segment eye diseases (PSEDs) seen at the Eye Foundation Centre Ijebu, Nigeria in a 5 year period for planning purposes.Methods: Data was collected from patients’ case notes from January 2006 to December 2011. A systematic sampling of 468 patients from 1173 case notes of patient with (PSEDs) was done. Information retrieved was: age, sex, state of residence and diagnosis. All patients were examined by the glaucoma and the vitroretinal specialist as the case may be. They had visual acuity, refraction, slit lamp examination (including intraocular pressure (IOP) with Goldman applanation tonometer), and dilated fundoscopy with (bilateral indirect ophthalmoscopy) BIO, slit lamp using 20 D, 78 D and 90 D respectively. The glaucoma patients in addition had central visual field (CVF), Central cornea thickness (CCT), fundus photograph and in some cases optical coherence tomography (OCT) done in addition to the above.Results: The mean age was 59.98 years (SD 17.67) and the age range is 5-95 years. Males outnumbered females by 63% to 37%. The diseases were more common in age group 61 to 80. Patients’ attendances were mostly from Ijebu division of Ogun state (57%). Glaucoma is the commonest cause of attendance 262 (56%) followed by diabetic retinopathy 29 (6.2%) and age-related macular degeneration (ARMD) 28 (6.0%).Conclusions: Glaucoma, diabetic retinopathy and ARMD were noted as the commonest PSEDs in Ijebu division in Southwestern Nigeria.

Background: The incidence of allergic conjunctival diseases (ACDs) is gradually increasing worldwide. Both ophthalmologists and non-ophthalmologists prescribe eye drops to treat ACDs; however, there are many cases which are treated without sufficient examination and diagnosis of the eyes. We have invented a portable, recordable, and smartphone-attachable slit-lamp device—Smart Eye Camera (SEC). The purpose of this study was to compare the diagnostic abilities of ACDs between the SEC and the conventional, non-portable slit-lamp microscope. Methods: This prospective observational study included 32 eyes of 17 Japanese patients (mean age: 21.5 ± 14.8 years; range: 11–51 years; female: 5). The severity of 10 objective signs in the palpebral conjunctiva, bulbar conjunctiva, limbus, and cornea were scored on a grading scale of 0 to 4 (0 = normal; 1+ = mild; 2+ = moderate; 3+ = severe), respectively. First, the conventional slit-lamp microscope was used to examine the grade of the ACDs. Second, another ophthalmologist filmed the eyes using the SEC and two other ophthalmologists evaluated the grades on another day. The correlation and inter-rater reproducibility in total scores among the two devices were determined. Results: Total scores of clinical signs, evaluated by the two approaches, correlated significantly (both eyes: r = 0.918 (95% CI: 0.839 to 0.959; p < 0.001)), with substantial inter-rater agreement (weighted κ value = 0.631 (95% CI: 0.601 to 0.661; p < 0.001)). Conclusions: The SEC is as reliable as the conventional non-portable slit-lamp microscope for assessing ACDs.

Background/Objective:: The aim of this systematic review is to identify all the available data on human lens proteomics with a critical role to age-related cataract formation in order to elucidate the physiopathology of the aging lens. Materials and Methods:: We searched on Medline and Cochrane databases. The search generated 328 manuscripts. We included nine original proteomic studies that investigated human cataractous lenses. Results:: Deamidation was the major age-related post-translational modification. There was a significant increase in the amount of αA-crystallin D-isoAsp58 present at all ages, while an increase in the extent of Trp oxidation was apparent in cataract lenses when compared to aged normal lenses. During aging, enzymes with oxidized cysteine at critical sites included GAPDH, glutathione synthase, aldehyde dehydrogenase, sorbitol dehydrogenase, and PARK7. Conclusion:: D-isoAsp in αA crystallin could be associated with the development of age-related cataract in human, by contributing to the denaturation of a crystallin, and decreasing its ability to act as a chaperone. Oxidation of Trp may be associated with nuclear cataract formation in human, while the role of oxidant stress in age-related cataract formation is dominant.

AbstractThe purpose of this study was to report the incidence of elevated intraocular pressure (IOP) after intravitreal injection (IVI) of anti-vascular endothelial growth factor (VEGF) in Japanese patients with age-related macular degeneration (AMD). A retrospective study of chart review of patients who underwent ≥ 10 intravitreal anti-VEGF injections between April 2009 and December 2019 was conducted. Elevated IOP was defined as IOP ≥ 25 mmHg at one visit. Cases with elevated IOP resulting from IVI were identified. Furthermore, the association between elevated IOP and some parameters, as the risk factors that influence elevated IOP, was investigated. A total of 402 eyes of 370 patients were included in this study. Twenty-eight eyes of 26 patients (7.0%) were identified as cases with elevated IOP after IVI. The mean time of elevation after baseline was 50.6 ± 26.5 months. History of glaucoma (p = 0.021; odds ratio, 5.85), treatment modality (p = 0.019; odds ratio, 6.32), and total number of injections (p = 0.003; odds ratio, 1.03) were significantly associated with elevated IOP. A late complication of elevated IOP is associated with IVI in patients with AMD. Particularly, history of glaucoma and treat and extend regimen with frequent injections were found to be risk factors of elevated IOP.

The Impact

Objective: To compare the vision-targeted health related quality of life (HRQOL) between neuro-ophthalmological patients and other eye diseases by the National Eye Institute 25-Item Visual Function Questionnaire. Methods: Cross sectional study with a control group and patients with the following pathologies: primary open-angle glaucoma (POAG), diabetic retinopathy (DR), age-related macular degeneration (ARMD), non-arteritic ischemic optic neuropathy (NAION), intracranial hypertension (IH), optic neuritis (ON), ptosis and cataract. Results: All comparisons of the subscales scores among the control group and the patient groups were statistically significant (p<0.05) except for “ocular pain” (p=0.160), “social functioning” (p=0.052) and “peripheral vision” (p=0.112). The control group had the best scores across all dimensions of the NEI VFQ-25. Interestingly, the ARMD and cataract groups presented the best and worst total scores of NEI VFQ-25, respectively. The lowest subscales scores were found in the cataract, in the NAION/ON, and in the POAG groups. Finally, the comparison between the NAION/ON/IH patients and the other eye diseases did not show statistical significance in any subscale. Conclusion: The NEI VFQ-25 showed the impact of various eye conditions in vision-targeted HRQOL, and no difference was measured between neuro-ophthalmological patients and other eye diseases
