{"title":"Does dropout happen even with patients fitted with contact lenses for irregular cornea?","authors":"Sona Paul","doi":"10.25259/ihopejo_6_2023","DOIUrl":"https://doi.org/10.25259/ihopejo_6_2023","url":null,"abstract":"Objectives: Different types of contact lenses play a primary role in improving visual acuity in irregular corneas. Although there are multiple evidences for vision improvement with contact lens patients still drop out of lens wear and choose other methods of treatment, surgeries, or discontinue the lenses. Materials and Methods: Three thousand two hundred patients who were evaluated for 5 years at a specialty contact lens clinic in a tertiary eye care center, but did not return to the clinic for over 18 months from the date of dispensing were identified as dropouts. Only 73 patients were identified as falling under this category of dropout. The reasons for dropout were categorized as comfort-related, vision-related, other reasons, and those who underwent surgical procedures. Results: Unlike previous studies, which included soft lenses, this study revealed only 2.28% (73/3200) of dropouts. There were 38 patients with unilateral lens fitting and 35 patients with bilateral lens fitting. The visual acuity was significantly improving with contact lens in these eyes. The clinical presentation of these patients was analyzed to know about their stage of disease while they dropout from the contact lens clinic. Conclusion: Although dropout of contact lens is much lesser in irregular corneal conditions, it is important for the practitioner to be updated with the alternate and latest modality of lens choices to satisfy vision-related and comfort-related issues of patients.","PeriodicalId":176313,"journal":{"name":"IHOPE Journal of Ophthalmology","volume":"75 6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135884386","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}

{"title":"Direct healthcare cost and barriers to the medical management of primary open-angle glaucoma in healthcare facilities in Yaounde – Cameroon","authors":"Christelle Domngang, Paola Maguib, Chantal Nanfack Ngoune, Yimta Foutse, Giles Kagmeni","doi":"10.25259/ihopejo_16_2023","DOIUrl":"https://doi.org/10.25259/ihopejo_16_2023","url":null,"abstract":"Objectives: The objective of this study was to estimate the direct healthcare cost of glaucoma among patients attending two healthcare services in Yaounde, Cameroon. Materials and Methods: This investigation was a hospital-based, observational, and cross-sectional study of 122 glaucoma patients on follow-up from January to August 2021. The study was carried out using a pre-tested questionnaire and analyzed sociodemographic and clinical characteristics, monthly income, investigations performed, medications prescribed, and direct healthcare costs. Data were analyzed using the Statistical Package for the Social Sciences version 24. Results: A total of 122 glaucoma follow-up patients participated in the study of whom 73 (59.9%) were male (sex ratio M/F = 1.49). Seventy-one (58.19%) participants were above 60 years. The majority (67.4%) had a higher education level. Over 40% of participants reported a monthly income of <228 Euros. Only 38 (31.1%) had health insurance. During the study year, each patient underwent 2.25 ± 0.84 consultations, 2.76 ± 1.40 ocular pressure measurements, 0.73 ± 0.52 visual field examinations, and 0.32 ± 0.2 gonioscopy. Prostaglandin analogs were the most widely prescribed drugs (71%), followed by β-blockers (Carteolol and Timolol) and carbonic anhydrase inhibitors with frequencies of 62% and 15%, respectively. The direct medical cost of the study population was estimated at 468.47 ± 155.34 Euros. The greatest proportion of out-of-pocket expenses (61.13% of medical costs) concerned the purchase of drugs, with an average cost of 284.16 ± 115.25 Euros. Patients treated in the public sector spent an average of 425.78 ± 38.49 Euros, while those treated in the private sector spent 562.22 ± 139.18 Euros during the study year ( P = 0.001). However, health coverage and type of glaucoma did not influence the direct cost of treatment. The main obstacles to glaucoma care were insufficient income followed by forgetfulness. Conclusion: The present study shows that almost all participants self-funded their glaucoma management. More than 60% of the direct healthcare cost was devoted to anti-glaucoma drugs and the main barrier to optimal glaucoma care was the lack of financial resources. All stakeholders need involvement, especially health policymakers, to prioritize glaucoma management to make it affordable for patients.","PeriodicalId":176313,"journal":{"name":"IHOPE Journal of Ophthalmology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135823592","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}

Recruiting a variety of members (including patients or carers) with the required content expertise and experience to contribute to discussions on the guideline topic. Recruiting a chair who has experience in committee facilitation is likely to be broadly accepted by all in the committee and can guide and lead them through the guideline development process.

Materials and Methods: This was a cross-sectional and observational study. This was a cross-sectional study, in which 30 eyes of each group and controls were studied, CDI was done by a single observer for all cases. Peak systolic velocity (PSV), end-diastolic velocity (EDV), and resistive index (RI) were calculated for OA, CRA, and PCA. Visual fields and retinal nerve fiber layer (RNFL) analysis were done. Results: PSVs and EDVs were lower and RIs were higher for CRA and PCA of NTG and POAG compared to those of controls. The severity of glaucoma (visual field defect) increased when RI of OA was increased in NTG. No such relationship was established between RNFL thinning and OBF. Conclusion: Reduction in PSV and EDV leads to increased RI which is one of the contributory factors in the functional damage in NTG.","PeriodicalId":176313,"journal":{"name":"IHOPE Journal of Ophthalmology","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135883064","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}

Materials and Methods: A school-based descriptive study using a multistage sampling technique was carried out for 4 months. The visual acuity of the pupils was checked using a non-illuminated Snellen’s chart at 6 m, assessing one eye at a time. Individuals with visual acuity worse than 6/12 had pinhole tests and refraction done. Statistical analysis was done using Statistical Package for the Social Sciences version 20 and frequencies, simple percentages, and Chi-square were used to compare proportions. Results: A total of 400 participants were seen during the study, out of which 84 participants had vernal keratoconjunctivitis. Of these, 51 (60.7%) had refractive errors. Astigmatism was the most common form of refractive error seen in our study 26 (31%), myopia was seen in 15 (17.9%) whereas hypermetropia was the least seen in 10(11.9%). Simple astigmatism was seen more in individuals with acute stage of VKC 9 (75.0%) whereas compound astigmatism was commonly seen in participants with chronic stage of VKC (42.9%).
