However, under emergency conditions in case of unavailability of corneal donor tissue the technique of scleral patch grafts can be used as a decent alternative to corneal patch grafts. The scleral patch graft is equivalently sturdy and provides tectonic/therapeutic bridging over the perforation to help salvage the eye. In this case series, we have described three cases, two of whom had peripheral corneal perforations due to aggressive corneal ulcerations refractory to medical management. The last case had posterior corneal abscess with thinning which was also refractory to treatment; hence, scleral grafting (unavailability of therapeutic corneal graft) was performed to manage the case.","PeriodicalId":33073,"journal":{"name":"Journal of Clinical Ophthalmology and Research","volume":"11 1","pages":"216 - 218"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47378407","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}

Aims: The aim of this study was to assess the role of the Mantoux test in the diagnosis of OTB. Settings and Design: This was a retrospective chart review of patients who were diagnosed to have and treated as OTB in 1 year at our tertiary care center in Western India. Methods: The study population included 34 patients who presented to us and were diagnosed to have OTB, using standards published by the Department of Health Research, Ministry of Health and Family Welfare, Government of India, and the Indian Council of Medical Research. Results: A total of 34 patients were diagnosed to have OTB in the study period of 1 year between January 1, 2021, and December 31, 2021. Of these 34 patients; 14 were male and 20 were female. The Mantoux test had been done in 32/34 patients. It was positive in 26 patients and negative in six patients. Looking specifically at the six patients in whom the Mantoux was negative, apart from having ocular signs of tuberculosis (TB), they had positive findings suggestive of old/active TB on contrast-enhanced chest computed tomography scan. Of the 34 patients, only five patients were treated based only on the clinical signs of OTB with only a positive Mantoux test, but even they all showed a response to treatment. Conclusions: There is a definite role of the Mantoux test when interpreted considering the clinical phenotype and radiology findings in OTB.","PeriodicalId":33073,"journal":{"name":"Journal of Clinical Ophthalmology and Research","volume":"11 1","pages":"194 - 198"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48331124","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}

Introduction: Senile cataract is a leading cause of blindness in India. Cataracts are managed by cataract extraction with implantation IOL. Before surgery, IOL power is calculated by biometry. IOL power calculation is the main key to obtaining a good refractive outcome after cataract surgery. Materials and Methods: A hospital-based study was conducted prospectively to evaluate IOL power using SRK T and HOFFER Q formulae in patients undergoing phacoemulsification with posterior chamber intraocular lens in long eyes over a period of 18 months. Thirty patients were studied based on inclusion criteria. A detailed clinical examination, pre- and postoperative visual acuity, anterior chamber depth (ACD), and refraction were done on day 30 postsurgery. Results: The study included 30 cases with 15 patients in either group, of which 63% were male and 37% were female; 95% of the patients were aged above 50 years; the maximum number of patients in either group had an axial length in the range of 24.5–25 mm; the maximum preoperative ACD was between 3 and 4.5 mm and the maximum postoperative ACD was between 4 and 4.5 mm in both groups; 40% of the patients in either group had 6/6 vision; spherical refractive error postoperative was seen in 73% in the SRK T group and 68% in the HOFFER Q group; and cylindrical refractive error was seen in 27% in SRK T group and 32% in HOFFER Q group. Conclusion: Either formula can be used for IOL power calculation in eyes up to 26.5 mm, as not much difference in postoperative refractive error was observed. Both formulas had a lesser degree of spherical error and an equally good visual outcome postoperatively. Careful biometry is important to prevent postoperative surprises.","PeriodicalId":33073,"journal":{"name":"Journal of Clinical Ophthalmology and Research","volume":"11 1","pages":"158 - 162"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49335933","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}

Aims: The present study was undertaken to analyze the conjunctival surface changes by conjunctival impression cytology (CIC) and correlate them with glycosylated hemoglobin (HBA1c) levels. Settings and Design: Known cases of DM satisfying the inclusion criteria were included in this nonrandomized prospective study, which was undertaken after ethical clearance was obtained from our institutional ethical review board. Subjects and Methods: Eighty patients with DM who presented to the Department of ophthalmology at our center were included in the study; they were divided into Group 1 (HbA1c ≤6.5%) and Group 2 (HbA1c >6.5%). A detailed history, general physical examination, complete ophthalmological examination, and CIC were performed in all of the participants. Statistical Analysis Used: Data were analyzed using Chi-square test and statistical software EPI INFO Version 6 and Microsoft Excel. P < 0.05 was considered statistically significant. Results: CIC technique revealed that, after age and gender adjustment, there was a significantly higher percentage of uncontrolled diabetic patients (77.7%) who had lower goblet cell density and higher Nelson grades of conjunctival squamous metaplasia. This difference was significant for all age groups and both sexes (P < 0.001), and it was also significantly related to the duration of DM. In addition, there was a positive correlation between DR and decreased corneal sensation when associated with poor glycemic control (HbA1c >6.5%). Conclusions: Dry eye disease and ocular surface disorders are increasingly recognized in patients suffering from DM. The ocular surface evaluation must be included in the routine examination of all diabetic patients. CIC is a safe, minimally invasive procedure with no side effects and can serve as one of the diagnostic tools for the evaluation of the ocular surface.","PeriodicalId":33073,"journal":{"name":"Journal of Clinical Ophthalmology and Research","volume":"11 1","pages":"140 - 145"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47295666","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 study is done to assess the incidence of ROP and also to analyze the risk factors involved in the development of ROP in preterm babies between 34 and 36 weeks of gestation. Aims: Risk factor analysis of ROP in late preterm babies. Settings and Design: This is a prospective observational study done in a tertiary-level multispecialty hospital between January 2020 and January 2022. Materials and Methods: Two hundred and eleven preterm babies born between 34 and 36 weeks of gestation were included in the study. Their systemic comorbidities were identified after reviewing their hospital records. They were followed up till their retina reached maturity. Statistical Analysis: It was carried out using SPSS software version 17. Results: The incidence of ROP was 6.2%. Twelve (92.3%) babies belonged to type 2 ROP. All these babies had a spontaneous resolution of ROP and did not require any intervention. One (7.7%) baby born at 36 weeks of gestation with a birth weight of 1.5 kg, presented at 52 weeks of gestation with Stage 5B of ROP in both eyes. Using univariate regression analysis, SGA status, pleural effusion, chylothorax, congestive cardiac failure, congenital diaphragmatic hernia, hypoxic–ischemic encephalopathy, and any intervention were found to be statistically significant. On multivariate analysis, SGA status and hypoxic–ischemic encephalopathy were statistically significant.

Color Doppler imaging is a new method that allows simultaneous two-dimensional anatomical and Doppler evaluation of hemodynamic characteristics of the retinal artery. Aim: The aim of the study is to compare retrobulbar vessel Doppler indices in DR and diabetic with no retinopathy (DNR) using color Doppler sonography. Materials and Methods: A time-limited, hospital-based study was conducted at a tertiary care hospital in Indore, Madhya Pradesh. The study included DR and DNR who were referred from the ophthalmology outpatient department to the radiology. Ophthalmologists performed baseline fundoscopy to categorize patients into different levels of retinopathy severity based on the International disease severity scale proposed by Wilkinson, which has five levels ranging from none to proliferative DR, indicating the risk of progression. Results: In the DR group, 26 (74.25%) patients had hemoglobin A1c (HbA1c) levels ranging from 7 to 7.9 and in the DNR group, 9 (26%) patients had HbA1c levels ranging from 6 to 6.9. Among 35 patients with DR, 25 (71%) patients and 7 (20%) had mild DR and moderate DR, respectively, and only 3 (8%) patients belonged to severe DR. The median resistive index (RI) of the ophthalmic artery in DR and DNR groups was 0.83 and 0.73, respectively. The median RI of the central retinal artery in DR and the DNR group was 0.8 cm/s and 0.6 cm/s, respectively. In the posterior ciliary artery, the median RI was higher in the DR group, i.e. 0.78, compared to the DNR group, i.e. 0.63. As RI depicted increased vascular resistance, it was higher in the DR group than in the DNR group. A weak positive correlation was found between HbA1c and peak systolic velocity, end-diastolic volume, and RI of all three arteries (ophthalmic artery, central retinal artery, and posterior ciliary artery) as inferred from the Spearman's rank correlation coefficient among both groups. Conclusion: Color Doppler ultrasonography can be used to assess these microvascular changes and provides the association between the altered ocular blood flow and the severity of retinopathy. It helps us to predict even before DR appearance, enabling early diagnosis of DR and early intervention.","PeriodicalId":33073,"journal":{"name":"Journal of Clinical Ophthalmology and Research","volume":"11 1","pages":"186 - 189"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46066072","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}

We investigated the knowledge levels of patients on home self-care precautions postdischarge and suggested ways to improve these. Materials and Methods: This cross-sectional study used a random sample from six partner hospitals in north and west India. Patient's knowledge regarding postoperative home self-care was assessed in three domains (i) general eye care precautions (GECP), (ii) eye cleaning procedures (ECP), and (iii) instilling medications in the eye (IME). Data were collected using a structured questionnaire. Results: A total of 616 patients provided interviews and visual acuity (VA) assessments. The median ages were 65 and 63 years for males and females, respectively. Postsurgery, an overwhelming number had either very good or good VA (91.2%). Overall, the knowledge levels were “moderately adequate” for GECP at 57.9%. However, “inadequate” knowledge levels were found pertaining to ECP and IME domains with 69.8% and 84.3%, respectively. With multiple logistic regression, female patients (odds ratio [OR] 2.7, 95% confidence interval [CI] 1.8–4.2) were significantly more likely to have moderate to adequate knowledge of GECP. Those attending both the postoperative review visits were significantly more likely to have moderate to adequate knowledge of ECP (OR 2.4, 95% CI 1.3–4.4) and IME (OR 1.5, 95% CI 0.8–2.7), respectively. Conclusion: Knowledge levels were moderately adequate for GECP, while inadequate for ECP and IME domains, respectively.
