Background: Several studies have demonstrated a correlation between subclinical hypothyroidism (SCH) and diabetic retinopathy (DR) with conflicting results. The study is aimed to find out the correlation and severity of DR with thyroid status. Materials and Methods: A cross-sectional study was conducted taking up 59 patients of DR and categorized them according to the severity of DR as per early treatment DR study classification. Thyroid stimulating hormone (TSH), free thyroxine (FT4), and FT3 concentration were measured in all 59 patients. Patients with normal TSH and FT4 values are euthyroid patients and those with normal FT4 but TSH >4.12 mIU/L is considered having SCH and those with FT4 <0.93 ng/dL and TSH >4.12 mIU/L are considered having hypothyroidism. The severity of DR is compared between the euthyroid, subclinical hypothyroid, and hypothyroid groups. Results: Out of the 59 patients included in the study, 23 (38.98%) were females and 36 (61.01%) were males. Out of 59 cases of DR, 51 (86.44) cases were diagnosed with nonproliferative DR (NPDR) and 8 (13.56%) were diagnosed with PDR. Fifteen had thyroid dysfunction, SCH were seen in 13 patients, two patients had hypothyroidism, and 44 had euthyroid. Fifty-one patients of NPDR and SCH were seen in seven patients, and hypothyroid was present in two patients. In eight patients of PDR, six had SCH. Conclusions: In the present study, the prevalence of SCH among the patients of DR with type 2 diabetes mellitus (DM) was found to be 20.33%. The prevalence of severe NPDR and PDR was higher in patients with SCH compared to euthyroid patients. Therefore, SCH is associated with the severity of DR.

Purpose: The purpose of this study was to analyze age for prescription of presbyopic glasses and factors influencing the frequency of their change. Materials and Methods: This was a hospital-based cross-sectional study conducted on patients presenting to the outpatient department of ophthalmology of a tertiary care center from January 2022 to June 2022. Informed written consent was taken. History regarding near work was obtained and detailed examination was done. Results: Males 293 (58.6%) had more preponderance than females 207 (41.4%). Occupations such as tailors, teachers, drivers, engineers, and welders required early (<40–49 years) need of presbyopic correction and frequent (2–3 times in the span of 10 years) change of glasses. Individuals with short height, lower upper segment: lower segment (US: LS) ratio, and hypermetropia were in need of early presbyopic correction and frequent change of glasses. Conclusion: Factors contributing to early need of presbyopic correction in age ranging from <40 to 49 years were occupations needing near work, short height, lower US: LS ratio, and hypermetropia. Factors contributing to increased frequency of change of glasses were occupations needing near work, normal to taller height, lower US: LS ratio, hypermetropia, and the usage of visual display units.

Orbital foreign bodies are not uncommon but a large wooden foreign body involving ipsilateral orbit, nasal cavity and opposite maxilla is not only rare but potentially vision threatening and can be life threatening too. A 43-year-old gentleman presented with injury to his left eye with a tree branch while riding a motorcycle. Examination revealed a left upper eyelid laceration with a hard wooden foreign body lodged between supraorbital rim and upper eyelid, ipsilateral ptosis and periorbital oedema. CT scan showed a transnasal intraorbital foreign body extending from left orbit medially towards opposite maxilla. Exploration was done under general anesthesia and a large linear wooden foreign body measuring 11.5 x 2 x 1.5 cm3 was removed from left orbit without any evidence of damage to vital structures. This is one of the largest reported intraorbital wooden foreign body to the best of our knowledge, hence the report.
眼眶异物并不罕见，但涉及同侧眼眶、鼻腔和对面上颌骨的大型木制异物不仅罕见，而且可能威胁视力，也可能危及生命。一名43岁的男子在骑摩托车时左眼被树枝砸伤。检查发现左上眼睑撕裂，眶上缘和上眼睑之间有一个坚硬的木制异物，同侧上睑下垂和眶周水肿。CT扫描显示一个经鼻眶内异物从左眶内侧向上颌骨延伸。在全身麻醉下进行探查，在没有任何重要结构损伤证据的情况下，从左眼眶取出一个尺寸为11.5 x 2 x 1.5 cm3的大型线性木制异物。据我们所知，这是报告的最大的眶内木制异物之一，因此这份报告应运而生。

Purpose: The prevalence of Vitamin A deficiency (VAD) is the highest in India among the South Asian countries. Suspected causes for this are insufficient dietary intake, lack of education, and a poor monitoring and surveillance system. Awareness regarding VAD is a must, especially among the parents of preschool children who are the most susceptible to its adverse effects. We aimed to assess the knowledge of Vitamin A, analyze awareness of its deficiency, and study the practice of prophylaxis against VAD among the parents of preschool children. Materials and Methods: This cross-sectional study involved 385 participants (Cochran's formula). Guardians or parents of children in the preschool age group were included. A scoring system was applied to the questionnaire distributed to each participant to objectively assess the answers. Results: 243/385 (63.12%) of the participants had heard of Vitamin A. Of those who had heard of the vitamin, 111/243 (45.68%) were not aware of a single source of Vitamin A. The mean score obtained for the assessment of VAD was 3.29/11, which indicates a low score. Section B assessed the knowledge on VAD, and the mean score obtained was 3.29/11. All 385 respondents were assessed on the consumption of Vitamin A-rich foods. Of these, 160 (41.56%) demonstrated an average practice, or a score between 7 and 10. Very good practice was demonstrated by only 18 (4.68%). Conclusion: Overall, a low level of awareness of Vitamin A and its deficiency exists among the population. Despite this, an average practice of Vitamin A food consumption was demonstrated.

A 56-year-old female patient presented with vision loss in right eye (OD) for the past 6 months with whitish discoloration of the eye; the patient underwent therapeutic keratoplasty 1 year back elsewhere, and was on treatment with topical fortified antibiotics, lubricants, and antiglaucoma medications for 6 months. On examination, a chalky white opacified graft was noted, simulating scleral tissue transplant with edematous vascularized host corneal tissue. Corneal scraping was positive for fungal elements on potassium hydroxide mount, and culture on Sabouraud agar reported hyalohyphomycetes growth. Therapeutic keratoplasty was performed, and histopathological evaluation (HPE) revealed corneal tissue with areas of necrosis, karyorrhectic debris with mixed inflammatory cell infiltrate, and dystrophic calcification in the stroma.

Purpose: The purpose of this study was to compare the psychosocial impact of squint on children with that on adult patients in India. Materials and Methods: In this descriptive cross-sectional study, a twenty-question quality-of-life instrument ASO-20 was administered to patients with strabismus to study the psychosocial impact of strabismus on them. The results were compiled in an Excel sheet and analyzed statistically. Results: Thirty-two children (5–18 years) and 24 adults (>18 years) were included in the study. It was observed that all the adults responded that they always noticed that they have strabismus as against significantly less (81.25%) number of children who did so. Similarly, 75% of adults responded that strabismus affected their relations with other people, whereas only 37.5% of children felt that strabismus affected their relations with other people. While 95.83% of adults felt that opportunities (social interaction or at work) were fewer because of strabismus, only 37.5% of the children felt so. Similarly, while all the adults responded that they frequently imagined that other people were thinking about their eyes, only half of the children (56.25%) felt so. The difference is statistically significant. Significantly more (83.3%) adults responded that they had more difficulty in making friends because of strabismus, as against this, only one-fourth (25%) of the children felt so. The difference is statistically significant. Both the groups felt that strabismus bothered them, people noticed strabismus while interacting with them and they felt different (inferior) because of strabismus. Although the percentage who felt so was more in adults as compared to children, the difference was not statistically significant. Similarly, more children (75%) said that strabismus never hindered their performance as compared to adults (66.67%), however, the difference was not statistically significant. Conclusions: Strabismus has negative psychosocial effects on the affected individual which intensify with age.

Purpose: To study and compare the macular visual functions among the subjects with and without risk for Obstructive Sleep Apnea Syndrome. Methods: Prospective case–control study involving 20 cases and 17 controls. Subjects were classified as cases with the presence of snoring and controls in the absence of it. Cases were administered with a standardized Berlin Questionnaire and were grouped as high risk and low risk based on their scores. Color discrimination, contrast sensitivity, and photo stress recovery test were measured following a comprehensive eye examination. Body mass index and neck circumference were also measured. Results: There were 13 subjects in the high-risk category, 7 subjects in the low-risk category, and 17 subjects in the control group. The total error score in color discrimination was significantly different among high risk (112 ± 84.17), low risk (74 ± 43.98), and controls (56 ± 39.43) (P = 0.04) whereas, contrast sensitivity (P = 0.897), visual acuity (P = 0.95), and photo stress recovery test (P = 0.32) did not show any significant difference. Conclusion: High-risk category subjects showed poor color discrimination than controls hence, these individuals must undergo a detailed ophthalmic examination with a color discrimination test and must be evaluated in a sleep clinic.

The purpose of this study is to describe the scleral fixation of intraocular lens (IOL) using the IOL flange technique combined with penetrating keratoplasty. The technique is a modification over the previous Yamane's transconjunctival double-needle flanged-haptic technique of intrascleral fixation of IOL as it involves the use of 5-0 prolene suture to create an IOL flange, and the IOL is placed in the sulcus. With this technique, there are less chances of haptic and vitreous drag as compared to the previously described techniques. This combined procedure is easy to learn, execute and economical with additional advantage of added IOL stability and can be of great benefit for patients with aphakia and no posterior capsular support.
