Neha Singh, Jolly Rohatgi, Ved Prakash Gupta, Vinod Kumar Department of Ophthalmology, University College of Medical Sciences, Delhi, India Purpose: To study whether there is a difference in central macular thickness (CMT) and peripapillary retinal nerve fiber layer (RNFL) thickness between the two eyes of individuals having anisometropia >1 diopter (D) using spectral domain optical coherence tomography (OCT).Material and methods: One hundred and one subjects, 31 with myopic anisometropia, 28 with astigmatic anisometropia, and 42 with hypermetropic anisometropia, were enrolled in the study. After informed consent, detailed ophthalmological examination was performed for every patient including cycloplegic refraction, best corrected visual acuity, slit lamp, and fundus examination. After routine ophthalmic examination peripapillary RNFL and CMT were measured using spectral domain OCT and the values of the two eyes were compared in the three types of anisometropia. Axial length was measured using an A Scan ultrasound biometer (Appa Scan-2000).Results: The average age of subjects was 21.7±9.3 years. The mean anisometropia was 3.11±1.7 D in myopia; 2±0.99 D in astigmatism; and 3.68±1.85 D in hypermetropia. There was a statistically significant difference in axial length of the worse and better eye in both myopic and hypermetropic anisometropia (P=0.00). There was no significant difference between CMT of better and worse eyes in anisomyopia (P=0.79), anisohypermetropia (P=0.09), or anisoastigmatism (P=0.16). In anisohypermetropia only inferior quadrant RNFL was found to be significantly thicker (P=0.011) in eyes with greater refractive error.Conclusion: There does not appear to be a significant difference in CMT and peripapillary RNFL thickness in anisomyopia and anisoastigmatism. However, in anisohypermetropia inferior quadrant RNFL was found to be significantly thicker. Keywords: RNFL, CMT, anisometropia, amblyopia

Context : Visual disability in India is categorized based on severity. Sometimes the disabled person does not fit unambiguously into any of the categories. Aims : To identify and quantify disability that does not fit in the current classification, and propose a new classification that includes all levels of vision. Settings and Design : Retrospective chart review of visual disability awarded in a teaching hospital. Materials and Methods : The last hundred records of patients who had been classified as visually disabled were screened for vision in both eyes and percentage disability awarded. Data were handled in accordance with the Helsinki Declaration. Results : Twenty-one patients had been classified as having 30% disability, seven each had 40% and 75%, and 65 had 100% disability. Eleven of them did not fall into any of the current categories, forcing the disability board to use its own judgment. There was a tendency to over-grade the disability (seven of 11; 63.6%). The classification proposed by us is based on the national program for control of blindness′ definition of normal vision (20/20 to 20/60), low vision ( < 20/60 to 20/200), economic blindness ( < 20/200 to 20/400) and social blindness ( < 20/400). It ranges from the mildest disability (normal vision in one eye, low vision in the other) up to the most severe grade (social blindness in both eyes). Conclusions : The current classification of visual disabilities does not include all combinations of vision; some disabled patients cannot be categorized. The classification proposed by us is comprehensive, progresses logically, and follows the definitions of the national program.

Purpose: To study the prevalence, manifestations and severity of ocular involvement in Indian patients with Behcet′s disease. Method: Prospective analysis of all patients of suspected Behcet′s disease between 1997 and 2001. Results: A total of 19 patients were diagnosed to have Behcet′s disease. Ocular manifestations were seen in 36% patients. The commonest manifestation was conjunctival ulcer (26.3%), followed by iridocyclitis (10.5%). None of the patients had posterior segment involvement or visual loss. Response to topical corticosteroids was good. Conclusion: The prevalence and severity of ocular lesions in Behcet′s disease is relatively low in Indian patients. Conjunctival ulcers was a common finding, which is rarely reported in the world literature.

160 Patients of leprosy with or without visual disability were submitted to various surgical procedures as prophylatic or curative measures The various procedures undertaken included cataract surgery, ectropion correction, trabeculectomy tarsorrhaphy and kerato-plasty. The utility of repositioning of pupil achieved by xenon arc photocoagulation for cases of centrally situated corneal opacity has been introduced with encouraging results Such a procedure is of particularly benefit in patients who are poor risk for keratoplasty. Surgery in leprosy offers a new hope to patients with advanced ocular complications due to this crippling disease.

Purpose: Rhino-orbital-cerebral mucormycosis (ROCM) is the most common presentation of mucormycosis. Sinonasal-orbital debridement with exenteration is a life-saving procedure in ROCM patients in view of severe involvement of sinuses and the eyeball. Following the second wave of coronavirus disease 2019 (COVID-19), there was a massive surge in mucormycosis cases in India in post-COVID-19 patients. Of over 300 cases of mucormycosis admitted in our hospital, many underwent exenteration and these specimens were evaluated histopathologically, where fat necrosis was found to be a prominent finding. The spectrum of fat necrosis in ROCM in orbital fat has not been described in literature. Hence, we sought to evaluate the significance and spectrum of orbital fat necrosis in ROCM., Methods: This 3-month retrospective study included 15 cases of ROCM which underwent exenteration. Clinical data, radiologic details, and histopathologic findings were tabulated. Sections were also subjected to Periodic acid Schiff (PAS) and Gomori's methenamine silver (GMS) stains for confirming the fungus., Results: All 15 cases showed fat stranding on computed tomography (CT) scan. On histopathologic examination, various tissue reaction patterns observed included acute/chronic inflammatory infiltrate, suppurative granulomas with giant cells, coagulative and fat necrosis, broad aseptate fungal hyphae with or without angioinvasion, and neural invasion. Fungal hyphae were confirmed with PAS and GMS stains. The spectrum of fat necrosis observed in all the cases included 1) acute necrotizing fat necrosis, 2) ghost adipocytes with or without saponification, and 3) crystalline/gouty fat necrosis., Conclusion: Fat necrosis is a significant finding in ROCM, both on CT scan and histopathology. All three patterns of fat necrosis may be observed simultaneously in a case of ROCM., (Copyright © 2024 Copyright: © 2024 Indian Journal of Ophthalmology.)

Purpose: To study the efficacy of low dose atropine (0.01%) eye drops in preventing myopia progression in children by comparing the mean change in spherical equivalent (diopter) and axial length (mm) over a period of one year to a control group and study its effect on near vision, pupil size, keratometry and pachymetry., Methods: 200 eyes of 100 myopic children were randomized into two groups based on a computer-generated random number table. The treatment group was administered 0.01% atropine eye drop once at bedtime and control group was administered a placebo. The follow up was done 3-monthly for 12 months by assessing the mean change in spherical equivalent and mean change in axial length. Other parameters like near vision, pupil size, keratometry and pachymetry were assessed at each follow up., Result: The study was age and sex matched. The mean change in spherical equivalent refraction and axial length was significantly lower in the treatment group (0.31 ± 0.55 D; 0.11 ± 0.22 mm) than the placebo group (0.80 ± 1.65 D; 0.23 ± 0.44 D) ( p -value: 0.003). Less steepening of the corneal curvature was observed in the treatment group (0.16 ± 0.28 D vs 0.29 ± 0.3 D; p  < 0.001) and the mean change in pachymetry was comparable between the groups (0.00 ± 0.01) ( p -value 0.489). No significant change was seen in near vision (96% of the eyes with atropine had no change in near vision; 2% of the eyes had a change of near vision by one line ( p -value 0.500); 2% had a change by 3 lines ( p -value: 0.07) or pupil size following treatment., Conclusion: The use of 0.01% atropine eye drop reduced the progression of myopia over the study period of one year with no significant changes in near vision, pupil size. No patient reported any systemic and local side effects with administration of 0.01% atropine eye drop.

Purpose: TO report the corneal manifestations in patients with COVID-19-associated rhino-orbito-cerebral mucormycosis (ROCM)., Methods: This study was a retrospective, observational, and record-based analysis of patients of ROCM with corneal involvement., Results: A total of 220 patients were diagnosed with ROCM over a period of 3 months. Thirty-two patients had developed corneal manifestations. The mean age at diagnosis was 52.84 ± 12.8 years. The associated risk factors were systemic mucormycosis, uncontrolled diabetes, recent COVID-19 infection, and injudicious use of systemic steroids. Twenty-nine patients were known diabetics, 32 had recent COVID-19 infection, and 13 gave a history of injudicious use of steroids. The right eye (RE) was affected in nine patients, the left eye (LE) in 20 patients, and both eyes in three patients. Nine patients had a round-oval corneal ulcer. One patient each had a perforated corneal ulcer with uveal prolapse, sealed perforated corneal ulcer, spontaneously healed limbal perforation, diffuse corneal haze with hyphemia, panophthalmitis, diffuse corneal stromal abscess, limbal ischemia, anterior uveitis with posterior synechiae, inferior corneal facet, and filamentary keratitis. Three patients each had a corneal melt and inferior conjunctival xerosis with chemosis. Orbital exenteration was performed in six patients. Five patients with corneal ulcers healed. Topical eye drops of amphotericin (0.5 mg/ml) cycloplegic, antiglaucoma medications, and lubricant eye drops were started along with systemic antifungals., Conclusion: Central corneal ulcer was the most common manifestation of mucormycosis. A concentration as low as 0.5 mg/ml of amphotericin eye drops was effective in the treatment.

Rhino-orbital cerebral mucor mycosis is a rare disease entity, where retinal involvement is described in the literature mostly as CRAO. However, pathological studies have shown mucor invading the choroid and retina with a neutrophilic reaction. So, it is pertinent that retinal inflammation secondary to invading mucor has some role in microstructural changes seen in the vitreous and retina of these patients. This novel study aims to describe the vitreal and retinal features of patients with vision-threatening rhino-orbital cerebral mucor mycosis and how they evolve on spectral domain optical coherence tomography (SD-OCT). This study shall also provide insight into the pathophysiology of these vitreoretinal manifestations by in vitro analysis of the exenterated orbital content. Fifteen eyes of fifteen patients with vision-threatening ROCM treated with standard care were enrolled in this study and underwent complete ophthalmic examination, serial colour fundus photography, and SD-OCT for both qualitative and quantitative analysis, at baseline and follow-up visits. SD-OCT on serial follow-up revealed thickening and increased inner-retinal reflectivity at presentation followed by thinning of both, other features such as the loss of the inner-retinal organized layer structure, external limiting membrane (ELM) disruption, necrotic spaces in the outer retina, and hyperreflective foci. Vitreous cells with vitreous haze were also seen. There was a significant reduction in CMT, inner and outer retinal thickness, total retinal thickness (all p < 0.05) with time, the quantum of reduction concentrated primarily to the inner retina. In summary, in vivo and in vitro analysis revealed that early microstructural changes were primarily a result of retinal infarctions secondary to thrombotic angioinvasion. With the late microstructural changes, there was possible sequelae of retinal infarction with some contribution from the inflammation, resulting from mucor invading the choroid and retina., Competing Interests: The authors declare no conflict of interest.

Purpose: To describe a novel approach of subconjunctival injection of mitomycin C (MMC) at the end of trabeculectomy and compare it with intraTenon MMC injection., Methods: This pilot study included 40 eyes of 40 patients with uncontrolled primary and secondary glaucoma. Patients below18 years and failed trabeculectomy were excluded. Patients were randomly allocated into groups A and B (20 patients each). Group A patients received subconjunctival MMC injection in the superonasal quadrant at the end of standard trabeculectomy. Group B received an intraTenon MMC injection before the initial conjunctival incision. Outcome measures included intra-ocular pressure (IOP) reduction, bleb morphology, and complication rates. The complete success was defined as an IOP of ≤21 mmHg without antiglaucoma drugs., Results: The mean preoperative IOP of 46.00 ± 11.2 mmHg in group A and 43.05 ± 10.3 mmHg in group B reduced to 12.00 ± 2.41 mmHg (P ≤ 0.001) in group A and 13.65 ± 2.76 mmHg in group B (P ≤ 0.001) at last follow-up. Complete success was 95% and 75% in groups A and B, respectively, 19 months after surgery. Avascular microcystic blebs (70% of group A and 45% of group B) were more common than avascular white blebs (15% in group A and 35% in group B). No intraoperative complications were seen. Postoperative wound leak, hypotony, choroidal detachment, or endophthalmitis were not encountered in any group., Conclusion: A novel approach of subconjunctival MMC application during trabeculectomy is reported. Both approaches appear to be highly effective in reducing IOP in primary and secondary glaucoma with similar safety profiles and bleb morphology. Subconjunctival MMC yielded a greater success rate (95%) compared to the intraTenon MMC group (75%)., Competing Interests: None

Purpose: To compare surgical success (cosmetic, anatomical & functional) of 'W' shaped incision versus tear-trough incision in external dacryocystorhinostomy (eDCR)., Methods: In a prospective study (November 2018 - March 2020), 61 eyes of chronic dacryocystitis underwent eDCR randomized into group T (30 eyes) & group W (31 eyes). The functional and objective cosmetic assessment was done at 3 months using Munk's and Devoto's scores respectively. The subjective cosmetic evaluation was done using a questionnaire. Grades 0-1 were considered the cosmetic and functional success after assessing the respective scores. The patent lacrimal passage was defined as anatomical success., Results: Mean age was 40.1 ± 14.9 years with female preponderance. Intraoperative skin flap button-holing & reversible darkening of their apices were specific complications of Group W. In the early postoperative period, lid edema & epiphora were significantly more in group T ( p < 0.05). The functional success rate in group T and W was 93.3% and 93.5%, respectively ( p = 0.53). There was a 100% anatomical success rate in group T whereas 96.8% in group W ( p = 0.51). The subjective cosmetic success rate was 83.3% in group T and 80.6% in group W ( p = 0.78) while objective cosmetic success rate was 63.3% and 67.7% in group T and group W, respectively ( p = 0.72)., Conclusion: Surgical success in terms of cosmetic, anatomical & functional outcomes of W-shaped incision were comparable to the conventional Tear trough incision.

Introduction: Rhino-orbito-cerebral-mucormycosis (ROCM) is the most common form of mucormycosis observed during the second wave of COVID-19 where a steep rise in the number of cases was seen. The orbital form is almost always associated with fungal sinusitis. Among the various treatment modalities available, the role of retrobulbar Amphotericin-B injections is under-reported. This study is conducted to determine the role of transcutaneous retrobulbar amphotericin-B (TRAMB) in the management of COVID-19 associated ROCM., Methods: a retrospective analysis of 61 patients of COVID-19 associated ROCM was done, who met the inclusion criteria and presented to a tertiary care center, between May to August 2021. These patients were administered TRAMB (deoxycholate/emulsion form) along-with systemic amphotericin B. All the patients were evaluated for clinical improvement., Results: out of 61 patients, 58 (95.08%) showed overall improvement. 40 patients (65.57%) stabilized or improved clinically and 3 patients succumbed to the illness due to advanced systemic mucormycosis and acute kidney failure. Sixteen out of 58 patients underwent orbital exenteration. Out of remaining 43 patients, 35 showed complete recovery of orbital and ocular disease and the disease stabilized in eight patients. Seven patients demonstrated TRAMB associated ocular complications which however completely resolved in six patients., Conclusion: to the best of the author´s knowledge, regression of orbital mucormycosis with improvement in ptosis, proptosis, ocular motility and stabilization of visual acuity are scarcely reported in literature. Further TRAMB as a globe non-deforming treatment modality is an option available for ROCM., Competing Interests: The authors declare no competing interests., (Copyright: Rekha Yadav et al.)

Aims: Varying prevalence of individual diabetes related vascular complications in prediabetes has been reported. However, very few studies have looked at both macrovascular and microvascular complications in prediabetes., Methods: Study subjects without any history of diabetes underwent oral glucose tolerance test (OGTT) and were classified as either normal glucose tolerance (NGT), prediabetes (PD), newly detected diabetes mellitus (NDDM) on the basis of American Diabetes Association (ADA) criteria. Age and sex matched known diabetes mellitus (KDM) patients were also recruited. All the participants were subsequently screened for both macrovascular (CAD, CVA,PVD) and microvascular (retinopathy, nephropathy and neuropathy)complications of diabetes., Results: Prevalence of vascular complications among prediabetes subjects was 11.1% as compared to 1.4% among NGT subjects, 13.9% among NDDM subjects and 23.8% among KDM subjects. There was no significant between complication rates in prediabetes and NDDM group (p = 0.060). The prevalence of macrovascular and microvascular complications among prediabetes subjects was 4.2% and 6.9% while the same in NDDM was 4.2% and 9.7%., Conclusions: The proportion of subjects with prediabetes and vascular complications was about half of those with known diabetes and almost similar to those with newly detected diabetes mellitus., Competing Interests: Declaration of competing interest We declare that there are no Conflicts of interest to report regarding this manuscript., (Copyright © 2021 Diabetes India.

Purpose: This study aimed to report the comparison of recurrence rate and complications of intrapterygial injection of mitomycin C (MMC) 1 month before bare sclera excision of pterygium with and without conjunctival flap from the inferior bulbar conjunctiva., Methods: This prospective interventional study enrolled 60 patients of pterygia from November 2010 to June 2012. All eyes received 0.1 ml (0.02%) of intrapterygial MMC injection 1 month preoperatively. Patients were divided into two groups of 30 each: Group 1 - bare scleral excision (BSE) and Group 2 - BSE with conjunctival flap from the inferior bulbar conjunctiva to cover the bare sclera. Chi-square test, Fisher's exact test, and unpaired t -test were used for statistical analysis., Results: The mean age was 40.6 ± 12.8 years and 36.9 ± 10.9 years in Group 1 and 2, respectively, ( P = 0.2329). There were 11 (36.7%) males and 19 (63.3%) females in Group 1 and 7 (23.3%) males and 23 (76.7%) females in Group 2 ( P = 0.101). The recurrence rate was 0% in Group 1 and 3.3% (1 eye) in Group 2 ( P = 1.00). Postoperatively, scleral whitening occurred in 6 (20%) eyes in Group 1 and none in Group 2 ( P = 0.015)., Conclusion: Both techniques, BSE alone or with conjunctival flap from the inferior bulbar conjunctiva 1 month after intrapterygial MMC, resulted in negligible (0%-3.3%) recurrence of pterygium. Conjunctival flap significantly reduced (0%) the postoperative complication of scleral whitening. This is the first report of efficacy of conjunctival flap in reducing scleral whitening after intrapterygial MMC., Competing Interests: There are no conflicts of interest., (Copyright: © 2019 Oman Ophthalmic Society.)

Purpose: Coping strategies employed by people with visual disability can influence their quality of life (QoL). We aimed to assess coping in patients with low vision or blindness., Methods: In this descriptive cross sectional study, 60 patients (25-65 years) with <6/18 best-corrected vision (BCVA) in the better eye and vision loss since ≥6 months were recruited after the institutional ethics clearance and written informed consent. Age, gender, presence of other chronic illness, BCVA, coping strategies (Proactive Coping Inventory, Hindi version), and vision-related quality of life (VRQoL; Hindi version of IND-VFQ33) were recorded. Range, mean (standard deviation) for continuous and proportion for categorical variables. Pearson correlation looked at how coping varied with age and with VRQoL. The analysis of variance (ANOVA) and t-test compared coping scores across categorical variables. Statistical significance was taken at P < 0.05., Results: Sixty patients fulfilled inclusion criteria. There were 33 (55%) women; 25 (41.7%) had low vision, 5 (8.3%) had economic blindness, and 30 (50.0%) had social blindness; 27 (45.0%) had a co-morbid chronic illness. Total coping score was 142 ± 26.43 (maximum 217). VRQoL score (maximum 100) was 41.9 ± 15.98 for general functioning; 32.1 ± 12.15 for psychosocial impact, and 41.1 ± 17.30 for visual symptoms. Proactive coping, reflective coping, strategic planning, and preventive coping scores correlated positively with VRQoL in general functioning and psychosocial impact., Conclusion: Positive coping strategies are associated with a better QoL. Ophthalmologists who evaluate visual disability should consider coping mechanisms that their patients employ and should refer them for counseling and training in more positive ways of coping., Competing Interests: None

An 11-year-old girl presented with an insidiously evolving, reddish-brown, small, hard, elevated lesion, occupying the midsection of her face, which had been present since early childhood. There were also a few small white spots over the trunk. There was no history of seizures or visual deficit, and no burning on exposure to sunlight. There were no known congenital defect noted at birth, and her parents were nonconsanguineous. There was no significant family history. There were numerous 2- to 4-mm reddish-brown papules located symmetrically on the nose, nasolabial folds, and cheeks (Figure 1A). In addition, there was an uneven 3-cm plaque in the lumbosacral region that resembled orange peel-a shagreen patch (Figure 1B). There were also two well-defined, 5- to 10-mm, hypomelanotic, ivory-white macule(s) with irregular margins (Figure 1C). The buccal mucosa and nails were unremarkable, and indirect ophthalmoscopic and slitlamp examination of the eye was normal. Laboratory studies were unremarkable. Ultrasonography of the abdomen was normal, as were abdominal and chest x-rays.

Purpose: The aim of this study was to investigate the differences in anterior segment ocular parameters in anisometropia >1 D., Methods: This study included 202 eyes of 101 subjects ranging from 10 to 40 years of age with anisometropia of 1 D or more. The subjects were divided into groups according to anisomyopia, anisoastigmatism, and anisohypermetropia. After providing informed consent, each patient underwent a detailed ophthalmological examination including cycloplegic refraction, best-corrected visual acuity, cover test, axial length (AL) measurement using A-scan ultrasound biometer, keratometry, anterior chamber depth, and central corneal thickness measurement. For each participant, the eye with greater refractive error was compared to the fellow eye via paired t -tests. Correlations between parameters were studied using the Pearson correlation coefficient., Results: The average age of subjects was 21.7 ± 9.3 years. Of 101 subjects, 31 had anisomyopia; 42 had anisohypermetropia; and 28 had anisoastigmatism. A predisposition toward greater myopia in right eyes was noted in anisomyopia (24 of 31 subjects, 77%). The inter-ocular acuity difference was significant in all three groups ( p < 0.01). As the degree of anisometropia increased, there was significant positive correlation in the difference in AL in myopes (r = 0.863, p < 0.01) and hypermetropes (r = 0.669, p < 0.01) and the difference in corneal curvature in anisoastigmatism (r = 0.564, p = 0.002) and hypermetropes (r = 0.376, p = 0.014). A significant positive correlation was also present between the anterior chamber depth difference and refractive difference in hypermetropes (r = 0.359, p = 0.020)., Conclusions: This study showed that anisomyopia is correlated only with anterior chamber differences. Anisohypermetropia is correlated with AL differences as well as corneal curvature difference and anterior chamber depth difference. The amount of anisoastigmatism correlates only with corneal curvature difference., Competing Interests: Conflict of Interest: No potential conflict of interest relevant to this article was reported.

Context: Rehabilitation of the visually disabled depends on how they adjust to loss; understanding contributing factors may help in effective rehabilitation., Aim: The aim of this study is to assess adjustment to acquired vision loss in adults., Settings and Design: This observational study, conducted in the Department of Ophthalmology at a tertiary-level teaching hospital, included thirty persons (25-65 years) with <6/60 in the better eye, and vision loss since ≥6-months., Materials and Methods: Age, gender, rural/urban residence, education, current occupation, binocular distance vision, adjustment (Acceptance and Self-Worth Adjustment Scale), depression (Center for Epidemiologic Studies-Depression Scale), social support (Duke Social Support and Stress Scale), and personality (10-item Personality Inventory scale) was recorded., Statistical Analysis: To determine their effect on adjustment, Student's t-test was used for categorical variables, Pearson's correlation for age, and Spearman's correlation for depression, personality trait and social support and stress., Results: Of 30 persons recruited, 24 were men (80%); 24 lived in urban areas (80%); 9 were employed (30%); and 14 (46.6%) had studied < Class 3. Adjustment was low (range: 33%-60%; mean: 43.6 ± 5.73). Reported support was low (median: 27.2; interquartile range [IQR]: 18.1-36.3); reported stress was low (median: 0.09; IQR: 0-18.1). Predominant personality traits (max score 14) were "Agreeableness" (average 12.0 ± 1.68) and "Conscientiousness" (average 11.3 ± 2.12). Emotional stability (average 9.2 ± 2.53) was less prominent. Depression score ranged from 17 to 50 (average 31.6 ± 6.01). The factors studied did not influence adjustment., Conclusions: Although adjustment did not vary with factors studied, all patients were depressed. Since perceived support and emotional stability was low, attention could be directed to support networks. Training patients in handling emotions, and training family members to respond to emotional needs of persons with visual disability, might contribute to reducing stress and depression.

Background: Colour vision of candidates is tested in many medical colleges in India at the time of admission to undergraduate courses; however, there are no guidelines, and therefore no counselling, on how students with congenital colour vision deficiency (CCVD) should negotiate the medical course, and how best they can practise safely after graduation. Problems in interpreting coloured signs may lead to misdiagnosis. This study aimed to explore difficulties during clinical work that requires colour discrimination, and to offer suggestions on safe practice based on the findings and a review of the literature., Methods: We did a cross-sectional study after obtaining institutional ethical clearance and written informed consent. Thirty volunteer medical students with CCVD (≥3 errors on Ishihara chart) were matched with 30 volunteers from their own batch who made no errors. All participants interpreted colour-dependent clinical and laboratory photographs., Results: Students with CCVD made more errors (range 5-26; mean [SD] 13.17 [5.873] out of 75 items in 35 colour-dependent photographs) than colour-normal students (range 2-13; mean [SD] 5.53 [3.037], p<0.001). The nature of the errors suggested that medical students with CCVD could have problems in learning histology, pathology, haematology, microbiology, dermatology, paediatrics, medicine, biochemistry and during ophthalmoscopy., Conclusions: Screening at the time of admission will make students aware of their CCVD status and, through conscious practice thereafter, they may understand their limitations. Faculty could guide and prepare such students for safe practice.

Context: Caregivers who assist persons with visual impairment often neglect their needs, resulting in burden and depression. Rehabilitation efforts, directed to the disabled, seldom target the caregiver., Aim: To assess burden and depression in persons caring for blind individuals., Settings and Design: This was a cross-sectional study carried out in the outpatient department of a tertiary-level teaching hospital in New Delhi., Materials and Methods: Institutional Ethical Board approval was obtained and written informed consent too was obtained from the participants involved in this study. Persons with best-corrected vision <20/200 in the better eye, and their primary caregivers, were recruited. We recorded demography, other illness/disability, household income, relationship with disabled person, and caregiver burden (Caregiver Burden Scale) and depression (Centre for Epidemiologic Studies Depression Scale)., Statistical Analysis: Statistical analysis was carried out using SPSS version 20 (Released 2011. Armonk, NY: IBM Corp.); range, average, and standard deviation were determined for age, burden, and depression. The association between burden and depression was determined using Pearson's correlation; the relationship between degree of disability and caregiver burden and depression was determined using unpaired t-test; using multiple linear regression, factors were found to be statistically significant; significance was taken at P < 0.05., Results: Twenty-seven (53.0%) men and 24 (47.0%) women had visual impairment. Most caregivers (n = 40; 81.6%) were first-degree relatives or a spouse; 32 (65%) had schooling <5 years; and 29 (59%) were unemployed. Depression ranged from 21 to 52 (average 43.2 ± 5.71); it correlated with degree of disability (P = 0.012), household income (r = -0.320; P = 0.025), and burden (r = 0.616; P < 0.001). Burden ranged from 30 to 73 (average 54.5 ± 6.73) and correlated with degree of disability (P = 0.006). On multiple linear regression, burden predicted depression (r = 0.557; P < 0.001)., Conclusions: Caregivers merit community support, financial benefit, interventions to diagnose and treat depression, and training in coping. Centers that provide disability certification could offer counseling.

Tuberous sclerosis complex (TSC) is a well-known clinical entity, characterized by facial angio-fibroma, shagreen patch, and hypo-melanotic, and confetti-like skin lesions. An exquisite fresh case is being narrated, emphasizing its microscopic pathology. The role of magnetic resonance imaging of the brain, in particular, is highlighted to define the large variety of neurological abrasions for determining its future progression.

Context: Visual disability is categorised using objective criteria. Subjective measures are not considered., Aim: To use subjective criteria along with objective ones to categorise visual disability., Settings and Design: Ophthalmology out-patient department; teaching hospital; observational study., Material and Methods: Consecutive persons aged >25 years, with vision <20/20 (in one or both eyes) due to chronic conditions, like cataract and refractive errors, were categorized into 11 groups of increasing disability; group-zero: normal range of vision, to group-X: no perception of light, bilaterally. Snellen's vision; binocular contrast sensitivity (Pelli-Robson chart); automated binocular visual field (Humphrey; Esterman test); and vision-related quality of life (Indian Visual Function Questionnaire-33; IND-VFQ33) were recorded., Statistical Analysis: SPSS version-17; Kruskal-wallis test was used to compare contrast sensitivity and visual fields across groups, and Mann-Whitney U test for pair-wise comparison (Bonferroni adjustment; P < 0.01). One-way ANOVA compared quality of life data across groups; for pairwise significance, Dunnett T3 test was applied., Results: In 226 patients, contrast sensitivity and visual fields were comparable for differing disability grades except when disability was severe (P < 0.001), or moderately severe (P < 0.01). Individual scales of IND-VFQ33 were also mostly comparable; however, global scores showed a distinct pattern, being different for some disability grades but comparable for groups III (78.51 ± 6.86) and IV (82.64 ± 5.80), and groups IV and V (77.23 ± 3.22); these were merged to generate group 345; similarly, global scores were comparable for adjacent groups V and VI (72.53 ± 6.77), VI and VII (74.46 ± 4.32), and VII and VIII (69.12 ± 5.97); these were merged to generate group 5678; thereafter, contrast sensitivity and global and individual IND-VFQ33 scores could differentiate between different grades of disability in the five new groups., Conclusions: Subjective criteria made it possible to objectively reclassify visual disability. Visual disability grades could be redefined to accommodate all from zero-100%.
