Pattern visual evoked potential and foveal sensitivity in amblyopia.

PURPOSE: Amblyopic eyes show impaired visual functions such as poor visual acuity and reduced foveal sensitivity. The purpose of this study was to determine the association between foveal threshold and visual evoked potentials (VEP) in strabismic and anisometropic amblyopia. METHODS: Forty-five subjects (age range: 7-28 years, 43.3% female) including 15 strabismic and 15 anisometropic amblyopes, and 15 age-similar control subjects participated in this study. Each subject had pattern visual evoked potentials and foveal threshold recorded in each eye using RetiScan (Roland Consult, Germany) and Humphrey Visual Field Analyzer II (HFA II; Carl Zeiss Meditec Inc., Dublin, CA), respectively. These outcomes were compared among the amblyopic eyes, their fellow eyes, and the control eyes. RESULTS: Compared to the amblyopic eyes (Mean ± SD: 33.4 ± 3.48 dB), the foveal threshold was higher in fellow eyes (37.0 ± 2.04 dB, p = 0.0002) and in control eyes (38.7 ± 0.96 dB, p < 0.0001). Strabismic amblyopes had a lower foveal threshold than anisometropic amblyopes (31.8 ± 3.86 vs. 35.0 ± 2.17 dB, p = 0.005). Relative to the P100 peak time in fellow eyes (1° checks:116.1 ± 9.00 ms; 0.25° checks:118.8 ± 5.67 ms), amblyopic eyes had delayed P100 peak times for both 1° (122.7 ± 11.4 ms, p < 0.0001) and 0.25° (130.4 ± 11.2 ms, p < 0.0001) check sizes. There were also significant differences in P100 peak time between amblyopic and control eyes (1°:122.7 ± 11.4 vs.112.4 ± 5.01 ms, p = 0.15; 0.25°:130.4 ± 11.2 vs.113.9 ± 5.71 ms, p < 0.0001) and between fellow and control eyes (0.25°:118.8 ± 5.67 vs.113.9 ± 5.71 ms, p = 0.009). Amblyopic eyes exhibited lower N75-P100 amplitudes than fellow eyes (1°:12.6 ± 7.96 vs.15.9 ± 8.82 µV, p = 0.01; 0.25°:10.6 ± 6.11 vs. 15.8 ± 10.6 µV, p = 0.001) and control eyes (0.25°: p = 0.0008). Foveal threshold correlated negatively with P100 peak time (1°: r = -0.45, p = 0.002 and 0.25°: r = -0.58, p < 0.0001) and positively with N75-P100 amplitude responses (1°: r = 0.42, p = 0.004 and 0.25°: r = 0.52, p = 0.002). CONCLUSIONS: Amblyopic eyes showed reduced pattern VEP amplitudes and delayed peak times with significant associations with the foveal sensitivity. However, the VEP measures overlapped extensively between amblyopic and control eyes with no apparent criterion value for optimal discrimination, suggesting that foveal sensitivity might be a better discriminator of amblyopia than pattern VEP.

Antibiotics Use among Geriatric Patients Admitted in the Department of Medicine in a Tertiary Care Centre: A Descriptive Cross-sectional Study.

Introduction: Ageing predisposes to increased risk of infections which make these population vulnerable to high risk of various chronic co-morbidities, organ dysfunction and mortality. Increased frequency of infections has led to an increasing proportion of geriatric patient admission to hospitals, and antibiotics therapy has long been recognized as a cornerstone in the treatment of infections. The aim of this study was to find out the prevalence of antibiotic use among geriatric patients admitted to the Department of Medicine in a tertiary care centre. Methods: A descriptive cross-sectional study was conducted among geriatric patients admitted to Department of Medicine in a tertiary care centre from 1 May 2022 to 31 August 2022. Ethical approval was obtained from the Institutional Review Committee (Reference number: 17/22). Patients with the age of ≥60 years, admitted to the Department of Medicine who stayed for at least 24 hours was included as the study population. Convenience sampling method was used. Point estimate and 95% Confidence Interval were calculated. Results: Among 520 geriatric patients, antibiotics was used in 252 (48.46%) (44.16-52.76, 95% Confidence Interval) patients. Ceftriaxone was the most common antibiotic used in 165 (65.48%) patients, followed by oral azithromycin in 72 (28.57%). The mean antibiotics used per patient was 1.59±0.73. Conclusions: The prevalence of antibiotic use in the geriatric population was found to be lower than in the other studies done in similar settings. Keywords: aged; antibiotics; drug utilization.

Anterior Distal Tibial Guided Growth for recurrent equinus deformity in idiopathic Congenital Talipes Equinovarus treated with the Ponseti method.

INTRODUCTION: Distal Anterior Tibial Guided Growth has been shown to be useful to correct recurrent equinus deformity after open surgical release for Congenital Talipes Equinovarus. This has not been evaluated in a recurrence after use of the Ponseti method, where soft tissue releases are currently understood as the mainstay of treatment. METHODS: Patients with recurrence of equinus component of CTEV, who underwent DATGG with at least 6-month follow-up were identified retrospectively. The criteria for performing this procedure were (1) equinus not correctable to neutral passively (2) the feeling of a bony block to dorsiflexion clinically as evidenced by a supple Achilles' tendon at maximum dorsiflexion and (3)a finding of a flat-top talus radiologically. Successful treatment was defined by the achievement of heel strike on observation of gait. Details of the index procedure including concurrent procedures, any complications and their treatment, past and subsequent treatment episodes were retrieved from electronic patient records. Pre-op and last available post-op X-rays were evaluated for change in the anterior distal tibial angle and for flat-top talus deformity. RESULTS: We identified 22 feet in 16 patients, with an average follow-up was 25 (8.8-47.3) months. The mean aDTA changed from 88.9 (82.3-94.5) to 77.0 (65.0-83.9) degrees, which was statistically significant (p < 0.0001) using the Paired t-test. Clinically, 17 feet (77 %) obtained a plantigrade foot with a normal heel strike. Complications were identified in 5 feet and include staple migration, oversized staple, superficial infection, iatrogenic varus deformity. Recurrence after completed treatment was noted in one foot. CONCLUSION: This procedure should form a part of the armamentarium of procedures for treating equinus component of CTEV recurrences even in feet not treated previously by open procedures. When used in patients without significant surgical scarring it helps to address bony and soft-tissue factors, leading to effective treatment. LEVEL OF EVIDENCE: Therapeutic Level IV.

Learning from health system actor and caregiver experiences in Ghana and Nepal to strengthen growth monitoring and promotion.

BACKGROUND: Globally, growth monitoring and promotion (GMP) of infants and young children is a fundamental component of routine preventive child health care; however, programs have experienced varying degrees of quality and success with enduring challenges. The objective of this study was to describe implementation of GMP (growth monitoring, growth promotion, data use, and implementation challenges) in two countries, Ghana and Nepal, to identify key actions to strengthen GMP programs. METHODS: We conducted semi-structured key informant interviews with national and sub-national government officials (n = 24), health workers and volunteers (n = 40), and caregivers (n = 34). We conducted direct structured observations at health facilities (n = 10) and outreach clinics (n = 10) to complement information from interviews. We coded and analyzed interview notes for themes related to GMP implementation. RESULTS: Health workers in Ghana (e.g., community health nurses) and Nepal (e.g., auxiliary nurse midwives) had the knowledge and skills to assess and analyze growth based on weight measurement. However, health workers in Ghana centered growth promotion on the growth trend (weight-for-age over time), whereas health workers in Nepal based growth promotion on measurement from one point in time to determine whether a child was underweight. Overlapping challenges included health worker time and workload. Both countries tracked growth-monitoring data systematically; however, there was variation in growth monitoring data use. CONCLUSION: This study shows that GMP programs may not always focus on the growth trend for early detection of growth faltering and preventive actions. Several factors contribute to this deviation from the intended goal of GMP. To overcome them, countries need to invest in both service delivery (e.g., decision-making algorithm) and demand generation efforts (e.g., integrate with responsive care and early learning).

Self-medication in Primary Dysmenorrhea among Undergraduate Students in a Medical College: A Descriptive Cross-sectional Study.

Introduction: Primary dysmenorrhea is painful menstruation in women with normal pelvic anatomy, usually beginning during adolescence, primarily associated with a normal ovulatory cycle. There is an increased likelihood of self-medication among medical students. The aim of this study is to find out the prevalence of self-medication in primary dysmenorrhea among undergraduate students in a medical college. Methods: A descriptive cross-sectional study was conducted in a medical college among undergraduate female students with primary dysmenorrhea from 1 February 2022 to 31 May 2022. Ethical approval was obtained from the Institutional Review Committee of the same institute (Reference number: 254/2021). Convenience sampling was done. Data were collected through a self-administered questionnaire. Point estimate and 95% Confidence Interval were calculated. Results: Among 213 students with primary dysmenorrhea, self-medication was found to be in 78 (36.62%) (30.15-43.09, 95% Confidence Interval)). Among all the self-medications used, mefenamic acid was most common, used by 45 (57.69%) students, followed by paracetamol 11 (14.10%). Conclusions: The prevalence of self-medication practice in primary dysmenorrhea among undergraduate students was lower when compared to similar studies done in similar settings. Keywords: dysmenorrhea; menstruation; prevalence; self medication.

Maternal Near Miss Analysis in Three Hospitals of Nepal: An Assessment Using Three Delays Model.

BACKGROUND: Maternal Near Miss cases have similarities with those dying from such complications and so present an important opportunity to improve practice. This study was conducted to assess the prevalence of Maternal Near Miss events and identify the delays experienced. METHODS: This was a facility-based cross-sectional study conducted in three tertiary referral hospitals from three provinces of Nepal. All the women surviving a near miss event during six months data collection period were included in the study. RESULTS: There were 67 near miss cases, 7 maternal deaths, and 9158 live births in the study hospitals during the data collection period. This resulted in Maternal Near Miss ratio of 7.31/1000 live births and facility-based Maternal Mortality Ratio of 76/100,000 live births. Severe obstetric haemorrhage (54%) was the most frequent clinical cause of near miss, followed by hypertensive disorders (43%). At least one type of delay was experienced by 85% women. First delay occurred in 63% (42 of 67) cases, second delay occurred in 52% (33 of 62) cases and third delay occurred in 55% (37 of 67) cases. CONCLUSIONS: This study found out that all three delays were common among women experiencing maternal near miss event. Raising awareness regarding dangers signs, improving referral system and strengthening ability of health workers can help in reducing these delays.

Study of Self-medication among First and Seventh Semester Medical and Dental Undergraduate Students of Tertiary Care Teaching Hospital in Nepal: A Descriptive Cross-sectional Study.

INTRODUCTION: Although appropriate self-medication can ease minor illness and is time and costeffective, it can lead to irrational drug use and increased resistance, leading to prolonged morbidity. Inclined towards medical information and drug indices, medical students have an open arena for self-medication practice. This study was conducted to find the prevalence of self-medication among first and seventh semester medical and dental students in a tertiary care hospital. METHODS: A descriptive cross-sectional study was conducted among medical and dental undergraduates from July 2020 to August 2020 after receiving ethical clearance from the Institutional Review Committee of Kathmandu University School of Medical Sciences (IRC Approval Number:35/20). A questionnaire was responded to by participants through a google form. Participants were enrolled through the convenience sampling method. Data were collected and entered in Microsoft Excel and analyzed using Statistical Package for Social Sciences version 25. RESULTS: Out of 199 respondents, the prevalence of self-medication was 100 (50.3%) (46.76-53.84 at 95% Confidence Interval). First semester medical 36 (73.5%) and dental undergraduates 24 (80%) had higher practice. Seventh-semester medical students 14 (51.9%) usually self-medicated within one day of onset of symptoms. Headache 47 (47%) was the most common indication. Analgesics 62 (62%) were most commonly used drugs procured most commonly from pharmacies 114 (57.3%). Dosage form was drug selection criteria for 120 (60.3%) students. CONCLUSIONS: Since self-medication is crammed with serious health hazards, proper exposure to the topic should be given to medical, dental students, and pharmacists. The implication of selfmedication into the pharmacology syllabus is a must.

Drug Prescription in the Department of Medicine of a Tertiary Care Hospital according to the World Health Organization/International Network for Rational Use of Drugs Core Indicators: A Descriptive Cross-sectional Survey.

INTRODUCTION: To establish appropriate health care services in developing countries, rationalization of drug use holds utmost importance. Drug use patterns can be found out using Core Indicators of the World Health Organisation in collaboration with the International Network of Rational Use of Drugs. With the help of the indicators, this study aimed to find out the way the drugs were prescribed in the Medicine out-patient department of a tertiary care hospital. METHODS: A descriptive cross-sectional survey was conducted from October 2019 to March 2020 in a tertiary care hospital. The ethical approval was taken from the Institutional Review Committee of the Dhulikhel hospital (reference number 198/19). Convenient sampling was done. After taking consent from the patient, data was collected from prescriptions written on the patient's card. The data were analysed using Statistical Package for the Social Sciences Version 25. Descriptive statistics were applied and the results were expressed as frequency and percentage, mean and standard deviation. RESULTS: A total of 559 prescriptions were analysed, of which a total of 1427 medicines were found to be prescribed with an average number of medicines per the prescription of 2.55±1.388. Drugs prescribed by generic name were 820 (57.5%), antibiotics were 138 (9.7%) and injections were 8 (0.6%). Drugs prescribed from the Essential Drug List of Nepal was 939 (65.8%). CONCLUSIONS: Our study revealed that despite some results being up to the mark, there is a requisite for the proper regulation of prescribing and dispensing drugs in order to promote rationalisation.

Attitude and self-care practice on hypertension among antihypertensive medication users in a tertiary care hospital Nepal.

BACKGROUND: Hypertension a "silent killer" is a serious global health problem, whose prevalence is increasing in Nepal. OBJECTIVE: This study aimed to determine the attitude and practice of hypertension among anti-hypertensive medication users in a tertiary care teaching hospital in western Nepal. METHODOLOGY: A hospital-based cross-sectional study design was used among 136 hypertensive patients under medication, aged ⩾ 30 years, and visiting medical outpatient department, medical ward, and geriatric ward, using a non-probability convenience sampling technique. Semi-structured questionnaires were used for data collection through interviews. Descriptive and inferential statistics were used, and a p value < 0.05 was considered statistically significant. RESULTS: Most of the patients were male (56.6%), mean ± standard deviation age was 56.74 ± 12.58. Majority of them were Hindu (69.9%), upper caste people (29.4%), illiterate (22.1%), and house maker (27.2%). Half of the patients (50.7%) had a positive attitude and more than half (52.2%) had performed adequate self-care practice. Selected variables such as educational status and dietary pattern and attitude were significantly associated, whereas no association was found between sociodemographic variables and self-care practice. Attitude and self-care practices were found strongly associated with one another (p = 0.002). CONCLUSION: Our study found that half of the study population had positive attitude, and more than half of them had performed adequate self-care practice. Hence, educational interventions and awareness programs on dietary aspects should be focused for improving the attitude and practice of all the patient groups.

Factors affecting final functional outcomes in open-globe injuries and use of ocular trauma score as a predictive tool in Nepalese population.

BACKGROUND: Open globe injury (OGI) is one of the most devastating form of ocular trauma. The aim of the study is to identify the epidemiology and predict visual outcomes in traumatic open globe injuries using ocular trauma score (OTS) and correlate with final visual acuity (VA) at 3 months. METHODS: Patients older than 5 years, presenting to B.P. Koirala Lions Centre for Ophthalmic Studies (BPKLCOS) from March 2016- March 2017 with OGI that met inclusion criteria were evaluated. Patient profile, nature and cause of injury, and time to presentation were recorded. Patients were managed accordingly and followed up to 3 months. An OTS score for each patient was calculated and raw scores were categorized accordingly. The VA after 3 months were compared to the predicted OTS values. RESULTS: Seventy-three eyes of 72 patients were examined. 76 % were male, and the mean age was 26.17 years (median, 23.5 years). The mean time from injury to presentation was < 6 hours (30 patients, 41 %). Thirty-seven eyes (51 %) had zone I trauma, followed by twenty eyes (27 %) with zone II, and sixteen eyes (22 %) with zone III trauma. Sixty-five patients (90 %) were managed surgically, and fifty (68 %) received intravitreal antibiotics with steroid. When compared, the projected VA as per OTS were able to predict actual final visual outcomes in 60 % of the eyes with OGI of various zones. CONCLUSIONS: OTS can be an accurate predictive tool for final visual acuity even with a short follow up period of 3 months; with poor presenting visual acuity, delayed presentation, posterior zones of injury, need for intravitreal injections, endophthalmitis, and globe rupture associated with poorer prognosis.

Role of choroidal thickness assessment in unilateral acute anterior uveitis.

Purpose: The aim of our study was to investigate the change in the subfoveal choroidal thickness in unilateral acute anterior uveitis with treatment. Choroidal inflammation is uncommon but can occur in the acute stage of anterior uveitis. Methods: All diagnosed patients with the first episode of unilateral acute anterior uveitis were included in the study conducted for a period of July 2017-July 2018. Choroidal thickness at subfoveal region was measured with spectralis spectral domain optical coherence tomography using enhanced depth-imaging scans. Standardized, masked manual measurement of the choroidal thickness was performed in the center of the ETDRS fields. The unaffected fellow eye of the same patient was taken as a control group and their subfoveal choroidal thickness was measured. Follow up of the patients was done at 2 weeks posttreatment to reevaluate the choroidal thickness. Results: A total of 61 eyes of 61 patients with unilateral acute anterior uveitis were included in the study. The mean central subfoveal choroidal thickness was significantly higher (304.82 ± 73.17 µm) as compared to that of controls (251.28 ± 66.38 µm) at presentation (P < 0.001). Following treatment and at two weeks follow up, the subfoveal choroidal thickness significantly reduced from 304.82 ± 73.17 to 274.46 ± 63.82 µm (P < 0.001). Also the subfoveal choroidal thickness was positively correlated with visual acuity (r = 0.22, P < 0.251) before treatment. Conclusion: Acute anterior uveitis is associated with an increase in the subfoveal choroidal thickness followed by the significant decrease in choroidal thickness with treatment, suggesting that choroid is also inflamed along with anterior segment inflammation.

Perinatal Risk Factors for Retinopathy of Prematurity in Preterm and Low Birth Weight Neonates.

BACKGROUND: Retinopathy of prematurity (ROP) is emerging as a leading cause of childhood blindness. The incidence of ROP is likely to increase after improvement in neonatal care unit in premature neonates. This study is conducted to determine the perinatal risk factors for ROP in preterm and low birth weight neonates. METHODS: This is a prospective, descriptive and clinical; hospital based study. A total of 92 preterm neonates with gestational age of 36 weeks or less and birth weight of 2000 grams or less admitted in Neonatal Intensive Care Unit (NICU) were screened. Detailed antenatal, perinatal and neonatal history; birth asphyxia and subsequent oxygen support records were noted. All the neonates underwent detailed anterior and posterior segment eye examination with indirect binocular ophthalmoscope after pupil dilatation within 4 weeks of life. Retinal vascular changes were classified according to the International Classification of Retinopathy of Prematurity. The Chi-square test with odds ratio was performed to derive the association between ROP and antenatal, perinatal and neonatal factors. A p-value was considered significant at 0.05. RESULT: Out of 92 neonates, 21(22.8%) developed ROP. Twelve neonates (13%) had stage-1 ROP, 6(6.5%) had stage-2 and 3(3.3%) had stage-3 ROP. Birth weight (OR=2.9; p=0.04; 95% CI=1.0-8.3), gestational age (OR=3.9; p=0.01; 95% CI=1.3-11.8) and time span of oxygen exposure (OR=2.9; p=0.05; 95% CI=1.0-8.4) had a strong association with ROP. CONCLUSION: The incidence of ROP is significantly high among preterm low birth weight neonates. The risk of developing ROP becomes even greater with lower gestational age and more duration of oxygen exposure.

Flash VEP in clinically stable pre-term and full-term infants.

PURPOSE: Pre-term infants are at risk of abnormal visual development that can range from subtle to severe. The aim of this study was to compare flash VEPs in clinically stable pre-term and full-term infants at 6 months of age. METHODS: Twenty-five pre-term and 25 full-term infants underwent flash VEP testing at the age of 6 months. Monocular VEPs were recorded using flash goggles on a RETIscan system under normal sleeping conditions. Amplitude and peak time responses of the P2 component in the two eyes were averaged and compared between the two groups. Multiple regression analyses were performed to assess the relationship of the P2 responses with birth weight (BW) and gestational age (GA). RESULTS: At 6 months corrected age, pre-term infants had significantly delayed P2 peak times than full-term infants (mean difference: 10.88 [95% CI 4.00-17.76] ms, p = 0.005). Pre-term infants also showed significantly reduced P2 amplitudes as compared to full-term infants (mean difference: 2.36 [0.83-3.89] µV, p = 0.003). Although the regression model with GA and BW as fixed factors explained 20% of the variance in the P2 peak time (F2,47 = 5.98, p = .0045), only GA showed a significant negative relationship (ß = -2.66, p = .003). Neither GA (ß = 0.21, p = .28) nor BW (ß = 0.001, p = .32) showed any relationship with P2 amplitude. CONCLUSIONS: Our results demonstrate that, compared with full-term infants, clinically stable pre-term infants exhibit abnormal flash VEPs, with a delay in P2 peak time and a reduction in P2 amplitude. These findings support a potential dysfunction of the visual pathway in clinically stable pre-term infants as compared to full-term infants.

Prevalence of Psychoactive Drug Use among Medical Students in a Medical College of Nepal.

INTRODUCTION: Psychoactive drug is a worrisome and emerging global problem. This is a disturbing matter, especially in the case of medical students, as it affects not only their health and academic performance alone but their clinical efficiency as well. This study aims to determine the prevalence of psychoactive drug use among medical students in a medical college in Nepal. METHODS: A descriptive cross-sectional study was conducted after receiving ethical clearance from the Institutional Review Committee (Ref: 258/19) among undergraduate medical students from December 2019 to June 2020. Convenience sampling was used to collect data. Data analysis was done in the Statistical Package for Social Sciences. Point estimate at 95% confidence interval was calculated along with frequency and proportion for binary data. RESULTS: The prevalence of psychoactive drug abuse was found to be 76 (44.2%) [CI= 43.6%â€"44.8%]. The study showed males 59 (59%) were more indulged in abuse than females 17 (23.6%). Alcohol 72 (41.86%) was the most commonly used, then was tobacco 24 (13.95%) followed by cannabis 17(9.88%). Only two students were sedative and opioid abusers. Pleasure 38 (31.70%) and experimentation 29 (24.20%) were the two major causes of substance abuse. Tobacco was used more frequently 14 (58.33%) used daily and found to have more financial and health-related issues in the last three months. CONCLUSIONS: Even almost half of the students were using some form of psychoactive drugs, the majority of them were occasional users. Proper counseling needs to be done to address this problem. Further study should be conducted to address the influencing factors and adverse outcomes.

Awareness of Eye Health and Diseases among the Population of the Hilly Region of Nepal.

PURPOSE: To collect information regarding awareness and knowledge of eye health and diseases among the population of the hilly region of Nepal. METHODS: In a population-based survey, 1834 participants were enrolled in to the study. Field procedures included the development of a survey questionnaire, field orientation, pretesting, and household data collection. Association between knowledge of eye diseases was derived using the Chi-square test and odds ratios with a 95% confidence interval. A P value of ≤0.05 was considered significant. RESULTS: Most participants were 31-40 years old (33.4%), female (51.1%), of upper caste (43.4%), Hindus (83.3%), received secondary level of education (34.4%), and involved in agriculture (48.6%). Awareness of cataract, night blindness, glaucoma, strabismus, and systemic diseases was 74.6%, 53.4%, 17.4%, 70.8%, and 46.5%, respectively. Knowledge regarding these diseases among those aware was 39.1%, 72.2%, 50.9%, and 92.3%, respectively. Awareness of cataract was significantly higher (88.4%) among higher caste groups (P < 0.001; OR, 4.29; 95% CI, 3.34-5.54), followed by business as an occupation (88.2%; P = 0.001; OR, 2.65; 95% CI, 1.44-4.9). Awareness of night blindness was significantly higher among students (72.6%; P < 0.001; OR, 2.46; 95% CI, 1.65-3.67). CONCLUSION: There was a general lack of awareness and knowledge of common eye diseases. Improved awareness and knowledge are required for the prevention, early treatment, and access to eye care.

Orbital Teratoma: A rare congenital tumour.

BACKGROUND: Orbital teratomas are congenital, unilateral germ cell tumors, which are present at birth with moderate to massive proptosis. The rare tumour has to be managed individually and is at times difficult. CASE: A female child in her 2nd day of life was brought to our department with complains of forward bulging of the left eye which was noticed since the time of her birth. OBSERVATION: Examination and investigations revealed a mass with scattered foci of calcification. The mass was causing expansion of left orbit with thinning and scalloping of bony boundaries of left orbit with no intracranial component. The scan suggests the diagnosis of orbital teratoma which was further confirmed by histopathological examination. CONCLUSION: The rare tumour presents a challenge in management. The aim of management depends upon the extent of tumour, preservation of vision whenever possible, promotion of normal orbital growth and cosmesis.

Refractive Status in Nepalese Pre-Term and Full-Term Infants Early in Life.

SIGNIFICANCE: This study suggests that pre-term infants, even without retinopathy of prematurity, are at risk for abnormal refractive development and informs the need for close monitoring of refractive error in such infants, regardless of their retinopathy of prematurity status. PURPOSE: The present study aims to investigate the refractive error trend in Nepalese pre-term infants without retinopathy of prematurity (ROP) in the first 6 months of life and explore the association of refractive error with birth weight (BW) and gestational age (GA). METHODS: Thirty-six pre-term infants without ROP and 40 full-term infants underwent cycloplegic retinoscopy at birth, term (for pre-term only), 3 months, and 6 months chronologically. Refractive status was classified into emmetropia (mean spherical equivalent refraction [SER] 0 to +3.00D), myopia (SER < 0.00D), and significant hyperopia (SER > +3.00D). Refractive parameters at various age points were compared between the pre-term and full-term infants using general linear model repeated measures ANOVA. RESULTS: At birth, the SER in the pre-term infants was +0.84 ± 1.72D; however, there was a shift toward myopia at 6 months of age (SER = -0.33 ± 1.95D). There was a significant difference in SER, astigmatism, and anisometropia between pre-term and full-term infants by 6 months of age (P < .01). Astigmatism and anisometropia showed an increasing trend with age in pre-term infants (P < .05 at 6 months) in contrast to a decreasing trend in full-term infants (P < 0.05 at 3 and 6 months). In pre-term infants, there was a statistically significant positive relationship between GA and SER (ß = 0.32, R = 17.6%, P < .05) but a negative relationship between BW and astigmatism (ß = -1.25, R = 20.6%, P < .01). CONCLUSIONS: Pre-term infants who do not develop ROP show a trend toward increasing myopia and demonstrate greater astigmatism and anisometropia than full-term infants in their first 6 months of life.

Macular thickness and macular volume measurements using spectral domain optical coherence tomography in normal Nepalese eyes.

PURPOSE: To record the normative values for macular thickness and macular volume in normal Nepalese eyes. METHODS: In all, 126 eyes of 63 emmetropic subjects (mean age: 21.17±6.76 years; range: 10-37 years) were assessed for macular thickness and macular volume, using spectral domain-optical coherence tomography over 6×6 mm(2) in the posterior pole. A fast macular thickness protocol was employed. Statistics such as the mean, median, standard deviation, percentiles, and range were used, while a P-value was set at 0.05 to test significance. RESULTS: Average macular thickness and total macular volume were larger in males compared to females. With each year of increasing age, these variables decreased by 0.556 µm and 0.0156 mm(3) for average macular thickness and total macular volume, respectively. The macular thickness was greatest in the inner superior section and lowest at the center of the fovea. The volume was greatest in the outer nasal section and thinnest in the fovea. The central subfield thickness (r=-0.243, P=0.055) and foveal volume (r=0.216, P=0.09) did not correlate with age. CONCLUSION: Males and females differ significantly with regard to macular thickness and macular volume measurements. Reports by other studies that the increase in axial length reduced thickness and volume, were negated by this study which found a positive correlation among axial length, thickness, and volume.

Burden of ocular and visual disorders among pupils in special schools in Nepal.

OBJECTIVES: To determine detailed oculo-visual characteristics of children with intellectual disability studying in special schools and explore the burden of visual impairment. DESIGN OF THE STUDY: Detailed ophthalmic examination was carried out in all pupils studying at the seven special needs schools of Kathmandu valley, Nepal. Ophthalmic examination included case history, presenting distance visual acuity, cycloplegic refraction, binocular vision examination, contrast sensitivity and anterior and posterior segment evaluation. MAIN OUTCOME MEASURES: Ocular and visual status of children. RESULTS: Refractive errors (40%) and strabismus (17%) were the commonest visual disorders in our study children. Ninety-five per cent of the children who had clinically significant refractive errors presented without any correction. Visual impairment was present in 25% of the children. Severe visual impairment or worse was present in 3% of the children. Other common ocular findings were conjunctivitis, blepharitis, chalazion and ectropion. CONCLUSIONS: High prevalence of preventable visual impairment in this population requires immediate attention. It is hoped that the formulation of proper vision care guidelines at a national level may help in early detection and management of visual disorders in this special population and enhance their quality of life.
