RESUMO

Background: The use of human amniotic membrane transplantation is rapidly increasing for the management of various ocular surface disorders. Despite its numerous advantages, amniotic membrane is not widely available due to the lack of awareness among ophthalmologists regarding its preparation and preservation techniques. Purpose: To provide an instructional video demonstrating the technique of harvesting, preparation, preservation of human amniotic membrane, and its uses in the management of ocular surface diseases. Synopsis: The amniotic membrane is the innermost layer of the human placenta. Properties of the amniotic membrane, like the presence of various growth factors, anti-inflammatory and anti-angiogenic factors, and its low immunogenicity, contribute to its ability to promote epithelial growth and differentiation with the reduction in fibrosis during healing. To harvest amniotic membrane, informed consent is obtained from a patient undergoing an elective caesarian section, and the donor is screened to exclude the risk of infections. Under sterile precautions, the amniotic membrane is separated from the chorion and washed free of blood clots. With the epithelial surface up, the amniotic membrane is spread uniformly without folds or tears on individually sterilized 0.22 µm nitrocellulose filter papers of the required sizes. The prepared filter paper with the adherent amniotic membrane is placed in freshly prepared Dulbecco's Modified Eagle's Medium and stored at -80°C. The amniotic membrane can be used for surgical procedures like symblepharon release, pterygium or dermoid excision, perforated ulcers, nonhealing epithelial defects, etc. Highlights: Instructional videos demonstrating the preparation and preservation of amniotic membrane are very sparse. This video clearly explains how any ophthalmologist can learn to prepare and preserve the human amniotic membrane and gives a glimpse of its properties, advantages, and scope of use.

RESUMO

PURPOSE: The purpose of this study was to assess the retinal nerve fiber layer (RNFL) thickness in patients with pseudoexfoliation (PXF) and to correlate it with anterior segment parameters such as intraocular pressure (IOP), central corneal thickness (CCT), pigments in angle structures, and grades of PXF. METHODOLOGY: This was a cross-sectional comparative study in a tertiary care center. Patients having unilateral PXF were categorized as group 1. Age- and sex-matched healthy controls were categorized as group 2. All subjects underwent IOP measurement, CCT measurement, and retinal nerve fiber thickness measurement. Subjects in group 1 also underwent gonioscopy and perimetry. Data were entered and analyzed using the IBM-SPSS program (version 20.0); Chicago, IL. RESULTS: Mean RNFL thickness in group 1 was 85.91 ± 22.237 µ and in group 2 was 106.65 ± 6.1 µ. The mean RNFL thickness in patients with PXF syndrome was 103.38 ± 5.815 µ and in patients with PXF glaucoma was 67.82 ± 17.984 µ. The mean CCT in patients with PXF syndrome was 516.41 ± 23.03 µ and in patients with PXF glaucoma was 507 ± 33.05 µ and control group was 526.6 m. The mean IOP in patients with PXF syndrome was 8 ± 6.01 mmHg; in patients with PXF glaucoma was 17.21 ± 7.33 mmHg; and in the control group was 14.12 ± 2.693 mmHg. There was a negative correlation between IOP and RNFL thickness, and a positive correlation between CCT and RNFL thickness, but it was not statistically significant. A statistically significant correlation was found between grades of PXF and RNFL thinning with a correlation coefficient of 0.437 (P = 0.001). CONCLUSION: Patients with PXF have a lower CCT, higher mean IOP, and RNFL thinning compared to normal subjects. The presence of grade 3 PXF (on the lens surface edge) showed a statistically significant correlation with RNFL thinning.

RESUMO

A 28-year-old male presented with a large conjunctival lobulated, nonpulsatile, red vascular lesion involving a large part of the temporal quadrant of the left globe. There was no proptosis or globe displacement, but the left eye abduction was limited. T2-weighted magnetic resonance imaging scan of the brain and orbit revealed an extensive contrast-enhancing lobulated lesion in the left half of the face involving the upper lip, cheek, oral cavity, extraconal space of left orbit, and nasal cavity. He underwent surgical excision of the conjunctival lesion with amniotic membrane reconstruction.

RESUMO

Purpose: To study the effect of increasing grades of hypertensive retinopathy (HTR) on neonatal outcomes among preeclamptic women and assess the various maternal risk factors for HTR. Methods: A prospective cohort study was conducted on 258 preeclamptic women. The systolic and diastolic blood pressure (SBP and DBP), liver, and renal function parameters were collected besides basic demographic details. Dilated fundus examination with the Keith-Wagner-Barker classification was used to grade HTR. Following delivery, neonatal outcomes were evaluated. Results: Of the 258 preeclamptic women recruited, 53.1% had preeclampsia (PE), and 46.9% had severe preeclampsia. With increasing grades of HTR, a significant association with low birth weight (LBW) (p = 0.012) and preterm gestational age (p = 0.002) was noted but not with the Appearance, Pulse, Grimace, Activity and Respiration (APGAR) score (p = 0.062). Also, it did not increase the risk of retinopathy of prematurity (ROP), with most babies, even those born to mothers with high grades of HTR, showing no evidence of ROP (p = 0.025). Among the maternal factors, increasing age (p = 0.016), SBP (p < 0.001), DBP (p < 0.001), serum creatinine (p = 0.035), alanine aminotransferase (p = 0.008), lower hemoglobin (Hb) (p = 0.009), lower platelet (p < 0.001), and severe PE (p < 0.001) have been found to significantly affect the grade of HTR. Conclusion: Higher grades of HTR in the preeclamptic mother are associated with preterm delivery and LBW of the neonates but neither affect the APGAR score nor pose the risk of developing ROP.

RESUMO

PURPOSE: To assess the perinatal risk factors, clinical characteristics, and microbial profile in congenital nasolacrimal duct obstruction (CNLDO). METHODS: A prospective observational study was conducted in pediatric patients of age <5 years. After a thorough clinical evaluation, the diagnosis of the CNLDO was confirmed by a Jones dye test or fluorescein dye disappearance test. A microbiological culture of lacrimal sac resurge was done with a sterile swab stick without touching the lid margins. Antibiotic susceptibility was then performed for the standard antibiotics. RESULTS: Seventy-one eyes of 52 children were included in the study. The mean age was 3.4 months. Our research found an equal number of cases born via spontaneous vaginal delivery and Caesarean section. Nine children (17.3%) had associated systemic and ocular anomalies. The number of cultures that were positive for any growth was 19 (27%). The most common isolate was Streptococcus pneumoniae which constituted eight cases (42%), followed by Pseudomonas aeruginosa (15.8%), and Escherichia coli (10.5%). Other organisms that grew were Klebsiella pneumoniae, Staphylococcus aureus, Staphylococcus epidermidis and nonfermenting gram-negative bacilli. Gram-positive organisms were susceptible to ciprofloxacin, amoxiclav, and oxacillin, and most of them were resistant to erythromycin. In comparison, gram-negative organisms showed 62.5% resistance and 37.5% susceptibility to ciprofloxacin. CONCLUSIONS: CNLDO was more commonly unilateral, in male, preterm, and normal birth weight infants. Bilateral CNLDO was more commonly associated with coexisting ocular or systemic anomalies. Prematurity, delivery by Caesarean section, and presence of congenital anomalies were associated with a prolonged course. S. pneumoniae was the predominant isolate in our patient population.

RESUMO

PURPOSE: To assess the level of stereopsis in school children with spectacle-corrected refractive errors using Titmus fly and Randot stereo tests, evaluate the factors associated with the level of stereopsis, and determine the level of agreement between the two tests. METHODS: A cross-sectional study was done on 5- to 18-year-old school-children wearing spectacles for at least 1-month duration. Visual acuity was assessed using Snellen's visual acuity chart, and their spectacle correction being used currently was measured using an auto lensmeter. The level of stereopsis was assessed using Randot and Titmus fly stereo tests. Data were entered using Microsoft Excel and analyzed using IBM-SPSS version 20, Chicago, IL. The associations between stereopsis and type of refractive error, visual acuity, age, and gender were analyzed. An agreement between Randot and Titmus fly test was done using Kappa statistics. RESULTS: A total of 222 children (101 boys and 121 girls; mean age 13 years) were assessed. Astigmatism was the most prevalent refractive error (60.4%), followed by myopia (24.8%) and hypermetropia (1.4%). Thirty children (13.5%) had anisometropia. All hyperopes had normal stereopsis. Children with spherical myopia had better stereopsis, followed by astigmatism and anisometropia in the same order (P = 0.036). Children with anisometropia ≤1.5 D had better stereopsis than anisometropia more than 1.5 D. Stereopsis was also found to have no correlation with the age and visual acuity at the time of testing or the age at which the child first started wearing spectacles. Stereopsis values obtained from Randot and Titmus fly stereo tests showed moderate agreement with Kappa value 0.581. CONCLUSION: Anisometropia and astigmatism are the most critical factors determining the level of stereopsis in refractive errors.

RESUMO

PURPOSE: To assess the refractive outcomes in eyes with severe Retinopathy of prematurity (ROP) after treatment with the frequency-doubled neodymium-doped yttrium aluminum garnet (Nd-YAG) laser 532 nm (green laser) at 1-2 years of age and compare with eyes that underwent spontaneous regression of ROP and to identify the risk factors associated with the refractive outcomes in laser-treated eyes with severe ROP. METHODOLOGY: Infants who underwent laser treatment with green laser were enrolled in Group 1 and those who had spontaneous regression of ROP were enrolled in Group 2. All these children underwent a visual assessment, refraction using 1% cyclopentolate eye drops and indirect ophthalmoscopy at 1-2 years of age. Data regarding the gestational age, sex, birth weight, inborn (born in our institution) or outborn (born outside and referred to us), stage and zone of ROP and laser spots given were obtained from the treatment records. Data were analyzed using SSPS 19.0 software for Windows (SSPS Inc., Chicago, Illinois, USA). RESULTS: A total of 102 infants were enrolled, 51 in each group. Visual acuity ranged from 0.25-1 cycles per cm in both groups. Spherical equivalent (SE) ranged from - 8.25 D to + 5.50 D in Group 1 and -1.00D to +4.00D in Group 2. Group 1 had an incidence of 23.5% Myopia and 33.4% Astigmatism which was significantly more than Group 2. The linear regression model predicted a decrease in the SE by 0.658D if the number of laser spots increased by 1000 (P < 0.001). No other risk factors (gestational age/birth weight) were found to have a significant association with refractive errors in the lasered ROP group. CONCLUSIONS: Eyes with laser-treated severe ROP are frequently associated with myopia and astigmatism when compared to spontaneously regressed ROP. The number of laser spots delivered has a direct association with the amount of refractive error.

RESUMO

PURPOSE: The purpose is to study the ocular surface changes among patients with diabetes mellitus (DM) and to correlate them with tear film markers such as insulin-like growth factor (IGF)-1, interleukin (IL)-1ß, and tumor necrosis factor (TNF)-α levels. MATERIALS AND METHODS: The study was carried out on diabetic patients (>5 years' duration) and healthy age- and gender-matched controls with 21 individuals in each group. Schirmer's test for basal and reflex tear secretion, tear film breakup time (TBUT) for tear stability, ocular staining score (OSS) for dryness severity, ocular surface disease index (OSDI) for symptomatic assessment of dryness and conjunctival impression cytology (IC) for epithelial cell integrity, keratinization, squamous metaplasia, and goblet cell density was studied. Thirty microliters of tears were collected to test IGF-1, IL-1ß, and TNF-α levels. RESULTS: Patients with DM showed significantly low Schirmer's, TBUT, and OSS values than controls. OSDI score showed moderate-severe dryness in patients with DM and only mild symptoms among controls. An abnormal IC score was seen among cases and controls. The level of TNF-α was significantly increased in patients with DM and positively correlated with Schirmer and TBUT values (P < 0.05). CONCLUSION: Dry eye is more prevalent in patients with DM compared to controls as evidenced by poor OSDI score, Schirmer, TBUT, and OSS. TNF-α in the tears of patients with DM is a useful marker that showed a good correlation with Schirmer, TBUT, and dry eye symptoms. IC could not conclusively differentiate the dry eye status in patients with DM from controls.

RESUMO

Prevention and early management of postburn cicatricial ectropion is the best strategy to avoid ocular complications, with poor visual prognosis in extreme cases. A 51-year-old man presented with diminution of vision and absolute inability to close both eyes, 3 months after thermal burn injuries to face, upper limbs, and trunk. His best corrected visual acuity (BCVA) was 1/60 in BE. He had bilateral extremely severe ectropion involving both upper and lower lids with complete inability to close the eyes. The ensuing exposure keratitis developed secondary infection by Methicillin-resistant Staphylococcus aureus (MRSA) in the right eye and multidrug-resistant Pseudomonas aeruginosa in the left eye. His extreme ectropion prevented infection healing, so its release and full-thickness skin grafting was done when partial resolution of infection was noted. After 3 months, he had moderate residual ectropion in BE; vascularized corneal scar in the inferior part of the right eye (BCVA:20/40) and adherent leucoma in left eye (BCVA:HM). Prioritizing ectropion surgery in our extreme case for infection control, facilitated corneal healing. Our case highlights the extreme consequences of not taking preventive measures or of managing incident ectropion following thermal injury to the face.
