RESUMEN

PURPOSE: To evaluate the feasibility and outcome of a real-time retinopathy of prematurity (ROP) telescreening strategy using videoconferencing in a community setting in India. METHOD: In a prospective study, trained allied ophthalmic personnel obtained the fundus images in the presence of the parents and local childcare providers. Analysis of images and parental counseling were done in real time by an ROP specialist located at a tertiary center using videoconferencing software. A subset of babies was also examined using bedside indirect ophthalmoscopy by an ROP care-trained ophthalmologist. The data were analyzed using descriptive statistics, sensitivity, specificity, positive and negative predictive values, and correlation coefficient. RESULTS: Over 9 months, we examined 576 babies (1152 eyes) in six rural districts of India. The parents accepted the model as they recognized that a remotely located specialist was evaluating all images in real time. The strategy saved the travel time for ROP specialists by 477 h (47.7 working days) and for parents (47,406 h or 1975.25 days), along with the associated travel cost. In a subgroup analysis (100 babies, 200 eyes), the technology had a high sensitivity (97.2%) and negative predictivity value (92.7%). It showed substantial agreement (k = 0.708) with the bedside indirect ophthalmoscopy by ROP specialists with respect to the detection of treatment warranting ROP. Also, the strategy helped train the participants. CONCLUSION: Real-time ROP telescreening using videoconferencing is sensitive enough to detect treatment warranting ROPs and saves skilled workforce and time. The real-time audiovisual connection allows optimal supervision of imaging, provides excellent training opportunities, and connects ophthalmologists directly with the parents.

RESUMEN

PURPOSE: To analyze the outcomes of eyes treated for retinopathy of prematurity in posterior Zone I. METHODS: In a part retrospective (9 years) and part prospective (1 year) interventional study, we analyzed eyes treated for retinopathy of prematurity in posterior Zone I with a minimum follow-up for 6 months. RESULTS: This study included 109 eyes of 56 infants; mean gestational age and birth weights were 29.3 (±2.1) weeks and 1112.5 (±381.9) g, respectively. The treatment included intravitreal anti-vascular endothelial growth factor as the initial treatment modality in 101 eyes (92.6%), either alone (27 eyes) or combined with laser or vitreous surgery (73 eyes). Laser was the initial treatment modality in eight eyes, either alone (n = 3) or in combination with surgery (n = 5). With anti-vascular endothelial growth factor alone, 30.68% (n = 27) eyes responded favorably, and the remaining 69.32% (n = 59) eyes needed retreatment (laser in the majority). At the final follow-up, 89.9% (out of 109) of eyes did well anatomically. Good outcome was significantly linked to no detachment at presentation ( P < 0.0001) and the presence of well-defined central vascular trunks ( P = 0.001). CONCLUSION: Treating the eyes before retinal detachment with bevacizumab followed by laser (and surgery, if needed) results in a favorable outcome in babies with posterior Zone I retinopathy of prematurity.

RESUMEN

BACKGROUND: To analyze the clinical profile, presentation, possible pathophysiology, and outcomes of central retinal artery occlusion (CRAO) following blunt trauma in pediatric subjects. METHODOLOGY: The medical charts of subjects aged 18 years or less with a diagnosis of CRAO following blunt ocular trauma were analyzed retrospectively for demography, details of the trauma, ocular findings, additional imaging reports if any, and final outcome. A Medline search was done (key words like central retinal artery occlusion, blunt trauma, children, pediatric subjects, and adolescents) to gather information available in the literature on the subject. RESULTS: A total of 11 patients (11 eyes), mean age of 14.3 ± 3.4 years, and 100% male preponderance, with an average time duration from trauma to presentation to the hospital of 8.1 days were included. Visual acuity ranged from no light perception (four eyes) to finger count at a 1 m distance. Intraocular pressure was raised in three patients, of which two were suffering from sickle cell disease. In two eyes, the CRAO coexisted with optic nerve avulsion and the cilioretinal artery was spared. Disk pallor was seen in six eyes as early as 12 days from the trauma. None of the cases revealed any bony fracture in the CT scan. CONCLUSION: CRAO was observed to be an important primary or contributory cause of visual loss in children following blunt trauma, reflex vasospasm being the most common etiology. Early onset disk pallor could suggest an underlying vascular compromise of both retinal and optic disk circulation in addition to direct disk damage.

RESUMEN

Advent of pediatric handheld fundus cameras like RetCam, 3netra Forus, and Phoenix ICON pediatric retinal camera has aided in effective screening of retinopathy of prematurity (ROP), especially in countries with limited number of trained specialists. Recent advent of various smartphone-based cameras has made pediatric fundus photography furthermore affordable and portable. Future advances like ultra-wide field fundus cameras, trans-pars-planar illumination pediatric fundus camera, artificial intelligence, deep learning algorithm, and handheld SS-OCTA can help in more accurate imaging and documentation. This article summarizes the features of existing and upcoming imaging modalities in detail, including their features, advantages, challenges, and effectiveness, which can help in implementation of telescreening as a standard screening protocol for ROP across developing as well as developed countries.

RESUMEN

OBJECTIVE: To report the demographic profile and clinical characteristics of retinopathy of prematurity (ROP) in posterior Zone I. METHODS: In a partly retrospective (ten years) and partly prospective (one year) study, we analysed the demographic profile and clinical characteristics of babies with ROP in posterior Zone I. RESULTS: The study included 130 eyes of 67 infants with a mean gestational age and birth weight of 29.3 (±2.2) weeks and 1217.3 (±381.9) grams, respectively. All babies had received unblended oxygen. In 47 of 51 (91.1%) babies, the weekly weight gain was <100 g (details were not available in 16 babies). The ROP subtypes included aggressive, threshold, hybrid, stage 4, and atypical types in 78 (60%), 20 (15.4%), 11 (8.5%), 15 (11.5%), and 6 (4.6%) eyes, respectively. Fibrovascular proliferation, when present, was prominent nasally, occasionally overriding the disc margin. Extensive arteriovenous tortuosity was more prominent than vascular dilatation. Atypical observations included bleb-like detachment (6 eyes; 4.6%) and candle wax-like preretinal deposits (23 eyes; 17.7%). CONCLUSIONS: Retinopathy of Prematurity in posterior Zone I in this cohort was strongly associated with 100% unblended oxygen supplementation, poor weight gain, and multiple systemic co-morbidities. ROP in posterior zone 1 has a distinct profile with several atypical characteristics different from ROP in other zones.

RESUMEN

Purpose: We report clinical characteristics, risk factors, treatment outcomes, and prognostic predictors of post-vitrectomy secondary macular holes (MHs). Methods: This was a retrospective observational case series from November 2014 to December 2020. Eyes that developed secondary MH, two weeks and beyond after primary vitrectomy for non-MH indications, were enrolled. Pre- and intraoperative records were screened to exclude pre-existence of MH. Eyes with multiple vitreoretinal surgeries prior to MH detection and tractional myopic maculopathy were excluded. Results: A total of 29 eyes of 29 patients with a mean age of 52 years developed secondary MH post-vitrectomy. The most common indications for primary vitrectomy were rhegmatogenous retinal detachment (RRD, 48.2%) and tractional retinal detachment (TRD, 24.1%). Time to MH detection after primary vitrectomy was 91.5 ± 117.6 days. The mean minimum hole diameter was 530 ± 298 microns. Epi-retinal membrane and cystoid degeneration was noted in 6 (20.7%) and 12 (41.3%) eyes, respectively (p = 0.088). The mean time from MH detection to MH repair was 34 ± 42 days. The surgical intervention included internal limiting membrane peeling with tamponade in 25 eyes. Overall, 80% showed anatomic hole closure, 90.9% versus 57.1% in the RRD and TRD (p = 0.092), respectively. The mean best-corrected visual acuity (BCVA) at the final visit was 0.71 logarithm of the minimum angle of resolution. Thirteen eyes (52%) had a BCVA of 20/100 or better. Minimal hole diameter (p = 0.029) only predicted final visual acuity. The interval between MH diagnosis and repair did not affect hole closure significantly (p = 0.064). Conclusion: Secondary MH post-vitrectomy closed successfully with limited visual improvement and trails behind idiopathic MH.

RESUMEN

Purpose: To evaluate the effectiveness and future implications of COVID-related risk stratification for managing retinopathy of prematurity (ROP). Methods: A prospective study was conducted at a tertiary eye care center from the beginning of the lockdown in India from 23 March 2020 till the end of the first phase of lockdown on 29 May 2020. We evaluated 200 prematurely born infants (< 34 weeks of gestational age) using the new safety guideline protocols for low-risk babies developed in conjunction with the Indian ROP Society for care during the COVID-19 pandemic. Low risk included babies born at more than 30 weeks of gestational age, post menstrual age 34 weeks or above at presentation, more than 1000 grams of birth weight, and stable systemically with good weight gain. Results: New guidelines were implemented in 106 (53%) infants who were low risk while 94 (47%) infants with high risk were followed up as per the old guidelines. Out of the 106 infants (212 eyes) managed by the new guidelines, good outcome (group 1) was seen in 102 (96.2%) infants. Twenty-seven of the 102 infants had some form of ROP and 5 of these infants needed treatment. None of the low-risk babies with no detachment at presentation managed by new guidelines required surgery later (group 2). Two (1.9%) infants came with retinal detachment at presentation and underwent successful surgery (group 3) and two infants (1.9%) were lost to follow up. Conclusion: New risk stratification during the COVID-19 pandemic was an efficient and safe strategy in managing low-risk ROP babies.

RESUMEN

PURPOSE: To evaluate the causes of jet stream injury (JSI)-related iatrogenic retinal breaks (IRBs) during vitreoretinal surgery (VRS). METHODS: The precise surgical environment, which includes the indication and type of surgical procedure, retina status, details of instrumentation and fluidic parameters, and characteristics of the jet responsible for the IRB, was noted from case records. The nature of IRB and its healing and impact on anatomical and visual outcomes were analyzed. RESULTS: Five eyes of five patients with complete documentation of both the JSI and the IRB were included. Two cases were operated for macular hole, and one each for vitreous hemorrhage, retinal detachment, and endophthalmitis. One case had infusion-fluid-related JSI, while four developed it because of injection of surgical adjuncts (drugs, PFCL, and dye). JSI developed in two cases when the vitreous cavity was filled with fluid, while it was air-filled in three cases. In four cases, the fluid migrated into subretinal space, necessitating further maneuvers following which the breaks healed, but were directly responsible for vision loss in two cases. CONCLUSION: JSI related IRBs are rare but may be directly responsible for vision loss if they impact the macula. The balance between jet stream velocity, its distance from the retinal surface, the intervening media (vitreous cavity), and retinal health play an important role. It can occur because of both infusion as well as injection jets. Precautions must be taken in cases vulnerable to complications with suggested modifications in the surgical technique.

RESUMEN

Optical coherence tomography (OCT) is widely applied in diagnosis and management of retina diseases particularly macular diseases in adult retina practices. However, it has been under-utilized in pediatric retinal diseases especially in neonates and infants. Utilization of OCT in primary macular diseases in this age group is also uncommon and is less reported. Challenges involved in image acquisition and limitations with available devices technique can explain the limited research and accurate data availability in the literature in this field. Purpose of this review article is to summarize the use of OCT and its importance in various infantile retinal pathologies such as vascular diseases, tumors, retinal dystrophies, and optic nerve pathologies with primary focus on neonates and infants, along with infant choroid. In addition, we also discuss about future directions including OCT angiography for infants.

RESUMEN

Physicians have to play the role of a team leader and counselor and take written informed consent for high-risk surgeries in many cases. This is the first step toward initiating a mutually trustworthy relationship with the patient and family. The situation is more sensitive when vulnerable patients like small premature babies or the elderly are under consideration. In the event of a death, leadership and processes in place become extremely critical. We share our experience and practice pattern during this process, especially suited to India, but the broad principles would apply to most human situations. Hopefully, some of these can be incorporated into the existing training curriculum for team building and the art of effective physician-patient communication that should be intricately woven into the curriculum for the Science of Ophthalmic care.

RESUMEN

The outcome of a retinopathy of prematurity (ROP) program initiated in five districts of Odisha over 3 years with partnerships between the government and non-government organizations was prospectively analyzed. The mentoring partners trained the district ophthalmologists and neonatal care providers; the program was handed over when the trainees were considered competent enough to diagnose and treat babies with ROP. During the project period (July 2016-June 2019), 3058 babies were examined; ROP was detected in 33.81% (n = 1034) and 5.06% (n = 159) babies required treatment. At the end of the project, ROP screening was possible in all five districts, and treatment was possible in three districts. ROP care nodal centers were built in one government medical college. To strengthen the initial gain, we recommend creating an Odisha Retinopathy of Prematurity (OD-ROP) steering committee with private-public partnerships to support the program and monitor its progress in other districts of Odisha.

RESUMEN

PURPOSE: To compare retinal function by using fundus-guided microperimetry (MP) and multifocal electroretinography (mfERG) for detecting hydroxychloroquine (HCQ) maculopathy. METHODS: Forty-six eyes of 25 patients referred to our clinical practice for HCQ maculopathy assessment and 3 groups of normal control subjects were evaluated by mfERG and MP. Macular structure was assessed using spectral-domain optical coherence tomography (SD-OCT). Ring ratios from the three innermost mERG rings were compared with average sensitivity of each MP ring at approximately equivalent distances from the fovea. HCQ toxicity was defined as an mfERG ring ratio or mean MP ring sensitivity >2 standard deviations below the normal mean. The sensitivity and specificity of MP to detect HCQ toxicity relative to mfERG were evaluated. RESULTS: MP rings MR2 and MR3 were positively correlated with corresponding mfERG ring ratios (r = 0.52, P = 0.002 and r = 0.56, P < 0.001 respectively). Ring 2 and ring 3 measures of MP and mfERG were significantly worse in HCQ eyes than controls (P < 0.001). The sensitivity of MP to detect toxicity for MR1 through MR3 ranged from 33% to 88%, whereas specificity ranged from 72% to 85%. Through rings 1 to 3, the frequency of abnormal function ranged from 20% to 48% for MP, 11% to 35% for mfERG, and 41% to 45% for SD-OCT. CONCLUSIONS: The frequency of detection of HCQ toxicity with MP was greater than with mfERG. MP showed an overall good sensitivity and moderate specificity in detecting HCQ-induced functional deficits. TRANSLATIONAL RELEVANCE: Results from this study may allow clinicians to improve screening accuracy for HCQ toxicity by using the alternative modality of MP.

RESUMEN

Purpose. To document the changing clinical presentation of diabetic retinopathy (DR) over a decade, the current knowledge-attitude-practice (KAP) of known type 2 diabetes mellitus (DM) patients, and the current vision related quality of life (VR-QOL) of patients with DR in a tertiary eye care center in Eastern India. Methods. Two hundred and forty patients with known type-2 DM were evaluated. The evaluation included status of DR (n = 240), KAP (n = 232), and VR-QOL (n = 75). International classification of DR was used in the study. The DR status was compared with another cohort (n = 472) examined a decade earlier, in year 2001. The KAP-25 questions were designed after literature review. The National Eye Institute Visual Function Questionnaire (NEI-VFQ; including optional items) was validated by Rasch analysis. Both KAP and VR-QOL were analyzed according to degree of DR, duration of known DM, and educational qualification. Results. Average age of the current cohort (n = 240) was 57.16 ± 9.03 years; there were 205 (85.4%) male patients and 143 (59.6%) patients had received less than graduate qualification. The mean duration of DM since diagnosis was 10 ± 7.8 months (range 8 months to 30 years); 118 (49.16%) patients had DR. In a decade time, 2001 to 2011, there was a change of retinopathy status at presentation (more often nonproliferative diabetic retinopathy, NPDR). One-third of NPDR patients had poor vision and half of them were hypertensive. KAP was better in patients with higher education and those having DR. VFQ score was higher in better seeing patients. Conclusion. Patients currently presenting at earlier stage of retinopathy are probably related to poor vision. Early detection and treatment of DR is likely to preserve and/or improve vision.

RESUMEN

PURPOSE: To determine the feasibility and safety of bilateral simultaneous vitreoretinal surgery in pediatric patients. DESIGN: International, multicenter, interventional, retrospective case series. PARTICIPANTS: Patients 17 years of age or younger from 24 centers worldwide who underwent immediate sequential bilateral vitreoretinal surgery (ISBVS)-defined as vitrectomy, scleral buckle, or lensectomy using the vitreous cutter-performed in both eyes sequentially during the same anesthesia session. METHODS: Clinical history, surgical details and indications, time under anesthesia, and intraoperative and postoperative ophthalmic and systemic adverse events were reviewed. MAIN OUTCOME MEASURES: Ocular and systemic adverse events. RESULTS: A total of 344 surgeries from 172 ISBVS procedures in 167 patients were included in the study. The mean age of the cohort was 1.3±2.6 years. Nonexclusive indications for ISBVS were rapidly progressive disease (74.6%), systemic morbidity placing the child at high anesthesia risk (76.0%), and residence remote from surgery location (30.2%). The most common diagnoses were retinopathy of prematurity (ROP; 72.7% [P < 0.01]; stage 3, 4.8%; stage 4A, 44.4%; stage 4B, 22.4%; stage 5, 26.4%), familial exudative vitreoretinopathy (7.0%), abusive head trauma (4.1%), persistent fetal vasculature (3.5%), congenital cataract (1.7%), posterior capsular opacification (1.7%), rhegmatogenous retinal detachment (1.7%), congenital X-linked retinoschisis (1.2%), Norrie disease (2.3%), and viral retinitis (1.2%). Mean surgical time was 143±59 minutes for both eyes. Higher ROP stage correlated with longer surgical time (P = 0.02). There were no reported intraoperative ocular complications. During the immediate postoperative period, 2 eyes from different patients demonstrated unilateral vitreous hemorrhage (0.6%). No cases of endophthalmitis, choroidal hemorrhage, or hypotony occurred. Mean total anesthesia time was 203±87 minutes. There were no cases of anesthesia-related death, malignant hyperthermia, anaphylaxis, or cardiac event. There was 1 case of reintubation (0.6%) and 1 case of prolonged oxygen desaturation (0.6%). Mean follow-up after surgery was 103 weeks, and anatomic success and globe salvage rates were 89.8% and 98.0%, respectively. CONCLUSIONS: This study found ISBVS to be a feasible and safe treatment paradigm for pediatric patients with bilateral vitreoretinal pathologic features when repeated general anesthesia is undesirable or impractical.

RESUMEN

BACKGROUND: This study aims to determine the stability, sterility and safety of bevacizumab multiple dosing from a single vial without prior aliquoting. METHODS: In-vitro and human study. Six bevacizumab vials, used in multiple patients on a single day by direct withdrawal from the vial, and stored in 4°C up to a variable period, were tested for stability (high-performance liquid chromatography; [HPLC]), sterility (culture), conformational stability by circular dichroism and fluorescence spectroscopy and the rubber cork structural integrity (electron microscopy [EM]). RESULTS: HPLC of all six samples of used bevacizumab and the control bevacizumab sample were similar; culture was negative; and the EM of rubber corks did not show an open communication. Spectroscopic studies indicated drug conformational stability. Further, there was no infection or inflammation in 221 consecutive patients (973 injections) when bevacizumab was stored at 4°C and used for one week. CONCLUSION: Bevacizumab does not lose stability when stored at 4°C. It may be used for a week by direct withdrawal from the vial without fear of infection or inflammation if all standard precautions related to intravitreal injection are adhered to.

RESUMEN

BACKGROUND & OBJECTIVES: Geographical variations are known to influence different aspects of endophthalmitis. We report the epidemiological, clinical and microbiological profile of patients with infectious endophthalmitis presented to a tertiary eye care centre in Odisha, India, and compare the results with published reports from other parts of India. METHODS: Retrospective review of medical records of 107 patients, seen between December 2006 and January 2009 was done. All patients had undergone parsplana vitrectomy with intraocular antibiotics and the management was based on microbiological analysis of the vitreous fluid. RESULTS: Forty six (43.0%) patients had post-operative (PO), 43 had post-traumatic (PT) and 18 (16.8%) had endogenous (EG) endophthalmitis. Males were predominant in all three types of endophthalmitis. Significantly younger individuals constituted PT group. While culture established microbial diagnosis in 45 patients (42%), direct microscopy was positive in 38 patients (35.5%). Fungal aetiology was found in 13 patients (PO-7, PT-4, EG-2) and bacteria accounted for 32. Similar to studies from north, central and south India, fungi and Gram-negative bacteria accounted for a large number of PO endophthalmitis cases. Two PT patients had polymicrobial infection. All Gram-positive bacteria were susceptible to vancomycin. Susceptibility to ceftazidime was variable among the Gram-negative bacteria. Best corrected visual acuity (BCVA) at presentation was less than 20/200 in majority (93%) of the patients. While the treatment outcome was variable in fungal and sterile endophthalmitis, the BCVA was either unchanged or improved in 100 per cent of bacterial endophthalmitis patients. INTERPRETATION & CONCLUSIONS: The spectrum of infection and outcome of infectious endophthalmitis in Odisha was similar to other parts of the country. Fungi and bacteria were involved in all three types of endophthalmitis. Empirical use of standard intravitreal therapy is recommended while emphasizing on vitreous biopsy for culture and sensitivity whenever possible.

RESUMEN

PURPOSE: To study the optical coherence tomography (OCT) patterns in optic disc pit maculopathy and retinal changes after vitreous surgery. MATERIALS AND METHODS: Retrospective review of consecutive cases with optic disc pit maculopathy seen at two tertiary eye institutes from January 2005 to June 2009. RESULTS: Twenty-four eyes of 23 patients are included. The presenting visual acuity ranged from 20/400 to 20/20 (median:20/80). The median age at presentation was 24 years (range, 6-57 years). Optical coherence tomography demonstrated a combination of retinoschisis and outer layer detachment (OLD) in 19 (79.17%) eyes, OLD only in 3 (12.5%) eyes and retinoschisis only in 2 (8.33%) eyes. An obvious communication (outer layer hole) between the schisis and OLD was seen in 14 (73.68%) of the 19 eyes with both features. Of the 21 eyes with retinoschisis, schisis was present in multiple layers in 15 (71.43%) and single layer in 6 (28.57%) eyes. Eleven eyes underwent pars plana vitrectomy including creation of posterior vitreous detachment (PVD), fluid-air exchange, low intensity laser photocoagulation at the temporal edge of the optic disc pit and non-expansile perfluoropropane gas (14%) injection. Five (45.45%) of 11 eyes undergoing vitrectomy had complete resolution and 4 (36.36%) eyes had partial resolution of maculopathy. Visual acuity improved in 8 (72.72%) of 11 eyes. CONCLUSION: Optical coherence tomography demonstrates multiple layer schisis and outer layer detachment as main features of optic disc pit maculopathy. Vitrectomy with PVD induction, laser photocoagulation and gas tamponade results in anatomical and visual improvement in most cases with optic disc pit maculopathy.

RESUMEN

An 11-month-old boy presented with bilateral vision loss following upper respiratory tract infection. Extensive perivascular sheathing resembling frosted branch angiitis and severe macular edema was noted in both eyes. All tests for etiological diagnosis were negative. Treatment with systemic corticosteroids and antibiotics caused resolution of perivascular infiltrates. Macular edema resolved with improvement in visual acuity following consecutive bilateral intravitreal triamcinolone acetonide injections. To our knowledge, this is the youngest reported case of frosted branch angiitis.
