Seasonal Hyperacute Panuveitis (SHAPU) in Bhutan.

PURPOSE: To report the first series of Seasonal Hyperacute Pan Uveitis (SHAPU) from Bhutan. METHODS: We retrospectively analyzed the patients with clinically diagnosed SHAPU treated in the referral center in the last 5 years. Data included demographics (age, sex, laterality), region, time of presentation (year, season) and treatment received. RESULTS: The series included 3 males and 2 females. The mean age was 16 years. Three patients had presented in autumn of 2021, and two in autumn of 2019. Four patients presented within 2 weeks of the onset of symptoms. All patients had either exposure or contact with white moths. All patients presented with unilateral sudden painless reduction in vision and low Intraocular pressure. Four patients required vitrectomy. The final visual acuity of 3 patients was >6/36, and one patient was 6/60. CONCLUSIONS AND IMPORTANCE: The time of presentation and early treatment intervention are crucial in achieving good visual prognosis in SHAPU.

Color fundus imaging in retinopathy of prematurity screening: Present and future.

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.

Electronic medical records driven big data analytics in retinal diseases, report number 1: non-oncological retinal diseases in children and adolescents in India.

PURPOSE: To describe the spectrum and demographic distribution of non-oncological retinal diseases in children and adolescents presenting to a multi-tier ophthalmic hospital network in India. METHODS: This is a cross-sectional hospital-based retrospective study over nine years (March 2011-March 2020) from a pyramidal eye care network in India. The analysis included 477,954 new patients (0-21 years), collected from an International Classification of Diseases (ICD) coded electronic medical record (EMR) system. Patients with a clinical diagnosis of retinal disease (non-oncological) in at least one eye were included. Age-wise distribution of these diseases in children and adolescents was analysed. RESULTS: In the study, 8.44% (n = 40,341) of new patients were diagnosed with non-oncological retinal pathology in at least one eye. The age group-specific distribution of retinal diseases was 47.4%, 11. 8%, 5.9%, 5.9%, 6.4%, 7.6% in infants (< 1 year), toddlers (1-2 years), early childhood (3-5 years), middle childhood (6-11 years), early adolescents (12-18 years) and late adolescents (18-21 years), respectively. 60% were male, and 70% had bilateral disease. The mean age was 9.46 ± 7.52 years. The common retinal disorders were retinopathy of prematurity (ROP, 30.5%), retinal dystrophy (19.5%; most commonly, retinitis pigmentosa), and retinal detachment (16.4%). Four-fifth of the eyes had moderate to severe visual impairment. Nearly one-sixth of patients needed low vision and rehabilitative services, and about 1 in 10 patients required surgical intervention (n = 5960, 8.6%). CONCLUSION AND RELEVANCE: About 1 in 10 children and adolescents seeking eye care in our cohort had non-oncological retinal diseases; the common ones were ROP (in infants) and retinitis pigmentosa (in adolescents). This information would help future strategic planning of eye health care in the institution in pediatric and adolescent age groups.

Clinical presentation and treatment outcomes of an algorithmic approach to uveal effusion syndrome.

Purpose: To describe the clinical features and treatment outcomes in spontaneous uveal effusion syndrome (UES). Methods: A 10-year retrospective chart review of UES patients from a tertiary eye center was carried out. Optical coherence tomography (OCT), fundus fluorescein angiography, and ultrasound biomicroscopy (UBM) scans were performed. UES was managed based on presenting best-corrected visual acuity (BCVA), symptoms, and fundus findings. Patients with secondary causes of uveal effusion were excluded. Results: Twenty-five eyes of 16 patients were included. Of the 16 patients, 14 (88%) were male and 9 (56%) had bilateral disease. Fifteen of 25 affected eyes had nanophthalmos (axial length (AL) <20.5 mm) and 6 had hyperopia with AL >20.5 mm. The presenting mean distance BCVA was 0.74 ± 0.64 logMAR (mean Snellen: 20/100). Eleven eyes had exudative retinal detachment, and 4 also had exudative choroidal detachment (CD). Choroidal thickness (CT) was increased in 11 eyes on B-scan ultrasonography, and the mean CT was 1.74 ± 0.38 mm. Sub-retinal fluid (SRF) and retinal folds were the most common OCT findings. UBM findings included shallow angles, peripheral CD, and supra-ciliary effusion. A combination of local and systemic corticosteroids was used to successfully treat 12 eyes, 6 needed surgery, and 7 were observed. Partial sclerectomy with anterior chamber maintainer-assisted SRF drainage was the favored surgery. The median period of follow-up was 6.5 months (0.1-76 months), and the mean distance BCVA at the last follow-up was 0.58 ± 0.42 logMAR (mean Snellen: 20/80). Conclusion: UES can be suitably managed both medically and surgically based on clinical presentation.

It is time for more colors!

Retinal drawing with a color-coding system brings uniformity in representation of fundus findings so that clinician can decipher various lesions on a two-dimensional drawing. Existing color coding addresses most of the common retinal pathologies including preretinal, intraretinal, and subretinal lesions. However, with the advent of various imaging modalities there is deeper understanding of microanatomy of retina and associated pathologies. With this, there appears further need of newer set of color coding to include the minute details of fundus findings clinically. Through this article, we discuss few common pathologies at different levels of retina layers with color-coding dilemma which calls for a better preciseness in its clinical representations.

Effectiveness and future implications of COVID-19-related risk stratification for managing retinopathy of prematurity: The Indian twin cities retinopathy of prematurity study report number 10.

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.

Evaluation of a revised care plan for babies with retinopathy of prematurity during SARS-CoV-2 pandemic in India.

Purpose: To analyze the impact of a revised care plan for retinopathy of prematurity (ROP) during SARS-CoV-2 pandemic in a tertiary eye care facility in eastern India. Methods: In a retrospective study, we analyzed the medical records of babies managed for ROP during the peak of the SARS-CoV-2 pandemic, with particular reference to the challenges, and the revised strategies addressing travel restrictions for five months, from April to August 2020. The strategy included selective referral (babies with higher treatment probability), longer follow-up intervals (babies with non-alarming findings), use of locally available workforce, and teleconsultation whenever feasible. Results: In the given period, 222 babies were examined versus 624 in the preceding year (P = 0.001). The average gestational age, birth weight, and postmenstrual age at presentation were 30.4 weeks, 1.31 kg, and 37.7 weeks, respectively. The first examination was on time in 40.1% of babies but was delayed by a median of 23 days in the remaining babies. In the cohort, 56.7% of babies had any ROP, and 27.9% required treatment (versus 8.8% in the previous year; P < 0.001). The intravitreal anti-vascular growth factor (anti-VEGF) injection was more often used than in the previous year (n = 72 vs 36; P < 0.0001). The treatment outcome was comparable before and after the SARS-CoV-2 lockdown period. There was no report of health issues among the care providers attributable to ROP care. Conclusion: The revised strategy resulted in a smaller pool of babies screened but a larger proportion of babies treated for ROP. This strategy could be used more profitably in future ROP care.

Exudative retinal detachment as an initial presentation of retinopathy of prematurity: Clinical profile and outcomes of a rare presentation.

Purpose: To describe the clinical profile and treatment outcomes of infants with retinopathy of prematurity (ROP) presenting with isolated exudative retinal detachment (ERD). Methods: Retrospective interventional case series. Preterm infants diagnosed with ROP with ERD at presentation were included. All demographic details, clinical findings, and treatment given were documented. The anatomical outcome was categorized as good, fair, and poor. Refractive outcome was classified into mild, moderate, and severe according to spherical equivalent at the last visit. Results: Fifteen eyes (8 patients) were included. Mean gestational age was 31.3 weeks, and birth weight was 1462.6 g. All eyes presented with aggressive ROP. Patches of retinal edema in avascular retina were seen in all eyes. A total of 86.6% of eyes had vascular sclerosis while 86.6% of eyes had subretinal exudates. The anatomical outcome was good in all eyes. In addition, 40% of eyes had a mild refractive error. Conclusion: Exudative retinal detachment in ROP is rare. The use of unregulated oxygen can be a contributory factor. Vascular sclerosis is consistent with hyperoxia-induced retinopathy models. Retinal edema and subretinal exudates indicate disrupted inner and outer blood-retinal barrier. Treatment outcomes are good when diagnosed and treated in time.

A retrospective analysis of ultra-widefield photograph (Optos) documentation of retinopathy of prematurity at a tertiary eye care outpatient setup: the Indian Twin Cities ROP Study, report number 11.

PURPOSE: To demonstrate the usefulness of ultrawide-field fundus (UWF) photography for documentation in retinopathy of prematurity (ROP). METHODS: The medical records of infants with ROP who underwent at least one sitting of UWF fundus photography in addition to binocular indirect ophthalmoscopy (BIO) from April 2018 to September 2020 were analyzed retrospectively. BIO was conducted by a trained ROP specialist, and final diagnosis and treatment were based solely on BIO findings. All fundus photographs were captured on Optos UWF camera (Dunfermline, UK) in a flying baby position. Demographic details and fundus findings on BIO and fundus photographs were analyzed. RESULTS: Of the 187 infants who met inclusion criteria for successful imaging, 22 (11.7%) had findings that were discordant with BIO. Although no posterior disease was missed, 4 infants who received treatment would not have been treated based solely on UWF photography findings. Of the 60 babies whose images did not meet the inclusion criteria for successful imaging, 41 had ROP that required intervention. CONCLUSIONS: In our patient cohort, UWF photography proved useful in documenting the initial and follow-up findings of preterm babies with ROP.

OCT Imaging in Infants.

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.

Compassionate and standard operating procedure-based counseling and practice are essential in high-risk infantile anesthesia and managing death in eye surgery.

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.

Imaging the pediatric retina: An overview.

Recent decade has seen a shift in the causes of childhood blinding diseases from anterior segment to retinal disease in both developed and developing countries. The common retinal disorders are retinopathy of prematurity and vitreoretinal infections in neonates, congenital anomalies in infants, and vascular retinopathies including type 1 diabetes, tumors, and inherited retinal diseases in children (up to 12 years). Retinal imaging helps in diagnosis, management, follow up and prognostication in all these disorders. These imaging modalities include fundus photography, fluorescein angiography, ultrasonography, retinal vascular and structural studies, and electrodiagnosis. Over the decades there has been tremendous advances both in design (compact, multifunctional, tele-consult capable) and technology (wide- and ultra-wide field and noninvasive retinal angiography). These new advances have application in most of the pediatric retinal diseases though at most times the designs of new devices have remained confined to use in adults. Poor patient cooperation and insufficient attention span in children demand careful crafting of the devices. The newer attempts of hand-held retinal diagnostic devices are welcome additions in this direction. While much has been done, there is still much to do in the coming years. One of the compelling and immediate needs is the pediatric version of optical coherence tomography angiography. These needs and demands would increase many folds in future. A sound policy could be the simultaneous development of adult and pediatric version of all ophthalmic diagnostic devices, coupled with capacity building of trained medical personnel.

Exudative retinal detachment as an initial presentation in retinopathy of prematurity.

Exudative retinal detachment as the initial presentation of retinopathy of prematurity is extremely rare. We present 2 such cases with extensive subretinal exudation, ischemia and exudative retinal detachment. Both were managed successfully with a combination of intravitreal anti- vascular endothelial growth factor injection and laser photocoagulation.
