RESUMEN

BACKGROUND: Sickle cell disease (SCD) is the commonest inherited blood disorder leading to complications occurring due to vaso-occlusion including sight-threatening retinopathy. Retinopathy can be managed if diagnosed early and vision loss can be prevented. Since, very less data are available from India, hence, this study was conducted in children (7-18 years) with SCD to diagnose retinopathy by using ocular coherence tomography (OCT) in subclinical stages. METHODS: This cross sectional single-center study was performed in 7-18 years age group children with SCD without any visual symptoms. Enrolled participants underwent complete ophthalmological examination including macula and optic disc thickness measurements using Cirrus HD-OCT and results were analyzed. RESULTS: Among 55 participants, none had visual impairment. Significant fundoscopy finding (nonproliferative sickle cell retinopathy/NPSR) was found in three patients (5.4%), thinning of central macula in four patients (7.27%), inner macula thinning in eight patients (14.5%), outer macula thinning in one patient (1.81%), retinal nerve fiber layer thinning in five patients (9%), ganglion cell layer to inner plexiform layer thinning in eight patients (14.54%). Overall NPSR was found in 5.4% patients detected with fundoscopy, whereas retinal layer thinning was found in 14 patients (25.4%) using OCT. CONCLUSION: Despite of the significant prevalence of SCR, it is still underdiagnosed complication, leading to thinning of the retina from early ages; thus, its early diagnosis by regular screening using newer diagnostic methods can prevent progression to sight-threatening complications and provide better quality of life for these patients.

RESUMEN

PURPOSE: To report a series of five cases with retinitis following episodes of febrile illness, its evaluation, management and outcome. METHOD: Retrospective, consecutive case series of five patients presenting with acute retinitis, following a febrile illness. RESULTS: The retinal lesions had a sudden onset with rapid evolution, preceded by a febrile episode within one month of presentation, in all cases. Extensive serology and PCR testing were non-contributory toward identifying the etiology and guiding therapy. Systemic corticosteroid therapy was effective in hastening the resolution of lesions. CONCLUSION: Post-fever retinitis appears to be a distinct clinical form of acute hemorrhagic non-necrotizing retinitis without a uniformly identifiable cause, and some evidence pointing toward a para-infectious etiology secondary to flu-like illnesses. With an unusual morphological presentation and annual seasonal patterns in the endemic areas, it is important to differentiate this entity, from other forms of infectious retinitis, before initiating corticosteroid therapy.

RESUMEN

PURPOSE: To report the outcomes of a novel technique of scleral debridement in five consecutive cases of relentlessly progressive and fulminant infectious scleritis following corticosteroid exposure. METHODS: Five consecutive patients of infectious scleritis with a common history of corticosteroids exposure, resulting from either an initial misdiagnosis of autoimmune scleritis or as anti-inflammatory adjunct to specific antimicrobial therapy. Data collection included presentation details such as photographs, clinical findings, microbiological analysis, treatment details and audit of surgical videos. Cases with undisputed diagnosis of infectious scleritis with microbiological evidence, without corticosteroid use, were excluded from  the study. RESULTS: After full-thickness scleral debridement and cessation of corticosteroids, favourable anatomical and visual outcome was observed in all cases; however, two patients required multiple scleral debridements due to progressive scleritis. Scleral patch graft was not used in any case. Microbiology detected infective organisms in two cases, while the remaining revealed negative results. Therefore, specific antimicrobial therapy was initiated in former, whereas empirical broad-spectrum regimen in patients with repeatedly negative microbiological results. No recurrence of scleritis or development of ciliary staphyloma was noted and anatomical integrity was maintained with normal intraocular pressure during follow-up. CONCLUSION: This study highlights the fulminant and relentlessly progressive clinical course, that infectious scleritis can metamorphose into, despite specific antimicrobial therapy, if inadvertent corticosteroid therapy is administered. Full-thickness debridement without scleral patch graft, could achieve elimination of infectious foci, with favourable long-term anatomical and visual outcome. This technique could offer a potential last-resort approach in such cases where standard therapeutic modalities have not been successful.

RESUMEN

Uveitis is a spectrum of inflammatory disorders characterized by ocular inflammation and is one of the leading causes of preventable visual loss. The main aim of the treatment of uveitis is to control the inflammation, prevent recurrences of the disease and preserve vision while minimizing the adverse effects associated with the therapeutic agents. Initial management of uveitis relies heavily on the use of corticosteroids. However, monotherapy with high-dose corticosteroids is associated with side effects and cannot be maintained long term. Therefore, steroid-sparing agents are needed to decrease the burden of steroid therapy. Currently, the therapeutic approach for non-infectious uveitis (NIU) consists of a step-ladder strategy with the first-line option being corticosteroids in various formulations followed by the use of first-, second- and third-line agents in cases with suboptimal steroid response. Unfortunately, the agents currently at our disposal have limitations such as having a narrow therapeutic window along with their own individual potential side-effect profiles. Therefore, research has been targeted to identify newer drugs as well as new uses for older drugs that target specific pathways in the inflammatory response. Such efforts are made in order to provide targeted and safer therapy with reduced side effects and greater efficacy. Several specially designed molecular antibodies are currently in various phases of investigations that can potentially halt the inflammation in patients with NIU. In the review, we have provided a comprehensive overview of the current and upcoming therapeutic options for patients with NIU.

RESUMEN

IMPORTANCE: In a subset of patients with retinal vasculitis, there is occlusion of blood flow through the retinal vessels. These eyes are at high risk of sight-threatening complications. BACKGROUND: To characterize epidemiology, clinical course, treatment and outcomes of occlusive retinal vasculitis (ORV). DESIGN: Retrospective study PARTICIPANTS: Seventy-seven uveitis patients with ORV at two large tertiary-care institutions (the USA and India). METHODS: Out of 2438 patients screened, 346 patients were diagnosed with retinal vasculitis of which 77 patients (96 eyes) were diagnosed with ORV. Patients with ORV (capillary, arteriolar and/or venular) were further analysed. Diagnostic criteria for occlusive vasculitis included (i) absence of blood flow in vessels (arterioles, venules and/or capillaries), (ii) capillary non-perfusion areas and/or arteriolar-venous anastomosis and (iii) intraretinal haemorrhages, cotton-wool spots or vitreous haemorrhage. MAIN OUTCOME MEASURES: Best-corrected visual acuity, treatment and complications. RESULTS: The mean age was 32.09 ± 13.51 years. Most common aetiologies were tuberculosis and Adamantiades-Behçet's disease in India and systemic lupus erythematosus in the USA. Best-corrected visual acuity improved from 0.38 ± 0.30 logMAR (20/48 Snellen equivalent) (baseline) to 0.25 ± 0.30 (20/35 Snellen equivalent) at final visit (P < 0.0001). Vitreous haemorrhage was seen in 31.08% eyes. Pars plana vitrectomy was performed in 12.16% eyes. Therapy with systemic steroids was required in 78.48% patients. In addition, 46.75% patients required immunomodulators and/or biologics. CONCLUSIONS: Occlusive retinal vasculitis is caused by heterogeneous group of uveitides depending upon the geographic location. It is imperative to identify eyes with ORV as they are predisposed to complications requiring aggressive therapy.

RESUMEN

BACKGROUND: To study morphological features of optic disc venous collaterals (OVCs) and neovascularization of optic disc (NVD) on optical coherence tomography angiography (OCTA). METHODS: Patients with OVCs and NVDs secondary to ischemic retinal diseases were prospectively enrolled. Multimodal imaging was performed using color fundus photography, fluorescein angiography (FA), and OCTA. Morphological evaluation of en-face structural OCT, cross-sectional and en-face OCTA was performed. RESULTS: Twenty eyes (20 patients; OVCs: n = 10 and NVD: n = 10) were included. OVCs appeared as small, loopy vessels distinct from surrounding peripapillary capillaries on OCTA in the radial peripapillary capillary frame. NVDs appeared as a mesh of fine caliber, raised vessels best seen in the vitreous slab of OCTA. Flow signals in these vascular alterations correlated well with hyperfluorescence on FA. CONCLUSIONS: OCTA provides improved visualization of NVDs and OVCs in ischemic retinal diseases such as diabetic retinopathy and retinal vein occlusions compared to conventional FA.

RESUMEN

BACKGROUND: Decreased intra-ocular pressure after cataract surgery has been reported in eyes with and without glaucoma with variable magnitude. It is influenced by the anatomical structure of the anterior chamber. Preoperative evaluation of anterior chamber parameters can help to predict the change in intra-ocular pressure postoperatively. OBJECTIVE: The objective of the study is to evaluate intraocular pressure (IOP) change after uneventful phacoemulsification in non-glaucomatous eyes with open angles and its correlation with preoperative anterior chamber parameters measured by anterior segment optical coherence tomography (AS-OCT). METHODS: In this hospital-based prospective observational study, we included consecutive patients without glaucoma and open angles on gonioscopy who had undergone uncomplicated phacoemulsification with intraocular lens implantation (IOL). IOP and anterior chamber biometric parameters were measured preoperatively and compared with parameters obtained three months post-operatively by AS-OCT. The change in IOP and its relation to the parameters, including anterior chamber angle (ACA), anterior chamber depth (ACD), angle opening distance 500 µm anterior to the scleral spur (AOD500), anterior chamber width (ACW), lens vault (LV), and trabecular iris space area (TISA500) were evaluated. The main outcome measure was a change in IOP after phacoemulsification in normal eyes. RESULTS: Sixty-four eyes of 64 patients were enrolled. The mean patient age was 58.5 ± 9.4 years. The average IOP reduction was 2.43±1.64 mm of Hg from a preoperative mean of 16.77±2.54 mmHg three months after phacoemulsification surgery. The mean AOD500 increased significantly (0.440 ± 0.07 to 0.522 ±0.092) from preoperatively to three months postoperatively (p < 0.001). Preoperative lens vault and preoperative IOP had a strong positive correlation with the change in IOP at three months (r-value = 0.606; p-value <0.001) and (r-value = 0.73; p-value <0.001). There was a significant negative correlation between pre-operative TISA and AOD with change in IOP at three months (r-value = -0.545; p-value <0.001) and (r-value = -0.69; p-value <0.01). CONCLUSION:  Phacoemulsification surgery results in IOP reduction in non-glaucomatous eyes. Pre-operative IOP, lens vault, AOD, and TISA were significant predictors for IOP reduction.

RESUMEN

Purpose: The primary objective of the study was to assess the macular retinal vessel density, subfoveal choroidal thickness, and retinal layer metrics by optical coherence tomography angiography (OCTA), enhanced-depth imaging optical coherence tomography (EDI-OCT), and spectral domain optical coherence tomography (SD-OCT), respectively, in recovered COVID-19 patients and its comparison with the same in control subjects. The secondary objective was to evaluate differences in OCTA parameters in relation with the severity of COVID-19 disease and administration of corticosteroids. Methods: A case-control study was performed that included patients who had recovered from COVID-19 and age-matched healthy controls. Complete ocular examination including OCTA, SD-OCT, and EDI-OCT were performed three months following the diagnosis. Results: Three hundred sixty eyes of 180 subjects were enrolled between the two groups. A decreased mean foveal avascular zone area in both superficial capillary plexuses (P = 0.03) and deep capillary plexuses (P < 0.01), reduced average ganglion cell layer-inner plexiform layer thickness (P = 0.04), and increased subfoveal choroidal thickness (P < 0.001) were observed among cases in comparison to the control group. A significant correlation was found between sectoral macular vessel density in relation to disease severity and a decrease in vessel density with greater severity of the disease. Conclusion: OCTA detected retinal microvascular alterations following SARS-CoV-2 infection in subjects with the absence of any clinical ocular manifestation or systemic thrombotic events. These parameters could be used to help identify patients with a higher incidence of systemic thromboembolism on longer follow-ups and identify the impact of corticosteroids on retinal architecture.

RESUMEN

Purpose: To study the epidemiological pattern, prevalence, types, and correlates of age-related cataracts in a tertiary care center in central India. Methods: This hospital-based single-center cross-sectional study was conducted on 2,621 patients diagnosed with cataracts for 3 years. Data pertaining to demography, socio-economic profile, cataract grading, cataract types, and associated risk factors were evaluated. Statistical analysis using unadjusted odds ratio (OR) and multivariate logistic regression was performed, with P-value <0.05 considered significant with the power of the study being 95%. Results: The commonest age group affected was 60-79 years, closely followed by the 40-59 years age group. The prevalence of nuclear sclerosis (NS), cortical (CC), and posterior subcapsular cataract (PSC) was found to be 65.2% (3,418), 24.6% (1,289), and 43.4% (2,276), respectively. Among mixed cataracts, (NS + PSC) had the highest prevalence of 39.8%. Smokers were found to have 1.17 times higher odds of developing NS than non-smokers. Diabetics had 1.12 times higher odds of developing NS cataracts and 1.04 times higher odds of developing CC. Patients with hypertension showed 1.27 times higher odds of developing NS and 1.32 times higher odds of developing CC. Conclusion: The prevalence of cataracts in the pre-senile age group (<60 years) was found to have increased significantly (35.7%). A higher prevalence of PSC (43.4%) was found in studied subjects, as compared to the data of previous studies. Smoking, diabetes, and hypertension were found to have a positive association with a higher prevalence of cataracts.

RESUMEN

An intracameral (IC) injection directly delivers the drug into the anterior chamber of the eye. This targeted drug delivery technique overcomes the ocular barriers and offers a high therapeutic concentration of medication at the desired site and consequently better clinical outcomes. IC drug delivery is a safe and effective modality with many advantages over topical delivery. These include excellent bioavailability, reduced systemic risk, and minimal ocular toxicity. Agents delivered via IC injection have shown promising results against infection, inflammation, ocular hypertension, and neovascularization. Current literature shows that IC antibiotics, including cefuroxime, vancomycin, and moxifloxacin, are routinely used for prophylaxis of endophthalmitis. Other drugs available for IC use are steroids, anesthetics, mydriatics, miotics, antivascular endothelial growth factor, antiglaucoma, and alkylating agents. Introduction of sustained-release devices containing dexamethasone or Bimatoprost in anterior chamber via IC route has the potential in treating ocular inflammation and raised intraocular pressure. The complications such as hemorrhagic occlusive retinal vasculitis and toxic anterior segment syndrome have been documented with IC prophylaxis but are rare. In this review, we provide an overview of available IC drugs, their pharmacokinetics, the spectrum of activity, dosage and preparation, prophylactic and therapeutic usage, clinical efficacy, and safety profiles.

RESUMEN

This study aimed to review the current literature for epidemiology, pathogenesis, clinical spectrum and management of rhino-orbito-cerebral-mucormycosis (ROCM), especially highlighting the association between ROCM and COVID-19 disease and factors resulting in its resurgence during the pandemic. Mucormycosis is a rare, but an important emerging opportunistic fungal infection, often associated with high morbidity and mortality. ROCM is the commonest and also the most aggressive clinical form occurring in debilitated patients in conjunction with sinus or para-sinus involvement due to the propensity for contiguous spread. Recently ROCM has shown an unprecedented resurgence during the current pandemic. Reports from different parts of the world indicated an increased risk and incidence of ROCM in patients who had required hospital admission and have recovered from moderate-to-severe COVID-19 disease. A majority of mucormycosis cases have been reported from India. The presence of diabetes mellitus (DM) and use of corticosteroids for COVID-19 pneumonia were found to be the key risk factors, resulting in higher mortality. Amidst the ongoing pandemic, with the third wave already having affected most of the world, it becomes imperative to adopt a risk-based approach toward COVID-19 patients predisposed to developing ROCM. This could be based on the most recently published literature and emerging data from centers across the world. The present review intended to elucidate the causes that brought about the current spike in ROCM and the importance of its early detection and management to reduce mortality, loss of eye, and the need for mutilating debridement.

RESUMEN

PURPOSE: To report a case of acute unilateral posterior uveitis as a rare manifestation of giant cell arteritis (GCA). OBSERVATION: A 62-year-old male presented to the clinic for evaluation of decreased vision in the right eye (OD). BCVA in OD was 20/60, and fundus examination revealed 3+ vitreous cells along with several inflammatory precipitates located in posterior vitreous and on surface of retina. Although TAB was inconclusive for GCA, the clinical diagnosis of GCA was made according to the GCA diagnostic criteria. This diagnosis was further supported by 18FDG-PET scan. The patient was started on corticosteroids, and the symptoms improved significantly after first week of treatment. At follow-up visit one month and half later, BCVA improved to 20/40 in the right eye. CONCLUSION: Although GCA is rarely present with uveitis, in case of unilateral posterior uveitis in elderly patient, it should be considered in the differential diagnosis.

RESUMEN

Intraocular tuberculosis has protean clinical manifestations and remains an important etiological differential for uveitis in an endemic region. A 27-year-old male presented with visual acuity of counting fingers close to face in right (OD) and 20/25 in left eye (OS). Examination revealed a choroidal granuloma in OS and healed serpiginous-like choroiditis in OD. Antitubercular therapy was started with systemic corticosteroids. Granuloma resolved completely; however, the patient presented with neuroretinitis and posterior scleritis, as first and second recurrence, respectively, within a oneyear period. These were managed with systemic corticosteroids and immunosuppressive therapy was added, after second recurrence. The patient responded well and maintains remission. This case presented a clinical challenge with distinct recurrence patterns of tubercular posterior uveitis in the same eye, which has not been reported before. Successful management entailed use of antitubercular therapy, corticosteroids, and immunosuppressive therapy in a step-ladder approach, resulting in preservation of vision and achieving long-term remission.

RESUMEN

A 37-year-old Indian female presented with forward protrusion of left eye for one week, associated with progressive diminution of vision. The patient had undergone sinus surgery for nasal polyposis a year ago. On examination, there was severe proptosis and limitation of extraocular movements in all gazes. CT-scan revealed a heterogeneous expansile mass, arising from left fronto-ethmoidal sinus, infiltrating left orbit. MRI showed T2-hyperintense, peripherally enhancing areas in bilateral nasal cavity (right >left), bilateral ethmoidal sinuses and frontal, sphenoidal and maxillary sinuses. Otorhinolaryngology consultation was sought and in view of vision threatening proptosis - with likely orbital compartment syndrome - emergent endoscopic guided exploration and orbital decompression was undertaken. Rapid relief of signs and symptoms was achieved, with normal vision, extraocular movements and resolution of proptosis. Cytology and microbiology ruled out infectious or malignant aetiology and helped in resolving a diagnostic dilemma. Histopathology confirmed the diagnosis of mucopyocele and follow-up period was uneventful.

RESUMEN

A 58-year-old Indian man presented with pain and redness of the left eye (OS) for one day. Patient had undergone silicone oil removal in OS for emulsified oil following vitrectomy and oil tamponade six months ago when he was diagnosed with retinal detachment in both eyes due to HIV retinopathy. Retinal detachment in the right eye (OD) was inoperable and had turned prephthisical at presentation, while his vision in OS was finger counting. Intraocular pressure in OD was 8 mm Hg and unrecordably elevated in OS. Extraocular movements were limited by periorbital oedema and proptosis. Slit-lamp examination revealed corneal haze, cells 2+/flare 1+ with pseudophakia, and attached retina. Histopathology showed lipogranulomatous inflammation, hitherto unreported in association with silicone oil. The index case posed a management challenge since his only functional eye had potentially been compromised by glaucoma and orbital cellulitis with compartment syndrome, against the backdrop of an immunocompromised status.

RESUMEN

OBJECTIVE: To evaluate ocular manifestations of reverse transcriptase (RT)-PCR-confirmed SARS-CoV-2-infected patients in a validated comparative model, and additionally to evaluate the correlation between severity of COVID-19 and ocular manifestations. METHODS AND ANALYSIS: In a prospective cross-sectional study, a total of 2400 subjects were enrolled over a period of 8 months. To eliminate bias of identical ocular symptom profile in other non-COVID-19 respiratory infections and to acquire a comparative model, 1200 COVID-19 RT-PCR-positive patients (group 1) and 1200 RT-PCR-negative patients (group 2) were included. Data collection included use of a prestructured tool and 'Google-forms', along with stratification of patients into 'mild, moderate, and severe' categories. Study subjects were evaluated for ocular manifestations by clinical examination and laboratory work-up. Univariate and multivariate logistic regression analyses were performed. RESULTS: 144 (12%) patients in group 1 had ocular symptoms as compared with 24 (2%) patients in group 2 (p<0.001). Ocular manifestations (symptoms and signs) comprising burning sensation (6.7%, p<0.001), foreign body sensation and irritation (7.0%, p<0.001), and conjunctival signs (2.7%, p<0.001) were found statistically significant in group 1 as compared with group 2. Ocular involvement increased in proportion to severity of COVID-19: mild (5.3%), moderate (24.6%) and severe (58.8%) (p=0.0006). CONCLUSION: The frequency of occurrence of ocular manifestations was higher in group 1 as opposed to group 2. Furthermore, the presence of ocular manifestations carried a direct correlation with severity of systemic disease and presence of comorbidities.

RESUMEN

Microbial keratitis is devastating corneal morbidity with a variable spectrum of clinical manifestations depending on the infective etiology. Irrespective of the varied presentation delayed treatment can lead to severe visual impairment resulting from corneal ulceration, possible perforation, and subsequent scarring. Corticosteroids with a potent anti-inflammatory activity reduce host inflammation, thus minimizing resultant scarring while improving ocular symptoms. These potential effects of corticosteroids have been applied widely to treat various corneal diseases ranging from vernal keratoconjunctivitis to dry eye disease. However, antimicrobial therapy remains the mainstay of treatment in microbial keratitis, whereas the use of adjunctive topical corticosteroid therapy remains a matter of debate. Understandably, the use of topical corticosteroids is a double-edged sword with pros and cons in the treatment of microbial keratitis. Herein we review the rationale for and against the use and safety of topical corticosteroids in the treatment of infective keratitis. Important considerations, including type, dose, efficacy, the timing of initiation of corticosteroids, use of concomitant antimicrobial agents, and duration of corticosteroid therapy while prescribing corticosteroids for microbial keratitis, have been discussed. This review intends to provide new insights into the therapeutic utility of steroids as adjunctive treatment of corneal ulcer.

RESUMEN

Vitreous biopsy is essential for establishing a definitive diagnosis and guiding potential therapy in patients with refractory vitritis and posterior uveitis, among other indications. Especially in cases where one must rule out intraocular lymphoma, obtaining a significant amount of undiluted vitreous increases diagnostic yield. We demonstrate our technique for obtaining a significant amount of undiluted vitreous using pars plana vitrectomy with air infusion.

RESUMEN

A 44-year-old Asian Indian woman presented with a history of pain and redness in the left eye for 3 weeks. Scleral congestion with a nodular swelling was present inferotemporally. Raised C reactive protein and positive antinuclear and perinuclear antineutrophil cytoplasmic antibodies suggested autoimmune scleritis. The patient was therefore managed with corticosteroids. Nevertheless, the development of severe pain associated with a scleral abscess led to a revised diagnosis of infectious scleritis. Corticosteroids therapy was halted and urgent debridement was performed. Microbiology confirmed fungal scleritis due to Coprinopsis cinerea Multiple full-thickness circumferential debridements with antifungal therapy resulted in satisfactory anatomical and visual outcomes. This case presented a unique challenge, since laboratory results were misleading, and corticosteroids resulted in a fulminant clinical course. Therefore, aggressive circumferential debridement was performed to achieve the elimination of a rare fungal aetiology of scleritis, which has not been reported previously to cause human infection.
