Prevention and management of childhood progressive myopia: National consensus guidelines.

Myopia is a major public health problem worldwide, including India, with the global prevalence of myopia increasing rapidly over decades. The clinical and socioeconomic impact of myopia is also expected to rise with rising prevalence. Therefore, the focus has now been shifted to prevent the incidence and progression of myopia. However, there is lack of any standardized guidelines for myopia management. This document aims to generate a national-level expert consensus statement on the management of childhood myopia in the Indian scenario. The expert panel of pediatric ophthalmologists consisted of 63 members who met in a hybrid meeting. A list of topics deliberating discussion in the meeting was provided to the experts in advance and they were instructed to provide their opinions on the matter during the meet. The panel of experts then gave their views on each of the items presented, deliberated on different aspects of childhood myopia, and reached a consensus regarding the practice patterns in the Indian scenario. In case of opposing views or lack of a clear consensus, we undertook further discussion and evaluated literature to help arrive at a consensus. A written document is prepared based on recommendations explaining definition of myopia, refraction techniques, components and methods of workup, initiation of anti-myopia treatment, type and timing of interventions, follow-up schedule, and indications for revised or combination treatment. This article formulates evidence-based guidelines for progressing myopes and pre-myopes and also establishes uniformity in the management of childhood myopia in the country.

A rare case of cortical blindness following vaccination against SARS-CoV-2.

A 61-year-old male presented with sudden loss of vision in both the eyes about 8 days after the first shot of coronavirus disease 2019 (COVID-19) vaccine (Covishield). On examination, the visual acuity was no perception of light in both the eyes. Contrast-enhanced magnetic resonance imaging (MRI) with diffusion-weighted imaging showed acute cerebral infarcts involving bilateral parieto-occipital region. Considering the temporal correlation with the vaccine shot and absence of any other precipitating factor, we hypothesized that this was probably an immunologic response to the vaccine.

A case of neuro retinitis in association with COVID-19.

A 36-year-old female presented with blurring of vision in one eye for 10 days after 1 month of an episode of COVID-19 infection. Her fundus showed disc edema with blurring of margins along with exudation around the fovea. Her C-reactive protein levels were raised. She responded well to oral steroids. A likely association with COVID-19 infection and its associated immune response was suspected.

Multimodal ocular imaging in diagnosis and management of occupational ocular argyrosis.

Occupational ocular argyrosis is a rare disorder associated with accumulation of silver in the eye due to its occupational exposure. A 39-year-old male patient, a silver utensils polisher for the past 30 years, presented with bilateral gradual diminution of vision (presently 20/200) for 2 years. His serum silver levels were raised and ocular examination revealed bilateral greenish brown corneal deposits and complicated cataract. Anterior segment optical coherence tomography (OCT) and confocal microscopy suggested deposition of silver in various corneal layers. Multifocal electroretinogram showed a generalized decrease in sensitivity of P1 waves. Increased internal aberrations on aberrometric profile favoured phacoemulsification followed by intraocular lens implantation in both eyes. Postoperatively, the visual gain of 20/20 and normal fundus picture on indirect ophthalmoscopy, macular OCT, and fundus autofluorescence favored good prognosis in both eyes.

Clinical Role of Swept Source Anterior Segment Optical Coherence Tomography in Strabismus Re-Operation with Lost Surgical Details.

BACKGROUND: To characterize the diagnostic role of swept source anterior segment optical coherence tomography (SS-ASOCT) in strabismus re-operations with lost surgical details. METHODS: Patients presenting to our outpatient services for strabismus care from February 2020 to March 15th 2021 were systematically evaluated. Those willing to undergo re-operation were included in the study. A total of 30 patients were identified and out of this a total of 10 eyes of 10 patients with lost surgical details were finally included in the study. Demographic details, preoperative deviation, ocular findings, orthoptic measurements, detailed SS-ASOCT findings, intraoperative measurements, and post-operative outcomes were recorded. RESULTS: The mean age of 10 patients was 23.7±5.75 years. Seven were male and three were female. The mean pre-operative SS-ASOCT measured distance from angle to insertion was 8.90±1.85 mm and the mean intraoperative distance was 9.12±2.14 mm. A mean difference of 0.21±1.31 mm was noted, and this difference was statistically insignificant (paired t test, p = 0.57). In addition, SS-ASOCT unraveled novel signs to differentiate operated eyes from the un-operated eyes, and recessed muscle from the resected muscle. CONCLUSION: In strabismus re-operation with lost surgical details, the pre-operative SS-ASOCT can provide reliable muscle details with respect to its type of surgery and amount surgery.

Fulminant Sphingomonas paucimobilis keratitis: case study and review of literature.

Sphingomonas paucimobilis is a low-virulence gram-negative bacillus known to cause various ocular infections such as endophthalmitis, panophthalmitis and keratitis that are usually associated with an underlying risk factor such as peri-partum or postpartum phase, cataract surgery, contact lens use, neurotrophic keratopathy or ocular trauma. We report a case of spontaneously occurring perforated corneal ulcer caused by the organism in a young man managed by penetrating keratoplasty. The course was followed by endophthalmitis with graft infection culminating in phthisis bulbi despite aggressive medical and surgical management. Along with reporting this case, we also present a review of literature on ocular infections caused by the same organism.

Kodameae ohmeri - An Emerging Yeast: Two Cases and Literature Review.

Kodameae ohmeri is an emerging pathogen in various types of infections. Most infections are seen in patients with compromised immunity like cancer patients. Few cases of neonatal infections due to K. ohmeri have been reported earlier in premature neonates with fatal outcomes. We report two cases of fungemia; the first case was a patient with hematological malignancy, who complained of fever spikes and grew K. ohmeri in blood despite prophylactic voriconazole therapy. The second case was in a mature neonate, who developed respiratory distress and features of sepsis two days after birth, multiple blood cultures were positive for K. ohmeri. Both the patients responded well to Amphotericin B. Repeat blood cultures were sterile and patients were discharged. K. ohmeri is an unusual and emerging fungal pathogen of late an increasing number of cases of fungemia, funguria, endocarditis, peritonitis and wound infections due to the same are being reported. Some occur in immunocompromised patients and some inapparently immunocompetent patients, neonates with an inclination for preterm babies. We report two case of fungemia, one with lymphoma and the second in a neonate.
