Article Synopsis
- The study investigates the use of botulinum toxin A (BTX-A) in treating acute acquired comitant esotropia (AACE) in children and young adults, particularly related to increased screen time during the COVID-19 pandemic.
- Researchers analyzed data from 27 patients who received BTX-A injections to correct misalignment of the eyes caused by excessive use of devices like laptops and smartphones, focusing on the changes in eye deviation and binocular vision post-treatment.
- Results indicated that BTX-A was effective, with significant improvements in eye alignment and visual function noted, especially when treatment was administered early after symptom onset.
Article Synopsis
- The study examines the difficulties faced in managing persistent graft rejections in a patient with Macular Corneal Dystrophy (MCD) who had Penetrating Keratoplasty (PKP) surgeries and also suffers from CREST syndrome, a form of systemic sclerosis.
- A 47-year-old female patient underwent multiple surgical procedures and treatments over 13 years, which included both surgical interventions and immunosuppressive therapy, yet faced numerous graft failures and a significant decrease in vision.
- The findings emphasize the detrimental effects of systemic autoimmune disorders on surgical outcomes, suggesting a need for careful systemic assessments and potentially stronger immunosuppressive approaches to improve graft survival in similar cases.
Article Synopsis
- Manual small incision cataract surgery (SICS) is a safe and cost-effective alternative to phacoemulsification, particularly beneficial for patients in developing countries and for complex cases in developed nations.
- The new "Tunnel stamp" device assists novice surgeons in making precise sclero corneal tunnels (SCTs) by guiding incision lengths and shapes, thereby reducing complications.
- Future plans involve designing the device in transparent flexible silicon and in various sizes to cater to different cataract types, improving alignment and overall surgical outcomes.
Article Synopsis
- * Most patients (81.8%) received medical management, with 66.7% being both smear and culture-negative, while 33.3% were only smear-positive, highlighting a correlation between smear positivity and a history of injury.
- * The findings suggest that a high level of clinical suspicion, recognizing causative organisms, and starting empirical therapy with broad-spectrum antibiotics and antifungals can significantly improve patient outcomes, despite varying treatment protocols across different locations and practitioners.
Introduction: Exotropia-hypotropia complex is an uncommon phenomenon associated with high myopia. However, some literature reports cases of the exotropia-hypotropia complex where residual hypotropia is managed through a secondary surgery following the conventional recession-resection of the lateral rectus (LR) and medial rectus (MR). Nasal Loop myopexy as a primary surgical procedure for the management of exotropia-hypotropia complex has been rarely reported in the literature.

Methods: A 15-year-old male studying at school presented with defective vision in both eyes recently. He was diagnosed with progressive keratoconus in the right eye more than left eye.
Purpose: To assess the clinical outcomes of symblepharon release in patients with ocular surface chemical injury using Gore-Tex as a novel treatment option.
Methods: This was a retrospective analysis of 23 eyes of 22 chemical injury patients done during a period of January 2014 to December 2021 at a tertiary eye care centre in South India. All patients underwent symblepharon lysis along with Gore-Tex application over the sclera with minimum 1 year follow up.
Viral keratitis is a significant cause of ocular morbidity and visual impairment worldwide. In recent years, there has been a growing understanding of the pathogenesis, clinical manifestations, and diagnostic modalities for viral keratitis. The most common viral pathogens associated with this condition are adenovirus, herpes simplex (HSV), and varicella-zoster virus (VZV).

Methods: A 55-year-old male farmer presented with a history of pain, redness, and defective vision. The corneal scrapings revealed septate hyphae macroconidia and multi-celled chlamydospores with lactophenol cotton blue mount.
Purpose: To analyze the reasons for declining corneal refractive laser correction procedures in patients presenting to tertiary eye care centers in Tamil Nadu, Southern India, and review the literature.
Methods: Retrospective case records of subjects presenting from January 2019 to December 2021 for refractive surgery workup were analyzed. Demographic details and refractive parameters of patients rejected for corneal refractive laser corrections (CRLC) were documented and reviewed.
Epithelial ingrowth under LASIK flaps: tips and tricks for preventing recurrence!
Indian J Ophthalmol
September 2023
Background: LASIK for refractive error correction has become a universal surgery. Despite its popularity, the estimated prevalence of traumatic flap dislocations in post-LASIK patients is 3.9%, and it is sometimes associated with epithelial ingrowth.

Methods: A total of 41 patients, presenting to cornea clinic were included in the study and divided into five groups depending on the type of diagnosis: Group 1, with either >2 weeks of Persistent epithelial defect following cataract/retinal/glaucoma surgeries or Shield ulcers, Group 2 with >4 weeks of Non healing corneal ulcers, Group 3 with chemical injuries, Group 4 with Epithelial defects following keratoplasty, and Group 5 is the miscellaneous group.
Results: The mean age of the study subjects was 50.
Corneal blindness (CB) is one of the leading causes of blindness in India and globally, affecting around 8 million population worldwide. Many of these corneal blind patients may be visually rehabilitated by corneal transplantation (CT). Eye banking plays a crucial role in facilitating CT and ocular research.

- * The patient, who had pseudophakic bullous keratopathy, experienced unexpected vision loss after four months of BCL treatment meant to alleviate pain.
- * Investigations, including a slit-lamp examination and microbial testing of the removed BCL, confirmed the presence of the fungus using Sanger sequencing for precise identification.
Small traumatic iridodialysis (ID) may be asymptomatic, but large ones usually cause polycoria and corectopia, leading to symptoms like diplopia, glare, and photophobia. The management of ID, including medical and surgical methods, depends upon the patient's symptoms. Mild glare and diplopia can be treated either with atropine, antiglaucoma medications, tinted spectacles, colored contact lens, or corneal tattooing, but extensive IDs require surgical options.
View Article and Find Full Text PDFPurpose: To find out parents' knowledge, attitude, and treatment practice (KAP) toward pediatric eye problems and to assess the effect of demographic factors such as gender, age, educational status, and number of children on KAP.
Methods: A cross-sectional descriptive study was conducted in a hospital setting. Two hundred parents were randomly selected for the questionnaire.
Management of pediatric subluxated cataract and different methods to face the challenges.
Indian J Ophthalmol
February 2023
Background: Traumatic cataracts present in multiple and different forms. Based on the nature of injury, it necessitates a customized approach for individual case. Capsulorhexis and in the bag intraocular lens (IOL) placement are vital for long term centration of pediatric IOLs.
