Characterization of retinal hemorrhages delimited by the internal limiting membrane.

Clinically, hemorrhages at the vitreoretinal interface have been termed as 'pre-retinal' in location. However, there is a careful distinction to be made between sub-hyaloid and sub-internal limiting membrane (ILM) planes of blood collection. In the past half-century, a body of literature has accrued on sub-internal limiting membrane hemorrhage.

Gene Therapy for Inherited Retinal Diseases: From Laboratory Bench to Patient Bedside and Beyond.

This comprehensive review provides a thorough examination of inherited retinal diseases (IRDs), encompassing their classification, genetic underpinnings, and the promising landscape of gene therapy trials. IRDs, a diverse group of genetic conditions causing vision loss through photoreceptor cell death, are explored through various angles, including inheritance patterns, gene involvement, and associated systemic disorders. The focal point is gene therapy, which offers hope for halting or even reversing the progression of IRDs.

Radiation chorioretinopathy: unusual occurrence of intervortex venous anastomosis.

A woman in her 60s presented with vision blur in both eyes, a year post-radiotherapy for oral cancer. The best corrected visual acuity was 20/40 in both eyes. Posterior segment examination was remarkable for a unilateral intervortex venous anastomosis in choroid in her right eye, on the side of her face that had received radiation.

Prevalence of diabetic retinopathy in urban and rural India: A systematic review and meta-analysis.

A systematic review and meta-analysis were conducted to estimate the prevalence of diabetic retinopathy (DR) in India's urban and rural areas. Medline, Scopus, and ScienceDirect databases were searched for population-based studies published in English between January 1990 and April 2021, wherein the prevalence of DR among Indian residents with type 2 diabetes mellitus (DM) was reported. A random-effects model was used to estimate the overall, rural, and urban prevalence.

Fulminant fungal endogenous endophthalmitis following SARS-CoV-2 infection: A case report.

Systemic corticosteroids and immunocompromised state following SARS-CoV-2 infection can predispose individuals to endogenous endophthalmitis. A 66-year-old gentleman presented with complaints of diminution of vision and redness one week post discharge after hospitalization for COVID-19 infection. Clinical examination suggested fulminant endogenous endophthalmitis which responded poorly even after aggressive treatment requiring evisceration.

Perceived difficulties and complications in learners of phacoemulsification: A principal component analysis model.

Purpose: To evaluate the difficulty perceived of each step of phacoemulsification and analyze the factors affecting them.

Methods: Overall, 12 trainee residents were allotted 10 cases of phacoemulsification of eyes with senile cataract, under a single observer, and the steps of each surgery were rated from very easy to very difficult with a questionnaire. The completion rates of steps and complications of each surgery were noted.

Small incision lenticule extraction (SMILE) techniques: patient selection and perspectives.

Refractive lenticule extraction is becoming the procedure of choice for the management of myopia and myopic astigmatism owing to its precision, biomechanical stability, and better ocular surface. It has similar safety, efficacy, and predictability as femtosecond laser-assisted in situ keratomileusis (FS-LASIK) and is associated with better patient satisfaction. The conventional technique of small incision lenticule extraction (SMILE) involves docking, femtosecond laser application, lenticule dissection from the surrounding stroma, and extraction.
