Summary
High air infusion during vitrectomy can cause retinal damage, leading to breaks, detachment, or visual field defects. Surgeons should be cautious of infusion flow rates to prevent iatrogenic injury.
Area of Science:
- Ophthalmology
- Surgical Techniques
- Retinal Surgery
Background:
- Pars plana vitrectomy is a common surgical procedure for various retinal conditions.
- Air-fluid exchange is frequently used during vitrectomy to maintain intraocular tamponade and visualize the retina.
Observation:
- Two cases of retinal damage following pars plana vitrectomy with air infusion are presented.
- Damage occurred in the retina contralateral to the air infusion port due to high infusion flow.
Findings:
- Case 1: Retinal whitening progressed to a retinal break and detachment.
- Case 2: Retinal whitening resolved but resulted in an inferotemporal visual field defect.
Implications:
- High intraocular pressure from rapid air infusion can cause significant retinal trauma.
- This pressure-induced injury may manifest as retinal whitening, breaks, detachment, or visual field deficits.
- Careful control of infusion flow rates is crucial during vitrectomy to prevent iatrogenic retinal damage.

DefinitionDiabetic retinopathy is a microvascular complication of diabetes affecting the retinal blood vessels.Risk FactorsDiabetic retinopathy is present in almost all individuals with type 1 diabetes and more than 60% of those with type 2 diabetes after two decades of disease.The risk increases with poor glycemic control, hypertension, dyslipidemia, smoking, pregnancy, and puberty.Although cataracts and glaucoma are also more frequent in people with diabetes, retinopathy remains the leading...
01:25Glaucoma: Overview
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...
01:22Photoreceptors and Visual Pathways
At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category, whereas...
