Summary
Vitrectomy with internal limiting membrane peeling effectively treated posterior retinoschisis in high myopia. Spectral-domain optical coherence tomography (SD-OCT) documented retinal reattachment and schisis resolution, aiding visual outcome assessment.
Area of Science:
- Ophthalmology
- Retinal Diseases
- Surgical Interventions
Background:
- Posterior retinoschisis is a retinal complication associated with high myopia.
- Visual impairment in these cases necessitates understanding underlying retinal morphology.
- Spectral-domain optical coherence tomography (SD-OCT) offers detailed cross-sectional imaging of the retina.
Purpose of the Study:
- To investigate the characteristics of posterior retinoschisis in highly myopic eyes.
- To evaluate the effects of vitrectomy with internal limiting membrane peeling on retinoschisis.
- To correlate surgical outcomes with visual results using SD-OCT.
Main Methods:
- Retrospective case series of 11 highly myopic eyes undergoing vitrectomy for retinoschisis.
- Preoperative and 6-month postoperative follow-up including visual acuity and SD-OCT.
- Internal limiting membrane peeling and gas tamponade were standard surgical procedures.
Main Results:
- Preoperatively, SD-OCT revealed retinoschisis in various retinal layers and foveal detachment in some eyes.
- Photoreceptor inner and outer segment junction defects were observed in all cases.
- Postoperatively, 10 eyes showed retinal reattachment and schisis resolution; visual acuity improved in 3 eyes.
Conclusions:
- SD-OCT is crucial for visualizing retinoschisis morphology and surgical changes.
- Vitrectomy with internal limiting membrane peeling demonstrates efficacy in treating posterior retinoschisis.
- SD-OCT findings correlate with visual outcomes, highlighting its importance in managing high myopia with vision loss.

01:27Open Angle Glaucoma: Treatment
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.

01:28Angle Closure Glaucoma: Treatment
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...

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...
