Summary
Optical coherence tomography-angiography (OCT-A) revealed capillary changes in optic disc pit (ODP) maculopathy after surgery. OCT-A monitoring shows fluid reabsorption and visual recovery following inverted ILM flap surgery.
Area of Science:
- Ophthalmology
- Retinal Imaging
- Surgical Outcomes
Background:
- Optic disc pit (ODP) can lead to macular detachment, requiring surgical intervention.
- Pars plana vitrectomy with an inverted internal limiting membrane (ILM) flap is a surgical approach for ODP-associated maculopathy.
Observation:
- A 12-year-old patient with ODP-maculopathy underwent vitrectomy with an inverted ILM flap.
- Postoperative OCT-angiography (OCT-A) demonstrated capillary dropout in superficial and deep plexuses, altered choroidal vasculature, and star folds.
Findings:
- OCT-A revealed significant capillary dropout and vascular alterations in the macula post-surgery.
- Long-term OCT-A follow-up (24 months) showed normalization of macular perfusion.
- These vascular changes correlated with a complete recovery of visual acuity.
Implications:
- OCT-A is a valuable tool for monitoring subretinal fluid reabsorption after ILM flap surgery in ODP.
- OCT-A findings correlate with functional recovery, aiding in the management of rare ODP-maculopathy.
- This imaging modality can guide therapeutic strategies and assess treatment response in ODP cases.

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...
01:27Open 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...
