Injection pressure levels for creating blebs during subretinal gene therapy.

Retinal damage has been associated with increased injection pressure during subretinal gene therapy delivery in various animal models, yet there are no human clinical data regarding the pressures required to initiate and propagate subretinal blebs. This study characterized the intraoperative pressure levels for subretinal gene therapy delivery across eight retinal conditions. A total of 116 patients with retinal degenerative diseases have been treated with subretinal gene therapy at OHSU-Casey Eye Institute as of June 2020; seventy patients (60.

Intraoperative optical coherence tomographic findings in patients undergoing subretinal gene therapy surgery.

Background: To analyze intraoperative OCT (iOCT) findings during subretinal gene therapy.

Methods: A single-center, retrospective, observational, case series study of twenty one eyes submitted to subretinal gene therapy. Intrasurgical high definition videos were included for analyzes.

Multimodal imaging of ring 14 syndrome associated maculopathy.

: Ring 14 syndrome is a rare chromosomal disorder characterized by a ring-shaped appearance of chromosome 14. Classically findings include distinct facial characteristics, refractory epilepsy, global development delay, muscular hypotonia and ocular abnormalities. Here we report a retinal multimodal imaging analyses of a ring chromosome 14 syndrome patient with associated macular pigmentary changes.

Manifestation of a solitary retinal astrocytic hamartoma in a patient with Best macular dystrophy.

Purpose: To report the case of an adolescent male with a history of Best macular dystrophy and retinal astrocytic hamartoma.

Observations: A 15 year old male with a history of Best macular dystrophy who had been followed by ophthalmology for 9 years was noted to have progressive enlargement of a superonasal peripapillary retinal lesion. Imaging and exam are consistent with a diagnosis of retinal astrocytic hamartoma.

[An advanced case of basosquamous carcinoma of the orbit: case report].

Basosquamous carcinoma is a rare tumor with features of both basal cell and squamous cell carcinoma, linked by a transition area. It is a rare epithelial neoplasm with a tendency for local recurrence. It also has a high incidence of distant metastasis, a condition that differentiates it from the basal cell carcinoma.
