Evaluation of macular choroidal and microvascular network changes by activity scores and serum antibodies in thyroid eye patients and healthy subjects.

Aim: To investigate the choroidal thickness and the microvascular network changes around the macula in thyroid eye disease (TED) patients at different stages and the relationship of those changes with risk factors, serum antibodies and the severity of TED.

Methods: A total of 85 participants were enrolled. All participants underwent ophthalmology and endocrinology examinations.

Imaging of the lower punctum with anterior segment OCT in patients with dacryocystorhinostomy who underwent bicanalicular silicone tube implantation.

Unlabelled: Spectral domain OCT imaging of the lower punctum in cases with silicone tube implantation OBJECTIVE: To record the structural changes in the lower punctum by performing spectral domain anterior segment OCT imaging of dacryocystorhinostomy cases who underwent bicanalicular silicone tube implantation.

Methods: Thirty eyes of 30 patients who underwent bicanalicular Crawford silicone tube implantation with dacryocystorhinostomy were included in the study. The mean age of the cases was 53 ± 13.

Changes in retinal vessel and retinal layer thickness after cross-linking in keratoconus via swept-source OCT angiography.

Purpose: To analyze the postoperative foveal avascular zone (FAZ) area, superficial capillary plexus (SCP), deep capillary plexus (DCP) vascular densities (VD), and retinal layers after cross-linking (CXL) for keratoconus treatment.

Methods: Twenty-seven eyes with cross-linking treatment for keratoconus were included in the study. Foveal avascular zone (FAZ) area, SCP VD, DCP VD, and retinal layers were evaluated by using optical coherence tomography angiography (OCTA).

Anterior segment optical coherence tomography findings in leukemic iris infiltration.

Iris involvement by acute lymphoblastic leukemia is a very rare primary leukemic infiltration. Blurred vision, conjunctival injection, anterior chamber reaction, pseudohypopyon, thickening of the iris stroma, change in iris shape and color are common clinical signs in leukemic iris infiltration. There is no optimal treatment.
