Two cases of telangiectatic hamartoma of the iris and ciliary body are reported, one of them with its histopathological study. No previous cases have been found, as such, in the current literature. The most important descriptions of primary vascular lesions of the iris and ciliary body are briefly reviewed.

Adeno-associated virus (AAV)-based vectors are the most frequently used platform for retinal gene therapy. Initially explored for the treatment of loss-of-function mutations underpinning many inherited retinal diseases, AAV-based ocular gene therapies are increasingly used to transduce endogenous cells to produce therapeutic proteins, thus producing site-specific biofactories. Relatively invasive ocular routes of administration (ROA) mean prominent procedure-related in-life, and histopathological findings may be observed with some regularity.

Purpose: To investigate the effect of tamsulosin on iris morphology, ciliary muscle thickness (CMT), pupil diameter (PD), and pupil responses to light using anterior segment optical coherence tomography and corneal topography.
Design: Prospective clinical before-and-after study METHODS: The right eyes of 43 patients with newly diagnosed benign prostatic hyperplasia were included in this study. Iris dilator muscle region (DMR) thickness, sphincter muscle region (SMR) thickness, DMR/SMR ratio, PD (scotopic, mesopic and photopic light conditions), CMT1(1 mm posterior to the scleral spur), CMT2(2 mm posterior to the scleral spur), CMT3(3 mm posterior to the scleral spur) and anterior chamber depth(ACD) were measured before and after dilation.

Background: Anterior segment ischaemia (ASI) is a rare but feared complication associated with strabismus surgery, arising from damage of the anterior ciliary arteries that run along the extraocular rectus muscles. It has been reported that the risk of ASI following strabismus surgery increases when the vertical rectus muscles are involved. The aim of the present study was to monitor anterior segment perfusion in real time during inferior rectus muscle surgery.

Despite the wide range of surgical indications, IOL dislocation and aphakia following complicated cataract surgery or other complicated intraocular procedures and trauma remain the most common reasons for secondary IOL implantation. In cases where it is not feasible to place the artificial lens in the capsular bag due to zonular weakness or insufficient stability of the capsular bag, the intraocular lens can be implanted in the anterior chamber or fixed in the ciliary sulcus, on the iris or on the sclera.
