3. Comparison of Optical Coherence Tomography Angiography to Indocyanine Green Angiography and Slit Lamp Photography for Corneal Vascularization in an Animal Model (PubMed)

Comparison of Optical Coherence Tomography Angiography to Indocyanine Green Angiography and Slit Lamp Photography for Corneal Vascularization in an Animal Model Corneal neovascularization (CoNV) could be treated by novel anti-angiogenic therapies, though reliable and objective imaging tools to evaluate corneal vasculature and treatment efficacy is still lacking. Optical coherence tomography angiography (OCTA) -currently designed as a retinal vascular imaging system- has been recently adapted (...) for anterior-segment and showed good potential for successful imaging of CoNV. However, further development requires an animal model where parameters can be studied more carefully with histological comparison. Our study evaluated the OCTA in suture-induced CoNV in a rabbit model compared to indocyanine green angiography (ICGA) and slit-lamp photography (SLP). Overall vessel density measurements from OCTA showed good correlation with ICGA (0.957) and SLP (0.992). Vessels density by OCTA was higher than ICGA

4. Slit-Lamp Needling of the Anterior Capsule for Aqeuous Misdirection Post Hyaloido-zonulectomy, and Iridectomy. (PubMed)

Slit-Lamp Needling of the Anterior Capsule for Aqeuous Misdirection Post Hyaloido-zonulectomy, and Iridectomy. We present a case of persistent aqueous misdirection, after Ahmed glaucoma valve surgery, despite undergoing an anterior vitrectomy with hyaloido-zonulectomy and iridectomy.A 73-year-old female patient, 4 months after phacotrabeculectomy, was referred with persistent high intraocular pressure (IOP). Postoperatively, she developed aqueous misdirection with a flat anterior chamber (AC (...) reformation with viscoelastic, the AC failed to deepen. An anterior vitrectomy with hyaloido-zonulectomy was performed. Initially, the AC was deep, but, a few days later, it was flat. Multiple reformations and vitreous tap failed to keep the AC deep. A 30-G needle was passed at the slit lamp across the temporal cornea, iris, and anterior capsule into the anterior vitreous cavity. The needle was then partially withdrawn and used to create a space between the intraocular lens and anterior capsule

14. Retinal slit lamp video mosaicking (PubMed)

Retinal slit lamp video mosaicking To this day, the slit lamp remains the first tool used by an ophthalmologist to examine patient eyes. Imaging of the retina poses, however, a variety of problems, namely a shallow depth of focus, reflections from the optical system, a small field of view and non-uniform illumination. For ophthalmologists, the use of slit lamp images for documentation and analysis purposes, however, remains extremely challenging due to large image artifacts. For this reason, we (...) propose an automatic retinal slit lamp video mosaicking, which enlarges the field of view and reduces amount of noise and reflections, thus enhancing image quality.Our method is composed of three parts: (i) viable content segmentation, (ii) global registration and (iii) image blending. Frame content is segmented using gradient boosting with custom pixel-wise features. Speeded-up robust features are used for finding pair-wise translations between frames with robust random sample consensus estimation

19. The fundus slit lamp (PubMed)

The fundus slit lamp Fundus biomicroscopy with the slit lamp as it is practiced widely nowadays was not established until the 1980-es with the introduction of the Volk lenses +90 and +60D. Thereafter little progress has been made in retinal imaging with the slit lamp. It is the aim of this paper to fully exploit the potential of a video slit lamp for fundus documentation by using easily accessible additions. Suitable still images are easily retrieved from videorecordings of slit lamp (...) examinations. The effects of changements in the slit lamp itself (slit beam and apertures) and its examination equipment (converging lenses from +40 to +90D) on quality and spectrum of fundus images are demonstrated. Imaging software is applied for reconstruction of larger fundus areas in a mosaic pattern (Hugin®) and to perform the flicker test in order to visualize changes in the same fundus area at different points of time (Power Point®). The three lenses +90/+60/+40D are a good choice for imaging
