Purpose.Retinal redetachment of silicone oil-filled eyes continues to be a frustrating condition that typically requires retinectomy. We proposed radial retinotomy as a potentially less invasive surgery. Here, we preliminarily explored its feasibility, efficacy, and safety.Methods.Totally 9 eyes of 9 consecutive patients were included in a prospective noncomparative trial. A series of retinotomies were created by endodiathermy in a radial pattern to relax the foreshortened retina. The eye was refilled with fresh silicone oil. The treated eyes were examined via visual acuity (VA) tests, tonometry, slit-lamp microscopy, and fundus photography during a 6-month observation period.Results.The procedure was completed in an average of 28 minutes from silicone oil removal to fresh silicone oil placement. Fundus photography demonstrated that 7 of the 9 eyes (78%) exhibited retinal reattachment. On average, VA was significantly improved within the first 2 weeks (P=0.02) and remained stable for the following 6 months. The change in intraocular pressure was not significant (P=0.76), and no adverse event was observed (0%).Conclusion.Radial retinotomies with endodiathermy were shown to be feasible, effective, and safe in selected cases of inferior contracted retina without vitreous base fibrosis over a 6-month observation period. This trial is registered withNCT02201706.

The eyes of 7 rabbits with clinical megaloglobus, selected from a large colony, were studied with slit-lamp microscopy, gonioscopy, indirect ophthalmoscopy and tonometry. Selected light and scanning electron microscopy was also performed. There were 11 glaucomatous eyes among the 7 rabbits: gonioscopy demonstrated open iridocorneal angles with absence of pectinate fibres. Incomplete cleavage of the iridocorneal angles in glaucomatous eyes was noted histologically. Because of the similarity of the iridocorneal angles of glaucomatous rabbit eyes with those of human eyes with congenital glaucoma, these rabbits may serve as an experimental model in the understanding and management of certain types of human glaucoma.

This article describes the real time instrumentation system to help blindness people for recognize a colour. Colour image captured by the digital camera, and it classified into ten basic colours names (black, brown, cyan, red, orange, yellow, green, blue, magenta, gray and white) by using entropy algorithm. The conclusion of colour classification will be informed to the user in sound or vocal information. This study has used two colour models HSV (hue, saturation and value) and RGB (red, green and blue). The accuracy of Classification using HSV has 90%, and RGB model has 71.5%.
