چکیده
Patient: A 43 year old female patient lpresented herself pointing up a capillary haemangiama of the retina in the area of the upper VaSCUlar arge wlth a semus detachment of the sensory retina as well as an intraretinal semus maculopathy of the left eye. The visual acuity of the left eye was reduced to 0.5. that 01 lhe right eye was 1.0. The oohthalmolooical findinos were normal. ‘The familv’s medical histow did nbt point to any other fimilial members being affected. AngiomatoSis in other organs (liver, pancreas, kidney, adrenal body, CNS. paranasual sinuses) were not evident. Following weparalory cryocoagulation, we performed a direct lasercoagulation of tile angioma by means of argon and krypton laser under local and at firs1 systemic steroid therapy within several sessions. Prior and to end after the respective laser treatments. we carried out the tyndallomeby by means of the LFCM (FC-1000 Kowa). The follow up was 8 months. Results: 1. The flare values [photon countslms] of the affected eye increased at the beginning of therapy (10.4. normal value < 8). 2. In the course of the lasertherapy the flare valu?s increased up to 22.5. 3. The flare values. which had returned to normal upon termination of the lasertherapy. rose again briefly following spontaneous repelfusion (to 23.6) before normalizing upon renewed lasertherapy resulting in the closihg of the capillary haemangioma (4. 7) 4 The visual acuity fmally W1F 1 0 __ _ Conclusion: The disorder of the blood-eye-bamer may corelate with the Derfusion dearee of a retinal caoillarv hemanaioma. Thus the LFCM permits an n& Invasive quanlifyin’g statement orthe course and Success of a lasertherapy of a retinal capillary haemangloma.

Retinopathy of Prematurity Transscleral Retinal Photocoagulation (TSRPC) The 810 nm diode laser wavelength makes lens-sparing transscleral coagulation of the retina possible, and to evaluate the efficacy and safety of transscleral diode laser coagulation for threshold ROP, the authors performed a controlled clinical study. Forty eyes of 20 preterm infants (gestational age 24-29 weeks, mean 26.8...

BACKGROUND Transscleral retinal photocoagulation with a diode laser is used in glaucoma refractory to medical and surgical treatment. Our main research question was how the technique performed in large vascular lesions associated with hemangiomas of the retina and choroid. METHODOLOGY/CLINICAL FINDINGS Patient charts were retrieved from the hospital files for patients who underwent the proced...
متن کاملHistopathologic and ultrastructural findings of photocoagulation lesions produced by transpupillary diode laser in the rabbit retina.
Transpupillary retinal photocoagulations were performed on ten eyes of five pigmented rabbits using a diode laser (Nidek Co., LTD, Aichi, Japan) emitting infrared radiation at 800 nm wavelength. A histological and an ultrastructural study on the treated eyes were done at 1, 3, 5, and 7 days after retinal photocoagulations. The purpose of this study was to observe the sequential changes in the r...

The binocular indirect argon laser photocoagulator was newly designed to enable visualisation of the entire fundus during panretinal laser photocoagulation and to treat retinal tears immediately after buckling procedures of the sclera. The lamp housing of the binocular ophthalmoscope was remodelled and adjusted so that the laser beam and illuminating light are coaxial after leaving the ophthalm...
