Evaluation of trans-scleral diode laser using diopexy probe for subfoveal choroidal neovascular membrane in age-related macular degeneration.

J Clin Laser Med Surg. 2004 Apr;22(2):91-7. Venkatesh P, Gupta RK, Verma L, Tewari HK. SourceRajendra Prasad Centre for Ophthalmic Sciences, All India Institute of Medical Sciences, New Delhi, India. Abstract OBJECTIVE: To evaluate safety and short-term visual and fluorescein angiographic effects of trans-scleral diode laser photocoagulation in patients with subfoveal choroidal neovascularization from age-related macular degeneration (ARMD). BACKGROUND DATA: The visual outcome following treatment of subfoveal choroidal neovascularization in ARMD is still unsatisfactory. Various forms of therapy such as laser treatment, photodynamic therapy, radiation therapy, transpupillary thermotherapy, and surgical excision have been tried with variable results. MATERIALS AND METHODS: Patients with subfoveal choroidal neo-vascularization were treated with trans-scleral diode laser using the diopexy probe under indirect ophthalmoscopic visualization and followed up at 2, 6, and 12 weeks. Standardized...

Micropulse diode laser photocoagulation for central serous chorio-retinopathy.

Gupta B, Elagouz M, McHugh D, Chong V, Sivaprasad S. SourceKing's College Hospital, London, UK. Abstract PURPOSE: Central serous chorioretinopathy (CSC) is usually characterized by a localized detachment of the neurosensory retina that is self-limiting. However, some cases may persist or recur leading to degenerative changes of the retinal pigment epithelium and the neurosensory retina resulting in severe visual loss and requiring intervention. METHODS: This retrospective case series reports the long-term visual outcome of the use of micropulse laser photocoagulation for this condition with a review of literature. RESULTS: The mean follow up was 17.1 months. Four of the five patients had complete resolution of symptoms whereas one patient had recurrent CSC from a new leak that failed to resolve after repeat micropulse treatment despite improvement in symptoms. DISCUSSION: The outcomes in this case series confirm the long-term efficacy of micropulse laser in the management of CSC. I...

Safety-enhanced laser treatment effective for central serous chorioretinopathy

Subthreshold diode micropulse (SDM) laser photocoagulation was found to be effective for chronic idiopathic central serous chorioretinopathy (CSCR) with juxtafoveal point source leakage according to a new research study. CSCR is characterized by the accumulation of subretinal fluid (SRF) at the macula and is a common condition in young adults, especially in men with a so-called type A personality. Although CSCR generally is considered a self-limiting and benign condition, some patients may experience significant visual impairment caused by recurrent attacks of CSCR, persistent chronic neurosensory retinal detachment, or RPE atrophy. Most episodes of CSCR usually resolve spontaneously within 3 to 4 months. Traditional management has been observation alone. Laser photocoagulation and pharmacological agents have been attempted for treating CSCR. These treatment options serve only to shorten the duration of symptoms and have no effect on the recurrence rate or the final visual acuity. Tra...

Subthreshold Micropulse Laser Therapy for Retinal Disorders

Subthreshold Micropulse Laser Therapy for Retinal Disorders By Christine Kiire, MD; Sobha Sivaprasad, MD; and Victor Chong, MD ShareE-mailPrint Subthreshold, or tissue-sparing, laser therapy is a subject of interest to retinal specialists worldwide. Today, micropulse technology with 810 nm and 577 nm lasers is used to produce a therapeutic treatment without inducing intraretinal damage detectable on clinical examination during or after treatment. The controlled laser delivery of micropulse technology affords treatment options for diabetic macular edema(DME), proliferative diabetic retinopathy (PDR), central erous chorio retinopathy (CSR), macular edema secondary to branch retinal vein occlusion (BRVO), and even glaucoma. This review will explain micropulse technology and focus on its benefits and challenges in the treatment of retinal disorders. BACKGROUND Since its inception, retinal photocoagulation has become more refined, effective, and safe. It has become the first line of treatme...

Migraine

Classification: Migraine with aura Migraine without aura Treatment: acetaminophen or NSAID快發作時吃,確定NSAID無效改開Cafergot 2# stat, 然後1# q30min prn, max. 10#/wk. 有CAD的不要開Cafergot。不典型或難控制的就轉給neuro處理吧.. (comments from Dr. Yu)
