PURPOSE: To describe an unusual case of unilateral, chronic symptoms and signs of dry eye, and recurrent episodes of ocular irritation related to pinguecula, which were refractory to prior medical treatments, successfully treated with argon laser photocoagulation. METHODS: A 36-year-old man presented with an elevated yellowish mass on his conjunctiva in his left eye, which was associated with dry eye symptoms and general discomfort, such as "tightening sensation" and "stiffness"...

We compared the effect of panretinal photocoagulation (PRP) using short-pulse laser (SPL) and conventional laser, regardless of the number of spots, in terms of their effect on the progression of diabetic macular edema (DME) and anterior flare intensity (AFI) in patients with high-risk nonproliferative diabetic retinopathy (non-PDR). Forty-two eyes of 42 patients were subjected to PRP using the conventional argon laser (Conv group) or SPL (SPL group). CRT and AFI levels in the SPL group were significantly lower than those in the Conv group (CRT at 4, 6, and 10 weeks; AFI at 6, 10, and 18 weeks)...

Presently described is case of a 42-year-old woman with eye injury that was result of gunshot fired by a man at a wedding celebration. Bullet penetrated inferior quadrant of nasal sclera of left eye 7-12 mm behind limbus. Choroid and vitreous were prolapsed around bullet. Hemorrhage, vitreous prolapse and lens subluxation were present in anterior chamber. Presenting visual acuity (VA) was hand motion. Bullet 14x5 mm in size was carefully extracted from the eye. Fifteen days later, argon laser photocoagulation was performed on retina in area of bullet entry point...

REVIEW
Nidhi Relhan, Harry W Flynn
PURPOSE OF REVIEW: To provide an historical review of the Early Treatment Diabetic Retinopathy Study (ETDRS) in the management of diabetic macular edema (DME), and to discuss its relevance to the management of DME. RECENT FINDINGS: The ETDRS reported that argon laser treatment is beneficial in the management of 'clinically significant' DME. The study provided guidelines for the treatment with focal and/or grid laser based on fluorescein angiographic patterns. In today's world, with the advent of optical coherence tomography, 'clinically significant' DME is now classified into center-involved DME (CI DME) and noncenter-involved DME (non-CI DME)...

CLINICAL CASE: A 14 year-old boy with Coats' disease in his right eye, presented with a visual acuity (VA) of 0.1, micro-aneurysms, exudates, a macular oedema of 959 microns, and peripheral telangiectasias. After 12 months follow-up with 6 ranibizumab injections and 3 sessions of argon laser photocoagulation, the macular oedema remained and VA was 0.2. Following 4 aflibercept injections and another 2 laser sessions, he had a good foveal slope and a VA of 0.5, with no recurrences in the last 12 months...

We report a case of a choroidal neovascular membrane (CNVM) associated with sclerochoroidal calcification (SCC). An asymptomatic, 72-year-old male was referred to our institution for yellow-white placoid retinal lesions of both eyes. B-scan ultrasonography confirmed the diagnosis of SCC, and indocyanine green angiography confirmed the presence of an associated CNVM. Due to enlargement of a hemorrhagic pigment epithelial detachment associated with the CNVM over the course of 7 months, the patient was treated with a series of bevacizumab injections followed by photodynamic therapy (PDT)...

AIM: To evaluate the efficacy of combination therapy of argon laser photocoagulation and intravitreal antivascular endothelial growth factor (VEGF) injection in idiopathic polypoidal choroidal vasculopathy (PCV) involving macula. MATERIALS AND METHODS: A retrospective interventional study involving 12 eyes of 11 patients diagnosed with PCV involving the macula on indocyanine green angiography (ICGA). Intravitreal anti-VEGF was given in eyes with significant subretinal/sub retinal pigment epithelium hemorrhage or exudation...

Ophthalmomyiasis interna posterior is a rare condition caused by the invasion of the ocular posterior segment by the larval form of certain flies in the order Diptera. The main clinical features are reduced visual acuity, intense posterior uveitis, and neuroretinitis. Treatment of this condition is predominantly surgical, including argon laser photocoagulation for subretinal larva and pars plana vitrectomy for intravitreal infection. We report a case of ophthalmomyiasis interna posterior in a 12-year-old girl that masqueraded as orbital cellulitis and was successfully treated with Nd:YAG laser photodisruption...

OBJECTIVES: To describe the first case of Descemet membrane endothelial keratoplasty (DMEK) combined with argon laser photocoagulation and intracameral 5-fluorouracil (5-FU) injection in a patient with epithelial downgrowth after cataract surgery. METHODS: Case report and review of the literature. RESULTS: A 77-year-old female underwent uneventful cataract surgery using a clear corneal incision in her left eye. Six months after surgery, an epithelial cell sheet began to cover the posterior cornea and then spread to the anterior chamber structures, leading to anterior synechia and corectopia at 2 years...

In today's modern pharmacologic approach to treating sight-threatening retinal vascular disorders, there is an increasing demand for a compact, mobile, lightweight and cost-effective fluorescein fundus camera to document the effects of antiangiogenic drugs on laser-induced choroidal neovascularization (CNV) in mice and other experimental animals. We have adapted the use of the Kowa Genesis Df Camera to perform Fundus Fluorescein Angiography (FFA) in mice. The 1 kg, 28 cm high camera has built-in barrier and exciter filters to allow digital FFA recording to a Compact Flash memory card...

PURPOSE: Symptomatic retinal arterial macroaneurysms (RAM) are primarily investigated by fundus fluorescein angiography after presenting with visual disturbance. The natural history includes spontaneous regression and occasionally occlusion of the arteriole distal to the aneurysm. RAM may be managed conservatively. Interventional treatment options include focal argon laser photocoagulation, Nd:YAG laser hyaloidotomy, and pars plana vitrectomy. The purpose of this study was to elicit the rates of distal vessel occlusion and aneurysm thrombosis in RAM at presentation, and their relevance to the treatment of RAM...

REVIEW
P Niederer, F Fankhauser
Photothermal treatment of tumors of the retina and choroid such as retinoblastomas, malignant melanomas, benign tumors as well as of vascular malformations can be performed by using laser radiation. A number of basic physical laws have to be taken into account in this procedure. Of particular importance thereby are: Arrhenius' law to approximate the kinetics of protein denaturation and photocoagulation, furthermore the electromagnetic radiation field, the distribution of both radiant and thermal energy induced in tumors and vascular structures, the influence of the wavelength and laser pulse duration (exposure time), as well as of the optical properties of the tissue...

AIM: To compare argon laser photocoagulation and intrastromal injection of voriconazole as adjunctive treatment modalities in cases of resistant mycotic corneal ulcers. METHODS: Two groups each of them included 20 cases of resistant mycotic corneal ulcers. Both groups treated with local and systemic specific antimicrobial drugs guided with culture and sensitivity results. In one group argon laser photocoagulation was used as an adjunctive therapy to the specific antifungal drugs and in the other group, intrastromal injection of voriconazole was done besides the specific antifungal drugs...
