Acute central retinal artery occlusion with emboli.

CRAO is an ophthalmic and medical emergency. This case is a reminder that diagnosis and management of CRAO begins with ophthalmologists but immediately thereafter care involves emergency cardiovascular and neurological similar to cerebral stroke.

Frosted branch angiitis as an immune recovery response in newly diagnosed acquired immunodeficiency syndrome and systemic cytomegalovirus infection.

Frosted branch angiitis (FBA) is an uncommon form of severe retinal perivasculitis associated with systemic inflammatory/infectious diseases. In this report, we describe a case of FBA and macular edema as a result of immune recovery response in a patient newly diagnosed with HIV infection and cytomegalovirus viremia.

Real-Time (iOCT) Guided Epiretinal Membrane Surgery Using a Novel Forceps with Laser-Ablated Microstructure Tip Surface.

PURPOSE: We investigated intraoperative OCT (iOCT)-guided epiretinal membrane (ERM) and internal limiting membrane (ILM) removal using a novel forceps with a laser-ablated tip surface; it was designed to help prevent indentation force, shear stress, or tractional trauma when grasping very fine membranes. PATIENTS AND METHODS: This retrospective study included patients who underwent 23- and 25-gauge pars plana vitrectomy (PPV) for vitreoretinal interface disorders. ERM and ILM peeling was performed under guidance with microscope-integrated iOCT using novel ILM forceps with laser-ablated tip surfaces. These forceps were engineered to enhance friction when grasping tissue. Evaluation of ERM/ILM manipulation included postoperative slow-motion video analysis of the number of grasping attempts, initial ILM mobilization, and observed damage to retinal tissue. RESULTS: ERM/ILM removal was successfully performed in all patients, with an average of four grasp actions to initial membrane mobilization (91%). Additional use of a diamond-dusted membrane scraper was used in two cases (9%). Mean best-recorded visual acuity (BRVA) logMAR improved from 0.5 ± 0.34 to 0.33 ± 0.36 (p = 0.05) and mean central retinal thickness (CRT) improved from 462 ± 146 µm to 359 ± 78 µm (p = 0.002). Postoperative iOCT video analysis demonstrated hyper-reflectivity of the inner retinal layers associated with retinal hemorrhage in five eyes (22%), but no grasping-related retinal breaks. CONCLUSIONS: The texturized surface on the tips of the ILM forceps were found to be helpful for mobilizing ILM edges from the retinal surface. iOCT-guided ERM surgery also allowed for improved intraoperative tissue visualization. We believe that these two technologies helped reduce both unnecessary surgical maneuvers and retinal damage.

Combined Topical Anti-inflammatory and Oral Acetazolamide in the Treatment of Central Serous Chorioretinopathy.

SIGNIFICANCE: Central serous chorioretinopathy (CSCR) is still a therapeutic challenge with no criterion standard treatment. However, anatomic changes at the level of the retinal pigment epithelium could prove of predictive value in the course of the disease for selective treatment in cases of increased risk of chronicity. PURPOSE: This pilot study analyzes the efficacy for treating acute CSCR with combined systemic acetazolamide 250 mg twice a day and nepafenac 0.1% eye drops three times a day in comparison with an untreated control group. It also evaluates the presence a pigment epithelial detachment (PED) as a risk factor for chronic CSCR. METHODS: Nineteen consecutive patients (group 1) with new or new onset of recurrent CSCR were treated with oral acetazolamide and nepafenac eye drops for at least 2 months. A control group of 14 patients (group 2) with new or new onset of recurrent CSCR were untreated while under regular observation for 4 months. Primary end points were central macular thickness and best-corrected visual acuity after 4 months. Secondary end points were complete regression of subretinal fluid at 3 months and association of PED at baseline with recurrent or chronic CSCR imaged by optical coherence tomography. RESULTS: Group 1 showed significantly faster resolution of subretinal fluid with a mean central macular thickness at 4 months of 271 ± 85 µm compared with 322 ± 79 µm for group 2 (P < .05), but with no functional benefit with a best-corrected visual acuity at 4 months of 0.8 ± 0.2 for group 1 compared with 0.9 ± 0.1 for the control group (P < .05). Patients with a small flat PED were at a higher risk of developing chronic CSCR compared with patients with a dome-shaped or no PED (P < .05). CONCLUSIONS: Central serous chorioretinopathy remains a therapeutic challenge. This pilot study shows faster resolution of subretinal fluid with treatment but without functional benefit compared with observation. The presence of small, flat PED was associated with development of chronic CSCR.

Aqueous humor polymerase chain reaction in uveitis - utility and safety.

BACKGROUND: To study the value and safety of aqueous humor polymerase chain reaction (PCR) analysis for Herpes simplex, varicella zoster, cytomegalovirus, Epstein-Barr virus and Toxoplasma gondii in patients with uveitis. METHODS: Records of 45 consecutive patients with anterior and posterior uveitis who underwent AC paracentesis with PCR were reviewed. The main outcome measure was frequency of PCR positivity. Secondary outcomes were alteration of treatment, safety of paracentesis, and correlation of keratitic precipitates with PCR positivity, RESULTS: The overall PCR positivity was 48.9 % (22/45). Therapy was changed because of the PCR results in 14/45 patients (37.7 %). One patient experienced a paracentesis related complication (1/45, 2.2 %) without long-term sequelae. CONCLUSION: Aqueous PCR altered the diagnosis and treatment in over a third of our patients and was relatively safe. Aqueous PCR should be considered for uveitis of atypical clinical appearance, recurrent severe uveitis of uncertain etiology, and therapy refractory cases.
