Retinal astrocytoma is an important ocular finding for diagnosis of tuberous sclerosis complex and is also an association of neurofibromatosis. The authors present findings of a case of acquired astrocytoma associated with myelinated retinal nerve fibers. The authors also discuss the images and possible cause-effect relationship between them. [Ophthalmic Surg Lasers Imaging Retina. 2017;48:441-442.].

Alex C Onishi, Peter L Nesper, Amani A Fawzi
A 41-year-old male with pseudoxanthoma elasticum who presented with progressive vision loss in his left periphery is discussed. Bilateral angioid streaks, optic disc drusen, choroidal neovascularization, and peau d'orange were present. Imaging of the area with peau d'orange with adaptive optics scanning laser ophthalmoscopy and en face optical coherence tomography at Bruch's membrane (BM) revealed a pattern identical to the patches of peau d'orange visible with conventional fundus imaging techniques. These results show that structural abnormalities at the level of BM, likely a result of calcification, correlate with the characteristic "orange peel" pattern known as peau d'orange...

Xi Chen, John B Miller, Dean Eliott
Serous macular detachment occurs in nearly 50% of eyes with optic disc pit. These macular detachments have been historically difficult to treat. The authors report a case of macular retinal detachment due to an occult juxtapapillary retinal break in a patient with optic disc pit refractory to prior treatments. This case demonstrates that a presumed serous detachment associated with an optic disc pit may have a rhegmatogenous etiology. [Ophthalmic Surg Lasers Imaging Retina. 2017;48:432-434.].

Dilraj S Grewal, Tayler Schwartz, Sharon Fekrat
The authors report the unique response of two patients treated for cystoid macular edema (CME) secondary to central retinal vein occlusion (CRVO) who developed sequential episodes of likely sterile inflammatory responses following separate intravitreal injections of aflibercept (Eylea; Regeneron, Tarrytown, NY) and ranibizumab (Lucentis; Genentech, South San Francisco, CA) despite multiple previous uneventful injections for CME secondary to CRVO. Following the twenty-fifth aflibercept and seventh ranibizumab injection, two patients developed an acute inflammatory response, which was treated empirically with intravitreal antibiotics and topical and oral steroids (in Case 2)...

Kareem Moussa, Theodore Leng, Julius T Oatts, Robert B Bhisitkul, David G Hwang, Jay M Stewart
Deposition of dystrophic calcifications on the posterior surface of silicone intraocular lenses (IOLs) has been reported in patients with asteroid hyalosis. Accumulation of silicone oil droplets on the posterior surface of silicone IOLs in silicone-filled eyes has also been reported. Recently, a novel technique to manually remove dystrophic calcifications using a nickel titanium loop (Finesse Flex Loop; Alcon, Fort Worth, TX) was described, obviating the need for IOL exchange. Here, the authors report their outcomes with this technique in five eyes with IOL dystrophic calcifications as well as one eye with IOL silicone oil droplet accumulation...

Sengul Ozdek, Prabu Baskaran, Levent Karabas, Pedro Pereira Neves
The authors describe a modified perfluoro-n-octane (PFO)-assisted autologous internal limiting membrane (ILM) transplantation technique for macular hole (MH) reintervention and present results from a series of 11 patients. The authors harvested a free ILM flap and transplanted it into the MH under a PFO bubble. The time at which PFO is injected, the extent of coverage of PFO, and the sequence of fluid-air exchange (FAE) are crucial to overcome previously described technical difficulties of relieving the flap from forceps, stabilizing the flap into the MH, and prevention of flap dislodgement during FAE...

Daniel Q Li, Netan Choudhry
BACKGROUND AND OBJECTIVE: To assess the utility of swept-source optical coherence tomography (SS-OCT) in visualizing macular hole (MH) closure through gas-filled eyes on postoperative day (POD) 1 using a dual scanning protocol. PATIENTS AND METHODS: We examined 30 consecutive patients with full-thickness MH who underwent standard vitrectomy with SF6 (25%) gas tamponade between July 2015 and April 2016. SS-OCT imaging was performed using horizontal raster and 16-line radial scans with manual delicate focusing to evaluate MH closure status...

Optic disc melanocytoma (ODM) is a pigmented tumor with malignant potential characterized clinically as a dark brown to black lesion with feathery margins. The authors report a case of ODM and describe the utility of optical coherence tomography angiography (OCTA) in detecting superficial tumor vascularization. This case report demonstrated the ability of OCTA to reveal the fine abnormal retinal vasculature on the surface of the lesion, a characteristic of ODM, which has been previously correlated with tumor growth...

Optic disc pit is a rare congenital anomaly of the optic nerve. Retinal detachment is a common complication with poor outcomes. Many surgical alternatives have been described for the treatment of this condition, producing variable results. Herein, the authors describe four cases of optic disc pit-associated macular detachment managed with pars plana vitrectomy, fluid-air exchange, drainage of subretinal fluid through the optic disc pit, temporal peripapillary laser, and application of Evicel fibrin sealant (human) (Ethicon, Bridgewater, NJ) over the optic disc head...

The authors report the use of an adaptive optics (AO) system in an asymptomatic patient with small choroidal melanoma. A noninvasive, novel assessment that detected potential photoreceptor abnormalities in the retina overlying the choroidal lesion and adjacent retina is presented. These findings may help current clinical evaluation to monitor structural damage to the outer retina and possibly justify earlier intervention in borderline cases. Future research is warranted to recognize full potential of this imaging modality...

Optic disc pits (ODPs) are associated with serous macular detachment (SMD), which causes visual loss in 25% to 75% patients with ODPs. There are various modalities of noninvasive and invasive treatment options; however, the best method of treatment is to seal the optic disc to prevent further egress of fluid into the subretinal space. The authors report a technique that involves sealing of ODPs with autologous free flap of the internal limiting membrane (ILM). After trans pars plana vitrectomy, the ILM was peeled and plugged into the ODP...

This report describes a case of unilateral pigmented paravenous retinochoroidal atrophy (PPRCA) in a patient with low-grade unilateral intermediate uveitis. A 31-year-old woman, previously diagnosed with intermediate uveitis in the right eye (OD) presented to the clinic. Best-corrected visual acuity was 20/20 OD. Fundus examination, fluorescein angiography, autofluorescence, and optical coherence tomography OD were in keeping with a phenotypic diagnosis of PPRCA. Electrophysiology showed severe photoreceptor dysfunction of both the rod and the cone systems OD...

The authors report a 9-year follow-up of macular complications in a 66-year-old woman affected with retinitis pigmentosa (RP) and type 2 diabetes mellitus. Rarely, clinical signs of diabetic retinopathy are presented in a patient with retinal dystrophy. This patient developed a bilateral diabetic macular edema (DME), which made its management complex due to the multiple pathogenic processes involved. Despite the chronicity of the DME, visual acuity remained stable without therapy. To the authors' knowledge, this is the first report of DME in RP with such a long follow-up...
