Torpedo Maculopathy Associated with Choroidal Neovascularization.

Background Torpedo maculopathy is a very rare, congenital, usually unilateral hypopigmented lesion in the temporal macula. Material and Methods This retrospective case series describes three patients with torpedo maculopathy. Results The first two cases demonstrate typical clinical and imaging findings of torpedo maculopathy in asymptomatic patients. The third case relates to a symptomatic young patient with a torpedo lesion, a smaller satellite lesion, and evidence of choroidal neovascularization confirmed by fluorescence angiography. In the area of the clinically visible torpedo lesion, spectral domain optical coherence tomography showed atrophy of the outer retina with increased choroidal signalling and a hyperreflective lesion above the retinal pigment epithelium suggestive of choroidal neovascularization. Fundus autofluorescence imaging revealed a hyperautofluorescent rim along the margin of the hypoautofluorescent torpedo lesion. Conclusion In the literature, torpedo lesions are usually regarded as benign lesions with no tendency for progression. The third case demonstrates that torpedo lesions may be associated with choroidal neovascularization, which has been successfully treated with anti-VEGF therapy.

Long-term efficacy of selective laser trabeculoplasty in patients on prostaglandin therapy.

BACKGROUND: The aim of the study was to analyse the efficacy of selective laser trabeculoplasty in patients on medical therapy and to evaluate a possible influence of prostaglandin therapy on intraocular pressure reduction. PATIENTS AND METHODS: A retrospective chart review was undertaken of patients with ocular hypertension or open angle glaucoma who underwent selective laser trabeculoplasty between 3/2008 and 12/2010. Data were collected preoperatively, on the day of intervention, 1 day, 1 month and then every 3 months post selective laser trabeculoplasty. The main outcome measure was mean intraocular pressure reduction. RESULTS: 109 eyes (76 on prostaglandins) were included. Mean preoperative intraocular pressure was 22.3 ± 4.5 mmHg (prostaglandin naïve) and 19.2 ± 4.8 mmHg (on prostaglandin) (p=0.003). Up to 1 year follow-up, intraocular pressure was statistically significantly reduced in both groups (p ≤ 0.019). Eyes with a higher preoperative intraocular pressure had a greater pressure reduction (Spearman rho=0.387, p=0.002). Eyes naïve to prostaglandins initially had a greater reduction in intraocular pressure, although after 1 year of follow-up the difference was no longer statistically significant. CONCLUSIONS: Selective laser trabeculoplasty significantly reduces intraocular pressure in patients already on medical therapy. A sustained influence of prostaglandin therapy on the efficacy of selective laser trabeculoplasty was not found.

Intravitreal anti-VEGF therapy for retinal macroaneurysm.

BACKGROUND: We evaluated the effect of intravitreal anti-vascular endothelial growth factor therapy using bevacizumab or ranibizumab for retinal macroaneurysms with macular exudation. METHODS: In a retrospective interventional case series patients with retinal macroaneurysms were treated with either 1.25 mg intravitreal bevacizumab or 0.5 mg ranibizumab as first-line therapy. Patients were imaged by fluorescein angiography and optical coherence tomography. Retreatment was performed in case of persistent intraretinal or subretinal fluid in optical coherence tomography. RESULTS: Ten patients (10 eyes) with macroaneurysm involving the macula were treated with an average of 3.0 intravitreal anti-vascular endothelial growth factor injections. Mean best corrected visual acuity of all patients improved by 17 letters from baseline to the last follow-up visit. In 7 out of 10 patients, the fovea was affected by a secondary edema. In cases with foveal involvement, central retinal thickness decreased from 366 µm at baseline to 266 µm at the last follow-up visit. In the course of treatment 8 out of 10 patients showed evidence of marked regression of macular exsudation. CONCLUSION: Intravitreal anti-vascular endothelial growth factor therapy appears to be a promising treatment alternative to laser treatment in cases of retinal macroaneurysms with macular exudation.

[Effectiveness of selective laser trabeculoplasty in patients with insufficient control of intraocular pressure despite maximum tolerated medical therapy]. / Wirksamkeit der selektiven Lasertrabekuloplastik bei Patienten mit unzureichender Augendrucksenkung unter maximaler Therapie.

BACKGROUND: Reduction of intraocular pressure (IOP) is still the primary goal of glaucoma treatment. The aim of this prospective study was to examine the IOP lowering effect of selective laser trabeculoplasty (SLT) in patients on maximum tolerated medical therapy (MTMT), especially with regard to a potential influence of pseudophakia and topical prostaglandin analogues (PGA) on IOP reduction. MATERIAL AND METHODS: A total of 30 patients with a diagnosis of primary open angle glaucoma, normal tension glaucoma and pseudoexfoliative glaucoma with uncontrolled IOP despite MTMT underwent SLT treatment circumferentially over 360°. Follow-up visits were conducted 1 day after SLT and then 1, 3, 6, 9, and 12 months post-treatment. The initial medication was continued unchanged for 3 months. RESULTS: Median follow-up was 11.97 ± 3.1 months, mean IOP at baseline was 19.60 ± 4.69 mmHg, mean IOP reduction was -19.95 ± 17.14% 1 month after and -14.07 ± 23.57% 12 months after SLT (p < 0.001 and p = 0.003, respectively). Patients with higher baseline IOP had greater reduction of IOP after SLT (R(2) = 0.482, p < 0.001). Phakic patients had a significantly greater IOP reduction compared to pseudophakic patients (- 4.55 ± 4.45 mmHg and + 2.75 ± 6.75 mmHg, respectively, p = 0.010). Patients without PGA had a statistically insignificant greater IOP reduction compared to patients with PGA (- 7.40 ± 4.72 mmHg and -2.48 ± 5.22 mmHg, respectively, p = 0.066) and four patients needed additional surgery to lower IOP. CONCLUSION: Even in patients already on maximum IOP lowering medication, SLT has the potential to significantly reduce IOP up to 1 year after treatment. The IOP reduction is most pronounced in phakic eyes with high preoperative IOP.

Multimodal imaging of autosomal dominant drusen.

BACKGROUND: Malattia Leventinese (ML) is a dominantly inherited macular dystrophy characterized by a radial pattern of drusen in the macular area and on the nasal edge of the optic disc. This case series describes the morphological features of drusen associated with ML using multimodal imaging. HISTORY AND SIGNS: Three patients (two of the same family but only one with the ML phenotype) were analyzed by multimodal imaging including spectral domain optical coherence tomography (SD OCT) and genetic testing. In two patients multiple drusen in the macular region and around the optic nerve head were observed bilaterally. A radial pattern was only seen in one patient. These drusenoid deposits showed early hyperfluorescence in fluorescein angiography (FA) and intense staining in indocyanine green angiography similar to cuticular drusen (basal laminar drusen). The corresponding SD OCT scan revealed two types of deposits. The first, more prominent type, were focal nodular sub-retinal pigment epithelium (RPE) deposits. The second type of deposit appears to be localized on the anterior part of the RPE comparable to subretinal drusenoid deposits (SDD; reticular pseudodrusen). THERAPY AND OUTCOME: A single nucleotide variation c.1033C>T (p.R345 W) in the EFEMP1 gene was found in case 1 (classic ML), but could not be detected in case 2 and 3. So far our patients have not suffered from any visual complaints and have not developed choroidal neovascularization. They will be followed up regularly. DISCUSSION: Multimodal imaging including SD OCT provided new information about the appearance of drusen in eyes with ML/early onset drusen. In addition to the sub-RPE deposits some deposits appear above the RPE, however have different characteristic findings on FA/ICG, autofluorescence, near infrared reflectance and blue light imaging than SDD observed in patients with age-related macular degeneration. SD OCT alone might not be sufficient to characterize these type of drusen in ML.
