Purpose: To ascertain the anatomic factors that help achieve non-surgical sealing in full thickness macular hole (FTMH).
Methods: Retrospective collaborative study of FTMH that closed without surgical intervention.
Results: A total of 78 patients (mean age 57.9 years) included 18 patients with blunt ocular trauma, 18 patients that received topical or intravitreal therapies and 42 patients with idiopathic FTMH. Mean±SD of the initial corrected visual acuity (VA) in logMAR improved from 0.65±0.54 to 0.34±0.45 (p<0.001) at a mean follow-up of 33.8±37.1 months. FTMH reopened in seven eyes (9.0%) after a mean of 8.6 months. Vitreomacular traction was noted in 12 eyes (15.8%), perifoveal posterior vitreous detachment in 42 (53.8%), foveal epiretinal membrane in 10 (12.8%), cystoid macular oedema (CME) in 49 (62.8%) and subretinal fluid (SRF) in 20 (25.6%). By multivariate analysis, initial VA correlated to the height (p<0.001) and narrowest diameter of the hole (p<0.001) while final VA correlated to the basal diameter (p<0.001). Time for closure of FTMH (median 2.8 months) correlated to the narrowest diameter (p<0.001) and the presence of SRF (p=0.001). Mean time for closure (in months) was 1.6 for eyes with trauma, 4.3 for eyes without trauma but with therapy for CME, 4.4 for eyes without trauma and without therapy in less than 200 µm in size and 24.7 for more than 200 µm.
Conclusion: Our data suggest an observation period in new onset FTMH for non-surgical closure, in the setting of trauma, treatment of CME and size <200 µm.

Purpose To analyze the recovery course of foveal microstructures in eyes with nonsurgical healing of full-thickness macular hole (FTMH). Methods By serial OCT scans, the temporal healing sequences were analyzed in ocular trauma, vitreomacular traction (VMT), cystoid macular edema (CME), and the remaining group. We evaluated correlations between the final best-corrected spectacle visual acuity and reconstruction time of external limiting membrane (ELM), and inner segment/outer segment (IS/OS). Results The healing (mean +/- standard deviation in months) most involved fusion at the level of the outer nuclear layer (ONL) (6.3 +/- 10.5) followed by restoration of ELM (9.1 +/- 13.8), and lastly, by IS/OS regeneration (13.1 +/- 19.5). In severe blunt ocular trauma, healing was fast and involved subretinal zipper glue-like reapposition with resulting outer retinal atrophy. Best spectacle-corrected visual acuity correlated with normalization of the clivus (p=0.012), faster ELM (p=0.006), and IS/OS reconstitution (p=0.024). Recurrence of FTMH occurred when the healing was halted (3 eyes) or was aberrant by lamellar hole epiretinal proliferation (LHEP) (3 eyes) or by the persistence of VMT (1 eye). Conclusion Recovery sequences proceeded from the ONL to the deeper layers with BCVA correlating absolutely and temporally with the restoration of outer retinal layer integrity.

Two controlled, prospective, randomized, single-blind studies were performed. In the first study, a total of 80 eyes from 40 outpatient-clinic patients were analyzed. PT drops were applied to the right eye, and a MY device was inserted in the left eye for 30min. Time until maximal pupil dilation for each eye was then assessed. In the second study, 80 eyes from 80 patients undergoing cataract surgery were analyzed. Pupil dilation was achieved using either PT drops three-times for one hour prior to surgery (40 patients), or a MY device was inserted one hour prior to surgery (40 patients).
In the first study, MY achieved superior mydriasis compared to PT eye drops at 90min (9.04±1.33mm vs 8.78±1.37mm, P=0.012). However MY took longer than PT drops to achieve maximal dilation, and mydriasis was inferior in eyes with MY compared to PT drops at 30min (7.21±1.73mm vs 8.22±1.43mm, P<0.001), the two groups only becoming similar by 60min (8.85±1.44mm vs 8.71±1.27mm, P=0.236). In the second study, both MY and PT achieved similar levels of mydriasis at the beginning of surgery (8.75±0.76mm with MY vs 8.77±0.63mm with PT), and also at the end of surgery (7.96±1.06mm with MY vs 8.32±0.72mm with PT), with no significant difference between groups (P=0.08). MY was well tolerated and cardiovascular effects were not influenced by dilation method.

TGF-ß inhibition with these peptides represents a promising new therapeutic line for CNV targeting a different pathway than current therapies. More studies are needed to assess this effect on early CNV, alone or in combination with anti-VEGF.

Purpose. To estimate the prevalence and causes of bilateral blindness and visual impairment in an urban institutionalized population aged 65 years and older.
Methods. A total of 392 nursing home residents completed a standardized eye examination, including measurement of visual acuity (VA), intraocular pressure, lens opacity grading, indirect ophthalmoscopy, and photography of the macular area. The major causes of vision loss identified for all participants were blindness and visual impairment.
Results. The average subject age was 82 years (65¿97); women outnumbered men 263 to 129. The prevalence of bilateral blindness (VA ¿1.0 logarithm of the minimum angle of resolution [logMAR]) was 14.9% (43/288); the prevalence of visual impairment (VA ¿0.5 and 1.0 logMAR) was 31.9% (92/288). Blindness and visual impairment increased significantly with age (p<0.05), odds ratio (OR) 1.047 and 1.088, respectively. Cataract was the most common cause of bilateral blindness and visual impairment (27.9% and 44.6%, respectively) followed by pathologic myopia (23.3%) and age-related macular degeneration (AMD) (20.9%) for blindness, and by AMD (27.2%) and pathologic myopia (12%) for visual impairment. Fifty percent of subjects with visual loss had the potential for improved vision with medical or surgical intervention.
Conclusions. Although the prevalences were high, these data are important since it is difficult for epidemiologic studies to include aged, institutionalized individuals, although their numbers are increasing. Recognition of the predominant causes of visual loss dependent on age is fundamental for early diagnosis and treatment of ocular diseases. Many cases of low vision can be treated with appropriate ophthalmologic care.

The temporal pole (TP) is the rostralmost portion of the human temporal lobe. Characteristically, it is only present in human and nonhuman primates. TP has been implicated in different cognitive functions such as emotion, attention, behavior, and memory, based on functional studies performed in healthy controls and patients with neurodegenerative diseases through its anatomical connections (amygdala, pulvinar, orbitofrontal cortex). TP was originally described as a single uniform area by Brodmann area 38, and von Economo (area TG of von Economo and Koskinas), and little information on its cytoarchitectonics is known in humans. We hypothesize that 1) TP is not a homogenous area and we aim first at fixating the precise extent and limits of temporopolar cortex (TPC) with adjacent fields and 2) its structure can be correlated with structural magnetic resonance images. We describe here the macroscopic characteristics and cytoarchitecture as two subfields, a medial and a lateral area, that constitute TPC also noticeable in 2D and 3D reconstructions. Our findings suggest that the human TP is a heterogeneous region formed exclusively by TPC for about 7 mm of the temporal tip, and that becomes progressively restricted to the medial and ventral sides of the TP. This cortical area presents topographical and structural features in common with nonhuman primates, which suggests an evolutionary development in human species.
