Three-Month Safety and Efficacy Outcomes for the Smaller-Incision New-Generation Implantable Miniature Telescope (SING IMT™).

The smaller-incision new-generation implantable miniature telescope (SING IMT™) is the second generation of the IMT™, a telescope prosthesis that is indicated for monocular implantation in patients with stable vision impairment caused by bilateral central scotomas associated with end-stage Age-related macular degeneration (AMD). This non-comparative retrospective study is the first and largest single-surgeon case series to evaluate the short-term (3 months) safety and efficacy of the device in patients with disciform scars or geographic atrophy at baseline. The main outcome measures included best-corrected distance and near visual acuity (CDVA and CDNVA, respectively), endothelial cell density (ECD) loss, and the incidence of complications. At postoperative month 3 in the study eyes, mean CDVA and CDNVA improved by +14.9 ± 7.1 letters and +7.7 ± 3.2 Jaeger levels, respectively. Importantly, 70.83% of patients gained ≥ 2 lines, 58.33% ≥ 3 lines, and 25.00% ≥ 4 lines of CDVA. From baseline, ECD loss in the study eyes was 10.4 ± 13.3% at 3 months, however, ECD was comparable between the study and fellow eyes at all time points. The most common complication was corneal edema. In all, these short-term outcomes suggest that the SING IMT™ delivers lower ECD loss than the first-generation IMT ™, but similar visual outcomes and safety.

Optical coherence tomography angiography in Bietti crystalline dystrophy.

PURPOSE: Bietti crystalline dystrophy (BCD) is a rare autosomal recessive retinal dystrophy caused by pathogenic variants of CYP4V2 gene and characterized by shiny yellow deposits in the retina and progressive atrophy of the retinal pigment epithelium (RPE) and choriocapillaris. The main aim of the present study is to describe the optical coherence tomography angiography (OCTA) characteristics of a patient affected by BCD. METHODS: A 59-years-old female with genetically confirmed BCD underwent an ophthalmological examination complete of OCTA performed in the atrophic retina, the junctional zone and the apparently normal retina. The area of choriocapillaris (CC) atrophy was compared to the area of RPE atrophy on fundus autofluorescence (FAF) imaging. RESULTS: A severe vessel density (VD) deficit at the level of superficial and deep capillary plexa as well as CC was registered in atrophic areas, which resulted deeper with respect to the junctional area, whereas the apparently preserved retina revealed VD values similar to that of control eyes. The area of RPE atrophy on FAF was larger (55.90 mm2 in right eye and 48.76 mm2 in left eye) than the area of CC atrophy on OCTA imaging (51.86 mm2 and 42.44 mm2 respectively in right and left eye). CONCLUSIONS: Our findings suggest that VD impairment of retinal plexa and CC follows the degeneration of RPE as demonstrated by the greater size of the area of RPE atrophy compared to CC atrophy. Further investigations based on OCTA imaging are necessary to enhance our knowledge of this rare disease.

Retinal vascular impairment in Wolfram syndrome: an optical coherence tomography angiography study.

To evaluate differences in macular and optic disc circulation in patients affected by Wolfram Syndrome (WS) employing optical coherence tomography-angiography (OCTA) imaging. In this retrospective study, 18 eyes from 10 WS patients, 16 eyes of 8 patients affected by type I diabetes and 17 eyes from 17 healthy controls were enrolled. All patients were imaged through OCT and OCTA and vascular parameters, as perfusion density (PD) and vessel length density (VLD) were measured. OCTA showed reduced PD in WS patients at the macular superficial capillary plexus (SCP, 27.8 ± 5.3%), deep vascular complex (DVC, 33.2 ± 1.9%) and optic nerve head (ONH, 21.2 ± 9.1%) compared to both diabetic patients (SCP 33.9 ± 1.9%, P < 0.0001; DVC 33.2 ± 0.7%, P = 1.0; ONH 33.9 ± 1.3, P < 0.0001) and healthy controls (SCP 31.6 ± 2.5, P = 0.002; DVC 34.0 ± 0.7%, P = 0.089; ONH 34.6 ± 0.8%, P < 0.0001). Similarly, VLD was lower in WS patients at the SCP (10.9 ± 2.7%) and ONH levels (7.5 ± 4.1%) compared to diabetic patients (SCP 13.8 ± 1.2%, P = 0.001; DVC 13.8 ± 0.2%, P < 0.0001; ONH 13.0 ± 0.7%, P = < 0.0001), but higher in DVC (15.7 ± 1.2%, P < 0.0001). Furthermore, VLD was lower in WS patients in all the vascular parameters compared to controls (SCP 13.8 ± 1.5%, P < 0.0001; DVC 17.3 ± 0.6%, P < 0.0001; ONH 15.7 ± 0.5%, P < 0.0001). A significant microvasculature impairment in the macular SCP and ONH microvasculature was demonstrated in eyes affected by WS. Microvascular impairment may be considered a fundamental component of the neurodegenerative changes in WS.

Cleft Lip and Palate Repair.

INTRODUCTION: Cleft lip and palate is the most frequent congenital craniofacial deformity. In this article, the authors describe their experience with cleft lip and palate repair. METHODS: Data regarding patients presenting with primary diagnosis of cleft lip and/or palate, between 2009 and 2015, were reviewed. Details including demographics, type of cleft, presence of known risk factors, surgical details, and follow-up visits were collected. Documented complications were reported. Caregivers' satisfaction was assessed with a survey. The survey used to assess satisfaction with cleft-related features was based on the cleft evaluation profile (CEP). In addition, 4 assessors used visual analog scale (VAS) to assess the aesthetic satisfaction. RESULTS: Seven hundred fifty-two patients with primary diagnosis of cleft lip and/or palate underwent surgical correction at "S. Chiara" Hospital, 432 (57.45%) male and 320 (42.55%) female. The most common cleft types in our study were incomplete cleft palate (152 patients) and left unilateral complete cleft lip and palate (152 patients). Associated syndromes were found in 46 patients (6.12%). Cleft lip was repaired using a modified Tennison-Randall technique when the defect was unilateral, whereas a modified Mulliken technique was used for bilateral cleft lip. Cleft palate was repaired using the Bardach technique or Von Langenbeck technique at 5 to 6 months of age. Cleft lip and palate was repaired in several surgical steps. In total, complications were reported in 81 of 752 patients (14.16%). Average fathers' satisfaction score assessed using CEP was 4.5 (lip), 4.8 (nose), 4.7 (teeth), 4.8 (bite), 4.2 (breathing), 4.6 (profile). Average mothers' satisfaction score assessed using CEP was 4.3 (lip), 4.6 (nose), 4.4 (teeth), 4.5 (bite), 4.1 (breathing), 4.4 (profile). Average level of aesthetic satisfaction, assessed using VAS, was 8.7 (fathers), 8.1 (mothers), 7.9 (lay person), and 8.0 (senior cleft surgeon). CONCLUSION: The multidisciplinary management of children with oral cleft determinated good results, in terms of satisfaction and aesthetic appearance. From our experience, periosteoplasty and lip-adhesion are key surgical techniques.
