RESUMO
PURPOSE: To assess one year results and stability of the implantation of a scleral anchored intraocular lens (IOL). DESIGN: Interventional prospective case series. METHODS: Sixty eyes of 60 patients affected by either aphakia or IOL dislocation were included in this study. Patients underwent vitrectomy, scleral fixation of the IOL, and, if present, dislocated IOL removal. Patients were evaluated preoperatively and at 1, 3, 6, and 12 months after surgery by best-corrected distance visual acuity (BCVA) assessment, intraocular pressure (IOP) measurement, corneal specular microscopy, and optical coherence tomography (OCT) of both the macula and anterior segment. RESULTS: At twelve months, mean BCVA significantly improved (p < 0.0001), and none of the patients experienced a decrease of visual acuity. A 10% decrease of endothelial cell count occurred after surgery. Cystoid macular edema occurred in three patients (5%). A transient increase of intraocular pressure was noted in 7 cases (12%). At one month, horizontal and vertical IOL tilt was 1.04 ± 0.87 and 0.74 ± 0.71 degrees, respectively, and did not significantly change in the follow-up (p > 0.05). None of the patients had decentration or dislocation of scleral-fixated IOL during the follow-up. CONCLUSION: Implantations of scleral plug fixated IOL provide good visual results, low complication rate, and excellent stability of the lens until one-year follow-up.
RESUMO
PURPOSE: To report the case of a 33-year old man who disclosed the first case of bilateral ocular involvement of hand, foot, and mouth disease (HFMD) with a different stage of the disease in each eye. METHODS: Retrospective case report. RESULTS: The study included a patient who incurred in a bilateral HFMD maculopathy. During 6 months follow-up period persistent abnormalities in fundus examination and in OCT scans were reported. CONCLUSION: We consider that our case shows that choriocapillaris is the primary target of HFMD maculopathy, for this reason we consider that ICGA is mandatory for early diagnosis and an effective treatment.
RESUMO
PURPOSE: To evaluate the clinical outcome of surgical treatment for macular serous detachment associated with optic disc pit with pars plana vitrectomy (PPV) without laser photocoagulation on the temporal edge. METHODS: Vitrectomy was performed in 8 eyes of 8 patients (mean age 27.25 years; range 12-57 years) with unilateral macular detachment associated with optic disc pit. All patients underwent pars plana vitrectomy (cases 1, 2, 3, and 4, PPV 20 G; cases 5, 6, 7, and 8, PPV 25 G), internal limiting membrane (ILM) peeling, and SF6 20% gas tamponade (case 1 was treated with silicone oil tamponade). Endolaser on the temporal margin of the optic disk was not performed. Every patient was observed for a follow-up period of 59.25 months after surgery. Statistical analysis was carried out using Student t test paired data. p Value <0.05 was considered to be significant. RESULTS: Complete retinal reattachment was achieved in 7 of 8 patients. Case 8 was operated 11 months ago and he still has a small area of subretinal fluid not completely reabsorbed. Mean preoperative best-corrected visual acuity (BCVA) was 20/83 and the mean postoperative BCVA was 20/40. Mean preoperative foveal thickness was 973 µm and mean postoperative foveal thickness was 363.5 µm. Case 7 developed a macular hole after treatment. CONCLUSIONS: Pars plana vitrectomy, ILM peeling, and endotamponade (SF6 20% gas) without endolaser on the temporal edge of optic disc is an effective treatment. This procedure achieved successful anatomical and functional results.

A 58-year-old woman presented with a problem with her peripheral vision. Computed tomography scan showed an occipital hemorrhagic stroke. She subsequently suffered gastrointestinal bleeding and at surgery biopsy of a portion of the middle colic artery aneurysm revealed changes consistent with polyarteritis nodosa.

Trabecular meshwork (TM) cells are now considered to play an active role in the aqueous outflow mechanism because they exhibit smooth muscle-like contractile properties. Endothelin-1 (ET-1), a potent vasoconstrictor peptide, has been proposed to play a role in the local regulation of aqueous outflow and intraocular pressure (IOP) control. We propose an in vitro culture model as a method for the study of ET-1-induced human TM (HTM) cell contractility and for the study of whether pre-incubation with flunarizine, a calcium-channel blocker, can inhibit the action of ET-1. Experiments were performed on semiconfluent HTM cells (primary cultures established from normotensive human donor eyes) at the second passage, with phosphate-buffered saline (PBS) as a control. The contractile status of the cells was evaluated by a morphometric analysis of cell area, assuming that HTM cells in culture are able to reduce their area as a consequence of cytoskeletal contraction, rather than regulatory volume decrease. After incubation with 10 microM ET-1 for 5 mins, we observed a reduction of HTM cell area with respect to PBS-treated cells: 2425 +/- 876 microm2 versus 3125 +/- 987 microm2 (P < 0.001); and cells exhibited a retraction in shape and a reduction in number of indented profiles. Administration of ET-1 at progressively lower doses produced a corresponding lower reduction of HTM cell area, suggesting a dose-response effect of ET-1. Pre-incubation with 10 microM flunarizine strongly inhibited the ET-1 effect on HTM cell contraction: 2806 +/- 865 microm2 versus 2910 +/- 846 microm2 (P = not significant). Our data indicate that ET-1 induced a statistically significant reduction in the area of HTM cells versus controls, and that ET-1 can directly influence the aqueous outflow. Moreover, we observed that flunarizine inhibited the effect of ET-1 on the HTM cells.
